    A buld-it-yourself solar still(蒸馏器) is one of the best ways to obtain drinking water in areas where the liquid is not readily available. Developed by two doctors in the U.S. Department of Agriculture, it’s an excellent water collector. Unfortunately, you must carry the necessary equipment with you, since it’s all but impossible to find natural substitutes. The only components required, though, are a 5’ 5’ sheet of clear or slightly milky plastic, six feet of plastic tube, and a container perhaps just a drinking cup to catch the water. These pieces can be folded into a neat little pack and fastened on your belt.

        To construct a working still, use a sharp stick or rock to dig a hole four feet across and three feet deep. Try to make the hole in a damp area to increase the water catcher’s  productivity. Place your cup in the deepest part of the hole. Then lay the tube in place so that one end rests all the way in the cup and the rest of the line runs up and out the side of the hole.

       Next, cover the hole with the plastic sheet, securing the edges of the plastic with dirt and weighting the sheet’s center down with a rock. The plastic should now form a cone(圆锥体) with 45-degree-angled sides. The low point of the sheet must be centered directly over, and no more than three inches above, the cup.

       The solar still works by creating a greenhouse under the plastic. Ground water evaporates (蒸发) and collects on the sheet until small drops of water form, run down the material and fall off into the cup. When the container is full, you can suck the refreshment out through the tube, and won’t have to break down the still every time you need a drink.

    32.What do we know about the solar still equipment from the first paragraph?

    A.It’s delicate.                  B.It’s expensive.

    C.It’s complex.                  D.It’s portable

    33.What does the underlined phrase “the water catcher” in paragraph 2 refer to?

    A.The tube                         B.The still

    C.The hole                         D.The cup

    34.What’s the last step of constructing a working solar still?

    A.Dig a hole of a certain size                     B.Put the cup in place

    C.Weight the sheet’s center down                  D.Cover the hole with the plastic sheet

    35.When a solar still works, drops of water come into the cup form          .

    A.the plastic tube                       B.outside the hole

    C.the open air                          D.beneath the sheet

    Old Problem, New Approaches

           While clean energy is increasingly used in our daily life, global warning will continue for some decades after CO2 emissions(排放) peak. So even if emission were to begin decrease today, we would still face the challenge of adapting to climate. Here I will stress some smarter and more creative examples of climate adaptation.

           When it comes to adaptation, it is important to understand that climate change is a process. We are therefore not talking about adapting to a new standard, but to a constantly shifting set of conditions. This is why in part at least, the US National Climate Assessment says that: “there is no ‘one-size fit all’ adaptation.” Nevertheless, there are some actions that offer much and carry little risk or cost.

          Around the world people are adapting in surprising ways, especially in some poor countries, Floods have some more damaging in Bangladesh in recent decades. Mohammed Rezwan saw opportunity where others saw only disaster. His not-for-profit organization runs 100 river boats that server as floating libraries, schools, and health clinics, and are equipment with solar panels and other communication facilities. Rezwan is creating floating connectivity (连体) to replace flooded roads and highways. But he is also working at a far more fundamental level: his staff people how to make floating gardens fish ponds prevent starvation during the wet season.

    Around the world, people are adapting in surprising ways, especially in some poor countries, Fllods have become more damaging in Bangladesh in recent decades. Mobammed Rezwan saw opportunity where others saw only disaster. His not-for-profit organization runs 100 river boats that serve as floating libraries, schoods, and health clinics, and are equipped with solar panels and other communicating facilities. Rezwan is creating floating conmetivity(连接) to replace flooded roads and highways. But he is also working at a far more fundamental level: his staff show people how to make floating gardens and fish ponds to prevent starvation during the wet season.

    Elsewhere in Asia even more astonishing actions are being taken. Chewang. Nophel lives in a mountainous region in India, where he is known as the Ice Man. The loss of glaciers(冰川)there due to global warming represents an enormous threat to agriculture. Without the glaciers, water will arrive in the rivers at times when it can damage crops. Norphel’s inspiration come from seeing the waste of water over winter, when it was not needed. He directed the wasted water into shallow basins where it froze, and was stored until the spring. His fields of ice supply perfectly timed irrigation(灌溉) water. Having created nine such ice reserves. Nophel calculates that he has stored about 200, 000mof water. Climate change is a continuing process, so Norhel’s ice reserves will not last forever. Warming will overtake them. But he is providing a few years during which the farmers will, perhaps, be able to find other means of adapting.

    Increasing Earth’s reflectiveness can cool the planet. In southern Spain the sudden increase of greenhouses (which reflect light back to space) has changed the warming trend locally, and actually cooled the region. While Spain as a whole is heating up quickly, temperatures near the greenhouses have decreased. This example should act as an inspiration for all cities. By painting buildings white, cities may slow down the warming process.

    In Peni, local farmers around a mountain with a glacier that has already fallen victim to climate change have begun painting the entire mountain peak white in the hope that the added reflectiveness will restore the life-giving ice. The outcome is still far from clear, But the World Bank has included the project on its of ‘100 ideas to save the planet”.

    More ordinary forms of adaptation are happening everywhere. A friend of mine owns an area of land in western Victoria. Over five generations the land has been too wet for cropping. But during the past decade declining rainfall has allows him to plant highly profitable crops. Farmers in many countries are also adapting like this—either by growing new produce, or by growing the same things differently. This is common sense, But some suggestions for adapting are not. When the polluting industries argue that we’ve lost the battle to control carbon pollution and have no choice but to adapt, it’s a nonsense designed to make the case for business as usual.

    Human beings will continue to adapt to the changing climate in both ordinary and astonishing ways. But the most sensible form of adaptation is surely to adapt our energy systems to emit less carbon pollution. After all, if we adapt in the way, we may avoid the need to change in so many others.

    65.The underlined part in Paragraph 2 implies        .

    A. adaptation is an ever-changing process                    B. the cost of adaptation varies with time

    C. global warming affects adaptation forms                  D. adaptation to climate change is challenging

    66.What is special with regard to Rezwan’s project?

    A. The project receives government support.                B. Different organizations work with each other.

    C. His organization makes the best of a bad situation.    D. The project connects flooded roads and highways.

    67.What did the Ice Man do to reduce the effect of global warming?

    A. Storing ice for future use.                                      B. Protecting the glaciers from melting.

    C. Changing the irrigation time.                                   D. Postponing the melting of the glaciers.

    68.What do we learn from the Peru example?

    A. White paint is usually safe for buildings.                   B. The global warming tread cannot be stopped.

    C. This country is heating up too quickly.                            D. Sunlight reflection may relieve global warming.

    69.According to the author, polluting industries should       .

    A. adapt to carbon pollution                                        B. plant highly profitable crops

    C. leave carbon emission alone                                    D. fight against carbon pollution

    70.What’s the author’s preferred solution to global warming?

    A. setting up a new standard.                                      B. Reducing carbon emission.

    C. Adapting to climate change.                                    D. Monitoring polluting industries.

    In 2013, Bezos, the CEO and founder of Amazon Inc., made headlines when he announced that within a few years, the company would use unmanned drones(无人机)to deliver packages within 30 minutes after an order was placed. Since Amazon Prime Air was publicized the night before “Cyber Monday,” some just regarded it apublicity stunt(噱头) designed to draw attention to the company. It turns out they were wrong.

    On December 7, 2016, Amazon revealed that it had completed its first Prime Air delivery in Cambridge, UK. The package, containing a bag of popcorn and an Amazon Fire TV, were loaded on to the unmanned vehicle from a local fulfillment center and delivered to a two-story farmhouse several miles away – all within 13 minutes after the items were bought!

    The company also announced that the service is now available within the five-square-mile range of the Cambridge area, seven days a week during daylight hours. The thinly populated rural area, with few dozen residents distributed amidst vast areas of farmland and fields, is perfect for testing the drones.

    Unfortunately, even if the trial is wildly successful, many challenges still remain before drone delivery becomes a reality for most of us. While the drone may do fine in rural areas, they remain untested in crowdedurban cities where they would bump into barriers like buildings or trees. There is also fear that theautonomous flying vehicles could injure people as they come down to drop their packages. The drones and their load are also damaged by destroyers.

      Then there are the delivery logistics(后勤保障). Amazon will not only have to ensure that every Prime Air customer has a special landing flat surface, but also come up with a practical solution for apartment residents who do not have accessto an open space where the drone can land. Hence, while Amazon Prime Air may someday be a reality, for now, we will just have to wait for two “long” days to receive our packages!

    28. Why was the trial carried out in Cambridge area?

    A. Amazon couldn’t find out drone landing space in crowded urban cities.

    B. The vast rural areas with smaller population were perfect test sites.

    C. Drone flight was prohibited where there were impassable barriers.

    D. The company had many logistics to guarantee service quality there.

    29. It can be inferred from the text that _________.

    A. the new service will save customers more time and money.

    B Amazon is the early pioneer of drone flight in the world

    C universal drone package delivery has still a long way to go

    D the injuries by drones have got the local residents in panic

    30.What is the main idea of the text?

    A. Drone delivery reached customers in a shorter time.

    B Bezos tried to expand its delivery service in Cambridge.

    C. Amazon was the first company to use drone technology.

    D Amazon tried to deliver package to customers by drone.

    The meaning of silence varies among cultural groups. Silences may be thoughtful, or they may be empty when a person has nothing to say. A silence in a conversation may also show stubbornness, or worry. Silence may be viewed by some cultural groups as extremely uncomfortable; therefore attempts may be made to fill every gap(间隙) with conversation. Persons in other cultural groups value silence and view it as necessary for understanding a person's needs.

    Many Native Americans value silence and feel it is a basic part of communicating among people, just as some traditional Chinese and Thai persons do. Therefore, when a person from one of these cultures is speaking and suddenly stops, what maybe implied(暗示) is that the person wants the listener to consider what has been said before continuing. In these cultures, silence is a call for reflection.

    Other cultures may use silence in other ways, particularly when dealing with conflicts among people or in relationships of people with different amounts of power. For example, Russian, French, and Spanish persons may use silence to show agreement between parties about the topic under discussion. However, Mexicans may use silence when instructions are given by a person in authority rather than be rude to that person by arguing with him or her. In still another use, persons in Asian cultures may view silence as a sign of respect, particularly to an elder or a person in authority.

    Nurses and other care-givers need to be aware of the possible meanings of silence when they come across the personal anxiety their patients may be experiencing. Nurses should recognize their own personal and cultural construction of silence so that a patient’s silence is not interrupted too early or allowed to go on unnecessarily. A nurse who understands the healing(治愈) value of silence can use this understanding to assist in the care of patients from their own and from other cultures.

    32. What does the author say about silence in conversations?

    A. It implies anger.

    B. It promotes friendship.

    C. It is culture-specific.

    D. It is content-based.

    33. Which of the following people might regard silence as a call for careful thought?

    A. The Chinese.

    B. The French.

    C. The Mexicans.

    D. The Russians.

    34. What does the author advise nurses to do about silence?

    A. Let it continue as the patient pleases.

    B. Break it while treating patients.

    C. Evaluate its harm to patients.

    D. Make use of its healing effects.

    35. What may be the best title for the text?

    A. Sound and Silence

    B. What It Means to Be Silent

    C. Silence to Native Americans

    D. Speech Is Silver; Silence Is Gold

       Next time a customer comes to your office, offer him a cup of coffee. And when you’re doing your holiday shopping online, make sure you’re holding a large glass of iced tea. The physical sensation(感觉)of warmth encourages emotional warmth, while a cold drink in hand prevents you from making unwise decisions—those are the practical lesson being drawn from recent research by psychologist John A. Bargh.

    Psychologists have known that one person’s perception(感知)of another’s “warmth” is a powerful determiner in social relationships. Judging someone to be either “warm” or “cold” is a primary consideration, even trumping evidence that a “cold” person may be more capable. Much of this is rooted in very early childhood experiences, Bargh argues, when babies’ conceptual sense of the world around them is shaped by physical sensations, particularly warmth and coldness. Classic studies by Harry Harlow, published in 1958, showed monkeys preferred to stay close to a cloth “mother” rather than one made of wire, even when the wire “mother” carried a food bottle. Harlow’s work and later studies have led psychologists to stress the need for warm physical contact from caregivers to help young children grow into healthy adults with normal social skills.

    Feelings of “warmth” and “coldness” in social judgments appear to be universal. Although no worldwide study has been done, Bargh says that describing people as “warm” or “cold” is common to many cultures, and studies have found those perceptions influence judgment in dozens of countries.

    To test the relationship between physical and psychological warmth, Bargh conducted an experiment which involved 41 college students. A research assistant who was unaware of the study’s hypotheses(假设), handed the students either a hot cup of coffee, or a cold drink, to hold while the researcher filled out a short information form: The drink was then handed back. After that, the students were asked to rate the personality of “Person A” based on a particular description. Those who had briefly held the warm drink regarded Person A as warmer than those who had held the iced drink.

    “We are grounded in our physical experiences even when we think abstractly,” says Bargh.

    32. The author mentions Harlow’s experiment to show that ______.

    A. adults should develop social skills

    B. babies need warm physical contact

    C. caregivers should be healthy adults

    D. monkeys have social relationships

    33. In Bargh’s experiment, the students were asked to ______.

    A. evaluate someone’s personality

    B. write down their hypotheses

    C. fill out a personal information form

    D. hold coffee and cold drink alternatively

    34. We can infer from the passage that ______.

    A. abstract thinking does not come from physical experiences

    B. feelings of warmth and coldness are studied worldwide

    C. physical temperature affects how we see others

    D. capable persons are often cold to others

    35. What would be the best title for the passage?

    A. Drinking for Better Social Relationships.

    B. Experiments of Personality Evaluation.

    C. Developing Better Drinking Habits.

    D. Physical Sensations and Emotions.

        In the age of the social network, there’s definitely such a thing as sharing too much; when it comes to losing weight, sharing could be key, though.

    A new Northwestern University study published in the Journal of the Royal Society Interface found that those who had an active hand in such online communities lost a higher percentage of their body weight compared to users who participated sparingly.

    Scientists analyzed data from people paying a membership fee on Calorieking. Com, which permits them access to weight-loss tools (like a food journal) and an online club. While the identity of each user remained confidential, the researchers had access to age, sex, height, initial weight and time-stamped activities. They could also monitor members’ recorded weigh-ins, friend requests and community arrangement, though they could not read any of the actual conversations between users.

    The researchers discovered that the users who recorded their weight and established close relations with other members were more likely to achieve their goals of ridding themselves of pounds. The most active users lost more than 8 percent of their body weight in a six-month period. The least active users, those with the fewest online friends and social interactions, lost around 5 percent of their body weight in the same period of time. The researchers theorize that participation plays a key role in weight loss because it offers an always-accessible network of support.

    They’re also looking ahead: The positive results point to sensible uses for social networks in other areas of health. Online communities might be successful alternatives for minor illnesses like discouragement and alcoholism, for which in-person meetings are often suggested. Modern life is so complex and stressful, and to go somewhere for a meeting is often not practical, Luis A. Nunes Amaral, senior author of the study, said in a statement. It is hopeful that this alternative approach of going online for support could work.

    42. In which column of a magazine should the text be seated?

    A. Entertainment.           B. Fitness.          C. Technology.          D. Medicine.

    43.Who would lose more weight according to the new study?

    A. People frequently making online friends.

    B. Network users sparing time to surf the Internet.

    C. Members affording payments on Calorieking.com.

    D. Fellows regularly taking part in community activities.

    44. What can we learn from the 4th paragraph?

    A. Scientists ought to pay for the online data they study.

    B. Researchers can manage to know more of the users besides their names.

    C. People’s active online communications matter in their losing weight.

    D.The most active users lost 3% more of their weight than the least active ones within half a year.

    45.What is Amaral’s attitude toward online communities?

    A. Anxious.               B. Optimistic.            C. Undoubted.          D. Impractical.

          Man is a land animal, but he is also closely tied to the sea. Throughout history the sea has served the needs of man. The sea has provided man with food and a convenient (便利的) way to travel to many parts of the world. Today, nearly two-thirds of the world’s population live within 80 kilometers of the sea coast.
          In the modern technological world, the sea offers many resources to help mankind survive (=continue to live). Resources on land are beginning to be used up. The sea, however, still can be hoped to supply many of man’s needs.
          The list of riches of the sea yet to be developed by man’s technology is impressive. Oil and gas explorations (
    探险) have been carried out for nearly 30 years. Valuable amounts of minerals exist on the ocean floor ready to be mined (开采).
          Fish farming promises to be a good way to produce large quantities of food. The culture of fish and shellfish (
    贝类动物) is an ancient skill practiced in the past mainly by Oriental people.
          Besides oil and gas, the sea may offer new sources of energy. Experts believe that the warm temperature of the ocean can be used in a way similar to the steam in a steamship. Ocean currents (
    水流) and waves offer possible use as a source of energy.
          Technology is enabling man to explore (
    勘探) ever more deeply under the sea. The development of strong, new materials has made this possible.
          The technology to harvest the sea continues to improve. Experts believe that by the year 2000 the problems that prevent us from exploiting fully the food, minerals, and energy sources of the sea will be largely solved.


    60. The major things that the sea offers man are ______.
       A. fish and oil             B. minerals and oil
       C. warm temperature and ocean currents 

    D. the food, energy sources, and minerals


    61. The sea serves the needs of man because ______.
       A. in provides man with food      B. it offers oil to man
       C. it supplies man with minerals    D. all of the above


    62. We can conclude from this passage that ______.
       A. the sea resources have largely been used up
       B. the sea, in the broad sense, has not yet been developed
       C. the problems that prevent us from using the food, minerals, and energy   

    sources of the sea have already been solved.
       D. by the year 2000 , the technology will be good enough to exploit all the  sea resources


    63. The underlined words Oriental people in the fourth paragraph probably mean ______.
       A. the people in Asia           B. African people
       C. European people             D. American people


    64. The best title for this passage is ______.
       A. Sea Harvest               B. Sea Food
       C. Technology for Exploiting the Sea    D. Man and the Sea

    "Today, technical innovations dominate our everyday life in many areas. New technologies, however, always are associated with risks -- and these are also seen by laymen," says Christoph Böhmert, first author of the recently published study and researcher of the Science Communication Group of KIT's Institute for German Studies. "It is crucial to enable adequate communication between science and society, which does not only consider scientific findings, but also concerns of the population." The study clearly showed that communication of risks may be complicated sometimes. Information on efficient precautions was found to lead to an increased risk perception by the recipients of the information.

    In their study, the researchers analyzed communication about a technology that has become indispensable in our life -- mobile communications and the electromagnetic fields (电磁场)on which it is based. All over the world, radiation protection authorities, such as the German Federal Office for Radiation Protection, communicate the current state of research into risks of electromagnetic fields as follows: Investigations made and all findings obtained so far do not allow any conclusions to be drawn with respect to mobile communications being a risk for human health. But, the experts continue, there still are knowledge gaps as regards long-term impacts. Then, measures are recommended to reduce exposure of the individual to electromagnetic fields.

    It had been known from previous studies already that information on precautions may increase worries. It had been suspected that people conclude from the recommendation of precautions that there really is a risk. This effect was not confirmed by the recent study. The scientists rather attributed the increased worries to a lack of knowledge about the propagation(传播) of electromagnetic fields.

    Within the framework of the study, the recommended precautions were submitted to 1717 Australians, together with one of six information brochures providing scientific background information. When test persons were given not only the recommendations, but also explained why observation of these tips strongly reduces their exposure to electromagnetic fields, worries increased. For example, scientists explained to the test persons that telephone conversations with a headset largely reduce exposure. When a mobile phone is located ten centimeters instead of just one centimeter away from the ear, the electric power absorbed by the ear is about one hundredth of the initial value. Hence, the own mobile phone usually causes an exposure that by far exceeds that of mobile communications stations that are generally referred to as "cellphone towers." While the scientists wanted to explain the effectiveness of precautions, test persons mainly considered this information to be an indication of their mobile phone -- not the transmission towers -- being dangerous. As a result, they perceived increased risk potentials for telephone conversations with their mobile phones.

    "The study reveals that messages on precautions and information are a double-edged sword in terms of subjective risk perception. Their use should be far better understood," Boehmert says.

    63. Which of the following statements is TRUE according to the passage ?

    A. Adequate information on efficient precautions can relieve the concerns of the public

    B.  Mobile communications definitely do harm to people’s health in the long run.

    C.  Information about technologies and their risks may have undesired side effects.

    D.  Observation of the precautions can help reduce the concerns of the public

    66.  According to the passage ,we can conclude that the best way to relieve the inappriate worries is to __________.

    A. enable the users to know better of science and technology .

    B. produce new electric products with a lower radiation value

    C. provide the public with less information on effective precaution

    D. inform the public about the potential risks with more patience

    65.   The word “ precaution” ( first appears in paragraph 1) in bold letters has the closets meaning to _______-

    A. introduction    B. intention   C. recommendation  D. prevetion

    66.  Which of the following might be the best title of the passage ?

    A. Science and Technology : A Double –edged Sword

    B. Technical Innovation : Worries and Information

    C. Science and Technology: Security Tips for Users

          Since the first Earth Day in 1970, Americans have gotten a lot “greener” toward the environment. “We didn’t know at that time that there even was an environmentlet alone that there was a problem with it.” says Bruce Andersonpresident of Earth Day USA.

          But what began as nothing important in public affairs has grown into a social movement. Business peoplepolitical leadersuniversity professorsand especially millions of grass­roots Americans are taking part in the movement. “The understanding has increased manymany times”says Gaylord Nelsonthe former governor from Wisconsinwho thought up the first Earth Day.

          According to US government reportsemissions(排放)from cars and trucks have dropped from 10.3 million tons a year to 5.5 million tons. The number of cities producing CO beyond the standard has been reduced from 40 to 9. Although serious problems still remain and need to be dealt withthe world is a safer and healthier place. A kind of “green thinking” has become part of practices.

          Great improvement has been achieved. In 1988 there were only 600 recycling programstoday in 1995 there are about 6,600. Advanced lightsmotorsand building designs have helped save a lot of energy and therefore prevented pollution.
          Twenty-­five years ago
    there were hardly any education programs for environment. Todayit’s hard to find a public schooluniversityor law school that does not have such a kind of program. “Until we do thatnothing else will change”says Bruce Anderson.

    27. According to Anderson, before 1970, Americans had little idea about    

    A. the social movement.                      B. environmental problems. 

    C.    recycling techniques.                D. the importance of Earth Day.

    28. Where doe the support for environmental protection mainly come from?

    A. The grass-roots level                         B. The business circle

    C. Government officials                         D. University professors

    29. What have Americans achieved in environmental protection?

    A. They have cut car emissions to the lowest.

    B. They have settled their environmental problems.

    C. They have reduced pollution through effective measures.

    D. They have lowered their CO levels in forty cities.

    In the 1500’s when the Spanish moved into what later was to become the southwestern United States, they came across the ancestors of the modern-day Pueblo, Hopi, and Zuni peoples. These ancestors, known variously as the basket makers, the Anasazi, or the Ancient ones, had lived in the area for at least 2,000 years. They were an advanced agricultural people who used irrigation to help grow their crops.

    The Anasazi lived in houses constructed of adobe (土砖) and wood. Anasazi houses were originally built in holes and were entered from the roof. But around the year 700 A.D., the Anasazi began to build their homes above ground and join them together into groups of multistoried large buildings, which the Spanish called pueblos or villages. Separate rooms under the ground in these pueblos – known as kivas – were set aside for religious ceremonies. Each kiva had a hole that was believed to lead to the underworld. The largest pueblos had five stories and more than 800 rooms.

    The Anasazi family was matrilinear (母系遗传). The holy objects of the family were under the control of the oldest female, but the actual ceremonies were conducted by her brother, or son. Women owned the rooms in the pueblo and the crops, once they were harvested. While still growing, crops belonged to the men, who, in contrast to most other Native American groups, planted them. The women made baskets and pottery; the men made cloth and jewelry.

    Each village had two chiefs. The village chief dealt with land disputes (争议) and religious affairs. The war chief led the men in fighting during occasional conflicts that broke out with neighboring villages and directed the men in community building projects. The solid political and social organization of the Anasazi made it almost impossible for other groups to conquer them.

    24. What do we know about the Anasazi people?

    A.  They were immigrants from Spain.    B.   They were good at growing crops.   

    C. They stored their crops in caves.              D. They had battles against the Spanish.

    25. What does the underlined word "they"(Paragraph 3) refer to?

    A. Women.         B. Pueblos.              C. Crops.   D. Rooms.   

    26. What can be concluded from the text?

       A.  The Anasazi benefited from trade with the Spanish.

    B.  The division of labor in Anasazi society was clear.

    C.  The Spanish caused harm to Anasazi society.

    D.  Constant conflicts existed in Anasazi society.

    27. What can best describe the Anasazi?

    A. Aggressive.           B. United.   C.  Honesty.    D. Selfish.

    Sleep deprivation(缺失)is an important hidden factor in lowering the achievement   of school pupils, according to researchers carrying out international education tests.

      It is a particular problem in richer countries with sleep experts linking it to the use of mobile phones and computers in bedroom late at night. Sleep deprivation is such a serious problem that lessons have to be dragged down to a lower level to suit sleep-deprived learners, the study found. The international comparison, carried out by Boston College, found the United States to have the highest number of sleep-deprived students, with 73% of 9- and 10-year-olds and 80% of 13- and 14-year-olds identified by their teachers as being negatively affected. In literacy(读写能力) tests there were 76% of 9- and 10-year-olds lacking sleep. This was much higher than the international average of 47% of primary pupils needing more sleep and 57% among the secondary age group.

      Other countries with the most sleep-deprived youngsters were New Zealand, Saudi Arabia, Australia, England, Ireland and France. High-performing Finland is also among the most lacking in sleep. Countries with the best records for getting enough

    sleep include Azerbaijan, Kazakhstan, Portugal, the Czech Republic, Japan and Malta. “I think we underestimate the impact of sleep. Our data show that across countries internationally, on average, children who have more sleep achieve higer in maths, science and reading. That is exactly what our data show,” says Chad Minnich of the TIMSS and PIRLS International Study Center.

      “It’s the same link for children who are lacking basic nutrition,” says Mr Minnich, based at the Lynch School of Education, Boston College. “If you are unable to concentrate, to attend mentally, you are unable to achieve at your best level, because your mind and body are in need of something more basic. Sleep is a fundamental need for all children. If teachers report such large proportions of children suffering from lack of sleep, it’s having a significant impact. But worse than that, teachers are having to adjust their instruction based on those children who are suffering from a lack of sleep. The children who are suffering from a lack of sleep are driving down instruction.”That means that even the children who are getting enough sleep are still suffering from this sleep-related lowering.

      24. What did the research of Boston College try to find

      A. Why children don’t get enough sleep    

      B. How many hours between sleep and test result

      C. The relationship between sleep and test results

      D. The relationship between sleep and health

      25. Many children suffer from sleep deprivation because _________.

      A. they sit in front of the TV for too long    

      B. they can hardly sleep soundly and deeply

      C. their homework occupies too much of their time 

      D. modern technological devices consume a lot of their time

    26. Which of the following countries has the most sleep-deprived students?

      A. Japan     B. Malta     C. Finland     D. Portugal

      27. Why are children who get enough sleep also victims?  

      A. Because they are disturbed by sleep-deprived students

    B. Because teaching is driven down by sleep-deprived students

      C. Because they have to spend time helping sleep-deprived students

      D. Because the teachers waste time disciplining sleep-deprived students

        Five meteorologists(气象学家) who were trapped for two weeks after polar bears surrounded their weather station are now able to leave after the creatures were chased away. Their supervisor told NBC News early Wednesday.

        Russian officials had feared the siege(围困) could last for another month, the time it would take to reach the islands in the Kara Sea, high in the Arctic Circle. But on Tuesday night a research ship took a detour(绕道) to assist those weathermen, station supervisor Vasily Shevchenko told NBC News. The ship run by Russia’s state-run oil firm Rosneft frightened away the bears using its helicopter, before resupplying the weather station with more food and puppies(幼犬). The puppies are not yet big enough to deter the bears, but the station is planning to draft in a replacement adult guard dog as soon as possible.

        Some of the bears had taken to sleeping directly outside the windows of remote outpost. There was no risk of the researchers starving because they had a year’s worth of food, but they were forced to take dangerous trips to a nearby building, holding a gun for protection, according to Shevchenko.

        Polar bears are an endangered species. In Russia, it’s a crime to shoot them unless in self-defense. The bears usually leave the islands in the summer, but this time they were trapped by the melting ice, an apparent sign of climate change, according to Shevchenko. “They’ve stayed on the island because there is nowhere for them to go,” he said.

        The animals suffer from global warming because it shrinks the floating ice that forms their main hunting ground. According to the environmental group the World Wide Fund for Nature, known as the WWF, this has got some polar bears to go near human habitats in search of food.

    13. What did the research ship do to help the five meteorologists?

    A. Drive them home.

    B. Shoot all the bears.

    C. Use its helicopter to scare the bears away.

    D. Supply the weather station with more money.

    14. What made the bears trapped on the island according to the text?

    A. Sea pollution.             B. Climate change.

    C. Humans’ hunting.          D. Animal’s hunting.

    15. What can we infer from the text?

    A. People in Russia can hunt bear for money.

    B. The melting ice will kill all the polar bears.

    C. The five meteorologists hated the bears very much.

    D. WWF made some contributions to protecting polar bears.

    School’s out. It’s been a long day, so you head home to relax. You’re greeted by a friend who’s happy to see you, listens to you talk about rest, tells you a new joke, helps you put away your school stuff (东西), and reminds you to text your cousin happy birthday. And that’s before he helps you with your homework.

    This is your future, and it all starts with a knee-high robot called NAO (pronounced NOW). It kind of looks like you, walks and dances, listens and talks, and even learns and thinks for itself. Its creators predict that the state-of-the-art robot could be a companion at home by the year 2040.

    This $16,000 robot recognizes human facial features, so it knows who you are. NAO can even express emotions. It represents the new generation of “autonomous” —or self-guided robots. These robots can sense, think, and act. Other robots might do two out of the three. For example, a robot might sense things using cameras and think using computers, but with no arms, wheels, or claws, it can’t act. Other robots can move and sense things, but can’t think for themselves. These aren’t self-guided robots. But NAO can do it all.

    “You can program your computer to give NAO what could be called personality,” says Natanel Dukan of Aldebaran Robotics, the French company that built NAO. The robot has cute, childlike features — a high voice, small body, big eyes, and a large head. “These are things that are known to have an emotional appeal to people,” robot expert Dan Kara says, “NAO’s friendly design helps in one of NAO’s main functions — to teach people how useful personal robots can be. Someday it may help you pass a test!”

    21. What do we know about NAO from the first two paragraphs?

    A. It is as tall as humans.                B. It is highly intelligent.

    C. It is widely used in schools now.        D. It is designed to help with the housework.

    22. The author develops the third paragraph mainly _____.

    A. by cause and effect   B. by order in time         C. by comparison          D. by process

    23. According to Dan Kara, NAO is _____.

    A. silent                        B. low-cost            C. lightweight               D. user-friendly

    24. The main purpose of the text is to _____.

    A. ask people to buy the robot          B. introduce a new kind of robot

    C. do an experiment about robots        D. compare different kinds of robots

    On April 14th, 2010, my entire life changed in an instant. One moment I was joyfully riding through the sunshine. The next moment, metal, flesh and bone were spreading against the pavement in a thunderous crash. Another cyclist, biking carelessly, had cut me off and sent me supermanning toward oncoming traffic.

    As if to symbolize the accident that had hit my life, another disaster also occurred on April 14th, 2010. It cost the airline industry l.7 billion. Ten million travelers were stuck for days. Economies all over the world were disturbed. This was the eruption of Eyjafjallajokull, one of Iceland’s many volcanoes.

    However, volcanoes are not all bad. In fact, they are necessary. They are responsible for the birth of new earth, and for the creation of rich soil. This eruption gave off 0.15 million tons of carbon dioxide into the atmosphere daily. But cancelling 48% of the worlds flight travel saved about 2.8 million tons of CO2 from entering the atmospheretemporarily decreasing our carbon footprint.

    Similarly, the accident had badly affected my emotion but it also allowed me to look more closely inside myself and discover things about myself I never would have realized. I learned how not to judge myself for my new limitations.

    In 1973, another Icelandic volcano, Eldfell, broke out. Icelanders decided to bomb it with cold water until it froze and chose a different path. After their plan workedthey used the geothermal (地热) energy for the next 15 years to heat their homes. A good example of life bringing lemons, and making lemonade! One must move on from misfortunes, focusing only on the present moment and being hopeful for the future.

    I ran from April 14th, 2010, to every kind of escape. Eventually I ended up in university for a new-found love in Earth sciences.

    32. What happened to the writer on April 14th, 2010?

    A. He was involved in a car crash.

    B. He was stuck in Iceland’s airport.

    C. He witnessed a volcanic eruption.

    D. He was badly injured on a bike ride.

    33. Which was an effect of the eruption of Eyjafjallajokull?

    A. Economy was cost globally by the eruption.

    B. Carbon dioxide was increased temporarily.

    C. The earth in Ireland was terribly polluted.

    D. Most of the world’s planes were held up.

    34. Why did the writer mention the Eldfell volcano?

    A. It broke out in Iceland on April 14th as well.

    B. It symbolized the accident that changed his life.

    C. It encouraged him to know more about himself.

    D. It told us to make the most of given situation.

    35. What is the best title for the passage?

     Nuclear energy is a controversial topic. There has been widespread public debate over it. It seems that the nuclear energy is either a gigantic disaster waiting to happen or the all-powerful way of the future.

    It is often believed that nuclear energy is something we cannot do without. We live in a consumer society with a huge demand for commercial products of all kinds. Besides, an increase in industrial production is considered to be one solution to the problem of mass unemployment. Such an increase assumes an abundant and cheap energy supply. Many people believe nuclear energy provides an endless and economical source of power and that it is therefore fundamental for an industrially developing society. Among other advantages is that nuclear power, except for accidents, is clean. A further advantage is that a nuclear power station can be run and maintained by relatively few technical and administrative staff. The nuclear reactor represents a great step in our scientific evolution and, whatever the anti-nuclear group says, it is wrong to expect a return to more primitive sources of fuel.

    However, opponents(people who oppose something)of nuclear energy point out that nuclear power stations bring a direct danger not only to the environment but also to civil liberties. Environmentalists argue in the long run nuclear energy wastes valuable resources and disturbs the ecology to an extent which could bring about the destruction of the human race. Furthermore, it is questionable whether nuclear power is a cheap source of energy when everything is considered. There have, for example, been very costly accidents in America, in Britain and, of course, in Russia. The possibility of increases in the cost of uranium(铀)in addition to the cost of greater safety provisions(设施)could price nuclear power out of the market.

    In spite of the case against nuclear energy above, nuclear energy programmes are expanding, which assumes a continual growth in industrial production and consumer demands. However, it is doubtful whether this growth will or can continue. Having weighed up the arguments in both sides, it seems that there are good economic and ecological reasons for sources of energy other than nuclear power.

    32.What’s the writer’s attitude toward nuclear energy?

        AObjective        B. Negative        C. Acceptable           D. Appreciative

    33.According to the opponents, which of the following is true of nuclear energy?

        AOriginal         BEndless          CCheap            DUnsafe

    34.Some people believe that nuclear energy is the most important because         .

        Aunclear power stations can be run and maintained by relatively few staff

        Bit can meet the growing demand of an industrially developing society

        Cit represents a huge step forward in our scientific evolution

        Dit provides a perfect way out to increase employment

    They say necessity is the mother of invention. While that might not be the case for every invention, most of coolest inventions are definitely useful.

    The levitating Lightbulb

    The US artist and scientist Simon Morris got the idea of making lightbulb float from hoverboards(悬浮滑板). But the floating is not the most amazing part. It was done simply by putting magnets in the bottom of the bulb and in the wooden base. The rejection force between the opposite ends of the magnets does the job.

    What’s new here is a technology called induction(电磁感应). It allows the ligtbulb to get power from the base even when they aren’t in contact.

    Shoes that tie themselves

    They’re not what you think-shoelaces that tie themselves in the way we tie them. Instead, the new shoes have small motors that control their laces. When you step in them, your feet will hit a sensor in the shoes and the motor will automatically tighten the laces. There are also two buttons on side of the shoes to tighten and loosen them so you can control the laces by yourself. They could actually give athletes an advantage during competitions. They are also useful for people who cannot move their arms or fingers easily.

    The no-touch thermometer

    Maybe, it’s an impossible task for little kids putting a thermometer in their armpits and staying still for minutes.

    Now, using infrared(红外线) technologyscientists have invented thermometers that take the body’s temperature without contacting the body. Users can simply put the thermometer 2.5 centimeters form a patient’s forehead and press the button, and it can get the reading in two seconds.

    Not touching the body also means cleaner processes, since patients needn’t worry about whether someone else has used the thermometer before.

    24. Which of the following about the levitating Lightbulb is true?

      A. It runs only by contacting the base.

      B. It gets power by floating from hoverboards.

      C. It works by the rejection force from magnets.

      D. It operates by using infrared technology.

    25. Who do you think possibly use self-tying shoes?
