           Scientists are debating how to limit their newly-discovered power to change genetic structure. Scientists already modify the genes of farm animals and agricultural plants to make them more productive or stronger. But now they can also change genes in wild animals and plants. These genes would continue into later generations. For example, it may be possible for scientists to remove from existence the kind of mosquitoes that carry the Zika virus. They might also be able to permanently remove species of plants and animals that are destructive to other species.

           In a report published last week, the U.S.National Academies of Sciences, Engineering and Medicine (NAS) said it supports continued research on this kind of gene control. But it warned that it is not possible to know what will happen when these changed plants and animals are released into the wild.

           Sixteen biologists, ethicists(伦理学家) and policymakers are on an NAS committee that is examining the issue. They say that there is value to the new technology. But, they say, there is not enough evidence to support the release of modified organisms (生物体) from the laboratory into nature.

           Many people would support stopping mosquitoes and rats from carrying diseases. But scientists say we must understand the possible scientific, ethical, legal and social results of such action before we decide whether to take it. Gene modification is spread through reproduction(繁殖).

           Changed genes will continue to spread as long as an animal or plant continues to reproduce. They cannot be limited to a farm or kept within a country’s borders. Scientists are wondering what may happen if a modified organism mates with another species. They are not yet sure how the modified genes would affect the other species. It is possible that those genes could harm those creatures or even lead to their disappearance from our planet.

    32.What possible advantage does gene control in wild animals and plants have?

        A. Making all the species more productive and stronger.

        B. Changing the Zika virus permanently.

           C. Removing the destructive species forever.

           D. Having changed genes in their next generations.

    33Which of the following is NOT true according to the passage?

           A. Scientists are not sure what exact results gene modification leads to.

           B. Scientists won’t modify any genes before they make the final decision.

           C. Gene modification has benefited some farm animals and agricultural plants.

           D. Scientists have not applied gene modification to wild animals and plants in case of possible danger.

    34. What can be the best title for the passage?

           A. Stop research on gene control

           B. Power and danger of gene control

           C. How to change genetic structure

           D. Advantages of gene control in wild animals and plants

    35. As for genetically changed wild animals and plants , what are scientists worried about?

    A. Their genes may spread to later generations.

    B. They may be more productive.

    C. They may cause damage to their living habitat.

    D. They may become weaker or die out.

    The best way to invent something profitable is to note all the problems people currently face. Once your invention succeeds in reducing the number of problems that people face, you are sure to get the desired appreciation, thus making the invention highly profitable.

    Almost every company is in the race of attempting to solve people's problems. As a result, many great inventions appear so that people cannot help but buy something to simplify just a small part of their life. Therefore, it is very important for you to come up with a highly competitive invention. For instance, people these days are in search of household appliances (装置) that consume the least amount of electricity. You can try inventing an appliance that consumes less electricity compared to the appliances produced by other companies.

    In order to make sure that your invention works effectively, you first need to try it out for yourself. A non-experimented product may fail to gain the trust of people. Experimenting on the product will also help you remove errors, if any, before bringing it to the marketplace. Moreover, you may come across an area that needs some improvement. However, coming up with an invention completely depends on your personal areas of interest. If you try inventing something that is actually not a part of your interest, you will not have the necessary passion to perfect the idea.

    Successful invention ideas come from the identification of a common need and then try to fill the need by finding a workable solution. In fact, inventing something requires an inventor to devote much time and effort; therefore it is important for you to keep patient throughout the procedure. And the only thing that tells apart an ordinary person from a successful inventor is the different way of thinking. Once you get an idea about what you actually want to invent, you can then get started by adding in your own creativity in various areas of the invention.

    51. When you want to invent something, you should first consider whether it can_____.

      A. make people’s life easy                 B. bring you a high profit or not

      C. be popular with all people                    D. work effectively without errors

    52. By mentioning the household appliance in the 2nd paragraph, the author implies that_____.

      A. an ideal invention should be a household appliance

      B. it is appropriate for people to have a low-carbon lifestyle

      C. your intended invention should be better than other products

      D. there're fierce competitions between household appliances

    53. The author's suggestions are mentioned in the passage EXCEPT _____.

      A. noting people's problems to find invention ideas

      B. trying out the product before it reaches the market

      C. making inventions based on your own interest

      D. perfecting your idea before you start your invention

    54. In the author's opinion, what makes an inventor different from average people?

      A. The personal interest.              B. The way of thinking.

      C. The extra patience.                         D. The whole devotion.

    55. What does the text mainly talk about?

      A. An invention without enough experi­ments will surely fail.

      B. A successful invention is largely based on people's needs.

      C. An inventor's passion matters much more than his creativity.

      D. A highly profitable invention will always have no errors.

    The recovery of trade following the Middle Ages in Europe resulted in a demand for goods from Asia. Trade routes were established across the Mediterranean and through the Middle East to handle this need. But, when the expansion of the Ottoman Empire caused destruction along these routes, Europeans were forced to seek alternative ways of importing these goods.

    In the early 1400s, Europeans began exploring the west coast of Africa in search of an all water route to Asia. These early explorations were led by the Portuguese. In1488, Bartholomeu Dias rounded the Cape of Good Hope(好望角) at the southern tip of Africa. In 1498, Vasco Da Gama established an all water route to India. The success of these explorations led Spain to begin its own voyages. In 1492, Christopher Columbus crossed the Atlantic Ocean and discovered the Americas for Spain. In 1519, supported by Spain, Ferdinand Magellan started on a voyage westward. He found a southern route around South America and came to the Pacific Ocean. Sailing west, he landed in the Philippine Islands, where he was killed in a fight with the people there. These discoveries had a lasting impact on Europe, Asia, Africa and the Americas.

    European nations competed for colonies across the globe. These colonies were exploited for their raw materials, and used as new markets for European goods. Europeans had little regard for most of the native peoples of these areas, and as a result, there was a great loss of life and culture.

    The Age of Exploration is a turning point in history because it changed the way people lived across the world. The biggest aspect of this change deals with the exchange of people, plants, animals, ideas and technology. This is known as the Columbian Exchange, because it starts with Columbus. While many aspects of this exchange had positive effects, such as the exchange of foods between Europe and America, there were also negative effects, such as the exchange of diseases between Europe and America.

    Access to new and better foods allowed the European population to grow, and access to the New World gave these people a place to go. New World civilizations such as the Inca and Aztecs faced near total destruction of their cultures either through disease brought by the Europeans or by colonization. Africa faced a forced movement of its people, as slaves became the main labor force in the Americas. The Age of Exploration was both a positive and negative experience for many civilizations.

    46. Why did Europeans search for new trade routes to Asia?

    A. Asia was a main trade centre at that time.

    B. Europeans needed new cultural activities.

    C. The original routes were broken down by an empire.    

    D. The expansion of Ottoman Empire needed more goods.

    47. In the 15th century, sailors supported by Spain______.
     A. sailed across the Atlantic Ocean                     

     B. found an all water route to India
     C. sailed around the Cape of Good Hope            

     D. found a southern route to the Pacific Ocean

    48. As a result of Columbian Exchange, ______.

        A. Africans got new and better foods                   

     B. the European population began to decrease
     C. some diseases spread among more countries

     D. New World civilizations developed more quickly

    49. What impact did the European exploration have on Africa?

     A. Its economy grew rapidly.

     B. Its culture was totally destroyed.

     C. There was a huge increase in the African population.

     D. Millions of Africans were brought to the Americas as slaves.

    50. What can be the best title for the text?

         A. The New World                            B. The Age of Exploration
         C. The Columbian Exchange            D. Great European Navigators(
    航海家)

           Cancer is a terrible disease. Every year in the UK, more than 330,000 people get cancer, and doctors usually use a kind of therapy called radiotherapy to treat people. This treatment uses high energy X-rays to destroy the disease, but the effects of treatment can be nearly as bad as the cancer. As the X-rays destroy the cancer cells, they also damage healthy cells that are next to them. It’s like using a shotgun to kill an insect. When really important parts of a person’s body are hurt by the X-ray energy, it can have very bad results. It can also make more cancer grow in the damaged places in the future.

          A new therapy that uses protons(质子) instead of X-ray energy could be the answer to the problem. In a project called PRaVDA, scientists from the UK and South Africa are working to this. If X-ray energy is like a shotgun, then protons can work more like a laser. Scientists can make protons travel through someone’s body without hurting them, and only damage the cancer.

    The PRaVDA scientists use computers to make a 3-D model of the cancer cells to make sure the protons go to the right places. “It’s more accurate,” said Michaela Esposito, PhD, from the University of Lincoln.

          Building this technology was very difficult, though. Professor Nigel Allinson from the University of Lincoln, the project leader, has put together a team of many different kinds of scientists with different skills. Those skills were all needed to make what he calls “one of the most complex” medical machines ever. It’s also 10 times more expensive than X-ray radiotherapy. Even so, Allinson believes that most cancer treatment will be done by protons in the future. “I think it will improve the quality of life of many cancer patients,” he says.

    28What point does the first paragraph make?

       A. Cancer is a really terrible disease. 

       B. Lots of people get cancer every year in the UK.

       C. Radiotherapy isn’t a perfect way to cure cancer.

       D. Radiotherapy is a commonly used therapy against cancer.

    29 What can be concluded about the new therapy?

       A. It’s much cheaper than X-ray radiotherapy.

       B. It depends on protons to locate the cancer cells.

       C. Damaging the cancer by replacing X-rays with lasers is much more accurate.

       D. It uses protons to damage the cancer cells without damaging healthy cells.

    30According to Professor Allinson, the new therapy         .

       A. will enable cancer patients to enjoy a better life

       B. will cure most cancers in the future

       C. will ensure that cancer patients live longer

       D. will replace radiotherapy completely

    31 What can be inferred from the text?

       A. Science and technology are a double-edged sword.

       B. Not every cancer patient will be able to afford proton therapy.

       C. Radiotherapy is completely the wrong way to cure cancer.

       D. The complex medical machine mentioned will soon be put into use.

    Do you know how it is when you see someone yawn and you start yawning too? Or how hard it is to be among people laughing and not laugh yourself? Well, apparently it's because we have mirror neurons (神经元)in our brains.
         Put simply, the existence of mirror neurons suggests that every time we see someone else do something, our brains imitate (
    模仿)it, whether or not we actually perform the same action. This explains a great deal about how we learn to smile, talk, walk, dance or play sports. But the idea goes further: mirror neurons not only appear to explain physical actionsthey also tell us that there is a biological basis for the way we understand other people.
         Mirror neurons can undoubtedly be found all over our brains
    but especially in the areas which relate to our ability to use languagesand to understand how other people feel. Researchers have found that mirror neurons relate strongly to language. A group of researchers discovered that if they gave people sentences to listen to (for example: "The hand took hold of the ball"), the same mirror neurons were triggered as when the action was actually performed (in this example, actually taking hold of a ball).
        Any problems with mirror neurons may well result in problems with behavior. Much research suggests that people with social and behavioral problems have mirror neurons which are not fully functioning. However, it is not yet known exactly how these discoveries might help find treatments for social disorders.
         Research into mirror neurons seems to provide us with even more information concerning how humans behave and interact(
    互动).Indeed, it may turn out to be the equivalent (相等物)for neuroscience of what Einstein's theory of relativity was for physics. And the next time you feel the urge to cough in the cinema when someone else does—well, perhaps you'll understand why.

    42. Mirror neurons can explain _____.

    A. why we cry when we are hurt  

    B. why we cough when we suffer from a cold

    C. why we smile when we see someone else smile 

    D. why we yawn when we see someone else stay up late
    43.The underlined word "triggered" in the third paragraph probably means “____”.
        A. set off      B. cut off      C. built up         D. broken up
    44.We can learn from the passage that mirror neurons _____.
        A. relate to human behavior and interaction  
        B. control human physical actions and feelings
        C. result in bad behavior and social disorders  
        D. determine our knowledge and language abilities
    45. What is the passage mainly about?
        A. Ways to find mirror neurons.         B. Problems of mirror neurons.
        C. Existence of mirror neurons.         D. Functions of mirror neurons.

    Shyness is the cause of much unhappiness for a great many people. Shy people are anxious and self-conscious; that is, they are concerned with their own appearance and actions too much. Negative thoughts are constantly occurring in their minds: What kind of impression am I making? Do they like me? Do I sound stupid? Am I wearing unattractive clothes?

    It is obvious that such uncomfortable feelings must affect people unfavorably. A person's self-concept is reflected in the way he or she behaves and the way a person behaves affects other people's reactions. In general, the way people think about themselves has a deep effect on all areas of their lives.

    Shy people, who have low respect, are likely to be passive and easily influenced by others. They need faith that they are doing "the right thing". Shy people are very sensitive to criticism. It makes them feel inferior(自卑). They also find it difficult to be pleased by praises because they believe they are unworthy of praise. A shy person may respond to a praise with a statement like this one: "You're just saying that to make me feel good, I know it's not true.” It is clear that, while self-awareness is a healthy quality, overdoing it is harmful.

    Can shyness be completely got rid of, or at least reduced? Fortunately, people can overcome shyness with determination since shyness goes hand in hand with lack of self respect. It is important for people to accept their weakness as well as their strengths. Each one of us has his or her own characteristics. We are interested in our own personal ways. The better we understand ourselves, the easier it becomes to live up to our chances for a rich and successful life.

    29. The first paragraph is mainly about______.

    A. the effect of shyness on people     B. the cause of shyness

    C. the feelings of shy people         D. the questions in the minds of shy people

    30. According to the writer, self-awareness is______.

    A. harmful to people          B. a healthy quality

    C. the cause of unhappiness    D. a weak point of shy people

    31. The underlined word “it” in Paragraph 3 refers to_____.

       A. shyness     B. criticism    C. sensibility   D. praise

    32. We can learn from the passage that shyness can ______.

    A. have nothing to do with lack of self respect

    B. help us to live up to our full development

    C. enable us to understand ourselves better

    Daniel Anderson, a famous psychologist, believes it’s important to distinguish television’s influences on children from those of the family. We tend to blame TV, he says, for problems it doesn’t really cause, overlooking our own roles in shaping children’s minds.

    One traditional belief about television is that it reduces a child’s ability to think and to understand the world. While watching TV, children do not merely absorb words and images (影像). Instead, they learn both explicit(表面的) and hidden meanings from what they see. Actually, children learn early the psychology of characters in TV shows. Furthermore, as many teachers agree, children understand far more when parents watch TV with them, explaining new words and ideas. Yet, most parents use an educational program as a chance to park their kids in front of the set and do something in another room.

    Another argument against television is that it replaces reading as a form of entertainment. But according to Anderson, the amount of time spent watching television is not related to reading ability. TV doesn’t take the place of reading for most children; it takes the place of similar sorts of recreation, such as listening to the radio and playing sports. Things like parents’ educational background have a stronger influence on a child’s reading. “A child’s reading ability is best predicted by how much a parent reads.” Anderson says.

    Traditional wisdom also has it that heavy television-watching lowers IQ scores and affects school performance. But here, too, Anderson notes that no studies have proved it. In fact, research suggests that it’s the other way around. “If you’re smart young, you’ll watch less TV when you’re older,” Anderson says. Yet, people of lower IQ tend to be lifelong television viewers.

    For years researchers have attempted to show that television is dangerous to children. However, by showing that television promotes none of the dangerous effects as conventionally (传统地)believed, Anderson suggests that television cannot be condemned(谴责) without considering other influences.

    32. An educational program is best watched by a child _________.

    A. on his own                                                  B. with other kids

    C. with his parents                                           D. with his teachers

    33. Which of the following is most related to children’s reading ability?

    A. Radio-listening                                             B. Television-watching

    C. Parents’ reading list                                      D. Parents’ reading background

    34. Anderson believed that _________.

    A. the more a child watches TV, the smarter he is

    B. the younger a child is, the more he watches TV

    C. the smarter a child is, the less likely he gets addicted to TV

    D. the less a child watches TV, the better he performs at school

    35. What is the main purpose of the passage?

    A. To advise on the educational use of TV.          B. To describe TV’s harmful effects on children.

    C. To explain traditional views on TV influences. D. To present Anderson’s unconventional ideas.

    Scientists today are making greater effort to study ocean currents (洋流) . Most do it using satellites and other high-tech equipment. However, ocean expert Curtis Ebbesmeyer does it in a special way — by studying movements of random floating garbage. A scientist with many years’ experience, he started this type of research in the early 1990s when he heard about hundreds of athletic shoes washing up on the shores of the northwest coast of the United States. There were so many shoes that people were setting up swap meets to try and match left and right shoes to sell or wear.

    Ebbesmeyer found out in his researches that the shoes — about 60,000 in total — fell into the ocean in a shipping accident. He phoned the shoe company and asked if they wanted the shoes back. As expected, the company told him that they didn’t. Ebbesmeyer realized this could be a great experiment. If he learned when and where the shoes went into the water and tracked where they landed, he could learn a lot about the patterns of ocean currents.

    The Pacific Northwest is one of the world’s best areas for beachcombing(海滩搜寻) because winds and currents join here, and as a result, there is a group of serious beachcombers in the area. Ebbesmeyer got to know a lot of them and asked for their help in collecting information about where the shoes landed. In a year he collected reliable information on 1,600 shoes. With this data, he and a colleague were able to test and improve a computer program designed to model ocean currents, and publish the findings of their study.

    As the result of his work, Ebbesmeyer has become known as the scientist to call with questions about any unusual objects found floating in the ocean. He has even started an association of beachcombers and ocean experts, with 500 subscribers from West Africa to New Zealand. They have recorded all lost objects ranging from potatoes to golf gloves.

    73. The underlined phrase swap meets in Paragraph 1 is closest in meaning to _____.

    A. fitting rooms            B. trading fairs             C. business talks          D. group meetings

    74. We can infer from the passage that Ebbesmeyer phoned the shoe company to find out _______.

    A. what caused the shipping accident                    

    B. when and where the shoes were found

    C. whether it was all right to use their shoes                  

    D. how much they lost in the shipping accident

    75. How did Ebbesmeyer prove his assumption (假定,设想)?

    A. By collecting information from beachcombers.

    B. By studying the shoes found by beachcomber.

    C. By searching the web for ocean currents models.

    D. By researching ocean currents data in the library.

    76. Ebbesmeyer is most famous for _______.

    A. traveling widely the coastal cities of the world

    B. making records for any lost objects on the sea

    C. running a global currents research association

    D. phoning about any doubtful objects on the sea

    77. What is the purpose of the author in writing this passage?

    A. To call people’s attention to ocean pollution.

    B. To warn people of shipping safety in the ocean.

    C. To explain a unique way of studying ocean currents.

    D. To give tips on how to search for lost objects on the beach.

    Walk into the small Australian town of Coober Pedy on any given day, and you will get the strange feeling of an abandoned ghost town. So why even call it a town? Because that’s exactly what it is, complete with 4,000 plus residents of 48 nationalities, all of whom live underground!

    Located about 846 kilometers north of Adelaide, Coober Pedy was built in 1915, following the discovery of opal(猫眼石). As people from across the country and world flocked to mine the precious stone, they realized that while working under the ground was easy, living above it was not, thanks to the extreme temperatures.

    They therefore did what humans do best when faced with a situation they cannot changeadaptation! In this case, it meant living underground, by changing old mines into homes and building the world’s first and most likely, the only underground town.

    As years have gone by, the homes have become bigger and more complex. There are now also several hotels and inns to accommodate the tourists that flock in from all over the world to see this unusual town.

    Recently there was a major discovery in the scientific research—the mapping of all DNA in a human gene(基因) is completeCouple of years ago, this seems an impossible task for scientist to accomplishAll this progress in science leads us to believe that the day, when the human being will be cloned, is not far awayHuman cloning has always been a topic of argument, in terms of morality or religion

    Taking a look at why cloning might be beneficial, among many cases, it is arguable that parents who are known to be at risk of passing a genetic limitation to a child could make use of cloningIf the clone was free of genetic limitationsthen the other clone would be as wellThe latter could foe inserted in the woman and allowed to ripen to termMoreover, cloning would enable women, who can't get pregnant, to have children of their own

    Cloning humans would also mean that organs could be cloned, so it would be a source of perfect transfer organsThis, surely would be greatly beneficial to millions of unfortunate people around the world that are expected to lose their lives due to failure of single (or more) organ(s). It is also arguable that a ban on cloning may be unlawful and would rob people of the right to reproduce and limit the freedom of scientists

    Arguments against cloning are also on a perfectly practical sidePrimarily, I believe that cloning would step in the normal "cycle" of lifeThere would be a large number of same genes, which reduce the chances of improvement, and, in turn, development—the fundamental reason how living things naturally adapt to the ever-changing environmentLife processes failing to do so might result in untimely disappearanceFurthermore, cloning would make the uniqueness that each one of us possesses disappearThus, leading to creation of genetically engineered groups of people for specific purposes and, chances are, that those individuals would be regarded as "objects" rather than people in the society

    Scientists haven't 100 percent guaranteed that the first cloned humans will be normalThus this could result in introduction of additional limitations in the human "gene-pool"

    Regarding such arguable topics in "black or white" approach seems very innocent to me personally. We should rather try to look at all "shades" of itI believe that cloning is only legal if its purpose is for cloning organs; not humansThen we could regard this as for "saving life" instead of "creating life"I believe cloning humans is morally and socially unacceptable

    32Which of the following is true according to the passage?

           AGenetic limitation will be beneficial for some women

           BA large number of genes will prevent us from developing

           CProhibition of cloning might limit the freedom of scientists

           DFirst cloned humans might be normal according to scientists

    33What's the author's opinion on cloning?

           ACloning should be entirely banned

           BCloning should be used in creating life

           CCloning will take away the right to reproduce

           DCloning is acceptable if it is used for cloning organs

    34Where can you read this article?

           AIn a story book         BIn a magazine

           CIn a science fiction      DIn a brochure

    35Which of the following shows the structure of the passage?

       Noise is one of the problems that have come with industrial advancement and progress in urban environments. It has significantly increased with the invasion (侵入)of social media websites and modern technology in homes , streets, schools and the workplace.

      While many people are unaware of the effects of noise pollution,experts say there are many psychological, health and mental effects of noise on human beings. Dr Maher Yaqoub, ear, nose and throat specialist, said, “When we go home to relax, we hear noise coming from modern devices such as smart phones and tablets that exist in nearly all houses. At the workplace, we hear noise produced by devices used at the workplace. On the way home, we are affected by the car horns and the like. All these sources of noise can have negative effects on human beings.”

      Recent studies on the issue have shown that many people suffer from increasing hearing loss due to exposure to constant noise. Infants and the elderly are more easily affected by noise –related damage than others. “In fact , noise can destroy a child’s hearing ability and have impact on his health as well,” Yaqoub said.

      Dr Alaa AL-Tabee, psychological and neurological (神经学的)disease specialist, said noise has negative impact on the psychological and health conditions of humans. It influences their performance at work or school as well as the way they communicate with others. Being exposed long to noise affects nerves and makes one feel dissatisfied and frightened because it harms the brain and reduces its activity. The end result is always discomfort and confusion.

      Noise can cause mental stress and leave the mind unable to understand and process information. A person’s level of alertness and ability to calculate are influenced as well. Sensitive children feel frightened if exposed to too much noise and such a feeling may get worse in the future and lead to depression, exhaustion and anxiety.

    32.From Dr Maher Yaqoub’s words ,we can learn that _____.

    A.     our home is not a place to relax any longer

    B.     the modern devices should be improved

    C.     human health is going from bad to worse

    D.    noise pollution exists everywhere

    33.When it comes to noise pollution, ____.

    A.     the majority can tell what bad effect it has

    B.     it has caused mental problems to most people

    C.     it is more necessary to protect the young and the old

    D.    it has made most people lose their hearing in a way

    34.If a person is exposed to constant noises, _____.

    A.     he will lose his ability to speak and hear

    B.     he perhaps will be in a poor mood

    C.     he is sure to have a poor relationship with others

    D.    he will become more sensitive and stressed

    35.What does the author mainly discuss in the text?

    A.     Noise pollution is destroying calmness of nature.

    B.     Human beings are being threatened by pollution.

    C.     Advanced technology is doing harm to humans

    D.    Our living environment is being seriously polluted

    A small robot may help children who are recovering from a long-term illnesses in the hospital or at home.

    These children may feel isolated from their friends and classmates. The robot takes their place at school. Through the robot, the children can hear their teachers and friends. They also can take part in class from wherever they are recovering.

    A Norwegian company called No Isolation created a robot. The co-founders of No Isolation are Karen Dolva and Marius Aabel. The robot is called AV1. AV1 goes to school for a child who is at home while recovering from a long-term illness. And the child’s school friends must help. They carry the robot between classes and place the robot on the child’s desk.

    Dolva explains how the robot AV1 works. She says, from home, the child uses a tablet or phone to start the robot. Then they use the same device to control the robot’s movements. At school, the robot becomes the eyes, ears and voice of the child. The child can take part in classroom activities from wherever she/he is recovering—whether at home or from a hospital bed. The robot is equipped with speakers, microphones and cameras make communicating easy. It was designed to be tough. It is water resistant and can take a fall from a desk without damage.

    Inside AV1, there is a small computer connected to a 4G network. A small camera hooked up to a small computer could do the job. But that would not be the same. AV1 is large and looks like a human for a reason. Dolva says this is important because the robot is supposed to be a friend to the children.

    And robots are, quite simply, cool. The robot just became available to the public. Hopefully AV1 will help some children feel less lonely while they are absent from class.

    25. Which of the following can replace the underlined word “isolated” in Paragraph 2?

    A. freed    B. tired     C. banned      D. separated

    26. What can we know about AV1?

    A. It can go to school on its own.    B. It is small and looks like a kid.

    C. It can replace children to attend classes.     D. It was created by Dolva and Aabel.

    27. How are the movements of AV1 controlled?

    A. By using a tablet or phone.    B. By joining in classroom activities.

    C. Through a small speaker.      D. Through a small camera.

    28. Who is AV1 mainly designed for?

    A. Children who have just recovered from illnesses.

    B. Children who can’t go to school for a long time.

    C. Children who are bored with going to school.

    D. Children who can’t see, hear or speak.

      Well, it’s time for Words and Their Stories. We present more expressions about food from Elnir Scardueli, a listener in Brazil.

       My mother believes you are what you eat. Then she’d always give us nutritious food. She likes serving us meat and potatoes, which can also mean the most important part of something. Here’s another expression about meat: one man’s meat is another man’s poison—one might like something very much while another person might hate it.

    My father’s a good and honest person. People say he’s the salt of the earth. He’d never pour salt on a wound, or make someone feel worse about something. However, sometimes he tells us a story that seems bigger than life. So we have to take it with a grain of salt.

    My husband makes enough money to support our family. So we say he brings home the bacon. He can cut the mustard(芥末), or do what is expected of him at work. Besides, he stands almost two meters tall, so it’s easy to find my husband in a crowd. He is a tall drink of water.

    I take the train to work. It is not a pleasant ride because the train is so crowded that we are packed like sardines(沙丁鱼).

    When we fail to see problems at work, my boss tells us to wake up and smell the coffee. We need to pay more attention and fix the problem.

    I once made a big mistake at the office and felt foolish. I had egg on my face.

    Over the weekend, my friend invited me to watch a football game on television. But I do not like football. It is not my cup of tea.

    We hope this has given you food for thought and stay with us next time. Thank you.

    Alexandra Scott was born to Liz and Jay Scott in Manchester, Connecticut on January 18, 1996, the second of four children. Shortly before her first birthday, Alex was diagnosed with neuroblastoma, a type of childhood cancer.

    On her first birthday, the doctors informed Alex’s parents that if she beat her cancer it was doubtful that she would ever walk again. Just two weeks later, Alex slightly moved her leg at her parents’ request to kick. This was the first indication that she would turn out to be a courageous and confident child with big dreams and big accomplishments.

    Scientists claim to have developed a revolutionary new giant 3D concrete printer that can build a 2,500-square-foot house in just 24 hours.

    The 3D printer, developed by Professor Behrokh Khoshnevis from the University of Southern California, could be used to build a whole house, layer by layer, in a single day.

    "It is basically scaling up 3D printing to the scale of building," said Khoshnevis.

    The giant robot replaces construction workers with a nozzle (喷嘴), which can quickly build a home based on a computer pattern, MSN News reported.

    Contour Crafting, as it is named, is a layered fabrication (构造) technology. Using this process, a single house or a colony of houses, each with possibly a different design, may be constructed in a single run, embedded (嵌入) in each house all the wires and pipes for electrical, plumbing and air-conditioning.

    The potential applications of this technology are far-reaching including in emergency, low-income, and commercial housing.

    "Our research also addresses the application of Contour Crafting in building habitats on other planets. Contour Crafting will most probably be one of the very few feasible approaches for building structures on other planets, such as the Moon and Mars, which are being targeted for human habitation before the end of the new century," researchers said on the project website.

    The technology may potentially reduce energy use and emissions. And the main advantages of the Contour Crafting process over existing technologies are the superior surface finish that is realized and the greatly increased speed of construction.

    8. Professor Khoshnevis has recently developed a 3D printer that can ________.

       A. build a 2500-square-foot house in a single day.

       B. construct a skyscraper, layer by layer.

       C. design a group of houses automatically.

       D. assist construction workers in their work.

    9. The new 3D printer uses the following to build a house EXCEPT ________.

       A. a nozzle        B. a computer pattern      C. a robot       D. an air-conditioner

    10. According to the text, the potential applications of Contour Crafting include building _______.

       A. emergency vehicles             B. low-income housing

       C. commercial centers             D. space stations on other planets

    11. What advantages of this new technology is mentioned in the text?

       A. It creates more jobs.             B. It is less time-consuming.

       C. It saves the building cost.         D. It emits no carbon dioxide.

    Surviving Hurricane Sandy (飓风桑迪)

    Natalie Doan, 14, has always felt lucky to live in Rockaway, New York. Living just a few blocks from the beach, Natalie can see the ocean and hear the waves from her house. “It's the ocean that makes Rockaway so special,” she says.

    On October 29, 2012, that ocean turned violent. That night, Hurricane Sandy attacked the East Coast, and Rockaway was hit especially hard. Fortunately, Natalie's family escaped to Brooklyn shortly before the city's bridges closed.

    In the following few days, the men and women helping Rockaway recover inspired Natalie. Volunteers came with carloads of donated clothing and toys. Neighbors devoted their spare time to helping others rebuild. Teenagers climbed dozens of flights of stairs to deliver water and food to elderly people trapped in powerless high­rise buildings.

    “My mom tells me that I can't control what happens to me”Natalie says, “but I can always choose how I deal with it.”

    Natalie's choice was to help.

Natalie also worked with other organizations to bring much­needed supplies to Rockaway. Her efforts made her a famous person .Last April, she was invited to the White House and honored as a Hurricane Sandy Champion of Change.

    Today, the scars(创痕) of destruction are still seen in Rockawaybut hope is in the air. The streets are clearand many homes have been rebuilt. “I can't imagine living anywhere but Rockaway,”Natalie declares.“My neighborhood will be back, even stronger than before.”

    24. When Natalie returned to Rockaway after the hurricane, she found ________.

    A. some friends had lost their lives

    B. her neighborhood was destroyed

    C. her school had moved to Brooklyn

    D. the elderly were free from suffering
