You are only as old as you feelit is saidBut soon scientists will be able to calculate

your real” physiological(生理的)age”

    Researchers studying genes believe they can calculate exact physiological age by looking at a number of clues in DNAThey don’t have to ask people how they feel or look at their appearance

    The breakthrough could solve the mystery of why some 70-year-olds function at the level of those in their 50swhile others become frail(虚弱的)sooner than you would think

    The researchers made the breakthrough by finding the“biomarkers”of aging in tiny worms(虫子).

    The worms they studied had all average lifespan(寿命)of three weeksHumans’ some remain live much longer than other similarly-aged wormswhile others show signs of premature aging

    By genetically profiling(基因识别)104 different worms at various agesthe researchers found a group of genes that are involved in the aging process

    “This is a first step ;our results were not perfectbut we were able to predict the ages of the animals 70 percent of the timewhich is far better than anything that has been done before”said Sireon Melov the lead researcher at Buck Institute for Age Research in California.

Now they want to extend their studies to mice and eventually humans

    “I am confident that at some point there will be a non-subjective(主观的)method of determining how old someone is with a high level of confidence”said Melov

    The speed at which people age depends on a number of things including genetic inheritance(遗传),lifestyle and mental health

    Determining chronological(按时间顺序的)age in both worms and humans is easy-count forward from birthBut determing physiological age has remained subjectivebased on how someone looks or functions

    The findings have special meanings for age research in humansExamining biomarker over time would provide a scientific basis for anti—aging medicinesThe technology would also provide a means of determining whether a person is aging faster or slower than people would normally think

1The passage mainly talks about           

Athe new finding of gene studying

Bthe relationship between genes and the age

Cthe breakthrough in mental health

Dbiomarkers of aging, in tiny worms

2The researchers’ next goal is to study        

Atiny worms              Bbiomarkers           Chumans           Dmice

3Which of the following statements is TRUE?

   AThe researchers have found biomarkers of ageing in humans

   BThe researchers are able to predict the ages of the humans 70 percent of the time

   CPeople’s aging depends oil genetic inheritancelifestyle and mental healthetc

   DThere will be a simple method of determining how old someone is

4In the futurescientists will ____          

   Aproduce effective anti-ageing medicines

   Bfind a group of genes that are involved in the ageing process

   Cdetermine physiological age subjectively

   Dset up an institute to calculate humans’ real age

Dirty Britain

Before the grass has thickened on the roadside and leaves have started growing on the trees is a perfect time to look around and see just how dirty Britain has become. The pavements are stained with chewing gum that has been spat out and the guttersthe low part at the edge of a road where water collects and flows away: are full of thrown away fast food cartons. Years ago I remember traveling abroad and being saddened by the plastic bags, waste bottles at the edge of every road. Nowadays, Britain seems to look at least as bad. What has gone wrong?

   The problem is that the rubbish created by our increasingly mobile lives lasts a lot longer than before. If it is not cleared up and properly thrown away, it stays in the bushes for years; a

semi-permanent reminder of what a shabby little country we have now. Firstly, it is estimated that 10 billion plastic bags have been given to shoppers. These will take anything from 100 to 1,000 years to rot. However, it is not as if there is no solution to this. A few years ago, the Irish government introduced a tax on non-recyclable carrier bags and in three months reduced their use by 90%. When he was a minister, Michael Meacher attempted to introduce a similar arrangement in Britain. The plastics industry protested, of course. However, they need not have bothered; the idea was killed before it could draw breath, leaving supermarkets free to give away plastic bags.

   What is clearly necessary right now is some sort of combined initiative, both individual and collective, before it is too late. The alternative is to continue sliding downhill until we have a

country that looks like a vast municipal rubbish tip. We may well be at the tipping point. Yet we know that people respond to their environment. If things around them are clean and tidy, people behave cleanly and tidily. If they are surrounded by dirt, they behave dirtily. Now, much of Britain looks pretty dirty. What will it look like in five years?

 

76. The writer says that it is a good time to see Britain before the trees have leaves because_______.

    A. Britain looks perfect.                                 B. you can see Britain at its dirtiest.

C. you can see how dirty Britain is now.      D. the grass has thickened on the roadside.

77 . According to the writer, the major problem is that __________.

A. rubbish can not be cleared up                        B. rubbish lasts longer than it used to

C. our society is increasingly mobile                  D. people in Britain are dirty

78. What can be learned about Michael Meacher?

A. He followed the Irish example with a tax on plastic bags.

B. He failed in his attempt to introduce a tax on plastic bags.

C. His attempt to follow the Irish example with a tax on plastic bags was welcomed.

D. He had problems with the plastics industry who weren’t bothered about the tax.

79. What does the writer state in the last paragraph?

A. It’s too late for people to take immediate action.

B. There is more than one solution to the problem.

C. Britain will become an extremely dirty country in five years.

D. People tend to behave according to what they see around them.

Ghostwriters are widely used by celebrities or public figures who wish to publish their autobiographies (自传). The degree of involvement of the ghostwriter in nonfiction writing projects ranges from minor to significant. Various sources explain the role of the ghostwriter and how competent (能胜任的) writers can get this kind of work. In some cases, a ghostwriter may be called in just to clean up, edit, and polish a rough draft of an autobiography or a “how-to” book. In other cases, the ghostwriter will write an entire book or article based on information, stories, notes, and an outline, interviews with the celebrity or public figure. The credited authors also indicate to the ghostwriter what type of style, tone, or “voice” they want in the book.

Celebrity books are usually ghostwritten in the first person (I did this and that) or the third person (David Pardon asked the group to recommend someone etc.).

In some cases, such as with some “how-to” books, diet guides, or cookbooks, a book will be entirely written by a ghostwriter, and the celebrity (e.g., a well-known musician or sports star) will be credited as author. Publishing companies use this method to increase the marketability of a book by associating it with a celebrity or well-known figure. In several countries before elections, candidates employ ghostwriters to produce autobiographies for them so as to gain visibility and exposure. Two of John F. Kennedy’s books were almost entirely ghostwritten. Former President Ronald Reagan also released a ghostwritten autobiography.

A consultant or career-switcher may pay to have a book ghostwritten on a topic in their professional area, to establish or enhance their credibility as an “expert” in their field. For example, a successful salesperson hoping to become an inspiring speaker on selling may pay a ghostwriter to write a book on sales techniques. Often this type of book is published in the vanity press, which means that the author is paying to have the book published. This type of book is typically given away to potential clients (客户) as a promotional tool, rather than being sold in bookstores.

 

72. A ghostwriter does all the following EXCEPT ______ for his client, according to the passage.

A. correct a piece of writing                      B. write a complete book

C. improve a written article                       D. interview a celebrity

73. By using “this method” (paragraph 3), the writer means ______.

A. celebrities may help to increase sales

B. celebrities may shift into ghostwriters

C. authors may sometimes become celebrities

D. celebrities may pay publishers for promotion

74. It is implied in the passage that ______.

A. vanity presses are illegal

B. ghostwriters work behind the scene

C. books by ghostwriters don’t sell

D. celebrities can’t do without ghostwriters

75. Which of the following is NOT mentioned about ghostwriters?

A. People who employ them.                    B. Responsibilities they take on.

C. Challenges their work involves.             D. Reasons why they ghostwrite.

Winter is a great time to experiment with new sports. The key is to find one that matches your interests and natural abilities. If you like to walk, keep walking ― on snowshoes. If you want to try an endurance sport, go for cross-country skiing. Besides, snowboarding is just great fun.

Not satisfied with these? Try downhill skiing, then. Downhill skiing is not as hard as it used to be ― shorter, lightweight, curved skis make any beginner feel like an Olympic winner. These newer skis ― along with another type of equipment called skiboards, which are even shorter than skis ― help you control your speed and body movements.

Consider testing the latest high-tech skis or snowboardsCheck with your local sports shops or the rental places at the ski mountains about sample programs.

You could also try sledding. Use a wood-framed sled with steel runners or a plastic sled to head down a snowy hill. If you prefer ice to snow, think hockey or figure skating.

Runners can also train during the winter in spite of wet or slippery roads. One of the easiest sports around, snowshoeing can be excellent cold-weather cross-training for runners and cyclists ― or anyone wanting to take a wintry walk in the woods. Snowshoes are smaller, lighter, and better than ever. If you want to try them out, you may be able to rent a pair for a day at many of the larger outdoor or sporting goods stores.

Whatever sport you choose, don’t rely on a friend for instruction. You wouldn’t let an inexperienced doctor perform a brain operation on you, but why let one teach you to ski or skate? That’s what instructors are for ― to help newcomers start out right. Instructors can give you advice about equipment, techniques, safety, and dealing with injuries if they do happen to you.

Above all, if you want to progress, invest your time in learning the basic skills thoroughly. Everything else you do as a skier, boarder, or skater will be built on these first skills.

 

72.     How many different types of sports are mentioned in the first two paragraphs?

A. Six.                   B. Five.                     C. Four.                     D. Three.

73.     What can we learn from the passage?

A. Runners and cyclists cannot train because of the wet or slippery roads in winter.

B. Downhill skiing used to be more difficult to learn because of the old-fashioned skis.

C. People can rent snowshoes for a day at their local sports shops or the rental places.

D. In general, first skills are more important in skiing than in snowboarding or skating.

74.     What does the sentence “You wouldn’t let an inexperienced doctor perform a brain operation on you, but why let one teach you to ski or skate?” imply?

A. Don’t let an inexperienced doctor perform an operation on you when injured.

B. You may have a brain operation if you ski or skate with a newcomer.

C. Instructors can give better advice on skiing and skating than your friends do.

D. It’s dangerous to have an inexpert person teach you to ski or skate.

75.     Who are the most likely readers of the passage?

A. High school students.                     B. Physical educators.

C. Winter sports lovers.                     D. Professional athletes.

For most of us, the purpose of the holidays is to bring peace, love, and goodwill towards all. Yet, for many, the holiday season often means stress, fatigue, pressure, disappointment and loneliness.

These feelings, often known as the “holiday blues”, may be even more prevalent, due to the emotional turmoil (波折) of the past few months, not to mention the unsteady economy. Experts say even the more ritual tasks of shopping, decorating, late-night parties, cooking, planning and family reunions can be holiday stressors. In addition, the psychological phenomenon known as seasonal affective disorder, or SAD, may bring a specific type of depression related to winter’s shorter days and longer nights.

“Certainly just because it’s the holidays doesn’t mean people are going to be happy,” says Dr. Doug Jacobs of Harvard University. “And this will be a particularly hard holiday for some who are dealing with a lost job, debt, or even a lost loved one.”

And with family reunions becoming less frequent events over the years, there is now the added pressure of getting just one chance to get it all right. “Families are much more different now. The disappointment and sense of alienation that often results from family gatherings, is actually a realization that the fantasy is not met.” says John Stutesman, a clinical psychologist at Northwestern Memorial Hospital in Chicago.

Still, say experts, the blues should be addressed. The most essential step, says Stutesman, is for the individual to acknowledge their feelings and the reason for their withdrawal. “Denial will only compound the stress they’re feeling.” Stutesman recommends people do things that are normally comforting in order to get a handle on the holiday stress. “If they’re feeling a little blue, they should try to do things personally satisfying for them. Maybe this is exercise, cooking, reading a book, or massage.” Stutesman also advises that sometimes “avoidance is actually not such a bad idea.” In some situations, fulfilling social obligations may be self-destructive when the best thing may be to just stay home. The healthy choice has to do with taking care of oneself.”

 

76. What is the “holiday blues”?

A. The feeling of disappointment and sense of alienation in family reunions.

B. Feelings such as stress, fatigue, disappointment and alienation in holiday.

C. Feelings such as peace, love, and goodwill in holiday.

D. The psychological phenomenon known as seasonal affective disorder.

A. Emotional turmoil of the past few months.

B. Summer’s longer days and shorter nights.

C. Unsteady financial condition.

D. Ritual tasks of daily life.

78. Who are more likely to feel blue in holiday according to the passage?

A. Those who are fond of family reunions.

B. Those who are dissatisfied with their relatives.

C. Those who feel frustrated in their work.

D. Those who feel hard to take care of themselves.

79. If you are feeling blue, what can you do to relieve the stress according to the passage?

A. Deny that you are in low spirits.

B. Acknowledge the feeling and let it be.

C. Stay at home and do nothing.

D. Do exercise, cooking, reading or massage.

A.      Profits enlarging

B.      Technology developing

C.      Education investing

D.     Benefits transferring

E.      Dominance disappearing

F.      A nation rising

The following is an imaginary diary entry written by US president. This diary is part of Global Trends 2025, which was written by the US National Intelligence Council

80          

The US lead in highly skilled labor will likely narrow. China will begin to harvest more shares in investments in human capital, including education, nutrition and healthcare. India faces a challenge because top-flight educational institutions tend to satisfy a relatively advantaged few

81          

The US will remain the single most important actor in 2025, but it will be less dominant. It will preserve its considerable military advantages, but its scientific and technological advances will slow. US policy is likely to be strongly determined by the developments in a number of key states, particularly China and Russia

82          

Global wealth and economic power will shift from West to East. Brazil, Russia, India and China (BRIC) are picked as countries which could benefit. Rising oil and commodity prices will create large profits for the Gulf states and Russia. A shift in manufacturing and some service industries to Asia will enrich China and India

83          

China is ready to have more impact on the world over the next two decades than any other country. If current trends persist, by 2025 China will have the world’s second largest economy, and its military will play an important role

84          

The transition from old fuels to new will be slow, as will the development of new technologies that present feasible alternatives to fossil fuels or help eliminate food and water problems. All current technologies are inadequate, and new ones will probably not be commercially possible by 2025
