1、【题目】Scattered through the seas of the world are billions of tons of small plants and animals called plankton. Most of these plants and animals are too small for the human eye to see. They drift about lazily with the currents, providing a basic food for many larger animals. Plankton has been described as the equivalent of the grasses that grow on the dry land continents, and the comparison is an appropriate one. In potential food value however, plankton far outweighs that of the land grasses. One scientist has estimated that while grasses of the world produce about 49 billion tons of valuable carbohydrates each year. The sea’s plankton generates more than twice as much.

Despite its enormous food potential, little effort was made until recently to farm plankton as we farm grasses on land. Now marine scientists have at last begun to study this possibility, especially as the sea’s resources loom even more important as a means of feeding an expanding world population.

No one yet has seriously suggested that “planktonburgers” may soon become popular around the world. As a possible farmed supplementary food source, however, plankton is gaining considerable interest among marine scientists.

One type of plankton that seems to have great harvest possibilities is a tiny shrimplike creature called krill. Growing to two or three inches long, krill provide the major food for the giant blue whale, the largest animal ever to inhabit the Earth. Realizing that this whale may grow 100 feet and weigh 150 tons at maturity, it is not surprising that each one devours more than one ton of krill daily.

Krill swim about just below the surface in huge schools sometimes miles wide, mainly in the cold Antarctic. Because of their pink color, they often appear as a solid reddish mass when viewed from a ship or from the air. Krill are very high in food value. A pound of these crustaceans contains about 460 calories—about the same as shrimp or lobster, to which they are related.

If the krill can feed such huge creatures as whales, many scientists reason, they must certainly be contenders as new food source for humans.

1、【题目】Part V Writing

Directions: For this part, you are allowed 30 minutes to write a composition on the topic: Keeping Fit. You should write at least 100—120 words and you should base your composition on the outline (given in Chinese) below:

Obviously, health is more important than anything else we have in this world. Good health is a necessity for us to enjoy our life and pursue our dreams in the society.

Secondly, exercises may keep us very strong. Although each of us is very busy with our daily work and study, we will never forget to spend some time doing exercises. Thirdly, a balanced diet is a must to keep us healthy. We’d better not have too much fat and sugar, which may cause us to become overweight. Vegetables and fruits provide us various vitamins; therefore, do not hesitate to enjoy these foods.

In conclusion, health is very valuable for each of us. If you could follow the advice we’ve proposed above, you will be sure to keep fit and enjoy your happy life.



1、【题目】In the last 12 years total employment in the United States grew faster than at any time in the peacetime history of any country – from 82 to 110 million between 1973 and 1985 – that is, by a full one third. The entire growth, however, was in manufacturing, and especially in no – blue-collar jobs…

This trend is the same in all developed countries, and is, indeed, even more pronounced in Japan. It is therefore highly probable that in 25 years developed countries such as the United States and Japan will employ no larger a proportion of the labor force I n manufacturing than developed countries now employ in farming – at most, 10 percent. Today the United States employs around 18 million people in blue-collar jobs in manufacturing industries. By 2010, the number is likely to be no more than 12 million. In some major industries the drop will be even sharper. It is quite unrealistic, for instance, to expect that the American automobile industry will employ more than one –third of its present blue-collar force 25 years hence, even though production might be 50 percent higher.

If a company, an industry or a country does not in the next quarter century sharply increase manufacturing production and at the same time sharply reduce the blue-collar work force, it cannot hope to remain competitive – or even to remain “developed.” The attempt to preserve such blue – collar jobs is actually a prescription for unemployment…

This is not a conclusion that American politicians, labor leaders or indeed the general public can easily understand or accept. What confuses the issue even more it that the United States is experiencing several separate and different shifts in the manufacturing economy. One is the acceleration of the substitution of knowledge and capital for manual labor. Where we spoke of mechanization a few decades ago, we now speak of “robotization “ or “automation.” This is actually more a change in terminology than a change in reality. When Henry Ford introduced the assembly line in 1909, he cut the number of man – hours required to produce a motor car by some 80 percent in two or three years –far more than anyone expects to result from even the most complete robotization. But there is no doubt that we are facing a new, sharp acceleration in the replacement of manual workers by machines –that is, by the products of knowledge.

1.According to the author, the shrinkage in the manufacturing labor force demonstrates______.

A.the degree to which a country’s production is robotized

B.a reduction in a country’s manufacturing industries

C.a worsening relationship between labor and management

D.the difference between a developed country and a developing country

2.According to the author, in coming 25years, a developed country or industry, in order t remain competitive, ought to ______.

A.reduce the percentage of the blue-collar work force

B.preserve blue – collar jobs for international competition

C.accelerate motor – can manufacturing in Henry Ford’s style

D.solve the problem of unemployment

3.American politicians and labor leaders tend to dislike_____.

A.confusion in manufacturing economy

B.an increase in blue – collar work force

C.internal competition in manufacturing production

D.a drop in the blue – collar job opportunities

4.The word “prescription” in “a prescription for unemployment” may be the equivalent to ______

A.something recommended as medical treatment

B.a way suggested to overcome some difficulty

C.some measures taken in advance

D.a device to dire

5.This passage may have been excepted from ________

A.a magazine about capital investment

B.an article on automation

C.a motor-car magazine

D.an article on global economy








China has a vast land and a large population. Even though the Chinese language is spoken all over the country, people in different areas speak it in different ways, which are called dialects. Generally called local languages, dialects are branches of the Chinese language in different regions, and are only used in certain areas. Dialects of the Chinese language are very complicated. They differ from each other in three aspects: pronunciation ,vocabulary and grammar. And the difference in pronunciation is the most outstanding. Over2,000 years ago, Chinese people realized that a common language should be used in social activities. Compared with dialects,mandarin can be understood by all people. It is beneficial to information transmission and cultural exchange between ethnic groups and people indifferent places..




Culture shock is caused by the anxiety that results from losing all familiar signs and symbols of social intercourse. (Passage Four)








Nowadays, China is stepping into the aging society. Therefore, the only-child generation is facing enormous pressure both from work and life. The Chinese government has begun to adjust the familyplanning policy and allows some families to have a second child under certain circumstances. However, the survey shows thatsome couples abandon to have a second child due to the increasing financial burden. Thus, in order to solve the aging problem,the basic thing is not relying on the increase of birth rate. The best solution is to establish an effective social security system.
