[单项选择] Biotechnology
Biotechnology in one form or another has flourished since prehistoric times. When the first human beings realized that they could plant their own crops and breed their own animals, they learned to use biotechnology. The discovery that fruit juices fermented(发酵) in wine, or that milk could be converted into cheese or yogurt(酸乳酶) or that beer could be made by fermenting solutions of malt(麦芽) and hops(啤酒花) began the study of biotechnology.

[单项选择] Bathing In the Sea
Bathing in the sea in England a hundred years ago was not quite the light-hearted amusement that it is today. There are no running down from the hotel to the beach in a bath robe(长袍) , no sunbathing, or lying about on the sands in bathing-dresses after the dip. Everything had to be done in an orderly and extremely polite manner. Mixed bathing was not allowed anywhere. Men and women each had their separate part of the beach, and they were not supposed to meet in the water.
Bathing clothes were also closely controlled. Men usually wore simple bathing drawers and no more, but women were obliged to wear thick, cumbersome woolen garments that covered them completely from head to foot. These satisfied the demands of modesty, but they must have been extremely uncomfortable for swimming.

[单项选择] Adaptation of Living Things
Certain animals and plants develop characteristics that help them cope with their environment better than others of their kind. This natural biological process is called adaptation. Among the superior characteristics developed through adaptation are those that may help in getting food or shelter, in providing protection, and in producing and protecting the young. That results in the evolution of more and more organisms that are better fitted to their environments.
Each living thing is adapted to its way of life in a general way, but each is adapted especially to its own distinct class. A plant, for example, depends upon its roots to fix itself firmly and to absorb water and inorganic chemicals. It depends upon its green leaves for using the sun’’s energy to make food from inorganic chemicals. These are general adaptations, common to most plants. In addition, there are special adaptations that only certain kinds of plant
A. help others of their kind get food, shelter and other things needed.
B. survive even in extremely severe conditions
C. become better adapted to the environments than others of their kind.
D. result in the evolution and production of more intelligent organisms.

[单项选择]Food And Cancer
Medical experts have suspected for many years that there is a strong link between what a person eats and cancer._________(46). A team of Chinese and American scientists did the study. They are from American National Cancer Institute and the Cancer Institute of the Chinese Academy of Medical Sciences in Beijing. The Journal of the National Cancer Institute published the results of the study. About thirty thousand people between the ages of 40 to 69 took part in the study. They were from the northern central Chinese area of Linxian. Most of them took vitamins and minerals every day for five years.
_________(47). Researchers believe that fungus and molds in local foods may be partly responsible for the high cancer rate. Researchers divided those into eight groups. Seven of the groups received different mixtures of vitamins and minerals daily. The amounts of the vitamins and minerals were 1 to 2 times greater than what American health officials say is needed._____

[单项选择] One Good Reason to Let Smallpox Live
It’’s now a fair bet that we will never see the total extinction of the smallpox virus. The idea was to cap the glorious achievement of 1980, when smallpox was eradicated in the wild, by destroying the killer virus in the last two labs that are supposed to have it—one in the US and one in Russia.
