21、Read the following four texts. Answer the questions below each text by choosing A, B, C or D . Mark your answers on ANSWER SHEET 1. 40 A study by scientists in Finland has found that mobile phone radiation can cause changes in human cells that might affect the brain, the leader of the research team

22、said. But Darius Leszczynski, who headed the 2-year study and will present findings next week at a conference in Quebec (魁北克 ), said more research was needed to determine the seriousness of the changes and their impact on the brain or the body. The study at Finlands Radiation and Nuclear Safety Auth

23、ority found that exposure to radiation from mobile phones can cause increased activity in hundreds of proteins in human cells grown in a laboratory, he said. “We know that there is some biological response. We can detect it with our very sensitive approaches, but we do not know whether it can have a

24、ny physiological effects on the human brain or human body,“ Leszczynski said. Nonetheless the study, the initial findings of which were published last month in the scientific journal Differentiation, raises new questions about whether mobile phone radiation can weaken the brains protective shield ag

25、ainst harmful substances. The study focused on changes in cells that line blood vessels and on whether such changes could weaken the functioning of the blood-brain barrier, which prevents potentially harmful substances from entering the brain from the bloodstream, Leszczynski said. The study found t

26、hat a protein called hsp27 linked to the functioning of the blood-brain barrier showed increased activity due to irradiation and pointed to a possibility that such activity could make the shield more permeable(能透过的 ), he said. “Increased protein activity might cause cells to shrink not the blood ves

27、sels but the cells themselves and then tiny gaps could appear between those cells through which some molecules could pass. “ he said. Leszczynski declined to speculate on what kind of health risks that could pose, but said a French study indicated that headache, fatigue and sleep disorders could res

28、ult. “These are not life-threatening problems but can cause a lot of discomfort,“ he said, adding that a Swedish group had also suggested a possible link with Alzheimers disease. “Where the truth is I do not know,“ he said. Leszczynski said that he, his wife and children use mobile phones, and he sa

29、id that he did not think his study suggested any need for new restrictions on mobile phone use. 41 According to Leszczynski, how does mobile phone affect ones health? （ A） Mobile phone radiation can increase protein activities and such activities can make the protective shield more permeable. （ B） M

30、obile phone radiation can shrink the blood vessels and prevent blood from flowing smoothly. （ C） Mobile phone radiation will bring stress to people exposed to it. （ D） Mobile phone radiation kills blood cells at a rapid speed. 42 Whats the result of the French study? （ A） The harm of mobile phone ra

31、diation is life-threatening. （ B） Mobile phone may affect ones normal way of thinking. （ C） Sleep disorders could result from mobile phone radiation. （ D） A protein called hsp27 is killed by mobile phone radiation. 43 What kind of disease is not caused by the use of mobile phone? （ A） Fatigue. （ B）

32、Headache. （ C） Alzheimers disease. （ D） Tuberculosis. 44 According to the passage, what would be the future of the use of mobile phone? （ A） People will be forbidden to use mobile phone. （ B） People dare not use mobile phone because of its radiation. （ C） People will continue to use mobile phone. （

33、D） There will be new restrictions on the use of mobile phone. 45 Which of the following is NOT true according to the passage? （ A） The research in Finland found that mobile phone radiation will affect ones brain. （ B） Mobile phone radiation can cause increased activity in hundreds of protein in huma

34、n cells. （ C） Increased protein activity might cause cells to shrink. （ D） Lszczynski forbade his wife and children to use mobile phone after his research. 45 Every second in the United States alone, more than 250 animals are slaughtered for food, adding up to more than 8 billion animals each year.

35、Reducing the amount of meat in ones diet is nutritionally, environmentally, and ethically beneficial. People who eat meat usually have weaker immune systems compared to those of vegetarians. Meat has been directly linked to diabetes, obesity, arthritis, and many other illnesses. Furthermore, meat-ea

36、ters are at a higher risk for diseases, including cancer, and they are more likely to die from these diseases. Critics say that a meatless diet does not provide e-nough nutrients, especially protein and iron. Actually, according to “A Teens Guide to Going Vegetarian“, by Judy Krizmanic, protein is f

37、ound in almost every food, and iron appears in many vegetables. Getting enough nutrients in a meat-reduced diet should not be difficult. A 1988 study found that some of the highest pesticide residues appear in meat and eggs. Diets including more fruits and vegetables will only make people healthier.

38、 Some skeptics believe that there will be a shortage of food if animals are not eaten. In fact, the opposite is true. More than 80% of the corn and 95% of the oats grown in the U. S. are fed to livestock. The worlds cattle alone consume enough food to equal the caloric needs of 8. 7 billion people,

39、more than the entire human population. One half of the water used in the Unites States also goes to livestock; 250 gallons of water produces only 1 lb. of beef. If people eat less meat and more plants, the amount of available food will increase. Many people become vegetarians because they feel that

40、eating animals is unethical. 90% of these animals are raised in confinement. Chickens and other birds have only about half a square foot of space each, and since they are raised so close together, a lot blade is used to cut off their beaks to prevent them from pecking each other to death. Likewise,

41、pigs that are repressed will bite each others tails, so both their teeth and tails are removed as soon as they are born. Eating animals is hazardous in numerous ways. Even a slight reduction in meat intake is better than nothing at all. Consuming less meat is beneficial to the health of animals, the

42、 health of people, and the health of the world. 46 Why do some people become vegetarians? （ A） They feel that eating animals is unethical. （ B） There are fewer livestock available due to the environmental pollution. （ C） The consumption of meat will lead to financial problem. （ D） Being a vegetarian

43、 is beneficial to the protection of water. 47 Which of the following statements is true according to the book “A Teens Guide to Going Vegetarian“? （ A） Some of the highest pesticide residues appear in meat and eggs. （ B） A meatless diet does not provide enough nutrients. （ C） Protein can be found in

44、 almost every food. （ D） More than 80% of the corn in the U. S. are fed to livestock. 48 Why does the author say reducing the amount of meat in ones diet is environmentally beneficial? （ A） People who eat meat usually have weaker immune systems compared to those of vegetarians. （ B） A lot of food an

45、d water are consumed in order to raise livestock. （ C） 90% of animals are raised in confinement. （ D） Raising Animals causes most of the destruction of the nature. 49 What is the attitude the author has toward eating meat? （ A） Positive. （ B） Negative. （ C） Indifferent. （ D） None of the above. 50 Wh

46、ich of the following can be the best title of the passage? （ A） The Advantage of Eating Less Meat. （ B） Why People Become Vegetarian? （ C） Environmental Protection and Meatless Diet. （ D） Save Chickens, Save Birds. 50 Opinion polls are now beginning to show an unwilling general agreement that, whoev

47、er is to blame and whatever happens from now on, high unemployment is probably here to stay. This means we shall have to find ways of sharing the available employment more widely. But we need to go further. We must ask some fundamental questions about the future of work. Should we continue to treat

48、employment as the norm? Should we not create conditions in which many of us can work for ourselves, rather than for an employer? Should we not aim to revive the household and the neighbourhood, as well as the factory and the office, as centres of production and work? The industrial age has been the

49、only period of human history in which most peoples work has taken the form of jobs. The industrial age may now be coming to an end, and some of the changes in work patterns which it brought about may have to be reversed. This seems a discouraging thought. But, in fact, it could offer the prospect of a better future for work. Universal employment, as its history shows, has not meant economic freedom. Employment became widespread when the enclosures o
