18、there are 4 choices marked A, B, C, and D. You should make the correct choice. 36 It is clear that some people who participate in exercise training will develop injuries to their bones, muscles, and joints(关节 ). Despite unfounded reports in the mass media of extremely high injury rates among adult e

19、xercisers, there have been few good studies of exercise injuries in populations. One of the difficulties in performing such studies has been the need to identify both the number of cases and the number of people at risk for injury. In other words, it is difficult to know the number of individuals in

20、jured and the total number of individuals exercising in the population. But these two figures are necessary in order to calculate(统计 ) true injury rates. Normally, injury is defined as an accident that causes a person to stop exercising for at least one week. The best available studies on injury rat

21、es show that about 25 to 30 percent of adult runners become “injured“ (based on the above definition) over the course of a year. More serious injuries include those for which the injured person seeks medical care. If only they are considered, injury rates are much lower, perhaps in the range of 1 pe

22、rcent per year. Little is known about the causes of exercise injuries. One factor that has been linked to injury is the amount of exercise; for example, individuals who run more miles are likelier to be injured than those who run fewer miles. Factors such as age, sex, body type, and experience have

23、not been shown to be associated with risk of injury. It seems logical that structural abnormalities, sudden increases in training intensity, and types of equipment used are likely to be related to injury risk. However, data to support these opinions are not available. 36 What is the writers attitude

24、 towards high injury rates among adult exercisers reported by the mass media? （ A） Positive. （ B） Indifferent. （ C） Negative. （ D） Reserved. 37 The true injury rates are obtained from （ A） the average number of injuries for each individual （ B） the amount of exercises for each individual （ C） the nu

25、mbers of the injured and all individuals in training （ D） the numbers of people doing exercises and those stopped exercises for one week 38 Which of the following is NOT shown as the factor for causing exercise injuries? （ A） The amount of exercise. （ B） The age, sex and body type. （ C） Structural a

26、bnormalities. （ D） The sudden increases in training intensity. 39 The factors that are in relation to exercises injuries （ A） have been obtained from many good studies （ B） have been confirmed by many data （ C） cannot confirm the risk of equipment types （ D） can be proved easily by the data through

27、calculation 40 The passage is mainly about _. （ A） the high injury rates for those doing exercises （ B） the ways to avoid exercise injuries （ C） the evidences for the seriousness of exercise injuries （ D） the studies about injury rates and causes for injuries Task 2 Directions: This task is the same

28、 as Task 1. The 5 questions or unfinished statements are numbered 41 through 45. 41 Too much metal in the soil is considered pollution. Yet too little metal in a persons diet can cause health problems. An American scientist says the answer to both problems may be plants that take up large amounts of

29、 metal in their tissues. David Salt is an expert on plants at Purdue University in West Lafayette, Indiana. He is working with plants that store large amounts of metals. In recent years, scientists have shown interest in using such plants to clean up harmful waste materials, Professor Salt says such

30、 plants also could be used to improve peoples diets or even to create foods that fight cancer. Humans need a number of metals in their diets, including iron and zinc. These metals are needed in very small amounts, however. That is why they are called micronutrients. The lack of micronutrients is bla

31、med for health problems in many developing countries. Children and pregnant women are mostly affected. Recently, Mr. Salt announced that he has identified and copied the genes from a kind of plant that stores metals in its tissues. He says his study suggests it may be possible to develop plants that

32、 contain minerals needed for good health. For example, the metal selenium is a strong anti-cancer agent. Some wild plants store selenium naturally. Mr. Salt says foods to fight cancer might be created if genes from these plants could be moved into crop plants. Locoweed, which is a common plant in th

33、e western U. S., stores selenium. Professor Salt says it may be possible to create cancer-fighting foods from it. He and scientists from a company called Unicycle Therapies have copied the gene that causes locoweed to take up selenium from the soil. Many people take pills to add important minerals o

34、r vitamins to their diet. However, Mister Salt notes that most selenium products sold in health food stores are of little use. That is because the human body can only take in and use selenium if it is in the right chemical form. The scientist says his team would like to develop a vegetable crop high

35、 in selenium. He wants to create an anti-cancer product in the foods we already eat. 41 According to Pro. Salt, plants that take up large amounts of metal in their tissues can be used to _. （ A） clean polluted soil and cure disease like cancer （ B） clean up harmful waste materials in soil and improv

36、e peoples diet （ C） produce large number of micronutrients such as iron and zinc （ D） create food with important minerals or vitamins 42 In many developing countries, people fall sick because _. （ A） they dont absorb enough micronutrients from their diet （ B） they dont have plants that take up metal

37、 in their tissues （ C） there is no locoweed in their countries （ D） there is no iron and zinc containing in their food 43 Mr. Salt wants to create anti-cancer foods by _. （ A） copying tissues from wild plants that take up selenium naturally into crop plants （ B） copying genes that causes the plants

38、to take up selenium from the soil （ C） moving selenium from the tissues of wild plants into crop plants （ D） moving genes from wild plants that take up selenium naturally into crop plants 44 To add selenium by taking pills are probably not effective because _. （ A） the human body is not in the right

39、 chemical form （ B） the human body does not accept it （ C） the selenium is, not in the right chemical form to be absorbed （ D） the selenium is difficult to absorb 45 What is the main idea of the article? （ A） Plants that absorb metals are being studied by scientists. （ B） Scientists are trying to cr

40、eate cancer-fighting crops. （ C） Some wild plants can store micronutrients naturally. （ D） Anti-cancer products in the foods are good to peoples diet.
