5、       Exercise is one of the few factors with a positive role in long term maintenance of body weight. Unfortunately, that message has not gotten through to the average American, who would rather try switching to “l(fā)ight” beer and low - calorie bread than increase physical exertion. The Centers for Disease Control, for example, found that fewer than one - fourth of overweight adults who were trying to shed pounds said they were combining exercise with their diet.

　　In rejecting exercise, some people may be discouraged too much by caloric - expenditure charts; for example, one would have to briskly(興致勃勃地) walk three miles just to work off the 275 calories in one delicious Danish pastry (小甜餅). Even exercise professionals concede（承認） half a point here. “Exercise by itself is a very tough way to lose weight,” says York Onnen, program director of the President’s Council on Physical Fitness and Sports.

　　Still, exercise’s supporting role in weight reduction is vital. A study at the Boston University Medical Center of overweight police officers and other public employees confirmed that those who dieted without exercise regained almost all their old weight, while those who worked exercise into their daily routine maintained their new weight.

　　If you have been sedentary (極少活動的) and decide to start walking one mile a day, the added exercise could burn an extra 100 calories daily. In a year’s time, assuming no increase in food intake, you could lose ten pounds. By increasing the distance of your walks gradually and making other dietary adjustments, you may lose even more weight.

71．What is said about the average American in the passage?

       A．They tend to exaggerate（夸張）the healthful effect of “l(fā)ight” beer.

       B．They usually ignore the effect of exercise on losing weight.

       C．They prefer “l(fā)ight” beer and low-calorie bread to other drinks and food.

       D．They know the factors that play a positive role in keeping down body weight.

72．Some people dislike exercise because ________.

       A．they think it is physically exhausting

       B．they find it hard to exercise while on a diet

       C．they don’t think it possible to walk 3 miles every day

       D．they find consulting caloric-expenditure charts troublesome

73．“Even exercise professionals concede half a point here” (Line 3, Para. 2) means “They ________”.

       A．a(chǎn)gree that the calories in a small piece of pastry can be difficult to work off by exercise

       B．partially believe diet plays a supporting role in weight reduction

       C．a(chǎn)re not fully convinced that dieting can help maintain one’s new weight

       D．a(chǎn)re not adequately informed of the positive role of exercise in losing weight

74．What was confirmed by the Boston University Medical Center’s study?

       A．Controlling one’s calorie intake is more important than doing exercise.

       B．Even occasional exercise can help reduce weight.

       C．Weight reduction is impossible without exercise.

       D．One could lose ten pounds in a year’s time if there’s no increase in food intake.

75．What is the author’s purpose in writing this article?

       A．To justify the study of the Boston University Medical Center.

       B．To stress the importance of maintaining proper weight.

       C．To support the statement made by York Onnen.

       D．To show the most effective way to lose weight.

4、       Some scientists have suggested that it might in some cases be ethically(倫理的) acceptable to clone existing people. One possibility is generating replacement for a dying relative. All such possibilities, however, raise the concern that the clone would be treated as less than a complete individual, because he or she would likely suffer from limitations and expectations based on the family’s knowledge of the genetic “twin.” Those expectations might be false, because human personality is only partly determined by genes. The clone of an extrovert(性格外向的人) could have a quite different way of behavior. Clones of athletes, movie stars, or scientists might well choose different careers because of chance events in early life.

       Some people have also put forward the belief that couples in which one member is infertile (不生育)might choose to make a copy of one or the other partner. But society ought to be concerned that a couple might not treat naturally a child who is a copy of just one of them. Because other methods are available for the treatment of all known types of infertility, the traditional choice seems more appropriate. None of the suggested uses of cloning for making copies of existing people is ethically acceptable to my way of thinking, because they are not in the interests of the resulting child. It should go without saying that I am strongly opposed to allowing cloned human embryos(胚胎) to develop so that they can be tissue donors.

       In spite of this, it seems clear that cloning from cultured(人工培育的) cells will offer important medical opportunities. Predictions about new technologies are often wrong: societal attitudes change; unexpected developments occur. Time will tell. But biomedical researchers looking into the potential of cloning now have plenty to do.

66．What is the author’s concern about cloning an existing person?

       A．The clone created will have one defect（缺陷）or another.

       B．The clone created will be mistreated.

       C．The clone created is unlikely to fulfill your expectations.

       D．The clone created is ethically unacceptable.

67．It can be inferred from the text that a clone will _________.

       A．choose the same career as the person it is created from

       B．behave in the same way as the person it is created from

       C．share the same characteristics with the person it is created from

       D．be partly similar in personality to the person it is created from

68．According to the passage, one’s personality is determined by ___________.

       A．their genes

       B．the environment they live in

       C．both their genes and the environment they live in

       D．neither their genes nor the environment they live in

69．In the author’s view, which of the following uses of cloning is reasonable?

       A．To replace a lost relative.

       B．To help childless couples to have a baby.

       C．To develop tissue donors.

       D．To culture cells for medical purpose.

70．What is the author’s attitude towards cloning technology?

       A．It should be condemned.

       B．It has medical potential for scientists to explore.

       C．It should wait till people’s views change.

       D．It was unethical from the very beginning.
