Questions 26 to 30 are based on the following passage. 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 “light” 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 walk three miles just to work off the 275 calories in one delicious Danish pastry (小甜饼). Even exercise professionals concede 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 (极少活动的) 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. 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.

    Question 51-52refer to the following information.
    The bad news about a slow-but-steady recovery is clear: lingering long-term unemployment, stagnant wages, and a housing recovery that is leaving many middle-income families behind. But one interesting side-effect of the boring recovery is that it puts to rest （for now） the popular fears of an AI/robot revolution taking all of our jobs. In that brave neo-industrial world, one thing you would expect to see is GDP growth rapidly outstripping employment, as robots did a bunch of work while Americans sat around waiting for federal welfare checks. Quite the opposite, in the last few years, GDP-per-worker has all but stopped growing.

    Exercise and Brain

    Just as exercise strengthens the heart and lungs,bones and muscles,it may also power up the brain.A succession of scientific studies of animals implies that physical activity has a positive effect on mental functioning.
    "It's clear that the brain benefits from exercise,"says brain scientist William Greenough of the University of Illinois at Urbana-Champaign.His studies with rats have demonstrated two primary effects of activity:Vigorous physical exercise provides the brain with more fuel,and skill-based ex-ercise increases the formation of connections in the brain, which, according to the proposals of some scientists,may make the brain better able to process information.
    In one experiment,laboratory rats were separated into three groups.One group was exercised by running inside an automatic wheel,a second group improved their skills in a complicated obstacle course,and a third group was inactive.
    "The animals that learned to go through the obstacle course exhibited a greater number of brain connections than the animals in the exercised or inactive groups,"Greenough said."In contrast, the animals that exercised inside the automatic wheel possessed a greater density of blood vessels in the brain than did either of the other two groups of animals."
    Learning a new dance step may boost the brain in the same way that learning a language can, he says.And if the dance is a good physical exercise as well,the benefits multiply.Young brains may be especially able to boost brain power through exercise,suggested another of Greenough's experiments that showed the most significant changes in the brain occurred among rats that had been exercised when very young.And while animals aren't people,he says it is logical to make the inference that an effect found in rats may also apply to humans.
    Human studies have focused primarily on older adults and suggest that regular exercise can improve the speed with which the brain processes information.Measurements made by Arthur Kramer at the University of Illinois demonstrated that inactive adults,aged 63 to 82,could hit buttons faster in response to a tone after they went through a 10-week water exercise course.A corresponding control group that didn't exercise showed no improvement.

    According to the passage what is not the advantage of physical exercises?
    A:do good to our mental health.
    B:strengthen our hearts and lungs.
    C:strengthen our bones and muscles.
    D:help us lose weight.

    答案：D
    解析：
    选项A、B、C中提到的锻炼身体的好处在第一段均提到了，只有D项文中没有提到。因此选择D。
    文章第二段第二句提到：高强度体育运动给大脑提供更多的燃料，而技巧性运动则增强大脑神经的联结。依照某些科学家的见解，这种联结能使大脑更好地处理信息。因此选择A项，而B项和C项是技巧性运动的功能，D项不符合文章意思。
    文章第三段和第四段告诉我们选项A应该是。nning inside an automatic wheels；选项B文中没有提到是inside还是outside；选项C应该是a great number of brain connections；选项D是正确的。
    文章第五段第一句告诉我们“学习一种新的舞蹈和学习一种语言一样，都能促进大脑发展。如果这种舞蹈还是一种良好的体育运动，则益处加倍”，因此A和B项都排除。根据文章第三段和第四段，我们知道只有being inactive inside不能促进大脑发展。
    根据文章我们知道选项A里老鼠的实验结果应当可以应用到对人类的研究，因此是错误的；文章第五段告诉我们选项B的表述是正确的；文章第六段告诉我们“经常锻炼能提高大脑处理信息的速度”，但并没有说该实验结果不能应用于其他年龄段的人，因此是错误的；根据文章第二段我们知道两种锻炼对大脑会产生不同的影响，因此选项D也是错误的。

    问答题
    Tomorrow is Tuesday, I’ll spend five minutes warming up on the Versa-Climber. Then I’ll do 30 minutes on a stair mill. On Wednesday a personal trainer will work me like a farm animal for an hour. Thursday is “body wedge” class, which involves another exercise contraption (device). Friday will bring a 5.5-mile run, the extra half-mile my exhausting compensation of any gastrono mical (the art or science of good eating) indulgences during the week.　　I have exercised like this—obsessively, a bit persistently—for years, but recently I began to wonder: Why am I doing this? Except for a two-year period at the end of an unhappy relationship—a period when I self-medicated with lots of Italian desserts—I have never been overweight. One of the most widely accepted, commonly repeated assumptions in our culture is that if you exercise, you will lose weight. But I exercise all the time, and since I ended that relationship and cut most of those desserts, my weight has returned to the same 163 lb. it has been most of my adult life. I still have gut fat that hangs over my belt when I sit. Why isn’t all the exercise wiping it out?　　(1)________________. Of course, some people join and never go. Still, as one major study— the Minnesota Heart Survey-found, more of us at least say we exercise regularly. The survey ran from 1980, when only 47％of respondents said they engaged in regular exercise, to 2000, when the figure had grown to 57％.　　(2) ________________. Yes, it’s entirely possible that those of us who regularly go to the gym would weigh even more if we exercised less. But like many other people, I get hungry after I exercise, so I often eat more on the days I work out than on the days I don’t. Could exercise actually be keeping me from losing weight?　　(3) ________________. Today doctors encourage even their oldest patients to exercise, which is sound advice for many reasons: People who regularly exercise are at significantly lower risk for all manner of diseases—those of the heart in particular. They less often develop cancer, diabetes and many other ill-nesses. But the past few years of obesity research show that the role of exercise in weight loss has been wildly overstated.　　(4) ________________. Many recent studies have found that exercise isn’t as important in holding people lose weight as you hear so regularly in gym advertisements or on shows like The Biggest Loser—or, for that matter, from magazines like this one.　　(5) ________________. That causes us to eat more, which in turn can cancel out the weight-loss benefits we just accrued. Exercise, in other words, isn’t necessarily helping us lose weight. It may even be making it harder.　　(本文选自Time 2009年刊)　　[A] And yet obesity figures have risen dramatically in the same period: a third of Americans are obese, and another third count as overweight by the Federal Government’s definition.　　[B] The conventional wisdom that exercise is essential for shedding pounds is actually fairly new. As recently as the 1960s, doctors routinely advised against rigorous exercise, particularly for older adults who could injure themselves.　　[C] It’s a question many of us could ask. More than 45 million Americans now belong to a health club, up from 23 million in 1993. We spend some $19 billion a year on gym memberships.　　[D] The findings were surprising. On average, the women in all the groups, even the control group, lost weight, but the women who exercised—sweating it out with a trainer several days a week for six months—did not lose significantly more weight than the control subjects did.　　[E] The basic problem is that while it’s true that exercise burns calories and that you must burn calories to lose weight, exercise has another effect: it can stimulate hunger.　　[F] “In general, for weight loss, exercise is pretty useless,” says Eric Ravussin, chair in diabetes and metabolism (any basic process of organic functioning or operating) at Louisiana State University and a prominent exercise researcher.　　[G] Yes, although the muscle-fat relationship is often misunderstood. According to calculations published in the journalObesity Researchby a Columbia University team in 2001, a pound of muscle bums approximately six calories a day in a resting body, compared with the two calories that a pound of fat burns.

    正确答案：
    1. C 作者在前文介绍了自己坚持锻炼的情况,提到if you exercise, you will lose weight的流行观点,但是作者坚持锻炼几年了still have gut fat,并在段末提出自己的疑问Why isn’t all the exercise wiping it out?。选项C首句It’s a question many of us could ask.正好与上文末尾的问题相呼应,故为正确答案。
    2. A 上文已经提到from 1980to 2000越来越多的人非常有规律地进行锻炼,A首句And yet obesity figures have risen dramatically in the same period,其中in the same period指上文运动人群增多的同时期,肥胖人口也在增多,因此,作者在段尾提出:Could exercise actually be keeping me from losing weight? 上下文逻辑关系清楚,故A为正确答案。
    3. B 上文分析了运动与减肥之间的关系,而空缺处下文Today doctors encourage even their oldest patients to exercise中由语气词even可推知,以前年长的病人不被建议进行强烈的锻炼,选项B首句提出通过运动来减肥的做法是进来才兴起的,在1960s的时候,医生不建议老年人剧烈运动,承上启下,其中As recently as与下文的Today在时间上有了承接,故为正确答案。此处干扰项为D,,讲将女性作为实验对象得出结果,本文中虽提及运动对减肥并无多大益处,但是上下文并未提及D中所说的女性参加的不同小组的对比实验,故排除。
    4. F 由前一段落末尾But the past few years of obesity research show that the role of exercise in weight loss has been wildly overstated.可知,锻炼在减肥过程当中所起的作用被夸大,空缺后文又提到运动在帮助人们减肥方面的效果并非人们所想象的那么好,F中In general, for weight loss, exercise is pretty useless正好与上下文一致,故为正确答案。
    5. E 由本空后文That causes us to eat more可知,,选文应该与代词that指代的含义一致。E中末尾it can stimulate hunger是导致我们吃的更多的原因,与下文形成因果联系,故E为正确答案。此处注意干扰项G,本文作者讨论运动与减肥之间的关系时,虽然涉及热量的消耗,但是并未提及the muscle-fat relationship,更不至于有其关系被误解的状况,所以可排除此项。

In rejecting exercise, some people may be discouraged too much by caloric-expenditure charts: for example, one would have to briskly walk three miles just to work off the 275 calories in one delicious Danish pastry (小甜饼). Even exercise professionals concede 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 (极少活动的) 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. Some people dislike exercise because （）

    Passage2         Questions 6 to 10 are based on the following passage.         Salt is as necessary to life as water. In many areas of Africa people once drank the urine（尿）of animals because they had no other source of salt. Without salt, human beings die.          The human body demands that the amount of salt in the blood always stay the same. When the body does not get enough salt, it protects itself by letting less salt leave the body in. urine and sweat. But it cannot reduce this output to zero. Some salt is always escaping. On a completely saltless diet, like that of some people in Africa, the body steadily loses small amounts of salt through the kidneys（肾） and sweat glands(腺). It then tries to adjust to this loss by speeding up its secretion(分泌) of water. (78) In this way, the body attempts to keep the amount of salt in the blood at the necessary level. The result is a slow drying up of body and, finally, death. The person dies of thirst.      In cases where there is little or no water to drink, the body tries to do the opposite thing.Again, it must keep the salt level in the blood constant. Because it has little water, it attempts to stop water from leaving the body and to increase its secretion of. salt. But, as with the escaping salt, it cannot be completely successful. Some water still leaves and the person eventually dies of thirst. In short, the body's normal needs for salt and for water are both parts of the same important need to keep the salt level in the blood constant.8 Which of the following statements is NOT the result of a lack of salt in the body?
    A

    The body secretes more water.

    B

    The body dries up.

    C

    The person dies of thirst.

    D

    The person gets fatter.
