问题 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.
选项
答案
解析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。
