单选题Joe is an American who has come to Britain _____.A for a few weeksB not long agoC at the same timeD for the first time

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.

单选题Physical exertion on the part of a person who has fallen into cold water would（）.A be the best thing to try if there was no rescue in sightB increase survival time in the waterC increase the rate of heat loss from the bodyD not affect the heat loss from the body

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 said about the average American in the passage? （）A、They tend to exaggerate the healthful effect of “light” beer.B、They usually ignore the effect of exercise on losing weight.C、They prefer “light” 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.
