单选题Even as Americans have been gaining weight, they have cut their average fat intake from 36 to 34 percent of their total diets in the past 15 years. And indeed, cutting fat to control or lose weight makes sense. Fat has nine calories per gram. Protein and carbohydrates have just four. Moreover, the body uses fewer calories to metabolize fat than it does to metabolize other foods. Compared with protein and carbohydrates—which break down into amino acids and simple sugars, respectively, and can be used to strengthen and energize the body—dietary fat is more easily converted to body fat. Therefore, it"s more likely to stay on buttocks, thighs and bellies. But cutting fat from your diet doesn"t necessarily mean your body won"t store fat. For example, between nonfat and regular cookies, there"s trivial difference in calories because manufacturers make up for the loss of fat by adding sugar. Low-fat crackers, soups and dressings can also be just as high in calories as richer versions. No matter where the calories come from, overeating will still cause weight gain. The calories from fat just do it a little quicker. A Wisconsin computer programmer who decided with a diet coach to eat only 40 grams of fat a day learned the lesson firsthand. He wasn"t losing weight. Then he showed his food diary to his coach and revealed he"d been eating half a pound of jelly beans a day. "They don"t have any fat," he explains. But they had enough sugar to keep him from shedding an ounce. Nonfat foods become add-on foods. When we add them to our diet, we actually increase the number of calories we eat per day and gain weight. That was borne out in a Pennsylvania State University study. For breakfast, Prof. Barbara Rolls gave two groups of women yogurt that contained exactly the same amount of calories. One group"s yogurt label said "high fat"—the other, "low fat." The "low fat" yogurt group ate significantly more calories later in the day than the other group. "People think they"ve saved fat and can indulge themselves later in the day with no adverse consequences," says Richard Mattes, a nutrition researcher at Purdue University. "But when they do that, they don"t compensate very precisely, and they often end up overdoing it."

单选题4 Mr. Abu, the laboratory attendant, came in from the adjoining store and briskly cleaned the blackboard. He was a retired African sergeant from the Army Medical Corps and was feared by the boys. If he caught any of them in any petty thieving, he offered them the choice of a hard smack on the bottom or of being reported to the science master. Most boys chose the former as they knew the matter would end there with no long interviews, moral arguments and an entry in the conduct book. The science master, a man called Vernier, stepped in and stood on his small plat- form. Vernier set the experiments for the day and demonstrated them, then retired behind the "Church Times" which he read seriously in between walking quickly along the rows of laboratory benches, advising boys. It was a simple heat experiment to show that a dark surface gave out more heat by radiation than a bright surface. During the class, Vernier was called away to the telephone and Abu as not about, having retired to the lavatory for a smoke. As soon as a posted guard announced that he was out of sight, minor pandemonium (混乱) broke out. Some of the boys raided the store. The wealthier ones took rubber tubing to make catapults and to repair bicycles, and helped themselves to chemicals for developing photographic films. The poorer boys, with a more determined aim, took only things of strict commercial interest which could be sold easily in the market. They emptied stuff into bottles in their pockets. Soda for making soap, magnesium sulphate for opening medicine, salt for cooking, liquid paraffin for women's hairdressing, and fine yellow iodoform powder much in demand for sprinkling on sores. Kojo objected mildly to all this. "Oh, shut up!" a few boys said. Sorie, a huge boy who always wore a fez indoors, commanded respect and some leadership in the class. He was gently drinking his favorite mixture of diluted alcohol and bicarbonate—which he called "gin and fizz"--from a beaker. "Look here, Kojo, you are getting out of hand. What do you think our parents pay taxes and school fees for? For us to enjoy—or to buy a new car every year for Simpson?" The other boys laughed. Simpson was the Europe an headmaster, feared by the small boys, adored by the boys in the middle school, and liked, in a critical fashion, with reservations, by some of the senior boys and African masters. He had a passion for new motor-cars, buying one yearly. "Come to think of it," Sorie continued to Kojo, "you must take something yourself, then we'll know we are safe. " "Yes, you must," the other boys insisted. Kojo gave in and, unwillingly, took a little nitrate for some gunpowder experiments which he was car rying out at home. "Someone!" the look-out called. The boys ran back to their seats in a moment. Sorie washed out his mouth, at the sink with some water. Mr. Abu, the laboratory attendant, entered and observed the innocent expression on the faces of the whole class. He looked round fiercely and suspiciously, and then sniffed the air. It was a physics experiment, but the place smelled chemical. However, Vernier came in then. After asking if anyone was in difficulties, and finding that no one could in a moment think up anything, he retired to his chair and settled down to an article on Christian reunion.
