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In the US, people prefer waiting for a table to sitting with people they don't know. This means a hostess may not seat a small group until a small table is available, even if a large one is. If you are sitting at a table with people you don't know, it is impolite to light up a cigarette without first asking if it will disturb them. At American restaurants and coffee shops you are usually served tap water before you order. You may find the bread and butter is free, and if you order coffee, you may get a free refill. Most cities and towns have no rules about opening and closing times for stores or restaurants, though they usually do make rules for bars. Especially in large cities, stores may be open 24 hours a day. Servings in restaurants are often large, too large for many people. If you can't finish your meal but would like to enjoy the food later, ask your waitress or waiter for a "doggie bag". It may have a picture of a dog on it, but everybody knows you are taking food for yourself. Supper and dinner are both words for the evening meal. Some people have "Sunday dinner". This is an especially big noon meal. Tips are not usually added to the check. They are not included in the price of the meal, either. A tip of about 15% is expected and you should leave it on the table when you leave. In some restaurants, a check is brought on a plate and you put your money there. Then the waiter or waitress brings you your change.
