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. 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.

Passage One
A few minutes ago, walking back from lunch, I started to cross the street when I heard the sound of a coin dropping. It wasn’t much hut, as I turned, my eyes caught the heads of several other people turning too. A woman had dropped what appeared to be a dime.
The tinkling sound of a coin dropping on pavement is an attention-getter. It can be nothing more than a penny. Whatever the coin is, no one ignores the sound of it. It got me thinking about sounds again.
We are besieged by so many sounds that attract the most attention. People in New York City seldom turn to look when a fire engine, a police car or an ambulance comes screaming along the street.
When I’m in New York, I’m a New Yorker. I don’t turn either. Like the natives. I hardly hear a siren there.
At home in my little town in Connecticut, it’s different. The distant wail of a police car, an emergency vehicle or a fire siren brings me
A. They make him feel at home.
B. He thinks they should be ignored.
C. He believes they are part of our lives.
D. He prefers silence to loud noises.
Passage Five Few Americans remain in one position or one place for a lifetime. We move from town to city to suburb, from high school to college in a different state, from a job in one region to a better job else where, from the home where we raise our children to the home where we plan to live in retirement. With each move we are forever making new friends, who become part of our new life at that time. For many of us summer is a special time for forming new friendships. Today millions of Americans vacation abroad, and they go not only to see new sights but also with the hope of meeting new people. No one really expects a vacation trip to produce a close friend, but the beginning of a friend ship is possible. The word "friend" can be applied to a wide range of relationships--to someone one has known for a few weeks in a new place, to a fellow worker, to a childhood playmate, to a man or woman, to a trusted confidant(知己).
