The problem with such a view is that some people actually attempt to live by it. I myself have fantasies of slipping into narrow designer clothes. Consequently, I have been on a diet for the better--or worse--part of my life. Being rich wouldn't be bad either, but that won't happen unless an unknown relative dies suddenly in some distant land, leaving me millions of dollars.
Where did we go off the track？ When did eating butter become a sin, and a little bit of extra flesh unappealing, if not repellent？ All religions have certain days when people refrain from eating, and excessive eating is one of Christianity's seven deadly sins. However, until quite recently, most people had a problem getting enough to eat. In some religious groups, wealth was a symbol of probable salvation and high morals, and fatness a sign of wealth and well-being.
Today the opposite is true. We have shifted to thinness as our new mark of virtue. The result is that being fat--or even only somewhat overweight--is bad because it implies a lack of moral strength.
Our obsession (迷恋) with thinness is also fueled by health concerns. It is true that in this country we have more overweight people than ever before, and that, in many cases, being overweight correlates with an increased risk of heart and blood vessel disease. These diseases, however, may have as much to do with our way of life and our high-fat diets as with excess weight. And the associated risk of cancer in the digestive system may be more of a dietary problem--too much fat and a lack of fiber--than a weight problem.
The real concern, then, is not that we weigh too much, but that we neither exercise enough nor eat well. Exercise is necessary for strong bones and both heart and lung health. A balanced diet without a lot of fat can also help the body avoid many diseases. We should surely stop paying so much attention to weight. Simply being thin is not enough. It is actually hazardous if those who get (or already are) thin think they are automatically healthy and thus free from paying attention to their overall life-style. Thinness can be pure vainglory (虚荣) .

Directions: In this section, you will hear 3 short passages. At the end of each passage, you will hear some questions. Both the passage and the questions will be spoken only once. After you hear a question, you must choose the best answer from the four choices marked A, B, C and D.
听力原文： To be addicted to cigarettes means that your body comes to need them. The addicted substance in cigarettes is nicotine. When people smoke the nicotine goes right into the blood stream and makes people feel relaxed. A smoker's body gets accustomed to the nicotine and if he stops smoking he feels nervous. Many smokers try to stop smoking but because of the addiction to nicotine they feel so uncomfortable that they often find it too difficult to stop.
Another reason is that people simply enjoy smoking and what it symbolizes. Having a cigarette for many people means taking a break. For some people smoking becomes part of certain social rituals, for example, the cigarette after dinner. Many people enjoy smoking because it gives them something to do with their hands. Reaching for a cigarette, lighting it and flicking the ashes are especially comforting in situations where a person feels tense.
Many people also like the taste of tar in cigarettes. However, it is the tar that causes cancer. While governments and health experts have tried to get people to give up smoking entirely, cigarette manufacturers have tried to keep selling them by producing cigarettes with less tar. Many people in western countries have welcomed these cigarettes since they find it hard to stop smoking but want to reduce the risk to their health.
