The appeal of advertising to buying motives can have both negative and positive effects. Consumers may be convinced to buy a product of poor quality or high price because of an advertisement. For example, some advertisers have appealed to people’ s desire for better fuel economy for their cars by advertising automotive products that improve gasoline mileage. Some of the products Work. Others are worthless and a waste of consumers’ money.
Sometimes advertising is intentionally misleading. A few years ago, a brand of bread was offered to dieters (节食者) with the message that there were fewer calories (热量单位,卡路里) in every slice. It turned out that the bread was not dietetic (适合节食的) , but just regular bread. There were fewer calories because it was sliced very thin, but there were the same number of calories in every loaf.
On the positive side, emotional appeals may respond to a consumer’ s real concerns, considering fire insurance. Fire insurance may be sold by appealing to fear of loss. But fear of loss is the real reason for fire insurance. The security of knowing that property is protected by insurance makes the purchase of fire insurance a worthwhile investment for most people. If consumers consider the quality of the insurance plans as well as the message in the ads, they will benefit from the advertising.
Each consumer must evaluate her or his own situation. Are the benefits of the product important enough to justify buying it Advertising is intended to appeal to consumers, but it does not force them to buy the product. Consumers still control the final buying decision.

After a day’ s hard work, we need some sleep. During the sleep, the fatigue(疲劳) of the body disappears and recuperation(恢复) begins. The tired mind gathers new energy, and the memory improves.
Some adults require little sleep; others need eight to ten hours in every twenty-four hours. Infants (婴儿) sleep sixteen to eighteen hours daily, the amount gradually diminishing as they grow older. Young students may need twelve hours ; university students may need ten. A worker with a physically demanding job may also need ten, whereas an executive working under great pressure may manage on six to eight. Many famous people have little sleep. Napoleon Bonaparte, Thomas Edison and Charles Darwin apparently averaged only four to six hours a night.
Whatever your individual need, you can be sure that by the age of thirty you will have slept for a total of more than twelve years. By that age you will also have developed a sleep routine: a favorite hour, a favorite bed, a favorite position, and a rule you need to follow in order to rest comfortably.
Investigators have tried to find out how long a person can go without sleep. Several people have reached more than 115 hours--nearly five days. Whatever the limit, it is absolute. Animals that kept awake for from five to eight days have died of exhaustion. The limit for human beings is probably about a week.
