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.

It can be inferred from the passage that a smart consumer should（）

A. think carefully about the benefits described in the advertisements

B. guard against the deceiving nature of advertisements

C. be familiar with various advertising strategies

D. avoid buying products that have p emotional appeal

----Thank you for your help.   ----_____.

Your daughter has finally reached the age of 18, and you think perhaps your job will finally get a little easier. That could be wrong thinking - as the parent of any 18-year-old will tell you.  Learning to cope with an ungrateful 18-year-old daughter takes patience, understanding and time.

_______ When she was a little girl, she wanted you to be involved（参和） in everything of her life from her daily activities to her friends. This is' no longer the case. She's a grown woman who needs her own personal life. Comment（评论） on her choices only when asked to do so - especially if you want to say no to her.

Allow her to make mistakes. No parent wants to see his or her child fall, but the days of protecting her all the time are at an end. Unless（除非） you see a train coming, let her fall when she makes poor choices. It will enable her to grow past the ungrateful "know it all" stage.

Encourage dialogue whenever you can, rather than planning talks. She's more likely to open up to you when talking over something trivial (琐碎的). Anytime she wants to talk, become a willing listener in the conversation. You never know when a deeper, more important conversation will develop.
