读写任务

阅读下面的短文，然后按照要求写一篇150词左右的英语短文。

     It is common to find advertisements on TV or radio.Most advertisements are very short for people to

remember.Nike, for example, has a simple slogan used all around the world: “Just do it”.

Advertisements often use funny situations as well.

    Advertising gives useful information about which products to buy.But modern advertising does more

than give news about products and services.Today's advertisements try to get consumers to buy certain

brand s.Writers of advertisements are so skillful that they can sometimes persuade a consumer to wear

a certain kind of clothing, eat a special kind of cereal (谷类食物), or see a movie.Consumers might want

a product even if they did not see or hear advertisements for it.

     For example, you probably do not need the newest cereal in the supermarket.There are probably

many cereal brands on your kitchen shelves.You may not have space on a shelf for another.But if you

see ads about a new cereal that is extratasty and has a free prize in the box, you may want it.

     To be effective, advertising must be exciting, entertaining, or provide some pleasure.The secret of

writing good advertising copy is to offer a good idea as well as a product.The idea is what the ad is really

selling.One example is an ad that says eating a cereal will make a person do well in sports.That cereal

brand may sell better if consumers think it offers strength and energy.
