It is not easy to find a public place without advertisements. We can see them everywhere, especially in newspapers or on TV. It’s true that ads are playing a more and more important part in our daily life. They tell us some information about new products and help us to decide what to buy.
‘Each coin has two sides’-----Everything has its advantages and disadvantages(优势和劣势).Ads also have disadvantages. For example, some of the factories hope to win a big market for their products. They are so dishonest that they don’t tell the truth about their products. They try their best to make people believe that the advertised（打广告的）products are good. But in fact they are of poor quality(质量). Many people are cheated(欺骗) by the dishonest ads. So people often buy what they do not need.
Where can ads be seen(被看到)?
