When you are watching TV, you will notice that more and more famous stars make the ads on TV. Many people believe them because they are famous. But have you ever thought if the ads are real or not?

In the past few years, lots of stars have been on TV or newspapers as spokesmen(代言人) of some products(产品), such as Sanlu Milk and Haojixing Study Machine. People spent much money on these products, but at last, many of them were not like what the stars said. More and more people are very angry with the famous actors for making the ads after the accident of Sanlu Children Milk.

What are the public’s ideas about the famous people making ads on TV? Do you agree that the famous people should take responsibility (负责任) if the products have any problems? A research shows that about 36% think it wasn’t the famous stars’fault(过错),but they all think famous stars should give out the money they got from the ads or the charity(慈善机构).More than34%think the famous stars must take responsibility.They are dishonest and lose themselves in the public.

So we should be more careful when we buy things advertised by the stars. We must find what these things are really like instead of only listening to what the stars say.
