电视商业广告已经成为了我们生活的一部分。写一篇短文，阐述以下你对电视商业广告的看法

I think TV commercial ads have both advantages and disadvantage.

To begin with, they are good because they can popularize the latest products. For example, if some people want to buy a digital camera, but they have no idea about which brand is the best and where to buy it. They may just find out relevant information about it by watching TV ads. But , of course, TV commercial ads are bad because some of them are misleading. For example, some ad about an English training course says “Come and join us. You can learn how to speak English within 40 minutes.”

To conclude, people should be very much careful about TV commercial ads.
