Today more and more advertisements are seen on the TV screen. It's difficult to find a program without insertion of ads on TV. Food, clothes -- everything you can think of --are presented on television. Occasionally, we can also see some public welfare ads, appealing to people to respect the old or to protect the environment. In general, there are two main reasons leading to the prevalence of commercials on TV.

As far as I am concerned, I am in favor of TV ads because some of them are interesting and informative. But there is no denying that some of them are tedious and not trustworthy. Therefore, I think it is really high time that the TV stations strengthened the control of advertisements and made them more attractive.

如今，越来越多的广告出现在电视屏幕上。在电视上很难找到一个没有广告的节目。食物、衣服——你能想到的一切——都在电视上呈现。偶尔，我们也可以看到一些公益广告，呼吁人们尊重老人或保护环境。总的来说，有两个主要原因导致电视广告的流行。

就我而言，我赞成电视广告，因为其中一些广告很有趣，信息量大。但不可否认的是，其中一些是乏味的，不值得信赖的。因此，我认为电视台是时候加强对广告的控制，让它们更有吸引力了。
