读写任务(共1题,满分25分)

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。

There is no doubt that watching television can influence the way that people behave. Moreover, it seems that people are spending more and more time watching some sort of visual entertainment, whether it is television, a video tape or a DVD. Therefore, the effects of visual media cannot be ignored.

One obvious effect of these media is that watching them induces people to buy certain products. Television advertising is widespread and, nowadays, even movie theaters permit advertisements. Another way TV and the movies affect people is that they give people either a    broader view of the world or a distorted one, depending on what type of program they watch.         Those who watch news and educational program can learn many new things while those who watch primarily entertainment shows may come to believe that most people in the world possess   great wealth and good looks. It may make them become dissatisfied with their own lives. Finally, perhaps the most susceptible viewers are children, who may be unable to tell fact from fiction and   may try to imitate acts that they see on TV or in the movies. And this is just what most parents and our society are worried about.

With the every-increasing popularity of video entertainment, we must pay attention to these effects.
