17. 根据下面所给题目写出一篇不少于80词的短文。写作题目：On television 参考范文： Television now plays such an important part in so many people’s lives that it is essential for us to try to decide whether it is a good thing or a bad one. Clearly, television has both advantages and disadvantages. Television keeps one better informed of what is going on in the world. The most distant countries, the strangest customs and the most attractive scenes of nature are brought right into our room. Yet, its down side is not to be ignored. The main problem with TV has been its effect on young people, who are too young to decide which programs are the right ones for them. As we know, quite a few commercials and harmful programs tend to influence them negatively. To conclude, television in itself is neither good nor bad. It is how we use it that determines its true value.
