示例：Television
In China, almost every family has TV in their house. Television has become one of the most important parts of our life.
Some programs on TV are very educational and useful. We learn much knowledge on TV. For example, the news tells us what are happening all over the world; the ads tell us what things are good and cheap. The movies make our life colorful. But some programs are unhealthy for teenagers, and some ads are misleading . Watching TV too much is bad for our eyes, too.
We can change what is on TV, but we can choose what we watch.

在中国，几乎每个家庭都有电视。看电视已经成为我们生活中最重要的部分之一。
有些电视节目很有教育意义和实用价值。我们在电视上学到很多知识。例如，新闻告诉我们世界各地正在发生的事情，广告告诉我们什么东西物美价廉。电视使我们的生活多姿多彩。但有些节目对青少年来说是不健康的，有些广告是有误导性的。看电视太多对我们的眼睛也有害。
我们不能改变电视上的节目，但我们可以选择看什么节目。
