Section II 重组下面的段落

6. Certainly TV can be a powerful educational tool. People can learn about situations and problems far away, and begin to understand different cultures. Many informative documentaries about nature, news, and social issues are made now, and these can stimulate people to action. People in isolated areas can know for themselves what is happening in the world. This gives them the power to make their own decisions and form their own opinions.

7. In my opinion, television is the most important technological development. Nowadays almost everyone in the world has access to TV. Television has caused significant changes in family life and education. Some of these changes have been positive while others have been negative.

8. However, the changes have not all been positive. Before television was widely available, families spent more time together talking and playing games. They seemed much closer to each other than modem families.

9. To sum up, I feel that, overall, there are strong positive effects of TV in terms of its education role, but it has in may ways altered people and families in a negative sense.

10. Also, the fact is that people waste a lot of time watching poor quality programs which do not have a positive influence. People get a bad impression of the real world from such programs. Furthermore, TV is sometimes used to deliberately misinform people; for example when it is used to as a propaganda tool by governments.
