Topic:
Television is one of the most important technological developments in the 20th century. It has changed people’s lives. Have all the changes been positive?
 
Sample:
Television has been regarded as one of the most important technological developments in the 20th century. 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. In my opinion, its disadvantages outweigh its advantages.
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.
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 modern families. Now many children even have their own TV in the bedroom so they spend very little time with their parents or brothers and sisters. Some people might argue that this helps young people to become independent, but I think this is a negative effect because they will be unable to communicate effectively or relate to others emotionally.
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. Advertising, too, can have very negative effects. Furthermore, TV is sometimes used to deliberately misinform people, for example when it is used as a propaganda tool by governments.
To sum up, I feel that, overall, there are strong positive effects of TV in terms of its educational role, but it has in many ways altered people and families in a negative sense.
