Does it have bad effect on us? And why?Discussion2.More and more people are using computers for information and entertainment. Do you think we will still need books and TVs in the future? Why or why not?
3.What are the possible disadvantages of having a lot of technology in our lives?Discussion: First of all, watching TV has the value of
giving people complete relaxation. After
working hard all day, people can forget
the pressures and challenges of work whe
-n sitting in front of TV. In addition to bei
-ng relaxing, TV is entertaining. As is kno
-wn to all, TV offers a variety of movies,
sports events and music to satisfy people’s
demands. Meanwhile, TV helps to widen
our knowledge and view by covering news.
However, TV has a bad effect on people,
too. For one thing, it is a big time waster.
Secondly, TV has killed people’s creativity
undoubtedly. While watching TV, people
become receptive and unquestioning. Finally
some TV shows are harmful to children,
whose mind may be filled with confusing,
misleading, and violent ideas. Besides, their
valuable time will be wasted.
