TV is popular in modern times, and most of us spend a lot of time enjoying a variety of TV programmes every day. What benefit does TV bring to us? Does it have any bad effect on us? And why?Discussion First of all, watching TV has the value of
giving people complete relaxation. After
a busy day, people can forget the pressures and
challenges of work when sitting in front of TV.
In addition to being relaxing, TV is entertaining.
As is known 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 the latest 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. To complete A1 and A2 on page 102 of the Workbook.
