Television plays a very important role in people's lives.It's a wonderful source of information and one of the best ways to spend free time.Television viewing is the most popular leisure pastime.It's not surprising,because TV channels show a great variety of programmes:feature films and comedies,soaps and police series,concerts and talk showa. Television is a reflection of the modern world.It gives you an opportunity to travel all over the world,to see different people and to learn about their customs and traditions.Television keeps you informed about the rest of the world.It also helps to escape from our everyday problems.A lot of people usually relax watching soaps.Their story lines are entertaning,but ofter unbelievable.I don't think that they show life realistically.But to many people,the characters in the TV serial have become more important than real people. Of course,not everything show on TV is made in good taste.There are badly-written programmes that contain unnecessary bad language and violence.Another thing I would like complain about is the amount of smoking in the films that are shown on TV.Smoking is ofter show as a very "cool" thing to do,making young people take up smoking themselves. Many people admit that the quality of television could be better.One reson for the poor quality of programmes is advertising.Not all people like watching commercials.They find ads silly and boring.But I am not against commercials on TV,because television companies get most of their money from advertising. Some people say that television is a terrible waste of time.Of course, there are TV addicts who can't drag themselves away from the box.But If we watch TV for an hour a day,to find out what is happening in the world or to relax, then television is really useful.So I thing we should not blame the TV for the bad effects it has.We must know how to make he best use of it.Прошу срочно перевести и если не сложно сделать пересказ из 10 предложений!!!
