参考范文 Twenty years ago,most Chinese did not know what a TV looked like;whereas today,TV viewing has become almost an indispensable part of family life.In fact,people enjoy it for good reasons.Above all,TV is a convenient and efficient medium for obtaining knowledge and information.Mysteries of science and miracles of technology are exposed through popular science programs;beautiful natural scenefies and diversified traditions all over the world fascinate a good number of TV viewers;news stories and social phenomena are recounted and analyzed incisively….No means of mass media other than TV brings them more vividly to people.Besides,TV viewing is a cheap means of entertainment.Even if your wallet is thin,turn on TV and your dreams come true.You can travel around the world.You can watch films,plays,operas,and so on without buying a ticket.Neither do you pay for news reports,sports games,or soap operas.In a word,TV is both ready to serve the viewers and money-saving. But every coin has two sides.TV is of no exception.For many people,TV viewing can be addictive.Many people turn on TV the instant they arrive home in the evening and do not turn it off until before they fall asleep late into night.Most of them complain that TV has taken up too great a part of their spare time.Furthermore,too much violence and sex will inevitably have bad effects on children,who are at the impressionable age,and may very likely follow suit.No doubt,negative effects such as these should be dealt with seriously. Such being the case,shall we continue to watch TV or throw it away?My personal opinion is that we should certainly make good use of this technological miracle.We should watch TVprograms which really interest us and which are instructive.At the same time,individual viewers should determine what is worth watching and what is simply trash,and make intelligent choices.That is to say,you are the one to decide how much treasure or trash is conveyed to your house through the TV screen.
