TV’s Influence On Our Daily Life

1)TV not only presents us a wonderful world, but also brings some changes to our daily life.

2)It is true that TV has the value of giving complete relaxation

3)Now we can see that TV has caused enormous problems along with its benefits.

参考答案：TV’s Influence On Our Daily Life
As is known, TV is penetrating deeply in people's daily life, without which our life will be incredibly dull and monotonous.it is believed that TV has a strong influence on teenagers in their thought and behaviour.
Admittedly,there is a trend that TV involves more and more violences which are commonly seen in its series and films.some people come to worry about the fact that the increasing amount of violent factors have led to some problems among the young.many youth are apt to imitate the violent conducts of those characters in TV,which has resulted in lots of deplorable accidents and tragedies.however,some people believe the TV itsself is not to blame but the society and the people who tend to amuse themselves in this way.
As I see it,I don't want to denounce either the TV or the society,i believe there is something knotty inevitably taking place in the evolution of human society.I think the bad impact on teenagers from TV programs is attributed to not only the programs themselves,but also the way people enjoy happiness,the conducts of commercial and educational walks.

第7题：

为何显卡TV输出的是黑白图像

这可能是因为制式不兼容而引起的问题。电视主要分为PAL、NTSC等制式，相应TV输出的显卡也有这两种制式。一般通过软件或显卡上的跳线可以设置输出的视频信号为PAL或NTSC制式，二者应匹配，画面才能正常显示。如果显卡只支持NTSC制式，而电视又只支持PAL制式，这时就无法欣赏到彩色图像了。

【分析处理】这很可能是因为制式不兼容而引起的问题。大家知道电视主要分为PAL、NTSC等制式，相应带TV输出的显卡也有这两科制式。一般通过软件或卡上的跳线可以设置输出的视频信号为PAL或NTSC制式，二者应匹配，画面才能正常显示。如果你的显卡只支持NTSC制式，而电视又只支持PAL制式，这时就无法欣赏到彩色图像了。
