    The Turn off (关掉) TV Week starts today. People who organize (组织) it say that TV is a bad thing. I' m not sure if they're 1 .

First of all, the organizers say that children today are in bad physical condition (身体状况) because they 2 almost all their free time in front of the TV. But a 3 of 10,000 American children aged 10 to 15 found no connection (联系,) between TV and physical health. Children who don't watch TV don't always do more 4 .

    Of course, there are some terrible programs on TV. 5 I don't think we should say no to TV. We 6 need to choose programs good for us ourselves. Another 7 that the organizers agree on （同意) is that TV stops us from talking with others. An American study found that parents in homes with no TV had an hour of talk with 8 children every day. In other homes, there was only 38 minutes of talk …… a week! That's bad. But TV can also bring people together and 9 to start a talk. Is there a better way to start a talk than by talking about, the latest popular programs?

    Turn off my TV? OK. But I also10 to turn it on when there's something good on.

      春天到了，大地复苏，花儿开放，整个大自然充满了生机，我十分喜爱这生机勃勃的春天，尤其爱春天里那绿油油的小草。
我家门前有一片空地，上面种着小草，它们是那样富有（生机、生命），春天一到，一下子就铺开了一片绿色的天地。细看，它们是嫩绿色的，水灵灵的，多么喜人！
       一阵风吹过，小草跳起了欢乐的舞蹈，时而舒展双臂，时而左右摇摆。它们像一群活泼的小女孩，天真可爱。这时你如果有空来欣赏一下，一定会叫你心旷神怡，乐而忘返。
       你别看小草这样（软弱、柔弱），可它永远不会向暴风雨低头。有一天，一阵狂风过后，突如其来地下了一场大雨。风雨过后，我赶紧去看那小草。呀！小草好像被折磨得奄奄一息了，有的歪歪斜斜，有的身子贴地。但我相信，它们是不会在暴风雨下屈服的。果然，小草又慢慢挺直了腰，尽管脸上还带着晶莹的泪珠！它们好像在骄傲地说：“你看，我们是多么顽强啊！
      小草，没有鲜花那么娇艳，没有白杨那么（挺拔、挺立），可是它的生命力是多么（顽强、坚强）！人们说“疾风知劲草”，小草是当之无愧的。
