How to build an economized society

 Our government is aiming to build an “economized society”. I think it is every citizen’s duty to work hard to achieve this goal.

   To build an economized society, we must keep the following points in our minds. Firstly, make sure that the lights and the electric fans are turned off when there is no one in the room. Set the room temperature at above 26 ℃. Remember to turn off the computer when you are not using it.

Secondly, try to form the habit of turning off the tap after it is used. Use basins when washing faces or vegetables. Thus the water can be used again to clean toilets or water flowers. Thirdly, it will be good enough to use a basket instead of plastic bags when you go to the market. As we know, a basket can be used many more times.

In a word, we should try our best to build an economized society.

肥胖已经成为危害人们健康的严重问题，中小学生的肥胖趋势更为明显。你们班对此展开讨论。根据不同的观点，写一篇100词左右的短文。

    要点提示：1．节电：及时关闭灯、电扇、电脑等；    2．节水：随手关水龙头、废水利用等；

Dear Mr. Wang，
　　We’re so pleased that you are willing to share our views.
　　In the course of the general revision， what we need is solid foundation. As you know， we didn‘t learn well enough in the first two years， so please slow down and make sure we have really mastered something. Besides， we need a little more time to think for ourselves. As for those important points which also make us confused， would you please give us more practice in case we forget？ Meanwhile， we need your instruction， for example， in how to write in natural English. I still have another request： assign us less homework in order that we can do it more efficiently.
　　By the way， we often feel frustrated， which has a very bad effect on our study. We would appreciate it if you would give us some encouragement from time to time.

      国家正在提倡“节约型社会”，你将以“How to build all economized society”为题向《2l世纪报》
