本单元的写作话题是节约资源、节约用电。 “地球一小时”活动是世界自然基金会于2007年为应对气候变化而发起的一个全球活动，号召人们在“地球一小时”活动当天晚上8时30分至9时30分关闭不必要的电源。在今年“地球一小时”活动日到来之际，你想为学校的宣传橱窗写一篇短文，倡议同学们节约用电。同时你还要说明电能的来源：火电、水电、风电、核电等。要求：80词左右。
要点：1.电的重要性； 2.用电现状； 3.如何节约用电； 4.安全用电等。
◆审题
我们在确定写作中心后，就开始寻找写作素材。既可以从课本Unit 6中找出相关的内容，也可以结合生活实际，找出有关用电的现状、用电安全以及如何节约用电的内容；然后再根据所给的英文提示(相当于提纲)，形成短文。
1.首先要说明电的重要性以及列举用电现状，再引出如何节约用电以及安全用电，最后用一句总结性的话结尾。
2.注意时态。由于是介绍一般性的事物，所以全文应以一般现在时为主。
3.初步成形。可以根据给出的中文提示先用简短的句子表达出来。
4.连句成文。根据写出的句子适当扩展，使文章通顺、流畅。

Saving electricity
Electricity is becoming more and more important. There are different ways of producing electricity. It usually comes from coal energy，water energy，wind energy or nuclear energy. Part of electricity comes from coal energy. It has a bad influence on the environment. And there is less and less energy in the world. Electricity makes our lives more convenient. So we should know how to save electricity and how to use it safely.
First of all，we should value the energy and good environment the Earth offers us. When we leave the house and classroom，we should switch off the lights in time. Besides，we must be careful with electricity.We can’t touch it with wet hands because we may get an electrical shock. More importantly，we should know how to use the electrical appliances properly.
If we don’t take action now，we will not have enough energy in the future. Please save electricity! And use electricity properly，everybody!
