I’m writing the letter to share my ideas about how to improve the environment.I find that the rivers in our city are very dirty. Many factories put waste into the rivers and humans also throw rubbish into them. Besides, there are more and more cars on the road. It not only makes the air be badly polluted, but also makes the streets noisy.To protect the environment, I would like to give some advice. First of all, the governments should close down theSample writing:factories that pollute the air and water. Second, I suggest that the governments should organize some activities to teach people the importance of environmental protection. Last but not least, people are supposed to be fined for littering.In a word, I hope my suggestions will be useful. If everyone takes part in environmental protection, our city will be better and better.Yours sincerely,Li HuaSample writing:Peer-editing项目 标准 自我评价 同伴评价结构（3分） 段落合理 （2 分）衔接自然 (1分)内容（8分） 要点1:当今的环境问题（2分）要点2:你的建议（3分）要点3:呼吁（1分）拓展合理 (2分)语言（3分） 词汇丰富 (1分)句法正确 ，语言优美( 2分)卷面（1分） 书写工整（ 1分）v. – n.pollute —act —protect —inspire —build —create —n. – adj.fame —wood —science —health —south —care —pollutionaction/actorprotectioninspirationbuildingcreativitywoodenscientifichealthysoutherncarefulfamous1.
