One possible version Dear Sir/ Madam, Environmental problems are being more and more serious all over the world.With the development of the society, there are too many cars on the streets in our city. Cars have made the air unhealthy for people to breathe. Black smoke and poisonous gas are given off by factories. Factories also put waste into the river. And wherever we go, we can find rubbish.Now more and more people have realized these problems. I think that governmentsshould close down the factories and develop laws to stop people from driving cars every day. I suggest everyone in this town should help to clean up the river and the streets. We should call on everyone in the town to throw rubbish in the dustbins.I hope the problem will be solved in the near future and our home will bee better and better. VII. HomeworkFinish your writing. We have only one earth.Unit 13Were trying to save the earth!教学反思25团中学 徐铭敏通过这节课我让学生知道环保的重要性,以与我们每位学生如何去做力所能与的事情来保护我们的地球,同时学生将我们整个初中的重点句型熟练运用其中,如Were trying to save the earth! The river used to be so clean.The air is badly polluted.：同时也通过口语表达,写作运用的途径,巩固了生词,如noise pollution air pollution water pollutionput sth. to good use, pull down,等等.基本完成了我预期设计的任务.但还有以下问题：1. 学生在使用建议句时有一些语法错误,如had better do, Why not?动词不定式没有省略to.2.写作当中,有的学生没有一个结尾,如,We must take action.等.3.有的学生对生词掌握的还是不够熟练.应作如下改进：1.归纳建议句的用法.2.拿一个比较典型的问题作文下节课再加以改正.7 / 7
