   One possible version

   Dear Sir/ Madam,

Environmental problems are becoming 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 governments should 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 become better and better.

成功之处：

本节课从提问学生写作中最大的困惑入手，引出本节课的主要教学目标，在写作中学会构思和使用连词。通过比较两篇学生的英语习作，让学生认识到连词在英语写作中的重要性。通过分析一篇学生的范文，让学生了解怎样去运用关联词，怎样去组织一篇文章，最后让学生根据提供的材料完成一篇习作，并互相评价，修改。我认为本节课在以下几个方面处理得较好：

  1.课堂教学组织严谨，教学各个环节环环相扣，很流畅，由提问引出主题，通过比较学生习作认识到连词使用的重要，通过分析学生习作教学生学会怎么运用，最后进行实践。

  2.学生书信写作练习的设计比较新颖。

　3.考虑到本校学生生源的实际情况，写作任务经过了层层分解，从文章结构的构思，到语言的组织，时态的运用等给足了提示，使写作任务的难度降低了，让大部分学生都可以完成写作任务

不足之处：

因时间关系，学生写作的时间不太够，还有一小部分学生没有按时完成写作任务。习作的点评也不够时间处理，只点评了一篇习作，如果能找各个层次的学生习作进行点评就更好。

改进措施：（具体落实存在问题的内容、时间、方法）注重课堂同学间批改，内化英语写作技巧学生习作批改对教师来说是一项大工程，工作量大，且繁杂，并且不妨尝试师生共评、生生互评、师生互评等作文评价方法。教师应该把评价定位在激励学生的进步上，通沟和协商、理解和激励使评价对象最大限度地接受评价结果，从而大大地提高写作的教水平。课堂批改评价方式有：①抓典型，课堂面批。②同伴批改。③教师批改。实践证明伴批改能够帮助学生提高语言意识，内化英语写作技巧，更能为学生所接受。
