写作思路：从写信给英语老师罗宾的写作目的、中心主旨入手，以使文章中心思想鲜明、深刻地表现出来，正文：
Dear Robin teacher ,
亲爱的罗宾老师，
I am writing to you to express my thanks for your help in learning English and speaking English.
我写信给你，对你在学习英语和说英语方面的帮助表示感谢。
During these days in your class, I have learned much from you and it is very helpful to me. Firstly, you let me know what is the west thinking pattern—straight thinking pattern.
在你的课上，我从你身上学到了很多东西，这对我很有帮助。首先，你让我知道什么是西方思维模式——直思维模式。
And, I think, it is very important to understand the west’s thoughts. As you know, this can help me with my examination and interaction with foreigners.
而且，我觉得，了解西方的思想很重要。如你所知，这可以帮助我的考试和与外国人的互动。
Secondly, I have got enough confidence in speaking in English from your class and it took me a long time to gain this confidence. Now, I always express my ideas in English as possible as I can. It’s great to do that.
其次，我已经从你们班获得了足够的英语口语自信，并且花了很长时间才获得这种自信。现在，我总是尽可能用英语表达我的想法。这样做很好。
The last not the least, I find that learning English is not an boring thing as before and I’m interested in studying English which was just a necessary task to pass examinations. Reading, listening or speaking all become interesting and I really enjoy it.
最后同样重要的是，我发现学习英语并不像以前那样无聊，我对学习英语感兴趣，这只是通过考试的一项必要任务。
Above all, I want to say thanks again to you. And thank you for your time.Good luck.
阅读、听力或口语都变得有趣，我真的很喜欢。最重要的是，我想再次感谢你。谢谢你抽出时间。祝您好运。
