答案：
Dear Mr Wang,
I’m very excited to write to express my thanks to you. I am now a freshman of Beijing University, which I have been dreaming about. Mr Wang, I still remember the days when you taught me English. My English has been improved greatly because of your creative work. However, at one time, the pressure of examinations, too much homework and the high expectations made me depressed. I was tired of the warning that if I didn’t do my best, I wouldn’t have the chance to go to college. Thanks for your encouragement; if not, I wouldn’t have realized my dream. And now I really understand you. I wish more and more of your students could go to their ideal colleges. Are you still so busy? How I miss you!
Look forward to hearing/Hoping to hear from you soon.
Yours,
Li Hua
题目分析：这是一篇书信类作文，假设你叫李华，现是北京大学的一名新生。请你根据以下提示，给你中学的英语老师王老师写一封感谢信，表达对他的爱戴和尊敬，所以要用第一人称来写。需要写的内容已经给出，但是写作时不要仅仅对要点进行生硬的翻译，而是要添加些内容，使文章看起来更充实，要组成一篇通顺连贯的短文。需要注意紧扣文章主题，给出的要点都需要包括，缺一不可。写作时注意准确运用时态，上下文意思连贯，符合逻辑关系，不能出现文章脱节问题。尽量使用自己熟悉的单词句式，同时也要注意使用高级词汇和高级句型使文章显得更有档次。同时注意要求的字数120左右，不要太多也不要太少。
点评：本文属于书信类作文，动笔前，一定要认真分析要点，理解要点要表达的含义，不能遗漏要点，跑题偏题。平时除了加强词汇积累，写作联系以外，还可以适当记忆一些类似的范文，这样在考试中可以起到事半功倍的效果。
