Dear Mr. Brown，

  I am writing to express my deepest gratitude for the money and books you sent me. I could not have returned to school without your help. Thank you so much.

I have been working hard since I went back to school. I have made great progress in my studies with the help of my teachers. They often praise me and encourage me. But for your help, I might have left school and couldn’t have got such a good education. I have made up my mind to study harder and make greater progress.

How are you getting on with your life and work? I would like to meet you in person, but I have no opportunity to do so. Would you please send me a photo of yourself?

Thank you again for your generous help and best wishes!

Yours Sincerely，

Li Hua　

题目分析：考查提纲类书面表达：这是一篇提纲类作文，我们需要用正确的英语把给出的要点表达出来. 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。本作文中给出的要点比较具体,故需要准确表达.写作时注意准确运用时态，上下文意思连贯，符合逻辑关系，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。特别注意在选择句式时要赋予变化。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。

【亮点说明】范文中出现一些常见的短语：returned to 返回某处； made great progress取得进步； with the help of 在某人帮助下；made up my mind to下定决心做某事； getting on with与某人相处如何； have no opportunity to do 没有机会做某事。I have been working hard since I went back to school.这句话中考查现在完成时。But for your help, I might have left school and couldn’t have got such a good education.这句话中运用对过去的虚拟语气。I have made up my mind to study harder and make greater progress这个句子运用两个比较级，前后相互呼应。
