Dear Tom, Thank you very much for your invitation. I’d like to accept it and take this opportunity to introduce the traditional Chinese painting to foreign friends, but I’m sorry to inform you that I can’t. The reason is that I, together with my classmates, am busy preparing myself for the coming final examination. I strongly recommend my friend Mary, who is the most suitable choice to take my place next week. She began to learn painting at an early age and has a good knowledge of traditional Chinese painting, which, combined with her active personality and perfect spoken English, will help make your activity a success. Sorry again for any inconvenience caused by my absence. Best wishes. Yours sincerely, Li Hua

本文是考生非常熟悉的书信，首先要审好题，本文属于半开放性的作文，要点给的很模糊，要求考生有较多的个人发挥。在写作时要注意使用高级的词汇如recommend，inconvenience等。同时也要注意使用合适的连接词，和高级句式如定语从句，状语从句，强调句等等，让文章更有层次。
