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 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 the traditional Chinese painting，which，together with her active personality and perfect spoken English，will help make your activity a success．
Sorry again for any inconvenience caused by my absence．
