Answer 1

Dear Paul，
  Thank you very much for your invitation．
  I'd love to accept it and take this opportunity to introduce traditional Chinese painting to foreign friends，but I'm sorry to inform you that I can't．My grandpa is seriously ill in hospital and I have to look after him．As for the introduction speech，I strongly recommend my friend Anna，who is the most suitable choice，to take my place next Sunday．（高分句型1）She began to learn painting at an early age and has a broad knowledge of traditional Chinese painting，which，combined with her active personality and perfect spoken English，will help make your activity a success．（高分句型2）
  Sorry again for any inconvenience caused by my absence and all the best wishes to you．（高分句型3）
                                                                                                                                                                                                                                      Yours，
                                                                                                                                                                                                                                       Li Hua
