Dear Alice, 

      Thanks a lot for your invitation. I'm sorry I am really busy this week. On Monday,

I have to study for the geography test. On Tuesday, I'm having a piano lesson. On Wednesday,

I have to babysit my brother. And I have to help my mother with the housework on Thursday.

On Friday, I'm visiting my grandma. Please call me after the match and tell me about it.

                                                                                                              Yours, 

                                                                                                            Wang Lin
