Dear Tom

　　Thank you for your invitation next week. I’m afraid that I can’t come. I have a really busy week. Monday to Friday, I will study at school, the middle exam is coming next week, I must study hard for my lessons, or my mother will be angry with me. She is so hard on me that I have no time to play. On Saturday morning, I will do my homework. In the afternoon, I .am going to play soccer with my classmates, because we have a match, and we were defeated last match, we must win this match, or we’ll be pushed out. On Sunday morning, I have an English lesson. And in the afternoon, I have to go to see the doctor, so I can’t come maybe next time.

　　I hope you have a good time at your birthday party.

　　Best wishes!
