　　Dear Tom，

　　Thank you very much for inviting me to your birthday party。 I‘d love to go but I can’t。 My parents are out on business。 They are coming back next month。 And now I have to look after my grandma because she is ill in bed。 And I also need to study for my coming English exam。 I‘m very sorry but I can’t go to your party。 Thank you for asking me。 I hope you can have a good time。
