Dear Mr Smith，
If you have no other plans for Sunday，June 15，would you like to come to our dancing party?
All the students of our class are coming. Mr Li，our dean，is also joining us. And we shall be very pleased if you could manage to come，too.
The party is at 7 p. m. in the school hall. We shall expect you then if we do not hear from you to the contrary(回绝).
Yours sincerely，
Li Ming
