Dear Bob,
How is it going?
An English Culture Festival will be held in our school. All of us students do hope that you could come and join us.
The activity will begin in the Lecture Hall at 14: 30 this Friday ant last about 3 hours. We've prepared many programs for it, for example, English songs. What's more, some students will perform plays in English.
As you know, many students in our school have difficulty in learning English well. So when the performance finishes, it would be very nice if you could give a talk and provide us with some practical advice.
Looking forward to your reply.
Yours,
Li hua
