【答案解析】[范文]Dear John.
I am going to a concert next Saturday, I really want you to join me to attend the concert.
The concert will be held at 8 p. m., next Saturday, May 11th in the new concert hall. A lot of symphonies will be played, including my favorite Nine Symphony of Beethoven. To avoid traffic jam,we should leave home two hours before the start of the concert. The acoustics of the new concert hall are excellent, so we should switch off the cell phones to enjoy the concert. Formal dress code is required on this occasion.
I hope you could join me and appreciate classic music with me. Looking forward to your reply.
Yours sincerely,
Li Ming
