Dear Mr. John,
     I'm Li Yuan, the leader of the Student Union of Yu Cai Middle School Middle School. I sincerely hope you can set aside some time for our English speech contest and be a judge.
     The contest, the theme of which is "Man and Nature", will be held in the Room 501 from 2:00 to 5:00 on the afternoon of June 15. What's more, there will be 10 students taking part in it. I'm sure it will be a great success if you can give us some precious remarks after the contest. I would appreciate it if you could accept my invitation.
     I'm looking forward to your reply.
