9-1 邀请➕ 说明（13英一）

Dear Professor Sky,
It is so great to recall the last successful English Speech Contest in which you were one of major judges. Today, I, on behalf of the Students’ Union, am writing for the purpose of inviting you to be the judge again for this year's contest.
We are quite grateful for your hard work in teaching and it is your warmhearted help that enables so many students to build up interest in English. Thus, compared with last year, more youngsters, this year, will participate in this contest. Since you focused much eyesight on teaching speech during the past three years, it is appropriate for you to give contestants professional advice. The contest is going to start in the Center of Students’ Activities at 18： 30 on May 21.
We are looking forward to your favorable reply at your earliest convenience.
Yours sincerely
Li Ming
