Dear Mr Jenson，
I am writing on behalf of① the school's Student Union.As you may know, we are running a schoolwide public speaking competition, and the final will take place at the lecture hall on 10 May (9 am－12 pm)．I am writing to ask whether you would be willing to help us judge the final competition.
本部分直接说出邀请的目的。
Since March, we have already had two rounds of the competition, with more than 100 students.Now we have 12 students left for the final.The topic② of the final speech is “Education for Innovation③”．Students have to give a fiveminute speech on④ the topic in English.
During the final round, as a judge, you would be responsible for⑤ listening to all the speeches, noting down any positive or negative aspects for each one.Competitors⑥ should be judged on their pronunciation, clarity⑦ and fluency⑧， and also progression⑨ of ideas and audience engagement⑩.Then you will discuss your notes with three other judges, and come to a decision about? who comes first, second and third.
Would you have time to attend a short meeting at the Student Union Room at 4 pm on 8 May so that we can introduce you to the other judges and discuss the details? We would not take up? too much of your time.
本部分具体介绍邀请活动的时间、地点、方式、注意事项等。
I sincerely ? hope you can come.If you have any questions, please do let me know.
本部分表达期待。
Yours sincerely，
Zhao Zheng
President, Student Union,
