听力原文:M: Hi, Jane, you are my best friend, I want to run for the monitor of our class, but I don't know how to let others realize that I am the best candidate for it. W: It's not an easy job at all. M: Thanks a lot. W: I'm just kidding, Robert. In fact, you will win it easily, as long as you tell them how well you did in junior middle school. M: How can I do that? Shall I come to visit all of my classmates and tell them? Is it possible? W: Come on, I think, it may be better if you write something about yourself and post it in our classroom, so that every body can see it. M: That sounds good. But everyone puts up posters. What can we do that's different? W: Oh, I just forgot it. Today is Paul's birthday, and he will invite the whole class to his party, so you can make full use of that. M: That is a great idea. W: And I strongly advise you to introduce your plan for the year. M: That is a great idea. But I think I'd better come up with a speech pretty quickly. How about if I write it later and show it to you after it's done? W: Fine, I'll see you then. M: Thanks for all your help. (20)
