单选题 Listen to the conversation and circle the appropriate letter.
单选题 The homework should be presented in the form of __________ .
【正确答案】 A
【答案解析】STUDENT: Excuse me, Sir. Yesterday you asked us to say something about the National Energy Program, but you didn’t say how to finish it. TEACHER: Oh. I forgot that you are all freshmen and don’t know the traditional form of such kind of homework. It should be presented by PowerPoint, and submitted by groups. STUDENT: You mean that we should make PPT to illustrate our points? TEACHER: Yeah. You know projectors have been installed in every classroom. So we don’t need any printing papers or handwriting. Since it is a type of group work, you need to divide the work reasonably. STUDENT: I see. Then what’s the maximum number of members that a group can have? TEACHER: The number should be no more than 7, and no less than 4. STUDENT: OK. Is there any requirement for the presentation time? TEACHER: Well. After the presentation, I think most people will have a lot to talk about. So a presentation should run no longer than 15 minutes. STUDENT: Wonderful. Thank you, Sir. I must find my group members right away and make some preparations for the presentation. TEACHER: Yeah. Good luck for you, and don’t forget to notify other students about the information.
