听力原文:M: Dr. Wilson, can I tall to you for a minute? W: Sure, Fred, what is it? M: I'm worried about my grade in your English class. I really want an 'A', but... W: I see. Well, it might be hard for you to get an 'A'. So far you have a 'B' average. You would need a 97 or 98 on your final exam to get an 'A'. Do you think you can get that high a score? M: Probably not. The problem is I have to have a 'B' average in all the subjects to get the prize from our government, or I'll have to find a part-time job. I'm afraid it is difficult for me to put all my heart in my study if I have to work in my spare time. I'll probably get an 'A' in history and a 'B' in math, but I'll get a 'C' in chemistry. W: That is a problem, isn't it? You'll have to have an 'A' in English to get a 'B' average. M: Yes, but it doesn't look very good for me right now. W: I gave two less tests this term than I usually do. That might have changed your grade a little. Maybe I'll give everybody a chance to write a composition in English, then you'll have a good chance to get an 'A'. M: That would be great. I'll try my best. Thank you very much. (8)
