Why does the student go to see his professor?Questions 1 through 5. Listen to a conversation between a student and a professor. M: Professor Nolan, do you have a few minutes? W: Sure, Jason. What can I do for you? M: It’s about the grade on my paper. Um, the grade is too low, I mean, it’s lower than I expected, so I was wondering if I could rewrite it to raise my grade. W: I’m afraid it’s too late for that. In fact, it’s nearly time for the next paper, which is due at the end of next week. Instead of worrying about just one paper, I think it would be better if you focused on the rest of the semester. Study hard and concentrate on what you can do during the remaining eight weeks. M: I already study hard for this class. I spend almost three hours a day on the reading. What’s your advice—I mean, is there anything I can do for extra credit to raise my grade? W: You’re doing the reading, and that’s good, but maybe you need to do something different, to make the most of your study time. Instead of always reading alone, I advise you to study with other people. Organize a study group with other people from the class. Reading and discussing philosophy with others can help everyone understand the most challenging material. You won’t always think alike, but that’s often the best way to learn. You get to hear how others interpret the material, and it’s an especially good way to test your own interpretation. M: It would be like trying out my ideas on other people. W: Yes, you could say so. M: That might help me with my papers—lay out my ideas and see what other people think. W: Sure, discussing ideas with your classmates is always stimulating. I strongly recommend it. However, for help with your papers, my advice is to find a tutor or go to the Writing Center. M: Are there tutors at the Writing Center? W: There are teaching aides that will read your paper and suggest ways to improve it. M: Sounds good. If it helps raise my grade, I’d be very happy. Thanks, Professor. I appreciate your advice. W: You’re very welcome. I’m glad you came to see me. 1. Why does the student go to see his professor? 2. How does the student probably feel when he says this: “I already study hard for this class.

How are you? W: Very busy—too busy, actually. M: How’s basketball going? W: Great—the team is doing very well this year. Unfortunately, though, I may have to quit the team. M: Quit? Why? W: I love playing, but basketball takes too much of my time, and I have less time for the debate club, my other activity. I have to make a decision soon, and it’s very hard. I have to give up one or the other. M: Don’t give up basketball! You’re one of the best players, and it would hurt the team. W: If I quit basketball, I’d have more time for debate, but I’d disappoint the team. Besides, I’d get less exercise. On the other hand, quitting the debate club might hurt my chance at getting a debate scholarship, which I’m almost certain to get, according to the debate coach. M: It’s a tough choice, but maybe the scholarship is more important. You can always play basketball next year, or just play a little for exercise. Besides, don’t you want to go to law school? Debate is good preparation for that. W: I do want to go to law school, but I also love basketball. My problem is, which is less essential now? The students discuss possible solutions to the woman’s problem. Describe the problem. Then state what you think the woman should do, and explain why.
