Section B

听力原文：W: Stan, do you have a minute？

M: Oh, hi, Cathy. Sure. What's up？

W: Well, I've been meaning to talk to you about the situation in the office.

M: I'm not in there very often. It's so noisy that I can't work.

W : That's exactly what I'm getting at. We're supposed to be able to do our preparation and marking in that office, but have you noticed？ Jack constantly has students coming in to get help with his course. A lot of people are going in and out.

M: Has anybody spoken to him about it？

W: No, not yet, but someone's going to have to.

M: We can't really ask him to stop having students come in for help. Can we？

W: No, of course not. But I'm not able to do my work and neither are you. I imagine it's the same for the others in the office.

M: Hmmm, could we ask for a kind of meeting room？ When TAs have to talk with a student, they could go to the meeting room and not use the office. You know, there's a room down the hall, rather a small room that we could ask to use. It's only for storing supplies.

W: You mean that little storage room？ Oh, that would be too small.

M: Are you sure？ With the cabinets taken out, it might be bigger than it looks.

W: Come to think of it, you may be on to something. I'd like to have a look at that room. Can we go there now？

M: Sure, Let's go.

7. What problem at the office are Cathy and Stan discussing？

8.Why do Jack's students come to see him？

听力原文：W: Just a few reminders are necessary before you climb in. First, make sure you a

re properly grounded at the shore.

M: What do you mean by that？

W: I mean your canoe should be secure enough so that the moment you get in it, it doesn't float away on you.

M: But you wouldn't want it to be too grounded, would you？ Otherwise, it's a lot of work to push it from the shore.

W: Right, so try to have it parked securely enough that a simple shove from your paddle is all it takes to get you offshore.

M: What if the currents keep pushing you back to shore, after you've pushed off？

W: In that case, you may wish to "go with the flow" and let it glide you along the edges until you come across an area where you can push towards the center.

M: OK, got it. So, can we get in and get going？ I am dying to try out an Eskimo roll.

W: All right, but there are still some other tips I have to remind you of. For example, do you remember what you should never do when you're pushing off？

M: Yeah, I remember. Never lean forward. Always lean away from the shore. Let's just get out there so I can practice my Eskimo roll.

W: Come on Stan, as they say--walk before you run.

M: See you on the other side of the shore.

W: OK. Good luck!

M: Thank you again!

(1)

A．To make sure you are standing firmly enough at the shore.

B．To make sure you are properly equipped.

C．To make sure you are properly grounded at the shore.

D．To make sure you are properly grounded off the shore.
