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 that 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 notice？ 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: Hum, could we ask for a kind of meeting room？ When TAs have to talk with the students, they could go to the meeting room and not use the office. You know, there's a room down the hall; a rather 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 maybe on to something. I'd like to have a look at that room. Can we go there now？
M: Sure, let's go.

听力原文： President Bush told the soldiers their mission in Iraq is vital for peace and security, and that a free Iraq will be a blow to terrorists and their deadly aims.
"Part of their strategy is to use the killing of innocent people to get the American government to pull you out of there, before the mission is complete. I am going to assure you of this: that so long as I am the president, we are never going to back down. We are never going to give in. We will never accept anything less than total victory. It is important for you to know that. It is important for the enemy to know that, as well."

听力原文： There were several important discoveries in the early part of the century that helped geologists develop a more accurate picture of the earth's interior. The first key discovery had to do with seismic waves. Remember, they are the vibrations caused by earthquakes. Well, scientists found that they travel thousands of miles through the earth's interior. This finding enabled geologists to study the inner parts of the earth.
You see, these studies revealed that these vibrations were of two types: compression or P-waves and shear or S-waves. And researchers found that P-waves travel through both liquids and solids while S-waves travel only through solid matter. In 1906, a British geologist discovered that P-waves slowed down at a certain depth but kept traveling deeper. On the other hand, S-waves either disappeared or were reflected back. So he concluded that the depth marked the boundary between a solid mantle and the liquid core. Three years later, another boundary was discovered, that between the mantle and the earth's crust.
There are still a lot to be learned about the earth. For instance, geologists know that the core is hot. Evidence of this is the molten lava that flows out of volcanoes. But we are still not sure what the source of the heat is.
