Conversation Two
M: Well, Claudia, how is your first day on campus working out?
W: Actually, I’m overwhelmed. This campus is too large. I’m not really sure how to get around. How about you?
M: Yeah, I’m having the same problem. That’s why we should leave a bit early to get to our biology class on time.
W1: That sounds like a good plan to me! It’s 9:30 right now. I think our class starts at 10:00 a.m.
M: Actually it starts at 10:15 a.m., which leaves us 45 minutes to find it. The schedule says the class is in the Darwin Building, but I can’t seem to find it on the map.
W1: Since we both don’t know where we are going, why don’t we ask that woman sitting on the bench, she seems to know her way around here.
M: All right, it can’t hurt to ask.
M: Excuse me Miss, could you tell us how to get to the Darwin Building?
W2: The Darwin Building? Oh yes, I remember… Do you see that building to our right there? That’s the East Dormitory. Next to it is the Science Library. What you should do is follow the path between those two buildings until you reach the other side. Then take the left-hand path and follow it to the end. It leads straight to the Darwin Building. Got it?
W1: I think so, after we pass between the Dorm and the Library, we follow the path to the left until the end of the road, then we should be there, right?
W2: Yes, that’s perfect.
M: Thank you very much, indeed.
W2: You are welcome.

Section B
Directions: In this section, you will hear 3 short passages. At the end of each passage, you will hear some questions. Both the passage and the questions will be spoken only once. After you hear a question, you must choose the best answer from the four choices marked A), B), C) and D).
Then mark the corresponding letter on Answer Sheet 2 with a single line through the center.
Passage One
The world is not only hungry; it is also thirsty for water. This may seem strange to you, since nearly 75% of the earth’s surface is covered with water. But about 97% of this huge amount is sea-water, or salt water. Man can only drink and use the other 3% — the fresh water that comes from rivers, lakes, underground, and other sources. And we cannot even use all of that, because some of it is in the form of icebergs and glaciers. Even worse, some of it has been polluted.
Our need for water is increasing rapidly. Only if we take steps to deal with this problem now can we avoid a severe worldwide water shortage later on. One useful step we should take is to develop ways of reusing it.
Today, in most large cities water is used only once. But it is possible to pipe water that has been used to a purifying plant. There it can be filtered and treated with chemicals so that it can be used again just as if it were fresh from a spring.
But even if every large city purified and reused its water, we still would not have enough. Where could we turn next? To the oceans! All we’d have to do to make use of the vast amount of sea-water is —— remove the salt. This salt-removing process is already in use in many parts of the world. So if we take all these steps, we’ll be in no danger of drying up!
Questions 26 to 28 are based on the passage you have just heard.
26. What percentage of the earth’s water can man actually use?
27. How can we avoid a worldwide water shortage in the future?
28. How can sea-water be turned into fresh water?
