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.
听力原文： (26)What is love？ And how does it come？ Charles Zastrow, a famous American professor, offers an interesting answer, particularly to the second question. He argues that there are many kinds of love(27) and that particularly in one kind, which he calls "romantic love", we are strongly influenced not so much by what we actually feel but by what we tell ourselves about the way we feel. He calls this "self-talk". For example, say a woman is strongly attracted to a man. She tells herself things like "He is all I have ever wanted in a man!" But when she discovers that he is just an ordinary human being with both strong and weak points, she is bitterly disappointed.
Zastrow says that particularly in romantic love, our self-talk comes from "intense, unsatisfied desires and frustrations", (28)and that this kind of love often requires distance. "The more forbidden the love, the stronger it becomes." He points out that this kind of love begins to fade and die as soon as a normal relationship begins.
He contrasts romantic love with what he calls "rational love". This is based on such things as the ability to communicate with each other openly, so that you can deal with the problems as soon as they appear, and a clear knowledge of your own goals in life. (29)This kind of love leads to a lasting, satisfying relationship, but it is much more difficult to achieve, and is not as frequent as romantic love.

Section B
Directions: There are 2 passages in this section. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A, B, C and D. You should decide on the best choice.
The very high temperatures attained in a nuclear explosion result in the formation of an extremely hot intense mass of gas called a fireball. For a l0-kiloton (千吨，核弹当量单位) explosion in the air, the fireball will attain a maximum diameter of about 300m; for a l0-megaton (兆吨，核弹当量单位) weapon the fireball may be 4.8 km across. A flash of heat radiation is emitted from the fireball and spreads out over a large area, but with steadily decreasing intensity. The amount of heat energy received a certain distance from the nuclear explosion depends on the power of the weapon and the state of the atmosphere. If the visibility is poor or the explosion takes place above clouds, the effectiveness of the heat flash is decreased. The heat radiation falling on exposed skin can cause what called flash burns. A 10-kiloton explosion in the air can produce moderate (second-degree) flash burns, which require some medical attention, as far as 2.4 km from ground zero; for a 10-megaton bomb, the corresponding distance would be more than 32 km. milder burns of bare skin would be experienced even farther out. Most ordinary clothing provides protection from the heat radiation, as does almost any opaque (不透明的) object. Flash burns occur only when the bare skin is directly exposed, or if the clothing is too thin to absorb the heat radiation.
The heat radiation can start fires in dry, flammable materials, for example, paper and some fabrics, and such fires may spread if conditions are suitable. The evidence from the A-bomb explosions over Japan indicates that many fires, especially in the area near ground zero, originated from secondary causes, such as electrical short circuits, broken gas lines, and upset furnaces and boilers in industrial plants. The blast damage produced wreckage that helped to maintain the fires and denied access to fire-fighting equipment. Thus, much of the fire damage in Japan was a secondary effect to the blast wave.
Under some conditions, such as existed at Hiroshima but not at Nagasaki, many individual fires can combine to produce a fire storm similar to those that accompany some large forest fires. The heat of the fire causes a strong updraft (向上排气), which produces strong winds drawn in toward the center of the burning area. These winds fan the flame and convert the area into a disaster in which everything flammable is destroyed.
It can be inferred that amount of radiation______.
听力原文：M: Hi, Sarah. What's up？
W: Oh, hi, I just got out of a history class. I had to give a presentation.
M: How did it go？
W: Terrible. I'm sure I made a fool of myself.
M: Why？ Weren't you prepared？
W: No, it was not that. (23) I just get so embarrassed and nervous whenever I have to speak in front of a group of people. I stand up and my face gets red and then I get even more nervous because I know everyone can see me blushing.
M: It's not so bad to blush.
W: But it happens all the time. If the professor asks a question and I know the answer. I will blush like crazy if he calls on me. Doesn't that ever happen to you？
M: No, not really. (24)Maybe you should just try to forget about the people. Look at something else in the room, like the exit sign.
W: I guess I could try that. But I doubt it'll help.
M: You know we talked about this in psychology class. (25)Blushing, even though it's involuntary, is more or less a learned behavior.
W: What do you mean？
M: (25)Oh, children hardly ever blush at all. And among adults, supposedly, women blush more than men.
W: I wonder why？
M: I don't know, but I had a friend in high school, Brian Smith. It was really easy to make him blush. He turned red whenever a waitress would ask him for his order.
W: I'm not that bad. Well, I've got to get going for my next class. I'll talk to you later.
