Now you'll hear the two long conversations.
Conversation One
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. [19]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 blush like crazy if he calls on me. Doesn't that ever happen to you?
M: No, not really. [20]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 it in psychology class. Blushing, even though it's involuntary, is more or less a learned behavior.
W: What do you mean?
M: [21]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 have a friend at 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.

Questions 19 to 21 are based on the conversation you have just heard.
19. What is the woman's problem?
正確答案：A
解析：四個選項都是描述“她”遇到的問題，聽錄音時要格外留意女士的話。女士說：“我只要是在人群面前說話就會感覺很尷尬、緊張。”故答案應為A。由對話中多次提到的get/turn red, blush也可猜出正確答案。
20. What does the man advise the woman to do?
正確答案：B
解析：男士說：“或許你應該努力忘記人群。看看房間里面的其他東西，比如出口指示牌。”故答案應選擇B。
21. What does the man say about children?
正確答案：D
解析：選項中的They與women, adults進行了比較，故猜測They可能是指小（男）孩，聽音時要留意談到children或boys的句子。男士說：“小孩子們基本不會臉紅。”故D正確。
