Conversation One
M: Are you going to the demonstration to help stop the spread of nuclear weapons tomorrow, Cleo?
W: No, Simon. I hate demonstrations. I have heard the police will be standing by with tear gas.
M: Yes, but North Korea boasts it has nuclear arms.
W: One hundred ninety countries have signed the Nuclear Non-Proliferation Treaty but the issues are just too complex. There are two sides to every story. I don't understand it and I have no intention of going to a demonstration. [19]Demonstrations don't seem to accomplish anything anyway.
M: [19]Several demonstrations have changed politician's minds throughout history. As a responsible citizen I think it is important to stand up for what you believe in.
W: Leave it to someone else. As I said, if you listen to both sides of a story, both sides have some good points. [20]Why should I demonstrate and risk getting hurt for something that I am not even sure is right?
M: You are not likely to get hurt. This will be a peaceful demonstration. I have spoken to the organizer for the university group. He insists that this will be peaceful. He advocates if you want world peace, peace begins at home-and that means right here in this city.
W: [20]/[21]You go if you want, Simon, but I plan to study for my physics exam.
M: It would only take two hours of your day. The bus leaves the campus at 11:30 and leaves downtown to return to campus at 12:45. You could eat your lunch on the bus.
W: [20]/[21]I am not going, Simon. [21]Why don't you ask the students in your political science class this afternoon if they want to go?
M: They are all going.
W: Okay, Simon. I need to meet my sister for coffee now.
M: Bye then. See you in physics class tomorrow.

Questions 19 to 21 are based on the conversation you just heard.
19. What do the two speakers mainly disagree upon?
正確答案：C
解析：這個對話圍繞是否去參加demonstration展開，故C正確。nuclear weapon只是demonstration的導火索，A不是二人爭論焦點。
20. How does the woman react to the man's persuasion?
正確答案：A
解析：女士一再表示自己不會像其他人一樣去參加自己不知道對錯的事情，故A為答案。
21. What is the man's purpose in talking with the woman?
正確答案：D
解析：不定式表示目的，問題肯定是問男士跟女士談話的目的。圍繞主題以及女士的反問“你為什么不讓……去呢？”很容易做對此題。
