Conversation Two
M: [22]Can you tell me something about the university shuttle bus system? This is such a large campus, and I have classes all over campus. I need to take the shuttle bus from one class to another, or I'll never make it on time.
W: What do you need to know? I think it's a really great system.
M: First of all, where does it go?
W: [23]The university shuttle bus system goes all over campus. It doesn't leave the campus; if you want to travel off-campus, you'll need to take the city bus system. But the university shuttle bus system will get you from one class to the next very efficiently.
M: And how much does it cost?
W: [24]It's free, can you believe it? So you don't have to pay a cent to get all around the university campus.
M: That's really great. And how do I catch the shuttle bus?
W: [25]Just look for one of the bright yellow shuttle bus signs, and go stand next to it. You can see the yellow shuttle bus signs all over campus. A shuttle bus will come along approximately every five minutes, so you shouldn't have to wait long.
M: That all sounds good. Thanks for your help.
W: No problem.

Questions 22 to 25 are based on the conversation you have just heard.
22. What are the man and woman discussing?
正确答案：D
解析：选项全是名词短语，问对话主题的几率颇大。对话开头的第一句话就点出了答案所在，即D。如果实在没有听懂第一句话，后面还有机会听出答案，因为全文讲的都是the university bus system。
23. What area does the university shuttle bus cover?
正确答案：A
解析：选项都是地点和范围，而且选项之间有包孕关系。在范围上，C包含A、B和D，所以可以初步排除C。听到第一句话讲的是the university bus system，就可以排除D（人家说了是校内巴士，怎么会包括校外地区呢）。所以关键是要听清巴士线路是否通达全校。标志词组“First of all”后面紧跟着一个问句，注意听答案。A正确。
24. How much does the shuttle bus cost?
正确答案：A
解析：从选项可以看出，问的是“多少钱”，马上就知道一定是问巴士车票多少钱。根据关键表达free（免费的）和don't have to pay a cent，可知答案为A。
25. What color are the shuttle bus signs?
正确答案：C
解析：看到选项都是颜色，就要格外留神听对话中出现颜色的地方。对话两次提到yellow这个词，且未提及其他颜色，故不难得出答案C。
