【答案解析】[听力原文]11-14
W: Hi, Jack. It's good to see you again. Are you ready to get down to business again after spring break?
M: Not really, but I guess I don't really have too much choice, do I? And it's going to be particularly hard to get back to work since I just had the most fantastic vacation ever.
W: Really? What did you do?
M: I went boating on the Klamath River?
W: Is that so interesting?
M: Yeah. The boat is quite long and narrow, used to be used by the Indians. Controlling it is not easy.
W: Weren't you scared?
M: At first, I was. But after I learned some techniques for controlling it, it wasn't so bad. We didn't start out on the river. We had three whole days of instruction in a shallow pool first. Then, when we finally got out on the river, I felt ready for it.
W: Did you spend the nights camping outside on the ground? That alone would make the trip unappealing to me.
M: Oh, no. The accommodations were fantastic. Each person on the trip had a private cabin, and the facilities are good. The food is also good.
W: Now, that part of the trip does sound good to me. But I don't think I'd like the part that involves riding through rough water in a small boat.
M: Oh, you should try it; I know you'd like it. I'm going to do it again myself, as soon as I can afford to spend the time and the money.

细节题。从对话开始部分的寒暄中，可以知道对话发生在“after spring break”，因此可以推断出，这是刚刚放完春节假期。所以答案应当选择D项。

单选题 What are the man and woman discussing?

A、 A trip to visit the Indians.
B、 A trip the woman is planning to take.
C、 A trip the man has already taken.
D、 A camping trip the man and woman took.

【正确答案】 C

【答案解析】综合理解题。从整个对话内容，我们可以知道他们谈论的内容是关于这个男生在刚刚过去的假期中的生活。所以答案C项符合要求。

单选题 How much instruction did the man have before going out on the river?

A、 Three hours.
B、 Three complete days.
C、 Three classes.
D、 Three weeks.

【正确答案】 B

【答案解析】男生说“We had three whole days of instruction a shallow pool first．Then，when we finally got out on the river，I felt ready for it”从而可以知道，在最终到河里划船之前，必须要在一个浅水池塘里进行预备联系，因为他们要操纵一种并不容易操作的印第安人使用的小船。从而答案应当选择B项。

单选题 Which of the following is NOT part of the trip?

A、 Sleeping outside on the ground.
B、 Spending time in a private cabin.
C、 Boating on the river.
D、 Enjoying excellent food.

【正确答案】 A

【答案解析】从整个讲话内容来看，B、C、D项都有提到，唯有A项没有提到，而且对话中谈到住宿条件是非常好的，每个人都有一个小屋(The accommodations were fantastic．Each person on the trip had a private cabin)，所以只有A项与对话内容不符。
