【正确答案】 D

【答案解析】[听力原文] 11-14
W: Hi, John.
M: Oh! Hi, Laura. What are you doing here?
W: Uh, I'm usually here on weekends. It's my uncle's shop. So you are looking for a bike?
M: Yeah. Now that the weather is warming up, I thought I should get some exercise instead of taking the bus all the time.
W: Well, that's a good idea and you come to the right place. Do you know what you like?
M: Well, I don't want a racer or a touring bike or anything like that. Mostly I'll just be using it to get me back and forth from work.
W: How far is that?
M: About four miles.
W: Are there a lot of hills on the way?
M: Some, I guess. But maybe I should tell you at first that I only got 150 dollars. Can I get anything decent for that?
W: Well, you are not going to get anything on the top of the line. But we do have a few trade-ins in the back that are in good condition.
M: That sounds good.
W: And you are right. For the kind of ride you are going to be doing, the most important thing is comfort. You want to make sure it's the right height for you? Follow me and I'll show you what we've got.

本题带有推断性质。在第一个话轮中，男士询问女士在那儿干什么(What are you doing here)，接下来的一个话轮中女士没有明确回答，而是交代了两个信息：一是I'm usually here on weekends，二是It's my uncle's shop。而从后续对话不难看出，女士一直是作为店员在为男士选自行车。综合这些方面，就可知答案是[D]。其余各项都属于随意发挥或者是原文中没有的内容。

【正确答案】 B

【答案解析】本题属于细节题。选项[B]就是对男士在第二个话轮中I thought I should get some exercise和第三个话轮中I'll just be using it to get me back and forth from work两处的综合和归纳，因此是正确答案。其余各项都与此意不符。

【正确答案】 A

【答案解析】本题关键是理解女士在第六个话轮中所说trade-in一词。它指“折价的旧物品”，相当于[A]项中的used bicycle。由于女士的这句话出现在男士说自己只有150美元之后，因此根据常识不难推断出女士是针对男士的这一情况给出建议。其余三项都属于抓住对话中的个别词句进行的元据发挥。

【正确答案】 A

【答案解析】本题属于带有推断性质的细节题。在最后一个话轮中，女士明确指出：the most important thing is comfort，但选项中并没有重现comfort一词，因此它肯定有具体所指。细听后面的话，发现女士要求男士make sure it's the right height for you，根据逻辑和常识即可判断出这正是女士所说的comfort的具体内容，因此本题应选[A]项。其余三项所涉及的都是对话中没有出现的信息，均可排除。
