【正确答案】 A

【答案解析】[听力原文] W: Hi, John. How are things going? M: Oh, hi. Fine. How about you? W: You can probably tell just by looking at me. I'm really busy. Well, what are you reading? M: A very interesting article. My biology professor assigned it. I thought I would just look it through, but I got really involved in it. It's about endangered species. W: That sounds pretty interesting. I'm getting frustrated with the two research papers I'm struggling with. M: Oh? W: Besides, they are both due on the same day. It's unbelievable. M: That's tough. W' I'll get through it. So what's this you are reading? M: Well, it's basically about the choices conservationists are facing with. You know, these days funding is so hard to come by. W: Wait a minute. Is the focus on biology or economics? M: Both. Conservationists don't have enough funding to save every endangered species in the world, so they have to decide, based on what would be lost if a species became extinct. W: Can you give me an example of what you mean? M: Take for instance, two animals, the spotted owl and the tailed toad. The article says the toad is unique. It has no relatives. But there are a lot of varieties of owls. W: So, if that toad became extinct, we'd lose an important link in the chain of evolution, right? M: Exactly. But that isn't so for the owl. So for conservationist, it might be a clear choice of which animal to save. What is the man doing? 细节题。女士直接问男士“What are you reading?”，可知男士是在阅读。男士答道，他在读一篇非常有意思的文章，是关于濒危物种的。而后，两人就文章的内容展开了讨论。

【答案解析】[听力原文] Why can't the conservationists save every endangered species? 细节题。男士说，如今保护动物的事业很难申请到基金，所以环境保护者没有足够的资金来拯救所有的物种，他们不得不从物种中作出选择。

单选题

A、 The spotted owl.
B、 The tailed toad.
C、 Both of them.
D、 Neither of them.

【正确答案】 B

【答案解析】[听力原文] As for these two kinds of endangered species spotted owl and tailed toad, which one will be chosen to be saved according to the conversation? 推理题。对话末尾以斑点猫头鹰和长尾蟾蜍为例进行了说明，长尾蟾蜍是独一无二的物种，没有近亲，但猫头鹰却有很多种，女士进而说明，如果长尾蟾蜍灭绝了，我们就会失去进化链中的重要一环，男士对此进行了肯定，并说而斑点猫头鹰就不会这样。再由前文说到由于资金不足，环保主义者只能从濒临灭绝的物种中选择性地进行保护。由此可推知会选择长尾蟾蜍。故选B。
