【正确答案】 C
【答案解析】[听力原文] M: Thanks for coming over, Tracy. I'd like to talk to you about a research project I thought you might be interested in. A friend of mine is working in Iowa National Park this summer. W: A national park! I've always wanted to spend some time out in Iowa. M: You'd better hear what the project is about first. My friend is working with the red fox population. The foxes have been increasing in size lately, which is good in theory. W: Yeah, but I thought they were in danger of dying out. M: Because of the winter tourists, paths are created in the snow. More red foxes are surviving the harsh winters because the paths make it easier for the foxes to move around and find food. But it turns out that some of them are infected with bacteria. W: Oh yeah, I heard about that. It's been around for a while. M: Yes. And because the red fox population is increasing, they've been moving more than usual and need more food, they began to hunt in the farm which borders the national park. As a result, the bacteria have spread to the neighboring farms. W: That's bad news. Isn't that the disease that causes animal abortion? M: Yes, and it has caused a lot of controversy. Some of the farmers even want to destroy the red foxes. W: That's awful. Have they made much progress with the research? M: So far, they have been collecting tissue samples from dead foxes to see if the bacteria are present. W: I'd really be interested in working on this. You know I've been researching diseased animal population. M: That's why I thought of you. What is the man talking about with the woman? 对话开头男士就直接提到I'd like to talk to you about a research project I thought you might be interested in.,由此可知,他们在讨论一个女士可能会感兴趣的研究项目,故答案为C。 开头部分往往点明对话的主要内容,听音时要特别留意。
