Question 3 is based on the conversation you have just heard.

Conversation One

听力原文

M: You are a professor of physics at the University of Oxford. You’re a senior adviser at the European Organization for Nuclear Research. You also seem to tour the globe tirelessly giving talks. And, in addition, you have your own weekly TV show on science. Where do you get the energy?

W: (1) [Oh, well, I just love what I do. I’m extremely fortunate to have this life, doing what I love doing.]

M: Professor, what exactly is your goal? Why do you do all of this?

W: Well, as you said, (2) [I do have different things going on, but these, I think, can be divided into two groups: the education of science and the further understanding of science.]

M: Don’t these two things get in the way of each other? What I mean is, doesn’t giving lectures take time away from the lab?

W: Not really, no. I love teaching, and I don’t mind spending more time doing that now than in the past. (3) [Also, what I will say is that teaching a subject helps me comprehend it better myself.] I find that it furthers my own knowledge when I have to explain something clearly, when I have to aid others in understanding it, and when I have to answer questions about it. Teaching at a high level can be very stimulating for anyone, no matter how much expertise they may already have in the field they are instructing.

M: Are there any scientific breakthroughs that you see on the near horizon? A significant discovery or invention we can expect soon?

W: The world is always conducting science and there are constantly new things being discovered. (4) [In fact, right now we have too much data sitting in computers.] For example, we have thousands of photos of planet Mars taken by telescopes that nobody has ever seen. (4) [We have them, yet nobody has had time to look at them with their own eyes, let alone analyze them.]

3. What does the woman say about the benefit teaching brings to her?

解析：A。四个选项中均出现了形容词比较级，听音时需要注意录音中出现的比较级。题目问的是教学所带来的好处（benefit）。女士在录音中提到“教授一门学科有助于我更好地（better）理解它。”A项与此内容相符，其中的subject为原词复现，better understanding对应录音中的comprehend it better，故A项为正确答案。

错项排除：C项利用录音中的furthers my own knowledge设置干扰，但录音中女士只说到教学会让她加深对这一学科的认知，并没有说会有一个更广泛的了解，broader一词在录音中没有依据，故排除C项。B项和D项在录音中均未提及，故排除。
