Question 5 is based on the conversation you have just heard.

听力原文：

W: I have many business English students. When I teach the classroom, we often end up talking about things like success and what leads to success. And it’s interesting that many of them mention the element of luck.

M: Right.

W: Luck is important to success. But since you’ve seen that fantastic video on the TED Talks website by Richard St. John, he doesn’t mention luck at all.

M: Well, I’m a firm believer that people can make their own luck. I mean what people regard as luck, you can actually create, to a degree.

W: Sure. I think a lot of what people consider luck is attributed to how you respond to the opportunities that come your way.

M: Yes. Very good point.

W: Seizing the opportunities. But was there any point in the video that you thought was particularly interesting?

M: Yes. Actually there was. Something very impressive to me is many people think that luck is important and that natural talent is something you must have in order to be successful. And in the video we saw, the point about getting good at something is not about having some natural talent. It’s all about practice, practice, practice.

W: Definitely yeah. Natural talent helps in some way but at the end of the day you really do need to work hard and get really really good at what you do.

M: Sure.

W: I thought one interesting thing in the video was the idea of passion being so important, and there’re people who really love what they do. Of course, you’re going to want to work harder and put the time and effort into it. And the funny thing is that if you love what you do and are really passionate about it and work really hard, then money kind of comes automatically.

5. What are the speakers mainly talking about?

解析：B。本题目为主旨题。问题为：讲话人主要说了什么内容？主旨题考对全文讨论内容的归纳能力，文章提到了luck、talent、practice、passion和success，讲述的是成功的四个因素。选项中分别出现了luck、talent、practice和success，但是文章主要讲述的是成功的影响因素，而不是重点讨论某个具体因素。所以与选项B) What determines success（成功的决定因素），与对话主旨相一致。其他干扰选项属于细节干扰。
