Question 8 is based on the conversation you have just heard.

听力原文

W: Rays Solar. Lisa speaking. How can I help?

M: Hi, my name is Winston. (8) [I wish to enquire about solar panel installations.]

W: Yes, what would you like to know?

M: Well, my neighbor installed panels on his roof about a year ago in order to power his hot water. He tells me it has saved him over $500 thus far. Does that sound about right to you?

W: Well, I’m not familiar with your neighbor or his particular setup, but that amount is definitely possible. I can tell you that the average four-bedroom house may typically have a roof with 50 square meters of surface area. Four panels on one side of that roof could save a family of four around $300 a year.

M: OK. That sounds about right then. My house is about the size you described, but my neighbor’s is bigger. I’m not sure how many panels he has up there, (9) [but he does have a large family of six.]

W: Are you interested in installing some solar panels on your roof, sir?

M: Yes, I’m considering it.

W: If you wish to come into our office, we could show you the different solutions we offer.

M: OK. I might do that. (10) [But just quickly, if you don’t mind, could you tell me approximately how much a typical installation costs, like, say, four panels?]

W: Prices do vary depending on different factors, but as a rough estimate, it’s around $2,000. But you know, (11) [a typical household will make back that initial investment in about five years.]

M: OK. I see. Thank you.

8. What is the man’s purpose for calling the woman? （男士给女士打电话的目的是什么？）

解析：C。此题可用到视听一致原则作答。录音开头男士明确表示想咨询一下太阳能电池板的安装情况，C项符合题意，enquire about solar panel installations在录音中复现，故为正确答案。

错项排除：录音中女士问男士是否有兴趣在屋顶上安装太阳能电池板，男士表示正在考虑，但这是女士向男士的提问，男士打电话的目的是了解太阳能电池板的信息，并非预约太阳能电池板安装服务，故排除A项。录音中并没有提到屋顶漏水或者太阳能电池板的故障问题，故排除B、D两项。
