Question 9 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.

9. What do we learn about the man’s neighbor from the conversation?（通过对话，我们能了解到男士邻居的哪些信息？）

解析：D。此题可用到视听一致原则作答。录音中男士表示，他邻居的家要更大一些，他们是个大家庭，总共有六口人。因此D项符合题意，其中的has a large family在录音中复现，故为正确答案。

错项排除：录音中男士表示，他的邻居大约一年前在屋顶上安装了太阳能电池板，由此可知邻居已经安装了太阳能电池板，并非计划安装，故A项错误。录音中提到，邻居一家总共有六口人，但并没有说是几居室，而女士提到的四居室只是为举例说明安装电池板能节省多少钱，并不是邻居的情况，故B项错误。录音中男士提到，到目前为止，用太阳能电池板给热水器供电已经为他的邻居节省了500多美元，并非300美元，故排除C项。
