Question 15 is based on the conversation you have just heard.

听力原文

M: Okay, Miss Bright. I’ve finished calculating. I estimate you have between 210 and 240 square meters of walls and ceiling.

W: (12) [So how much would the paint job cost?]

M: That would depend on the quality of paint you choose. We carry two brands—one costs 60 cents every square meter, and the other 90 cents. The second is guaranteed to look great for about 10 years, whereas the cheaper one will start to dull after around 6 or 7 years.

W: In that case, we would prefer the more expensive option.

M: All right, then. So including labor costs, taxes, and everything, this job would come to $3,000.

W: (13) [Emm, to be perfectly honest, that’s more than I expected.]

M: Please bear in mind that the price includes moving all the furniture, and the whole task would take 2 days.

W: Really? Why?

M: Well, we can’t paint the walls without clearing all the furniture first. So every time we paint a room, we first have to move the furniture to another room. So that takes more time. Plus, it requires two people, which works out more expensive.

W: I see. But does that mean I could not live here in my own house during those 2 days?

M: That is correct.

W: Oh well, that changes everything I’m afraid. (14) [I would have to stay with a friend or check into a hotel.] I hadn’t considered any of that. (15) [I’m starting to realize that painting my house is far more troublesome than I had anticipated.] 

M: This is usually the case. Most of our clients go through the same realization.

W: I see.

M: You have my number. Please feel free to call me for any further questions.

W: Thank you. 

15. What has the woman come to realize at the end of the conversation?

解析：B。在录音结尾部分女士说到，她现在知道了，粉刷房子比原先预料的要麻烦得多，B项中的involves more trouble是对录音中far more troublesome的同义替换，故B项为正确答案。

错项排除：A项利用录音中的friend进行干扰，但录音中是说可能需要住在朋友家，并不是说请朋友帮忙粉刷，故A项排除。录音中女士提到如果不能在房子里住，那一切就需要改变一下，但并没有说她应该早点重新粉刷房子，C项过度推断，故排除。D项利用录音中的moving all the furniture进行干扰，但并没有说搬动家具比粉刷还要难，故D项排除。
