Question 11 is based on the conversation you have just heard.

听力原文

M: Hi, Christie’s Gym Center. How can I help you?

W: Hi. I’m calling to ask about the newly scheduled gym classes. I’m just wondering if I can get a discount on them.

M: Are you already a member?

W: (8) [Yes, I signed up two months ago,] but I haven’t been to any of the group classes yet.

M: Can I take your name please?

W: Yes, my name’s Carol Friedman.

M: Carol Friedman. That’s right, and you signed up two months ago. (9) [Currently we are offering existing members discounts off two of our brand-new classes]—hot yoga and advanced spinning. But the discount doesn’t apply to any of our regular classes, I’m afraid.

W: I’m only interested in the new classes. So how much of a discount is there on these two new classes?

M: The same discount of 20% is being offered to everyone at the door on a first-come, first-served basis for the first month. (10) [It’s a shame you missed out on the general discount.] 

W: I see.

M: But you can get 25% off if you sign up in advance. Which of the two classes are you thinking about?

W: Well, I guess I am only really interested in hot yoga. Can you sign me up for the ten-week course on Thursday evenings?

M: Sure. Would you prefer to pay in advance？

W: No. (11) [I don’t like giving my card details over the phone, anyway.] 

M: OK, then. As you are already a member, the fee for the class will just be added to your monthly bill.

W: That’s perfect. Thanks for your help.

M: See you Thursday.

11. Why is the woman unwilling to pay in advance?（为什么女士不愿意提前付款？）

解析：D。在录音结尾，男士问女士是否愿意提前付款，女士予以拒绝，并解释说自己不喜欢在电话里提供银行卡的详细信息。D项与此内容相符，其中的reveal是对录音中giving的同义替换，card details over the phone原词复现，故D项为正确答案。

错项排除：A项利用录音结尾男士说的added to your monthly bill设置干扰，但这并不是女士拒绝提前付款的原因，故排除。录音中未提到女士会随时取消注册，或是认为在上课前付款不够明智，B项里的cancel和C项的wise在录音中无依据，故均可排除。
