录音原文：
11.
W: I suppose you've bought some gifts for your family.
M: Well, I've bought a shirt for my father and two books for my sister, but I haven't decided what to buy for my mother, probably some jewels.
解析：

D 此题关键是信息对应，在听录音的同时做记录（shirt-father,books-sister, probably jewels for mother）,然后仔细听问题“books买给谁”。

12.
W: Look! It says they want a junior sales manager, and it seems like it's a big company. That'll be good, for you might have to travel a lot.
M: Do they say anything about experience?

A 关键是要抓住核心词：销售经理(sales manager)，大公司(big company),经常出差(travel a lot)和工作经验(experience)。招聘职位是销售经理，而不是B（总经理的职位），也不是D（毫无经验的推销员），对话中的travel是指出差，而非旅行，故与C（旅行社）无关。本题符合短对话的常用解题原则之一：听到什么不选什么，因为很多干扰项都是以读者像是作为出发点的。
