M: What a stupid guy! A real troublemaker!
W: Yeah! He can't do anything right. He knows nothing about this business. I can't figure out how he got in this company.
Q: Who are they probably talking about?
正确答案：B
解析：男士说：“真是个蠢家伙！真是个麻烦制造者！”女士回答：“是的……关于这业务，他一无所知。我不知道他是怎么进到这公司的。”可见他们谈论的是公司里的同事，故B正确。

M: Have you finished reading the book you bought last month?
W: Oh, I didn't read it straight through the way you'd read a novel. I just covered a few chapters that interested me most.
Q: How did the woman read the book?
正确答案：A
解析：预读选项可知，题目询问女士阅读的方式。本题关键在于听懂女士说“我没从头读到尾”以及她后面的补充说明“我只读了最令我感兴趣的几章”，二者结合即A“她有选择地读”。
