W: Mr. Watson, I wonder whether it's possible for me to take a vacation early next month.
M: Did you fill out a request form?
Q: What is the probable relationship between the two speakers?
正確答案：C
解析：關鍵是要聽到女士說要“休假”，而男士要求她“填寫申請表”，可以斷定是上下級關系，故答案為C。

M: Do you want to go to the lecture this weekend? I hear that the guy who is going to deliver the lecture spent a year living in the rainforest.
W: Great! I am doing a report on the rainforest. Maybe I can get some new information to add to it.
Q: What does the woman mean?
正確答案：B
解析：本題關鍵在于聽懂女士所說的“沒準我可以獲得一些新信息來加到我的報告中去。”也就是說她認為這個講座富含信息，故答案為B。選項A、D是利用原文中個別單詞制造的干擾項；C錯在her lecture，講座是the guy而不是她做的。
