W: I need to find a baby sitter to take care of my son. Do you know Mrs. Peterson? I heard she is usually available at weekdays.
M: Well, I know that baby sitter. But the best I can say for her is she has a great fantasy to the TV in her living room.
Q: What does the man imply about Mrs. Peterson?
正確答案：B
解析：女士問男士是否認識保姆Mrs. Peterson，男士說她非常喜歡看電視，言下之意不會向女士推薦這個保姆。故答案是B。從選項可以預測，問題與男士的態度和做法有關。“But”后內容是聽音關鍵。

W: May I try this dress? Hmm, size 10, please.
M: Sure! Ma'am, we only have two of them left. They're on sale today, and the deal will be made on a first-come, first-served basis.
Q: What does the man mean?
正確答案：B
解析：女士想要試穿衣服，男士說這件衣服只剩下兩件了，今天特價，先到先得。所以答案為B。根據選項可以預測，男士是賣方，女士是買方，問題與男士的銷售方式有關。商鋪經常會掛出“on sale”的牌子，所以這個表達應該不會陌生。
