W: I read an article about the auction websites. They seem quite good!
M: Well, these sites are set up to make money fast, and you never know what you're paying for. I won't take the chance. Why not go buy something at a discount from a real department store?
Q: What does the man think of auction websites?
正確答案：B
解析：女士說閱讀了一篇關于拍賣網的文章，覺得拍賣網很不錯。男士說拍賣網都是賺“快”錢的，你永遠不知道你到底買了什么東西，自己不會去冒險，并建議女士去百貨商店買降價貨品。所以答案為B。前三個選項都帶形容詞結構，可猜測題目與某物的性質有關。即使沒有聽清楚男士長篇大論的意見，從最后一句“何不在百貨商店降價的時候買東西”也可以推測出，男士對拍賣網沒有持肯定的評價。

W: John really gave me a big surprise yesterday.
M: I bet. He appeared at the wedding catching everybody's eye, because he was wearing jeans and everyone else was dressed so formally. Didn't he read the instruction on the invitation letter about the dressing code?
Q: What can we learn from the conversation?
正確答案：D
解析：根據對話，大家都穿著正式參加婚禮，但John卻穿著牛仔褲，顯得格外突兀。故答案是D。選項告訴我們，問題與John在婚宴上的穿著有關。既然有對話雙方這樣的討論存在，就說明討論的對象與眾不同。強干擾項A利用女士的話做文章來進行夸大，但是從原文中并不能推導出A這樣的結論。
