W: So you are going to the beach next week?
M: I'd like to, if only I could get rid of this allergy towards salt water. You know how I love swimming.
Q: What will the man probably do?
正確答案：A
解析：男士的話是虛擬語氣，表示不可能實現的愿望。既然男士對鹽水會過敏，自然就會避免接觸海水。故答案為A。根據選項可預測問題有關男士的做法，且對話內容與“去海邊游玩”有關。虛擬語氣反著選答案。

M: How did you do on the math quiz?
W: Well, I am lucky that only accounts for a small portion of our final grade for the course.
Q: What can be inferred about the woman?
正確答案：B
解析：女士說：“我很幸運，它只占這門課期末成績的一小部分。”說明她的quiz成績不好。所以B正確。根據選項可預測對話是關于女士的quiz成績。本題是很典型的“有問不答”，或者表面上看來“答非所問”的題目，聽懂話外之音即可準確作答。
