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?
正确答案：A
解析：男士的话是虚拟语气，表示不可能实现的愿望。既然男士对盐水会过敏，自然就会避免接触海水。故答案为A。根据选项可预测问题有关男士的做法，且对话内容与“去海边游玩”有关。虚拟语气反着选答案。

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?
正确答案：B
解析：女士说：“我很幸运，它只占这门课期末成绩的一小部分。”说明她的quiz成绩不好。所以B正确。根据选项可预测对话是关于女士的quiz成绩。本题是很典型的“有问不答”，或者表面上看来“答非所问”的题目，听懂话外之音即可准确作答。
