W: I've just decided to order some books from this catalogue. I wonder how I should pay for them.
M: You can save two dollars by paying in cash or by check instead of using a credit card.
答案解析：
正確答案為A。根據You can save two dollars by paying in cash or by check instead of using a credit card.如果你不用信用卡，用現金支付或用支票的話可以省兩美元。可知，男子建議女子用現金或支票支付，不建議用信用卡，因此C項排除，B項是不用支票，與對話內容相悖，排除。因此A項正確。

M: I have a high fever and I think I'm going to die.
W: Well, let me examine you first. How long have you been like this?
M: A week. Is it serious?
W: Nothing serious. Take some medicine and you will get well soon.
答案解析：
正確答案為C。根據I have a high fever and I think I'm going to die.我發高燒，我覺得我快死了。可知，男子現在感覺很不舒服，因此C項正確。A項，他很好，與對話內容不符，對話中男子發高燒，身體狀況并不好，A項排除。B，他快死了，對話中男子發高燒，只是一種表達自己很不舒服的夸張說法，并不是真實情況，排除。
