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：
正确答案为A。根据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，用现金支付或用支票的话可以省两美元。可知，男子建议女子用现金或支票支付，不建议用信用卡，因此C项排除，B项是不用支票，与对话内容相悖，排除。因此A项正确。

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：
正确答案为C。根据I have a high fever and I think I'm going to die.我发高烧，我觉得我快死了。可知，男子现在感觉很不舒服，因此C项正确。A项，他很好，与对话内容不符，对话中男子发高烧，身体状况并不好，A项排除。B，他快死了，对话中男子发高烧，只是一种表达自己很不舒服的夸张说法，并不是真实情况，排除。
