Questions 4 to 6 are based on the following conversation.

W： Dan, you know the lab you missed? You can have my notes.

M： Thank you.

W ： So how are you feeling?

M： Much better now that I began taking an antibiotic. Students Health gave me one， and it’s really helpful. You know that it amazes me that the human races survive before antibiotics.

W： I agree. When my father was a young boy in the 1940's，he got blood poisoned and would have died. But his doctor had heard of this new drug，called penicillin.

M： (5) Wow，he was really lucky. And now we have lots of antibiotics that kill bacteria.

W： Well, (4) penicillin kills bacteria, but not all antibiotics do. Some just slow the bacteria down until our normal immune defenses can finish the job. Tetracycline works that way.

M： Wow, how do you know all these?

W： My mother used to look up all our medicines, prescription and nonprescription. There are lots of books around. It’s interesting. What antibiotic are you taking?

M： I don’t remember. It's on the bottle. (6) I think I'll take a new look at the label and drop by the library to see if they have any reference books on medicines. See you in lab tomorrow.

答案解析

Conversation 9

4. D主旨大意题。从对话中可以知道男士生病了，服用抗生素后，有了很大好转。他 对于人类能在抗生素发明之前幸存下来感到很吃惊。女士表示同意，她举了她父亲 的例子。她父亲年幼时曾经病危，但是他的医生听说了一种叫做盘尼西林的新药，从而挽救了他。然后女士谈到“盘尼西林能够杀死细菌，但并非所有的抗生素都这 样。一些只是降低了细菌的繁衍速度，直到我们的正常的免疫防御系统完成最终工 作。四环素就是这样”。这都与抗生素的特点有关，所以选择D。

5. C事实推理题。女士谈到自己父亲的经历。她的父亲年幼时曾经病危，但是他的 医生听说了一种叫做盘尼西林的新药，从而挽救了他。所以C项“强调抗生素的重 要性”为最佳答案。

6.  A细节题。在对话最后男士说他不记得服用的抗生素的名字，要重新看看药的标 签，然后去图书馆找找是否有相关的参考书，即A项“査阅他服用的药品的信息”。
