【答案解析】[听力原文]
W: So how are you feeling?
M: Much better now that I began taking an antibiotic. Student health gave me one, and it"s really help. You know what amazes me is that the human races survive before antibiotics.
W: I agree. When my father was a young boy in the 1940"s, he got blood poisoning and would have died. But his doctor had heard of this new drug, called penicillin.
M: Wow, he was really lucky. And now we have lots of antibiotics that kill bacteria.
W: Well, penicillin kills bacteria, but not all antibiotics do. Some are just slowing the bacteria down until our normal immune defenses can finish the job. Tetracycline works that way.
M: Wow, you are a fund of drug trivia. How do you know all these?
W: My mother used to look up all our medicines, prescription and non-prescription. There are lots of books around. It"s interesting. What antibiotic are you taking?
M: I don"t remember. It"s on the bottle. I think I"ll take a new look at the label and drop by the library to see if they have reference books on medicines. See you in lab tomorrow.
