Section A
1.W：Dr.Brown，one of my best friends died of lung cancer yesterday.Does cancer have a high mortality？

Section B
Passage One
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 fnish 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.
Questions 16-20 are based on the conversation you have just heard.
16.What are the speakers mainly discussing？
17.What caused her father almost to die in the 1940’s？
18.Why does the woman tell the story about her father？

Passage Two
Let’s begin today by discussing enzymes.Enzymes are what make many of the body’s biochemical reactions possible.Actually biochemical reactions can take place without them，but at much lower rates. In fact an enzyme may cause a reaction to proceed billions of times faster than it would otherwise. Before I go on to the biochemical specifcs of how this works，let me provide a fgurative example.I think it will help illustrate the power of enzymes more clearly.Now，suppose you got a bag and you put a bunch of locks in it，just small padlocks.Then you put in all the keys that go with the locks.And you closed the bag and shook it hard.No matter how long you shook，chances are very small that any key would get inserted in any of the locks.But if you took them all out of the bag and this time used your hands to insert the keys in the locks，you could combine them much quicker.
Enzymes act like your hands，quickly allowing chemical reactions that would otherwise take much longer.Now，there are two reasons that enzymes are so effective at enabling biochemical reactions.First， enzymes greatly reduce the amount of energy required to start the reactions，and with less energy needed the reactions can proceed a lot faster than they could without the enzyme.The second reason is that a small amount of an enzyme is needed to enable the biochemical reaction.That’s because the chemical structure of the enzyme itself does not become altered as if enables the reaction.So a single enzyme can be used to start the same biochemical reaction over and over again.
Questions 21-25 are based on the passage you have just heard.
21.What is the passage mainly about？
22.What point does the professor make about an enzyme when it is involved in a biochemical reaction？
23.What do enzymes do to help start a biochemical reaction？
24.Why does the professor talk about locks and keys？
25.What is enzymes？
Passage Three
Many teachers believe that the responsibility for learning lines with the students.If a long reading assignment is given，instructors expect students to be familiar with the information in the reading even if they do not discuss it in class or give an examination.
The ideal student is considered to be one who is motivated to learn for the sake of learning， not the one interested only in getting high grades.When research is assigned，the professor expects the students to take the initiative and complete the assignment with minimum guidance.It is the students’responsibility to fnd books，periodicals and articles in the library.Professors do not have the time to explain how a university library works；they expect students，particularly graduate students，to be able to exhaust the reference sources in the library.
Professors will help their students who need it，but prefer that their students not be overly dependent on them.In the United States professors have other duties besides teaching.Often they are responsible for administrative work within their department.In addition，they may be obliged to publish articles and books.Therefore，the time that a professor can spend with a student outside of class is limited.If a student has problems with classroom work，the student should either approach a professor during offce hours or make an appointment.
