Passage 1
Every year scientists open more doors that lead to the crets of
new beneficent drugs.
There is bacitracin, which was discovered by two scientists at
Columbia University's College of Physicians and Surgeons. The two
people, Dr. Frank Meleney and Miss Balbina Johnson, knowing that the
human body had some kind of action in itlf with which it fights
infections, began to arch for the chemical that does this. In the
hospital they examined badly infected wounds of people who had been
hurt in accidents and made tests of the blood and the infected tissue.
Finally, in the wound of a girl who had broken a leg bone, they
found the uful germs which emed to be fighting the poisonous
infection. They took some of the into the laboratory and from them
developed cultures; that is, larger mass of the germs with which to
experiment. At last, after long and painstaking work, they were able
to draw from the germs a substance which is a germ destroyer. Dr.
Meleney and Miss Johnson named it bacitracin-baci becau the germ is,
in scientific language, a bacillus and tracin for Margaret Tracy,
who broken leg supplied the germ.
Bacitracin at first was ud only locally; later the drug was
developed into a solution that can be ud to fight germ through the
blood stream.
16.Today, the discovery of a new drug occurs .
A)very ldom. B)once in a generation.
C)once every ten years. D)frequently.
17. The scientific term for the action with which the human body
fights infection .

A)fresh wounds. B)infected wounds.
C)only infected leg bones. D)only a few wounds.
19. Cultures, as ud in this article, are .
A)mass of germs.
B)blood tests.

D)poisonous germs.
20. Bacitracin .
A)is poisonous. B)destroys germs.
C)restores broken bones. D)develops germs.
21. To say that a drug was ud locally is to say that it was .
A)distributed through the whole system.
B)ud only in the area of infection.
C)ud only at Columbia
D)ud only in hospitals.
22. From reading this lection you can infer that
A)many scientific discoveries are due to chance.
B)every year scientists discover new beneficent drugs.
C)behind medical discovery there may be a dramatic story.
D)culture are large mass of germs.
Passage 2
Our echo sounder located the wreck of a French submarine that had
foundered during the war in venty-five feet of water outside Dakar
harbor. Dumas and I plunged down and found the vesl lying clean and
upright, surrounded by such clouds of fish as we had rarely en-small
silver fingerlings and dark metals. As Dumas swam into the shadow of
the port propeller, he came face to face with a gigantic fish, grouper
variety, cousin to our familiar Mediterranean meroblast-fish. This
specimen was ten times the size of our old acquaintances: he weighed
at least four hundred pounds. The wide, flat head and tiny eyes
advanced on Dumas; the ugly mouth yawned open, wide enough to admit
him. Dumas knew that dentary groupers have no teeth to speak of; it
emed, however, that this individual might wish to swallow him
unmasticated in the fashion of the mero type which swims agape(大张着嘴),
taking in whole octopus（章鱼）.
