II. READING
Read the following passages and answer the questions about them. (15x2=30 pts.)
PASSAGE A
For several years, scientists have been testing a substance called interferon, a potential wonder drug that is proving to be effective in treating a variety of ailments, including virus infections, bacterial infections, and tumors. To date, the new drug has provoked no negative reaction of sufficient significance to discourage its use. But in spite of its success, last year only one gram was produced in the entire world.
The reason for the scarcity lies in the structure of interferon. A species specific protein, the interferon produced from one animal species cannot be used in treating another animal species. In other words, to treat human beings, only interferon produced by human beings may be used. The drug is produced by infecting white blood cells with a virus. Fortunately, it is so potent that the amount given to each patient per injection is very small.
Unlike antibiotics, interferon does not attack germs directly. Instead, it makes unaffected cells resistant to infection, and prevents the multiplication of viruses within cells.
As you might conclude, one of the most dramatic uses of interferon has been in the treatment of cancer. Dr. Hans Strander, research physician at Sweden’s famous Karolinska Institute, has treated more than one hundred cancer patient with the new drug. Among a group of selected patients who had undergone surgical procedures for advanced cancer, half were given conventional treatments and the other half were given interferon. The survival rate over a three-year period was 70 percent among those who were treated with interferon as compared with only 10 to 30 percent among those who had received the conventional treatments.
In the United States, a large-scale project supported by the American Cancer Society is now underway. If the experiment is successful, interferon could become one of the greatest medical discoveries of our time.
21. What is the difference between antibiotics and interferon?
a) Antibiotics are very potent, while interferon is not.
b) Antibiotics kill germs by attacking them directly, while interferon does not.
c) Interferon has serious side effects, whereas antibiotics do not.
d) Interferon is available in large supply, whereas antibiotics are not.
22. What effect does interferon have on infection?
a) It keeps healthy cells from becoming infected.
b) It provokes a negative reaction.
c) It attacks viruses.
d) It causes healthy cells to grow.
23. Interferon is produced by ……………… .
a) infecting viruses with proteins.
b) infecting white blood cells with a virus.
c) infecting proteins with a virus.
d) infecting viruses, bacteria, and tumors with a drug.
24. Interferon has not been more widely used because it is …………………. .
a) not effective in human beings.
b) not yet available in the United States.
c) difficult to produce in large quantities.
d) still very dangerous.
25. What were the results of Dr. Strander’s experiments with interferon?
a) Most of the patients who received interferon were still alive after three years.
b) Most of the patients who received interferon also needed conventional treatment.
c) At the end of three years, all of the patients who had not received interferon had died.
d) Half of the patients who received interferon reacted favorably.

a) negative reaction c) the entire world
b) interferon d) an ordinary drug

PASSAGE B
Supernovas are the most powerful and spectacular outbursts known in nature. What is called a Type II supernova is due to the collapse of a massive star, at least eight times as massive as the sun, that has used up its main nuclear fuel and produced a nickel-iron core. When this core can no longer support the pressure of the star’s outer layers, it collapses to form a neutron star of immense density. Over 2,500 million tons of neutron star material could be packed into a matchbox. Its temperature is around 100,000 million degrees centigrade. Multitudes of neutrons are produced in the collapsed star, which pass directly through the star into space, and this release of neutrons causes the core to respond with a shock wave that moves outward. When it meets the material that is falling inward, the result is a catastrophic explosion. Sometimes most of the star’s material is blown away, leaving only a small, incredibly dense remnant that may be a neutron star or, in extreme cases, a black hole.
A supernova is often more than 500 million times as luminous as the sun. A supernova remnant (SNR) may be detectable as a pulsar, an example of which is the Crab Nebula, known to be a remnant of the supernova observed in the year 1054. The 1987 supernova in the Large Cloud of Magellan had a low peak luminosity by supernova standards, only about 250 million times that of the sun. at its brightest the supernova shone as a star between magnitudes 2 and 3, even though it was 170,000 light-years away. .
