In 1957 a doctor in Singapore noticed that hospitals were treating an unusual number of influenzalike cases. Influenza is sometimes called “flu”or a “bad cold”. He took samples from the throats of patients in his hospital and was able to find the virus（病毒）of this influenza.

There are three main types of influenza virus. The most important of these are types A and B, each of them having several sub-groups（亞群）. At the hospital the doctor recognized that the outbreak was because of a virus group A, but he did not know the sub-group. He reported the outbreak to the World Health Organization in Geneva. W. H. O. published the important news together with reports of the same kind of outbreak in Hong Kong, where about 15％～20％ of the population had become ill.

As soon as the London doctors received the package of throat samples, they began to test them. They found that they could reproduce themselves at a very high speed. Continuing their careful tests, the doctor checked the effect of medicine used against all the known sub-groups of type A virus. On this virus, none of them was of any use.

Having separated the virus, the two doctors now made tests on some selected seleceted animals. In a short time the usual signs of the disease appeared. These experiments showed that the new virus spread easily, but that it was not a killer. Scientists, like the general public, called it simply “Asian flu”.

72. The Asian flu mentioned in the passage ____.     

A. had something to do with a virus group B

B. was reported to W. H. O in Geneva by a doctor in Hong Kong

C. broke out not only in Singapore but also in Hong Kong

D. was taken from the throats of the patients in a hospital in Singapore

73. London doctors considered ____.

A. Asian flu as a bad cold

B. there were three main types of influenza

C. it was necessary to test the other groups of virus besides group A

D. the influenza called “Asian flu”a new one

74. The Singapore doctor helped the world by ____.   

A. making those with Asian flu well again   B. killing the virus that caused Asian flu

C. finding the sub-group of the virus       D. reporting the outbreak of Geneva

75. The Asian flu virus ____.      

A. was a killer   B. was very weak   C. could reproduce very quickly   D. died very fast

   Although man has known about asbestos for many hundreds of years, it was not until 160 years ago that it was mined for the first time on the North American continent. H. W. Johns, owner of a New York City Supply Shop for roofers, was responsible for （對……負(fù)責(zé)）the opening of that first mine.

   Mr. Johns was given a piece of asbestos which had been found in Italy. He experimented with the material and then showed its surprising powers to his customers. After putting a pair of asbestos gloves, which looked much like ordinary work gloves, he took red-hot coals from the fireplace and played with them in his hands. How astonished the customers were to discover that he was not burned at all. You can well imagine that he had increasing business in asbestos roofing materials. However, because it was very expensive to transport(carry) them from Italy to the United States, Mr. Johns sent out a young scientist to seek a source nearer home. This young man found great vein（巖脈）

in the province of Quebec in Canada.

   Ever since 1881, Quebec has led the world in the production of this unusual mineral, which is made up of magnesium, silicon, iron, and oxygen. When it is mined, the asbestos is heavy, just as you would expect a mineral to be. When it is separated, a strange thing happens: the rock breaks down into fine, soapy fibers（滑膩的纖維）。

    Scientists do not know why the rock can be separated easily into threads（線）,but they have found thousands of uses for this fireproof material, often called the “cloth of stone”.

1. The title that best expresses the main idea of the passage is _____.

   A. Asbestos mined in Canada          B. Fireproof matter

   C. A “wonder” mineral               D. A new roofing material

2. Johns proved his ability （能力）as a salesman by_____.

going into the roofing business

carrying asbestos from Italy

sending a trained scientist

showing the use of asbestos gloves

3. Which is the most important character of asbestos that the author wants to show us?

   A. It is like thread               B. It feels soapy

   C. It bums easily                D. It is unusually heavy

4. The author’s main purpose in writing this passage is to______.

show the need for more scientists

compare asbestos with other minerals

increase the sales of asbestos

present facts about asbestos
