   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 (对……负责)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(岩脉)

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(滑腻的纤维)。

阅读下列短文,从每题所给的四个选项中,选出最佳答案

I realized now that the refrigerator overheard our talk. The very next day it went wrong. The repairman told us we needed a new unit. Cost:$600. Not long after that, we got a refund(赔偿金)from the shop, enough to pay for a trip to Mexico. “I’ve something to tell you,” I said to my wife in a low voice. “How about the living-room?” she suggested. I remembered the color TV set was there. “No, not there. Let’s go out.” I showed her the check as we stood on the driveway. We held each other excitedly and hardly noticed the rain. My car was parked within5 meters. I didn’t think anything about it at the time. As I started for the airport the next day, the car began making strange sounds. Changing the engine cost about $ 1, 000.

Then I looked through our financial records. I discovered that during the last ten years we spent all our “found money” repairing a hot water heater, a television and a stove.
