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）。

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

The baby monkey is much more developed at birth than the human baby. Almost from the moment it is born, the baby monkey can move around and hold tightly to its mother. During the first few days of its life the baby will approach and hold onto almost any large, warm, and soft object in its environment, particularly if that object also gives it milk. After a week or m, however, the baby monkey begins to avoid newcomers and focuses its attentions on “mother" 一 the real mother or the mother-substitute (母亲替代树).

During the first two weeks of its life warmth is perhaps the most important psychological (心理的) thing that a monkey mother has to give to its baby. The Harlows, a couple who are both psychologists, discovered this fact by offering baby monkeys a choice of two types of mother-substitutes 一 one covered with cloth 4nd one made of bare wire. If the two artificial mothers were both the same temperature, the little monkeys always preferred the cloth mother. However, if the wire model was heated, while the cloth model was cool, for the first two weeks after birth the baby monkeys picked the warm wire mother-substitutes as their fuvorites. Thereafter they switched and spent most of their time on the mw comfortable cloth mother.

Why is cloth preferable to bare wire? Something that the Harlows called contact (接級) comfort seems to be the answer, and a most powerful influence it is. Baby monkeys spend much of their time rubbing against their mothers' skins, putting themselves in as close contact with the parent as they can. Whenever the young animal is frightened, disturbed, or annoyed, it typically rushes to its mother and rubs itself against her body. Wire doesn't “rub" as well as does soft cloth. Prolonged (长时间的) “contact comfort" with a cloth mother appears to give the babies confidence and is much more rewarding to them than is cither warmth or milk.

According to the Harlows, the basic quality of baby’s love for its mother is trust. If the baby is put into an unfamiliar playroom without its mother, the baby ignores the toys no nutter how interesting they might be. It screams in terror and curls up into a furry little ball. If its cloth mother it now introduced into the playroom, the baby rushed to it and holds onto it for dear life. After a few minutes of contact comfort, it obviously begins to feel more secure. it then climbs down from the mother-substitute and begins to explore the toys, but often rushes back for a deep embrace (拥抱) as if to make sure that its mother is still there and that all is well. Bit by bit its fears of the new environment are gone and it spends more and more time playing with the toys and less and less time holding onto its “mother.”

50. Psychologically, what does the baby monkey desire most during the first two weeks of its life?

A. Warmth.             B. Milk.                C. Contact.            D. Trust.

51. After the first two weeks of their life, baby monkeys prefer the cloth mother to the wire mother because the former is ______.

A. larger in size                                     B. closer lo them

C. less frightening and less disturbing      D. more comfortable to rub against

52. Whal docs the baby monlcry probably gain from prolonged Mcontact comfort"?

A. Altenlion.                                        B. Softness.

C. Confidence.                                     D. Interest.

53. It can be inferred that when the baby monkey feels sccure, ______.

A. it frequently niftheft back for a deep embrace when exploring the toys

B. it spends more time screaming to get rewards

C. il is less attracted to the toys though they are interesting
