Although man has known 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 he 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 on 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 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 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, soft, soapy fibers .
Scientists do not know why the rock can be separated easily into threads,but they have found thousands of uses of this fireproof material, of the so-called “cloth of stone”.

A. Asbestos mined in Canada B. Fireproof matter
C. A “wonder” mineral D. A new roofing material
61. Johns proved his ability as a salesman by_______.
A. going into roofing business
B. carrying asbestos from Italy
C. sending a trained scientist
D. showing the use of asbestos gloves
62. 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 burns easily. D. It is unusually heavy.
63. The author’s main purpose in writing this passage was to _______.

EARTH WEEK-A DIARY OF THE PLANETEnduring Storms

After years of unsuccessful attempts to keep crop-eating monkeys out of Japanese fields, a Tokyo research team believes that it may have finally found a way to prevent the damage caused by the monkeys. Animal raids on crops were successfully prevented by shooting chilli powder into the air, irritating the eyes and noses of monkeys that passed in front of carefully-placed warning sensors.“We’ve tried…all kinds of preventive measures, but the monkeys are smart enough to outwit the tricks,”said Toshiaki Wada, Director of the Tokyo Forestry Experiment Station in western Tokyo.

A. H. M. Farook, UNICEF’s operations area officer for China and Mongolia said that China “can be very satisfied to tell the whole world what can be done with limited resources to help its children to grow healthily and happily.”
China’s child population makes up one-fifth of the world’s total. “The reason behind the tremendous(巨大的) achievement is China’s long tradition of caring for children both at home and in society,” he said.
“What’s more is that Chinese people have always given special attention to children who are in special need.” The UN official made the remarks when addressing a group of 50 children and staff from the Beijing Children’s Welfare Home at the Shangri-la Hotel, Beijing.
The hotel invited the orphans to share snacks, sing, dance and play games at a park inside the hotel for a “Share the Sunshine” party, as a prelude(前奏) to celebrations to mark the Children’s Day.

A leading official of the welfare institution said that the children live a happy life and that the agency spends 400—500 yuan a month for an average orphan. An average Chinese workers earned 440 yuan a month during the first quarter this year.
Gu Xiaojin, deputy secretary-general of the China Youth Development Foundation(CYDF), said people from all walks of life have contributed to the welfare of the Chinese children.
She said that CYDF set up the Project Hope in 1989, which calls on people across the country to donate money to help poor children to continue their schooling.
By the end of last year, she said, CYDF had collected nearly 700 million yuan in donations, which has helped the establishment of 2, 074 Hope primary schools and enabled more than 1. 25 million dropouts to return to school classrooms.
Three “Hope Stars” also attended the party. They were model teenagers chosen among students who are economically supported by the Project Hope to further their nine-year compulsory studies in the poverty-stricken regions. They will be torchbearers for the Chinese Team for the up coming Atlanta Olympic Games this year.
