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”.

Older people must be given more chances to learn if they are to contribute to society rather than be a financial burden, according to a new study on population published recently.
The current approach which 21 on younger people and on skills for employment is not 22 to meet the challenge of demographic (人口结构的) change, it says. Only 1% of the education budget is currently spent on the oldest of the population.
The 23 include the fact that most people can expect to spend a third of their lives in 24 , that there are now more people over 59 than under 16 and 11.3 million people are over state pension age.
“ 25 needs to continue throughout life. Our historic concentration of policy attention and resources on young people cannot meet the new 26 ” says the report’s author, Professor Stephen.
The major portion of our education budget is spent on people below the age of 25. When people are changing their jobs, home , partners and lifestyles more often than ever , they need opportunities to learn at every age. 27 , some people are starting new careers in their 50s and later.
People need opportunities to make a “midlife review”to 28 to the later stage of employed life and to plan for the transition (过渡) to retirement, which may now happen 29 at any point from 50 to over 90, says McNair.
And there should be more money 30 to support people in establishing a sense of identity and finding constructive roles for the “ third age”, the 20 or more years they will spend in healthy retired life.
