  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”.

    Bobby was sitting out in his back yard in the snow. The thin sneakers he wore had a few holes in them. Try as he might, he could not come up with an idea for his mother’s Christmas gift.

    Ever since his father had passed away three years ago, his mother worked nights at the hospital, but the small wage could only be stretched so far.

    What the family lacked in money and material things, they more than made up for in love and family unity. They ran the household in their mother’s absence. All three of his sisters had already made beautiful gifts for their mother.

    It was Christmas Eve already, and he had nothing. Bobby started to walk down to the street. He walked from shop to shop. Everything seemed so beautiful and so out of reach. It was starting to get dark, then suddenly his eyes caught a shiny dime. Never has anyone felt so wealthy as Bobby did at that moment.

    He went inside a flower shop. When the owner asked if he could help him, Bobby presented the dime and asked if he could buy one flower. The shop owner looked at Bobby, then said, “You just wait here and I’ll see what I can do for you.”

    The shop owner returned holding red roses all tied together with a big silver bow. Bobby’s heart sank as the owner placed them gently into a long white box. “That will be ten cents, young man,” said the shop owner, reaching out his hand for the dime. Slowly, Bobby moved his hand to give the man his dime.

    Then the shopkeeper’s wife appeared. “Where are the roses you were fixing?”

    The shop owner replied, “A strange thing happened to me this morning. I thought I heard a voice telling me to set aside a dozen of my best roses for a special gift. I wasn’t sure at the time whether I had lost my mind or what, but I set them aside anyway. When I saw that little boy tonight, I knew who that voice was.”

阅读下列短文,从每题所给的四个选项(A、B、C和D)中选出最佳选项。

  Ever since they were first put on the market in the early 1990s, genetically modified(GM, 转基因)foods have been increasingly developed and marketed in many countries in the world, mainly on the basis of their promise to end the worldwide food crisis.But can GM technology solve world hunger problems? Even if it would, is it the best solution?

  Despite what it promises, GM technology actually has not increased the production potential of any crop.In fact, studies show that the most widely grown GM crop, GM soybeans, has suffered reduced productivity.For instance, a report that analysed nearly two decades of research on major GM food crops shows that GM engineering has failed to significantly increase US crop production.

  Something else, however, has been on the rise, While GM seeds are expensive, GM companies tell farmers that they will make good profits by saving money on pesticides(杀虫剂).On the contrary, US government data show that GM crops in the US have produced an overall increase in pesticide use compared to traditional crops.“The promise was that you could use less chemicals and boost production.But neither is true, ” said Bill Christison, President of the US National Farm Coalition.

  At the same time, the authors of the book World Hunger: Twelve Myths argue that there actually is more than enough food in the world and that the hunger crisis is not caused by production, but by problems in food distribution and politics.These indeed deserve our efforts and money.Meanwhile, the rise in food prices results from the increased use of crops for fuel rather than food, according to a 2008 World Bank report.

  As a matter of fact, scientists see better ways to feed the world.Another World Bank report concluded that GM crops have little to offer to the challenges of worldwide poverty and hunger, because better ways out are available, among which “green” farming is supposed to be the first choice.
