　　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”.

The vitamins necessary for a healthy body are normally supplied by a good mixed diet, including a variety of fruits and green vegetables. It is only when people try to live on a very restricted diet, say that when trying to lose weight, that it is necessary to make special provisions to supply the missing vitamins.

　　An example of the dangers of a restricted diet may be seen in the disease known as “beri-beri”, which used to make large numbers of Eastern people who lived mainly on rice suffer. In the early years of last century, a Dutch scientist named Eijkman was trying to discover the cause of beri-beri. At first he thought it was transmitted（传播）by a germ（病菌）. He was working in a Japanese hospital, where the patients were fed on polished rice which had had the outer coverings removed from the grain. It was thought this would be easier for weak and sick people to digest.

　　Eijkman thought his germ theory was proved when he noticed the chickens in the hospital yard, which were fed on remains from the patients’ plates, were also showing signs of the disease. He then tried to separate the germ, which he thought was causing the disease, but his experiments were interrupted by a hospital official, who ordered that the rice without coverings, even though left over by the patients, was too good for chickens. It should be recooked for the patients, and the chickens should be fed on cheap, rough rice with the outer coverings still on the grain.

　　Eijkman noticed that the chickens began to recover on the new diet. He began to consider the possibility that eating unmilled rice（糙米）somehow prevented or cured beri-beri — even that a lack of some ingredient（成分）in the coverings may be the cause of the disease. Indeed this was the case. The element needed to prevent beri-beri was shortly afterwards separated from rice coverings and is now known as vitamin B. The milled rice, though more expensive, was in fact causing the disease the hospital was trying to cure. Nowadays, this terrible disease is much less common thanks to our knowledge of vitamins.

Haisong Jiang, who slipped (偷偷溜进) past a security checkpoint(安全关卡) on Jan. 3, causing a shutdown of Newark Airport, tried to apologize for his mistake.
" I feel guilty about this serious mistake. At that moment, I was very excited with my girlfriend, and I didn't think too much," Mr. Jiang, 28, said Tuesday in his first interview since causing the six-hour shutdown at the airport.
On Tuesday, Newark Municipal Court judged that besides the community service, he must pay a $500 fine (罚金) and $158 in court fees. In an agreement between the court and Mr. Jiang's lawyer, Mr. Jiang will pay off his money punishment all by community service instead.
　　Haisong Jiang, a native of China, about a year ago moved to the United States in 2004 to study and met his girlfriend, also Chinese and 26. She has since moved to California.
The lovebirds did the town over the Christmas holidays: shopping in SoHo, visiting the tree at Rockefeller Center, celebrating New Year's Eve in Times Square - the works. On Jan. 3, he watched her pass through security, but he wanted to spend more time with her. When he noticed the officer leave his post, he saw his chance, he said. He slipped under the rope and kissed her and, arm in arm, walked her to her Continental Airlines gate and saw her onto the jetway. "And immediately I left," he said.
　　Three days passed. "Friday, the police found me," the future scientist said. He was at the gym when his roommate called to say two police officers were at their home. "It's not right to enter the airport. Immediately I know the police want to ask me this thing."
　  He expects to serve half of his community service in a soup kitchen - "I like to cook" - and the other half in a hospital. He plans on moving to California to be with her and work in a laboratory after completing his degree in May or June.
He never types his name into search engines on the Net: the number of hits is shocking.
What’s the best title of the passage?
A. A moving love story  B. An escape from security check

　　A scientist who developed a way to calculate(计算) how much water is used in the produciton of anything form a cup of coffee to a hamburger was awarded the 2008 Stockholm Water Prize.

　　Professor John Anthony Allan of the University of London in Britain won the award for introducing the idea of "virtual water(虚拟水)",a calculation method that has changed the nature of trade policy and research.

　　Allan has written seven books and published more than 100 papers.

　　The Stockholm International Water Institute said this idea is now embedded(埋藏) in the production of foods and industrial products.The institute said Allan's work had made a big effect on global trade policy and research,especially in water - scarce(缺水) regions.

　　"The improved understanding of trade and water management issues on local,regional and global scales are of the highest value for the successsful and sustainable(可持续的) use of water resources,"it said.

　　"People do not only use water when they drink it or take a shower,"the institute said. "Behind the morning cup of coffee,there are 140 liters of water that was used to grow,produce,package and ship the beans."That is about as much water as a person in England uses on average for all daily drinking and household needs.

　　"For a single hamburger,about 2,400 liters of water are needed.In te USA ,the average person uses nearly 7,000 liters of virtual water every day" It said that was more than three times the average use of a Chinese person.

　　64.Allan was awarded the prize because ______.

　　　A.he wrote seven books on trade policy

　　　B.he published more than 100 papers on water management

　　　C.he found a new kind of water in water - scarce areas

　　65.Which of the following is TRUE according to the passage?

　　　A.The average American uses about 7,000 liters of water a day.

　　　B.The average Chinese uses nearly 2,300 liters of virtual water a day.

　　　C.An Englishman usually drinks about 140 liters of coffee a day.

　　　D.A hamburger usually contains about 2,400 liters of water.

　　66.What effect does the idea of virtual water have?

　　　A.It helps us realize the importance of trade.

　　　B.It helps people do successful business.

　　　C.It helps us make use of water scientifically.

　　　D.It tells us how much water we use a day.

　　67.What does the underlined word "it" in the last paragraph refer to?

　　　A.The University of London.

　　　B.The calculation method.
