    What would be the best title for the passage ? A.Pollution saying goodbye to the world. B.Iceland becoming a country without oil C.Iceland planning to turn water into fuel D.Man able to kick the oil habit C All over the world , libraries have begun the Herculean task of making faithful digital copies of the books , images and recordings that preserve the intellectual effort of mankind. For armchair schools,the work promises to bring such a wealth of information to desktop that the present Internet may not match . Librarians see three clear benefits to going digital. First ,it helps them preserve rare and fragile objects without refusing the demands of those who wish to study them . The British Library, for example, holds the only medieval manuscriptof Beowulf in London . Only qualified scholars were allowed to see it sources and put the images up on the Internet for anyone to use. A second benefit is convenience. Once books are changed to digital form, readers can find them in seconds rather than minutes. Several people can read the same book or view the same picture at the same time . Clerks are spared the chore of reshelving . And libraries could use the Internet to lend their collections to those who are unable to visit in person. The third advantage of electronic copies is that they occupy millimeters of space on a magnetic disk rather than meters on a shelf . The cost of library buildings is increasingly high. The University of California at Berkeley recently spent $46 million on an underground addition to house 1.5 million books –an average cost of $30 per volume. The price of disk storage on the contrary, has fallen to about $2 per 300-page publication and continues to drop. 【查看更多】

     

    题目列表(包括答案和解析)

       Iceland has energy to spare, and the small country has found a cutting-edge(尖端的) way to reduce its oil dependency. Volcanoes formed the island nation out of ash and lava(熔岩), which heat huge underground lakes to the boiling point. The hot water is piped into cities providing heat for homes, businesses and even swimming pools. The water runs through turbines(涡轮机), providing all the country’s electricity.

       Iceland wants to make plans to improve its cars, buses and trucks to run on renewable energy. Iceland has already started by turning water into fuel ----hydrogen(氢) fuel. Here’s how it works: Electrodes (电极) change the water into hydrogen and oxygen molecules(分子). Hydrogen electrons pass through a conductor that creates the current to power an electric engine.

       Hydrogen fuel now costs two to three times as much as gasoline, but gets up to three times the distance than gas, making the overall cost about the same. As an added benefit, there is no carbon(碳) ----only water steam.

       In the capital, Reykjavik, they are already testing three hydrogen-powered electric buses. The drivers are impressed. “I like these buses better because with hydrogen you get no pollution,” said bus driver Rognvaldur Jonatanison. By the middle of this century, all Icelanders will be required to run their cars only on hydrogen fuel, meaning no more gasoline.

    　　“If we make hydrogen and use that as a fuel for transportation then we can run the whole society on our own local renewable energy sources,”said Marie Mack. Icelanders are showing the world that by making fuel from water, it is possible to kick the oil habit.

     

    57. From Paragraph 1 we may infer that ________.

    A. Iceland lacks natural resources           

    B. volcanoes do more good than harm to Iceland

    C. Iceland only depends on oil for energy     

    D. Iceland’s electricity is made from coal

    58. Which of the following is necessary during the period of turning water into fuel according to Paragraph 2?

       A. Lava               B. Electric engine        C. Conductor         D. Turbine

    59. The cars with hydrogen as fuel ________.

    A. are environmentally friendly                   B. are cheaper

        C. run much faster                                     D. will make useful steam

    60. What would be the best title for the passage?

    A. Pollution saying goodbye to the world.    

    B. Iceland becoming a country without oil

    C. Iceland began to turn water into fuel
