    2．In the late 1950s，a Russian geneticist called Dmitry K．Belyaev attempted to create a tame （驯化的） fox population．Through the work of a breeding programme at the Institute of Cytology and Genetics at Novosibirsk，in Russia，he sought to find the evolutionary pathway of tame animals．His test subjects were silver-black foxes，a melanistic （带黑色的） version of the red fox that had been bred in farms for the color of their fur．
    He selected the animals based on how they responded when their cage was opened．About 10% of the foxes displayed a weak"wild-response"，meaning they were docile around humans．Those that hid in the comer or made aggressive voices were left in the farm．Of those friendly foxes，100females and 30males were chosen as the first generations of parents．
    When the young foxes were born，the researchers hand-fed them．They also attempted to touch or pet the foxes when they were two to two-and-a-half months old，for strictly measured periods at a time．If the young foxes continued to show aggressive response，even after significant human contact，they were thrown away from the population---meaning they were made into fur coats．In each selection，less than 10% of tame individuals were used as parents of the next generation．
    By the fourth generation，the scientists started to see dramatic changes．The young foxes were beginning to behave more like dogs．They wagged their tails and"eagerly"sought contact with humans．By 2005-2006，almost all the foxes were playful，friendly and behaving like domestic dogs．The foxes could"read"human hints and respond correctly to gestures or glances．

    28．What do we know about Belyaev's breeding plan？B
    A．It explains how red foxes were bred．
    B．It focuses on how tame animals evolved．
    C．It explains why pet foxes became popular．
    D．It concentrates on why tame animals disappeared．
    29．How did he choose his test foxes in the experiment？C
    A．By appearance．
    B．By color．
    C．By reaction．
    D．By flexibility．
    30．What can be inferred from Paragraph 3？C
    A．Smart foxes were used for testing．
    B．The purpose of selection was unclear．
    C．Friendly foxes were kept on testing．
    D．The selection was not exact and thorough．
    31．What is the distinguishing characteristic of the fourth generation foxes？A
    A．Behaving in a friendlier way．
    B．Eating plants．
    C．Having drooping ears．
    D．Having shortened legs．

    3．Move Earth-It's Not Science FictionLONDON-Scientists have found an unusual way to prevent our planet from overheating：move it to a cooler spot．All you have to do is send a few comets（彗星）in the direction of Earth，and its orbit will be changed．Our world will then be sent spinning into a safer，colder part of the solar system．
    This idea for improving our climate comes from a group of US National Aeronautics and Space Administration （NASA） engineers and American astronomers．They say their plan could add another six billion years to the useful lifetime of our planet-effectively doubling its working life．
    The plan put forward by Dr．Laughlin，and his colleagues Don Kory can sky and Fred Adams，needs carefully directing a comet or asteroid （小行星）so that it passes close by our planet and sends some of its gravitational energy to Earth．
    "Earth's orbital speed w ould increase as a result and we would move to a higher orbit away from the Sun，"Laughlin said．
    Engineers would then direct their comet so that it passed close to Jupiter or Saturn．The comet would pick up energy from one of these giant planets．Later its orbit would bring it back to Earth，and the process would be repeated．
    In the short term，the plan provides an ideal way to global warming，although the team was actually concerned with a much greater danger．The Sun is certain to heat up in about a billion years and so"seriously compromise"our biosphere（生物圈）-by cooking us．
    That's why the group decided to try to save Earth．
    The plan has one or two worrying aspects，however．For a start，space engineers would have to be very careful about how they directed their asteroid or comet towards Earth．The smallest miscalculation（误算）in orbit could fire it straight at Earth-with deadly results．
    There is also the question of the Moon．As the current issue of Scientific American magazine points out，if Earth was pushed out of its current position，it is"most likely the Moon would be stripped away from Earth"．This would greatly change our planet's climate．

    67．What makes the scientists plan to move Earth？C
    A．A few comets are moving to the direction of Earth．
    B．Earth's working life is coming to an end soon．
    C．Earth will become too hot for mankind to keep alive．
    D．The moon is moving farther and farther away from Earth．
    68．If the plan is successful，Earth will have a working life ofAyears．
    A.12 billion　B.6 billion　C.18 billion　D.24 billion
    69．What serious problems might the plan cause according to the passage？A
    A．The comet might hit Earth and man might lose the Moon．
    B．Earth might be moved too far away and man might be frozen to death．
    C．The comet might hit Jupiter or Saturn and never return to Earth．
    D．Earth's working life might be greatly shortened．
    70．What does the underlined word"compromise"mean？D
    A．Surround．B．Benefit．C．Share．D．Endanger．
