    阅读理解

    　　April 6, 2005 BERLIN-It has led to numerous expeditions, several mysterious deaths and plenty of books．But 60 years after Nazi officers hid metal boxes in the depths of Lake Toplitz, a new attempt is being made to recover the Third Reich's fabled(传说中的)lost gold．The Austrian government has given a U．S．team permission to make an underwater expedition to the bottom of the lake．

    　　Groups of treasure hunters have been racing to Lake Toplitz ever since a group of diehard Nazis escaped to this picturesque part of the Austrian Alps in the final months of the Second World War．With U．S．troops closing in and Germany on the edge of collapse(垮台), they shipped the boxes to the bank of the lake, and sunk them．

    　　Nobody knows exactly what was inside．Some believe the boxes contained gold stolen by German troops throughout Europe and carried back to Germany．Others think that they contained documents showing where possessions confiscated(没收)from Jewish victims were hidden．The state company that controls the lake, Bundesforste AG, has signed a contract with Norman Scott, an American treasure hunter, who hopes to solve the mystery．

    　　Later this month, Scott will begin a detailed underwater expedition of the 350-foot-deep lake, though there is official doubt that there is anything left to find．“I really don't know if there is anything down there, but we want to resolve the mystery once and for all,”Irwin Klissenbauer, a director of Bundesforste AG, told the Guardian Tuesday．“The aim at first is to measure the lake．”He added：“This is a beautiful area．You have heard of Loch Ness．For Austrians this has been a bit like Loch Ness．Lots of people come here．And whether there is gold down there or not, the mystery has been very good for tourism．”

    　　Klissenbauer said that under the terms of the deal--which allows the U．S．team to dive for the next three years-any treasure found will be divided between the Americans and the Austrian state．“Obviously if they recover anything which has a recognizable owner, under Austrian law we have to give it back．”

    (1)

    Which is the best title of the passage?

    [　　]

    A．

    Unsolved Mystery

    B．

    Treasure Found

    C．

    Mysterious Lake

    D．

    New Discovery

    (2)

    What can we infer from the passage?

    [　　]

    A．

    Many books about mysterious deaths have been written so far．

    B．

    Treasure hunters never risked searching the lake for gold until now．

    C．

    Many books have been written about mysteries hidden in the Lake．

    D．

    Norman Scott is sure there is nothing left to find in the lake．

    (3)

    Norman Scott will make the underwater expedition mainly to ________．

    [　　]

    A．

    find evidence proving Nazi Germany's cruelty

    B．

    help measure the beautiful lake

    C．

    uncover the mystery in the lake

    D．

    help people get back their possessions

    (4)

    According to Austrian law and the deal reached by the Americans and the Austrian government, ________．

    [　　]

    A．

    the U．S．team is to solve the mystery in the next three years

    B．

    both sides will take part in the underwater expedition

    C．

    any treasure found will go to either the Americans or the Austrian government

    D．

    people might get their treasure back if there~ re proofs of their ownership

    B
    When people lose legs after accidents or illnesses, emergency care and artificial limbs（假肢）often allow them to walk again. Newts （蝾螈） in the same situation, on the other hand, can grow limbs back on their own! Scientists have known for a long time that certain animals can re-grow limbs, but they haven’t quite figured out how these creatures do it.
    Researchers have now come up with some new ideas. Their work may give people the ability to re-grow lost limbs. The researchers started with two simple experiments：when you cut a newt’s leg at the ankle, only the foot grows back；when you cut off a leg at the very end, the whole leg grows back. In both cases, the re-growth begins with stem cells. Stem cells can develop into nearly any type of cell in the body.
    How do a newt’s stem cells know when to grow only a foot and when to re-grow a whole leg?
    This question relates to another mystery. In newt’s, a cut-off leg will grow back only if the nerve bundle（神经束）in it also grows back , but if something prevents the nerve bundle from growing, the stem cells at the wound won’t re-grow a new leg.
    In its study, a British team focused on a protein called n-AG. When the team prevented nerves in a limb from growing, but added the n-AG protein to stem cells in the limb, the limb still re-grew. That protein seems to guide limb re-growth. People have proteins that are similar to n-AG. Further research into these materials may someday help human limbs recover by themselves.
    40. In the experiments, the researchers cut off a newt’s foot or leg to find out _____.
    A. what stem cells were                     B. whether they would grow back
    C. how long it would take to re-grow    D. how they would re-grow
    41. A newt will re-grow its leg if _____.
    A. its ankle was cut off but the nerve bundle was good
    B. its leg was cut off and the nerve bundle stopped growing
    C. its leg was cut off and the nerve bundle could grow back
    D. its ankle and the nerve bundle were cut off
    42. What do the underlined words “these materials” refer to?
    A. Nerve bundles and proteins.         B. Proteins similar to n-AG.
    C. Stem cells and proteins.               D. Stem cells and nerve bundles.
    43. The first sentence of the passage _____.
    A. acts as a lead–in                       B. shows where researchers got their new ideas
    C. states the author’s opinion           D. describes the result of researchers’ studies
