Ⅰ.阅读理解 While we were searching the heavens，science and all the corners of the Earth，the secret of immortality(永生) may have been floating in the ocean this whole time in the form of a jellyfish(水母)． Jellyfish start their lives as tiny cigar-shaped creatures that move in circles through the water，looking for a rock or something handy to attach itself to.Once firmly in place，they transform into polyps(水螅)，which are small creatures with a body shaped like a tube.When the conditions are right，these polyps bloom in large numbers and when they bloom，baby jellyfish are produced. If the start of jellyfish life wasn’t extraordinary enough，its death is where things get really exciting.When the medusa jellyfish dies，it sinks to the bottom and begins to die.Amazingly，its cells then reorganize，not into a new medusa，but into polyps，and from these polyps comes new jellyfish.The jellyfish has skipped to an earlier life stage to begin again.Dr.Lisa-ann Gershwin，a jellyfish researcher，says，“It’s one of the most amazing discoveries of our time.” It’s not just the medusa jellyfish that can rise from its own ashes.In 2011，a biology student in China kept a moon jellyfish in a tank.When it died，he kept the body in another tank.Three months later，a new tiny polyp was growing out the top of the moon jellyfish.This regeneration process has now been found in around five species of jellyfish. So aside from immortality，what’s the benefit for the jellyfish itself Why does it Well，it means when it becomes weakened either by age or illness，or it faces danger，it can call up its incredible survival mechanism and regenerate. Although Dr.Gershwin says she can’t see any link currently between jellyfish immortality and our own，it doesn’t mean it would not be possible in the future.Who knows A few jellyfish genes and we could all be like Doctor Who，regenerating whenever we want. 1．What do we know about jellyfish’s rebirth A．It brings jellyfish no benefits. B．It only occurs in four species. C．It goes through different life stages. D．It produces a new jellyfish directly. 2．Why is “a biology student in China” mentioned A．To introduce a new topic. B．To compare different study methods. C．To point out the limits of the view. D．To provide more evidence for the view. 3．What’s the author’s attitude to the future value of jellyfish’s immortality A．Positive. B．Negative. C．Doubtful. D．Unclear. 4．What’s the best title of the text A．The Secret of Immortality B．The Jellyfish That Never Dies C．The Process of Jellyfish’s Rebirth D．The Knowledge Obtained from Jellyfish 读写积累 1．handy adj.易使用的；容易做的；便利的；近便的 2．bloom熟义：n.(常指供观赏的)花；健康有精神的面貌 生义：v.开花(本文为此义)；变得健康/快活/自信 3．attach oneself to依附于…… 4．transform into转变成…… 5．aside from除……之外 6．call up叫醒，唤醒；给……打电话；使回忆起 7．...from these polyps comes new jellyfish. 句式结构：完全倒装 句子翻译：……从这些水 ... ...
