    14．To our relief，the new method finally provedto be a success．

    分析 令我们宽慰的是，新的方法最终证明是成功的

    解答 答案是proved；本题考查语境中选用适当的词；prove及物动词，证明…；连系动词，证明是…，常常用于prove （to be ）+adj/n．的结构中；题干中语境说明"证明是成功"发生在过去，故用过去时proved．

    点评 首字母填空必须在对语境整体理解的基础上抓住指向答案的关键线索、固定句型或搭配等，结合首字母选用恰当的词，同时注意所选词的形式变化．

    5．Most animals have little connection with animals of a different kind，unless they hunt them for food．Sometimes，however，two kinds of animals come together in a partnership （伙伴关系） which is good for both of them．You may have noticed some birds sitting on the backs of sheep．This is not because they want a ride，but because they find easy food in the parasites （寄生虫） on sheep．The sheep allow the birds to do so because they remove the cause of discomfort．So although they  can manage without each other，they do better together．
    Sometimes an animal has a plant partner．The relationship develops until the two partners cannot manage without each other．This is so in the corals （珊瑚） of the sea．In their skins they have tiny plants which act as"dustman"，taking some of the waste products from the coral and giving in return oxygen which the animal needs to breathe．If the plants are killed，or are even prevented from light so that they cannot live normally，the corals will die．

    21．Some birds like to sit on a sheep becauseA．
    A．they can eat its parasites
    B．they depend on the sheep for existence
    C．they enjoy traveling with the sheep
    D．they find the position most comfortable
    22．The underlined word"they"in the last sentence of the first paragraph refers to
    B．
    A．birds and parasites
    B．birds and sheep
    C．parasites and sheep
    D．sheep，birds and parasites
    23．We learn from the text that the coral depends on the plant forD．
    A．comfort        B．light          C．food         D．oxygen
    24．What does the second paragraph mainly discuss？A
    A．Some animals and plants depend on each other for existence．
    B．Some animals and plants develop their relationship easily．
    C．Some plants depend on each other for food．
    D．Some animals live better together．

    2．Think about the different ways that people use wind．You can use it to fly a kite or to sail a boat．Wind is one of our cleanest and richest power sources，as well as one of the oldest．Evidence shows that windmills（风车） began to be used in ancient Iran back in the seventh century BC．They were first introduced to Europe during the 1100s，when armies returned from the Middle East with knowledge of using wind power．
    For many centuries，people used windmills to grind（磨碎） wheat into flour or pump water from deep underground．When electricity was discovered in the late 1800s，people living in remote areas began to use them to produce electricity．This allowed them to have electric lights and radio．However，by the 19 40s when electricity was available to people in almost all areas of the United States，windmills were rarely used．
    During the 1970s，people started becoming concerned about the pollution that is created when coal and gas are burned to produce electricity．People also realized that the supply of coal and gas would not last forever．Then，wind was rediscovered，though it means higher costs．Today，there is a global movement to supply more and more of our electricity through the use of wind．
    28．From the text we know that windmillsC
    A．have rarely been used since electricity was discovered
    B．have a history of more than 2，800 years
    C．used to supply power to radio in remote areas
    D．were invented by European armies
    29．What was a new use for wind power in the late 19gh century？C
    A．Sailing a boat．
    B．Grinding wheat into flour．
    C．Producing electricity．
    D．Pumping water from underground．
    30．One of the reasons wind was rediscovered in the 1970s is thatB
    A．it is one of the oldest power sources
    B．wind power is cleaner 
    C．it was cheaper to create energy from wind
    D．the supply of coal and gas failed to meet needs
    31．What would the author probably discuss in the paragraph that follows？

    B．The global trend towards producing power from wind．
    C．The worldwide movement to save energy．

    5．Something FunA person is on trial for murder in a court room in Oklahoma．There is strong evidence indicating guilt．However，the body is not found．
    In the defense's（辩护）closing statement，the lawyer，knowing that his client is guilty and that it looks like he'll probably be convicted，resorted to a clever trick．
    "Ladies and gentlemen of the jury（陪审团），I have a surprise for you all，"the lawyer says as he looks at his watch．"Within one minute，the person assumed dead in this case will walk into this court room，"he says and he looks towards the court-room door．The jury，somewhat surprised，looks at the door eagerly．A minute passes．Nothing happens．
    Finally the lawyer says，"Actually，I made up the previous statement．But you all waited with expectation．I，therefore，put it to you that there is a reasonable doubt in this case as to whether anyone was killed and insist that you return a verdict（裁决）of no guilty．
    The jury，clearly confused，retires to discuss．
    A very few minutes later，the jury returned and a representative pronouns a verdict of guilty．
    "But how？"inquires the lawyer．"You must have had some doubt； I saw all of you stare at the door．"
    Answers the representative，"Oh，we did look．But your client didn't．"

    24．Why was the person on trial according to the passage？B
    A．Because he couldn't pay off the debts．
    B．Because he was accused of murder．
    C．Because he did not pay the tax in time．
    D．Because he planned to cheat the jury．
    25．Why did the lawyer come up with the trick？C
    A．To find the body．
    B．To annoy the jury．
    C．To help his client．
    D．To save himself．
    26．Why did the jury look at the door eagerly？C
    A．The lawyer's words must be true．
    B．They expected his family to come in．
    C．They were surprised and taken in by the lawyer．
    D．They thought the person on trial was escaping．
    27．What did the representative's answer mean in the last paragraph？B
    A．They firmly believed that nobody was killed．
    B．The behavior of the client gave him away．
    C．The jury still needed more evidence to prove it．
    D．The lawyer's words were worth thinking about．
