  要让人们相信鲨鱼不是人类的死敌不是一件容易的事。人们认为鲨鱼经常袭击人类。但鲨鱼在为地球水系和人类作着有价值的贡献。商业和捕鱼运动仍在威胁着他们的生存,有些鲨鱼面临着从地球上消失的危险。

  Warm weather may influence both fish and shark activity. Many fish swim near coastal areas   5  their warm waters. Experts say sharks may follow the fish into the same areas,   6  people also swim.

  温暖的气候影响着鱼类和鲨鱼的活动。由于水温变暖,很多鱼类游到海边。专家认为鲨鱼跟随其它鱼类,也来到人类游泳的区域。实际上鲨鱼并非故意袭击人类。人们认为,由于鲨鱼将人错认为是海狮等海洋动物,在饥饿时才袭击人类。日出和日落时,正是鲨鱼饥肠辘辘的时候,人们不应该出海游泳。专家还提到鲜艳的色彩和闪光的珠宝也会诱使鲨鱼袭击。

  鲨鱼的嗅觉特别灵敏,能嗅到海水中存在的极为微量的气味,比如血液、体液和动物散发的化学物质。灵敏的嗅觉有助于鲨鱼找到食物。鲨鱼以鱼、其他鲨鱼和海洋植物为生。

  14. A rivers B oceans C forests D mountains

  15. A weak B little C few D great

  答案与题解:

  1.A本题应选择attack,因为第一句说到:人们认为鲨鱼是a deadly enemy,也就是说鲨鱼会对人类造成伤害。第二句是对deadly enemy的具体说明。其他的三个选项meet,love,visit都不合适,love与上下文意思相反,meet和visit与上下文意思不符。

  2.C空格2所在的句子由but连接,所以该句子表达的意思一定与第二句相反。第二句对鲨鱼的评价是负面的,填入空格2的词应该是正面的。四个选项中只有valuable符合这一条件,所以是答案。

  3.B第三句说到鲨鱼有益于“waters and human beings”,第五句又说到鲨鱼濒临灭绝的危险。根据上下文的意思,threatening(威胁)到它们的应该是existence(生存)。其他的三个选项source,friends,fish都不合适,与上下文意思没有联系。

  4.D如果鲨鱼消失,从什么地方消失呢?当然从earth(地球)上消失。从space(宇宙空间)、sky(天空)中消失,或从land(陆地)上消失,都有悖常理。

  5.C四个选项的意思都是“因为“,但是从用法上分析,because、since和by reason that之后要接句子,because of之后接名词或名词短语。their warm waters是名词短语,所以要选用because of。

  6.D“…people also swim”明显是定语从句,其先行词是表示地点的名词area,所以要选关系副词where.。

  7.B从上下文判断,本句的意思是:鲨鱼将人错认为是海洋动物。而“将……错认为是”的英语表达是mistake…for,所以本题的答案是选项B。

  8.A本段的意思是:鲨鱼并非故意袭击人类。人们认为,由于鲨鱼将人错认为是海狮等海洋动物,在饥饿时才袭击人类。日出和日落时,正是鲨鱼饥肠辘辘的时候,人们不应该出海游泳。空格8填入的词应该与时间有关,所以times是答案,而与地点有关的选项(places seas和oceans)与上下文意思脱节。

  9.C本段第一、二句是说,鲨鱼的嗅觉特别灵敏,能嗅到海水中存在的极为微量的气味。作者举了三个物质:血、体液和化学品。空格9要填入表示物质的名词。四个选项中惟一表达物质的词是chemicals(化学品)。所以chemicals是答案,而其它三个选项与学科有关,脱离了上下文的意思,不是本题的答案。

  10.B在第一、二句意思的基础上,作者进一步说明,灵敏的嗅觉有助于鲨鱼找到食物。所以本题的答案是选项D的senses,因为feelings,touches和tastes都与smells无关。

  11.D 本句的中心词是复数的sharks,another所修饰的名词一般是单数,所以不会是答案。these和those是表特指的代词,指代前面出现过的名词。由于前面没有先行词,所以也不可能是答案。剩下的other是答案,any other sharks的说法也合乎英语的用法。

  12.A从上下文判断,医学研究人员想要更多了解的是“身体抗病system(系统)”,不会是 “身体抗病idea(思想)”、“身体抗病工作(work)”或“身体抗病circle(周期)”。

  13.A本段最后一句的意思是:医学研究人员研究鲨鱼的目的是为了找到一种人类抗病的方法。所以空格l3所在句子的意思应该是recover(quickly from injuries)。科学家想要探索的应该是有关受伤鲨鱼recover quickly from injuries的秘密,而reform(改造)、return(回归)和rely(依靠)只是与答案recover词形上有点相似而已,其意思与上下文的意思风马牛不相及。

  14.B 从上下文判断,鲨鱼的存在能使0ceans得益。鲨鱼不生活在rivers、forests或mountains中,所以,这三个选项不会是答案。

  15.D本段的其余三句都是说明为什么鲨鱼有益于海洋。它们吃海洋动物,结果使得海洋中的动物数量不会过多。weak、little、few都与上面表达的意思相反,所以,只有great是答案。
