11、 warn19A.onBnearCawayDbesides20A.livesBlifeCliveDbelieves【答案解析】寒假作业18一.单项填空1.A考查名词词义辨析。potential可能(性)，潜力。2C句意为：布莱克先生是个细心而且有经验的工程师，因此他常常被委派去完成一些有挑战性的任务。appreciate感激；approach靠近，接近；appoint任命，委派；agree同意。3Bfit表示某物尺寸大小适合某人；suit表示某物颜色适合某人；be fit for表示“适合”。4Abe tired of sth.(人)厌烦/厌倦某事，在这里过去分词作状语；而boring用来修饰
12、speech，表示“令人讨厌的”。5A句意为：由于大火，他的房子被烧毁了，这使他无家可归。burn to the ground烧为平地；rebuild重建；run out of用完；paint粉刷。which引导非限制性定语从句，结合句意应选A项。6C句意为：我们正要给你打电话这时你来了。考查句型：be about to do.when.或be on the point of doing.when.，本题中因为后面是动名词形式，所以选C项。7B因I与work之间是主动关系，且非谓语动词所表示的动作在主句的谓语动词所表示的动作之前发生，故用现在分词的完成式作状语。8D句意为：当和整个地球的面积比
13、起来时，最大的大洋根本就不大了。the biggest ocean是句子的主语，与动词compare是动宾关系，因此要用过去分词。9C第一个空填got，与rushed和started一同作本句的谓语，表示一组相继发生的动作；第二空的hoping在句中作状语。10CAbsolutely not完全不可能，与语境相符。二.完形填空1.B从空后的“to tell whether a volcano.”看出科学家在寻找预测火山喷发的方法。glance一瞥；method方法；motor发动机；panic惊慌。2A从“will be small or large”看出要预言出火山喷发的规模大小。erupt
14、ion火山的爆发；climate气候；aspect方面；district区。3C从下文看出科学家在研究火山熔岩中的成分。lung肺部；ash灰烬；lava熔岩；crater火山口。4Dstate陈述；tease取笑；compare比较；do做。由空后的the research可知此处考查短语do the research“调查研究”。5A在某个月份用介词in。6D由and可知，此处应与“destroyed the homes of more than 2,000 others”相对应，应说have killed 43 people。quit停止；utter说，讲；focus以为重点/焦点。均与
15、句意不符。7A从still看出火山仍然是活跃的。active活跃的；abstract抽象的；ridiculous荒谬的；mental精神的。8D科学家说这种火山熔岩中包含大量的某种成分。try努力，尝试；manage经营，设法做到；stress压力；着重；contain包含。9Awhich引导一个非限制性定语从句。10Bcoming directly from inside the earth直接来自地球内部的。现在分词作后置定语。go，end和lose与句意不相符。11D直接来自地球内部的熔岩是与大规模的爆发有关的，而不是小规模的。be connected with与连接在一起，符合句意。d
16、ecrease减少；bored厌烦的；swallow吞咽。12Dduring thousands of years数千年间的。由空后的of可排除hundred和ten；由空前的many可排除C项。13A他们也研究其他火山的熔岩。also用于谓语动词之前。either用于否定句，too用于句末。14Cboth和and连用，表示“两者都”。其他三个选项不与and连用。15A从上文看出较大的火山爆发含有更多的该种成分。more.than.比更多。16Cones代替上文的explosions。that，those和this前不加形容词修饰。17B此处是与过去有关的虚拟语气的条件状语从句。谓语动词要用had done的形式。18B此处是与过去有关的虚拟语气的主句，谓语动词要用could have done的形式。其他三项不表示对过去的虚拟。19B此处指靠近火山。可用near也可以用beside，但不用besides。besides除了之外。20A挽救很多人的生命。life作“生命”讲时，是可数名词。由空前的many可知用复数lives。
