  答案与解析

  2015年真题答案

  51.A。本题考查名词。一个__________ 就是一个平台,能够垂直和在空中盘旋 __________直升机。根据前一句,安全专家正在设计新的方法来从起火的摩天大楼里救人,因为本句中谈论的是方法之一,故A(主意,想法)为正确答案。

  52.C。本题考查词义辨析。题干:一个想法就是一个平台,能够垂直和在空中盘旋__________ 直升机。四个选项为近形词,其中silk意为“丝绸”,unlike意为“与……不同”,like意为“喜欢:像”,likely意为“可能的”,从此处的语境来看,能垂直和在空中盘旋的就是直升机,故C为正确答案。

  53.B。本题考查动词。题干:这个平台能够沿着摩天大楼上升和下降,从而可以接起 __________高层中的人们。四个选项分别代入后,(be)trapped in意为“受困于……之中,陷入……之中”比较符合语境,因为文章讨论的就是摩天大楼起火后如何救人的事情,故B为正确答案。

  54.B。本题考查动词。题干:Metreveli的设计__________ “鹰”,需要两个喷气式发动机,从而能够__________ 四个较大的水平螺旋桨。根据语境,此处的句意Metreveli的设计起名叫“鹰”,故该题答案选B。

  55.C。本题考查动词。题干:Metreveli的设计起名为“鹰”,需要两个喷气式发动机,从而能够__________ 四个较大的水平螺旋桨。四个选项代入后,turn the four large horizontal propellers(转动四个水平螺旋桨)比较符合语境,所以该题的答案为C。

  56.D。本题考查动词。题干:螺旋桨的旋转__________ 必要的举起或者向上的力量来将平台升高。四个选项分别代入后,9eneratethenecessaryupwardforce(产生必要的向上的动力)比较符合语境,故D为正确答案。

  57.A。本题考查名词。题干:越多的__________ 提供给螺旋桨,那么平台就__________ 越高。根据语境,螺旋桨的转动肯定需要动力,故A为正确答案。

  58.B。本题考查动词。题干:越多的动力提供给螺旋桨,那么平台就__________ 越高。根据语境,螺旋桨的旋转产生必要的举起或者向上的力量来将平台升高,所以越多的动力提供给螺旋桨,那么平台就升得越高,故此题选B。

  59.D。本题考查动词。题干:从侧面移动平台需要__________ 给每一个螺旋桨提供不同的动力。从前一句可知越多的动力提供给螺旋桨,那么平台就升得越高,但是从侧面移动,则需要给每一个螺旋桨提供不同量的动力,从而使其能从侧面移动平台,故D(应用,使用)比较符合语境,所以D为正确答案。

  60.B。本题考查名词。题干:直升机现在正被用于一些__________ 中来帮助人们逃离着火的建筑物。根据语境,四个选项分别代入,直升机现在正被用于一些实例中比较符合语境,故B(案例,情况)为正确答案。

  61.A。本题考查副词。题干:__________ 救生筐不能达到大楼的每一层,__________ 筐子上的绳子变得不稳定了__________ 一定的长度。根据语境,前一句说的是从直升机抛出救生筐然后让人们爬进筐子从而逃生,本句说的是救生筐不能达到大楼的每一层,前后之间为转折关系,故A(不幸的是)为正确答案。

  62.B。本题考查连词。题干:不幸的是,救生筐不能达到大楼的每一层,__________ 筐子上的绳子变得不稳定了__________ 一定的长度。根据语境可知,空白处所在的句子是解释为什么救生筐不能达到大楼的每一层,正确答案应该为B。

  63.A。本题考查介词。题干:不幸的是,救生筐不能达到大楼的每一层,因为筐子上的绳子变得不稳定了__________ 一定的长度。四个选项分别代入,beyond the certain length(超过一定的长度)比较符合语境,因此A选项正确。

  64.B。本题考查动词。题干:到目前为止,Metreveli已经建造了小型的“鹰”来__________ 他的想法。根据语境,四个选项分别代入后,test his ides意为“检验他的想法”比较符合语境,因此答案为B。

  65.B。本题考查从句。题干:为了预防类似9•11事件,他已经获得足够的资金来建造一个大型的,四米见方的原型,并将其称之为“小飞鹰”。根据语境,是把所建造的原型称之为“小飞鹰”,这里选择which指代的是前文的prototype并且在从句中作宾语,故B为正确答案。

  2014年真题答案

  51.A。本题考查副词。题干:但是生态学家不可能__________ ,因此他们求助于普通公民的参与,这些公民有时被称为公民科学家。该段告诉我们,要在世界范围观察气候对大自然中生物的生命周期的影响,数量有限的科学家不可能足迹遍及天下,为此科学家求助于普通公民的参与。因此只能选择everywhere才能表示“遍及各地”。

  52.D。本题考查逻辑关系。题干:__________ 世界各地地方很多,又没有足够的科学家来观察,他们就会寻求你的帮助来__________ 世界范围内的气候征兆的变化。这个复合句中主句是“寻求帮助来记录气候变化”,造成需要寻求帮助的原因是“没有足够的科学家”,因此此处的逻辑关系应为因果,故本题选D。

  53.D。本题考查语义回现线索解题。题干:因为世界各地地方很多,又没有足够的科学家来观察,他们就会寻求你的帮助来__________ 世界范围内的气候征兆的变化。原因状语从句中讲到没有足够的科学家来“observe”,证明这个空格也需要填入observe:需要求助市民科学家来观察。故本题答案为D。

  54.D。本题考查语义呼应。题干:公民科学家参与科学观察的运动鼓励__________ 人来观察一个特定研究领域……公民科学家与professional scientists是对应的,因此他们只是普通人:0rdinary people。

  55.C。本题考查介词。题干:公民科学家参与科学观察的运动鼓励普通人来观察一个特定研究领域……并将这些数据送__________ 一个巨大的数据库,而这些数据是依靠他们自己的力量无法收集到的.。send…to是固定搭配,意思是“将……送到……”。

  56.A。本题考查语义呼应和固定搭配。题干:这能帮助小部分科学家追踪__________ 数据,而这些数据是依靠他们自己的力量无法收集到的。与small number ofscientists对应的应该是large amount ofdata,因此该空应该选large,其他选项都不是最佳答案。

  57.B。本题考查副词的用法。题干:__________ 就像公民记者帮助报道传统新闻报道方式所忽略的小型社区的相关信息一样,公民科学家也对他们所居住的环境很熟悉。四个选项中只有much能修饰like,表示相似的程度。very只能修饰形容词,副词或者动词,as则引导从句或者加名词,many修饰可数名词的复数形式。

  58.A。本题考查代词。题干:__________ 需要的就是每天或者每周留出几分钟来搜集数据并__________ 过来。这里that’s needed是空格处单词的定语从句,能与that搭配使用的不定代词充当先行词的,只有all。故本题答案为A。

  59.A。本题考查动词。题干:所需要的就是每天或者每周留出几分钟来搜集数据并__________ 过来。公民科学家所干的事情就是观察并记录,然后将搜集的数据给发送到数据库里,因此这里用send最合适。

  60.D。本题考查动词用法。题干:一群科学家和教育家在去年发起了一个__________ 纽约国家生物气候学的组织。“被称为”常常使用call,且常常放在名词后面充当后置定语。

  61.A。本题考查语义。题干:其中一个小组的首要尝试就是依靠科学家__________ 非科学家来收集关于每年植物开花和长叶子的数据。根据上文语义,科学家和非科学家都是很重要的渠道。因此选用alike。

  62.C。本题考查名词。题干:这一项目叫作花季追踪计划,它收集遍布美国的各种各样的植物生长周期的__________ 。本文几乎全文在讲公民科学家如何观察和搜集数据,因此用collect data是最合适的。

  63.C。本题考查形容词。题干:参与这一项目的人们——这一计划对所有人__________ —把他们的观察记录在花季追踪计划的网站上。很明显,本题的意思是“这一计划对所有人都开放”,将观察记录在追踪计划网站上便是开放的方式。因此本题选open最合适。

  64.D。本题考查动词。题干:人们没有__________ 成为专家——他们仅仅需要环视四周看看周围有什么。通过上下文可知,要做到公民科学家不需要成为植物学家(expert),只需要观察和记录。因此这里用have to(不得不)最合适,don’t have to的意思是“没有必要”。

  65.B。本题考查从句连词。题干:通过收集数据,我们就能够估算出气候变化对植物和生物群落会有__________ 的影响。这里想表达气候变化是如何影响植物和生物的,因此选用how是最合适的。

  2013年真题答案

  51.D。本题考查词汇。题干:秃鹰数量的急剧__________ 给生活在__________ 地区的人们带来破坏。从上下文语境来看,通篇文章都在叙述秃鹰濒临灭绝对印度环境的负面影响,而且文章的标题中的dying vultures也提供了线索。decline符合上下文的意思,意为“秃鹰的数量在急剧减少”。increase与上下文的意思相反。故D为正确答案。

  52.C。本题考查固定搭配。题干:秃鹰数量的急剧减少给生活在与鸟__________ 地区的人们带来破坏。从上下文语境来看,秃鹰数量的急剧减少不仅是这些鸟类的灾难,对当地居民同样也是如此,the same as意为“和……一样”,为固定搭配。故C为正确答案。

  53.C。本题考查介词。题干:这也给__________ 印度次大陆带来了公共健康的问题。从上下文语境来看,四个选项中只有across the Indian sub.continent(整个印度次大陆)符合题干,故C为正确答案。

  54.B。本题考查副词。题干:虽然它们的声誉和外观可能对许多印度人是不愉快的,但是__________秃鹰在维护印度城镇和乡村的方面扮演了非常重要的角色。从上下文语境来看,四个选项代入后,lon9意为“长期以来一直起作用”,合乎上下文的意思,故B是正确答案。

  55.B。本题考查词汇。题干:虽然秃鹰的名声不好,许多印度人也讨厌其长相,但是长久以来,秃鹰在维护全印度的城镇和乡村的__________ 方面扮演了非常重要的角色。四个选项分别代入后,B选项clean(清洁的)符合题干要求,其他选项dangerous意为“危险的”,smelly意为“有臭味的”,beautiful意为“漂亮的”,均不符合题干要求,故B是正确答案。

  56.D。本题考查词汇。题干:在印度,牛是神圣的动物,因而__________ 死后露尸户外,任其腐烂。露尸户外是印度的传统,所以此处填traditionally“传统地”。选项immediately意为“立即地”,occasionally意为“偶尔地”,hardly意为“几乎不”,都不通,因此D为正确选项。

  57.B。本题考查固定搭配。题干:秃鹰的消失__________ 以动物为生的野狗数量暴增。表达的是因果关系。“the disappearance ofthe vultures”是因,“an explosion in the numbers ofwild dogs feeding on the remains ofthese dead animals”是果,四个选项中只有lead to(导致)能表达这种因果关系,使题干很通顺。因此B为正确选项。

  58.A。本题考查词汇。题干:秃鹰的消失导致以__________ 动物为生的野狗数量暴增。从上下文语境来看,应该是死的动物,因此A为正确选项。

  59.D。本题考查状语从句。题干:这种可怕的疾病最终会影响当地的居民,__________ 野狗是狂犬病的主要携带者。前后是因果关系,四个选项中只有since(由于,因为)能表达这种因果关系。因此D为正确选项。

  60.B。本题考查词汇。题干:狂犬病也可能传播到其他生物,__________ 更大的问题。从上下文语境来看,前后为因果关系,所以B选项causing(导致)为正确答案。

  61.C。本题考查词汇。题干:采取行动的需求是__________ 。从上下文语境来看,空格后提到了“启动了应急项目”,可以推断要选的形容词是urgent(紧迫的),意为“采取行动已刻不容缓”,故C为正确选项。

  62.A。本题考查词汇。题干:科学家们正试图__________ 导致秃鹰死亡的疾病,如果可能的话,找到治愈该病的方法。四个选项分别代入后,identify(确定)比较符合语境,故A为正确选项。

  63.B。本题考查词汇。题干:在印度,人们注意到秃鹰的大批__________ 最早是在20世纪80年代。根据上下文语境,deaths可使全段的意思连贯,故B为正确选项。

  64.D。本题考查介词。题干:根据当时的物种调查显示,三种秃鹰的数量减少__________ 了90%以上。四个选项中只有by有“到(某事物)的程度”的意思。故C为正确选项。

  65.C。本题考查词汇。题干:由于大部分秃鹰每次只产一只蛋,幼鹰大约__________ 5年的时间才能成熟,因此,若想遏制住秃鹰数量的下降会是一项长期的、艰巨的任务。“花费或用多少时间”英语的常用的表达法是“take…days/months/years”,其他三个选项都不合适,故C为正确选项。
