  51.D。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。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。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。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,long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。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。因为秃鹰是以死牛为生。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。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。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,“all explosion in the numbers of wild 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。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。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。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。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。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。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。


  65.C。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。
