23、sh, offering rich food sources for birds.可知，鸟儿是以水草和鱼儿为食的， 故选B。3.推理判断题。根据文章第二段中的Each March and April, when ice and snow covering the Qinghai-Tibet Plateau starts to melt，可知每年的三四月份，雪融化了， 春天来了，故答案D是正确的。4.细节理解题。根据文章的第四段可知政府给人们普及动物保护法，而且告诉人们保护动物的知识，并呼吁人们爱护鸟儿， ABC选项均为正确的，故选D。四.答案：1.D; 2.B; 3.C; 4.A; 5.C;

25、ence可以推知,野生动物正在遭受巨大威胁,每天都有一些物种灭绝,即:消失。D选项正确。2.前文提到每天都有物种消失,那么该句应指科学家们正在竭尽全力保护这些物种,使它们免于灭绝。故B选项正确。3.上文最后一句提到科学家们竭尽全力保护濒临灭绝的物种,由此推知,该处应指Chris和Tim帮助濒危物种繁殖,增加它们的数量,这样它们才不至于灭绝。故该空应指繁殖,C选项正确。4.自从2004年,Emma一直由Chris和Tim照顾。该空和下一句中的human caretaker呼应。故选A。5.根据空后的human caretakers可知,caretaker当然是照看Emma的。故该句应指:出生在一

26、个国际鹤基地,Emma由人类抚养照看。故选C。6.根据空后的though(尽管)可知,though前后的两个句子之间是转折关系。后面提到,她过得很开心。根据转折关系,那么前文应该表示但是这导致了出乎意料的结果。B选项正确。7.根据下文中的become deeply attached to humanseven killing some of them等内容可知,因为Emma一直由人类照看,所以它没有将自己看作是一只鹤,而是深深的依恋上了人类。故选A。8.根据上文,Emma不把自己当作鹤,所以它拒绝和雄鹤生活在一起。B选项正确。9.根据even(甚至)这个递进关系可知,Emma不仅拒绝和雄鹤生活

27、在一起,而且因为弄死了几只雄鹤而臭名昭著。故D选项正确。10.Emma拒绝和雄鹤生活,这当然使得她不可能生育小鹤,成为妈妈。D选项正确。11.上文提到Emma拒绝和雄鹤生活,使得她不可能生育小鹤。下文提到两位动物园管理员不想看到这一物种的灭绝。由此推知,上下文之间是转折关系。C选项正确。12.经过努力,Chris和Tim成功的将人工繁殖和自然繁殖结合在一起。A选项正确。13.Chris和Tim成功的将人工繁殖和自然繁殖结合在一起,这使得Emma诞育了五只幼鹤。enable sb. to do sth.意为使能够做某事,D选项正确。14.根据后文的 more efforts must be ma

28、de可以推知,尽管两个人为自己的成就感到骄傲,但是他们还需要付出更多努力,因为野生鹤的数量在减少。所以他们还不能完全放心(白鹤不会灭绝)。故选C。assured意为确定的,有把握的,自信的。15.根据because可知,前后句之间是因果关系,根据more efforts must be made可以推知,野生白鹤数量在减少,所以,还要付出更多的努力(来挽救白鹤灭绝)。故D选项正确。16.前文提到:野生白鹤数量正在减少,很多其他物种似乎也在逐渐灭绝。该句提到,并不是所有的人都意识到野生动物有思想,感情,以及平等生存的权利。很明显,该句是对前文出现野生动物濒临灭绝原因的一种解释。故B选项正确。af

29、ter all:毕竟(用于解释和说明理由)。17.针对上文提到的很多物种灭绝这种现象,作者提出一个问题:我们如何来消除将人类和动物隔开的不断扩大的鸿沟呢?B选项正确。18.前文提出一个问题:我们如何来消除将人类和动物隔开的不断扩大的鸿沟呢?Chris和Tim的做法给我们提供了一个答案。C选项正确。19.根据下文中的hold all the solutions可以推断出,人类认为自己的大脑掌握着所有的解决办法。即:人类认为自己的大脑可以想出所有的解决办法。A选项正确。20.根据转折词but可以推知,人类想当然的认为自己的大脑掌握着所有的解决办法。但或许他们可以用心更好地引领他们去保护这些濒危的动物。故A选项正确。
