8 i% @! e2 d3 Z. c" C1.D短文的第一段告诉我们,人们通常认为动物园内的动物没有猎食的困难,也不受其他 猎食动物的威胁,所以一般寿命较长。但第一段并没有提及大象。第二段则说,动物园内的大象却不然,它们面临很多健康问题。所以,除了D以外,其他选项均不符合这两段内容。
* d, p8 s, R8 m. U: O- r1 ~2.B 第三段告诉我们,动物园,而不是这些研究人员,保存了所有园内动物的详细相关信息。所以应该选择8。其他三个选项均能在该段中找到相关内容。 1 g, \; D. I7 R/ P& j
3.C短文的第四段提供了答案。该段告诉我们,野生的雌性大象的平均寿命是动物园里的雌性大象平均寿命的3倍还多。 / G. B: n7 Q3 c' E7 s
4.D短文的第五段提供了答案。该段第三句的意思是:动物园里的大象不像野生大象那样活动,因此非常肥胖。他们也不像野生大象那样过着群居的生活,即live in herds and family groups。 5 g9 w. k, T% H$ i
5.A短文通篇陈述了大象在动物园内的生存问题,最后一段是全文的总结。该段第一句指出,对动物园大象的研究向人们提出了一个问题:是否应该将更多的大象关进动物园。该段还重复了第一、第二段的观点:其他动物在动物园能够很好地繁衍生息,而大象却不能。所以,A是正确选择。 B、C、D均没有在文中被提及。 |
