Question

    Scientists estimate that over 500 million species have died out throughout evolution. Here is a list of 4 incredible extinct animals.

Pinta Island Tortoise	The giant tortoise of Pinta lived on the island Pinta of the Galapagos Islands,Ecuador. By the end of the nineteenth century,most of the Pinta Island tortoises had been wiped out due to hunting. The last known individual was a male named Lonesome George who died on 24 June 2012. In his later years,he was considered the rarest animal in the world.
Falkland Islands Wolf	The Falkland Islands wolf was the only native land mammal of the Falkland Islands. The animal was hunted for his beautiful fur,and the shepherds(牧羊人），considering it a threat to the sheep,poisoned him. On the islands,there were no forests in which the species could take shelter,and its lack of fear towards man made it easy prey to kill. The last known individual died in the late 19th century on the western island.
Caucasian Wisent	The Caucasian wisent which went extinct in 1926 inhabited(栖息）the Caucasus mountains. In 1910 their numbers were estimated in the hundreds. When state authority collapsed after the First World War,the remaining population fell victim to hunters. The decline can also be contributed to an outbreak of foot-and-mouth disease that was introduced with cattle.
	The Javan tiger is an extinct subspecies of the tiger that was native to the Indonesian island of Java. Very little data was gathered about their behavior before they were driven to extinction. The reduction of its two main prey species,and the modification of its habitat led to the extinction of the subspecies in the 1980s.

① Pinta Island tortoise                ② Falkland Islands wolf

③ Caucasian wisent                  ④Javan tiger

A.②③①④ B.②③④①

C.③②④① D.③④②①

2.Which of the following is NOT the reason for extinction of the animals?

A.Pollution. B.Disease.

C.Hunting. D.Habitat loss.

3.Where does this article probably come from?

A.A travel brochure. B.A news report.

C.A nature magazine. D.A biology textbook.

3.C

【解析】

本文是一篇说明文。科学家估计，在整个进化过程中，超过5亿种物种已经灭绝。文章介绍了4种难以置信的灭绝动物。

1.

细节理解题。根据The last known individual was a male named Lonesome George who died on 24 June 2012.( 最后一个已知的个体是一位名叫龙瑟姆·乔治的雄性，于2012年6月24日去世)；The last known individual died in the late 19th century on the western island.( 已知的最后一只狼死于19世纪末的西岛。)；When state authority collapsed after the First World War,the remaining population fell victim to hunters.( 当第一次世界大战后国家权力崩溃时，剩余的成为猎人的受害者)；以及The reduction of its two main prey species, and the modification of its habitat led to the extinction of the subspecies in the 1980s.( 它的两个主要猎物物种的减少及其栖息地的改变导致了亚种在20世纪80年代的灭绝)可知，B项顺序正确。故选B。

2.

细节理解题。根据Pinta Island Tortoise部分的“due to hunting”； Falkland Islands Wolf部分的“The animal was hunted for his beautiful fur”（这动物因其漂亮的皮毛而被猎杀）；Caucasian Wisent部分的“The decline can also be contributed to an outbreak of foot-and-mouth disease that was introduced with cattle.(这种下降也可能是由牛引起的口蹄疫爆发所致) ”以及最后一段的the modification of its habitat led to the extinction of the subspecies in the 1980s.( 其栖息地的改变导致亚种在20世纪80年代灭绝。)可知，污染不是这些动物灭绝的原因。故选A。

3.

推理判断题。根据第一段的Here is a list of 4 incredible extinct animals.可知，文章主要介绍了4中难以相信的灭绝的动物，因此推断文章出自自然杂志。故选C。
