(2020·山东省德州市武城五中高三月考)A living tortoise of its kind not seen in more than 110 years and feared to be extinct (灭绝的) has been found in a remote part of the Galapagos islands of Fernandina.
An adult female Fernandina tortoise was spotted Sunday by a joint team of the Galapagos National Park and the USbased Galapagos Conservancy. Researchers think there may be more members of the tortoise on the island because of the droppings and tracks they found. The team took the tortoise, likely more than 110 years old, to a breeding (繁殖) center for rare tortoises where it will stay in a specially designed fence.
The only other living member of the tortoise was found in 1906. Since then, researchers have come across tortoise tracks and bite marks on plants, and there was a possible unconfirmed sighting in 2009. But Sunday's discovery was the first confirmed sighting and together with the possibility, of finding more members of this kind has raised the possibility of breeding.
Fernandina is the third largest Galapagos island and is famous for the La Cumbre volcano, one of the most active in the world. The island lies in the Pacific Ocean about 1,000 kilometers off Ecuador's mainland. In listing the Fernandina tortoise as possibly extinct, the conservation group said on its website that this kind of tortoise may have submitted to “the frequent volcanic lava (岩浆) flows that nearly cover the island.”
The Galapagos islands host unique wildlife whose characteristics helped Charles Darwin develop his theory of evolution. It was declared a UNESCO World Heritage site in 1979.
篇章导读：本文是一篇说明文。文章讲述了在菲尔南迪娜岛上发现销声匿迹了110多年、人们担心其灭绝的活体乌龟。这一新的发现大大增加了这种珍稀乌龟繁殖的几率。
1．How many Fernandina tortoises are sure to be living according to the passage?
A．One. B．Two.
C．Three. D．One thousand.
答案：B 细节理解题。根据第三段第一句中“The only other living member”可知，现在已知存活的菲尔南迪娜乌龟只有两只。
2．What is important about the new discovery of the living Fernandina tortoise?
A．Improving the chance for breeding.
B．Confirming the theory of evolution.
C．Showing its adaptation to volcanic lava.
D．Finding more living members of its kind.
答案：A 细节理解题。根据第三段最后一句中“has raised the possibility of breeding”可知，发现菲尔南迪娜乌龟活体增加了繁育的可能性。
3．Which of the following caused the Fernandina tortoise to die out?
A．Living on the remote islands.
B．Hunting of the human beings.
C．Living in the bad environment.
D．Staying in specially designed fences.
答案：C 推理判断题。根据第四段特别是最后一句可知，菲尔南迪娜乌龟生存的海岛上有活火山，岩浆差不多覆盖了整个海岛，乌龟已经屈从于这样的环境。由此判断，恶劣的生存环境导致了过去一百多年菲尔南迪娜乌龟的消亡。
4．What can be a suitable title for the Text?
A．Proper Place to Host Unique Wildlife
B．Evidence to Prove Survival of the Fittest
C．Rare Tortoise Found on Fernandina Island
D．Possibility of Breeding Fernandina Tortoise
答案：C 标题判断题。本文主要介绍了一项新的发现，即在菲尔南迪娜岛上发现销声匿迹了110多年、人们担心灭绝的活体乌龟。C项“菲尔南迪娜岛上发现了珍稀乌龟”符合题意。
【词汇积累】 ①spot v. 注意到；发现 ②conservation n. (对环境的)保护 ③come across 偶遇；无意中发现 ④ submit to 屈服；使……受到
