试题详情及答案解析

The Cuban iguana(大蜥蜴) is a species of lizard（蜥蜴） of the iguana family． It is the largest of the West Indian rock iguanas, one of the most endangered groups of lizards． This species with red eyes and a thick tail is one of the largest lizards in the Caribbean．
The Cuban iguana is primarily herbivorous; 95% of its diet consists of the leaves, flowers and fruits from as many as 30 plant species, including the seaside rock bush and various grasses． However, Cuban iguanas occasionally consume animal matter, and individuals have been observed eating the dead flesh of birds, fish and crabs, The researchers wrote that quite a few people on Isla Magueyes could have caused this incident．
The Cuban iguana is distributed throughout the rocky southern coastal areas of mainland Cuba and its surrounding islands with a wild population booming on Isla Magueyes, Puerto Rico． It is also found on the Cayman Islands of Little Cayman and Cayman Brac, where a separate subspecies occurs． Females guard their nest sites and often nest in sites half destroyed by Cuban crocodiles． To avoid the attack from them, the Cuban iguana often makes its home within or near prickly-pear cacti （仙人掌）．
In general the species is in decline, more quickly on the mainland than on the outlying islands． One of the reasons for their decline is habitat destruction caused by the over consuming of farm animals, housing development, and the building of tourist resorts on the beaches where the animals prefer to build their nests． Although the wild population is in decline, the numbers of iguanas have been sharply increased as a result of captive-breeding（圈养） and other conservation programs．

试题分析：本文主要介绍了古巴的一种大蜥蜴。它是西印度群岛最大的岩石蜥蜴，也是一种最濒危的蜥蜴种群，它由红色的眼睛和一条粗粗的尾巴，是加勒比海地区最大的蜥蜴。它们分布在古巴大陆的南部沿海地区。这种蜥蜴是草食性，主要吃树叶、花朵和水果，偶尔也会吃一些肉类。这种大蜥蜴由于人类圈养动物的过度消费，房屋建造，以及开发旅游地，导致它们的栖息地被破坏，因此数量在不断减少。
【小题1】细节题。由第二自然段95% of its diet consists of the leaves, flowers and fruits from as many as 30 plant species,意思是：古巴大蜥蜴饮食的95%主要来自于30多种植物物种的树叶、花朵和水果，可知古巴大蜥蜴是一种食草性的动物。故选D。
【小题2】细节题。由第三自然段最后一句To avoid the attack from them, the Cuban iguana often makes its home within or near prickly-pear cacti （仙人掌）．意思是：为了防止来自他们（古巴鳄鱼）的攻击，古巴大蜥蜴在仙人掌里面或者附近筑巢。故选B。
【小题3】细节题。由第四自然段One of the reasons for their decline is habitat destruction caused by the over consuming of farm animals, housing development, and the building of tourist resorts on the beaches where the animals prefer to build their nests．可知古巴大蜥蜴栖息地被破坏主要有农场动物的过度消费、房屋开发、旅游胜地的开发三个原因。故选D。
【小题4】主旨判断题。文章主要介绍了古巴大蜥蜴的生活习性、分布地区，以及目前由于人类活动栖息地被破坏，濒临灭绝的现状。因此，作者写这篇文章的目的主要是为了向人们介绍古巴大蜥蜴这种动物。故选A。
