Question

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 mainly 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 eat animal matter, and individuals have been watched 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 living throughout the rocky southern coastal areas of mainland Cuba and its surrounding islands with a wild population growing rapidly 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 decreasing, more quickly on the mainland than on the outlying islands. One of the reasons for their decrease is habitat destruction caused by the over consuming of farm animals, housing development, and the building of tourist resorts(度假胜地) on the beaches where the animals prefer to build their nests. Although the wild population is decreasing, the numbers of iguanas have been sharply increased as a result of captive-breeding(圈养)and other protection programs．

【解析】

试题分析:本文是一篇说明文。介绍了大蜥蜴的基本情况。它生活在整个古巴南部岩石海岸地区，是濒危品种，喜欢吃植物，但是也吃肉食。由于建农场、建住房、建旅游胜地，导致了栖息地的减少，野生大蜥蜴面临灭种的威胁，但是因为圈养和其他保护措施的施行，蜥蜴的数量大大增加了。

1.D 细节理解题。由第二段第一句95% of its diet consists of the leaves, flowers and fruits from as many as 30 plant species,知他们食物的95%是叶子、花和水果，有30多品种。故可以推断出该词为吃植物的。故选D。

2.D 细节理解题。由最后一段的第二句their decrease is habitat destruction caused by the over consuming of farm animals, housing development, and the building of tourist resorts(度假胜地) on the beaches知有三个原因导致了栖息地减少：过度消耗农场动物、建房子、建度假胜地。故选D。
