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 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（圈養(yǎng)） and other conservation programs．

1.The underlined word "herbivorous" （Paragraph 2） probably means ．

A． dangerous B． gentle

【解析】

試題分析：本文主要介紹了古巴的一種大蜥蜴。它是西印度群島最大的巖石蜥蜴，也是一種最瀕危的蜥蜴種群，它由紅色的眼睛和一條粗粗的尾巴，是加勒比海地區(qū)最大的蜥蜴。它們分布在古巴大陸的南部沿海地區(qū)。這種蜥蜴是草食性，主要吃樹葉、花朵和水果，偶爾也會吃一些肉類。這種大蜥蜴由于人類圈養(yǎng)動物的過度消費，房屋建造，以及開發(fā)旅游地，導(dǎo)致它們的棲息地被破壞，因此數(shù)量在不斷減少。

1. of its diet consists of the leaves, flowers and fruits from as many as 30 plant species,意思是：古巴大蜥蜴飲食的95%主要來自于30多種植物物種的樹葉、花朵和水果，可知古巴大蜥蜴是一種食草性的動物。故選D。

2. avoid the attack from them, the Cuban iguana often makes its home within or near prickly-pear cacti （仙人掌）．意思是：為了防止來自他們（古巴鱷魚）的攻擊，古巴大蜥蜴在仙人掌里面或者附近筑巢。故選B。

3. 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．可知古巴大蜥蜴棲息地被破壞主要有農(nóng)場動物的過度消費、房屋開發(fā)、旅游勝地的開發(fā)三個原因。故選D。
