7.The Cuban iguana 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 t he over consuming of farm animals,housing development,and the building of tourist resorts on the beacheswhere 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.

分析 本文主要介紹古巴大蜥蜴的種族分類,生活習(xí)性和筑巢習(xí)慣等等.就目前情況看來,因為棲息地被破壞古巴大蜥蜴的種類在逐漸減少.
解答 32.C.猜測詞義題.根據(jù)95% of its diet consists of the leaves,flowers and fruits from as many as 30plant species,including the seaside rock bush and various grasses.可知古巴大蜥蜴的食物中95%都是葉子,花和水果等,說明它是食草動物.可猜出"herbivorous"意思是吃植物,故選C.
33.D.細節(jié)理解題.根據(jù)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).可知它把巢穴建在靠近仙人掌的地方是為了避免鱷魚的襲擊,故選D.
34.B.細節(jié)理解題.根據(jù)最后一個自然段根據(jù)第四段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the over consuming of farm animals,housing development和the building of tourist resorts on the beaches是造成棲息地破壞的原因,文中提到了三個原因,故選B.
35.A.寫作意圖題.本文介紹了古巴大蜥蜴的種族分類,習(xí)性和筑巢習(xí)慣等等,并說明因為種種原因它們的數(shù)量在減少.由此可見本文只是對古巴大蜥蜴的一個介紹,故選A.
點評 本文是一篇說明文,介紹了古巴大蜥蜴的種族分類,生活習(xí)性和筑巢習(xí)慣等等.要求學(xué)生根據(jù)文章所述事件的邏輯關(guān)系,對未說明的趨勢或結(jié)局作出合理的推斷;或根據(jù)作者所闡述的觀點理論,對文章未涉及的現(xiàn)象、事例給以解釋.考生首先要仔細閱讀短文,完整了解信息,準確把握作者觀點.
