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

2.Why does the Cuban iguana build its nest near prickly-pear cacti?

A． To keep itself cool．

B． To avoid crocodiles' attack．

C． To stay away from people．

3.How many reasons are mentioned for the habitat destruction?

A． Two． B．Five． C. Four． D． Three．

4.What's the author's purpose of writing the text?

A． To give us a brief introduction to the Cuban iguana．

B． To show he is concerned about the Cuban iguana．

【解析】

試題分析: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。

1. 詞義猜測題。根據(jù)后文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。故選D.

2. 細(xì)節(jié)題。根據(jù)第三段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 可知，為了避免古巴鱷魚Cuban crocodiles的攻擊，the Cuban iguana經(jīng)常把巢穴建在仙人掌旁邊。故選B.

3. 細(xì)節(jié)題。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，共三個。故選D.

4. 作者意圖題。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.
