Question

【題目】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 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.

Answer 1

【答案】

【1】C

【2】D

【3】B

【4】A

【解析】

試題分析：文章主要向讀者介紹了古巴藍鬣蜥，包括它的外形、生活習性、分布、現(xiàn)存狀況等。藍鬣蜥是西印度巖鬣蜥蜴中體型最大的一種。

【1】C猜測詞意題。根據(jù)“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，Cuban iguana(藍鬣蜥)是食草動物，其95%的食物都來自30多種植物的葉子、花蕊、果實等。故選C。

【2】D細節(jié)理解題。根據(jù)第三段“by Cuban crocodiles. To avoid the attack from them, the Cuban iguana often makes its home within or near prickly-pear cacti”可知，藍鬣蜥在在仙人掌里或仙人掌附件筑巢是為了避開鱷魚的襲擊，故選D。

【3】B細節(jié)理解題。根據(jù)最后一段“caused by the over consuming of farm animals, housing development, and the building of tourist resorts on the beaches”可知，導致棲息地遭到破壞的原因有三個，故選B。

【4】A根據(jù)第一段“The Cuban iguana is a species of lizard（蜥蜴） of the iguana family. It is the largest of...This species with red eyes...”第二段“The Cuban iguana is primarily herbivorous;”和第三段“The Cuban iguana is distributed throughout the rocky...”及最后一段“In general the species is in decline...”可知，文章主要介紹了古巴藍鬣蜥的情況，包括它的外形、生活習性、分布、現(xiàn)存狀況等，作者只是提到藍鬣蜥的數(shù)量在下降，而未提到其正在瀕臨滅絕，故選A。
