A
Forests are home to many wild animals. The population explosion and more human activities in the forests have caused many of their native species(物種)to become endangered.
Giant Panda
The giant panda, one of the most recognizable endangered species, is a large, docile species of bear native to the forest of eastern China, Myanmar and Vietnam. Because of its limited diet- the panda’s main source of food is bamboo- the species is limited in its habitat to areas where bamboo is available. Now the species only can be found today in 20 small patches of forest at the western edge of its historic range.
Gray and Red Wolves
The gray wolf, which once ranged from the East Coast of America to the West, and south to Mexico, now has a population of only 5, 000 in the lower 48 states, mostly in the Rocky Mountains. The red wolf, native to the southeastern United States, was declared extinct(已滅絕的) in the wild in 1980.
Red-Crowned Crane
The red-crowned crane is native to Japan, Korea and eastern China. Agricultural expansion and deforestation (森林砍伐) in these areas have removed a great deal of the marshes and forests that are the crane’ s primary habitats. For a time, the crane was thought to have completely disappeared from Japan, but the recent discovery of cranes in Japanese marshlands has restarted conservation efforts. Today, around 2, 500 cranes live in the wild, including 1,000 in Japan.

【答案】1. D 2. B 3. C
【解析】
本文是說明文。本文介紹了大熊貓、灰狼和紅狼、丹頂鶴等瀕臨滅絕的野生動物。
【1題詳解】
細節(jié)理解題。根據(jù)第一段的“The population explosion and more human activities in the forests have caused many of their native species(物種)to become endangered.( 人口膨脹和森林中更多的人類活動已經(jīng)導致許多本地物種瀕臨滅絕。)”可知，人類活動導致野生動物成為瀕危的。故D項正確。
【2題詳解】
細節(jié)理解題。根據(jù)第三段中的“The red wolf, native to the southeastern United States, was declared extinct(已滅絕的) in the wild in 1980.”可知，紅狼原產(chǎn)于美國東南部，是北美的本土動物，故B項正確。
【3題詳解】
推理判斷題。根據(jù)第一段中的“The population explosion and more human activities in the forests have caused many of their native species(物種)to become endangered.”可知，人口膨脹和森林中更多的人類活動已經(jīng)導致許多本地物種瀕臨滅絕,以及下文就介紹了大熊貓、灰狼和紅狼、丹頂鶴等幾種瀕臨滅絕的野生動物,由此可知本文的目的是介紹一些瀕臨滅絕的物種。故C項正確。
