Question

    Have you ever heard of spirit bears? They are endangered members of the black bear family. One in ten black bears is actually born with a spirit bear.

Clover, a three-year-old spirit bear, lives at B.C. Wildlife Park near Kamloops, British Columbias, Canada. He lost his parents two years ago and was raised at a wildlife center. When he was set free into the wild, he went into human camps looking for food. Wildlife experts tried to get him used to living on his own, but he continued to look for places where there were people. Finally the experts decided that he could not live in the wild. Since then, a total of $750000 has been collected to create a habitat for Clover.

The habitat covers about three acres(英亩) of land and includes natural forest, two ponds connected by a small river and something else. It will add a platform(站台) and a walkway later this year so that people can see Clover and his habitat more closely. There will also be a center where people can learn more about spirit bears. Besides, a black bear will be moved into the habitat so Clover will not feel lonely.

Spirit bears are also called Kermode bears after Francis Kermode, who first studied them. Kermode discovered that a small number of black bears carry a gene for the white fur. If a baby bear receive one of these genes from each parent, its fur will be a creamy white color.

There are about 1200 bears who carry the gene for white fur, but only about 200 white spirit bears in the world. Kermode bears are found only in British Columbia. They live in the Great Bear Rainforest, an area that covers the mainland and island along the coast of B.C. between Vancouver and Alaska.

1.According to the second paragraph, Clover ________

A.lost his parents when he was two B.could not find any food

【解析】

本篇介绍黑熊家族中濒临灭绝的成员百灵熊。它是少数黑熊携带白色皮毛的基因，如果一只小熊从父母那里得到其中一个基因，它的皮毛将是乳白色。文章介绍了从小失去父母的百灵熊Clover因为人类的抚养无法适应野生的环境，人们最后为它建了栖息地。

1.推理判断题。根据第二段Clove在一岁时失去父母，在野生动物中心长大，到3岁时，没法适应野生的环境，总要到人类的营地找吃的东西，可知它没办法自己找到吃的；故选B。

2.词义猜测题。由上文可知Clover因为人类的抚养无法适应野生的环境，根据第三段“The habitat covers about three acres(英亩) of land and includes natural forest, two ponds connected by a small river and something else.”—— 人们给它创造了包括天然森林，两个由一条小河连接的池塘和一些东西覆盖三英亩土地，供他生活的地方，由此推断habitat是指它的栖息地；故选B。

3.推理判断题。根据第三、四段“Kermode discovered that a small number of black bears carry a gene for the white fur. …only about 200 white spirit …bears in the world….Kermode bears are found only in British Columbia.”—— 可知Kermode bears是少数的黑熊携带白色毛的基因造成的，目前世界上只有大约200只，主要生存在British Columbia（加拿大的一个省）；可知百灵熊是珍稀动物，故选C。

4.篇章结构题。第一段介绍百灵熊是濒临灭绝的动物；第二、三段介绍在野生动物中心长大的百灵熊Clove无法适应野外的生存，人类为它建了一块栖息地；第四五段介绍了科学家Kermode对百灵熊的基因和生存环境的研究。故选D。
