Question

“A rolling stone gathers no moss (苔藓),” but there is one living animal that does gather moss — the three-toed sloth（树懒） of South America. This slowest-moving member of the animal kingdom is so inactive that moss actually gathers on its body and turns it green — strange as it seems!

Most of the sloth’s life is spent motionless, hanging upside down from a limb（大树枝）.  And that is the way its hair grows. Long and coarse, the strands from receptacles for the damp jungle algae（藻类）turn the brown fur a mossy green. Actually this moss helps the animal survive because it serves as a perfect camouflage against the leafy trees and hides the sloth from the jungle’s swift-moving hunters. The sloth would have little chance of survival on the ground. With long, curved claws hooded over the limb of a leafy tree, it spends the long hot hours during the day drowsing and eating. Inch by inch, it strips the leafy limbs bare and crawls slowly down the trunk to find a new dining spot, but only at night.

In addition to looking rather like a vegetable, the sloth is a strict vegetarian.  Running out of its favorite leaf is about the only thing that will make a sloth move. Then its appetite（食欲）may even force the animal into swimming a stream to reach a succulent（肉质植物）. It will also force it into fighting to keep the tree all to itself. The sloth is lazy and prefers to be alone, but it will tolerate its own relatives!

【解析】

试题分析：本文介绍了懒惰的动物---三趾树懒。

1. 主旨大意题。根据文章第一段“A rolling stone gathers no moss (苔藓),” but there is one living animal that does gather moss — the three-toed sloth（树懒） of South America.（滚动的石头不长苔藓但是有一种活的动物聚集苔藓——三趾树懒。）This slowest-moving member of the animal kingdom is so inactive that moss actually gathers on its body and turns it green — strange as it seems!（这个动物王国中行动最缓慢的成员是如此不活跃以至于苔藓实际上聚集在它的身体上，把它变成绿色，看起来很奇怪！）可知，本文在介绍一种懒惰的动物，故选D。

2. 推理判断题。纵观全文，可知作者在向普通读者介绍一种特殊的动物，故选C。

3. 细节理解题。根据第二段第一句Most of the sloth’s life is spent motionless, hanging upside down from a limb（大树枝）.可知，大部分树懒的生活是静止不动的，从树上倒吊着。故B是错误的，故选B。

4. 推理判断题。根据最后一段第二句Running out of its favorite leaf is about the only thing that will make a sloth move.可知，吃完最喜欢的树叶后，树懒会移动找食物。故选C。

5. 推理判断题。根据第一段中the three-toed sloth（树懒） of South America可排除A；根据第二段第二句Long and coarse, the strands from receptacles for the damp jungle algae（藻类）turn the brown fur a mossy green.可知排除B；根据第二段最后一句it strips the leafy limbs bare and crawls slowly down the trunk o find a new dining spot, but only at night.可知排除C。纵观全文，D项The sloth will never fight with other animals.（树懒不与其他动物打架。）文中未提到，故选D。
