A sloth(树懒) walks slowly, but we like it very much. Sloths live in the forests of South and Central America. They move so slowly that algae (海藻)grow on their bodies. They give sloths a green colour that helps them to hide from predators(捕食者)in the trees.
This green is a lucky “colour” for sloths. That’s because most of them are too slow to run away from predators. And they are even slower on the ground than they are in the trees. Some walk only 4 meters every minute on the ground.
Why do sloths move so slowly? It has a lot to do with their food. Sloths may all look the same to us. But in fact, there are two main kinds of sloths. One has two toes (脚趾) while the other has three toes. The two-toed sloths eat both plants and animals. And the three-toed sloths eat mainly tree leaves and flower buds.
Leaves and buds provide very little energy. Sloths save energy by not moving very often. They sleep and rest a lot. Some even sleep up to 20 hours a day!
There are very few sloths now. We must protect them. Nobody can hunt them in South and Central America.

本题为英语阅读理解的判断正误题，解题思路为：1. 通读短文，掌握短文关于树懒的生活区域、外形特征、移动特点、种类、食物及保护现状等核心信息；2. 针对每道小题，定位原文中对应表述的句子；3. 对比选项与原文的细节，判断选项表述是否与原文一致，若一致则为正(T)，不一致则为误(F)。
【解析】
71题：原文第一段第二句明确说明树懒生活在“South and Central America（南美和中美）”，而选项中是“North and Central America（北美和中美）”，地域描述错误；且原文第一段第一句提到树懒“walks slowly（移动缓慢）”，选项中“move quickly（移动迅速）”与原文不符，故判断为F。
72题：原文第一段第四句指出海藻给树懒的是“green colour（绿色）”，帮助它们隐藏，选项中“yellow colour（黄色）”与原文颜色描述不符，故判断为F。
73题：原文第二段第二句提到树懒在地面比树上更慢，“Some walk only 4 meters every minute on the ground（有些在地面每分钟仅走4米）”，与选项表述完全一致，故判断为T。
74题：原文第三段第二句说明树懒“two main kinds（两种主要类型）”，选项中“three main kinds（三种主要类型）”与原文种类数量不符，故判断为F。
75题：原文最后一段提到“very few sloths now. We must protect them（现在树懒数量极少，我们必须保护它们）”，与选项表述一致，故判断为T。
