Hello, I'm a cute sloth(树懒). My family and I live in the forests of Central and South America. All of us have big eyes, small heads and very long arms like monkeys.
I can sleep for about 20 hours a day. When I'm awake(醒着的), I just stay in my tree. 17. But when I eat, I always eat a lot. I usually eat leaves and fruit. They taste so good!
People always think I'm lazy. Well, I don't like walking. 18. I can walk only about 1.8 to 2.4 metres a minute. About once a week, I go down from the tree. 19. It's easy to meet animals like lions and tigers under the tree. I'm afraid of them.
I don't like to take showers. There is always some green algae(藻)on my fur. 20. Other animals can't see me, so the algae can protect me.
I'm always friendly to people. Do you like me?
A. And I don't eat very often.
B. It makes me look like green leaves.

【分析】
本题为英语七选五题型，需结合上下文语境及逻辑关系选择最佳选项。解题思路：先通读全文，明确树懒的生活习性与语篇逻辑；再逐个分析空白处的前后句，梳理句子间的逻辑关联（递进、转折、因果等）；最后匹配对应选项。17空需衔接进食频率的描述，18空需承接走路的特点，19空需对应下树的危险，20空需解释绿藻的伪装作用。
【解析】
17. 空白前句提到树懒醒着时待在树上，后句转折说明吃东西时吃很多，A选项“而且我不经常吃东西”，衔接前后逻辑（不常吃→进食时量大），符合语境，故选A。
18. 空白前句说树懒不喜欢走路，后句讲其每分钟仅走很短距离，D选项“这对我来说太难了”，承接走路的困难属性，符合语境，故选D。
19. 空白前句提到树懒下树，后句说明树下有危险动物，E选项“那对我来说是最危险的时候”，衔接下树后的危险情况，符合语境，故选E。
20. 空白前句说树懒毛上有绿藻，后句讲其他动物看不见它，B选项“它让我看起来像绿叶”，解释绿藻的伪装效果，符合语境，故选B。
【答案】
17.A 18.D 19.E 20.B
