A tropical rain forest is a warm, rainy place. Many trees and plants grow there. Hidden in the thick forest are amazing animals. Here are just a few of them.
Toucans are birds with huge beaks(鸟嘴). They live in the leafy tops of trees. They eat mostly fruit. Why is a toucan’s beak so large? Scientists say it helps the bird lower its body temperature when it’s too hot.
Green iguanas are reptiles. A reptile is an animal that has hard, dry skin. Green iguanas are large, usually between 4 and 6 feet long and weigh about 11 pounds. Their sharp claws(爪子) help them climb trees. They eat leaves, flowers, and fruit.
Jaguars are wild cats. They spend most of their time in small trees and on the forest floor. They are top predators in the rain forest. A predator is an animal that eats other animals for food. Jaguars hunt for food mostly at night. They are good swimmers. Sometimes they catch fish to eat.
Sloths live in tree branches. They are very slow and they don’t move much. They hang upside down using their long claws. To save energy, sloths sleep 15 to 18 hours a day. They look for food the rest of the time. They eat leaves and fruit.

解析
【分析】
本题为阅读理解题，需根据题干问题回到原文定位对应信息，逐一分析选项选出正确答案。第16题需归纳四种动物的共同特征，第17题需判断选项与原文信息是否一致，第18题需根据文章内容判断其所属的杂志板块。
【解析】
16. 分别定位四种动物的生活地点：巨嘴鸟生活在树的叶顶，绿鬣蜥爬树，美洲虎大部分时间在小树上，树懒生活在树枝上，可知它们都在树上活动，对应选项B。A选项中美洲虎以其他动物为食，并非都吃树叶和水果；C选项树懒行动缓慢，并非都移动快；D选项热带雨林温暖多雨，并非都喜欢炎热干燥，故排除A、C、D，选B。
17. 逐一比对选项与原文：A选项巨嘴鸟的大喙帮助降温，而非爬树，错误；B选项绿鬣蜥的硬皮肤用于爬树，而非降温，错误；C选项原文明确提到美洲虎主要在夜间捕猎，正确；D选项树懒每天睡15-18小时，其余时间找食物，并非大部分时间找食物，错误，故选C。
18. 文章介绍热带雨林的动物，属于自然科学范畴，最可能出自杂志的“自然”板块，故选D。
