Rainforests are some of the most amazing places on earth. They are full of life, with thousands of different plant and animal species. These thick forests are found in warm and wet areas near the equator.
The rainforest is like a huge, green world. The tall trees form a canopy天篷, which is like a big roof high above the ground. Under this canopy, there are many smaller plants, vines and flowers. The air is always humid, filled with the sounds of birds, insects and animals.
Rainforests are very important for our planet. They are often called the "lungs of the earth" because they absorb a large amount of carbon dioxide and release oxygen. This helps to keep the air clean and healthy for us to breathe.
Many animals live in the rainforest. Monkeys swing from tree to tree, colourful birds fly among the branches, and strange insects crawl on the leaves. There are also big cats like jaguars, which are excellent hunters.
However, rainforests are in danger. People are cutting down trees for wood, farming and building. This is destroying the homes of many animals and plants. We need to protect the rainforests to keep our planet healthy.

解析
【分析】
这是一篇科普类的细节型阅读理解，所有题目的正确答案都可以在原文中直接找到对应表述，解题时首先可以先浏览每道题干，划出核心疑问关键词，之后带着关键词回到原文对应段落定位相关语句，将语句内容和各个选项逐一比对，排除不符合原文的错误选项，就能快速选出正确答案，不需要额外做复杂的引申推理。
【解析】
1. 定位原文第一段最后一句"These thick forests are found in warm and wet areas near the equator."，可知雨林分布在赤道附近温暖潮湿的区域，对应B选项，A寒冷干燥区域、C山区、D沙漠均不符合原文描述，因此选B。
2. 定位原文第二段第二句"The tall trees form a canopy, which is like a big roof high above the ground."，可知雨林里的天篷是高大树木形成的、类似大屋顶的结构，对应D选项，A一种植物、B一类云、C一群动物均不符合原文描述，因此选D。
3. 定位原文第三段第二句"They are often called the "lungs of the earth" because they absorb a large amount of carbon dioxide and release oxygen."，可知雨林被称为地球之肺的原因是它吸收大量二氧化碳、释放氧气，对应B选项，其余选项的表述均未在原文中提及，因此选B。
4. 定位原文最后一段前两句"However, rainforests are in danger. People are cutting down trees for wood, farming and building."，可知雨林面临的主要威胁是人类为获取木材、开垦农田和建设房屋砍伐树木，对应C选项，A动物过多、B洪水等自然灾害、D缺少阳光均不是原文提到的主要威胁，因此选C。
