They cover only about 6% of the world's land, but are home to more than half of all living things. These dense forests are full of life, from tiny insects to large animals, and from small plants to tall trees. The rainforest has different layers. The top layer is called the emergent layer, where the tallest trees reach up to 70 meters. Below that is the canopy, a thick layer of leaves and branches that stops most sunlight from reaching the layers below. Next is the understory, with smaller trees and bushes. The bottom layer is the forest floor, where only a little sunlight gets through. Many rainforest animals have special skills to live in their layers. For example, sloths hang from the canopy branches. Their long claws help them stay there, and their slow movement helps them save energy. Toucans have big beaks to reach fruit on thin branches that can't hold their weight. On the forest floor, jaguars use their spots to hide in the shadows while hunting. Rainforests are important for the whole world. They take in carbon dioxide（二氧化碳） and give out oxygen（氧气）, which helps keep the air clean. They also help control the world's weather. But rainforests are in danger. Every year, large areas are cut down for wood or to make space for farms. This destroys the homes of many animals and plants, and may even change the world's climate. （ ）1.(细节理解题) What percentage of the world's land do rainforests cover? A.About 6% B. About 16% C. About 26% D. About 36% （ ）2.(词义推测题) What does the word "dense" mean in the first paragraph? A. Dry B. Thick with plants C. Cold D. Easy to walk through （ ）3.(推理判断题) Why do toucans have big beaks? A. To hang from branches B. To hide from predators C. To reach fruit on thin branches D. To run fast on the forest floor （ ）4.(排序题) Put the layers of the rainforest from top to bottom. ① understory ② emergent layer ③ forest floor ④ canopy A. ②→④→①→③ B. ④→②→①→③ C. ②→①→④→③ D. ④→①→②→③ （ ）5.(主旨大意题) What is the main idea of the passage? A. How animals live in the rainforest B. The layers of the rainforest C. Why rainforests are amazing and important D.
