Many years ago，there were lots of trees on earth，because summer lasted a whole year．What was the forest like? It is not difficult to see，because parts of that ancient（古老的）forest still stand．It is the rainforest．Here，even in a sunny day water drops through the leaves．

Today's largest rainforest is in South America．It covers about a million square miles．All the trees are very tall；the young trees are nearly sixty feet high．But it is not easy for some to grow higher because very little sunlight leaches them．

Many trees are about 60 to 120 feet high．Some are even taller．The tallest trees can be 200 feet high．

In this forest of tall trees，plant life is rich，animal life is rich，too．At different heights live different animals and many different noises can let you know where they are．

1. Where are the rainforests?
Rainforests cover six per cent of the Earth’s surface. There are rainforests in many parts of the world but the biggest forests are in South America, Africa and South East Asia. There aren’t any rainforests in Europe or North America.
2. What’s in the rainforests?
About 75% of all the types of animals that we know come from rainforests. Thousands and thousands of animals live in rainforests. There are many very beautiful birds, insects and  reptiles. Many of them live in the trees, more than 30 metres from the ground. There are also thousands of different plants—and lots of tall trees! It is always hot in a rainforest and
the ground is always wet. It is also dark.
3. Why are the rainforests important?
The rainforests are very important for us. We need them! The trees and other plants in the forest help to make the air that we breathe. They give us wood, rubber, fruits and many of our medicines.
4.    
Unfortunately, in many places, the rainforests are in danger. For example, many years ago there was a large rainforest in Java. There were thousands of different plants and animals in the forest, but now there is nothing. People chopped down the trees because they wanted to grow rice. Many animals lived in the rainforest. Some of them went to other parts of Java but many of them disappeared — forever. The same thing is happening now in many other parts of the world. The rainforests are in danger.
