Welcome to the Amazon rainforest. As the largest rainforest in the world, it plays an important role in keeping
the balanced ecosystem on the Earth. With an area of around 6 million square kilometers, the Amazon rainforest is
more than half the size of China. This area has a great many species (物种). Actually, one in ten known species in the
world can be found here.
Of the 390,000 plant species known to us, more than 40,000 can be found in the Amazon. There are different
levels (层) in the forest. At the bottom (底部) is a system of roots under the ground. Above that is leaf litter on the
dark forest floor. The next level is made up of shorter plants with large leaves. Then there are the towering (高耸的)
ancient hardwoods, and finally the tops of the trees which are taller than any other level of trees in the forest. Each
level of the forest forms its own little world, home to different kinds of living things.
The Amazon rainforest is a treasure house of species that can be used for food or medicine. What’s more, the
Amazon rainforest breathes life into the planet by producing over 20 percent of all the Earth’s oxygen (O₂). So it is

The Hutuo River is the mother river of Shijiazhuang, the capital city of Hebei Province. About 20 years ago,
it was dirty and almost dried up. Thanks to the government’s (政府的) work, it becomes clean now.
Wu Wenzhong, a 58-year-old villager, lives near the river. “My friends and I often played with water, swam
and caught fish in it when I was a child. I liked catching fish best,” he said. He remembers that the villagers must
cross the river by boat at that time. But later, it got dirty and started to dry up.
To remediate (修复) the river, the government do a lot of things. They clean the river up and build levees (防
洪堤). They plant trees, grass and flowers. They set up fences (防护栏) and stick “No Swimming” signs along the
river to protect people. They ask people not to put dirty water into the river. They also have a long-term plan to protect
the river.
Now, there are more than 20 kinds of birds living around the river. It becomes a home for birds again.
