一、阅读短文，选择正确答案
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 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.
People can enjoy a day outdoors with the beauty of nature along the river. Wu and other villagers are happy to see the river looking good again.
