四、阅读理解
As we all know, too much trash is a big problem for our environment. A woman in Indonesia's Java island has come up with a great idea — lending books to children in exchange for trash.
Raden Roro Hendarti, nearly 50 years old, is a librarian in Muntang village. She started a "trash library", hoping to make children read more as well as make them realize the importance of environment protection. Each weekday, Raden puts all kinds of books on the back of her three-wheeler (三轮车) and rides to Muntang village. There, children line up to exchange plastic cups, bags and other trash for books from Raden's mobile library. After finishing the exchange, Raden carries back all the trash.
In the library where Raden works, there are thousands of books. Every time she shows up, children run to her "trash library". They all carry trash bags, and Raden's three-wheeler quickly fills with trash as the books fly out. Raden collects about 100 kg of trash each week. It is then sorted out and sent for recycling or sale. She is happy that children spend less time on online games because of the books.
Raden plans to take the mobile library service to neighboring areas as well. She says, "We all should take care of our trash in order to fight climate(气候) change and save the earth."
1.Which of the following shows how Raden's idea works
①She rides to Muntang village.
②She carries back all the trash.
③Children line up to exchange books for their trash.
④She puts books on her three-wheeler.
A.④ ① ③ ② B.④ ① ② ③

2.How much trash can Raden collect each weekday
A. About 100 kg. B. About 50 kg.
C. About 25 kg. D. About 20 kg.
3.What's Raden going to do next
A. To ask her neighbors for help.
B. To give the mobile library to her neighbors.
C. To exchange books for trash in more villages.
D. To tell children to spend less time on online games.
五、任务型阅读
On December 26th, 2020, China passed a new law to protect the Yangtze River, the "mother river" of China. It is Yangtze River Protection Law. It took effect(生效)on March 1st, 2021. It's the first law to protect a waterway in China.
The Yangtze River is almost 6,400 kilometers long and it is the longest river in Asia. It covers an area of about 1.8 million square kilometers, about one fifth of the national total. The Yangtze River provides one third of the country's freshwater resources(淡水资源), but it has met lots of environmental problems in recent years, such as heavy pollution and overfishing. Especially, the river's Chinese paddlefish(白鲟)has died out. So the "mother river" is in great need of protection. To solve these problems, China put a 10-year fishing ban(禁令)at the beginning of 2021.
The fishermen said they would give up fishing along the Yangtze River to protect the "mother river". A Chinese officer said that more support should be given to the fishermen to help them find new jobs and places to live.
Yangtze River Protection Law includes resource protection and green development. The government says the purpose of the new law is to strengthen environmental protection, use resources well and make the development sustainable(可持续的).
