On Earth Day, we remember nature and learn ways to protect our environment. You can do lots of good things for the earth. Here are some ideas to keep in mind. *Recycle cans, bottles, and paper. Save them at home and at school, and help your family recycle them. *Ride your bike or walk to school to keep the air clean. *Use both sides of your paper at school and at home. *Turn off the TV when you've finished watching it. *Don't leave the water running while you brush your teeth. *Turn off the lights when you leave the room. And remember: Don't ever think you're not important to our earth. You are! B. World Environment Day June 5 is World Environment Day. This makes us pay more attention to our environment and we need to protect it. When Wang Boxuan, a Beijing high schoolboy, uses up his exercise books, he does not throw them away. Each one is stored at his school with hundreds of exercise books given by other students. Then they are sold to a Beijing paper making factory. The paper is recycled and used again by students and teachers in the school. At the same time, the money made from the sales goes towards schools in Inner Mongolia for planting trees and grass. This place is one of the sources of the sandstorms that often attack Beijing during springtime. Wang's school is one of the schools in the capital that take part in the"green promise"environment protection activity. So far, nearly 210,000 students have taken part in the activity, collecting more than 87 tons of waste paper. With the Olympic Games coming to Beijing in 2008, students are eager (渴望) to help make the capital a more pleasant place. "There are some environment problems in the city, such as sandstorms." said Wang. "We should do our duty and encourage others to do so as well." Vice- Premier (副总理) Zeng Peiyan has written a letter to the teachers and students to encourage them to go on supporting environment protection. 本文来源：https://www.wddqw.com/doc/099f9b4b0b4e767f5bcfce35.html
