June 5^th is World Environment Day．This makes us pay more attention to our environment and the need to protect it．When Wang Boxuan，a Beijing high schoolboy，used 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，83 the money made from the sales goes towards schools in Inner Mongolia for planting trees and grass. 84 This place is one of the sources of the sandsorms that often attack Beijing during the springtime.

  Wang’s school is one of the schools in the capital that take part in the “Green

Promise” environmental 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 Gaines coming to Beijing in 2008，students are eager to help make the capital a more pleasant place，“There are some environmental 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 Peiyuan has written a letter to the teachers and students to encourage them to go on supporting environmental protection．
