Passage1（课内同源：校园绿色周）

　　This week is Green Week at our school. The students are doing many things to protect trees and save the environment. / On Monday, Class One made a big poster. It says “Save Paper, Save Trees”. They put it at the school gate so that every student can see it. On Tuesday, the volunteers collected waste paper from every classroom. They took it to the recycling centre and got new notebooks in return. / On Wednesday, Class Two planted twenty young trees behind the library. They water the trees every morning before class. On Thursday, a scientist came to our school and gave a talk. He told us that one big tree can give us enough oxygen for two people for a whole year. / Green Week ends on Friday, but our work does not end. We will keep saving paper and looking after our trees.
