Yesterday was Tree Planting Day. The teachers asked us to plant trees at the corner of our playground. At 3:00 in the afternoon, we got there. Our teacher showed us how to plant trees,then we started to do it. Some dug the pits, some put trees in them and others watered them. We planted a lot of trees. When we finished our work, it was nearly dark.

昨天是植树节，老师要求我们在操场拐角处种树。下午3点我们到了那里，老师给我们示范怎样种树，然后我们就开始干起来。一些同学挖树坑，一些同学往树坑里放树，另一些人给树浇水，我们种了很多树。当我们结束工作时，天几乎黑了。
