An interesting thing
Last Friday,our teacher told us that we were going to plant trees by the South River the next day.On Saturday morning I got up at six thirty and went to school with a bucket.My classmates were all waiting at the school gate.
When we got to the South River,we began to plant trees on the river bank.Some students dug holes ,some planted trees,and others watered the young trees .
After we finished our work,we were happy to see the young trees we plant on the river bank.
