It was fine on March 12 ，20xx . I got up early that day . All the students in our school went to the hill to plant trees .

We arrived at the hill at eight o'clock . The teacher asked each of us to plant at least six trees . Then we started digging， planting and watering .

We all worked so hard that we could finish our tasks ahead of tim e . Among us ，Wang Lin ，our monitor set a good example for us . Though he was ill ，he worked harder . When he finished his task ，he went on to help others without even a little rest .

He was wet all over after work .“ I must learn from him ，” I said to myself . Looking at the lines of the young trees ，we smiled happily，forgetting our tiredness .
