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 oclock . 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 .
