Tree Planting Day
  It was fine on March 12, Tree Planting Day. 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 holes, planting and watering the plants. We all
worked so hard that we could finish our tasks ahead of time.
Looking at the lines of the young trees, we laughed happily,
forgetting our tiredness.谢谢欣赏!
