Green Action in Our Class
Apr1112 is memorable because our class had a meaningful experience on that day. In themoming, we bicycled to the suburbs to plant trees, talking and laughing all the way. Upon arrival,we began to work immediately. Some were digging holes. Some were carrying and planting youngtrees. Others were watering them. After getting the work done, we put up a board reminding people toprotect the trees. Before leaving we took some photos to record our green action. Seeing the lines oftrees, we all had a sense of achievement. We feel it's our duty to protect and beautify ourenvironment.
