On 15th April,I with my classmates went to plant trees in the suburbs.We did't feel tired at all even though we cycled there. We were sorted by moniter into three groups.Each of the group had different tasks.One group was arranged to carry sapling young trees,some digged holes,the rest watered the trees.Everyone worn happiness on his or her face. After finishing our assignments,we put up a word with signs to remind people not to hurt these trees.Finally,we took a photo as a reminder. I was very happy to take actively in this activity.It was meaningful that I would never forget.The last but not least,I will try my best to protect the plants.
