Do you know Planting Day? On that day,many people are going to plant trees.Last weekend, my family and i went to Zhongshan Park to plant some trees.We were very tired but happy.My father planted the trees, and my mother watered the trees, I saw my father and mother doing this and learnt a lot .We all know that our city becomes dirtier and dirtier, but why don't we push our hands to save the enviroment?Planting Trees is a good way to improve the enviroment,let's go and try our best to protect the environment and plant more trees.I believe our city will be more beautiful one day.
