如果我是一棵大树，我会让全世界不干净的东西，吸进我的树根，让地球越变越干净。我也会给人们带来快乐，夏天的时候人们可以到树下乘凉，小朋友也可以到树下玩耍。
If I were a big tree, I would let the unclean things in the world suck into my roots and make the earth cleaner and cleaner. I will also bring happiness to people. In summer, people can go to the tree to enjoy the cool, and children can also play under the tree.
要是我是一棵大树那就好了！
If only I were a big tree!
