in our daily lives（日常生活中的树）（日常生活中的树）There are many trees and flowers in the forest.Trees help us in many ways.They keep the air cool and clean.They take in harmful gases from the air and produce oxygen for us to breathe.Trees also make our lives more convenient.In fact,we get fruit and oil from trees.But now some people still cut down the trees to make money.We should stop doing this if we dont want a world without trees.Here I want to tell everyone:our forests are in danger.So lets protect the trees!
