We plant trees because they help make our cities cool, green and free from nasty (令人不快的) pollution. With enough trees, we don’t have to use air conditioners in summer. A tree-lined avenue (街道) looks much nicer than a treeless one;
We plant trees so that there won’t be floods and fertile (肥沃的) soil (土壤) won’t be carried away;
And there are many other uses! Think of other ways that we use trees and write them down here。
