Answer 1

     Trees can beautify the environment and help to make the dirty air clean. They also will be good for our
health. They can not only be used for building houses and making paper, but also can be used to make many
other things. For example, many things are made of wood, so we must plant more trees and mustn't cut
down trees. We must try to keep the balance of nature.
