Dear friend,
Trees are our friends. They help us in many ways. They cool our cities and clean our air. They also give out oxygen for us to breathe. Trees help reduce noise pollution and make cities beautiful.
Trees provide a lot of things for people. They provide us with food. They also provide materials (材料) for houses, furniture and paper products. Trees keep the Earth from becoming too hot for us to live on. Trees also keep soil from being washed away. We need soil to plant food.
