Trees are our good friends. They help us in many important ways. First, trees provide us with fresh fruit. We can enjoy apples, oranges, pears and peaches from trees. These fruits are full of vitamins and good for our health. Second, trees give us wood. People use wood to make many things, like desks, chairs, beds and paper. Even some houses are made of wood. Third, tree leaves are like "air cleaners". They take in bad gases and make the air clean. Breathing clean air helps us stay healthy. Fourth, the roots of trees are strong. They hold the soil tightly and keep it from being washed away by rain or wind. This helps protect our environment.
In a word, trees are very important for us. We should plant more trees and take good care of them.
