Trees are our friends. We can get fresh air from trees. We can also get oxygen from
trees. The fresh air from trees can give us a fresh mind. For example, we are
tired after a long time study. When we are in the woods, we can get some fresh
air and get relaxed. The leaves of trees are green. Green color is the best
color for human eyes to relax. In order to protect trees, we should not cut
down trees for throwaway chopsticks. We should also grow more trees.
