五、 【范文】
As we all know, trees are very important to the environment.
In many ways, they help us live better. They provide us with food and materials. They also help to keep the air clean. What's more, trees can keep the climate from getting warmer. But more and more trees are disappearing around the world every year, mainly because people cut down them for the use of farming and building. So, in order to have a better future, we should plant more trees and take care of them. That's why we hold the activity called “Planting Trees for the Earth”. Let's join in it together!
Thank you for listening!

Trees are very important to us. Do you know why Let me tell you. Trees take in carbon dioxide from the air and make oxygen. That’s important. People and animals need oxygen to live. Many small animals live in the trees. Some of them also get food from trees. Trees can also prevent water and soil from going away. If we have a lot of trees, we stop deserts from being large. You know, trees are green. They can make our country even more beautiful. We should plant more trees and take good care of them.
