The Importance of Plants
My name is Li Ming. I am lucky to be here. Now, I want to say something about plants.

Plants are very common in our daily life. There are many trees and flowers around us. They are very important to us. First, plants give out fresh air for humans to breathe. Second, many of the things in our daily lives come from plants. For example, plants can give us food, wood and so on. What's more, plants can also give homes and food to animals. They help to keep the ecosystem healthy.
In a word, plants play an important part in our lives. We can't live without them. We should protect them and try our best to plant more trees every year.
