六、阅读理解。
Trees are very important in our life. They are one of the biggest and oldest living things on Earth. Many things come from trees, for example, the wood in your pencil and the paper in your notebook. Trees can fight pollution, and they can cool and clean the air. Trees can also communicate(交流) with one another to protect themselves from insects(昆虫).
But now trees are in great danger. People cut down and burn(燃烧) many trees every year. Trees are our friends. Let's try our best to plant more trees and protect them.
