【答案】Dear students，
   As we all know，trees are very important in our daily lives.We can't live in the world without trees.They can help us in many ways.They can help us keep the air clean and cool.And they also provide us with many useful things.For examples，we can get fruits from trees，and our furniture is made of trees.However，people cut down a lot of trees and it causes many problems.Animals are losing their homes and the number of them is becoming smaller and smaller.Without trees，some places may get flooded easily because of the decreasing of soil.There are many ways to protect the environment.We can plant more trees.And we can do some activities to stop people cutting down trees.Let's take action now to protect trees!
