假设你校开办以man and nature 英语演讲比赛,写一篇演讲稿，

Dear friends,
We are graduating from school now. Most of our textbooks will be useless.what a great waste to throw them away! Would you mind sending these textbooks to the younger students? Some students come from poor families.
With our help, they'll save a lot of money. In this way, we can also save some resources, for example, wood and water.
We should use our books correctly and keep them clean. So others can read easily. To share with others is happy. Helping
people in trouble is helping ourselves, too. We should take an active part in this work. It can make our school life more
meaningful. Let's make our life more colorful.That's all.
Thank you.
