【考點】演講稿．

【答案】Dear students，
    I am Li Hua.It's my honor to speak here today.My topic is protecting trees，they are really important in our daily lives.They help us in many ways.Trees provide us with wood and fruit.Many of the things in our daily lives come from trees.For example，paper and pencils.A lot of furniture is made of wood as well．Trees also help fight against pollution.They take in harmful gases and produce oxygen.As a result，they keep the air cool and clean.
However，people cut down millions of trees every year.It is very important for us to protect the trees．First，we must stop cutting down too many trees.Second，we should plant more trees and take good care of them.Third，we don't use throwaway chopsticks ，and we should save paper and so on.Let's do our best to make our environment greener.
