Dear teachers and classmates，

【考点】倡议书；环境保护．

【答案】Dear teachers and classmates，
    We are sorry to see so much waste in our school.I think I bear the responsibility to draw your attention to the phenomenon that a lot of things are being wasted in our school．For instance，walking around the campus，you can easily find an empty classroom with lights on．In the dining hall，large quantities of left﹣over food are thrown away every day．It's also common that many students still use disposable products for convenience，which really results in the waste of materials．
Accordingly，it is time that we took action to stop wasting on campus．First of all，it's essential for us to turn off lights and other electrical appliances when we are not using them．Besides，buy food according to what you need．We should keep in mind that every grain is the fruit of hard work．Additionally，avoid using disposable products，which will surely contribute to the reduction of waste．
Every little bit counts．Let's start from the very little things around us and stop wasting．
