Waste can be seen everywhere in the school. Some students ask for more food than they can eat and others often forget (turn) off the lights when they leave the classroom. They say they can afford these things. But I don't agree with  .Waste can bring a lot of  (problem). Although China is rich in some resources, we are short of others, for example, fresh water. Itreported that we (have) no coal or oil to use in 100 years.

    So we go on wasting our resources, what can we use in the future and where can we move? Think about it. I think we should say “no” the students who waste things every day. Everybody should stop wasting as soon possible. In our everyday life, we can do many things to prevent waste from(happen), for example, turn off the water taps when we finish washing, turn off the lights when we leave the classroom, try not to ordermorefood than we need ,and so on. Little by little, everything will be changed. Waste can be  (stop) one day, if we do our best.
