【答案】Dear fellow students，
As everybody can see，some resources are being wasted in our school.The lights are on during the day in some classrooms.Water taps are left running after washjye.aig.In the canteen，some students throw away their food just because they don't like it.
I think it is high time that we should stop wasting and live a low-carbon life because many people go hungry and the energy crisis is getting worse in the world.So I make the following suggestions：First，let's turn off the lights and the water taps when we don't use them.
Second，we'd better eat up the food we buy.Last but not least，we should form the habit of recycling waste.
Dear friends，if we take action now，we can make a big difference to the whole world.
