【答案】Dear Friends，
         Recently，it has been common that people waste a lot，so there has been an activity of "doing your bit for an energy-saving society" in our school.Our schoolmates are highly concerned about the increasing lack of energy and provide their own suggestions.
 ???   Some students suggest that we shouldn't waste any food or paper，though they appear very easy to get.Meanwhile，some other students think it advisable to refuse to use disposable chopsticks and plastic bags.Besides，it is also strongly recommended that those used textbooks as well as reference books of graduates，which are still in good condition，not be thrown but recycled.
 ??    Actually，there are still quite a lot that we can easily do：say，try to take buses or ride bicycles instead of driving cars，etc.All of these will definitely help to build an energy-saving society.
With best wishes，
Li Hua
