Dear fellow students,
 
    Our government is aiming to build a 【“conservation-oriented society” (节约型社会)】. I think it is every citizen’s duty to achieve this goal. 
    As high students, what should we do? 
    We should focus our attention on 【focus on】details around ourselves. We should form the habit of saving water,especially when we brush our teeth and wash hands, and never leave water running unnecessar-ily. Meanwhile, we ought to save electricity.When we leave classrooms or our homes we should make sure that the light and some【 electrical equipments】 have been turned off. Do never make the light on in the daytime if unneces-sary.
    We should also save our every piece of paper as well as other writing 【materials】. 【What’s more】, we should offer to recommend our relatives and friends as well as our parents to save energy. 

    Dear fellow students, 【let’s start right now】, and spare no effort to do every little bit from every detail on!
