Recently, Clear Your Plate campaign is more and more popular in society, which advocates saving against wasting. The campaign draws our attention to wasting on campus. Some students are noticed to throw away a lot of food in the canteen. As is often the case, some lights are still on with nobody in classrooms. What's more, many a student spends much money buying unnecessary items.
As far as I am concerned, it's high time that we fought against wasting. Here're my suggestions. Firstly, I think our school should carry out various activities to arouse students' awareness of saving. Secondly, relevant rules and regulations are supposed to be made to punish those who waste things. Most importantly, we should form the habit of saving from now. It is everybody's duty to save resources.
最近，光盘行动在社会上越来越流行，提倡节约反对浪费。这个行动引起了我们对校园浪费的注意，有些学生注意到在餐厅扔掉很多食物。通常情况下，在无人的教室一些灯仍然打开。更重要的是，许多学生花很多钱买不必要的东西。
至于我，是我们反对浪费的时候了。下面是我的建议：首先，我认为我们的学校应该开展各种活动，激发学生的节能意识。其次，相关法规应该对那些浪费行为作出惩罚。最重要的是，我们应该养成节约的习惯，从现在开始，节约资源是每个人的职责。
