自习课没有了吵闹声,大家安静学习。看到废弃物就拾起,校园路面干干净净。同学走进教室时,随手关门。清晨,我们经过走廊时,伸手关掉开着的灯。在卫生间,同学看到了水龙头没关紧,赶快拧紧它。在教室吃饭,珍惜粮食,不浪费。 There was no noise in the study class and everyone studied quietly. The waste is picked up and the campus roads are clean. As the students entered the classroom, they closed the door. In the early morning, as we crossed the corridor, we reached out and turned off the open lights. In the bathroom, the classmate saw that the faucet was not tight, and quickly tighten it. Eating in the classroom, cherishing food, not wasting.
