放学预备铃响,我走进教室准备布置家庭作业,却见教室里的学生吵的闹的跑的喝水的无所不有,忙得不可开交,铃声对他们丝毫不起作用,估计刚刚上的是体育活动课,学生一个个兴奋得头上冒汗,连我进去,也只有几个同学注意到,牵前拉后地叫着“不要吵“”请安静”。教室里无比嘈杂的噪音 After school ready bell, I went into the classroom to prepare for homework assignments, but see the students in the classroom noisy running downtown drinking, busy, ringtones did not work for them, it is estimated that just Is a physical activity class, students sweating excitedly one by one, and even I go in, only a few students noticed, pull the front and shouted “Do not be noisy,” “Please quiet.” Very noisy classroom noise
