“丁零零——”下课铃响了。“今天的课就上到这儿,今晚的家庭作业是抄写书后的生词……”我的话还没讲完,讲台下,学生们又像往常一样乱动起来,习惯性地收拾起各自的书包。于是我大喊一声:“安静!把家庭作业记好!”学生们才满脸不耐烦地安静下来。我压住心头的火气,接着布置作业,可刚一布置完,学生们立即像刚出笼的小鸟飞奔出去。望着这个情景我苦恼万分,为什么每到布置家庭作业,学生们仿佛一秒钟也坐不下去了呢? “Ding zero - ” The bell rang. “Today’s class is up here, tonight’s homework is a new book after copying the book ... ” my words have not finished, under the podium, the students are as usual disrupted, habitually pack up their own School bag. So I shouted: “Quiet! Good homework! ” The students calm down impatiently. I suppressed the anger of my heart, and then arranged homework, can be arranged just after the end, the students flew out like a newly-started birdie. Looking at this scene I am extremely agitated, why arrange homework every time, students seem to sit for a second too?
