“丁零零……”上课铃响了。老师脸上堆满微笑走进来,紧跟在后的有30多位来听课的老师。自我进入小学以来,这还是第一次。可是同学们好像没事一般,个个镇定自若。开始上课了,老师有声有色地讲着,可是我们呢,都无精打采。原来,为了迎接这堂公开课,我们整整排练了三遍。提问、回? “Ding small zero ...” The bell rang. The teacher came in full of smiling faces, followed by more than 30 teachers to attend classes. This is the first time since I entered primary school. However, students seem normal, all calm. Start class, the teacher speaks vividly, but we, are listless. It turned out that, in order to meet this open class, we rehearsed the entire three times. Ask questions, back?
