第三节几何课,太阳死气沉沉地照着,空气也热闷闷的。我班同学这会儿都皱着眉头,烦闷得很——不仅是因为这可恶的天气,还有老师在黑板上写的那道可恶的题。“铃……”下课了,我班同学就像有指挥似的,“刷”地趴在桌子上。之后,班级里死一般的寂静。过了一会儿,今天值日生娄伟走到讲台去,擦起了黑板。粉笔灰随着他手中黑板擦的挥动而飘散开来,坐在前面的同学都怕吸 In the third quarter of the geometry class, the sun was silently still and the air was hot and stuffy. My classmates were frowning and frustrated at the moment - not only because of this terrible weather, but also the daunting question written by the teacher on the blackboard. “The bell ...” class, my classmates like commanding, “brush” to kneel on the table. Afterwards, the silence in the class was dead. After a while, today, Sheng Wei went to the podium and wiped the blackboard. The chalk dust drifted away with the wiping of the blackboard eraser in his hand. The classmates sitting in front were afraid to suck.
