这件事情发生在我的小学时代。那天上午的第二节课是数学,并且是公开课。为了上好这节课,老师做了充分准备。因为我的普通话较好,所以老师安排我读定义。上课了,由于准备工作做得充分,所以老师讲起课来有条不紊,一切是那么的井井有序。来听课的领导们露出了赞许的微笑。 This happened in my elementary school. The second lesson of that morning was math and it was an open lesson. In order to do a good job in this class, the teacher made a full preparation. Because my mandarin is good, so the teacher arranged for me to read the definition. Class, because the preparatory work done adequately, so the teacher talked about the class method, everything is so organized. The leaders who attended the lectures showed a smile of approval.
