教学中笔者发现这样两种现象:一是有的学生经常有机会在集会中上台发言或演讲,他们的口才越来越好;二是每次学校举行演讲比赛,每班只能有极少数学生参加,总有一些学生因名额所限遗憾地失去登台的机会。渐渐的有登台机会的学生与因微弱差距失去登台机会的学生的口语表达能力的差 In the teaching, the author found such two phenomena: First, some students often have the opportunity to speak or give speeches during the rally. Their eloquence is getting better and better. Second, each school holds a speech contest, and only a handful of students can attend each class. To participate, there are always some students who unfortunately lose their chance to stage due to limited places. Gradually there is a difference in oral expression ability between students who have chances to step on stage and students who lose their stage chance due to a weak gap.
