传统的课堂听说教学往往是一盘磁带、一部录音机 ,基本上是教师放录音 ,学生听 ;教师指导 ,学生听 ;大家轮流练 ,这就造成了成绩好的学生“吃不饱”,学习困难的同学“吃不了”的状况 ,这种情况在先进的语音实验室教学模式中是不存在的。取而代之的是每个学生都可以成为教与学的 The traditional classroom listening and speaking teaching is often a tape and a tape recorder. Basically, the teacher puts on the tape and the students listen; the teacher instructs and the students listen; everybody takes turns practicing, which results in good students who are “not enough to eat”. The situation that the students with learning difficulties can’t eat can not be found in advanced speech lab teaching mode. Instead, every student can be taught and learned.
