When the roles of teacher and learner are seen for what they are,and when both teacher and learner fulfil them appropriately,then much of the pressure and feeling of failure for both is eliminated.另外主句是哪个呀?分析下句子结构谢谢
答
then much of the pressure and feeling of failure for both is eliminated.是主句，前面是条件“当XXXX得时候，当XXXX得时候”
答
一楼分析得对对，翻译如下：
当老师和学生明确了各自的职责并且都恰当地履行了自己的职责，那么可以消除很多的压力和失败感。
答
主句是最后一句
两个when后面的句子都是表示条件,表示在某种条件下
最后一句则是在这些条件下的结果,
翻译：当老师和学生的角色明了清晰,并且两者都可以很好的充当自己的角色,那么他们的大量压力和失落感就会随之消失!
