虚拟语气中if条件从句中又包含其他从句应该怎么办?

题目

虚拟语气中if条件从句中又包含其他从句应该怎么办?
比如我想说
如果我昨天有仔细听老师在课堂上讲的重点内容,那么现在我就不会尴尬了
这个if 条件句中还有从句不知道怎么弄时态
if i had attentively listened to the key which my teacher discoursed yesterday,i would not have been awkward.
如果我仔细听老师昨天论述的要点,我现在就不会尴尬了
在这个小从句中 时态应该怎么写?
my teacher discoursed yesterday
假如换成after 或者before 来引导又怎么办呢?
if i had finished doing my works after he come home,i would not have been condemned by him
这个after he come home 引导的从句 时态应该怎么弄?
还有i would not have been condemned 这句
我故意把 被动与否定连起来了
