i can't believe she‘d do that,not after all I've done for her.not在这有什么意义?

问题描述:

i can't believe she‘d do that,not after all I've done for her.not在这有什么意义?

not在这里指“我不相信她会做这件事”,即:
我不相信她会那么做,即使我已经为她做过这样的事,她也不会做的.前面不是已经有can't作为believe的否定了吗?后面的not是对前文的否定的重复,在英语中常这么用,如:Nobody believes what he says, not even me.
