she did not need to take the examination again since she had already passed it 为什么不能说成she need not have taken the examination again since she had already passed it?

答案

在这里,since的意思是：因为,引导的是原因状语从句.这句话的意思是：她不需要再考试了,因为她已经通过了.所以不能说成she need not have taken the examination again since she had already passed it,因为need not have done 意思是本不需要做而做了某事,这样整句话的意思是：因为/既然她已经通过考试了,却又考了一次,不合逻辑.
