虚拟语气的问题it is strange that
It is amazing that he should have learnt so much in such a short time.
That he should miss such a golden opportunity!
两句话里什么时候用should do什么时候用should have done呢
答
这里两个should都是“竟然”的意思
第一句里用了should have done是表示时态
should do一般用在虚拟或表示“应当做某事”
should have done则表本该做而未做的意思,但第一句并不是用这个意思,而是表时态.
