no sooner…than…
是不是不管在什么时态下~都是主语过去完成从句过去?
no sooner…than…
并注意倒装情况
再问: 也就是说都是诸于过去完成从句是过去喽?
再答: no sooner... than... "一...就..." 引导时间状语从句,主句用过去完成时,"than"后面的从句用一般过去时.(从这里可以知道,no sooner后面是主句;than后面是从句) 例: I had no sooner reached home than it began to rain. 我一到家天就下起雨来 No sooner ...than...常放在句首,表示强调.这时主句要倒装. 例:No sooner had I reached home than it began to rain. 与这个短语类似的还有 hardly ... when 意思为:"还没...就..." 例: We had hardly gotten there when it began to rain. 我们还没到那儿,天就下起雨了. (主句用过去完成时,从句用一般过去时) Hardly...when...也常放在句首 例: Hardly had we gotten there when it began to rain. 就是这样
