涂骂14721972483问： It's +一段时间+since sb. last did sth. 某人不做某事多久了 这里的did 动词的词性有何限制吗? - ？
铜仁市碧宁回答： It's +一段时间+since sb. last did sth. 某人不做某事多久了 did必须是延续性动词.如果是瞬间动词,就翻译成,从这个动作开始到现在多长时间了 比如 it is 1 year since he smoked.就是他戒烟一年了. it is 1 year since he started smoking. 他已经抽了一年的烟了 I haven't heard from him since I lived in Beijing. 是自从我住在北京就一直没收到他的信.
涂骂14721972483问： it is ...since ..为什么不用完成时 - ？
铜仁市碧宁回答： 句型是:It's +一段时间+since+过去时(或It has been +一段时间+since+过去时) 1. It is ten years since she left me. 她离开我已经10年了. 2. It's a long time since our last vacation. 从上个假期到现在已经很久了. 3. How long is it since we visited your mother?自从我们看望你母亲以来到现在有多长时间了? 所以也可以说:it has been 100 years since Qinghua university was found.
