since和过去完成时的搭配
@南帜1131：since和过去完成时能否搭配 -
蔚良17862826575…… since的意思是自从,不能与完成时态连用,一般用法是 1.主句完成时,从句since+时间点 2.主句完成时,从句since+过去时态 3.It has been+时间段,since+过去时态 例如: I haven't heard from him since last year.我自去年以来未曾收到过他的信...
@南帜1131：完成时和过去完成时句子中since后面接什么时态 -
蔚良17862826575…… 一般情况是since前面的失态比其后面的要晚一个时态,比如: it has been ten years since he left home.他离家已经十年了(到目前为止). 离开家是已经发生了的事情,要用过去式的.从离开家开始算到现在已经十年了~~就用现在完成时,表示对现在的影响,即现在还没回家. 希望你能明白了~~O(∩_∩)O~
