It is +段时间＋since+主语＋did.请比较：It was +段时间＋since+主语＋had done.如：It is five years since he left here.他已经离开这儿五年了.It was five years since he left here.（同上） 请问第二句不是应该用it was five years since he had left here It is five years since he lived here.他从这儿搬走已经有五年了这句话为什么是这么翻译
问题描述：
It is +段时间＋since+主语＋did.请比较：
It was +段时间＋since+主语＋had done.如：
It is five years since he left here.他已经离开这儿五年了.
It was five years since he left here.（同上）
请问第二句不是应该用it was five years since he had left here
It is five years since he lived here.他从这儿搬走已经有五年了
这句话为什么是这么翻译
答
你所说的是正确的it was five years since he had left here 这句是对的.
It is five years since he lived here.他从这儿搬走已经有五年了.(因为这句中动词是延续性动词,所以要从动作结束时算起)
再如It is five years since I came here.我来这已经五年了.(这句中的come是非延续性动词,所以要从动作开始时算起)
