It ________ three years since they met in Shanghai last time.
问题描述:
It ________ three years since they met in Shanghai last time.
A.has been B.was C.is D.had been
为什么不选A
答
因为本句是描述自从她俩在上海相遇到现在是三年,it is three years 若用A就与题意不负为什么?因为本巨的主句是陈述句,要用A的话是这样才对they have been met in shanghai since three years.have been met 不就变成被动语态了吗?since three years不用加ago吗?刚太激动多打个been 没有ago,since加一段时间是现完时,一段时间加ago是一过时。since 和ago永远不能同时用(⊙o⊙)哦
