It is 3 years since we were married.
严格地说是病句,since后加表一个短暂动作的动词,而不是表状态或延续性动词.
指从这个动词终止算起,经过了多久.
it is 2 weeks since i borrowed that book.
be married,表状态,两人一直维持着婚姻状态,married,形容词化动词过去分词.
"since we were married" really does not make since.
那样就对了,从“他们的婚姻结束”算起.但很少are married这么说.
since i was a student it's 3 years,而不说since i was bein' a student it's 3 years.
