it‘s about fifteen years since they got married跟they have been married for about fifteen years

问题描述:

it‘s about fifteen years since they got married跟they have been married for about fifteen years
两者有区别吗?
可如果翻译的话......那不是跟后者不相同了吗?

两者表达的意思是一样的.
不同意楼上说法,have been married 在这里是指一个状态,相当于BE动词加形容词.
翻译直译的话:前者是-自从他们结婚已经15年了,后者是-他们已经结婚15年,其实意思是一样的,只不过英文的表达方式比较丰富,楼主不要钻牛角尖.
