题目

It is/has……since……的一个问题.
It is/has……since……这是一个句型.有个网友说since后面如果接的是短暂性动词,就是否定的意思.
eg:It has been 3 years since she got married.意思是她离婚有三年了.
我怎么记得since后面跟短暂性动词就是直译啊,这句话应该是她结婚三年了?

答案

一段时间 +since
表示从这个时间开始到现在---自从~~~以来
用法上It + ( 现在完成时 ) + 一段时间+ since + ( 一般过去时 )
例句：
1. It is / has been four days since I caught a cold. 我感冒已四天了.
2. It is / has been two weeks since we met last. 自从我们上次见面以来已过了两周.
我们会发现“It is +段时间＋since…..句型”在翻译成中文时,有绝然相反的两种意思,一是,“.做...有多长时间了.”另一是“.有多长时间没做...了.”怎样以简洁的讲解让学生明了.我的意思是：先让比较两个句子的意思（中英文对照）.如,
It is five years since he became a soldier.他当兵已经五年了.
It is five years since he was a soldier..他不当兵已经五年了.
再如,
It is two weeks since he fell ill .他病了两星期了.
It is two weeks since he was ill. 他病愈两星期了.
让学生观察since 从句中动词的特点吧.第一种情况的动词是短暂性动词.表示从这点开始.而第二种则是状态性的,可延续的.
