)It is (has been)+
时间段
+since+clause
此句型的要点
(1)
在于
since
前后句子的时态
.since
前的时 态为
is
或
has been,
后
的时态为一般过去时
Eg: It is(has been) ten years since I joined the army
译为
:
我参军已经十年了
.
要点
(2) since
后的动词若为延续性或状态性动词
,应译为否定或相反
,
若为短暂
性动词按字面意思翻译
.
Eg:1It is(has been) ten years since I was a teacher
=It is(has been) ten years since I left the army
译为
:
我复员十年了
.
It is ten years since I smoked
=It is ten years since I stopped smoking
译为
