3．语法
现在完成时
表示从过去已经开始持续到现在的动作或状态，可以和表示“从过去某一时刻延续到现在的一段时间状语”连用，如“for
+
时间段”、“since
+
过去时间点”、“since
+
过去时的从句”、“since
+
一段时间
+
ago”。且for与since引导的时间状语可以相互转换。
e.g.
My
uncle
has
worked
at
this
factory
for
ten
years.
=
My
uncle
has
worked
at
this
factory
since
ten
year
ago.
I’ve?lived?here?since?1990．
自从1990年以来我就住在这里。??
I?haven’t?seen?him?for?three?years.
我三年没有看见他了。?
She’s?been?at?this?school?since?five?years?ago.??
自从五年前以来她就在这个学校。
歌诀：含有for，since的现在完成时的用法歌诀:
过去的动作或状态，一直持续到现在，for、since把时间带
句中动词的特点
此种用法中表示持续性的动作或状态的动词必须是延续性动词（否定句除外）
