语法精析
used
to的用法
1.
used
to的意思是“过去常常”,潜在的意思是现在不那样了。其中的to是不定式符号,不是介词,所以其后接动词原形(不接动名词)。如:
He
used
to
live
in
Paris.
他过去住在巴黎。
I
used
to
write
poetry
when
I
was
young.
我年轻时常常写诗。
2.
used
to的否定式和疑问式构成
used
to作为情态动词,可直接在used后加not构成否定式,直接将used置于句首构成疑问式,但与一般的情态动词不同的是,它也可像普通动词那样借助助动词did构成否定式和疑问式。如:
He
usedn't
[didn't
use]
to
come.
他过去不常来。
You
used
to
go
there,
usedn't
[didn't]
you?
你过去常到那儿去,是吗?
【注】在现代英语中,
used
to的否定式和疑问式通常借助助动词did构成(特别是在口语和非正式文中),而直接将used作为助动词用通常被认为是非常正统或过时的用法。
3.
used
to与副词连用时的位置
与
often,,
always,,
never等副词连用时,通常置于副词之后,也可置于副词之前。如
I
always
used
[used
always]
to
be
afraid
of
dogs.
我过去总是怕狗。
He
often
used
[used
often]
to
sit
outside
the
door
of
his
house.
他过去常坐他家门口。
