Grammar
Focus
used
to是一个固定结构，它的意思是“过去经常、以前常常”，它的后面用动词原形，它表示过去存在某种状态或者过去的某种经常性、习惯性的行为或者动作，并意味着这种动作目前已经不存在，所以它只能用一般过去时，不能用现在时态。
“used
to”
used
to
+
do
sth.
“过去常常”表示过去习惯性的动作或状态，但如今已不存在。
I
You
/We/They
He
/She/It
used
to
eat
breakfast
at
7
a.m.
every
day.
e.g.
Scarf
used
to
take
a
walk.
Mother
used
not
to
be
so
forgetful.
He
used
to
work
in
the
factory.
My
father
used
to
read
newspapers
after
breakfast.
　　
B)主语＋used
not
to
＋动词原形......
第一种否定句型，就是把used当作实义动词来看，所以变否定句要用助动词did；第二种否定句是把used当作情态动词，变否定句直接在used后面加not即可，used
not
可以缩写成usedn’t或usen’t。美式英语通常用A种形式，英式英语常用B种形式。例如：
You
didn't
use
to
drink.
She
used
to
smoke
a
lot.
Did
she
use
to
smoke
a
lot?
Used
she
to
smoke
a
lot?
Did
your
sister
use
to
be
quiet?
Used
to
的一般疑问句形式
(四)
used
to
的状语可以用副词always，often，sometimes等，但是仍然是过去的习惯，不是指现在的习惯，所以不能用一般现在时。
例如：He
always
used
to
be
late
for
class.
他过去常常上课迟到。
(五)
used
to可以用在there
be结构中表示“过去经常有”的意思。
There
used
to
be
There
used
to
be
a
lot
of
teachers
in
the
school.
100
years
ago,
there
used
to
be
a
beautiful
village
in
the
country
There

to
be

clever
old

the

to

sth.
