一、一般过去式
一般过去时：
1.表示过去某个时间和现在没有联系的动作或存在的状态，常与过去时间状语连用yesterday,
last
week,
in
2000,
two
years
ago,
a
moment
ago
等。
The
boy
fell
off
his
bike
yesterday.
I
had
two
eggs
and
a
glass
of
milk
for
breakfast
this
morning.
一般过去时：
2.表示过去一段时间内经常发生的或习惯性的动作。常与often,
usually,
sometimes等连用。
I
often
went
to
school
on
foot
last
term.
He
sometimes
read
books
last
year.
一般过去时：
3.表示过去特定时间完成的有先后顺序的一系列动作。此时常常不用时间状语，而通过上下文的语境来判断。

got
up,
washed
her
face,
brushed
her
teeth,
had
her
breakfast
and
then
went
to
work.
一般过去时：
4.在表示时间或条件等状语从句中代替过去将来时。
She
said
she
would
come
if
I
promised
to
wait
for
her.
He
said
he
would
tell
her
about
the
news
as
soon
as
he
met
her.
一般过去时与现在完成时的区别？？？
1.概念不同。一般过去时只表示动作发生在过去，与现在无关，属于“过去”时态的范畴。
现在完成时强调过去发生的动作对现在的影响，属于现在时态的范畴。
2.时间状语不同。一般过去时常与过去时间状语连用，如yesterday,
last
year等。
现在完成时常与before,
already,
ever,
never,
ever
since,
since等连用。
