牛津译林英语八年级上Unit8 Natural disasters Grammar ：Past Continuous tense学案（1课时无答案）

过去进行时
一．过去进行时的构成形式
由“was/were
+
v-ing”构成，如：
She
was
watching
TV
at
9:00
yesterday
evening.
昨晚九点钟她在看电视。
They
weren’t
playing
football
at
that
time.
那时他们不在踢球。
Were
you
doing
your
homework
this
time
yesterday?
昨天这个时候你正在做作业吗？　
二．过去进行时的用法
1.
过去进行时的基本用法
　
过去进行时主要表示过去某一时刻正在进行或过去某一阶段一直在进行的动作,
常和then,
at
that
time,
at
eight
yesterday,
this
time
last
night,
the
whole
night,
those
days,
from
one
to
five
yesterday等时间状语连用。如：
What
were
you
doing
at
nine
last
night?
昨晚九点你在做什么？
　　We?were?expecting?you?yesterday.?我们昨天一直在等你。
I
was
having
a
talk
with
Li
Hua
at
that
time.
那时，我正在跟李华谈话。
I
was
doing
my
lessons
then.
那时，我在做功课
2.?过去进行时表示现在
　用过去进行时表示现在主要是为了使语气委婉、客气。如：
　
I?was?wondering?if?you?could?give?me?a?lift.?我不知你能否让我搭一下车。
　　We?were?hoping?you?would?stay?with?us.?我们很希望你能跟我们住在一起。
　　How?much?did?you?want?to?spend,?sir??先生，您打算花多少钱？
　【注】一般过去时也有类似用法，但比较而言，用过去进行时显得更客气，更不肯定
3.?过去进行时表示感彩
　　与现在进行时相似，过去进行时也可表示满意、称赞、惊讶、厌恶等感彩，也通常与?always,?forever,?continually等副词连用。如：
　　They?were?always?quarrelling.?他们老是吵架。
　　The?boy?was?continually?asking?questions.?这个男孩子老是问东问西的。
He
was
always
thinking
of
others.
他总是想到别人。
4.?动词be的过去进行时
　　动词be的进行时也可表示过去一时的表现或暂时的状态。比较。如：
　　He?was?friendly.?他很友好。(指过去长期如此)
　　He?was?being?friendly.?他当时显得很友好。(指当时一时的表现)
5.在复合句中
（1）当表示在某事发生前开始的动作时,
用过去进行时表示过去正在进行的情况和动作,
用一般过去时表示比较短暂的动作或事件。正在进行的动作或当时的情况往往由连词when,
as,
while等引导。如：
Jane
met
Frank
when/as/while
she
was
living
in
Hollywood.
简住在好莱坞时，认识了弗兰克。
He?fell?asleep?when?he?was?reading.?他看书时睡着了。
（2）当表示同时进行的动作时，用while连接，强调同时进行的两种或几种动作，如
While
I
was
working
in
the
garden,
my
mother
was
cooking
dinner.
我在花园里干活时，我妈妈正在做饭。
　He?was?playing?while?I?was?studying.?我在做功课时他在玩。
三、过去进行时与一般过去时的区别
　　(1)
过去进行时强调动作在过去某时刻正在进行或持续，而一般过去时表示动作的完成。如：
　　He
was
writing
his
composition
last
night.
他昨晚在写作文。(不一定写完)
　　He
wrote
his
composition
last
night.
他昨晚写了一篇作文。(已经写完)
　　(2)
表示过去的状态、感觉及心理活动的静态动词(如like,
love,
hate,
fear,
own,
hear,
see,
know,
want,
notice)可用于一般过去时，但通常不用于进行时。如：
　　I
hated
it
when
a
man
spoke
with
his
mouth
full
of
food.我讨厌人们说话时口里含着食物。
　　(3)
一般过去时与always,
constantly,
forever,
continually等连用，表示“过去经常性、习惯性的动作”；而过去进行时与always,
constantly,
forever,
continually等连用，表示动作的重复，常带有感情的色彩。如：
　　He
always
got
up
at
six.
他过去总是六点起床。
　　He
was
always
thinking
of
his
work.
他总是一心想到工作。
　　(4)
有时过去进行时可以用来替换一般过去时，但一般过去时表示主语的行为是经过认真考虑的；而过去进行时表示一种较随便或没有进行仔细考虑的行为。如：
　　I
thought
that
he
would
agree
with
us.
我原以为它会同意我们的。
　　I
was
thinking
of
persuading
him
to
follow
my
advice.
我想到了要说服他接受我们的建议。
