初中英语八大时态结构及用法
时态无疑是初中英语最重要的语法内容,学好时态基本就拿下了
语法的半壁江山。
英语八大时态:
一、一般现在时
标志:动词原形
1. 表示经常性或习惯性动作,常与表频度的时间状语连用:
She
often speaks English.
I leave home for school
at 7 every morning.
2. 表示现在的状态、特征、职业、能力、感觉等:
He seems to feel a bit down today.
He
works as a driver.
3.
表示真理、客观存在、科学事实或用于格言警句中:
Shanghai lies in the
east of China.
Columbus proved that the earth
is round.
Where there is a will, there is a
way.
4. 表示现在瞬间的动作:
Here comes the bus!
5. 表示将来:
1)表按规定、计划、安排将要发生的动作(仅限于某些表示“来、
去、动、停、开始、结束、继续”等的趋向动词),可以与表示未来
的时间状语搭配使用。常见的用法
是:飞机、火车、轮船、汽车等定
期定点运行的交通状况。如:
The next
train leaves at 3 o’clock this afternoon.
How
often does the shuttle bus run?
2)在时间和条件状语从句中常使用一般现在时表示将来发生的事情:
When Bill
comes(不用will come)ask him to wait for me.
I
shall go there tomorrow unless I’m too busy.
二、一般过去时
标志:动词过去式
闭音节:元音字母a, e, i, o,
u如果发字母本来的音则称为开音节,否
则称为闭音节。
1.
表示过去某时所发生的动作或存在的状态,常与表示过去的时间
状语连用(e.g.
yesterday, this morning, just now, a moment ago,
in May,
last night year week, once upon a
time, the other day, before …,
when …, in the
past等)。如:
Jim rang you just now.
Liu Ying
was in America last year.
2.
表示过去经常或反复发生的动作,特别是used to
do表达的句型,
本身表示的就是过去常常。如:
When I was a kid, I
often played football in the street.
She used
to visit her mother once a week.
注意区分sb. used
to do sth.(某人过去常常做某事,此处to是动词不
定式标志符号)和sb. be
used to sth.(某人习惯于某物做
某事,此处to是介词)。
3.
代替一般现在时,表示一种婉转、客气、礼貌、商量的语气。此
用法仅适用于少数动词(如want,
hope, wonder, think, intend等)及
情态动词could,
would。如:
I wondered if you could have a word
with me.
I hoped you could help me with my
English.
Would you mind my sitting here?
4. 虚拟语气中用一般过去时表示现在或将来时间的动作或状态。常

三、一般将来时

the snow will start to melt.

五、过去进行时
标志:was were + 动词的现在分词

注意:瞬间动词通常是不能用现在完成时表持续性的,但其否定结构

6)This is + 形容词最高级
+ that … 这是最…

(ever)seen.
6. 现在完成时与一般过去时的区别
1)现在完成时强调对现在的影响和结果,与现在有联系;
而一般过去时强调这个动作发生的时间是在过去,不涉及对现在的影
响。如:
I have seen this film. (我已经看过了这部电影)
I saw this film yesterday. (我是昨天看的这部电影)
2)现在完成时常与模糊的时间状语连用(如for, since, so far, ever,
never, just, yet, tilluntil, up to now,
always等),或者干脆没有时间状语;
而一般过去时常与具体的时间状语连用(如yesterday, last night,
…
ago, in 1980, in February等)。
3)现在完成时表示持续时一般使用延续性动词(如live, teach, work,
know等);
而一般过去时常使用瞬间动词(如begin, buy, die,
marry等)。如:
He has lived in Hangzhou since last
spring.
My grandfather bought the car five
years ago.
7. 易错点辨析
1)
考生容易把一些瞬间动词用现在完成时表达,这是错误的。如:
(×)He has died
for two years. 他死了两年了。
(√)He has been dead for
two years.
(√)He died two years ago.
(×)The film has begun for 10 minutes.
电影开演十分钟了。
(√)The film has been on for 10
minutes.
(√)The film began 10 minutes ago.
(×)She has married for three years. 她结婚有三年了。
(√)She has been married for three years.
(√)She married Mike three years ago.
2)考生不懂如何区分have been to和have gone
to,尽管两者均可后
接地点,但have been
to表示去过某地(现在已经回来了),have gone
to表示到某地去了(现在还没回来)。如:
She has been to Paris
(three times).
She has gone to Paris.
七、过去完成时
标志:had +动词的过去分词
1.
表示在过去的某个时间或动作以前已经发生的动作或已经存在的
状态。如:
By the
end of last week he had finished the work.
He
had left when I arrived.
2.
表示从过去某一时间开始,一直延续到过去另一时间的动作或状
态。如:
We had
not seen each other since I left Beijing.
The
film had been on for 5 minutes when I got to the
cinema.
3. 某些表意向的动词(如intend, think, plan,
expect, hope等)的过去
完成时表示主语未曾实现的愿望、希望、打算。如:
I
had intended to visit you last night, but someone
called and I couldn’t
get away.
We had
hoped that you would come, but you didn’t.
4. (虚拟语气)在条件状体从句或wish would
rather等后面的从句
中,使用过去完成时表示与过去事实相反的主观愿望。如:
The
party wouldn’t have been so perfect if you hadn’t
come.
I wish I had gone with you to the
concert that day.
5. 过去完成时与一般过去时:
1)基本区别:
过去完成时表示以过去某时间为起点以前所发生的动
作或存在的状态,即过去完成时强调“过去的过去”
,而一般过去时
只表示以现在时间为起点以前所发生的事情或存在的状态。如:
He
studied there two years ago.他两年前在那儿学习(离现在两年)
He said he had studied there two years
before.他说他两年前在那儿学
习过。(离他说话时两年)
2)特别注意:两个动作如果按顺序发生,又不强调先后,或者用then,
and,
but等连词连接时,多用一般过去时。如:
When she saw the mouse,
she screamed.
My aunt gave me a hat and I lost
it.
八、过去将来时
标志:would + 动词原形
1.
表示从过去某一时间来看将要发生的动作或存在的状态,一般用
于主句为过去时的宾语从句中。如:
He said he would come here next Friday.
I
knew that he would help us when we were in
trouble.
2. 表示过去的动作习惯或倾向:
The old
man would sit on a bench in the quite park for
hours without
doing anything.
When I
worked on that farm, I would get up at 5 am.
3. 用于虚拟语气中:
If I were you, I would not do
that.
If he were here, he would show us how to
do it.
4. 过去将来时的其他形式:
1) was were going
to + 动词原形。如:
He told us that he was going to
attend the meeting.
She said that I was going
to be sent to meet her at the railway station.
2)was were to + 动词原形。如:
The building was
to be completed next month.
Li Lei was to
arrive soon.
3)was were about to + 动词原形。如:
We were about to leave there when it began to
rain heavily and
suddenly.
He was about to
have lunch when the bell rang.
