导言
我们前面所学的四种时态,表达的只是时间概念。
本课所学的进行时态除时间概念外,又加入了某种感情
色彩。 在传统的教学中,进行态往往被认为只是表示一
个进行的动作,其实这只是一个表面现象,进行态更多
的含义在于给人一种生动的画面感。 我们可以形象地比
喻:使用一般态像听录音机,使用进行态则像看电视机,
而后者所具备的功能正是画面,这恰恰是一般态和进行
态的不同之处。第二,进行态给我们的是一种暂时性。
理解以上两点是非常重要的。
请大家看下列表格,竖行表示时间概念,横行则表示
情态或叫做情感。将“时”与“态”
区分开,是我们学好时态的关键。
态 一般
进行 完成 完成进行
时
现 在 一般现在时 现在进行时 现在完成时
现在完成进行时
过 去 一般过去时 过去进行时 过去完成时 过去完成进行时
将
来 一般将来时 将来进行时 将来完成时 将来完成进行时
过去将来 一般过去将来时
过去将来进行时 过去将来完成时 过去将来完成进行时
▲ 进行时态的构成
时 态 主谓宾
现在进行时 is (am, are) doing
过去进行时
was (were) doing
将来进行时 will be doing
过去将来进行时 would be doing
Be doing

现在进行时
1、进行态的暂时性,进行时态与一般时态的比较
● They live in America.(一贯的)
●
They are living in America.(暂时的)
第二句给我们的感觉是,他们一直住在别的什么地方,但目
前暂住美国。
He
is studying English
hard.
You do
not eat much.
You are not eating much.
● My TV works well.
我的电视非常好。(一贯的)
● My TV is working well.
我的电视目前很好。(暂时性)
第二句给人的印象是:电视过去工作不正常,最近修了一下,
效果很好。
2. 进行时态的感情色彩。
进行态除了表示一个进行的动作以外,更多的是带
有一种“态”,
也就是说有一种情态在里面。注意下面句子的比较:
●
More and more people buy TV sets.
● More and more people are buying TV sets.
越来越多的人买电视机。
注:第一句话只是说出一个现象,第二句话却
给了我们一个生动的画
面,试图让我们看到人们购买电视机的情景。
It
rained下雨. It was
raining.
The girl
cried哭. The girl was
crying.
-------- I had very good seat. The play was
very interesting.
I did not enjoy it.
A
young man and a young woman
were sitting
behind me. They
were talking
loudly.
●
Do you know your wife
was having
dinner with a guy
in the
restaurant near our school yesterday evening
注:说话的人没有用一般过去时,而是用过去进行时态。从这句话
中可以看出他通过进行时态的画面感,给对方一个亲眼看到的感
觉,以刺激听话的人。
你知道不知道你的老婆昨天晚上和一个小伙子在学校附近的
餐馆一起吃饭
▲ 将来进行时态
● I will wait等待for you
at the airport.
● I
will be waiting
for you at the airport.
第一句用的是一般将来时态,第二句用的是将来进行时态。第二
句
给人的感觉好像能够看到说话的人将在机场等待的情景,所以更
亲切、更踏实。这就是画面感的效果。我
们很难用汉语表达出上面
两句话的不同。

、
完成时态通常表示已完成或从事的动作。它可分为:
1. 现在完成时
(1)现在完成
时用来表示对目前状况仍有影响的,刚刚完成的动作
(常与yet,already,just连用),
或者过去某一时刻发生的,持续到现在的情况(常与
for,since连用)。例如:
1)I have just finished my homework.
2)Mary has been ill for three days.
(2)常与现在完成时连用的时间状语有:since, for, during,
over
等引导出的短语;副词already, yet, just, ever, now,
before, often, lately, recently
等;状语词组this week
(morning, month, year), so far, up to now, many
times, up to
the present等。例如:
1)I haven’t
been there for five years.
2)So far, she
hasn’t enjoyed the summer vacation.
3)There
have been a lot of changes since 1978.
(3)完成时态可用在下列结构中:
This (That, It) is (was)
the first (second…) time +定语从句;This (That, It) is
(was)
the only (last) + n +定语从句;This (That,
It) is (was) +形容词最高级+ n +定语从
句。如果主句的谓语动词是一般现在时,
从句的谓语动词通常用现在完成时;如果主句谓语
动词是一般过去时,从句谓语动词通常用过去完成时。
例如:
(1)This is one of the rarest questions
that have ever been raised at such a meeting.
(2)There was a knock at the door. It was the
second time someone had interrupted
me that
evening.
2. 过去完成时
(1)表示过去某时间前已经发生的动作或情
况,这个过去的时间可以用by,before等介
词短语或一个时间状语从句来表示;或者表示一个动
作在另一个过去动作之前已经完成。例
如:
1)We had just had our
breakfast when Tom came in.
2)By the end of
last year they had turned out 5, 000 bicycles.
(2)动词expect, hope, mean, intend, plan,
suppose, wish, want,
desire等用过去
完成时,表示过去的希望、预期、意图或愿望等没有实现。例如:
I
had meant to take a good holiday this year, but I
wasn’t able to get away.
另外两种表示“过去想做而未做的事”的表达方式是:
1)was were + to
have done sth, 例如:
We were to have come
yesterday, but we couldn’t.
2)intended
(expected, hope, meant, planned, supposed, wished,
wanted, desired) +
to have done sth, 例如:
I meant to have told you about it, but I forgot to
do so.
(3)过去完成时常用于以下固定句型:
1)hardly, scarcely, barely + 过去完成时+ when +
过去时。例如:
Hardly had I got on the bus when it
started to move.
2)no sooner +过去完成时+ than
+过去时。例如:
No sooner had I gone out than he
came to see me.
3)by (the end of )
+过去时间,主句中谓语动词用过去完成时。例如:
The experiment had
been finished by 4 o’clock yesterday afternoon.
3. 将来完成时
将来完成时表示在将来某一时刻将完成或在另一个未来的动作发生之前已
经完成的动作;也
可以用来表示一种猜测。常与将来完成时连用的时间状语有:by (the
time the end of )
+ 表示将来时间的短语和句子;before (the
end of ) + 表示将来时间的词语或句子;when,
after等加上表示将来动作的句子等。例如:
1)By this time
tomorrow you will have arrived in Shanghai.
2)I shall have finished this composition
before 9 o’clock.
3)When we get on the
railway station, the train will probably have
left.
4. 完成进行时
完成进行时是完成时的强调形式,有现在完成进行时,过去完成进行时,将来完成进行时。
(1)现在完成进行时表示过去某一时刻之前开始的动作或状态一直延续到过去某一时刻。例
如:
I have been looking for my lost book for three
days, but I still haven’t found it.
(2)过去完成进行
时表示过去某一时刻之前开始的动作或状态一直延续到过去某一时刻。例
如:
It had
been raining cats and dogs for over a week and the
downpour had caused landslides
in many places.
(3)将来完成进行时表示在将来某一时刻之前开始的一个动作或状态一直延续到将来某一时
刻
。例如:
By the time you arrive tonight, she will
have been typing for hours.
