11. 动词的时态（一）
11.1 一般现在时的用法

school at 7 every morning.
2) 客观真理，客观存在，科学事实。

east of China.
3) 表示格言或警句中。

注意：此用法如果出现在宾语从句中，即使主句是过去时，从句谓语也要用一般现在时。

the earth is round..
4) 现在时刻的状态、能力、性格、个性。

English but does not speak well.
比较：Now I put the sugar in
the cup.

now.
第一句用一般现在时，用于操作演示或指导说明的示范性动作，表示言行的瞬间动作。再如：Now watch me, I switch
on the current and stand back. 第二句中的 now是进行时的标志，表示正在进行的动作的客观状况，所以后句用一般现在时。
11.2 一般过去时的用法
1）在确定的过去时间里所发生的动作或存在的状态。
时间状语有：yesterday, last week,
an hour ago, the other day, in 1982等。

tomorrow.
4) wish, wonder, think, hope 等用过去时，作试探性的询问、请求、建议等。

have some. 我以为你想要一些。
比较：
一般过去时表示的动作或状态都已成为过去，现已不复存在。

invalid all her life.
(含义：她已不在人间。)
Christine has been an
invalid all her life.
(含义：她现在还活着)
Mrs. Darby lived in
Kentucky for seven years.
(含义：达比太太已不再住在肯塔基州。)

else?

could help me.

be used to + doing： 对……已感到习惯，或"习惯于"，to是介词，后需加名词或动名词。

taking a walk.(现在习惯于散步)
典型例题
---- Your phone number again? I ___ quite catch it.
---- It's .
A. didn't B. couldn't C. don't D. can't
答案A. 本句虽没有明确的时间状语，但从语意上看 出，在听的时候没有听懂这个动作发生在过去，因此应用过去时。
11.4 一般将来时
1) shall用于第一人称，常被will 所代替。
will 在陈述句中用于各人称，在争求意见时常用于第二人称。
Which paragraph shall
I read first.

seven this evening?
2) be going to +不定式，表示将来。
a. 主语的意图，即将做某事。
What are you going to
do tomorrow?
b. 计划，安排要发生的事。
The play is going to
be produced next month。
c. 有迹象要发生的事

clouds, there is going to be a storm.
3) be +不定式表将来，按计划或正式安排将发生的事。

report next Saturday.
4) be about to +不定式，意为马上做某事。

return的一般现在时表将来。这主要用来表示在时间上已确定或安排好的事情。

star? It stars in ten minutes.
2）倒装句，表示动作正在进行，如：

3）在时间或条件句中。

soon as I arrive there.
4）在动词hope, take care that, make sure that等后。

arrive, leave, stay等。
I'm leaving tomorrow.
Are you staying here
till next week?
11.9 现在完成时
现在完成时用来表示之前已发生或完成的动作或状 态，其结果的确和现在有联系。动作或状态发生在过去 但它的影响现在还存在；也可表示持续到现在的动作或 状态。其构成： have (has) +过去分词。
11.10 比较过去时与现在完成时
1）过去时表示过去某时发生的动作或单纯叙述过去的事情，强调动作；现在完成时为过去发生的，强调过去的事情对现在的影响，强调的是影响。
2）过去时常与具体的时间状语连用，而现在完成时通常与模糊的时间状语连用，或无时间状语。
一般过去时的时间状语:
yesterday, last week，…ago, in1980, in October, just now, 具体的时间状语
共同的时间状语:
this morning, tonight,this April, now, once，before, already,
recently，lately
现在完成时的时间状语
for, since, so far, ever, never, just, yet, till / until, up to
now, in past years, always,
不确定的时间状语
3）现在完成时可表示持续到现在的动作或状态，动词一般是延续性的，如live, teach, learn,
work, study, know.
过去时常用的非持续性动词有come, go, leave,
start, die, finish, become, get married等。
举例：
I saw this film
yesterday.
（强调看的动作发生过了。）
I have seen this
film.
（强调对现在的影响，电影的内容已经知道了。）
Why did you get up so
early?
（强调起床的动作已发生过了。）
Who hasn't handed in
his paper?
（强调有卷子，可能为不公平竞争。）
She has returned from
Paris.
她已从巴黎回来了。
She returned
yesterday.
她是昨天回来了。
He has been in the
League for three years.
(在团内的状态可延续)
He has been a League member
for three years.
(是团员的状态可持续)
He joined the League
three years ago.
( 三年前入团，joined为短暂行为。)
I have finished my
homework now.
---Will somebody go
and get Dr. White?
---He's already been
sent for.
句子中如有过去时的时间副词（如 yesterday, last, week,
in 1960）时，不能使用现在完成时，要用过去时。
（错）Tom has written a
letter to his parents last night.
（对）Tom wrote a letter to
his parents last night.
11.11 用于现在完成时的句型
1）It is the first /
second time…. that…结构中的从句部分，用现在完成时。
It is the first time
that I have visited the city.
It was the third time
that the boy had been late.
2）This is the… that…结构，that 从句要用现在完成时.
This is the best film
that I've (ever) seen.
这是我看过的最好的电影。
This is the first
time (that) I've heard him sing. 这是我第一次听他唱歌。
典型例题
(1) ---Do you know our town at all?
--- No, this is the
first time I ___ here.
A. was B. have been C. came D. am coming
答案B. This is the first
time 后面所加从句应为现在完成时，故选B。
(2) ---Have you ____ been to our town before?
---No, it's the first
time I ___ here.
A. even, come B. even, have come C. ever, come D. ever, have come
答案D. ever意为曾经或无论何时，反意词为never，此两词常用于完成时。 This is the largest
fish I have ever seen. It is / was the first time +that-clause 的句型中，从句要用完成时。
注意：非延续性动词的否定形式可以与表示延续时间的状语连用。即动作不发生的状态是可以持续的。
（错）I have received his
letter for a month.
（对）I haven't received his
letter for almost a month.
11.12 比较since和for
Since 用来说明动作起始时间，for用来说明动作延续时间长度。
I have lived here for
more than twenty years.
I have lived here
since I was born..
My aunt has worked in
a clinic since 1949.
Some new oilfields
have been opened up since 1976.
I have known Xiao Li
since she was a little girl.
My brother has been in
the Youth League for two years.
I have not heard from
my uncle for a long time.
注意：并非有for 作为时间状语的句子都用现在完成时。
I worked here for
more than twenty years.
(我现在已不在这里工作。)
I have worked here
for many years.
(现在我仍在这里工作。)
小窍门： 当现在完成时+一段时间，这一结构中，我们用下面的公式转化，很容易就能排除非延续动词在完成时中的误使。
1) (对) Tom has studied
Russian for three years.
= Tom began to study
Russian three years ago, and is still studying it now.
2) (错) Harry has got
married for six years.
= Harry began to get
married six years ago, and is still getting married now.
显然，第二句不对，它应改为 Harry got married six
years ago. 或 Harry has been
married for six years.
