总复习之动词的时态和语态
(一) 动词是谓语动所表示的动作或情况发生时间的各种形式。英语动词有16种时态,但是常用的只有9种:一般现在时、一般过去时、一般将来时、现在进行时、过去进行时、现在完成时、过去完成时、过去将来时、现在完成进行时。下面分别介绍。
1、 一般现在时的用法
1) 表示经常性、习惯性的动作;表示现在的状态、特征和真理。句中常用 often, usually, every day 等时间状语。例如:
a. He goes to school every day.
b. He is very happy.
c.The earth moves around the sun.
2) 在时间状语从句和条件状语从句中,用一般现在时表示将来。例如:
a. If you come this afternoon, we’ll have a meeting.
b. When I graduate, I’ll go to countryside.
3) 有时这个时态表示按计划、规定要发生的动作(句中都带有时间状语),但限于少数动词,如:begin, come, leave, go ,arrive, start , stop, return, open, close等。例如:
a. The meeting begins at seven.
b. The rain starts at nine in the morning.
4) 表示状态和感觉的动词(be, like, hate, think, remember, find, sound 等)常用一般现在时。

2.一般过去时的用法
1) 表示过去某时间发生的事、存在的状态或过反复发生的动作。
a. He saw Mr. Wang yesterday.
b. He worked in a factory in 1986.
2)表示过去经常发生的动作 , 也可用 “used to “I used to smoke.
3.一般将来时的用法
一般将来时表示将来的动作或状态。其表达形式除了 “ will 或 shall + 动词原形 ”表示即将发生的或最近打算进行的事。
It is going to rain.
We are going to have a meeting today.
2)“be to + 动词原形” 表示按计划进行或征求对方意见。
The boy is to go to school tomorrow.
Are we to go on with this work?
3) “be about to + 动词原形” 表示即将发生的动作,意为 be ready to do sth. 后面一般不跟时间状语。 We are about to leave.
4) go , come , start, move, sail, leave, arrive ,stay 等可用进行时态表示按计划即将发生的动作。I’m leaving for Beijing.
4.现在进行时的用法
1) 现在进行时表示现在正在进行的动作,由“be + 现在分词” 构成。另外, “系动词 + 介词或副词” 也表示进行时的意义。What are you doing? The bridge is under construction.
2) 表示感觉、愿望和状态的某些动词(如have, be , want, like 等 ) 一般不用进行。
5.过去进行时的用法
1) 过去进行时过去某一时刻、某一阶段正进行的动作,由 “ was (were) + 现在分词”构成。
In 1980 he was studying in a university.
He was reading a novel when I came in.
2)时间状语常有: when \ while 引导的表过去的时间状语 或具体的过去的时间点
I was eating dinner while he was watching TV.
She was reading a newspaper at eight yesterday evening.
6.现在完成时的用法 现在完成时由 “have + 过去分词” 构成
1) 现在完成时所表示的动作在说话之前已完成,但强调对现在有影响。
He has gone to Fuzhou. (现在不在这儿)
He has been to Fuzhou. (现在对福州很了解)
2) 现在完成时所表示的动作开始于过去,持续到现在,也许还会持续下去常用 for 和since表示一段时间的状语或so far , now, today, this wek (month, year ) 等表示包括现在内的状语。
He has studied English for 5 years.
He has studied English since 1985.
Now I have finished the work..
注意:表示短暂时间动作的词(如come, go , die, marry, buy 等)的完成时不能与for, since 等 表示一般时间的词连用。
7.过去完成时的用法 过去完成时由“had + 过去分词”构成
1)过去完成时的动作表示过去某一时刻或某一时刻或某一动作之前完成的动作或状态。句中常用by, before, until, when 等词引导的时间状语。
By the end of last year we had built five new houses.
I had learnt 5000 words before I entered the university.
2)过去完成时的动词还可表示过去某一时刻之前发生的动作或状态持续到过去某个时间或持续下去。Before he slept, he had worked for 12 hours.
8.过去将来时的用法
过去将来时表示从过去的某个时间看来将要发生的动作或存在的状态。过去将来时由 “should 或 would + 动词原形” 构成。第一人称用should, 其他人称用would.
They were sure that they would succeed.
9.现在完成进行时的用法 现在完成进行时由 “ have (has)+ been + 现在分词”构成
表示现在以前一直进行的动作。有些动词(work, study, live, teach 等) 用现在完成时与用现在完成时意思差不多。
I have worked here for three years.
I have been working here for three years.
但多数动词在这两种时态表示不同意思
I have been writing a letter.
注意:表示短暂动作的动词(finish, marry, get up, come, go 等)不能用这种时态。

英语共有十六种时态,其表现形式如下(以study为例):
  一般时 进行时 完成时 完成进行时
现在 study
studies am studying
is studying
are studying have studied
has studied have been studying
has been studying
过去 studied was studying
were studying had studied had been studying
将来 shall study
will study shall be studying
will be studying shall have studied
will have studied shall have been studying
will have been studying
过去将来 should study
would study should be studying
would be studying should have studied
would have studied should have been studying
would have been studying
时态(Tense)是表示行为、动作和状态在各种时间条件下的动词形式。因此,当我们说时态结构的时候,指的是相应时态下的动词形式。
英语时态分为16种:一般现在、一般过去、一般将来、过去将来时,以及这四者的进行时、完成时和完成进行时。
一. 一般现在时
用法:
A) 表示现在发生的动作、情况、状态和特征。B) 习惯用语。C) 经常性、习惯性动作。
D) 客观事实和普遍真理。尤其要注意,如果前后文不是一般现在时,则无法保持 主句、从句时态一致。
E) 表示一个按规定、计划或安排要发生的动作,(仅限于某些表示“来、去、动 、停、开始、结束、继续”等的动词 )可以与表示未来时间的状语搭配使用 。常见的用法是:飞机、火车、轮船、汽车等定期定点运行的交通方式。
 例:The next train leaves at 3 o'clock this afternoon.
(下一趟火车今天下午3点开车。)
  How often does this shuttle bus run? (这班车多久一趟?)
F) 在时间和条件状语从句里经常用一般现在(有时也用现在完成时)表示将来事情
时间状语:
  always, usually, often, sometimes, every week (day, year, month…), once a week, on Sundays, etc.
  基本结构:①be动词;②行为动词
  否定形式:①am/is/are+not;②此时态的谓语动词若为行为动词,则在其前加don't,如主语为第三人称单数,则用doesn't,同时还原行为动词。
一般疑问句:①把be动词放于句首;②用助动词do提问,如主语为第三人称单数,则用does,同时,还原行为动词。
二. 一般过去时
用法:
A) 表示过去某个时间发生的动作或情况。
B) 表示过去习惯性动作。特别是由would/ used to do表达的句型,本身表示的 就是过去时。
He used to visit his mother once a week.(他以前总是每周看望一次他的母亲。) 
时间状语:ago, yesterday, the day before yesterday, last week(year, night, month…), in 1989, just now, at the age of 5, one day, long long ago, once upon a time, etc.
  基本结构:①be动词;②行为动词
  否定形式:①was/were+not;②在行为动词前加didn't,同时还原行为动词。
  一般疑问句:①was或were放于句首;②用助动词do的过去式did提问,同时还原行为动词。
三. 现在进行时(be doing)
  概念:表示现阶段或说话时正在进行的动作及行为。
  时间状语:now, at this time, these days, etc.
  基本结构:am/is/are+doing
  否定形式:am/is/are+not+doing.
  一般疑问句:把be动词放于句首。
四、过去进行时:
  用法:
A) 表示在过去一个比较具体的时间正在发生的动作。
  例:Mary was listening to light music 10 minutes ago.(10分钟前,玛丽正在听轻音乐。)
B) 如果when, while这样的时间状语引导词所引导的主从句之一是一般过去时,则另一个句子常用过去进行时。
  例:I was washing my hair when you knocked at the front door.(你敲前门时我正在洗头发。)
  时间状语:at this time yesterday, at that time或以when引导的谓语动词是一般过去时的时间状语等。
  基本结构:was/were+doing
  否定形式:was/were + not + doing.
  一般疑问句:把was或were放于句首。
五、现在完成时(have done)
用法:
A) 表示动作到现在为止已经完成或刚刚完成。
B) 表示从过去某时刻开始,持续到现在的动作或情况,并且有可能会继续延续下去。此时经常用延续性动词。时间状语常用since加一个过去的时间点,或for加一段时间,或by加一个现在时间。
注意事项
现在完成时是联系过去和现在的纽带。现在完成时和过去时的区别在于:现在完成时强调动作的动态,或受动态的影响,是动态的结果,对现在有影响;过去时只表示过去的某个具体时间里发生的动作,与现在没有联系。
时间状语:recently, lately, since…for…,in the past few years, etc.
 基本结构:have/has + done
 否定形式:have/has + not +d one.
 一般疑问句:have或has。
六. 过去完成时(had done)  
概念:以过去某个时间为标准,在此以前发生的动作或行为,或在过去某动作之前完成的行为,即“过去的过去”。
  时间状语:before, by the end of last year(term, month…),etc.
  基本结构:had + done.
  否定形式:had + not + done.
一般疑问句:had放于句首
七、一般将来时:
概念:表示将要发生的动作或存在的状态及打算、计划或准备做某事。
  时间状语:tomorrow, next day(week, month, year…),soon, in a few minutes, by…,the day after tomorrow, etc.
基本结构:①am/is/are/going to + do;②will/shall + do.
③、be to do ④ be about to ⑤、一般现在时表将来 ⑥、现在进行时表将来。
  否定形式:①was/were + not; ②在行为动词前加didn't,同时还原行为动词。
  一般疑问句:①be放于句首;②will/shall提到句首。
分别用法:
A) 基本结构是will / shall do。
  例:We shall send her a glass hand-made craft as her birthday gift.
B) 有些动词,如:arrive, be close, come, do, done, go, have, leave, open, play, return, sleep, start, stay等,用于现在进行时,并且通常与一个表示将来时间的时间状语连用,可以表示将来时。
  例:My mother is coming to visit me next week and is staying here until May.(我妈妈下周将来看我,并会呆到5月。)
C) 表示“打算去……,要……”时,可用be going to do。
  例:This is just what I am going to say.(这正是我想说的。)
D) 表示“即将、正要”时,可用be about to do。强调近期内或马上要做的事。
  例:Don't worry, I am about to make a close examination on you.
E) "be to do" 表示“按计划、安排即将发生某事或打算做某事”。
F) 同样可以表示“正要、将要”的意思的句型是be on the point of doing。
例:The coach is on the point of giving up the game because our team has been scored 7 points.   例:2005年6月大学四级第65题
  I was _______ the point of telephoning him when his letter arrived.
  A) in   B) to   C) at   D) on
  答案是D)。on the point of doing 是固定词组,意思是“正要、打算”。全句的意思是:“当他的信到的时候我正要打电话给他。”
注意事项:
  在以if, when, as long as, as soon as, after, before, in case, until, unless等连词以及具有连词作用的副词(immediately, the moment, directly)等引导的状语从句,一般用现在时代替将来时。强调延续性或动态时,可用完成时。
  例:I hope his health will have improved by the time you come back next year.(我希望到明年你回来的时候,他的身体已经好多了。)
八、过去将来时:
  概念:立足于过去某一时刻,从过去看将来,常用于宾语从句中。
  时间状语:the next day(morning, year…),the following month(week…),etc.
  基本结构:①was/were/going to + do;②would/should + do.
  否定形式:①was/were/not + going to + do;②would/should + not + do.
一般疑问句:①was或were放于句首;②would/should提到句首。
例 I said on Thursday I should see my friend the next day.(我星期四说我将于第二天拜访我的朋友。)
九 现在完成进行时(have been doing)
用法:表示某一动作开始于过去某一时间,延续或重复地出现至今,或将继续延续至将来。
  例:We have been working on this project for over a month now.(到目前为止,我们一直在处理那个项目,已经花了一个多月时间了。)
注意事项:与现在完成时相比,现在完成进行时更强调:在从过去到现在的时间里,动作或状态一直持续或一直反复出现。
十、 将来完成时(will have done)
用法:表示从将来的某一时间开始、延续到另一个将来时间的动作或状态,或是发生在某个将来时间,但对其后的另一个将来时间有影响的动作或状态。就好象把现在完成时平移到时间轴的将来时时段一样。其用法从和过去及现在有关,变成了和将来及将来的将来有关。
 例 The conference __________ a full week by the time it ends.
  A) must have lasted   B) will have lasted C) would last     D) has lasted
以下六种时态考察较少
十一. 将来进行时(will be doing)
用法:强调在将来的某个具体时间正在发生的动作或事情。
  例:Don't worry, you won't miss her. She will be wearing a red T-shirt and a white skirt at that time.(别担心,你不会认不出她的。她到时会穿一件红色的T恤衫和一条白色的短裙。)
注意事项:由于本时态是由将来时和进行时融合在一起的,所以关于本时态的注意事项,可参考"一般将来时"和"现在进行时"的有关注意事项。
十二、将来完成进行时:shall have been doing ,will have been doing
  例:By the end of next month, the project will have been being worked for 3 years. (到下个月底为止,这项工程就已经不停地进行了3年了。)(被动语态)
十三、过去完成进行时:had been doing
  例:The old clock had been being taken apart of and fixed up again for several times by my 10-year old son before I came back home.(我回到家之前,我10岁大的儿子已经把这个旧钟表拆卸并重新组装了好几回了。)(此处强调“拆卸”和“组装”这两个过去的过去的动作一直在反复进行。)(被动语态)
十四、过去将来进行时:should be doing , would be doing
例:The government promised that a new highway would be being built next July.(政府承诺说第二年7月将有一条新的高速公路正在修建。)(此句的时间状语是具体的将来时间,所以最好用将来进行时。)(此句为被动语态)
十五、 过去将来完成时:should have done , would have done
例:I believed by the end of that year an advanced version of that software would have been developed, but I was wrong.(我坚信到那年年底为止,那个软件的新版本将被开发出来。但是我错了。)(此句为被动语态)
十六、 过去将来完成进行时:should have been doing , would have been doing
例:They said that by the end of the following month, the project would have been being worked for 3 years. (他们说到第二个月底为止,这项工程就已经不停地进行了3年了。)
