时态
谓语动词按其表示的动作或状态出现的时间和式态分成十二类,统称<动词>的<时态>。
英语<动词>的式态分为简单式,<进行时>,<完成时>,<完成进行时>四种;每种式态再按时间分为现在时,过去时,将来时三种。
<过去完成时>的形式是had+过去分词。
<过去完成时>表示过去某一时间或某一动作之前已经完成的动作或存在的状态,这一过去的时间可由by,before引导的时间<副词短语>或<从句>或从上下文中表示出来。
I had finished typing before lunch.
我在午饭前已打完字。
<过去完成时>表示过去某一时间以前开始一直延续到那个时间并可能继续下去的动作或状态,常和by或since引导的表示时间的<短语>或<从句>连用。
He had studied English for five years when he took the exam.
到考试时止,他已经学了五年英语。
<过去完成时>可表示过去未实现的希望或计划。
I had hoped to pass examination.
我曾希望能通过考试。
<现在完成时>表示到现在为止已完成或仍在持续的动作,状态;强调对现在情况的影响,联系,或表示经历,经验。

<现在完成时>是用过去发生,到现在已完成或刚完成的动作来说明现在的情况,或说明到目前为止共完成的动作。
I have opened the door.

Where did you go just now?
2)表示在过去一段时间内,经常性或习惯性的动作。

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。

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。)
Mrs. Darby has lived in Kentucky for seven years.
( 含义:现在还住在肯塔基州,有可能指刚离去)
注意: 用过去时表示现在,表示委婉语气。
1)动词want, hope, wonder, think, intend 等。
Did you want anything else?
I wondered if you could help me.
2)情态动词 could, would.

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。
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?

(错)Tom has written a letter to his parents last night.
(对)Tom wrote a letter to his parents last night.
过去完成时
1) 概念:表示过去的过去
----|-------|-----|---->其构成是had +过去分词构成。
那时以前 那时 现在
2) 用法
a. 在told, said, knew, heard, thought等动词后的宾语从句。
She said (that) she had never been to Paris.
b. 状语从句
在过去不同时间发生的两个动作中,发生在先,用过去完成时;发生在后,用一般过去时。

c. 表示意向的动词,如hope, wish, expect, think, intend, mean, suppose等,用过去完成时表示"原本…,未能…"
