(五)表示状态的动词不能用于现在完成进行时。

我认识他已经好几年了。

* I have been knowing...

这类不能用于现在完成进行时的动词还有:love爱,like喜欢,

hate讨厌,等。

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.

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。

When the police arrived, the thieves had run away.

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…"

We had hoped that you would come, but you didn't.

3) 过去完成时的时间状语before, by, until , when, after, once, as soon as。

He said that he had learned some English before.

By the time he was twelve, Edison had began to make a living by himself.

Tom was disappointed that most of the guests had left when he arrived at the party.

现在完成进行时 :

其构成形式如下:

I / we / they have

He / she / it has been + 动词的现在分词

功用如下:

1) 表示一个在过去开始而在最近刚刚结束的行动,如:

Ann is very tired. She has been working hard.

Why are you clothes so dirty? What have you been doing?

2) 表示一个从过去开始但仍在进行的行动,如:

It has been raining for two hours. (现在还在下)

Jack hasn’t been feeling very well recently.

3) 表示一个从过去开始延续到现在,可以包括现在在内的一个阶段内,重复发生的行动,如:

She has been playing tennis since she was eight.

4) 现在完成时强调动作行为的结果、影响,而现在完成进行时只强调动作行为本身,如:

Tom’s hands are very dirty. He has been repairing the car.

The car is going again now. Tom has repaired it.

求:现在完成进行时的用法?

现在完成时 动词发生在过去,影响到现在,延续到现在,某种经历。

句型 基本结构:主语+have/has+过去分词(done) ①肯定句:主语+have/has+过去分词+其他 ②否定句:主语+have/has+not+过去分词+其他 ③一般疑问句:Have/Has+主语+过去分词+其他 ④特殊疑问句:特殊疑问词+一般疑问句(have/has+主语+过去分词+其他) 用法 (1)定义:现在完成时用来表示现在之前已发生过或完成的动作或状态,但其结果却和现在有联系,也就是说,动作或状态发生在过去但它的影响现在还存在. I have had no money to spend now.(现在我没有钱花了.) Jane has laid the table.(简已经摆桌子.) Michael has been ill.(现在仍然很虚弱) He has returned from abroad. (现在已在此地) (2)定义:现在完成时可以用来表示发生在过去某一时刻的,持续到现在的情况,常与for,since连用. Mary has been ill for three days. I have lived here since 1998. 注意:1.现在完成时不能单独与准确时间连用, 如yesterday(morning、afternoon),last(morning、afternoon)等,除非与for,since连用. 2.现在完成时往往同表示不确定的过去时间状语连用 如already, yet, just, before, recently,still, lately等: He has already obtained a scholarship. I haven't seen much of him recently (lately). We have seen that film before. Have they found the missing child yet ? 3. 现在完成时常常与表示频度的时间状语连用, 如often, sometimes, ever, never, twice, on several occasion等: Have you ever been to Beijing I have never heard Bunny say anything against her. I have used this pen only three times. It is still good. George has met that gentleman on several occasions. 4. 现在完成时还往往可以同包括现在时间在内的时间状语连用, 如now, up to these few days/weeks/months/years, this morning/week/month/year, just, today, up to present, so far等: Peter has written six papers so far. Man has now learned to release energy from the nucleus of the atom. There has been too much rain in San Francisco this year. The friendly relations and cooperation between our two countries have been enhanced in the past few years. Up to the present everything has been successful. 5. 现在完成时表示现在之前业已完成的动作,虽然其效果或影响仍然存在但已不再继续,但是有一些现在完成时的句子,在后面加上for+一段时间,则现在完成时的动作就表示延续性. Thomas has studied Russian. (现在不再学俄语) Thomas has studied Russian for three years. (=Thomas began to study Russian three years ago, and is still studying it now.(同第2点用法第一个例句) 6. 现在完成时还可以用来表示过去的一个时间到现在这段时间内重复发生的动作. We have had four texts this semester. 现在完成时的“完成用法”和“未完成用法” 1.现在完成时的"完成用法" 现在完成时的"完成用法"指的是动作发生在过去某一时刻并已结束,但该动作对现在产生了影响,与现在情况具有因果关系。

例如:He has turned off the light.他已把灯关了。

(动作结束于过去,但说明的是现在的情况--灯现在不亮了。

) 现在完成时"完成用法"的特点是动作不延续,因此,该时态只能与表示不定的过去时间状语(如:already,yet,before,recently等)、频度时间状语(如:never,ever,once等)、包括现在时刻在内的时间状语(如:this morning / month /year...,today等)连用。

例如: Have you found your pen yet?你已找到你的钢笔了吗? 2.现在完成时的"未完成用法" 现在完成时的"未完成用法"指的是动作开始于过去某一时刻,一直延续到现在,或可能还要继续下去。

例如:He has lived here since 1978.自从1978年以来,他一直住在这儿。

(动作起始于1978年,一直住到现在,可能还要继续住下去。

) I have been in the army for more than 5 years.我在部队已经呆了五年多了。

(动作开始于5年前,一直延续至今,有可能还要继续下去。

) 此种用法的句中常需一个表示一段时间的状语(由since或for引导),或表示与现在时刻相连的时间状语(如:up to now,so far)等。

例如:I have heard nothing from him up to now.到目前为止我没有他的任何消息。

注意:(1)现在完成时的未完成用法只适用于延续性动词,不可用于终止性动词,即瞬间完成或延续时间很短的动词。

如:come,go,arrive,leave,join,become,die等。

(2)现在完成时常见两种句型: ①for短语 ②It is+一段时间+ since从句 3.一段时间+has passed+since从句 4.主语+have / has been+since短语 例如:He has been in the League for three years. 或It is three years since he joined the League. 他入团已三年了 一.have/has been doing sth. 现在完成进行时 现在完成进行时的谓语动词构成。

I/ we/ you/ they have been working he/ she/ it has been working (一)表示从过去某时开始一直持续到现在的动作,并且还将持续下去。

The Chinese have been making paper for two thousand years....

现在完成进行时的被动语态

现在完成进行时是没有被动语态的,如果有现在完成进行时的主动结构的句子变为被动结构,可以用现在完成时。

例:We have been discussing the problem for 2 days.变为:The problem has been discussed for 2 days.另外,将来进行时也没用被动语态。

例:We shall be discussing it tomorrow.变为:It will be discussed tomorrow.希望对你有帮助!

关于现在完成时,现在完成进行时的练习。

现在进行时的句子翻译出来有正在做某事的意思。

例如:I am reading.(我正在读书)注意:现在进行时的句子常常有listen,look,now等等的提示词。

现在完成时有两种用法:1.表示过去发生或已完成的某一动作或状态对现在造成的影响。

现在完成时的第一种用法和现在进行时根本没联系,很好区分。

2.表示开始于过去持续到现在的某一动作或状态。

现在完成时的第二种用法翻译出来有已经做过某事的意思,且句中常常有表一段时间的时间状语(如:for + 一段时间,since + 过去的某一时间点)且句中的谓语动词不能用短暂性动词,要用延续性动词。

举例:I am sleep. I have sleeped for 2 hours.Look!The bus is coming here.The bus has been there for 1 hour.(come是短暂性动词,他的延续性动词是be)
