现在完成时和现在完成进行时有什么区别

现在完成时和现在完成进行时有什么区别
现在完成时和现在完成进行时有什么区别

现在完成时和现在完成进行时有什么区别

现在完成时(Present perfect)过去发生并且已经完成的动作对现在造成影响或后果,过去某一时间开始并一直持续到现在的动作或状态。

(1)强调动作是过去发生的(2)强调对现在的影响或结果(3)在过去不确定的时间里发生的动作,但是结果对现在有影响。

现在完成进行时其表达的意思有两种:1.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。2.表示在说话时刻之前到现在正在进行的动作。现在完成进行时

其构成形式如下: I / we / they have been + 动词的现在分词

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.

注意:现在完成时有否定结构、而现在完成进行时没有否定结构。

现在完成时态可表示做完的时期以及已有的经验、但现在完成进行时不可以A) 表示动作到现在为止已经完成或刚刚完成。

ex: I have just finished my homework.

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。这里联系进行时,他们都一样,不能用短暂性动词,★★★☆☆考点。

C) 表示发生在过去,但对现在仍有影响的动作或情况。通常用点动词,如:arrive, begin, find, give, lose等。

例:John has broken his left leg.(约翰摔断了左腿。)

A) 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。

例:He worked in that hospital for 8 years.(他曾经在那家医院工作了8年。这只是讲述一个过去的事实,他现在已经不在那家医院了。)

He has worked in that hospital for 8 years.(他已经在那家医院里工作了8年。

表示他从过去开始工作,一直工作到现在,现在仍在那家医院工作。)

B) 因为含有for加一段时间或since加一个时间点这样的时间状语的完成时,有动态和延续性的特点,所以不能使用终端动词或瞬间动词。

例:My sister has been married for 5 years.(过去分词做表语表示状态,可以延续)

My sister has married. Don't disturb her.(终端动词)

C) 在"this is the first/ second/ third…… time that……"句型里要求用完成时。例:This is the second time that the products of our company have been shown in the International Exhibition.(这是我公司产品第二次参加国际展览会。)D) 句型"It is/ has been……since"所使用的两种时态都正确。

例:It is/ has been 10 years since I last saw him.(从我上次见到他以来已经10年了。)

E) 在"no sooner than"、"hardly/ scarcely ……when"、"before"、"prior to"等句型中,主句要求完成时。

例:I haven't met that professor prior to today.(以前我从未见过那位教授。)4. 现在完成进行时(have been doing):和现在进行时很像

1) 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。)

2) 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。

A. has begun B. had begun C. has been on D. had been on 【答案】 D 【解析】【分析】句意:她说当她到达电影院的时候,电影已经开始五分钟了。根据got 可知,电影开始五分钟属于在过去某时间前已经存在的状态,应该用过去完成时,所以排 除A和C。开始begin,电影已经开始了五分钟是存在的状态,要用延续性的动词,所以要 将瞬间动词begin改为be on,故选D。 【点评】此题考查动词的时态问题以及瞬间动词和延续性动词的区别。 2.Simon ________ the piano for ages when he gave his first concert.

现在完成时练习题及答案

一、时态讲解:现在完成时 (1)构成:现在完成时由助动词have + 过去分词构成,助动词have 有人称和数的变化。第三人称单数用has,其余用have. 现在完成时的否定式直接在助动词后面加上not、疑问式是把助动词提到主语之前。以study 为例,其否定式、疑问式和简单回答形式如下: 1)现在完成时通常表示在说话之前已经完成的动作或存在的状态。说话人强调的是该动作或状态对现在的结果或影响。 My daughter has just gone out. 我女儿刚出去。 I’m sure we’ve met before. 我肯定我们以前见过面。 She has arrived. 她到了。 2)表示持续到现在的动作或状态,往往和包括现在在内的表示一段时间的状语连用,如recently, already, just, lately, fo r…, since…,yet等。如: I haven’t heard from her these days. 这些日子我没有收到她的信。 We haven’t seen you recently. 最近我们没有见到你。 They have been away for two years. 他们离开已经两年了。 She has been with us since Monday. ★注意: a)since和for的区别 since后接时间点,如1993,last term, yesterday, the time I got there for后接一段时间,表示“长达多久”,如ten years, a while, two days等。 Exercise: 用since和for填空 1.

高三英语过去完成时专题训练答案及解析

高三英语过去完成时专题训练答案及解析 一、单项选择过去完成时 1.-----What were you up to when she dropped in? ------I______ for a while and _____ some reading. A.had played ; did B.played; did C.had played :was going to do D.was playing; was going to do 【答案】C 【解析】 考查时态。由第一句可判断出第二句描述的事情发生在过去,for a while是相对于when she dropped in来说的when she dropped in,“我已经玩一会儿了”,因此该用过去完成时态.再看后一个动作,承接前面for a while,仍然在过去,had played for a while之后,因此应用过去将来时,表示过去那个时间将要发生的动作,故选C。 2._______ could be judged from her eyes that she was terribly sorry for what she ________. A.As; had done B.That; did C.As; did D.It; had done 【答案】D 【解析】 本题句意“从她的眼神可以判断,她为她所做的感到非常抱歉”。此句中的that引导的从句是真正的主语,而it作形式主语。她感到抱歉是过去时,而所做的在抱歉之前已发生,故用过去完成时。 3.The wife a big dinner when the husband was aware of their eighth wedding anniversary that day.

I have been working here since 2001. 2. 现在完成时和现在完成进行时都可以表示一段时间内进行的动作.例如: Mr. Smith has taught English for 20 years. Mr. Smith has been teaching English for 20 years 6 现在完成时和现在完成进行时的区别 1)现在完成进行时更强调动作的延续性,它是现在完成时的强调形式。试比较: We've been living here for ten years. We've lived here for ten years.我们在这儿已经住了十年了。
