现在完成时的用法和练习题

一. 用法:

(1)动作发生在过去,强调对现在的影响。

与一般过去时的区别:

强调过去—一般过去式

强调对现在的影响---现在完成时。

试比较:

I have lost my new book. 我把新书丢了。(现在还未找到)

I lost my new book yesterday. 我昨天把新书丢了。(昨天丢的,现在找到与否没说明)

My mother went to Shanghai.

Where is your mother? ---She has gone to Shanghai.

. I didn’t have breakfast.

I haven’t have breakfast yet.

(2)动作发生在过去某个不确定的时间,但对现在有某种影响和结果。常被just、already、yet 等副词修饰。如:

--Have you had lunch yet? --Yes, I have. I've just had it.

你(已经)吃午饭了吗?我刚刚吃过。(现在我不饿了)

(3)现在完成时表示未完成。动作从过去延续到现在,还可能以后继续。通常和带有for和since等表示一段时间的状语。

He has been in the army for ten years.

I have studied English since 1980.

(4)表示说话前发生过一次或多次的动作,现在成为一种经验,一般译为汉语“过”,表示次数:一次once; 二次: twice, 三次:three times…, ever, never等时间状语。

如:I have been to Beijing twice.我去过北京二次。

I have been to Shanghai twice.

She has watched this film three times.

I have never seen more beautiful girl than she.

B.for 与since区别: for +时间段since+ 时间点

They have been to that village several times. 他们去过那个村庄好几次了。

(三).have(has) gone to意为“到某地去了”,表示到了某地或正在去某地的途中。总之,说话时该人不在现场,一般不用第一、第二人称代词作句子的主语。

过去完成时

一.【含义】

过去完成时表示在过去某一时间或动作之前已经发生或完成了的动作。它表示动作发生的时间是“过去的过去”。如:

He asked if you had written to Peter. 他问你是否给Peter写信了。

二.【结构】

①基本形式:had + 过去分词。如:

We had reached the top of the hill before midnight.

在半夜之前我们已登上了山顶。

②否定形式:had + not + 过去分词。如:

They hadn’t finished the work when we got there.

我们到那儿时,他们还没有完成工作。

③一般疑问句形式:had提到句首,回答用Yes, 主语+ had. / No, 主语+ hadn’t.如:

—Had he told you to go there earlier yesterday?

他昨天告诉过你早点儿到那儿吗?

—Yes, he had. (No, he hadn’t.) 是的,他告诉了。(不,他没有。)

④. 被动语态形式:had + been + 过去分词。如:

When I got there, the windows had been broken. 当我到那儿时,窗户已经被打破了。

三.【用法】

①用在主句为一般过去时的宾语从句中。如:

My father asked me if I had finished reading that book. 爸爸问我是否读完那本书了。

②用在“after / before / when + 过去时态从句”或有“by+过去时间”的句子中。如:

Mother had already cooked supper before I returned home.

在我回到家前,妈妈已经把饭做好了。

③和由for或since 引导的、表示一段时间的短语或从句连用。如:

He had worked in that factory for five years before he moved here.

他搬到这儿前已经在那个厂子工作了五年。

<与其他时态间的联系与区别>

1. 与一般过去时:和一般过去时都可指动作发生在过去,但强调动作相对于过去某一时刻已经完成;而一般过去时则强调动作发生在过去某一时间或过去经常性、习惯性动作,需要特别注意的是:当动作附带yesterday、last year等过去时间状语时,应用一般过去时态。请区别:

By the end of last year, I had visited seven different cities.

截止到去年年底,我已经参观过七个不同的城市了。

We learned another English song last month. 上个月我们学了另一首英文歌曲。

2. 与现在完成时:现在完成时表示动作相对于现在已经完成,其标准对照时间点为现在;而表示动作相对于过去某一时刻前已完成,其标准对照时间点为过去。试比较:

I have been there twice. 我去过那儿两次。

I had been there twice before I went to school. 在我上学前,我去过那儿两次。

初中英语动词时态讲解及练习

16种英语时态总结归纳 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。 1. 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。 例:He always helps others. (他总是帮助别人。) 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。 例:When you have finished the report, I will have waited for about 3 hours.(等你完成这份报告的时候,我就已经等了将近3个小时了。) 2. 现在进行时(be doing) 用法:现在正在进行的动作。 3. 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。 例:I bought a new house, but I _________ my old one yet, so at the moment I have two houses. A) didn't sell B) sold C) haven't sold D) would sell 答案是C) haven't sold。 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。 例:Great as Newton was, many of his ideas ___________ today and are being modified by the work of scientists of our time. A) are to challenge C) have been challenged B) may be challenged D) are challenging 全句的意思是:“虽然牛顿是个伟大的人物,但他的许多见解直到今天还在受到挑战,并且被现代科学家的工作所修正。”challenge是及物动词,在本句中应当是被动语态;其动作延续到今天,所以要用现在完成时态。可见答案是C) have been challenged。A) are to challenge和D) are challenging都是主动语态,不可能是答案。B) may be challenged虽然是被动语态,但意思与全句内容不合,所以不对。 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。) 注意事项 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。

初中英语时态讲解练习

初中英语时态综合讲解训练 学习英语时态的意义: 英汉两种语言在时态表达方式上有很大的差异: 如,“他经常帮助我。”“他昨天帮助我了。”和“他一直在帮助我。”这三句话当中,汉语的动词“帮助”没有任何变化,而是用“经常”、“一直”和“昨天”分别表达出时间的区别。 英语就不同,它必须用动词本身的形态变化来完成任务。 He often helps me. 他经常帮助我。 He helped me yesterday. 他昨天帮助我了。 He has been helping me. 他一直在帮助我。 在这几句中,动词help的意义没有变化,但形态变了. 我们初中英语需要掌握多少个时态呢? 一.初中英语常见的八种时态 1 一般现在时 1)经常性或习惯性的动作,常与表示频度的时间状语连用。 时间状语:often ,usually, always, every day/week…, sometimes, at…, on Sunday。 例如:I leave home for school at 7 every morning. 每天早上我七点离开家。 提醒:当第三人称单数作主语时,别忘了动词的变化 He usually goes to school by bike. 2)客观真理,客观存在,科学事实。例如: The earth moves around the sun. 地球绕太阳转动。 Shanghai lies in the east of China. 上海位于中国东部。 3)表示格言或警句。例如: Pride goes before a fall. 骄者必败。 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。 例:Columbus proved that the earth is round. 哥伦布证实了地球是圆的。 2 一般过去时 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, yesterday morning/afternoon/evening, last week/month/year, an hour ago, the other day, in 1982等。 例如:Where did you go just now? 刚才你上哪儿去了? 2)表示在过去一段时间内,经常性或习惯性的动作。 例如:When I was a child, I often played football in the street. 我是个孩子的时候,常在马路上踢足球。 Whenever the Browns went during their visit, they were given a warm welcome.
