一、一般过去时与现在完成时的用法比较。

1.“一般过去时”所关心的是过去之事,与现在无联系,常带有表示过去某个时间的状语;现在完成时所关心的是过去发生的事,对现在产生某种结果,强调过去与现在的联系。一般不与过去具体时间连用。当需要指明过去一个特定的时刻发生的事情时,需要使用一般过去式。

A.I ________(lose) my pen.Can you lend me yours?

B.Why don't you buy one?

A.It _______(fall) into the river only a moment ago when I washed my han ds. Now I've got to fill in a form with a pen.

2.现在完成时与for或since引起的短语连用时,表达从过去开始的动作或状态延续至今,而一般过去时与“for+一段时间”连用时,只指过去的动作或状态在过去延续了多长时间。

We___________(stay) here for three weeks. I think we are going to stay an other two weeks.(说话时人还在)

Great changes _______( take) place in the last ten years

John taught math for twenty years. 表明约翰已经不再教数学了,他可能退休了,换

工作了,或者去世了。

7如果一件事情发生在过去并且延续到说话的这个时刻,就需要使用现在完成时。

They have lived here for a long time.

二、一般过去式与过去完成时的区别。

1.一般现在时表示过去某一时间内发生的动作或存在的状态,而过去完成时则表示

过去某一动作或时间之前发生的动作或存在的状态。一般过去时与现在相比,强调“过去”,而过去完成时则与过去相比,强调“过去的过去”。

我们来比较下列句子:

The meeting _________(start) at six o'clock./ start的动作发生在at six o'clock。

The meeting ___________( start) when we arrived at the hall./ start的动作发生在过去的动作arrived之前。

过去完成时与现在完成时的区别

现在完成时表示的动作发生在过去,以现在的时间为基点,但侧重对现在产生的结果或造成的影响,与现在有关。过去完成时则是一个相对的时态,以过去时间为基点,它所表示的动作不仅发生在过去,更强调“过去的过去”,只有和过去某时或某动作相比较时,才用到它。比较:I have learned 1000 English words so far.到目前为止我已经学会了1000 个

英语单词。I had learned 1000 English words till then.到那时为止我已经学会了1000 个英语单词。

一般过去式,现在完成时区别

1、现在完成时的定义: 现在完成时通常是指过去某一动作对现在的影响或过去某一动作持续到现在(可能要继续下去) 2、现在完成时的构成: 现在完成时是由“助动词have/has+过去分词”构成的 3、现在完成时的用法: (1) 表示从过去到现在曾经经历过或做过的事情 (2) 表示过去发生的动作对现在所产生的影响 (3) 表示从过去某时开始的动作,状态一直持续到现在 一般过去时也译为单纯过去时。 例A:He worked very hard last year. (去年他很用功。) 例B:Mr. Smith bought a new car yesterday. (史密斯先生昨天买了一辆新车。) 例C:They were here only a few minutes ago. (几分钟前他们还在这里。) 一、一般过去时的用法: 解说:一般过去时最明显的现象就是常由表达过去之时间的副词或副词短语来修饰它(如各例句的斜体字部分)。这些常用于修饰一般过去时的副词有:yesterday, yesterday morning (afternoon, evening ), just now (刚才), before (以前) , then (at that time )(当时) , last +时间(如 last week, month, year, Monday, … January, … spring, …, etc. ), that +时间(如 that day, afternoon, summer, …, etc. ), 时间 + ago (如a few minutes ago, two weeks ago , years ago, … etc.) 二、一般过去时的主要语法功能: 1. 表示过去发生的动作或情况, e.g. He returned home very late last night. 他昨晚很晚回家。 He turned off TV at midnight. 他午夜才关了电视。 他常常在午夜后才关电视。He often turns off TV after midnight. 2. 表示过去反复发生的或习惯性的动作,常和never, often, usually等状语连用。 e.g. She often swam/ went swimming last summer. 去年夏天她经常去游泳。 In the past few years, Mary seldom called her grandfather. 过去几年中,玛丽很少给她爷爷打电话。 3. 可用在said, reported等后面的间接引语中,代替一般现在时。 e.g. She said, "I'm tired of his long speech."----She said that she was tired of his long speech. 她说她烦透了他的长篇大论。 The doctor reported, "The patient is very well."----The doctor reported that the patient was very well. 医生说患者情况良好。

一般过去时与现在完成时的用法区别

一般过去时与现在完成时区别专题 一、前言: 初一下学期同学们学习了一般过去时态的相关知识,即将到来的初二上学期英语学习中,现在完成时是重要的学习内容。本文通过对比一般过去时和现在完成时,对现在完成时进行初步讲解,希望使同学们读新学期的学习有所准备。 二、现在完成时 1. 现在完成时的构成 现在完成时是由助动词have (has)+动词的过去分词构成。助动词说明该谓语是属于现在时范围。它和主语的人称、数要保持一致。过去分词是主要的谓语动词,说明句子的意义。 2. 现在完成时的用法 现在完成时表示过去某时发生的行为对主语目前产生的影响。即用过去发生的某个行为来说明现在的某种情况。 We are good friends.(现在的情况) I knew him in 1997.(过去的动作) We have known each other since 1997. (现在完成时把过去的动作和现在联系起来并着眼于现在) (1)表示动作发生在过去某个不确定的时间,但对现在留下了某种影响和结果。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) (2)表示从过去某一时刻开始一直持续到现在的动作或状态。这个动作可能刚停止,可能仍然在进行。常带有for和since等表示一段时间的状语。 如:He has taught here since 1981 他自1981年就在这儿教书。(可能还要继续教) I haven't seen her for four years. 我有四年没见到她了。 (3)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”,常带有twice,ever, never,three times等时间状语。 如:I have been to Beijing twice.我去过北京二次。 3.现在完成时的时间状语 (1)现在完成时属于现在时范围,故不能和过去的时间状语连用。如:yesterday,last Sunday,in1990,three years ago等。但是,在强调动作产生的后果和影响时,可以和一些表示不确定的时间状语连用。 a. 用副词already和yet。already一般用于肯定句中,yet一般用于否定句和疑问句中。 如:We have already finished our homework.我们已完成作业了。 They haven't finished their homework yet.他们还没有完成作业。 b.用ever 和never。多用于否定或疑问句中,表示“曾经”或“从未“等。 如:-Have you ever been to the Great Wall? 你曾经去过长城吗? -I have never been to the Great Wall.我从未去过长城。 c.用表示到说话为止的过去时间状语,如just, before, up to now, the past few years等。 例如:I have seen her before, but I can not remember where. 我以前见过她,但记不起在哪里见过。

现在完成时的用法和过去式.docx

现在完成时的用法和过去式的主要区别: 1. 概念上的区别: —般过去时:表示过去某个时间发生的事、存在的状态或经常发生的动作。说话的侧重点只在于陈述一件过去的事情,不强调对现在”产生的影响。 现在完成时,①表示过去发生并且已经完成的动作对现在造成影响或后果; ②过去某一时间开始并一直持续到现在并且有可能还会持续的动作或状态。 He ViSited Guilin in 1998.他1998年参观过桂林。(只是简单表明在过去某个时间[in 1998]去过 桂林这一事实,除此以外别无其他) Jill has bought a new COmPUter.吉尔买了一台新电脑。(造成的结果是,JiIl现在有了一台新电脑)The pla ne has already arrived 飞机已经抵达了。(说明现在的情况:飞机在这儿。) The Pla ne arrived a quarter of an hour ago. 飞机是一刻钟以前抵达的。(强调动作发生的时间 在过去。) 第一种:对目前造成的影响;过去发生并且已经完成的动作对现在造成影响或后果; HaVe you Seen the film? (A) Did you See the film? (B) [说明]你看过这部电影吗? (A)句强调的是被问者对剧情是否了解; (B)句强调的是看这部电影的动作是否发生过,并不强调是否知道其内容。 第二种:过去某一时间开始并一直持续到现在并且有可能还会持续的动作或状态。 He has lived in Beiji ng for 8 years. (A) He lived in Beiji ng for 8 years. (B) [说明]他在北京住了8年。 (A)句讲的是到目前为止他在北京住了8年,可能还会继续在北京住下去。

过去完成时的标志词

(1)表示在过去某一时刻或动作以前完成了的动作,也可以说过去的时间关于过去的动作。即“过去的过去”。可以用by, before等介词短语或一个时间状语从句来表示,也可以用一个表示过去的动作来表示,还可能通过上下文来表示。 (2)表示由过去的某一时刻开始,一直延续到过去另一时间的动作或状态,常和for, since构成的时间状语连用。 (3)叙述过去发生的事情,在已叙述了过去发生的事情后,反过来追述或补述以前发生的动作时,常使用过去完成时。 (4)在含有定语从句的主从复合句中,如果叙述的是过去的事,先发生的动作常用过去完成时。 (5)过去完成时常常用在told,said,knew,heard,thought等动词后的宾语从句(或间接引语)中,这时从句中的动作发生在主句表示的过去的动作之前。 (6)状语从句:在过去不同时间发生的两个动作中,发生在前,用过去完成时;发生在后,用一般过去时。 注意:如果两个动作紧接着发生,则常常不用过去完成时,特别是在包含before和after的复合句中,因为这时从句的动作和主句的动作发生的先后顺序已经非常明确,这时可以用一般过去时代替过去完成时。 (7)动词think, want, hope, mean, plan, intend等用过去完成时来表示过去未曾实现的想法,希望,打算或意图等。 (8)过去完成时还可用在hardly…when…, no sooner…than…, It was the first (second, etc) time (that)…等固定句型中。 过去完成时-语法判定 1. 由时间状语来判定一般说来,各种时态都有特定的时间状语。与过去完成时连用的时间状语有:( 1 ) by + 过去的时间点。如: I had finished reading the novel by nine o'clock last night. ( 2 ) by the end of + 过去的时间点。如: We had learned over two thousand English words by the end of last term. ( 3 ) before + 过去的时间点。如: They had planted six hundred trees before last Wednesday. 2. 由“过去的过去”来判定。过去完成时表示“过去的过去”,是指过去某一动作之前已经发生或完成的动作,即动作 有先后关系,动作在前的用过去完成时,在后的用一般过去时。这种用法常出现在:( 1 )宾语从句中当宾语从句的主句为一般过去时,且从句的动作先于主句的动作时,从句要用过去完成时。在told, said, knew, heard, thought 等动词后的宾语从句。如: She said that she had seen the film before. ( 2 )状语从句中在时间、条件、原因、方式等状语从句中,主、从句的动作发生有先后关系,动作在前的,要用过去完成时,动作在后的要用一般过去

一般过去时和现在完成时用法区别(详细点)

一般过去时和现在完成时用法区别(详细点) 1) 经常性或习惯性的动作,常与表示频腮度的时间状语连用。时间状语:every…, sometimes, at…, on Sunday I leave home for school at 7 every morning. 2) 客观真理,客观存在,科学事实。 The earth moves around the sun. 不受时间限制的 Shanghai lies in the east of China. 客观存在 表示格言或警句中。 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.. 3) 现在时刻的状态、能力、性格、个性、特征。 I don't want so much. Ann Wang writes good English but does not speak well. 比较:Now I put the sugar in the cup. I am doing my homework now. ※4)由连词if unless before as soon as when once however 等引起的时间(条件、让步)状语从句,需要用一般现在时,表示将来时. 第一句用一般现在时,用于操作演示或指导说明的示范性动作,表示言行的瞬间动作。再如:Now watch me, I switch on the current and stand back. 第二句中的now是进行时的标志,表示正在进行的动作的客观状况,所以后句用一般现在时。 现在完成时用法解析 1.构成 现在完成时是由助动词have(has)+动词的过去分词构成。助动词说明该谓语是属于现在时范围。它和主语的人称、数要保持一致。过去分词是主要的谓语动词,说明句子的意义。 2.用法 (1)表示动作发生在过去某个不确定的时间,但对现在留下了某种影响和结果。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) (2)表示从过去某一时刻开始一直持续到现在的动作或状态。这个动作可能刚停止,可能仍然在进行。常带有for和since等表
