英语语法现在完成时知识点归纳总结现在完成时是英语中常用的一种时态,它描述的是过去发生的动作或经历对现在产生的影响或结果。
在学习现在完成时时,有一些重要的知识点需要掌握。
本文将对现在完成时的构成、用法以及一些相关的注意事项进行总结。
一、构成现在完成时由助动词have/has和动词的过去分词构成。
具体构成如下:1. 肯定句:主语 + have/has + 过去分词 + 其他.例如:- I have finished my homework.- He has bought a new car.2. 否定句:主语 + have/has + not + 过去分词 + 其他.例如:- I have not seen him this week.- She has not visited her grandparents yet.3. 疑问句:Have/Has + 主语 + 过去分词 + 其他?例如:- Have you ever been to Paris?- Has he finished his work yet?二、用法1. 表示过去某个时间点开始的动作一直持续到现在,强调对现在的影响或结果。
例如:- I have lived in this city for three years. (到现在为止)- She has studied English since she was a child. (一直到现在)2. 表示过去发生的动作对现在造成的经历或影响。
例如:- I have lost my keys. (我丢了钥匙,现在找不到)- They have seen that movie. (他们看过那部电影,对现在的观影经历有影响)3. 表示过去已完成的动作,常和表示过去的时间状语连用,指的是从过去某一时刻到现在的时间内完成的动作。
例如:- She has already finished her homework. (她已经完成了作业)- They have just arrived at the airport. (他们刚到达机场)三、注意事项1. 现在完成时常与表示过去的时间状语连用,如already, yet, just, for, since等。
现在完成时现在完成时由“have/has+过去分词”构成,主要有两个含义:①表示动作发生在过去,但与现在的情况有联系,有时无时间状语,有时和一些表示不确定的过去时间状语连用,如:many times,just,yet,ever,never,already,before,so far, by now等连用。
②表示从过去某一时间开始一直延续到现在并还可能继续延续下去的动作,用于延续性动词,且句中常带有表示一段时间的时间状语,如:since + 时间点/从句,for two months, so far等。
二、1)现在完成时和一般过去时都能表示过去发生过的动作,但现在完成时表示过去动作对现在的影响,并且表示这一动作已完成或还可能继续下去;2)而一般过去时与现在的情况没有联系,仅表示过去的动作,且这一动作到说话时已终止。
因此现在完成时不能与表示明确的过去时间如:in1949,yesterday,last week等的状语连用,并且用when或where对这些时间和地点状语提问时,一般只用一般过去时。
在“it is first/second...time that...。
”或在“it/this/that is the +最高级+名词+that...。
”结构中,that从句中的动词常用现在完成时;在“it + be...+since从句”这一结构中,be可用一般现在时或现在完成时,since从句一般用过去时。
have/has/had +been +动词的现在进行时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, 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。
一般过去时与现在完成时比较练习题(整理版) 哎呀,这可真是个难题啊!让我想想怎么才能搞定这个题目呢?我们得明确一般过去时和现在完成时的区别。
一般过去时是描述过去发生的事情,而现在完成时则是强调从过去到现在的一个持续性动作或状态。
好了,现在让我们开始吧!1. 一般过去时与现在完成时比较练习题(整理版)我们来看看第一道题目:题目:我昨天去了公园。
(一般过去时)我昨天去了公园,然后我在公园里玩了一整天。
(现在完成时)哎呀,这道题目真是太简单了!昨天我去公园,然后一直在公园里玩,一直到现在为止都还在玩呢!这个过程一直持续到现在,所以要用现在完成时来表达。
接下来是第二道题目:题目:我上个月买了一辆新车。
(一般过去时)我上个月买了一辆新车,结果这个月就坏了。
(现在完成时)这道题目有点难哦!我上个月买了一辆新车,结果这个月就坏了。
这个过程是从上个月开始一直持续到现在的,所以要用现在完成时来表达。
不过,这个月坏了也没关系啦,反正现在已经修好了嘛!第三道题目:题目:我去年学过英语。
(一般过去时)我去年学过英语,但是我现在还不太会说。
(现在完成时)这道题目也很简单啊!我去年学过英语,但是现在还是不太会说。
这个过程是从去年开始一直持续到现在的,所以要用现在完成时来表达。
不过没关系啦,反正我现在正在努力学习嘛!第四道题目:题目:我小时候喜欢吃巧克力。
(一般过去时)我小时候喜欢吃巧克力,现在还是很喜欢。
(现在完成时)这道题目也很简单啊!我小时候喜欢吃巧克力,现在还是很喜欢。
这个过程是从小时候开始一直持续到现在的,所以要用现在完成时来表达。
不过没关系啦,反正我现在还是很喜欢吃巧克力嘛!第五道题目:题目:我上学的时候经常迟到。
(一般过去时)我上学的时候经常迟到,但是现在已经改正了。
(现在完成时)这道题目也很简单啊!我上学的时候经常迟到,但是现在已经改正了。
这个过程是从上学的时候开始一直持续到现在的,所以要用现在完成时来表达。
现在完成时(1):基础用法现在完成时(I)现在完成时表示从过去持续到现在的动作或状态,或已完成但对现在有一定影响的活动。

现在完成时讲解一、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)二、用法1)现在完成时的"完成用法"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.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。
)I have spent all of my money.(含义是:现在我没有钱花了.)Jane has laid the table.(含义是:现在桌子已经摆好了.)2)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。
这里的动词要用持续性动词。
常与for (+时间段),since(+时间点)连用.Mary has been ill for three days.Mary has been ill since three days ago.注意:1.现在完成时不能单独与准确时间连用,(如表示过去的时间状语)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(肯定), yet(否定,疑问), just, before, recently, still, latel y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ever, never, twice, several times等:Have you ever been to BeijingI have never heard Bunny say anything against her.I have used this pen only three times.

现在完成时——讲解部分现在完成时的构成:助动词have(has)+ 过去分词1.表示过去发生或完成的某一动作对现在造成的影响或结果。
例如:I have just cleaned my clothes. 我刚洗过衣服。
(“洗衣服”是发生在过去的动作,对现在造成的结果是“衣服干净了”)现在完成时常用的时间状语有:already (”已经” 用于肯定句的中间和末尾处)never (“从不” 用于中间处) ever (”曾经” 用于疑问句和肯定句的中间处)just (“刚刚” 用于中间处) yet (“已经” 用于疑问句的末尾处/ “还” 用于否定句的末尾处)或不加任何的时间状语,但不能和表示过去的时间状语连用.1. 现在完成时的"完成用法"A、定义现在完成时的"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。
)B、特点现在完成时"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 beforer ecently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"3.A、定义现在完成时的"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。
