英语语法现在完成时知识点归纳总结

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。

[整理版]现在完成时therebe

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。
