琢磨现在完成时Microsoft Word 文档

琢磨现在完成时Microsoft Word 文档

琢磨现在完成时为了应对高考,我们对现在完成时的理解就不能停留在表面。

首先,我们从“现在完成时”的概念上看,它分为“现在”和“完成”两层含义。

其结构“have / has + 过去分词”也充分体现了这一点。

“have / has”是助动词,形式为动词的现在式,表现在,“done”,过去分词表完成。

下面两组句子能充分说明“现在完成时属于现在”这一观念。

We have (got) to stay up late tonight . He has (got ) a bad cold.如果不看got,这两个句子就是一般现在时。

但这两种时态表达了基本相同的意思。

It’s at least forty days since my father- in-law smoked.It has been at least forty days since my father- in-law smoked.这两个句子,时态虽不一致,但表达的意思完全一致:“我岳父戒烟至少四十天了。

”现在,我们来具体阐释掌握现在完成时应注意的内容。

1.现在完成时的定义及常用的时间状语:现在完成时既可表示过去发生的动作对现在所造成的结果或影响。

此时通常连用的时间状语有already, yet, just, ever, never, before。

I’ve never heard of that before. He hasn’t seen a plane yet.也可表示动作从过去某时间开始,一直持续到现在,并且还有可能持续下去(此时通常连用的时间状语有:①today, this morning/month / week / year, these days, by now, until now, till now,up to now ,so far(包括现在在内的时间状语)②recently / lately(也可用于过去时)③ in/over/during the past/last few + 时间段(in the past只用于过去时)④since 1997/since his arrival/since several hours ago(since作介词)Since,..../...,since,..../.....,since./...ever since./since then (since作副词,均译为“自那以后”)since he arrived here(since作连词。

(word完整版)初中英语语法-现在完成时讲解以及练习题讲义

(word完整版)初中英语语法-现在完成时讲解以及练习题讲义现在完成时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have(has)表明事情发生于现在。

它和主语的人称、数要保持一致。

过去分词在句子中做谓语,说明句子的含义。

2.用法(1)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)(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 have'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。
