新概念英语语法串讲——现在完成时

现在完成时指的是过去发生并且已经完成的动作对现在造成影响或后果,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。

一、现在完成时的用法

1. 过去某时发生的动作到目前为止这个动作已经完成。如:

1)I have finished my homework. 我做完家庭作业了。(过去某时开始做,到现在已完成)2)He has already come 他已经来了。(过去某时开始离开某地到这来,现在已在这。)2. 表示动作发生在过去并延续到现在,有可能继续延续下去。如:

1)I have studied English for six years. 我已经学了六年英语了。

(六年前开始学英语,一直学到现在, 也可能继续学也可能就此不学了。)2)I have lived in Shenyang since 1990. 我从1990年就在沈阳住。

(从1990年开始住在沈阳一直住到现在,也可能继续住也可能就此为止。)

二、现在完成时的结构

1)肯定式:主语+ have / has + 过去分词

2)否定式: 主语+ have / has + not + 过去分词

3)一般疑问式Have / Has + 主语+ 过去分词

4)特殊疑问式特殊疑问词+have/has+主语+过去分词

三、现在完成时的时间状语

现在完成时常用的时间状语包括“already, yet,ever, etc”。

例如:We have learned about 3000 English words by the end of this term.

到上学期末我们已经学了3000个英语单词。

注意:

1) 当表示一段时间,现在完成时可以用for 或since引导的状语。

例如:I’ve known Li Li for 4 years. 我认识丽丽已经4年了。

I have worked here since 8 years ago. 自从8年前我就在这工作。

2) 当在肯定陈述句中含有already或just 时,在转换成否定句时,要把句中的already 或just

去掉,在句末加上yet.。

例如:I have already seen the film. ------ I haven’t seen the film yet.

He has just come. ------He hasn’t come yet.

注意:for和since的用法。

①for+时段为…时间

②since+过去一个时间点(译为:自从……以来)

③since+时段+ago

④since+从句(过去时)

⑤It is+时段+since+从句(过去时)

四、过去分词变化规则如下:

1 、规则动词:规则动词的过去分词的构成规则与规则动词的过去式的构成规则相同。四点变化规则:

(1)一般动词,在词尾直接加“ ed ”。work---worked---worked ,visit---visited---visited

(2)以“ e ”结尾的动词,只在词尾加“ d ”。live---lived---lived ,

(3)以“辅音字母+ y ”结尾的动词,将"y" 变为"i" ,再加“ ed ”。

study---studied---studied ,cry---cried---cried

(4)重读闭音节结尾,末尾只有一个辅音字母,先双写该辅音字母,再加“ ed ”。

stop---stopped---stopped , drop---dropped--dropped

2 、不规则动词变化需参看不规则动词表逐一熟记。例如; cut- cut- cut,hit-- hit-- hit.

初中英语现在完成时详解

现在完成时 一、现在完成时构成 构成:现在完成时由助动词have + 过去分词构成,助动词have 有人称和数的变化。第三人称单数用has,其余用have. 现在完成时的否定式直接在助动词后面加上not、疑问式是把助动词提到主语之前。以study 为例,其否定式、疑问式和简单回答形式如下: 1、现在完成时通常表示在说话之前已经完成的动作或存在的状态。说话人强调的是该动作或状态对现在的结果或影响。 My daughter has just gone out. 我女儿刚出去。 I’m sure we’ve met before. 我肯定我们以前见过面。 She has arrived. 她到了。 2、表示持续到现在的动作或状态,往往和包括现在在内的表示一段时间的状语连用,如recently, already, just, lately, for…, since…,yet等。如: I haven’t heard from her these days. 这些日子我没有收到她的信。 We haven’t seen you recently. 最近我们没有见到你。 They have been away for two years. 他们离开已经两年了。 She has been with us since Monday.

①for+时段 ②since+过去一个时间点(译为:自从……以来) ③since+时段+ago ④since+从句(过去时) ⑤It is+时段+since+从句(过去时) Mary has been ill?for three days. I have lived here?since 1998. 注意: since和for的区别 since后接时间点,如1993,last term, yesterday, the time I got there for后接一段时间,表示“长达多久”,如ten years, a while, two days等。3、表示短暂意义的动词如arrive, leave, borrow, buy, begin, start, die等,在完成时当中不能和表示一段时间的状语连用,因为它们表示的动作不可能持续。因此,不能说: He has come here for 2 weeks. × The old man has died for 4 months. × They have left only for 5 minutes. × 4、has gone (to),has been (to), has been (in)?的区别 Have/Has gone(to) :去了(现在不在说话现场,可能在路上和已经到) Where is your father?He has gone to Shanghai. Have/Has been (to) :去过(已不在去过的地方) My father has been to Shanghai. Have/has been in:呆了多久(还在所呆的地方) My father has been in Shanghai?for two months. /since two months ago. 5、现在完成时不能和表示过去的时间状语连用,如yesterday, last year, in 1976, two days ago, just now, when I came in,但可以和already, yet, sometimes, always, often, before, lately, recently, once, twice, ever, never等连用。不能与when连用。

人教版英语英语现在完成时用法总结含答案推荐精选

人教版英语英语现在完成时用法总结含答案推荐精选 一、初中英语现在完成时 1.—Where is Catherine? I haven't seen her for days. —She Wuhan. She'll be back next week. A. has gone to B. has been to C. have gone to D. have been to 【答案】 A 【解析】【分析】句意:——Catherine在哪里?我好几天没见她。——她已经去武汉了。她将下周回来。主语是she,所以用has,排除C、D。A.已经去了某地,在去的路上,还没有回来;B.已经去过某地,表示去了某地,并且回来了。根据She'll be back next week.她下周回来可知现在还没有回来,故选A。 【点评】考查短语辨析,注意平时识记其区别,理解句意。 2.Mike used to be a top student, but he behind since he lost himself in computer games. A. fell B. has fallen C. was D. has been 【答案】 D 【解析】【分析】句意为“Mike过去是尖子生,但自从迷上电子游戏以来成绩落后了”。由since可知but后的主句用现在完成时,瞬间动词fall不能和since引导的时间状语从句连用,故用延续性动词be。故选D。 【点评】本题考查现在完成时中非延续性动词和延续性动词的转换。 3.The Greens many places of interest since two years ago. A. has visited B. have visited C. visited D. will visit 【答案】 B 【解析】【分析】句意:自两年前开始,格林一家参观了许多名胜。since引出的时间状语从句,强调主句谓语从过去某时一直延续到现在,主句用现在完成时态,the Greens格林一家,表示复数含义,作主语,谓语用复数形式。故选B。 4.—Your new bike is so nice! When did you buy it? —In July. I _____it for two weeks. A. had B. have had C. have bought D. bought 【答案】 B 【解析】【分析】句意:——你的新自行车那么好看。你什么时候买的。——七月份,我买了两周了。根据for two weeks,可知句子时态为现在完成时,而且谓语动词必须是延续性的。因此排除AD,buy是结束性动词,不能够延续,应此排除,故答案是B。
