初中英语中考复习：现在完成时的解题技巧

一、基本概念

现在完成时态表示过去发生的动作对现在的影响或有无某方面的经历。

时态构成：have/has + 动词过去分词

现在完成时态是很难掌握的一种时态，因为它并不是表示发生在某一时间的事情，而是既涉及过去，又联系现在的一种时态。 比较：I live in Shanghai. 我住在上海。（一般现在时）

I moved to Shanghai ten years ago. 十年前我搬到上海住了。（一般过去时）

I have lived in Shanghai for ten years. 我在上海住了十年了。（现在完成时）

二、用法详解

现在完成时的构成

现在完成时由“have / has+过去分词”构成。

其中的have / has 为助动词，构成疑问句时，可将其提前；构成否定句时，可直接在其后加not。

过去分词的构成

①一般情况→词尾+ed

动词原形 过去式和过去分词 Walk行走 walked Work工作 worked Help帮助 helped ②以不发音字母e结尾→词尾+d

动词原形 过去式和过去分词 Decide决定 decided Hope希望 hoped Like喜欢 liked ③以“辅音字母+y”结尾→变y为i，再加-ed

动词原形 过去式和过去分词 Carry搬运 carried Hurry快 hurried Fly飞翔 flied ④以重读闭音节结尾，且末尾只有一个

辅音字母→双写词尾+ed

动词原形 过去式和过去分词 Stop停止 stopped Nod点头 nodded Plan计划 planned

注意：上面介绍的都是过去式和过去分词的规则变化，也就是“动词原形+ed”.实际上还有许多动词的过去式和过去分词的变化是不规则的。如：

（1） 动词原形、过去式、过去分词形式都相同： cut→cut, cut(切割)

（2） 过去式、过去分词形式都相同： bring→brought, brought(带来)

（3） 动词原形、过去式、过去分词形式都不相同： go→went, gone(去)

这些规则的变化需要逐个记忆。更多不规则动词的变化，可以查看书后附录。

典型例题 写出下列动词的过去式和过去分词形式。 动词原形 过去式 过去分词

do did done drop go begin cut move fry give smell win run 答案：

现在完成时的用法

表影响：表示过去发生或已经完成的某一动作对现在造成的影响和结果，可以和already, yet, just等连用。

1) I have already posted the photos. 我已经把照片寄了。（照片不在我这里了）

2) ---have you had your lunch yet? 你吃午饭了吗？

---Yes, I have just had it. 是的，我吃了，我刚刚吃过。（现在不饿了） 完成句子：

她刚参加一个晚会回来 She from an evening party.

表继续：表示过去已经开始，持续到现在，还可能继续下去的动作或状态，可以和表示从过去某一时刻延续到现在的一段时间的状语连用。如：this morning, these days, in the last (past)…, since, for a long time 等。

1)They have lived here since 1989. 自从1989年以来，他们就住在这里。

现在完成时与一般过去时的区别

现在完成时与一般过去时都表示过去的动作，但现在完成时强调这一动作与现在的关系，如对现在产生的影响、生成的结果等等，而一般过去时只表示在过去的时间内发生的动作或存在的状态，强调动作，前者强调影响。

1) A: Have you seen the film? 你看过这部电影吗？ B: Did you see the film? 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。

2)A: She has watered the flowers. 她已经浇了花。（不需要再浇了） B:She watered the flowers yesterday. 她昨天浇的花。

表示过去的时间状语如： yesterday, last week , two years ago ,just now ,in 2002 等，以及when为首的疑问句与一般过去时连用，而不与现在完成时连用。

1) Tom has written a letter to his parents last night. （错） Tom wrote a letter to his parents last night. （对） 2) ---have you ever been to the great wall? ---Yes, I have.

---When did you go there? ---Last week.

使用现在完成时的几个问题（非常重要，常考） have been to, have gone to和have been in

1) have been to 表示“过去曾去过某地”，说话时已从该地回来或去了其它地方，总之，现在已不在该地。

2) have gone to 表示“以去了某地”，说话时不在说话地点或在去该地的途中，或已到了该地。总之，现在还未回来。

3) have been in 表示“已在该地（待了多久）”。表示“已在小地方多久”，需用at, 而后面跟副词时只用have been，不用任何介词。 Xiao Li have been to Beijing. 小李去过北京。 Xiao Li have gone to Beijing. 小李去了北京。

Xiao Li have been in Beijing for three years. 小李在北京待了三年了。

典型例题 ( ) 1 My father isn't here now. He ___Shanghai. He ___ there twice. A. has gone; has been B. has gone to; has been to C. has been to; has gone D. has gone to; has been ( ) 2 -Hi! Bruce. I haven’t seen you for three weeks.

答案： 1-5 D C D B D

since的用法

1) since +过去一个时间点 (如具体的年、月、日期、钟点、1980, last month, half past six)。 I have been here since 1989.

My aunt has worked in a clinic since 1949. 2) since +一段时间+ ago

I have been here since five months ago. 比较since和for

Since 用来说明动作起始时间，for用来说明动作延续时间长度。 I have lived here since I was born.

Some new oilfields have been opened up since 1976. I have lived here for more than twenty years. I have not heard from my uncle for a long time. I have worked here for many years.

He has lived in Beijing for 8 years.

典型例题 把括号中错误或不恰当的答案划掉。

例：（Have, Did）you (watered, water) the flowers yet? 你浇花了吗？ 1. The Browns (lived, have lived) in Beijing since 1997. 2. (Have, Do) you (seen, see) Julia recently? 3. ---Would you like some more soup? ---No, thanks. I (have had, had) enough.

4. Wait a minute. They (haven’t arrived, don’t arrive) yet. 5. Is this the first time you (have cooked, cook) spaghetti? 答案：

1. lived（布朗一家自从1997年就住在北京。） 2. Do; see（你最近看到茱莉亚了吗？）

3. had（你想再要点汤吗？不，谢谢，我已经够了。） 4. don’t arrive（等一会，他们还没到。） 5. cook（这是你第一次做意大利面吗？）

现在完成时态中，当句中含有一段时间状语时，谓语动词短暂变延续！

1. 现在完成时中有瞬间动词和延续性动词的区分：

[说明] “终止”、“延续”要转换：英语中的动词从词义上可以分为延续

性和非延续性（瞬间动词）两种，在现在完成时态中一定要注意动词这一特性，当句中含有一段时间状语时，应将这类瞬间动词转换为延续性动词。

瞬间动词：come, go, leave, start, die, finish, become, die等。 延续性动词：live, teach, learn, work, study, know.

例如： The film has begun. → The film has been on for an hour. He has gone . → He has been away for ten minutes.

2、初中阶段常见的瞬间动词对应的延续性动词总结：

leave --- be away, borrow --- keep, buy --- have,

begin/start --- be on, die --- be dead, finish --- be over,

fall ill --- be ill, get up---be

up, become --- be,

catch a cold --- have a cold, go there --- be there,

come back --- be back, put on→ wear；

go out ---be out，

get to/ arrive/reach --- be (in) open(v.)---be open(adj.),

join --- be in+组织机构/ be a member of+组织机构
