英语语法现在完成时讲解

第六讲现在完成时

1.概念：

1）、表示动作或状态在过去已经开始, 持续到现在, 也许还要持续下去,常和for, since, 连用, 表示持续的动作或状态多为延续性动词.

eg: We have lived here since 2000.

自从2000年以来我们一直住在这里. ( 说明一直住在这里, 也许还会住下去. )

She has worked in Nanning for five years.

She has been ill for a week.

2）表示过去发生的或已经完成的某一动作对现在造成的影响或结果.

eg: I have lost my pen. 我把钢笔弄丢了. ( 过去某时丢的, 现在还没有找到)

I have already watched the TV play. 我已经看过这部电视剧了.

--- Have you had your lunch yet ? 你吃过午饭了吗?

--- Yes, I have just had it. 是的, 我刚吃过. ( 说明现在饱了)

2. 结构: 主语+ have / has + done + …

3. 句型: ⑴肯定句: ①主语+ have / has + done + …

eg：She has been to Shanghai. 她去过上海.

I have finished doing my homework. 我已经完成我的作业了.

⑵否定句: ①主语+ have / has + not +done + …

eg：I haven’t seen this film. 我没有看过这部电影.

eg：She hasn’t finished doing his homework. 她还没有完成她的作业.

⑶一般疑问句：① Have / Has + 主语+ done + …

eg: Have you seen this film ? Yes, I have. / No, I haven’t .

你看过这部电影吗? 是的, 看过. / 不, 没有.

eg：Has she finished do ing his homework ? Yes, she has . / No, she hasn’t.

她完成她的作业了吗? 是的, 完成了. / 不, 没有.

⑷特殊疑问句：①特殊疑问词+ have / has + 主语+ done + …

eg: When has you seen this film ? 你什么时候看的这部电影?

eg: Who has finished doing his homework ? 谁完成了作业?

4. 时间状语：典型的表时间的词与现在完成时连用，这些词有：

for 、since、already、yet、ever、never、recently、just、before、so far、by now、…

等连用.

注意: for+一段时间since+过去的某一个时间点

I have lived in Nanning for ten years.

I have lived in Nanning since ten years ago/ 2002.

I haven’t eaten anything for ten hours.

I ha haven’t eaten anything since 6am.

already :用于肯定句, 可放在助动词之后、过去分词之前，也可放在句末.

I have already finished my homework.

yet: 用在疑问句中意为”已经”, 用在否定句中表示”还”, 常放在句末.

Have you finished your homework yet?

I haven’t finished my homework yet.

ever: 曾经用于疑问句中：

Have you ever been to Beijing?

Have you ever been to Shanghai ? 你去过上海吗?

never: 未曾从未

I have never traveled by plane before. 我以前从来没有乘飞机旅行过.

recently：最近用于肯定否定疑问句中

I have been busy recently.

We have not seen Tom recently.

Have they been here recently.

eg: I have just seen Tom.

I haven’t heard of it before. 我以前从来没有听说过这件事.

They have planted 2000 trees so far.

The child has learned 100 English words by now.

5. 当与一段时间连用时, 经常用for 加一段时间, 这时候谓语动词一定要用延续性的.

非延续性动词----延续性动词

改错：They have got married for ten years. I have borrowed this book for a week.

get married--- be married borrow --- keep

come ---- be here go --- be away / off buy --- have

start / begin --- be on leave --- be away die --- be dead

arrive---be in/at join---be in /be a member of stop---be over

return----be back open/close---be closed/open

eg: He came here three days ago. 他三天前来的这. (一般过去时)

He has been here for three days. 他来这已经三天了.

(现在完成时与一段时间连用, 非延续性动词变延续性动词. )

He went to Dalian last week. 他上周去的大连. ( 一般过去时)

He has been away for a week. 他已经离开有一周了. ( 现在完成时)

I bought the book last month. 我去年买的这本书. ( 一般过去时)

I have had the book for a month. 我保管这本书有一周了. ( 现在完成时)

The football match started an hour ago.

The football match has been on for an hour.

6. 词义辨析

have been to 曾经去过某地，说话时已经从某地回来或者已从该地去了其他的地方。

eg: I have been to Canada. 我去过加加拿大.

have gone to 已经去了某地，书说话时还未回来。

eg: He has gone to Dalian. 他去了大连.

have been in 已在某地待了多久，大地方用in 小地方用at, 后面是副词则不用介词The Greens have been in China for two years.

7. 现在完成时与一般过去时的区别：

1）、侧重点不用，现在完成时是与现在有关的时态，侧重于过去的动作对现在造成影响，

而一般过去时是一种过去的时态，侧重于表示过去的动作，与现在无关。

I went the zoo yesterday. 尽说昨天去了动物园，与现在无关。

Li lei has read the book. 说明李雷理解那本书。

2）、与现在完成时连用的时间状语有：for 、since、already、yet、ever、never、recently、just、before、so far、by now、而一般过去时则常与yesterday, ago last, in 20000, just now, 连用。

英语语法-现在完成时用法及习题

目录 1现在完成时的构成 (2) 2现在完成时的用法 (5) 3 使用现在完成时需注意事项 (7) 4过去完成时与现在完成时的比较 (12) 练习题 (13) 答案 (16)

现在完成时对于我们来讲是所有时态中最难掌握的一种。因为它并不是表示发生于某一时间的事情，而是既涉及过去，又联系现在的一种时态。请参见下列三个例句：例：1.I live in Beijing. 我住在北京。 2.I lived in Beijing. 我住过北京。（我在北京住过。） 3.I have lived in Beijing. 我一直住在北京。例1.的live是一般现在式，表示“我现在住在北京”这一事实。例2.的lived是过去式。这句只是表示在过去的某一时期我在北京住过，至于现在住不住在北京则不清楚。例3.的have lived是现在完成时，表示我在过去的某一时间开始住在北京，现在也住在北京。表示从过去到现在的一种继续状态。 1现在完成时的构成现在完成时的形式是“have （has）+过去分词”，表示继续、完了、结果和经验等四种意思。现在完成时的否定句是在have（has）的后面加上not，疑问句是将have（has）置于主语之前。 1现在完成时的肯定句句型：

We have lived in Beijing. 我们一直住在北京。 He has lived in Beijing. 他一直住在北京。过去分词的三种用法过去分词有下列三种用法（过去分词的构成详见第六章）：1.构成现在（过去）完成时 have（has）+过去分词～ I have written the letter. 我写完这封信了。 2.被动语态：参见第十三章 be + 过去分词～ He was looked after.他受到照顾。 3.用于形容词 This is a broken chair. 这是一张坏的椅子。 2现在完成时的否定句句型：主语+have（has）+not +过去分词～. I have not seen the movie yet.

英语现在完成时语法详细讲解与配套习题一、现在完成时用来表示之前已发生或完成的动作或状态，但它的影响现在还存在；也可表示持续到现在的动作或状态。其构成： have (has) +过去分词。规则变化的过去分词与过去式的变化一样，在动词词尾加ed; 不规则变化的过去分词见不规则动词表，需要同学记忆。现以see the film为例将现在完成时的肯定句，否定句和疑问句列表如下：肯定句：I/You/We/They have seen the film. He/She /It has seen the film. 否定句：I/You/We/They have not/ haven’t seen the film. He/ She/It has not/hasn’t seen the film. 疑问句：Have I/you/they seen the film Yes, you/ we/I/they have. No, you/ we/I/they haven’t. Has he/she/it seen the film Yes, he/ she/ it has. No, he/ s he/ it hasn’t. 二、用法：现在完成时既涉及过去，又联系现在。标志词词义用法位置 already已经肯定句句中或句末 ever曾经疑问句、肯定句句中 never从未，从来不陈述句，不和not 连用句中 (ever)since自从肯定、疑问、否定句中 for后接一段时间肯定、疑问、否定句中 just刚刚，正好肯定句句中 yet还疑问句、否定句末 recently最近肯定、否定、疑问句句末 once, twice, a few times几次肯定、疑问句末 during/over /in 在过去的一段时间里肯定、疑问、否定句末 the past/last + 一段时间 It’s the first time I …这是我第一次…肯定句前

现在完成时的构成英语语法大全

现在完成时的构成一）肯定式主语＋助动词have ／has ＋过去分词＋其它说明：这里的have ／has是助动词，没有什么具体意义。当主语是第三人称单数时助动词用has，其余人称一律用have。has，have的缩略式分别为's或've。规则动词过去分词的构成与过去式的构成方式一样，不规则动词可参看不规则动词表。实例： 1）I've just copied all the new words ．我刚抄写了所有的生词。(表示不要再抄了) 2）She has lost her books ．她丢失了她的书。（表示到目前为止还没有找到） (如果用过去时：She lost her books . 则强调书是过去丢的这一动作，而不知现在有没有找到) 3）We've just cleaned the classroom ．我们刚好打扫了教室。（表明现在教室是干净的）二）否定式主语＋助动词have ／has＋not＋过去分词＋其它说明：现在完成时构成否定句时，只需在助动词have ／has后面加not就行。have not，has not的缩略式分别为haven't ，hasn't。另外，肯定句中有some，already时，改为否定时要分别改成any，yet。实例： 1）I haven't finished my homework yet．我还没有完成我的作业。 2）She hasn't travelled on a train ．她没有坐火车旅行过。 3）We have never spoken to a foreigner．我们从来没有和外国人说过话。注：有时not可以用never代替，表示“从来没有”的意思。又如： 4）I have never seen him before．以前我从来没有见过他。三）一般疑问式助动词Have ／Has ＋主语＋过去分词＋其它？说明：把陈述句中的have或has放到句首，句末打问号，同时把句中的some ，already改为any ，ye t就构成了一般疑问句。肯定回答用“Yes ，主语＋have／has．否定回答用“No，主语＋haven't／hasn't．”有时也可以用“No，not yet．／No ，never．／No，not even once．”等。实例：

英语语法—现在进行时(基本)

现在进行时现在进行时表示动作发生的时间是“现在”，动作目前的状态是“正在进行中”。所谓“正在进行中”，是指在谈到这件事的时候，这个动作还在进行中。至于它是什么时候开始的，什么时候会停下来，不是我们关心的。所以“正在进行时”的事件，可能发生几年了，也可能只有几分钟。仍在进行中这是“正在进行时”的关键所在。它是一件持续进行的事情。定义：现在进行时的定义：现在进行时表示现在或当前一段时间正在进行的动作。可以表示有计划的未来，也就是用现在进行时表示将来。构成：现在进行时的构成是:主语+be+v.ing〔现在分词〕形式第一人称单数 I+am+doing+Sth. 第一人称复数 We+are+doing +Sth. 第二人称单(复)数You+are+doing+Sth. 第三人称单数He（She，it）+is+doing+Sth. 第三人称复数They+are+doing +Sth. 肯定句:主语+be（is/am/are）+现在分词否定句：主语+be（is/am/are）+not+现在分词一般疑问句:be（is/am/are）+主语+现在分词特殊疑问句：特殊疑问词+相应be动词+主语+现在分词+Sth

变化规则： 1.直接+ ing(例：sleep+ing sleeping) 2.去掉不发音的e+ing(例：bite-e+ing biting) 3.重读闭音节，且末尾只有1个辅音字母，双写辅音字母+ing (例：sit+t+ing sitting) 4.特殊变化：die-dying,lie-lying，tie-tying 5.不规则变化句型构成：现在进行时助动词be 动词的现在分词（ing形式）。 be的变化在现在时中，be 要根据人称代词和名词的单复数不同，而分别使用am/is/are，即：I am/he/she/it 包括单数名词和不可数名词用is,you/we/they 包括复数名词用are. 注意：be 动词在现在时里算作“助动词”，翻译正在进行时的时候，be不能解释为“是”，否则不通顺。它只是和现在分词一起构成“进行时”。现在分词加ing的规则现在分词是在动词后加上ing 构成。如:starting,working, coming, sitting 等都是现在分词。现在分词的变化规则是固定的，大家用心记一下就可以了。

英语语法完成时篇

完成时篇（一）——现在完成时 [提问] 请问在句子“Working in London has been the best decision I have made so far. （Experiencing English Integrated Book1 Page71）”中，为什么时间状语是完成时的情况下，主句仍然可以使用现在完成时呢？答：完成时态通常表示已完成或已经开始从事的动作，它可以分为现在完成时、过去完成时、将来完成时以及完成进行时。根据定义我们可以了解到，除了表示到现在为止动作已经完成或已经开始以外，还有多种情况可以用现在完成时来表达。一、动作从过去某个时间开始发生，延续到现在，并且说话前已经完成。例如：The mission has been carried out well.任务已经很好地完成了。 Those girls have eaten two big cakes.女孩们已经吃了两个蛋糕了。二、某个动作或状态发生在过去，持续并影响现在，有可能会继续保持下去。例如：My brother has been abroad for several years.我哥哥已经出国好几年了。 It has rained all morning.雨下了一个早晨。 Up to now, parents have accepted the pop music youths prefer to.现在，家长们已经接受了年轻人喜欢的流行音乐。 I have known him since the summer in 2001.自2001年的那个夏天，我就认识他了。三、动作发生在现在之前的某个时间，可能是多次动作的集合，也表示习惯性的动作或状态。例如：Xiao Qin has come over here three times in the daytime.白天小覃已经来过三次了。 Which countries have you traveled recently?最近你都去过那些国家？ How many papers have you read today? 你今天看了几篇论文？四、动作过去曾发生过一次或多次，也可能是一种经历。例如：Students are very pride that the president has once visited their school. 学生们为总统曾访问过他们学校而骄傲。 Accidents like this have happened more than 20 times these years.这几年此类事故发生不下20起。在现在完成时态的句子中，常伴随的时间状语有：already，yet，ever，never，just，before，lately，recently，till/until，always，now，since，today; in past years，all morning，all one’s life，up to now，these days，this week/month/year，for a long time。现在完成时中有几点语法点要注意的： 1）for引出的时间状语只能修饰表示延续性动作的动词。不能用来修饰表示瞬间、短暂动作或位置转移的动词。如John has come to China for three years，此句错误，come这个动作是短暂性动词，不可能持续发生，因此可改为John has been in China for three years，约翰已经爱中国生活了3年。短暂性动词有appear, begin，borrow，buy，come，close，die，fall，find，finish，join，kill，leave，lend，lose，see，start，stop。 2）在表示时间或条件的状语从句可以用现在完成时表示将来完成的动作。例如：He will not quit my job until his parents have permitted.父母允许后他才会辞职。 I will arrive at 6 o’clock if the car h as been prepared then.如果到时车准备好了，我能在6 点到达。 3）It is the first/second time that…这个结构中，that从句要用现在完成时。例如：It is the first time that I have heard of his deeds.这是我第一次听说他的事迹。

新概念第二册语法解析及练习：现在完成时

现在完成时： 1．构成：have / has + 过去分词 2．功能：（1）表示过去所发生的动作对现在的影响或产生的结果。常与yet, just, before, recently, lately（最近）, ever, never等表时间的副词搭配使用。 ?. He hasn't seen her lately. ?. I haven't finished the book yet. （2）表示一个从过去某个时间开始，延续到现在并可能持续下去的动作，常与表示一段时间的时间状语连用。如：so far（迄今为止）, up till now（直到现在）, since, for a long time （很长时间）, up to present（直到现在）, in the past / in the last few years（在过去的几年里）, these days（目前）…… ?. He has worked here for 15 years. ?. I have studied English since I came here. ?. The foreigner has been away from China for a long time. ?. So far, I haven't received a single letter from my brother. （3）某些非延续性动词（即：动作开始便终止的动词），在现在完成时中不能与表示一段时间状语搭配。黄金要点：I．常见的非延续动词：die, arrive（到达）, join（加入）, leave（离开）, go, refuse （拒绝）, fail（失败）, finish, buy, marry, divorce（离婚）, awake（醒）, buy, borrow, lend ... II．这类动词并非不能用现在完成时，而是不能接常由for引导的时间状语。 III．但若是用在否定句中，非延续动词的现在完成时可以与表示一段时间的状语连用。?. She has gone away for a month.（误）?. She has been away for a month （正） ?. The man has died for two years.（误）?. The man has been dead for two years.（正）?. How long have you bought the book?（误）?. How long have you got the book.（正）

现在完成时语法

（Present Perfect）。第一部分现在完成时表示过去发生或已经完成的动作对现在造成的影响或结果,也可表示过去已经开始,一直延续到现在的动作或状态。学习现在完成时,先从结构和句式开始: 构成:主语 + have/has + 过去分词 + 其他。(当主语是第三人称单数时用has,其余人称用have。过去分词:规则动词的过去分词构成与动词过去式相同;不规则动词需要特殊记忆。) 否定式:主语+ haven't/hasn't + 过去分词+ 其他。疑问式: Have /Has + 主语+ 过去分词+ 其他? 简略答语: Yes, 主语+ have/has.(肯定) No, 主语+ haven't/hasn't.(否定) 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. 第二部分现在完成时的含义之一是过去完成的动作对现在仍有影响,用以下四大标志词可以表达这种含义: * 以already, just和yet为标志 already, just和yet 表示到现在为止动作或状态已经、刚刚或还没有发生。 He has already got her help. 他已得到她的帮助。 He has just seen the film. 他刚刚看过这场电影。 He hasn't come back yet. 他还没有回来。 * 以ever和never为标志 ever和never 表示到现在为止动作或状态曾经或从来没有发生过。 This is the best film I have ever seen. 这是我曾经看过的最好的一部电影。 He has never been to Beijing. 他从没有到过北京。 * 以动作发生的次数为标志若某一动作到现在为止已经发生了若干次,则要使用现在完成时。 He says he has been to the USA three times. 他说他已经去过美国三次了。 * 以so far为标志 so far往往表示到目前为止动作或状态已经发生。 He has got to Beijing so far. 到目前为止他已到了北京。 She has passed the examso far. 到目前为止她已经通过了。第三部分过去已经开始的动作一直延续到现在, 甚至有可能继续延续下去,我们可以从动作“延续”的特性和“时间”点段的区分入手,进一步学习现在完成时。 *“终止”、“延续”要转换

现在完成时现在完成时一、结构： have / has +动词过去分词 haven’t / hasn’t + done Have / Has + 主语+ done 二.用法：表示到说话时刻为止已经做或尚未做过的动作。常用already, yet, so far, by now, since two days ago, for a few days 等词语作状语。注：give, see, come, arrive, leave(离开)，begin, start, finish, join, become, borrow, lend, die, end 等点时间动词可以用于完成时，但在肯定句中不能与表示一段时的since和for 短语连用，因为点时间动词不能延续，而在否定句中可以与表示一段时间的for短语连用，因为否定的点时间动词可以看作是一种可延续的状态。 Mike has come for a year.( 〤) Mike has been here for a year( √) Mike hasn’t come for a year.（√）过去完成时表示截止到过去某一时刻或在过去的动作之前（过去的过去）已经做或尚未做的动作。 B y (=up to )last weekend we hadn’t got any information.
