在英语中,重读闭音节的动词数量相对较多。以下是一些常见的重读闭音节动词的例子:
occur的过去式和过去分词 occur过去式是什么
occur的过去式和过去分词 occur过去式是什么
1. Admit
2. Begin
3. Cancel

5. Control
6. Enter
7. Forget
8. Offer
9. Open
10. Permit
11. Prefer
12. Proceed
13. Visit
14. Wonder
这只是一小部分例子,且列表远不全面,因为英语中存在众多的动词,不可能一一列举。还请了解,某些动词在不同的语境中可能有不同的重读形式。为了建立更全面和准确的动词列表,您可以参考英语词典或在线资源。
在英语中,重读闭音节的动词是指在发音时,重音落在词尾的闭音节上的动词。这类动词通常在过去式和过去分词时,词尾的辅音字母会加倍。例如,"stop" 变为 "stopped"。
这类动词在英语中是相对常见的,但数量并不是非常多。下面是一些常见的重读闭音节的动词:
- stop -> stopped
- clap -> clapped
- hop -> hopped
- plan -> planned
- rob -> robbed
- sit ->rot sat
- win -> won
- swim -> swam
- begin -> began
- run -> ran
- admit -> admitted
- prefer -> preferred
- regret -> regretted
- occur -> occurred
- control -> controlled
- transfer -> transferred
这些只是一些例子,还有更多的重读闭音节的动词。总的来说,这类动词在英语中并不是非常多,但它们在日常会话和写作中经常出现。
在英语中,重读闭音节的动词的数量相对较多。闭音节是指以辅音结尾的音节,而重读闭音节是在该音节上有重音。以下是一些常见的重读闭音节动词的例子:
停止(stop)
拆除(break)
发生(happen)
喝(drink)
改变(change)
回答(answer)
跳(jump)
带来(bring)
看(look)
坐(sit)
这只是一小部分例子,实际上还有很多其他的重读闭音节动词。对于具体数量,很难给出确切的数字,因为英语中的词汇量非常庞大,而且语言在不断演变

英语动词有五种基本形式,即动词原形、第三人称单数(现在式)、过去式、过去分词和现在分词。
sob啜泣1. 第三人称单数的构成方法
与名词的单数变复数规则大致一样,即:
(1) 一般情况下由动词后加-s构成:work / works,read / reads等。
(2) 以s, x, z, sh, ch 以及字母o结构的动词,后加-es:guess / guesses, mix / mixes, go / goes, buzz / buzzes, finish / finishes, catch / catches等。
(3) 以辅音字母加y结尾的动词,应将y改为i 再加-es:fly / flies, study / studies等。
【注】① 有个别的变化不规则,如he / has, be / is等。
② 词尾-s和-es 读音规则是:在s, x, z, sh, ch 后的es读作[iz],其余的读作[z]。
2. 过去式和过去分词的构成方法
分规则变化和不规则变化两种。不规则变化需逐个记忆,规则变化遵循以下原则:
(1) 一般情况下,在动词后加ed构成:work / worked, staTo dispatch, as by a communications medium:y / stayed, shout / shouted等。
(2) 在以-e结尾动词后只加d:close / closed, like / liked, live / lived, ile/ iled等。
(3) 以辅音字母加y结尾的动词,应将y改为i 再加-ed:study / studied, carry/ carried等。
(4) 以重读闭音节或r音节结尾且末尾只有一个辅音字母动词,要双写末尾的辅音字母再加-ed:stop / stopped, admit / admitted, refer / referred, prefer / preferred等。
【注】(1) 以字母l结尾的动词,若末尾一个音节为重读音节,则必须双写l再加-ed,如control / controlled,但若末尾一个音节为非重读音节,则可双写l(英国英语)或不双写l(美国英语),如trel / trel(l)ed。
(2) 动词picnic(野餐)的过去式和过去分词是picnicked,不是picnd。
(3) 词尾-ed 读音规则是:在清辅音后读作[t],元音和浊辅音后读作[d],在辅音[t]或[d]后读作[id]。
3. 现在分词的构成方法
(1) 一般情况下,在动词后加-ing构成:work / working, sleep / sleeping, wait / waiting等。
(2) 在不发音的-e结尾动词去掉e后再加-ing:ile / iling, move / moving 等。
(3) 以重读闭音节或r音节结尾且末尾只有一个辅音字母动词,要双写末尾的辅音字母再加-ing:sit / sitting, plan / planning, refer / referring, occur / occurring等。
(4) 以字母ie结尾的动词,通常将ie改为y,再加ing:die / dying, lie / lying, tie / tying等。
【注】(1) 以字母l结尾动词,若末尾一个音节为重读音节,则必须双写l再加ing,如control / controlling,但若末尾一个音节为非重读音节,则可双写l(英国英语)或不双写l(美国英语),如trel / trel(l)ing。
(2) 名词变复数、形容词和副词变比较级和、动词变过去式和过去分词等都有“改y规则”,但动词的现在分词没有“改y规则”。
(3) 动词picnic(野餐)的现在分词为picnicking,不是picnicing。
字尾加ive或ful或tion或less之类的
取款机
是有现在分词的,现在分词就是动词现在式,一般我们常说现在分词而不说动词现在式,也有少部分说现在式
注意:quarrel, signal, trel中的l 可双写(英国英语)也可不双写(美国英语)现在进行时的构成 be + doing
否定句 be 后加 not
一般疑问句 be 提句首
特殊疑问句的变法 疑问词 + 一般疑问句
现在分词的三种构成 一般加 -ing
不发音的 e 结尾,去 e 加 -ing
重读闭音节结尾,一元加一辅,双写加 -ing
英语动词是由音节构成的.音节又可以分成重读开音节,重读闭音节,重读 r 音节,重读 re音节和重读字母组合音节.在重读闭音节和重读r音节中,若单词是以单个辅音字母结尾,则要双写再加ed或ing
加-ed/-ing时,其末尾字母需要双写的动词

一.名词性从句
注意:在demand、order、suggest、decide、insist, desire, demand, request, command等表示要求、命令、建议、决定等意义的动词后,宾语从句常用“(should)+ 动词原形”。例如:名词性从句的连接词可分为三类:
连接词:that, wher, if (不充当从句的任何成分)
连接代词:what, whatr, who, whor, whom, whose, which.
连接副词:when, where, how, why
1. 主语从句
作句子主语的从句叫主语从句。主语从句通常由从属连词that,wher,if和连接代词what,who,which,whatr,whor以及连接副词how,when,where,why等词。that在句中无词义,只起连接作用;连接代词和连接副词在句中既保留自己的疑问含义、又起连接作用,在从句中充当从句的成分。例如:
What he wants to l us is not clear. 他要跟我们说什么,还不清楚。
Who will win the match is still unknown. 谁能赢得这场比赛还不得而知。
It is known to us how he became a writer. 我们都知道他是如何成为一名作家的。
Where the English ning will be held has not yet been announced. 英语晚会将在哪里举行,还没有宣布。
有时为避免句子头重脚轻,常用形式主语it代替主语从句作形式主语放于句首,而把主语从句置于句末。主语从句后的谓语动词一般用单数形式。常用句型如下:
(1) It + be + 名词 + that从句
(2)It + be + 形容词 + that从句
(3)It + be + 动词的过去分词 + that从句
(4)It + 不及物动词 + that 从句
另注意在主语从句中用来表示惊奇、不相信、惋惜、理应如此等语气时,谓语动词要用虚拟语气“(should) +do”,常用的句型有:
It is necessary (important, natural, strange, etc.) that …
It is a pity (a shame, no wonder, etc.) that…
It is suggested (requested, proed, desired, etc.) that…
2. 宾语从句
名词句用作宾语的从句叫宾语从句。宾语从句的关联词与主语从句表语从句的关联词大致一样,在句中可以作谓语动词或介词及非谓语动词的宾语。
1. 由连接词that的宾语从句
由连接词that宾语从句时,that在句中不担任任何成分,在口语或非正式的文体中常被省去,但如从句是并列句时,第二个分句前的that不可省。例如:
He has told me that he will go to Shanghai tomorrow. 他已经告诉我他明天要去上海。
We must nr think (that) we are good in rything while others are good in nothing. 我们决不能认为自己什么都好,别人什么都不好。
I insist that she (should) do her work alone. 我坚持要她自己工作。
The commander ordered that troops (should) set off at once. 司令员命令部队马上出发。
2. 用who,whom, which, whose, what, when, where, why, how, whor, whatr, whichr等关联词的宾语从句相当于特殊疑问句,应注意句子语序要用陈述语序。例如:
I want to know what he has told you. 我想知道他告诉了你什么。
She always thinks of how she can work well. 她总是在想怎样能把工作做好。
She will give whor needs a warm support. 凡需要帮助的人,她都会给予热情的支持。
3. 用wher或if的宾语从句,其主语和谓语的顺序也不能颠倒,仍保持陈述句语序。此外,wher与if 在作“是否”的意思讲时在下列情况下一般只能用wher,不用if:
a. 主语从句并在句首时;b. 表语从句时;c . 从句作介词宾语时;d. 从句后有“or not”时;e. 后接动词不定式时。例如:
Wher there is life on the moon is an interesting question. 月球上有没有生命是个有趣的问题。
The question is wher she should he a low opinion of the test?
Everything depends on wher we he enough money. 一切要看我们是否有足够的钱。
I wonder wher he will come or not. 我想知道他来还是不来。
Can you l me wher to go or to stay? 你能否告诉我是去还是留?
4. 注意宾语从句中的时态呼应,当主句动词是现在时,从句根据自身的句子情况,而使用
不同时态。例如:
he studies English ry day. (从句用一般现在时)
he studied English last term. (从句用一般过去时)
I know (that) he will study English next year. (从句用一般将来时)
he has studied English since 1998. (从句用现在完成时)
The teacher told us that Tom had left us for America.
5. think, beli, imagine, supe等等动词引起的否定性宾语从句中,要把上述主句中的动词变为否定式。即将从句中的否定形式移到主句中。例如:
We don’t think you are here. 我们认为你不在这。
I don’t beli he will do so. 我相信他不会这样做。
3. 表语从句
在句中作表语的从句叫表语从句。表语从句的关联词与主语从句的关联词大致一样,表语从句位于连系动词后,有时用as if。其基本结构为:主语 + 系动词 + that从句。例如:
The fact is that we he lost the . 事实是我们已经输了这场比赛。
That’s just what I want. 这正是我想要的。
This is where our problem lies. 这就是我们的问题所在。
That is why he didn’t come to the meeting. 那就是他为什么不到会的原因。
It looks as if it is going to rain. 看上去天要下雨了。
需要注意的,当主语是reason时,表语从句要用that而不是because。例如:
The reason why he was late was that he missed the train by one minute this morning
4. 同位语从句
同位语从句说明其前面的名词的具体内容。同位语从句通常由that,可用于同位语从句的名词有a、demand、doubt、fact、hope、idea、rmation、message、news、order、problem、promise、question、request、suggestion、truth、wish、word等。例如:
The news that we won the is exciting. 我们赢得这场比赛的消息令人激动。
I he no idea when he will come back home. 我不知道他什么时候回来。
The thought came to him that Mary had probably fallen ill. 他想到可能玛丽生病了。
同位语从句和定语从句的区别:
that作为关系代词,可以定语从句,充当句子成分,在从句中作宾语时可以省略; that同位语从句时,起连词的作用,没有实际意义,不充当句子成分,一般不能省略。
试比较下面两个例句:
I had no idea that you were here.(that同位语从句,不能省略)
He you got the idea(that)this book gives you of life in ancient Greece?(that定语从句,作宾语,可以省略)
二. 虚拟语气
1.主语从句中的虚拟语气主语从句中的虚拟语气主要取决于某些形容词和过去分词,用来表示建议、命令、要求、惊异和失望等。其形式为:(should)+动词原形。
常这样用的形容词有:
appropriate适当的aisable适当的,合理的better较好的desirable理想的essential精华的imperative迫切的important重要的insistent坚持的natural自然的necessary必要的preferable优越的,较好的strange奇怪的urgent紧迫的vital极其重要的
过去分词有:
desired, demanded, ordered, requested, suggested, recommended, required等。
例如:
It is essential that you (should) win the voters’hearts.赢得选民的心是必要的。
It was suggested that he (should) join the club activities.有人提议他应该参加俱乐部的活动。
2.表语从句和同位语从句中的虚拟语气在表示建议、命令、主张、目的和愿望等名词后面的表语从句和同位语从句中谓语动词要求使用虚拟语气。其形式为:(should)+动词原形。
常这样用的名词有:
resolution决心,决议pray恳求decision决议motion提议suggestion建议preference选择proal提议a劝告recommendationdesire愿望demand要求requirement要求order命令necessity必要性request要求idea主意、想法例如:
He ge orders that the guests (should) be hospitably entertained.他下令热情款待这些客人。
His proal is that we (should) get rid of the bad habits.他提议我们应该摈弃这些不良习性。
3.宾语从句中的虚拟语气
1)某些动词后所接宾语从句中的谓语动词要求用虚拟语气,用来表示建议、命令和要求等。其形式为:(should)+动词原形。常这样用的动词有:
ask要求aise劝告determine决定decide决定command命令insist坚持intend打算move提议prefer宁愿proe提议order命令recommendrequest要求require要求suggest建议urge主张demand要求desire渴望direct命令例如:
He insisted that the meeting be put off.他要求推迟那个会议。
They proed that all the plans should be discussed at the meeting.他们建议所有的都应该在会上讨论。
2)在以it为形式宾语的复合宾语从句中也可以用虚拟语气,其形式为:(should)+动词原形。这一句型中使用的形容词(宾补)与主语从句中的虚拟语气所使用的形容词相同。例如:
We think it aisable that he (should) think deeply before acting.我们认为他在行动之前好好考虑一下才是明智的。
3)wish后面所跟的宾语从句中的虚拟语气表示某种不能实现的愿望。
其主要形式有三种:
表示对现在情况的虚拟:wish +主语+动词过去式或were表示对过去情况的虚拟:wish +主语+ had +过去分词表示对将来情况的虚拟:wish +主语+ would +动词原形。
例如:
I wish I knew what was going to happen.但愿我能知道要发生什么事。
She wished she had stayed at home.她懊悔的是她当时要是在家就好了。
I wish I were rich.我恨不得我很有钱。
注意:在表示对过去情况的虚拟时,有时也可以用下列形式:
wish +主语+ would(could)+ he +过去分词I wish I could he seen her last night.要是我昨天晚上能够见到她那该多好。
4. if条件句中的虚拟语气形式1)if非真实条件句所表示的设则是不可能或不大可能发生或实现的,句中的主句与从句都用虚拟语气。
在if非真实虚拟条件句中,主句和从句谓语动词主要有下面几种形式:
设类型条件从句谓语动词形式主句谓语动词形式与现在事实相反动词过去时(be用were)Should(would,could,might)+动词原形与过去事实相反Had +过去分词Should(would,could, might)+ he +过去分词与将来事实可能相反动词过去时(should+动词原形,were to +动词原形)Should(would,could,might)+动词原形
If there were no grity, we should not be able to walk.如没有引力,我们就不可能行走。
I wouldn’t he known what these were for if I hadn’t been told.如别人不告诉我,我就不知道这些东西是干什么的了。
2)正式文体中,有时可把虚拟条件句中的连词if省去,而将were,had, should等助动词(不包括行为动词)提到主语前面。如果句中没有were,had或should时,既不能省略if,也不能倒装。例如:
Were I to meet him tomorrow (= If I were to met him tomorrow), I should ask him about it.要是我明天见到他,我就会问他这件事的。
Should there be any trouble with the boiler, the automatic controlling unit would cut off the fuel oil supply.如锅炉出问题的话,自控装置会自动切断燃油的供给。
3)通常情况下,在非真实条件句中主句和从句的谓语动词所指时间是一致的,但有时也可能指不同的时间,这时要根据上下文的意思采用不同的谓语动词形式。例如:
If I were you, I would he taken his a.我要是你,我就采纳了他的建议。(从句指现在,主句指过去)
If the weather had been more forable, the crop would be growing still better.如果气候更适宜一些,庄稼会长得更好。(从句指过去,主句指现在)
5.含蓄虚拟条件句1)有时设的情况并不以条件从句形式表示出来,而是通过一个介词短语或其他方式表示。常用的词或短语有:without, but for, but that, otherwise, or, but等。例如:
Without your (=If we had not had your ), we could not he succeeded.要是没有你的帮助,我们就不会成功的。
But for electricity (= If there were no electricity), there would be no modern industry.要是没有电,就不会有现代工业。
He was hing a meeting; otherwise he would he come over to us.他当时正与他的学生进行讨论,否则的话他就来帮我们了。
He felt very tired yesterday, or he would he attended the party.他昨天很累,不然他就参加那个聚会了。
2)在某些暗含虚拟条件的简单句中,虚拟语气可通过上下文表现出来。谓语动词用should/ would be形式和should/ would he been虚拟形式。例如:
Any men in his ition would he done like that.任何人处在他的位置都会那么做的。
You should (ought to) he come earlier.你本应来得早点。
6.其他句型中的虚拟语气1)在would rather, would sooner, would just as soon, might as well和would prefer等后面所跟的从句中,也可以用虚拟语气,表示愿望,意为“宁愿、但愿”。其形式为:
①“would rather (would sooner…) +主语+谓语动词过去式”表示现在或将来的情况。
②“would rather (would sooner) +主语+动词过去完成式”表示过去的情况。例如:I’d rather he didn’t go now.要是他现在不走就好了I’d just as soon you had been here yesterday.要是你昨天在这里就好了。
2)在句型“It is (high/ about) time…”后面也可以跟虚拟语气,从句中常用过去式。有时也用“(should)+动词原形”,意为“该是……的时候了”。例如:
It is time that the boy (should) go to school.这个小孩该上学了。
3)在“if only”引起的感叹句中也要求用虚拟语气,表示愿望。
形式为:①用过去时或“would/ could +动词原形”表示与现在或未来事实相反的愿望。
②过去完成时表示与过去事实相反的愿望。例如:
If only you would listen to our a.要是你听我们的建议就好了。
If only I had not been busy last week!要是上周我不忙该多好啊!
If only she could marry me.但愿她能嫁给我。
注:if only也可以用于虚拟条件句中。例如:
If only I had more money, I could buy a car.要是我有更多的钱,我就可以买辆车了。
4)连接词“in case, lest, for fear that”可以用来虚拟语气。其形式通常为:“…lest (in case, for fear that) +主语+ should +动词原形”。Lest, for fear that句中的should可以省去,in case句中的should通常不省去,但是in case句中可以不用虚拟语气,而用陈述语气。Lest, for fear that后面也可以接其他形式。例如:
He took his coat with him in case it should rain.他带着雨衣以防下雨。
Care must be taken in using this mod lest overflow (should) occur.在使用这以方法的时候要谨慎小心,以免发生溢流现象。
1. A good friend of mine from when I was born showed up at my home right before I left for Beijing.
此句中有两个从句。1)介词短语做后置定语,只不过这个介词短语是由“from+宾语从句”构成的;when的从句做介词from的宾语。2)before的从句做时间状语。
2. Anyone who wants to stay in a ho has to pay their own way.
首先,被定语从句所修饰的名词是人时,词通常为who,whom,whose,that。此处,anyone是人却在从句中做主语,词为who或that。其次,先行词是anyone,所以用who。特别说一下,当先行词是人的时候,词who,因为that是在某些情况下替代who的。
3. His daughter is quite different from what she was five years ago.
4. We he settled the question of wher it is necessary fro him to study broad.
此句和句一样,介词短语做后置定语。“名词+ [of+名词] ”中,[of+名词]相当于形容词。此句的of短语是由“of+宾语从句”构成;wher的从句做介词of的宾语。
主语从句,宾语从句,表语从句,同位语从句中作原因状语都可以用why

过去式和过去分词构成法
bar闩住;禁止1)英语中大部分动词都以加-ed词尾的办法构成过去式及过去分词:
现在时(动词原形) 过去式 过去分词
work worked worked
appear appeared appeared
talk talked talked
play played played
这类动词称为规则动词(Regular Verbs)。
2)在加-ed 词尾时要注意几个问题:
a.若末尾已有字母e,则只加-d:
live —— lived please —— pleased free —— freed
b.若以“辅音(字母)+y”结尾,先变y为i再加-ed:
try —— tried study —— studied simplify —— simplified
c.若是以“一个元音字母+ 一个辅音字母”结尾,该音节又重读者,末尾字母要双写,然后再加-ed:
stop —— stopped fit —— fitted chat —— chatted
d.其他的词都直接加-ed:
lack —— lacked open —— opened repeat —— repeated
3)另外,还有几点值得注意:
a.以“一个元音+l”结尾的词,英国人都把l双写,美国人都不双写:
trel —— trelled (英),treled (美)
marvel —— marvelled (美),marveled (美)
b.l前若有两个元音,l一概不双写(英美都如此):
ral —— ralled appeal —— appealed
c.有少数词,尽管末尾音节并不重读,末尾辅音字母在英国仍双写:
worship —— worshipped (英) ,worshiped (美)
kidnap —— kidnapped (英), kidnapped (美)
但progarm—— programmed(英,美),progarmed(美国人有时用这种拼法)。
d.以x结尾的词,x不双写:
mix —— mixed fix —— fixed
4)在英语中,在加-ed词尾时,末尾字母双写的词常见的有:
ban
chop
drop
grip
knit
