happen to do sth和happen doing sth 有什么区别

碰巧

happen 是发生的意思。happen to sb. 是它的固定搭配。sth. happen to sb. 是某事发生在某人身上。比如：What happen to you ? 是你身上发生了什么?简介：happen是不及物动词,作“发生”解时,可指偶然的事故,也可指有计划或无计划发生的事。一般以事件、环境、形势等作主语,表示“某人发生某事”时,须以介词to 引出“某人”。作“碰巧”解时,其后须接动词不定式构成复合谓语,可由人称代词或无人称代词it作主语。与if连用则可使语气委婉。happen也可如be般用于存在句中,其时态须与其后的主语保持一致。happen是瞬间动词,不能与表示一段时间的状语连用,也不能用于进行体。

区别：用法不同。happen：happen指“偶然发生”时，主语为“事”；当主语是“人”时，意为“碰巧”。happen to sb．／sth． 指不好的事情发生在某人（物）身上。相关句子：1、What happened to you?你怎么了?2Maybe something unexpected happened.也许发生了意想不到的事。3、I happened to see him on my way home.我在回家的路上碰巧看见了他。take place 表示“发生、举行、举办”，一般指非偶然性事件的“发生”，即这种事件的发生一定有某种原因或事先的安排。相关句子：1、Great changes have taken place in our hometown during the past ten years.在过去的十年里，我们家乡发生了巨大的变化。2、The Olympic Games of 2008 will take place in Beijing.2008的奥运会将在北京举行。

happenfor和happento的区别如下。1、happenfor指发生的原因。2、happento指发生于，偶然发生，强调偶发性。同近义词：chanceto。3、happen指发生，使遭遇，碰巧。同近义词：occur、proceed、chance。

happen to 后面跟的是人名、公司、或其他集合名次和代名词 What happened to you? It happens to everybody. The same thing happened to John and his family last week. Please make sure this doesn"t happen to us again. happen at 后面跟的是时间、地点等状词,补充说明发生的那件事情. The accident happened at near the corner of Main Street and Hill Avenue. The recent earthquake in Janpan happened at 1:48pm the day before yesterday.

偶然

happen to do sth.碰巧干某事 Oh,I happened to pass by.我那时刚巧路过. happen to sb.to是介词,某事发生在某人身上 He is so poor;bad things always happen to him. 他真可怜,不幸的事情总是降临到他头上.

happen是不及物动词，它的用法常见的有如下几种情况： 1. 表示“某地(某时)发生了什么事”，常用“sth.+ happen +地点/时间”这一结构来表达，此时主语应是事情。例如： The story happened in 2003. 这个故事发生在2003年。 An accident happened in that street. 那条街上发生了一起事故。 2. 表示“某人出了某事(常指不好的事)”，要用“sth.+ happens to sb.”这一结构来表达。例如： A car accident happened to her this morning. 今天上午她发生了交通事故。 What happened to you? 你怎么啦？ 3. 表示“某人碰巧做某事”，要用“sb.+ happen+ to do sth.”这一结构来表达。例如： I happened to meet a friend of mine in the street yesterday. 昨天我碰巧在街上遇到了我的一个朋友。 4. happen表示“碰巧或恰巧发生某事”时，还可用“It happens / happened that...”这一结构来表达。例如： It happened that Brian and Peter were at home that day. 碰巧那天布莱恩和彼得在家了。 It happened that he had to take part in a meeting that afternoon. 碰巧那天下午他不得不参加一个会议。 注：that从句中的主语是人时，此种结构可以与“sb.+ happen + to do sth.”结构互换。例如： It happened that Brian and Peter were at home that day. = Brian and Peter happened to be at home that day. happen 是个常用词，也是历年高考经常考查的词语之一。下面笔者就其用法进行归纳总结，以备同学们学习时参考。 1. 一般指“发生意外的事或事故”。如： How did the accident happen yesterday? 昨天的事故是怎么发生的？ 2. 表示“某人发生（出了）某事；某物发生了某种情况”。即： sth. happens to sb. /sth. 如： If anything happened to him， please let me know. 万一他有什么不测，请通知我。 What has happened to your car? 你的车怎么了？ 3. happen 在口语中可用进行时态，相当于 go on 。如： A strange thing was happening (= was going on) in the village recently. 最近村子里发生了一件奇怪的事。 4. happen 后面接不定式时，意为“碰巧、恰好”。如： Someone in the office happened to notice her. 办公室里碰巧有人注意到她。 I happened to be out when he called. 他来访时我刚好出去了。 5. 当 happen 后面的不定式所表示的动作正在进行或已经完成时，须用不定式的进行式或完成式。如： He happened to be sleeping when his mother came into the room. 当他妈妈进屋时，他碰巧在睡觉。 He happened to have known the secret， so I needn"t tell him. 他碰巧已经知道了这个秘密，所以我不需要再告诉他。 6. 句型“ It happens (happened) that …”中 it 是形式主语， that 引导的从句是句子真正的主语，此复合句可与简单句互换。如： It happened that I had no money with me. = I happened to have no money with me. 我碰巧身上没带钱。 It happened that Tom was singing in the next room. = Tom happened to be singing in the next room. 汤姆碰巧在隔壁屋里唱歌。 It happened that my brother hadn"t seen the note. = my brother happened not to have seen the note. 我弟弟碰巧没有看到那张条子。 7. 句型“ There happened to be …”表示“碰巧有……”。如： There happened to be a heavy rain on my way home. 我回家的路上碰巧下大雨。 8. 习语“ as it happens (happened) ”表示“恰好，碰巧”。如： As it happens， I have left the book at home. 我碰巧把书丢在家里了。 We met her only yesterday， as it happened. 我们只是在昨天才与她偶然相遇。 9. 习语“ whatever happens (happened) ”表示“不管发生什么情况”。如： Whatever happened， I must be calm. 不管发生什么情况，我都要镇静。 We"ll go along together whatever happens. 不管发生什么情况，我们都要一起干。 10. 可用在疑问句和条件句中，表示婉转的语气。如： Do you happen to know his telephone number? 你知道他的电话号码吗？ If you happen to go there， would you ask him about it? 如果你有机会去那儿，可否问问他有关此事的情况？ 11. happen 与 take place 的区别： ① take place 指按计划或安排发生的事，尤其指重大事件。如： Great changes have taken place in my hometown in the last ten years. （不用 happen ） 我的家乡在过去十年里发生了巨大的变化。 ②指发生未预料到的小事情时可用 take place ，但一般不用进行时。 ③ take place 表示“举行、进行”（ = be held ）。如： When will the soccer game take place? （不用 happen ） 足球比赛什么时候举行？

楼上误解了 Occur to是指“突然想到了什么”,跟come up with sth很相似,例如,It occurs to me that i have to go now.我突然想到该走了. Happen to是指某件事发生在了某人身上. 可见两者完全不同,望楼主慧眼采纳^^

tohappento不是一个常用语,happento(发生于...)才是常用语你把to这个词从原文中拉出来了,其实应该是betodosth,表示将来会这样,和begoingtodosth意思相同.连在一起就是don"tknowwhatistohappentothem.意思是不知道什么将要发生于他们.因为前面是不定式,所以happen就用原型可以了,如果是过去时,比如,anaccidenthappenedtohim就是用happenedto了

happen是不及物动词，它的用法常见的有如下几种情况： 1. 表示"某地（某时）发生了什么事"，常用"sth.+ happen +地点/时间"这一结构来表达，此时主语应是事情。例如： The story happened in 2003. 这个故事发生在2003年。 An accident happened in that street. 那条街上发生了一起事故。 2. 表示"某人出了某事（常指不好的事）"，要用"sth.+ happen+to sb."这一结构来表达。例如： A car accident happened to her this morning. 今天上午她发生了交通事故。 What happened to you? 你怎么啦？ 3. 表示"某人碰巧做某事"，要用"sb.+ happen+ to do sth."这一结构来表达。例如： I happened to meet a friend of mine in the street yesterday. 昨天我碰巧在街上遇到了我的一个朋友。 4. happen表示"碰巧或恰巧发生某事"时，还可用"It happens / happened that..."这一结构来表达。例如： It happened that Brian and Peter were at home that day. 碰巧那天布莱恩和彼得在家了。 It happened that he had to take part in a meeting that afternoon. 碰巧那天下午他不得不参加一个会议。 注：that从句中的主语是人时，此种结构可以与"sb.+ happen + to do sth."结构互换。例如： It happened that Brian and Peter were at home that day. = Brian and Peter happened to be at home that day.

不是_appen to不可以看作情态动词，因为它是行为动词可以直接做谓语动词，中文意思是“某人或某物发生什么事，碰巧”

不是。系动词是指本身有词义，但不能单独用作谓语，后边必须跟表语，亦称补语（形容词），构成系表结构说明主语的状况、性质、特征等情况。有seem, appear, prove, turn out, grow ，sound, smell, feel, taste, become etc . .

be happened to这种说法不正确，因为happen是不及物动词，不能用于被动结构。happen常用句型:happen to do sth碰巧做某事;What happened to sb?某人发生了什么事?

happentodosth.是固定词组，“碰巧做某事”的意思Ihappenedtositbyherinthecinema.在电影院我碰巧坐在她旁边。meetupwith则通常指

happentodosth碰巧做某事whathappenedtoyou?你怎么了?问别人怎么了happen后面一般都加介词to。不做固定搭配时happeninsomeplace发生在某地。做固定搭配时happenin[美]偶然到...(来)happeninwith偶然和...碰见

Happen to do something意外发生去做某事，不在计划之内，常常表达非常突然的去做

happenedon：偶然遇到或发现hehappenedonthebookinansecondhandbookstore.他碰巧在一家旧书店里发现了这本书。happenedwith：aboutwhathappenedwithus.我们之间的事thingsfinallyhappenedwithkate.我跟凯特终于有进展了happenedto：发生于；偶然发生letmetellyouwhathappenedtomeonce.让我告诉你曾经发生在我身上的事。happenedfor：that"skindofhowithappenedforandrew.这就类似在安德鲁（拜纳姆）身上所发生的。inbooksthishasalreadyhappenedforencyclopedias.对于百科全书来说，这一变化已经来临了。

happen的基本含义是“发生”，指某事件或情况的出现。而happen to则有碰巧，恰好的含义或引出某种情况发生在某人或某事物身上。这里给大家总结了一个它们基础知识的表格，可以先简单了解一下先u273au25df(u2217u275bu0e31u1d17u275bu0e31u2217)u25deu273a了解完它们的基础知识后，现在就来看看它们的具体区别吧u10da(u30fbu2200u30fb )u10da区别一：基本含义不同happen的基本含义是“发生”，指某事件或情况的出现。而happen to则有碰巧，恰好的含义或引出某种情况发生在某人或某事物身上。例句：①What happened in the end? 结局是怎样的？②Do you happen to know the time? 你刚好知道现在是几点吗？区别二：语法结构不同happen后通常接事情或现象作为宾语，描述一种状态或事件。而happen to则需要接事物或人，描述主语对对象的动作或状态。例句：①Accidents can happen at any time. 任何时候都可能发生事故。②I happen to have some time this afternoon. 我今天下午正好有些时间。区别三：使用场合不同happen是一个非常常见的词，用于描述各种事件或情况的发生。而happen to通常用于强调某种情况或事件恰好发生在某人或某事物身上，或询问某人是否知道或具有某种信息或能力。例句：①A strange thing happened to me yesterday. 昨天我碰到了一件奇怪的事。②Do you happen to have her phone number? 你偶然有她的电话号码吗？

发生在某人身上

后面跟动词，名词。happento+动词原形碰巧，偶然发生，巧遇，happento+名词，发生（某事件），对?产生影响，临到...头上某情况，尤指不幸的事。happento用法，一般以事件，环境，形势等作主语，表示“某人发生某事”时，须以介词to引出“某人”，作“碰巧”解时，其后须接动词不定式构成复合谓语，可由人称代词或无人称代词it作主语，与if连用则可使语气委婉。

区别：用法不同。happen：happen指“偶然发生”时，主语为“事”；当主语是“人”时，意为“碰巧”。happen to sb．／sth． 指不好的事情发生在某人（物）身上。相关句子：1、What happened to you?你怎么了?2Maybe something unexpected happened.也许发生了意想不到的事。3、I happened to see him on my way home.我在回家的路上碰巧看见了他。take place 表示“发生、举行、举办”，一般指非偶然性事件的“发生”，即这种事件的发生一定有某种原因或事先的安排。相关句子：1、Great changes have taken place in our hometown during the past ten years.在过去的十年里，我们家乡发生了巨大的变化。2、The Olympic Games of 2008 will take place in Beijing.2008的奥运会将在北京举行。

happen on和happen to的区别是意思不同、用法不同、侧重点不同，含义如下：一、意思不同1.happen on意思：巧遇，偶然发现2.happen to意思：发生在…身上二、用法不同1.happen on用法：不及物动词，作“发生”解时，可指偶然的事故，也可指有计划或无计划发生的事，一般以事件、环境、形势等作主语。2.happen to用法：一般以事件、环境、形势等作主语，表示“某人发生某事”时，须以介词to 引出“某人”，作“碰巧”解时，其后须接动词不定式构成复合谓语，可由人称代词或无人称代词it作主语，与if连用则可使语气委婉。三、侧重点不同1.happen on侧重点：后面加的可能是时间/地点等名词（短语），而这个短语恰好是要求用介词on的。2.happen to侧重点：happen to是固定搭配。

"Occur to"和"Happen to"的区别在于它们的用法和意义。"Occur to"是指某个想法或者思路突然冒出来，通常表示自己在某个时刻想到了某件事情或者解决方案。例如：It occurred to me that I could use my phone to take a picture of the document. (我突然想到可以用手机拍照文档。)"Happen to"则表示偶然或者意外发生的事情。例如：I happened to meet my old friend on the street. (我碰巧在街上遇到了老朋友。)因此，如果要表达某个念头或者想法突然浮现，使用"occur to"；而如果要表达某种偶然事件的发生，使用"happen to"会更加合适。
