v.(动词)

1. 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。
2. 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。
3. 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。

v.(动词)

happen to sb, happen with sb

这两者都是“某人发生了某事”的意思,前者可指坏事,也可指好事; 而后者多指坏事。试比较:

What's happened to her?

她怎么了?

What's happened with her?

她出什么事了?

happen, occur, take place

这三者均可作“发生”解。它们的区别是:

1.happen和occur往往表示事情的发生带有偶然性, happen是一般用语, occur是较正式用语; take place常指按计划“发生”。例如:

The explosion happened〔occurred〕 during an exercise near the town.在离市镇不远的地方演习时发生了爆炸。

The talk is scheduled to take place tomorrow morning at eight o'clock.预定明早8时举行会谈。

2.当表示具体事情的名词作主语时,用happen和occur都可,如果不是表示具体事情的词则多用happen。在否定句里一般用occur。例如:

These events happened〔occured〕 last year.这些事是去年发生的。

What happened after I left?我走后发生了什么事情?

It didn't occur to him to ask for help.他没想到请别人帮忙。

下面两个句子意思不同:

It happens that I am there.

碰巧我在那里。

It so happens that I am there.

事情发生得那么凑巧,我在那里。

第1句中的it是形式主语,第2句中的it是第三人称代词,相当于the thing。

occur，happen，take place

三者都表示“发生”，都是不及物动词。

occur指“发生”时可与 happen 换用，但后接to sb．／sth．时，两者含义不同：；occur to sb．／sth． 指“某种思想等呈现于某人的知觉中”。

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。

take place表示“发生”，可与 happen 或occur换用，但其后面一般不接 to sb．／sth．结构；指必然会发生的事情时，多用 take place；此外take place 还可表示“举行某种活动”。

• ☆ 直接源自中古英语的happenen，意为机缘，偶然发生。
