happen, occur, take place,come about 和break out 用法区别

这些词或短语都有“发生”的意思，但用法各不相同，区别如下：

(1). 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，例如：

The mee ting took place last night.会议昨晚举行。

(2) .happen 常常有“偶然”的意思，多用于客观事物、情况的发生。例如：What happened to you? (一般不说：What did you happen?)

(3). occur 作“发生、想到、突然想起”解，指有计划使某些事或效果“发生”。有时强调“呈现”于人的知觉。其意义相当于happen，例如：What has occurred? (=What has happened?)

(4). come about 表示“发生、产生”，多指事情已经发生了，但还不知道为什么，常用于疑问句和否定句，例如：When Mother woke up, she didn’t know what had come about.

(5). break out 意思为“发生、爆发”，常指战争、灾难、疾病或者争吵等事件的发生，也可以表示突然大声叫喊等，例如：Two world wars broke out last century.

occur vi. 1 发生2 想起，想到

常用搭配：sth. occurs to sb.:某人突然想起某事；

It never occurred to sb. that....:某人从未想到...

Suddenly a good idea occurred to her. It never occurred to us that the well-dressed man was a pickpocket. 我们决没有想到，那个衣冠楚楚的人是个扒手。

happen vi 1 发生（多指偶然发生）2 碰巧，恰巧（不可用被动）]

常用搭配：happen to sb.:某人会怎样

happen to be…;

happen to do…;

it (so) happened that…

eg The accident happened during a stormy night. What will happen to them if they lose their way in the forest? He happened to be out shopping when the fire broke out.= It (so) happened that he was out shopping when the fire broke out.火灾发生时，他碰巧外出购物。

happen 常指一件事出乎意料地发生了，强调偶然性，happen 还有碰巧; 在以具体事物、事件为主语时happen 和occur 往往可以通用。如，The explosion occurred / happened 5 minutes ago.

如果所发生的事不具体，happen 比occur 要好。如，I don't know what happened after I left.

take place 1 发生2 举行（侧重事先计划好或安排好的事情，不能用被动）eg Do you know when and where the story took place? The Olympic Games take place every for years. In 1919，the May 4 th Movement took place in China. occur 还有"被想到"，take place 还有"举行"之意。此时它们不可以互换。These plants only occur in Africa 的意思为"这些植物只是在非洲才有。"此句中occur 意思为" 存在"。
