口袋妖怪叶绿代币换:happen on 和 happen to 有什么区别

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.
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.
