1. occur vi.发生, 出现
解析:【同】happen, take place
【衍】occurrence n.发生
【辨析】happen强调偶然性
There happen to be no money with me.
It so happens that...
take place指有计划的使某事发生
Great changes have taken place in my hometown.
occur则包括了以上二者的意消碰空义,比较含糊。
2. occur是一般用词,可指吵咐某事情偶然发生或者按照计划进行,在表示具体失去的名词作主语的时候,可与happen换用,拿瞎但比较正式,跟to短语时,表示“想到”,而不是“发生”,比如
I’m very sorry for all happened to you.
An idea occurs to me that going to Switzerland for traveling will be marvelous!
上面的解释得很清楚,以后英语问题放英语部分问哦~
