try it on ,get on it .

题目

try it on ,get on it .
on 是介词,为什么会有上面两种用法?应该是代词在动副词组之间,在动介词组之后啊

答案

try it on ,get on it 都是动介词组,当一个动词加上一个介词可以与介词本身的意思无关.
例如look after意思是照顾.
try it on有两个意思.一是试穿衣物,e.g.Try on the shoes before you buy them.
另一意思是明知不准做,却希望别人没异议.
e.g.Don't try anything on with me,you will be sorry.
get on有三个意思.一是进展,Everything is getting on very well.一切进行得很顺!另一意思是出人头地,He is sure to get on in the world.他一定会出人头地.第三种意思是登上车.If you don't get on this bus,you will be late.如果你不登上这车,你便会迟到.
动词+介词的组合在很多书都会列出他们组合后的意思,不妨有时间多看!
