look after 中色 after 是介词,宾语放其后

如： I must look after my pet dog.
I have to look after him.

不明白的再问哟,请及时采纳,多谢!after也是副词啊！对after介词在...以后After graduation he went abroad. 毕业后他去了国外。 At half after ten it began to rain. 在十点半下起雨来。连接词 conj. 在...之后I will tell you after they leave. 他们走后我再告诉你。 副词以后,之后They arrived shortly after. 不久以后他们抵达了。 2. 在后面,随后Tom went on Monday, and Mary left the day after. 汤姆星期一走的,玛丽第二天就离开了。 但在look after 短语中是介词
