1.After作介词 prep. ，后面可以加做宾语的动名词（V+ ing），名词，代词，翻译成 “时间上或者空间上在...之后”

如：He came back after 5 o‘clock 他五点以后返回来了。

       He ran after the bus. 他在那辆公交车后追着跑。

       I  went to bed after having finished  my homework   我完成作业后睡觉了

       I will go to bed after drinking the milk. 我喝完牛奶后要睡觉

2.After 也可以当连词 conj.，用来连接2个句子

    I went to bed after I have finished  my homework  我完成作业后睡觉了 

3. After 和 in 的区别

意思都是“一段时间以后”

"一般 " After用在过去时，in用在将来时

He will come back after 5 o‘clock  (X 错误)

He will come back  in  5 o‘clock  (V 正确)
