in,after和later三者的区别in five years/five years later/after five years都有五年之后的意思那到底他们有什么区别呢?好像有一个是从现在算起的五年后，一种只能用于过去时，还有一种不太清楚。到底各对应哪种呢？能否具体讲解．谢谢

in five years :在五年之内
Prices doubled in five years.
五年间物价上涨了一倍。
five years later : 五年之后
The war was over five years later.
五年后战争结束。
after five years: 五年之后
After five years, their marriage suddenly went wrong.
五年之后，他们的婚姻突然破裂了。

in five years用于将来事态，I'll return in five years.
after five years用在过去时，He returned after five years.
five years later是不是使用范围更广捏~

in five years is used by future tense.five years later is used by past tense.after five years is used by future tense or past tense.
