告诉你最本质的解释:
A.in two hours 表示从现在起在过两小时,所以常用于一般将来时态
e.g.It's seven o'clock now.He will be back in an hour.So he will be back at 8:00.
B after two hours 表示过去某一时间的两小时以后
e.g.He got up at six this morning.After two hours,he was already in Beijing.
C two hours later = after two hours
D for two hours 表示某个行为或状态持续了两个小时,或者总共耗时两个小时
