at对应时间点,具体到分钟.
at 14:25pm
in对应时间段
in a while,in May
on跟时间搭配时多是跟星期几...
on monday...
当有last,this,next修饰时,无需再用介词.
好像用early或late来修饰时要换成on,如:on the early morning.具体忘了(毕业太久了),看看别人是怎么说的.

1. last,next前面不能加"in","on","at"等时间介词
2.不能改成"on".同时,形容词要加在the和morning之间,the不能省略

1 因为有了last ;如 last time , last month 一样;
2 不能用on ;只能用 in .

.in the morning

不是
