Question

in,at,from,on该在什么时候用?
像下面的句子：1、My birthday is _____ May 21st.2、My father was there _____1942.3、Were you ____ school yesterday?4、They always do their homework _____ the evening.5、Can you come ____ Monday?6、She's not here.She's _____ the butcher's.

Answer 1

1.on
2.in
3.at
4.in
5.on
6.from
从以上总结出,有具体日期的时候用on
在年月季节或表示一段时间,早中晚用in但有具体日期时,一定得用on
at一般接小地点,或者具体时间如at7：00
from是从……的意思一般接的是地点,用这个时可以根据句意来判断
