in school和at school都表示在学校上学的意思,区别如下: in school是把学校这个建筑物看作是一个面,不是一个点,表示在学校里面学习,相对于有工作,强调主语的身份是学生,而不是有工作的人。当学校比较大的时候,更常用in school,例如: We are in school. We study English in school. My daughter is still in school. She doesn’t work at school是把学校这个建筑物看作是一个点,即在学校这个地点,相对于在家里或在校外。当学校比较小,如中小学时,常用at school,如: My son was at school yesterday. My son was at nursery and my daughter was at school. How is it going at school?
