这个和学校老师的解答一致

【 在 CISO 的大作中提到: 】
: n this case, "at school" and "in school" have slightly different meanings:
: "At school" typically means being physically present at the location (the school building) but doesn’t necessarily mean you were there to study. So, "I ate rice, drumstick, and some greens at school" is correct if you're simply talking about where you ate.
: "In school" often refers to being enrolled or actively involved in school as a student. For example, "I am in school" implies that you are a student.
