但是在学校吃
可能是属于学校的一个行为呀
现在的学校不是带菜到学校吃
而是学校开饭菜给学生吃
你这个解释反而倾向于in了

如果是可选的菜才是at
是学校给你吃什么你必须吃，反而是in了

【 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.

楼上都没说对！我来说明：这种情况就是in school!!!

at school  表示行为是与学校本分事情有关的（比如工作、学校活动、学习）
in school  表示在学校这个场所里，侧重非本分行为。强调在这个场所里。吃东西明显跟学习没啥关系或者说强调在这个场所里，是最典型的in!!!

这么看确实，有点像我要到公司XXX，和我要去公司XXX，一样。都可以用。at和in最本质的区别就是一个是小型地方，一个是大型点的地方。可学校这玩意有大有小，导致了这样吧。

GPT 这么说

In this case, both expressions "what did you eat at school" and "what did you eat in school" are grammatically correct, but they can convey slightly different nuances.

1. **What did you eat at school?**
   - This expression emphasizes the location (the school) where the eating took place. It suggests that the focus is on the school as a place where meals were consumed, which could include cafeteria food, snacks, or meals brought from home.

2. **What did you eat in school?**
   - This expression can imply that the eating occurred during school hours or within the school environment. It may suggest a broader context, including not just meals but also snacks or food consumed during classes or breaks.

### Which Expression is Better?

- **Context Matters:** The choice between "at" and "in" depends on the context of the conversation. If you want to emphasize the location, "at school" might be more appropriate. If you want to focus on the experience of eating during school hours, "in school" could be better.

- **Common Usage:** In everyday conversation, both phrases are commonly used, and native speakers would understand either one without confusion. However, "at school" might be slightly more common when referring specifically to meals.

In summary, both expressions are valid, and the better choice depends on the specific context and what you want to emphasize.
