出入大学的感受可以用英文表达为 "the experience of entering/leaving college/university"。

其中的 "experience" 指的是经历，这个词来源于拉丁文 "experientia"，意思是 "having or undergoing experience; undergoing trial or testing"。

"Entering/leaving" 分别指的是进入和离开，这两个词来源于拉丁文 "entrare" 和 "lēavere"。

"College/university" 分别指的是大学和大学，这两个词来源于拉丁文 "universitas" 和 "collegium"。

On the other hand, I was sad to say goodbye to my friends and the academic environment I had grown so fond of. 离开大学的经历对我来说是甜蜜与苦涩的。一方面，我很高兴能够开始我的职业生涯，看看未来会给我带来什么。另一方面，我很难过要和我的朋友们告别，也很难过要离开我那么喜欢的学术环境。
