"I graduated from [school name]" 是表示你毕业于某个学校的常用说法。其中，"graduated" 是 "毕业" 的意思，"from" 是 "从...来" 的意思。

例如：

I graduated from Harvard University. (我毕业于哈佛大学)
I graduated from Beijing Normal University. (我毕业于北京师范大学)
I graduated from Peking University. (我毕业于北京大学)

注意： "graduated" 可以换成 "received my degree from" 来表达相同的意思。

例如：

I received my degree from MIT. (我从麻省理工学院拿到了学位)
I received my degree from Tsinghua University. (我从清华大学拿到了学位)
