be enrolled in后面接什么？

这个要看具体情况
看一下几个句子
a learner who is enrolled in an educational institution... 此处就是接的教育机构。

I am a new associator in Debian world and I want to be enrolled in mail list. 而这一句呢,就是希望得到邮件告知。

反正这个短语后面肯定不接时间的。

被...大学录取，登记某个课程之类的

be enrolled in the university of...

be enrolled in a course

Be enrolled in school. 或 be enrolled in a program.
