Tā yǐjīnɡ bìyè dàxué le.
False: 她已经毕业大学了。
Tā yǐjīnɡ dàxué bìyè le.
True: 她已经大学毕业了。
“毕业”本身已有一个直接宾语,如果要指明毕业的学校,则应把“大学”移到谓语“毕业”之前,做状语。
毕业 already contains a direct object, and can not be followed by another object. 大学 must be placed in front of the predicate 毕业 as an adverbial adjunct to show the place of graduation.
