B. to be graduating
C. being graduated
D. having been graduated
选择哪一个答案，为什么选择这个选项

Answer 1

用A. 这里 graduating 是动名词做介词 after 的宾语.
B 错. graduate 是一次性的动作, 不能用进行时. 进行时要用于持续性的动作.
C 被动语态, 被毕业?
D 被动态完成时也不对. 已经被毕业了?

Answer 2

答：应该选A. graduating.

Answer 3

after…为介词短语结构
A中单词为名词毕业的意思。构成介词短语
B 不定时不能跟在介词after后
c为现在进行时态，且毕业不能延续，也就是不能一直毕业。句子意思是已经毕业。
d. 现在完成时不对。。
故选A.
