Question

He would have finished his college education, but he ____ to quit and find a job to support his fam

答案C 我选的A 不是过去完成时吗?
sorry
A. had had
B. has
C. had
D. would have

Answer 1

前句为过去将来时，意思为“他本可以完成大学的学业”，所以后句也应该与过去时有关，排除BD，因为过去完成时代表“在某一时间前发生的事（即过去的过去）”，所以根据句意排除A，因此选C

Answer 2

这里用过去时就可以了，这里have to做短语用，是不得不退学。

Answer 3

would have finished..
本可以完成他的大学学业
后半句完全可以是一般现在时

这个。。。C和A是什么？
