If they_______(not cooperate),our plan would have fallen flat.

He was praised for_____(make)such a contribution to the country.

He felt ashamed_________(do)such a foolish thing.

1 didn't cooperate
2 making
3 to do

1 haven't cooperated 个人觉得还是用现在完成时比较好，
2 making for是介词。介词后动词要用ing形式
3 to do be/feel ashamed to do是一个词组。固定搭配的

1.hadn't cooperated
这一句是虚拟语气，意思是说如果他们不合作，我们的计划就会失败。从句应该用过去完成时。
2.making已经有人解释了
3.to do
