It is time that you ____to make the final decision on this matter.
A.helped B.should help
答案a
请帮忙讲解下

此句考的为固定句型的用法
it‘s time that sb did/had done
表现在或将来用did 表过去用had done

虚拟语气,行为动词用过去式.

B

it is time to do sth
所以后面跟的 that you ···是定语修饰前面的话
所以应该填 that you helped
B选项应该填 should be helped ,should be 省略
