Is everything________we need to_______?

题目

Is everything________we need to_______?
Yes.You needn't worry about it.
A.which;has done B.which；doing
C.that；has done D.that;done
为什么这题选择D?A或者C哪里错了?
题目应该改为：
Is everything________we need to do _______?
Yes.You needn't worry about it.
A.which;has done B.which；doing
C.that；has done D.that;done

答案

不定代词everything后面只能跟that,排除A,B.事情是被做的,问题是“是不是我们需要做的每件事都做了”,用被动done ,has done是现在完成时,被动是has been done
