问题描述：
The decision___,what we should do now is to carry it out.
A.been made B.has been made
C.having been made D.having been making.
这题为什么选C啊?
答
因为要去做状语，只能是having been done的形式，而且决定应该是人发出的，是被动
答
首先要知道这道题的空白处填谓语动词还是非谓语.如果是谓语动词的话,那么前后两句话应该有and but 等连词来引导.由于此处没有.所以选非谓语.排除B .要知道The decision 和make是被动关系排除D .又做决定这个动作时发生在should do now 之前所以用完成时
