It was recommended that they ( ) for the doctor.A.has waited B.waited C.wait D.
It was recommended that they ( ) for the doctor.
A.has waited B.waited
C.wait D.should have waited
我选C,不是说这种句型后面应该是(should) do嘛
为什么阿
It was recommended that they ( ) for the doctor.A.has waited B.waited C.wait D.It was recommended that they ( ) for the doctor.A.has waited B.waitedC.wait D.should have waited我选C,不是说这种句型后面应该是(should) do嘛为什么
这个句子的确是虚拟语气.但是should do中的do是很多学生口中的“动词原形”,其实在语法理论上是省略了to的不定式,而不定式的基本形式是to do,但是也有形式的变化.to have done 就是不定式的完成式,表示不定式的这个动作发生在句子中谓语动词之前.
而你做的这个题,从句意上看,wait这个动作应该是发生在recommend这个动作之前的.在建议给出的时候,等候这个动作已经结束了.强调先后顺序,所以是D
多说一句,一般搭配中的to do都可以根据句意,变形为to be done (不定式的被动式)to have done(不定式的完成式),to be doing(不定式的进行式)
因为前面是was
如果是is的话,就用 (should) wait
现在是was,时态要再往前
就用D
望采纳
