—________ one and a half months enough for the project to be finished?
—I am afraid not.The professor is ill and only after he recovers ________ go on with it.

A．Is；he can	B．Are；he can
C．Is；can he	D．Are；can he

答案

C

解析

由主语one and a half months可知，谓语动词应该用单数，将其看成一个整体，所以第一空用is；第二空and连接的并列句的第二句是only位于句首，应该用部分倒装，所以用can he，故C项正确。句意为：——一个半月的时间可以完成这个项目吗？——我觉得恐怕不够，教授生病了，只有等他康复之后才能继续工作。
