Question

—________ 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

 

Answer 1

C

【解析】C 考察主謂一致和倒裝句。句中主語one and a half months作為一個整體，表示時間，因此謂語部分使用單數形式，排除BD，only+狀語 放在句首，后面要使用部分倒裝的形式。故C正確。
