Question

—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

由主語one and a half months可知，謂語動(dòng)詞應(yīng)該用單數(shù)，將其看成一個(gè)整體，所以第一空用is；第二空and連接的并列句的第二句是only位于句首，應(yīng)該用部分倒裝，所以用can he，故C項(xiàng)正確。句意為：——一個(gè)半月的時(shí)間可以完成這個(gè)項(xiàng)目嗎？——我覺得恐怕不夠，教授生病了，只有等他康復(fù)之后才能繼續(xù)工作。
