问题
选择题
________ anyone come to my office, please tell them I'm not available before four o’clock.
A.Might
B.Could
C.Would
D.Should
答案
D
题目分析: 句意:如果有人来到我的办公室,请告诉他们在4点前我不在。这里用的是if虚拟语气的省略倒装,if anyone should come to my office,表示假设,这种虚拟条件句可以省略if,将should提前,其他几个情态动词might可能,could能够,would将会,都不能用于虚拟条件句,所以选D。
