Question

【题目】________ anyone come to my office, please tell them I'm not available before four o’clock.

A. Might B. Could

C. Would D. Should

Answer 1

【答案】D

【解析】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。
