Question

The teacher demanded that the exam _____ before eleven.

A．must finish

B．would be finished

C．be finished

D．must be finished

Answer 1

C

解析試題分析：demand要求，后接賓語從句，從句要用should + do,should可省略。故選C
考點：虛擬語氣
點評：demand, insist, suggest, command, order, require, request, desire等一類動詞后的賓語從句（suggest表“暗示、隱含等”insist表“強調(diào)，力言等”不用虛擬語氣。） 從句謂語用“should+動詞原形”，should可省。
