Question

My father worked day and night. Otherwise, there ________ no one to support the family.

A．would be

B．must be

C．would have been

D．must have been

Answer 1

C

試題分析：從信息詞 Otherwise可以看出是一個(gè)含蓄條件句，再?gòu)膭?dòng)詞worked 可以看出是與過(guò)去相反，故主句使用would have been。本句可以改寫為if引導(dǎo)的條件狀語(yǔ)從句：if my father hadn’t worded day  and night,there would have been no one to support the family.
點(diǎn)評(píng)：含蓄條件句將條件隱含在某些連詞(如or, or else, otherwise等)中。還有將條件隱含在介詞短語(yǔ)中（如with ,without,but for等）。
