Question

It is requested by the manager of the hotel that radios _________ after 11 o’clock at night．

[　　]

A．

were not played

B．

not be played

C．

not to play

D．

did not play

Answer 1

答案：B
解析：

题意是“旅馆老板恳请客人晚上11点后不要打开收音机”。谓语动词request后的宾语从句应当用虚拟语气，即“should＋动词原形”，should可以省略。从句radio和play是动宾关系，谓语动词用被动语态，排除C和D项。
