It is politely requested by the hotel management that radios ____ after 11 o'clock at night .
A. were not played
B. not be played
C. not to play
D. did not play
题目解答
答案
B. not be played
解析
本题考查虚拟语气的用法,特别是It is requested that...结构中的虚拟语气形式。关键点在于:
- 主句中的动词是request的被动形式(is requested),此时从句需使用虚拟语气。
- 虚拟语气的结构为should + 动词原形,但在被动结构中,should可以省略,直接使用动词的被动语态形式。
句子结构分析
原句为"It is politely requested by the hotel management that radios ____ after 11 o'clock at night."
- 主句是"It is requested...",其中request的被动形式要求从句使用虚拟语气。
- 从句需表达“收音机不要播放”,因此动词需用被动语态,且符合虚拟语气的结构。
虚拟语气规则
在"It is requested that..."结构中,从句的虚拟语气形式为:
should be done(should可省略,直接用be done)。
本题中,否定形式需在be前加not,即not be played。
选项分析
- A. were not played:使用过去时态,不符合虚拟语气的语境。
- B. not be played:正确形式,符合虚拟语气的被动结构。
- C. not to play:动词不定式结构,与虚拟语气要求的动词原形不符。
- D. did not play:过去式,不符合虚拟语气的结构。
