專家輔導(dǎo)英語六級語法之虛擬語氣(3)

例題分析：

15.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

全句意思是：“旅館管理部門懇請客人晚上11點后不要打開收音機”。句中的謂語動詞request（請求）所引出的從句應(yīng)當(dāng)用虛擬語氣，即動詞原形或“should+動詞原形”。本句的主語從句中，主語radio是謂語動詞play 的客體，謂語應(yīng)當(dāng)用被動語態(tài)。所以，答案是C） not be played。在上述這類句子中不能用動詞過去時形式表示虛擬語氣，所以A）不正確。選項B） not to play是動詞帶to的不定式，不能在句中作謂語。選項D）did not play也是動詞play的過去時形式，同樣不能在本句中作為虛擬語氣來使用。而且，它是主動語態(tài)形式，而本題要用被動語態(tài)。
