Though i have often heard this song( ),i have never heard you ( ) it.A.being sung;s Though i hav

Though i have often heard this song( ),i have never heard you ( ) it.A.being sung;s Though i hav

hear后的三种用法：
hear sb do sth 听见某人做某事
hear sb doing sth 听见某人正在做...
hear sb done 听见某人被....
第一个空是听见歌被唱，所以用done过去分词，第二个空就是描述一般情况用do一般现在时

虽然我经常听到这首歌（），我还从未听过你唱的it.a.being（）；虽然我经常听到这首歌（），我还从未听过你（）它。尽管唱；唱Bsang；唱c.sung；唱：唱；唱

句子是完成时态，表示听过，而D答案的to 不定式表示将来。前一个hear的宾语是this song, 歌是被唱，所以用过去分词sung, 而第二个hear的宾语是you，人是动作的发出者，所以用sing.追问可是不是有一个感官动词主省被还的用法吗？被动式用还原to的不定式表被动 我混了

因为第二空不是被动语态， 如果是被动语态才需要to, 例如：
I heard her sing a song.
She was heard to sing a song.
所以D不能加to，因为不是被动语态。
