问题描述：
He ______ sing English songs.
A.is often heard to B.is often heard C.often hears D.is often hering 选哪个?为什么?句子意思是?
答
B经常听到他唱英文歌曲。
这里是被动语态。
答
A 是正确的，意思是经常有人听到他唱英文歌。因为hear sb do sth 省略 to,变为被动语态时to 要加回来，
答
a
答
A
据说他唱英文歌
sb is heard to do sth 据说某人干某事
答
A
sb be heard to do 这是被动的形式
(区别与hear sb do sth 这是主动的）
(hear感官动词用作被动语态中务必要加to)
答
B
被动语态，使用be done形式
hear是及物动词，不用加to
