He is often heard _____ in the next room.A.singing B.sang C.to singing D.to sing 为什么答案是A而不时D呢?hear sb do sth变成被动语态后,do sth前面不是要加上to
hear+to do ,强调的是动作的结果,也就是sing 的结果
hear+doing,强调的是动作的状态,也就是sing这个状态,本句意思是：人们经常听到他在隔壁唱歌,强调的是他唱歌这个状态,而没有说他唱歌的结果,所以选A不是D
这是高中常做的题,

选A singing 因为唱歌是一种状态，而不是要去做某事（to do）。
人们常听到他在隔壁唱歌。
而不是：人们常听到他在隔壁要去唱歌。

hear sb do sth (hear后跟不带to的不定式做宾补）

你也说了是hear sb do sth，而不是hear sb doing sth啊
hear sb do sth变成被动语态后,do sth前面加上to是因为之前省略了to
但doing之前没有省略to,所以也不用加

语感…
