He heard someone singing in the next room.请问这里的宾补sing为什么加的是ing?而不是ed或者是不定式?按道理来说,前面heard用过去式,后面sing也要用过去式啊?到底宾补在什么状态下要用什么式?

是这样的：
sing在这是感官动词,也就是联系动词,有一个固定的句型：
连系动词+do或doing
所以,不定式啊,过去时啊,都不可以用
而+do 和doing的区别在于
do表示经常干某事,或者是一瞬间的动作,这个动作在刚才刚刚完成
例：I often hear him sing at night.我经常在晚上听见他唱歌.
Someone drop the monry just now.刚刚有人的钱掉在地上了.
Someone saw her walk into the building.刚有人看见她走进了大楼.
而doing表示正在做或偶然在做一件什么事情
例：I heard someone singing last night.昨晚我听见谁在唱歌.（唱歌是可持续动作,故不用原形）
I saw mum cooking when I got home yesterday.昨天我回家的时候正好看见妈妈在做饭.
总之,先理解句子的意思,再判断,用do或doing

He heard someone singing in the next room.请问这里的宾补sing为什么加的是i I heard someone sing in the next room. 为什么用 sing 适当形式填空 I heard him （）(sing)in the next room.答案写的是sing,但为什么不 I heard her___ in the next room just now.A sing B singing I heard him ____ in the next room just now.A.singing B.sing I heard someone( )in the next room last night. A.singing B.s I heard someone sing in the next room last night.语法有误吗? I often hear her sing songs in English in her room.这里的宾补为什么是 I heard he was singing in the next room.I heard —— ——in the we often heard her sing in the next room 为什么动词不是ing形式的? I heard Amy singing in the next room just now I heard he was singing in the next room.是什么从句?
