Question

It's fun to watch the elephant draw a picture.中draw为什么不加s

Answer 1

感官动词后接现在分词或【动词圆形】

2.感官动词作不完全及物动词时,后接宾语,再接动词原形或分词作宾语补语.

But I really heard someone steal.

但我真听见有人在偷东西.

I heard her sing.

我听见她唱歌.

感官动词后接动词原形强调事实. I heard someone opening the cabinet.

我听见有人在开柜子.

I heard her singing.

我听见有人在唱歌.

感官动词后接现在分词强调动作正在进行.
