感官动词的用法 see, hear, listen to, watch, notice等词，后接宾语，再接省略to的动词不定式或ing形式。前者表全过程，后者表正在进行句中有频率词时，以上的词也常跟动词原形。 注释:省略to的动词不定式to do是动词不定式，省略了to,剩下do，其形式和动词原形是一样的，但说法不同。see sb do sth 看到某人做了某事see sb doing sth 看到某人在做某事hear sb do sth 听到某人做了某事hear sb doing sth 听到某人在做某事以此类推... I heard someone knocking at the door when I fel asleep. (当时正在敲门)I heard someone knock at the door three times. (敲门的全过程)I often watch my classmates play volleyball after school. (此处often) 若以上词用于被动语态，须将省略的to还原：see sb do sth ---- sb be seen to do sthhear sb do sth ---- sb be seen to do sth以此类推...
