【—辅导之感官动词一】下面是对感官动词用法之一的讲解，同学们做好笔记工作。

　　感官动词用法之一：

　　see, hear, listen to, watch, notice等词，后接宾语，再接动词原形或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。

　　I heard someone knocking at the door when I fell asleep. (我入睡时有人正敲门)

　　I heard someone knock at the door three times. (听的是全过程)

　　I often watch my classmates play volleyball after school. (此处有频率词often)

　　若以上词用于被动语态，后面原有动词原形改为带to不定式：

　　We saw him go into the restaurant. → He was seen to go into the restaurant.

　　I hear the boy cry every day. → The boy is heard to cry every day.

　　希望老师上面的讲解能很好的帮助同学们对感官动词用法之一的掌握，后面我们接着学习感官动词用法之二的知识。
