2）I saw him cross the street.上述动词接不定式省略了___？to作宾语补足语不带to 的情况：常见动词有：?使役动词: let, make, have
感官动词: see, watch, notice，hear, feel如：老板让工人们整天都工作。
The boss made the workers______
all day.但这些词在被动语态里要还原to如：I saw him play football yesterday.
He was seen _________football
yesterday.workto play昨天我看见他踢足球。比较：
1）I heard her sing in the next room.
2）I heard her singing in the next room.
感官动词后既可跟不带to的不定式 作宾补，也可跟动名词作宾补，前者表示动作的全部过程已结束；后者表示动作正在进行。以上两句有什么不同？1.John was made the car for a week as a punishment
A. to wash B. washing C. wash

My job is to help the patient.不定式作表语常放在____动词之后。be6. 作表语 7. 疑问词 + 不定式不定式与疑问词who,which,when, how,what,where等连用，在句中起名词作用，可充当主语、表语、宾语等。☆在与why连用时，后面紧跟的动词不定式不带to。
