高中英语动词不定式问题一个句子当中,怎么判断不用不定式还是用不定式啊?加了to和没加to有什么意义吗?

1个回答

  • 不定式to do是动词的一种非谓语形式.在句子中有需要时一定要用,如一些及物动词后用作宾语.不及物动词后用作状语,系动词后用作表语,还可作主语,补语,如

    I want to go there.

    He came to see me .

    My task this afternoon is to clean my room.

    To see is to believe.

    Our teacher told us to recite all the new words.

    在使役动词和感观动词后用不带to的不定式作补语,如

    Let's play.

    I often hear him sing this song.

    They made the workers work ten hours a day.

    但被动语态中一定带to,如

    The workers were made to work ten hours a day.
