1、当to 是介词是,后跟动词要用ing形式
(1) admit to doing sth. 承认做了某事
(2) apply to doing sth. 适用于做某事
(3) object to doing sth. 反对做某事
(4) see to doing sth. 负责做某事
(5) stick to doing sth. 坚持做某事
2、当to 是不定式符号时,后用动词原形
(1) I don't want to leave, but I can't go on.
我不想离开,但我继续不下去了。
(2) I want to have a talk with him alone.
我要和他单独谈一谈。
(3) I don't want to hurry you.
to 可以是介词,也可以是结构助词。作介词用的时候,后面跟名词或动名词,比如:give the book to Tom. i am looking forward to seeing you. 至于什么时候用to,介词的用法都是固定搭配的,与其记住很容易混淆的多种含义,不如直接背固定词组。
1、to后面接动词原形,构成动词不定式,to后面还可以接动名词,这时to作介系词来使用。
2、动词不定式是动词的一种非限定形式,由to加动词原形构成,在句中起名词、形容词和副词的作用,同时也保留动词的一些特征,可以带宾语、状语和宾语补足语等。
