如何区分介词to和不定式to，赶紧收藏！

最近被one step closer to doing还是one step closer to do难住了。今天就和大家分享一下如何区分介词to和不定式to。

一般来说to后接动词原形时，为不定式to。例如：

intend to do

ask to do

try one’s best to do

wish to do

want to do

decide to do

apply to do

afford to do

happen to do

to后接名词或动词现在分词ing时，为介词to。例如：

admit to doing

confess to doing

be accustomed to doing

be used to doing

stick to doing

turn to doing

be devoted to doing

look forward to doing

pay attention to doing

知道上面这一点并不难，但是如何在具体的使用过程中进行判断呢?

方法很简单，能加名词的就是介词，不能加名词的就是不定式。所以常见的look forward to/.devoted oneself to/be addicted to/be reduced to/ be sentenced to里面的to就是介词，后面加动词的话就需要V-ing。

所以，究竟是one step closer to doing还是one step closer to do？聪明的你一定有了答案。
