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。
