请问一语法基本点：不定式与介词+动名词

介词后必须加动名词。 I have no objection to hearing your story again.   (摘自牛津语法）

可不定式不就是to do 的形式吗？ 如何区分呢？

请牛牛门解答。

哎，书看了一半就问。

区别to是介词还是动名词一部分的好办法就是看它后面能否放置一个名词或代词。能放的就是介词。

object to doing

不要管为什么，记住就好了，类似的还有几个

resort to doing

look forward to doing

accustom to doing

dedicate to doing

devote to doing

use to doing

with a view to doing

prior to doing
