回答1:

to 有两种用法: 一为不定式+动词原形; 一为介词+名词/动名词, to 在下面的用法中是第二种,即to+ 名词/动名词:
但也有好多短语固定搭配 to + V-ing. 比如 look forward to + v-ing, pay attention to 等等

回答2:

to作介词是后面加ing 其余的后面就是动词原形

回答3:

to作为动词不定式的标志的时候 后面接do
to作为介词的时候 后接doing 只要记住接doing 的情况就可以了
look forward to doing
be used to doing
get down to doing
lead to doing
as to doing
prefer doing to doing
lead to
object to
