Answer 1

It 's no use____ much but ____ little.
A， saying ， doing B, to say ， to do
常接的是ing形式， 但是我感觉不定式也行啊？
为什么呢？
答：你感觉不定式行，说明你对这个句型还不了解: It is no use/ good doing sth.
这来源于一个典故，一个谚语：It is no use crying over spilt milk. 牛奶洒了，哭也没用。
常见的是It is +adj. +to do sth. 如it is important to do sth. 甚至It is +n. + to do sth. 如It is good manners to greet teachers. It is bad manners to speak with one's mouth full.

Answer 2

It 's no use（in）doing sth.
介词之后

Answer 3

固定用法

Answer 4
