连接词+不定式结构（Wh-+Infinitive)。有时，不定式的前面可以有一个连接词、连接代词或连接副词（包括 whether，what, which, whom, where, when, how)。不定式的这种结构在句中主要起宾语作用，也可作主语和表语。例如：
He will tell us how to use the library. 他将告诉我们如何使用图书馆。
Where to get the book is what I want to know. 在什么地方能搞到这本书是我想知道的事情。
The problem is whether to go on with the experiment. 问题是是否要继续进行这个试验。
为您解答
不是，大部分都不加。只有疑问词+to的特殊结构才加（这个结构都不能算句子）
比如
How to go there?
What to do?
疑问词（why 和if 除外）+不定式to do 是不定式复合短语，在句子中作主语、宾语、表语。如：I know when to go. What to do next isn't clear. My question is where to live.
不是
有些疑问词后不能加to
