I hope to find an answer to my question.
The question is: what is the difference between theses questions? what is reading? what reading is?

As bhaisahab said, "What reading is?" is incorrect. Your first sentence is the correct construction of a sentence.
Also note the correct spelling of "difference".
I believe you could use these:
What is reading?
Do you know what reading is?
