what is necessary/ what is it necessary...

I found that when I turn the sentence (it is necessary for us to do exercise everyday) into a Interrogative Sentence by following the grammatical rule, it should be like this:

=What is "it" necessary for us to do everyday? (But I think the sentence seems odd to me by containing "it".)

=What is necessary for us to do everyday? (It sounds more natural to me)

Which one is grammatically correct? why?

Belinda Chen =What is necessary for us to do everyday? " The dummy subject "it" is not needed for syntactical purposes, so we don't use it. English has two dummy pronoun subjects - there and it.

The subject is "what." The dummy subject "it" is not needed for syntactical purposes, so we don't use it.

English has two dummy pronoun subjects - there and it.

Thanks for the reply and sharing the link.

That is to say:

Take another example:

"It is important to know the information" should be turn into:

*What is important to know?"

But not "what is it important to know"

is that right?

Even if it seems odd to you, it is correct.

Also OK. There is no requirement to change to a shorter form when it's a que

Thank you for the reply. Then if "what is it necessary to do everday?" Is correct:

How about turning "it is good to eat apples" into:

*What fruit is it good to eat?
*We know what fruit it is good to eat.

are the two sentences correct?

Belinda ChenHow about turning "it is good to eat apples" into:*What fruit is it good to eat?*We know what fruit it is good to eat.are the two sentences correct?
Yes. They are both correct. The direct question (your first example) is not very unusual, but the use of the dummy 'it' in the indirect question (your second example) is less often heard.
