Changing an interrogative sentence into an assertive sentence and vice versa

An assertive sentence can be changed into an interrogative sentence by putting the auxiliary verb before the subject.

Assertive: She is my friend.
Interrogative: Is she my friend?

Assertive: He has finished his work.
Interrogative: Has he finished his work?

Assertive: He is very intelligent.
Interrogative: Is he very intelligent?

Notes

If the assertive sentence contains the adverb never, it becomes ever in the interrogative sentence.

Assertive: I never asked you to do it.
Interrogative: Did I ever ask you to do it?

If the assertive sentence contains the adverb no, it becomes any in the interrogative sentence.

Assertive: There is no sense in doing that.
Interrogative: Is there any sense in doing that?

Interrogative: Will you stop it?

Imperative: Please, give me a glass of water.

Note that the interrogative is a milder form of the imperative. But the addition of ‘or not’ to the interrogative form will add a touch of threat to it.

Interrogative: Will you shut up or not?

Imperative: Get out of here.
Interrogative: Will you get out of here or not?

Imperative: Speak loudly.
Interrogative: Will you speak loudly?
