Transformation of Assertive to Interrogative sentence –

1 . If an auxiliary verb exists after the subject in an assertive sentence then the verb will be used at the beginning of the sentence and not or n’t  will be used after the auxiliary verb to transform to an interrogative sentence.

Examples – He is a good boy.
  Isn’t he a good boy ?

She will come to my house tomorrow.
Won’t she come to my house tomorrow?

The boy can do this .
Can’t the boy do this ?


2. If an auxiliary verb exists in a negative sentence then to transform the sentence to an interrogative sentence, the verb is used at the beginning of the sentence and the negative word or not or n’t disappears.

Examples – He is not a busy man.
Is he a busy man?

She can’t neglect it.
Can she neglect it ?



3. If there is no auxiliary verb in an assertive sentence then to transform the sentence to an interrogative one we need to use don’t / doesn’t / didn’t attend the beginning of the sentence.

Examples – She draws really well.
Doesn’t she draw really well ?

He played great yesterday.
Didn’t he play great football?

They perform really well.
Don’t they perform really well?





4. If the subject of an assertive sentence is ‘nothing’ then it turns to ‘what’ to transform the sentence to an interrogative sentence.

Example – Nothing can be done now .
What can be done now ?

Nothing was possible for them .
What was possible for them ?



5. If there is ‘nothing’ in an assertive sentence then it turns to ‘anything’ to transform the sentence to an interrogative sentence.

Example -The boy has nothing to do.
Does the boy have anything to do ?

He had nothing to do .
Did he have anything to do?




6. If there is ‘never’ in an assertive sentence then it turns to ‘ever’ to transform the sentence to an interrogative sentence.

Example – He never played football?
Did he ever play football?



7. If there is nobody/ no one / none in an assertive sentence then it turns to ‘who’ to transform the sentence to an interrogative sentence.

Examples –
Nobody can help you now.
Who can help you now ?

No one will be present there .
Who will be present there ?

None is assisting him .
Who is assisting him ?



8. If there is everybody / everyone / all in an assertive sentence then to transform the sentence to an interrogative sentence we need to use ‘who’ instead of everybody / everyone / all .

Also we use don’t / doesn’t / didn’t as per the subject and tense if there is no auxiliary verb.

If an auxiliary verb exists in the assertive sentence then we use not or n’t after the auxiliary verb .

Examples –

Everybody joined the meeting.
Who didn’t join the meeting?

Everyone likes to be there.
Who doesn’t like to be there ?


All were present there .
Who wasn’t present there?
