Explanation:
Changing into negative form is very easy we just have to change the verb of the given sentence in to negative form like 'are as aren't; is as isn't; has been to hasn't been' etc., we just have to add not to the verb given in the sentence.
There are few rules for changing sentences to interrogative form.
1. Sentence is in affirmative, change it into negative interrogative. If sentence is in negative then change it in to positive.
2.If there is no verb then we have to use do, does, did, don't, doesn't, didn't in the interrogative sentence.
3.Always move the helping verb to first position while changing to interrogative form.
