Answer:
1. Are we going to a rock concert tonight?
2. My friend Amy isn't going to the parade.
3. We are setting off fireworks tonight.
4. Paul is having a graduation party.
5. Are you going to the party?
Step-by-step explanation:
To turn a positive sentence into a negative one, we have to add the word not next to the verb to be. For example, in the sentence My friend Amy is going to the parade, we add not after the is. As a result, we have My friend Amy is not going to the parade. Also, we can use the contraction isn't.
To make questions, we invert the order between the auxiliary verb and the subject. The order would be auxiliary verb+ subject+ verb+ the rest of the question. In the sentence "we are going to a rock concert tonight." We move the auxiliary verb "are" to the beginning of the sentence, and then it follows the subject we.
To make a positive sentence from a negative one, we only have to remove the not or the contraction isn't/arent and replace it by is/are. For example, in the sentence we aren't setting fireworks tonight, we have to replace aren't with are.
