• Declarative sentences can be changed into interrogative ones by addition of a question tag at the end of it.
• There is a simple rule for addition of question tags- Affirmative or positive statements are followed by negative tags whereas negative sentences are followed by positive tags.
• The question tags are in accordance with the verb and subject used in the sentence.

1. You love grapes. Don't you?
2. She does not like him. Does she?
