Sure! Here are the sentences rewritten in their negative and interrogative forms:
1. Sophie does not brush her teeth three times a day.
Does Sophie brush her teeth three times a day?
2. She does not go to school by bus.
Does she go to school by bus?
3. She does not listen to music.
Does she listen to music?
4. She does not chat with her parents for a while.
Does she chat with her parents for a while?
Remember, when forming negative sentences, we add "not" after the auxiliary verb (e.g., does not, do not). For interrogative sentences, we switch the subject and the auxiliary verb in English.
