Where did you go last night?
Здесь нужен Past Simple (вопрос о завершённом действии в прошлом: last night). В вопросе используем вспомогательный did + начальную форму глагола go.

My father didn’t want to be a teacher when he was young.
Отрицание в Past Simple: didn’t + начальная форма want. Подсказка — when he was young (прошлое).

I didn’t use to like walking in the mountains but now I love it.
Конструкция привычки в прошлом: used to. В отрицании чаще всего: didn’t use to + глагол. Поэтому: didn’t use to like.

They were playing tennis when it started snowing.
Два действия в прошлом: длительное (фон) + короткое (внезапное). Фоновое — Past Continuous: were playing, а короткое уже дано: started.

If you don’t drive more carefully, you’ll have an accident.
Это First Conditional (реальная ситуация в будущем):
в части с if — Present Simple (don’t drive), в главной — will (you’ll have).

Hello! Sorry, I can’t talk now. I am having dinner.
Слово now → действие происходит прямо сейчас, значит Present Continuous: am having.

Oh, no! I didn’t give Anna a present for her birthday yesterday.
Yesterday → Past Simple. Отрицание: didn’t + начальная форма give.

She won’t pass her exams if she doesn’t work harder.
Снова First Conditional: результат в будущем — will not → won’t pass. В if-части уже стоит doesn’t work (Present Simple).

Do you think cars will fly in the future?
In the future и прогноз/мнение → Future Simple: will fly.
