Решение:
II. Добавим тег-вопросы к предложениям:
- They haven't come, have they? (Отрицательное вспомогательное глагол haven't -> has, подлежащее They).
- Jenny can't drive, can she? (Отрицательный вспомогательный глагол can't -> can, подлежащее Jenny -> she).
- Marie's French, isn't she? (Marie's = Marie is. Форма глагола 'to be' + подлежащее Marie -> she).
- I'm late, aren't I? (I am -> aren't I? - стандартное исключение).
- You work here, don't you? (Вспомогательный глагол do/does. You work -> do, подлежащее You).
Ответ: have they?; can she?; isn't she?; aren't I?; don't you?
