5.
2. didn't go   (к глаголу прош. времени Did добавляем not)
3. didn't sing  (к глаголу прош. времени Did добавляем not)
4. fought      (Я поставила глагол во вторую форму)
5. helped     (Добавляем окончание прошедшего времени ed)
6. baked       (Добавляем окончание прошедшего времени ed)
7. Did Sam enjoy  (на первое место выносим вспомогательный глагол Did,  основной глагол enjoy не изменяем)
8. fell and hurt  ( Ставлю оба слова во вторую форму глагола (у слова hurt все три формы одинаковые, чтобы Вас не смущало))
