Past Simple: глагол в начальной форме становится глаголом в времени. Для неправильных глаголов (исключений) нужно учить две формы времени.
Например: come --> came (не comed!). Эти формы лучше знать наизусть.
Для правильных: глагол + окончание ed, например:
время глагола "работать".
Здесь же, изменяется форма глагола be ("быть") для второго числа, единственного и множественного чисел.
Ед.ч. : is / isn't (is not), am;
Мн.ч.: are / aren't (are not).
В времени:
is --> was
isn't --> wasn't
are --> were
aren't --> weren't
am --> were и was
