Answer 1

Os verbos regulares em ingles tem sua terminação em D u ED, ja os verbos irregulares tem sua terminação diferente destas, então para voce encontrar os irregulares basta observar a sua terminação. 
Ex = Was = Não tem sua terminação em Ed então ele é um verbo irregular.
Ex= Starred = Tem terminação em Ed, Etão é um verbo regular.
Espero ter ajudado. ^-^
