Pest

A forma ativa dos verbos é a que estamos acostumados a usar na língua inglesa até agora, em que o sujeito executa a ação, portanto a frase mostra o que o sujeito está fazendo:

Ex.: John plays the piano. (Está claro quem pratica a ação).

A forma passiva mostra o que acontece com o objeto.

The piano is played. (O fato de importância é o que acontece ao piano, e não quem o toca).
A forma passiva será usada quando o que ocorre com o objeto for mais importante ou quando o sujeito não for importante ou for desconhecido.

Ex.: We were robbed on that street. (Não se sabe quem nos assaltou).
América was discovered in 1492. (Queremos ressaltar o descobrimento e não quem descobriu).

Forma

A forma passiva muda de acordo com o tempo verbal usado na frase de origem, mas o verbo to be sempre será o auxiliar, que será colocado no tempo verbal original seguido do past participle.
