PAST SIMPLE 
FORMA AFIRMATIVA

Los verbos regulares forman el pasado en forma afirmativa añadiendo -ed al infinitivo:

• Play > played
• Work > worked

Los verbos irregulares no añaden -ed. Tienen su propia forma

• Be > was / were
• Do > did
• Make > made

FORMA NEGATIVA

Tanto los verbos regulares como los irregulares forman la negativa del pasado poniendo
did not (didn´t) delante del infinitivo sin to.

     I did not play football yesterday          I didn´t play football yesterday
     I did not work yesterday                    I didn´t work yesterday

FORMA INTERROGATIVA

Para hacer una pregunta en pasado usamos la siguiente estructura: did + sujeto + verbo

     Did you play football yesterday?
     Did you work yesterday?


Reglas ortográficas:

• Con la mayoría de los verbos añadimos una -ed al infinitivo.
  work > worked
  
• Si el infinitivo acaba en -e, solamente añadimos una -d.
  live > lived
  
• Si el infinitivo acaba en consonante + y, cambiamos la -y por -i y añadimos una -ed:
  try > tried
  
• Los verbos monosílabos que acaban en vocal + consonante (excepto w o y)", duplican la consonante final al añadir la -ed:
  stop > stopped
  plan > planned

USO DEL PAST SIMPLEUsamos el Past Simple para hablar de acciones y situaciones que sucedieron en un momento concreto del pasado y que por tanto, ya están acabadas.

   I played football yesterday
   I did my homework two hours ago
   We went to London last year
   My father didn´t work last Monday
Expresiones temporales de pasado

• yesterday
• last week
• last year
• etc...
