Grammar - Past Tense

SIMPLE PAST TENSE

         Para exprimir uma ação que aconteceu num momento definido no passado, usamos o Siple Past Tense de verbos regulares na forma afirmativa acrescentando-se ED ao infinitivo sem a partícula TO.

Ex.: She worked yeste rday

         No Simple Past Tense, a forma do verbo é a mesma para todas as pessoas, inclusive para a 3ª pessoa do singular (he, she, it). Observe a conjugação do verbo TO WORK (trabalhar) no Simple Past Tense, na forma afirmativa:

I worked

You worked

He worked

She worked

IT worked

We worked

You worked

They worked

FORMA INTERROGATIVA

         Para se fazer perguntas no Simple Past Tense, usamos o auxiliar DID no começo da frase e o verbo principal volta ao infinitivo sem a partícula TO. Lembre-se de substituir o ponto final pelo ponto de interrogação.

Ex.: Did you work yesterday?

DID não tem qualquer significado. É um auxiliar da forma interrogativa. Tem forma única para todas as pessoas.

TO WORK

Did I work?

Did You work?

Did He work?

Did She work?

Did IT work?

Did We work?

Did You work?

Did They work?

FORMA NEGATIVA

         A forma negativa é feita colocando-se DID NOT entre o sujeito e o verbo, o qual volta à forma do infinitivo sem a partícula TO. A forma contrata de DID NOT é DIDN’T para todas as pessoas.

TO WORK

I did not work (I didn’t work)

You did not work (You didn’t work)

He did not work (He didn’t work)

She did not work (She didn’t work)

IT did not work (IT didn’t work)

We did not work (We didn’t work)

You did not work (You didn’t work)

They  did not work (They didn’t work)

         Casos especiais de alguns verbos regulares no Simple Present Tense.

         Há dois casos em que os verbos regulares sofrem transformações na grafia quando se acrescento a grafia ed. Esses casos são:

1.            Quando o verbo termina em e, acrescenta-se somente o d.

      Ex: to dance – danced

            to decide – decided

2. Quando o verbo termina em Y, precedido de consoante, troca-se o Y por i e acrescenta-se  ed.

Ex.: to study – studied

         To try – tried

Obs: Quando o y é precedido de vogal, acrescenta-se ed.

Ex.: to play – played
