Tenses - Past tense

Past tense

Grammar Focus

Past tense verbs usually end with an -ed ending but only for affirmative sentences. For questions and negative statements we use did to express the past. See below.

(Q) Where did you work?
(A) I worked in an office.
(N) I did not work in the city.

There are three ways to pronounce the -ed ending.

-ed = /t/

I washed the dishes
I walked to work.
I worked at my desk.
I talked to my friend

-ed = /d/

I cleaned the room.
I enjoyed the movie.
I mowed the lawn.

-ed = /id/

I wanted to go.
I decided to stay.
I needed to sleep.

Negative

I did not work.
I didn’t sleep much.

(do not = didn’t)
