    SIMPLE PAST TENSE

     

    FUNCTIONS OF THE SIMPLE PAST TENSE

    The simple past is used to talk about a completed action in a time before now. Duration is not important. The time of the action can be in the recent past or the distant past.

    EXAMPLES
    • John Cabot sailed to America in 1498.
    • My father died last year.
    • He lived in Fiji in 1976.
    • We crossed the Channel yesterday.

    You always use the simple past when you say when something happened, so it is associated with certain past time expressions

    • frequencyoften, sometimes, always
      I sometimes walked home at lunchtime.
      I often brought my lunch to school.
    • a definite point in timelast week, when I was a child, yesterday, six weeks ago
      We saw a good film last week.
      Yesterday, I arrived in Geneva.
      She finished her work atseven o'clock
      went to the theatre last night 
    • an indefinite point in timethe other day, ages ago, a long time ago People lived in caves a long time ago.
    • She played the piano when she was a child.

    Note: the word ago is a useful way of expressing the distance into the past. It is placed after the period of time: a week ago, three years ago, a minute ago.

    Be Careful: The simple past in English may look like a tense in your own language, but the meaning may be different.

    NOTES ON AFFIRMATIVE, NEGATIVE, & INTERROGATIVE FORMS

    AFFIRMATIVE

    The affirmative of the simple past tense is simple.

    • was in Japan last year
    • She had a headache yesterday.
    • We did our homework last night.
    NEGATIVE AND INTERROGATIVE

    For the negative and interrogative simple past form of "do" as an ordinary verb, use the auxiliary "do", e.g. We didn't do our homework last night.
    The negative of "have" in the simple past is usually formed using the auxiliary "do", but sometimes by simply adding not or the contraction "n't".

    The interrogative form of "have" in the simple past normally uses the auxiliary "do".

    EXAMPLES
    • They weren't in Rio last summer.
    • We didn't have any money.
    • We didn't have time to visit the Eiffel Tower.
    • We didn't do our exercises this morning.
    • Were they in Iceland last January?
    • Did you have a bicycle when you were young?
    • Did you do much climbing in Switzerland?

    Note: For the negative and interrogative form of all verbs in the simple past, always use the auxiliary 'did''.
