simple past tense theory

1. Simple past,form


Regular verbs: base+ed
e.g. walked, showed, watched, played, smiled, stopped

Irregular verbs: went, came, bought, etc.



Simple Past: be, have, do:

Subject	Verb
	Be	Have	Do
I	was	had	did
You	were	had	did
He,she, it	was	had	did
We	were	had	did
You	were	had	did
They	were	had	did

Affirmative

1. I was in Japan last year
2. She had a headache yesterday.
3. We did our homework last night.

Negative and interrogative

Note:
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”.

• They weren’t in Rio last summer.
• We hadn’t 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 a boy?

2. Simple past, function
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.

• 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
Examples:

• frequency:often,sometimes, always;
• a definite point in time:last week, when I was a child, yesterday, six weeks ago.
• an indefinite point in time:the other day, ages ago, a long time ago etc.

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

Examples:
a. Yesterday, I arrived in Geneva.
b. She finished her work at seven o’clock.
c. We saw a good film last week.
d. I went to the theatre last night.
e. She played the piano when she was a child.
f. He sent me a letter six months ago.
g. Peter left five minutes ago.
