Simple Past Tense

sang
The simple past tense is sometimes called the preterite tense. We can use several tenses to talk about the past, but the simple past tense is the one we use most often.

How do we make the Simple Past Tense?

To make the simple past tense, we use:
  • past form only
    or
  • auxiliary did + base form
Here you can see examples of the past form and base form for irregular verbs and regular verbs:

V1
base
V2
past
V3
past participle

regular verbwork
explode
like
worked
exploded
liked
worked
exploded
liked
The past form for all regular verbs ends in -ed.
irregular verbgo
see
sing
went
saw
sang
gone
seen
sung
The past form for irregular verbs is variable. You need to learn it by heart.

You do not need the past participle form to make the simple past tense. It is shown here for completeness only.
The structure for positive sentences in the simple past tense is:
subject+main verb


past
The structure for negative sentences in the simple past tense is:
subject+auxiliary verb+not+main verb


did


base
The structure for question sentences in the simple past tense is:
auxiliary verb+subject+main verb
did


base
The auxiliary verb did is not conjugated. It is the same for all persons (I did, you did, he did etc). And the base form and past form do not change. Look at these examples with the main verbs go and work:

subjectauxiliary verb
main verb
+I

wentto school.
You

workedvery hard.
-Shedidnotgowith me.
Wedidnotworkyesterday.
?Didyou
goto London?
Didthey
workat home?
Exception! The verb to be is different. We conjugate the verb to be (I was, you were, he/she/it was, we were, they were); and we do not use an auxiliary for negative and question sentences. To make a question, we exchange the subject and verb. Look at these examples:

subjectmain verb

+I, he/she/itwas
here.
You, we, theywere
in London.
-I, he/she/itwasnotthere.
You, we, theywerenothappy.
?WasI, he/she/it
right?
Wereyou, we, they
late?

How do we use the Simple Past Tense?

We use the simple past tense to talk about an action or a situation - an event - in the past. The event can beshort or long.
Here are some short events with the simple past tense:
The car exploded at 9.30am yesterday.
She went to the door.
We did not hear the telephone.
Did you see that car?
pastpresentfuture



The action is in the past.

Here are some long events with the simple past tense:
I lived in Bangkok for 10 years.
The Jurassic period lasted about 62 million years.
We did not sing at the concert.
Did you watch TV last night?
pastpresentfuture



The action is in the past.

Notice that it does not matter how long ago the event is: it can be a few minutes or seconds in the past, or millions of years in the past. Also it does not matter how long the event is. It can be a few milliseconds (car explosion) or millions of years (Jurassic period). We use the simple past tense when:
  • the event is in the past
  • the event is completely finished
  • we say (or understand) the time and/or place of the event
WSM Image
In general, if we say the time or place of the event, we must use the simple past tense; we cannot use the present perfect.
Here are some more examples:
  • lived in that house when I was young.
  • He didn't like the movie.
  • What did you eat for dinner?
  • John drove to London on Monday.
  • Mary did not go to work yesterday.
  • Did you play tennis last week?
  • was at work yesterday.
  • We were not late (for the train).
  • Were you angry?
Note that when we tell a story, we usually use the simple past tense. We may use the past continuous tense to "set the scene", but we almost always use the simple past tense for the action. Look at this example of the beginning of a story:
"The wind was howling around the hotel and the rain was pouring down. It wascold. The door opened and James Bond entered. He took off his coat, whichwas very wet, and ordered a drink at the bar. He sat down in the corner of the lounge and quietly drank his..."

This page shows the use of the simple past tense to talk about past events. But note that there are some other uses for the simple past tense, for example in conditional or ifsentences.

Past Continuous Tense

was singing
The past continuous tense is an important tense in English. We use it to say what we were in the middle of doing at a particular moment in the past.

How do we make the Past Continuous Tense?

The structure of the past continuous tense is:
subject+auxiliary verb BE+main verb

conjugated in simple past tense
present participle
was
were
base + ing
For negative sentences in the past continuous tense, we insert not between the auxiliary verb and main verb. For question sentences, we exchange the subject and auxiliary verb. Look at these example sentences with the past continuous tense:

subjectauxiliary verb
main verb
+Iwas
watchingTV.
+Youwere
workinghard.
-He, she, itwasnothelpingMary.
-Wewerenotjoking.
?Wereyou
beingsilly?
?Werethey
playingfootball?

The spelling rules for adding ing to make the past continuous tense are the same as for the present continuous tense.

How do we use the Past Continuous Tense?

The past continuous tense expresses action at a particular moment in the past. The action started before that moment but has not finished at that moment. For example, yesterday I watched a film on TV. The film started at 7pm and finished at 9pm.
At 8pm yesterday, I was watching TV.
pastpresentfuture

8pm
At 8pm, I was in the middle of watching TV.

When we use the past continuous tense, our listener usually knows or understands what time we are talking about. Look at these examples:
  • was working at 10pm last night.
  • They were not playing football at 9am this morning.
  • What were you doing at 10pm last night?
  • What were you doing when he arrived?
  • She was cooking when I telephoned her.
  • We were having dinner when it started to rain.
  • Ram went home early because it was snowing.

Some verbs cannot be used in continuous/progressive tenses.
We often use the past continuous tense to "set the scene" in stories. We use it to describe the background situation at the moment when the action begins. Often, the story starts with the past continuous tense and then moves into the simple past tense. Here is an example:
" James Bond was driving through town. It was raining. The wind was blowinghard. Nobody was walking in the streets. Suddenly, Bond saw the killer in a telephone box..."

Past Continuous Tense + Simple Past Tense

We often use the past continuous tense with the simple past tense. We use the past continuous tense to express a long action. And we use the simple past tense to express a short action that happens in the middle of the long action. We can join the two ideas with when or while.
In the following example, we have two actions:
  1. long action (watching TV), expressed with past continuous tense
  2. short action (telephoned), expressed with simple past tense
pastpresentfuture
Long action.

I was watching TV at 8pm.

8pm



You telephoned at 8pm.
Short action.

We can join these two actions with when:
  • I was watching TV when you telephoned.
(Notice that "when you telephoned" is also a way of defining the time [8pm].)
We use:
  • when + short action (simple past tense)
  • while + long action (past continuous tense)
There are four basic combinations:

I was walking past the carwhenit exploded.
Whenthe car exploded
I was walking past it.

The car explodedwhileI was walking past it.
WhileI was walking past the car
it exploded.
Notice that the long action and short action are relative.
  • "Watching TV" took a few hours. "Telephoned" took a few seconds.
  • "Walking past the car" took a few seconds. "Exploded" took a few milliseconds.

Past Perfect Tense

had sung
The past perfect tense is quite an easy tense to understand and to use. This tense talks about the "past in the past".

How do we make the Past Perfect Tense?

The structure of the past perfect tense is:
subject+auxiliary verb HAVE+main verb

conjugated in simple past tense
past participle
hadV3
For negative sentences in the past perfect tense, we insert not between the auxiliary verb and main verb. For question sentences, we exchange the subject and auxiliary verb. Look at these example sentences with the past perfect tense:

subjectauxiliary verb
main verb
+Ihad
finishedmy work.
+Youhad
stoppedbefore me.
-Shehadnotgoneto school.
-Wehadnotleft.
?Hadyou
arrived?
?Hadthey
eatendinner?
When speaking with the past perfect tense, we often contract the subject and auxiliary verb:
I hadI'd
you hadyou'd
he had
she had
it had
he'd
she'd
it'd
we hadwe'd
they hadthey'd
  
WSM Image
The 'd contraction is also used for the auxiliary verb would. For example, we'd can mean: 
  • We had
    or
  • We would
But usually the main verb is in a different form, for example: 
  • We had arrived (past participle)
  • We would arrive (base)
It is always clear from the context.

How do we use the Past Perfect Tense?

The past perfect tense expresses action in the past before another action in the past. This is the past in the past. For example:
  • The train left at 9am. We arrived at 9.15am. When we arrived, the train had left.
The train had left when we arrived.
pastpresentfuture
Train leaves in past at 9am.

9
9.15



We arrive in past at 9.15am.

Look at some more examples:
  • I wasn't hungry. I had just eaten.
  • They were hungry. They had not eaten for five hours.
  • I didn't know who he was. I had never seen him before.
  • "Mary wasn't at home when I arrived."
    "Really? Where had she gone?"
You can sometimes think of the past perfect tense like the present perfect tense, but instead of the time being now the time is past.

For example, imagine that you arrive at the station at 9.15am. The stationmaster says to you:
  • "You are too late. The train has left."
Later, you tell your friends:
  • "We were too late. The train had left."
We often use the past perfect tense in reported speech after verbs like said, told, asked, thought, wondered:
Look at these examples:
  • He told us that the train had left.
  • I thought I had met her before, but I was wrong.
  • He explained that he had closed the window because of the rain.
  • I wondered if I had been there before.
  • I asked them why they had not finished.

How do we use the Past Perfect Continuous Tense?

The past perfect continuous tense is like the past perfect tense, but it expresses longer actions in the pastbefore another action in the past. For example:
  • Ram started waiting at 9am. I arrived at 11am. When I arrived, Ram had been waiting for two hours.
Ram had been waiting for two hours when I arrived.
pastpresentfuture
