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 verb	work explode like	worked exploded liked	worked exploded liked	The past form for all regular verbs ends in -ed.
irregular verb	go 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:

	subject	auxiliary verb		main verb
+	I			went	to school.
	You			worked	very hard.
-	She	did	not	go	with me.
	We	did	not	work	yesterday.
?	Did	you		go	to London?
	Did	they		work	at 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:

	subject	main verb
+	I, he/she/it	was		here.
	You, we, they	were		in London.
-	I, he/she/it	was	not	there.
	You, we, they	were	not	happy.
?	Was	I, he/she/it		right?
	Were	you, we, they		late?

Use of the Simple Past Tense >>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 be short 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?
past	present	future
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?
past	present	future
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

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:

·         I 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?

·         I 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 was cold. The door opened and James Bond entered. He took off his coat, which was very wet, and ordered a drink at the bar. He sat down in the corner of the lounge and quietly drank his..."

 

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:

	subject	auxiliary verb		main verb
+	I	was		watching	TV.
+	You	were		working	hard.
-	He, she, it	was	not	helping	Mary.
-	We	were	not	joking.
?	Were	you		being	silly?
?	Were	they		playing	football?

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.
past	present	future
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:

·         I 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 blowing hard. 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

past	present	future
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 car	when	it exploded.
When	the car exploded		I was walking past it.
	The car exploded	while	I was walking past it.
While	I 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.

 

Use the past continuous tense or simple past tense as appropriate.

 

 

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
		had		V3

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:

	subject	auxiliary verb		main verb
+	I	had		finished	my work.
+	You	had		stopped	before me.
-	She	had	not	gone	to school.
-	We	had	not	left.
?	Had	you		arrived?
?	Had	they		eaten	dinner?

When speaking with the past perfect tense, we often contract the subject and auxiliary verb:

I had	I'd
you had	you'd
he had she had it had	he'd she'd it'd
we had	we'd
they had	they'd

 

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.
past	present	future
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.

past perfect tense				present perfect tense
had | done | > |					have | done | > |
past	now	future		past	now	future

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.
