Simple past • Past continuous • Past perfect • Past perfect continuous


Simple Past

SIMPLE PAST

BE CAREFUL!
The simple past in English may look like a tense in your own language, but the meaning may be different.

1. Simple Past: Form

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

Irregular verbs:
 see list of verbs

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

·          I was in Japan last year
·          She had a headache yesterday.
·          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.

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

Examples: Simple past, irregular verbs

·          He went to a club last night.
·         Did he go to the cinema last night?
·          He didn't go to bed early last night.

·         Did Barry give you my passport?
to come
·          My parents came to visit me last July.
·         We didn't come because it was raining.
·         Did he come to your party last week?

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 placedafter the period of time e.g. a week ago, three years ago, a minute ago.

Examples

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

Verb Tenses: Past Continuous

PAST CONTINUOUS

Past continuous - form.

The past continuous of any verb is composed of two parts : the past tense of the verb to be (was/were), and the base of the main verb +ing.
Subject
was/were
base-ing
They
were
watching

Affirmative
She
was
reading
Negative
She
wasn't
reading
Interrogative
Was
she
reading?
Interrogative negative

she

Example: to play, past continuous

Affirmative
Negative
Interrogative

I was not playing
Was I playing?
You were playing
You were not playing
Were you playing?
He, she, it was playing
She wasn't playing
Was she playing?
We were playing
We weren't playing
Were we playing?
You were playing
You weren't playing
Were you playing?
They were playing
They weren't playing
Were they playing?

Past continuous, function

The past continuous describes actions or events in a time before now, which began in the past and was still going on at the time of speaking. In other words, it expresses anunfinished or incomplete action in the past.
It is used:
·         often, to describe the background in a story written in the past tense, e.g. "The sunwas shining and the birds were singing as the elephant came out of the jungle. The other animals were relaxing in the shade of the trees, but the elephant moved very quickly. She was looking for her baby, and she didn't notice the hunter who was watching her through his binoculars. When the shot rang out, she was running towards the river..."
·         to describe an unfinished action that was interrupted by another event or action: "Iwas having a beautiful dream when the alarm clock rang."
·          to express a change of mind: e.g. "I was going to spend the day at the beach but I've decided to go on an excursion instead."
·         with 'wonder', to make a very polite request: e.g. "I was wondering if you could baby-sit for me tonight."

More examples

·          They were waiting for the bus when the accident happened.
·          Caroline was skiing when she broke her leg.
·          When we arrived he was having a bath.
·          When the fire started I was watching television.
Note: with verbs not normally used in the continuous form, the simple past is used. See list in Present continuous

Verb Tenses: The Past Perfect

PAST PERFECT

The Past Perfect tense in English is composed of two parts: the past tense of the verb to have (had) + the past participle of the main verb.

Past perfect, function

The past perfect refers to a time earlier than before now. It is used to make it clear that one event happened before another in the past. It does not matter which event is mentioned first - the tense makes it clear which one happened first.
In these examples, Event A is the first or earliest event, Event B is the second or latest event:
Event B Event B
a.
John had gone out
when I arrived in the office.
Event A
Event B
b.
I had saved my document
before the computer crashed.
Event A
c.

we had already started cooking
Event B
Event A
d.
He was very tired
because he hadn't slept well.
Event B
Event A

Past perfect + just

'Just' is used with the past perfect to refer to an event that was only a short time earlier than before now, e.g.
·          The train had just left when I arrived at the station.
·          She had just left the room when the police arrived.
·          I had just put the washing out when it started to rain.

Verb Tenses: Past Perfect Continuous

The past perfect continuous is composed of two elements - the past perfect of the verb to be (=had been) + the present participle (base+ing).

trying
Negative

Past Perfect Continuous: Function

The past perfect continuous corresponds to the present perfect continuous, but with reference to a time earlier than 'before now'. Again, we are more interested in the process.

Examples

·         Had you been waiting long before the taxi arrived?
·         We had been trying to open the door for five minutes when Jane found her key.
·         It had been raining hard for several hours and the streets were very wet.
·          Her friends had been thinking of calling the police when she walked in.
This form is also used in reported speech. It is the equivalent of the past continuous and the present perfect continuous in direct speech:
·          Jane said "I have been gardening all afternoon."   Jane said she had been gardening all afternoon.
·          When the police questioned him, John said "I was working late in the office that night."   When the police questioned him, John told them he had been working late in the office that night.
