Past tenses
1.
Past simple
We use the past simple
a) to talk about single past actions or a clear sequence
of past actions.
Remember:
We don´t have to repeat the
subject if it doesn´t change.
She opened the envelope, (she) took out the letter and smiled.
b) to talk about past states.
I taught in that school for thirteen years.
2.
Past continuous
We use the past continuous
a) to describe past actions which were in progress at a
given time or period in the past.
b) at the beginning of a narrative we use the past
continuous to set the scene:
The lawyers were looking through their papers preparing their arguments
for the trial to come. The defendant´s wife was anxiously twisting a
handkerchief between her fingers.
c) to show an action was in progress when another action
took place:
We were watching TV when we heard a loud bang from the street below.
d) to show that different actions were in progress at the
same time:
While we were lying on the beach someone was going through our things in
the hotel room.
Remember:
We can often leave out
was/were and use the present participle on its own. As in the past simple, we
don´t have to repeat the subject if it doesn´t change:
Shoppers were crowding round the counter, (they were) snatching bargains
from under each other´s noses.
3.
Past perfect
We use the past perfect
a) to show that an action happened earlier than a later
action:
By the time we got there, the film had already started.
Remember:
The past perfect is also
used in the condition clause of the third conditional, and to express past
regrets with wish.
4.
Past perfect continuous:
We use the past perfect
continuous:
a) to show that an action had started and was still in
progress when another action took place:
We had been studying there for ages when the night bus finally turned
up.
b) to describe repeated actions up to a point in the
past:
I had been ringing her all morning but I couldn´t get a reply.
