UNIT #2 PAST PERFECT

IN  THIS UNIT, WE LET'S STUDY USE OF PAST PERCEST


Past Perfect
Form

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


Examples

Affirmative sentences:
I had played hockey.
I'd played hockey.
You had played hockey.
You'd played hockey.
Negative sentences:
I had not played hockey.
I'd not played hockey.
I hadn't played hockey.
You had not played hockey.
You'd not played hockey.
You hadn't played hockey.

 Use

1) Together with the Simple Past
When two past actions are combined - the first action, which was completed before the second one began, is put into Past Perfect.

EXAMPLES:
Mary had read the book before she watched a film.
After Amy had gone home it started to rain.

2) The past equivalent of the Present Perfect
He had played hockey.
Besonderheiten

The bike is new. I've bought it.
The bike was new. I had bought it.

Past Perfect - Simple Past
Simple Past - Simple Past
The match had started before he arrived.
The match started when he arrived.
