Grammar - Past Perfect




Compiled from Grammar Builder, Book 3



The past perfect is:
Had   +   past participle

The rules of past perfect:
  1. Used to refer to an action or situation that happened earlier, and the past simple for an action or situation that took place later.
Eg         Past Simple       +       Past Perfect
    • When we arrived,               Peter had left. (= We did not meet Peter.)
    • When we reached the theatre, the concert had begun. (= We were late for the concert.)

    Past Perfect       +       Past Simple
·         Peter had left            when we arrived.
·         The concert had begun when we reached the theatre.

  1. Used with words like already, before and just to refer to actions that were completed before a specific time in the past.
    • By the time I got to the bus stop yesterday, the bus had already left.
    • The bus had left before I got to the bus stop yesterday.
    • The bus had just left when I got to the bus stop yesterday.

Important!
Verbs in the past perfect are formed in this way:
Regular verb
  • We had discussed with our friends about our travel plans before we booked our tickets.

Irregular verb
  • The thief had stolen the necklace before anyone noticed it was missing.

Verb ‘to be’
  • When I arrived at the restaurant yesterday, I knew I had been there before.

Verb ‘to have’
  • We had had our dinner when John invited us over to his house.
