USE 1 Completed Action Before Something in the Past
The Past Perfect expresses the idea that something occurred before another action in the past. It can also show that something happened before a specific time in the past.
Examples:
- I had never seen such a beautiful beach before I went to Kauai.
- I did not have any money because I had lost my wallet.
- Tony knew Istanbul so well because he had visited the city several times.
- Had Susan ever studied Thai before she moved to Thailand?
- She only understood the movie because she had read the book.
- Kristine had never been to an opera before last night.
- We were not able to get a hotel room because we had not booked in advance.
USE 2 Duration Before Something in the Past (Non-Continuous Verbs)
With Non-Continuous Verbs we use the Past Perfect to show that something started in the past and continued up until another action in the past.
Examples:
- We had had that car for ten years before it broke down.
- By the time Alex finished his studies, he had been in London for over eight years.
- They felt bad about selling the house because they had owned it for more than forty years.
Although the above use of Past Perfect is normally limited to Non-Continuous Verbs and non-continuous uses of Mixed Verbs, the words "live," "work," "teach," and "study" are sometimes used in this way even though they are NOT Non-Continuous Verbs.
