Past Perfect (Past Tenses)

EXAMPLE:

• I had written the letter before you came home.
• If she had studied hard, she would have passed the English language exam.
• I wish I had been brave enough.
• Mary looked as if she had not slept for 45 hours.

We use the Past Perfect tense to emphasize that an action in the past finished before another action in the past started. This tense is also used in reported speech, third conditional sentences, or to show dissatisfaction with the past.

USE

1. A completed action before another action in the past
2. Third conditional sentences
3. Reported speech
4. Dissatisfaction with the past

USE 1: A completed action before another action in the past 
The first use of this tense is to emphasize that one action in the past happened before another action in the past.
Examples:
I had finished my homework before I went playing football.
John had never been to London before we went there last year.

Good to know
People (especially native speakers) do not use the Past Perfect in such sentences very often. For example, they will say:

• After I washed my car, I went to fill up.

Rather than:

• After I had washed my car, I went to fill up.

This is because "after" or "before" tell the listener which action happened first. Still, keep in mind that it is better to use the Past Perfect, especially in written English or when writing exams.
Explanation
In this cartoon, you can see a man who says: "My son, Julius, had never seen a camel, before we went together to the Zoo in summer 1990 ".

• Why is this in Past Perfect? Click on the button labled "event 1". The father asks his son, Julius, the following question: "Have you ever seen a camel?". Julis replies that he has never seen it. In the next scene, they are in the Zoo, watching the animal. Notice that the event 1 occured before event 2. It means that the use of Past Perfect is correct here.

USE 2: Third conditional sentences 
Use the Past Perfect with third conditional sentences.
Examples:

• If we had gone by taxi, we wouldn't have been late.
• If Mary had studied harder, she would have passed the exam.

The Use 2 is the so-called hypothetical past: we are talking about things that never happened.

• I wish I had fixed my umberella. (but I didn't)
• If only I had known the answer to that question. (but I didn't)

USE 3: Reported speech 
Use the Past Perfect with reposted speech.
Examples:

• Mary said she had already seen this film.
• He asked if I had read Harry Potter.

USE 4: Dissatisfaction with the past 
We often use the Past Perfect to show our dissatisfaction with the past. Such sentences typically start with "I wish ..." or "If only ...".
Examples:

• I wish I had taken more food. I'm hungry now.
• If only I had taken more food. I'm hungry now.

The Past Perfect is also used with expressions such as: "as if/though":

• John looked as if he had done something terrible.
• She looked as though she hadn't slept all night.
