Past Perfect Tense
The Past Perfect Tense is used to express an action completed before a certain moment in the past (usually, a long time ago). For example, "I met him in Australia in 2015. I had seen him last three years before". (The sense of time in this sentence refers to a completed action in past and especially a long time ago).
Rules: Helping verb "had" is used in sentence. 3rd form of verb is used in sentence.
Structure of Sentence
Positive Sentence
- Subject + helping verb (had) + (3rd form of verb) + object
Examples
- He had written a book.
- They had written a book.
Negative Sentence
- Subject + helping verb (had) + not + (3rd form of verb) + object
Note:
- In negative sentence, "not" is added between helping verb and main verb.
Examples
- He had not written a book.
- They had not written a book.
- What had you planned?
Interrogative Sentence
- Helping verb (Had) + subject + (3rd form of verb) + object
Note:
- Interrogative sentence starts with helping verb "Had".
- The words "what, where, when, how, etc." will be used before "had" in such kind of interrogative sentences.
Examples
- Had he written a book?
- Had they written a book?
Note: If two actions happened in the past, it may be necessary to show which action happened earlier than the other. The Past Perfect is mainly used in such situations. The Simple Past is used in one clause and the Past Perfect in the other; as,
- When I reached the station the train had started (so I couldn't get into the train).
- I had done my exercise when he came to see me.
- I had written the letter before he arrived.
Interrogative Negative Sentence
- Helping verb ("Had") + subject + not + (3rd form of verb) + object
Note:
- Helping verb "Had" is placed at the beginning of the sentence and "not" is used after the subject.
Examples
- Had he not written a book?
- Had they not driven a car?
Rule: Must put Question Mark (?) in the end of interrogative and interrogative negative sentences.
