Past Perfect Tense
The past perfect tense is a verb form used to describe an action that occurred before another past action. It is formed using the auxiliary verb "had" and the past participle of the main verb. For example, "I had eaten breakfast before I left for school." In this sentence, the action of eating breakfast has already been completed before the action of leaving for school.
Formation
The past perfect tense is formed by combining the auxiliary verb "had" with the past participle of the main verb. The past participle is typically formed by adding "-ed" or "-en" to the base form of the verb. For example, "I had studied French before I moved to Paris."
Positive Sentences
Positive sentences in the past perfect tense typically describe an action that was completed before another past action. For example, "She had finished her homework before she watched TV." In this sentence, the action of finishing the homework is completed before the action of watching TV.
Negative Sentences
Negative sentences in the past perfect tense are formed by adding "not" after the auxiliary verb "had." For example, "I hadn't eaten breakfast before I left for school." In this sentence, the negation "not" is added after "had" to form the negative sentence.
Interrogative Sentences
Interrogative sentences in the past perfect tense are formed by rewriting the sentence in the interrogative (question) form. For example, "Did you study French before you moved to Paris?"
