Which tense is formed using "has" or "have" with the past participle?

The present perfect tense is formed by combining "has" or "have" with the past participle of a verb. This construction allows us to convey actions or events that have occurred at an unspecified time in the past and are relevant to the present, emphasizing the connection between past actions and their present implications.

For instance, in the sentence "She has completed her homework," the verb "has" and the past participle "completed" together illustrate that the action of completing the homework has been accomplished and is significant to the current moment.

In contrast, the other tenses listed do not use this specific structure. The future perfect tense utilizes "will have" with the past participle, while the past perfect tense is formed with "had" and the past participle. The present progressive tense is characterized by a form of "be" combined with the present participle, completely different from the perfect tense structure.
