Present Perfect Tense

The Present Perfect Tense is used to describe actions or events that have been completed at some point in the past but are still relevant to the present. It is formed using the auxiliary verb "have" or "has" followed by the past participle of the main verb.

Structure:

• Positive: Subject + have/has + past participle (e.g., I have finished the work.)
• Negative: Subject + have/has + not + past participle (e.g., She has not seen the movie.)
• Interrogative: Have/Has + subject + past participle? (e.g., Have you eaten?)

Uses:

• To express experiences: I have visited Paris.
• To talk about recent actions with relevance to now: He has just left the room.
• To describe actions that started in the past and continue to the present: We have lived here for five years.
