Form:

Affirmative: Subject + have/has + past participle
“I have visited Paris.” / “She has finished her homework.”

Negative: Subject + haven’t/hasn’t + past participle
“They haven’t arrived yet.” / “He hasn’t eaten anything.”

Interrogative: Have/Has + subject + past participle?
“Have you ever been to London?” / “Has she called you?”

Uses:

• Experience (no specific time): “I have been to Mecca twice.” / “Have you ever eaten couscous?”
• Change over time: “The population has increased significantly.” / “Technology has changed our lives.”
• Recent actions with present result: “I have lost my keys.” (I can’t find them now) / “She has broken her leg.” (it’s still broken)
• Unfinished actions (with for/since): “I have lived here for ten years.” / “She has worked at this school since 2015.”
