Healthy habits and experience

The Present Perfect is have/has + the third form of the verb (past participle). With regular verbs it ends in -ed: visit – visited. Irregular ones are different: see – seen, go – been/gone, break – broken, write – written, do – done, eat – eaten. We ask about experience: “Have you ever ridden a camel?” — “Yes, I have.” / “No, I haven’t.” If we give a definite time (When? yesterday?), we use the Past Simple: “Yes, I have. I rode one in Nurata last year.” Just means a moment ago, already means earlier than expected (in the middle), and yet is used in questions and negatives (at the end): “I haven’t done my homework yet.” With he, she, it we use has: “She has seen a snake.”
