Present Perfect Negative Forms Exercises

Forming negative present perfect sentences is straightforward once you know the pattern: haven't (have not) or hasn't (has not) followed by the past participle. Use "haven't" with I, you, we, and they; use "hasn't" with he, she, and it. For example: "I haven't finished yet," "She hasn't called back." The word yet is very common in negative present perfect sentences — it means "up to now" and usually goes at the end of the sentence: "They haven't arrived yet." Another important negative word is never, which goes between the helper verb and the participle: "I have never been to Japan."

A key point for learners: never is already negative, so you do not add "not" — saying "I haven't never" is a double negative and is incorrect. Choose either "haven't + participle" or "have never + participle," but not both. In Cambridge exams, negative present perfect forms appear frequently in gap-fill and error correction tasks. Common mistakes include forgetting the helper verb ("I not finished" instead of "I haven't finished"), using the wrong helper verb ("He haven't" instead of "He hasn't"), and using the past simple instead of the past participle ("She hasn't went" instead of "She hasn't gone").
