​

1. Have you had that headache for a long time? You should see a doctor about it.
To form the question, we use the auxiliary verb "have" in the present perfect tense, followed by the subject "you" and the main verb "had" in the past participle form. The word order in a question is inverted, so we start with the auxiliary verb.

2. Where have you been? Your clothes are really dirty!
To form the question, we use the auxiliary verb "have" in the present perfect tense, followed by the subject "you" and the main verb "been" in the past participle form. The word order in a question is inverted, so we start with the auxiliary verb.

3. Where did you stay when you were in London earlier this year?
To form the question, we use the auxiliary verb "do" in the past simple tense, followed by the subject "you" and the main verb "stay" in the base form. The word order in a question is inverted, so we start with the auxiliary verb.

4. We visited my cousins while we were in Rome last month.
This sentence is in the past simple tense, describing a completed action in the past. The subject "we" is followed by the main verb "visited" in the base form. The prepositional phrase "my cousins" indicates who they visited, and "while we were in Rome last month" provides additional information about the time.

5. I have finished the assignment, but I haven't given it in yet.
To form the negative, we add "not" between the auxiliary verb "have" and the main verb "given" in the past participle form. The word "yet" indicates that the action hasn't been completed at the time of speaking. The sentence is in the present perfect tense, indicating that the action of finishing the assignment is relevant to the present.
