Present Perfect Tense:

The Present Perfect Tense is used to express actions or events that happened at an unspecified time before the present. In its interrogative form, it typically begins with “have” or “has.” To convert these questions into negative sentences, follow these steps:

• Change “have” or “has” to “haven’t” or “hasn’t” (the contracted forms of “have not” and “has not”).
• Add “not” after the auxiliary verb.
• Keep the main verb in its past participle form.

Example:

• Interrogative: Have you seen this movie?
• Negative: You haven’t seen this movie.

Now, let’s look at some more examples:

1. • Interrogative: Has she visited New York before?
   • Negative: She hasn’t visited New York before.

   • The Past Perfect Tense is used to indicate an action that occurred before another action in the past. In interrogative sentences, it usually begins with “had.” To change these questions into negative sentences, do the following:

     • Replace “had” with “hadn’t” (the contracted form of “had not”).
     • Add “not” after the auxiliary verb.
     • Maintain the main verb in its past participle form.

     Example:

     • Interrogative: Had they finished their homework?

     • The Future Perfect Tense is used to express an action that will be completed before a specific time in the future. In interrogative sentences, it often starts with “will have.” To convert these questions into negative sentences, apply the following transformations:

       • Replace “will have” with “won’t have” (the contracted form of “will not have”).
       • Add “not” after the auxiliary verb.
       • Retain the main verb in its past participle form.

       Example:

       • Interrogative: Will you have finished the project by next week?

To sum up, converting Perfect Tense interrogative sentences into negative sentences involves changing the auxiliary verbs (“have,” “has,” “had,” “will have”) to their negative forms (“haven’t,” “hasn’t,” “hadn’t,” “won’t have”) and adding “not” after the auxiliary verb. The main verb should remain in its past participle form.
