Present Perfect Tense Active Voice To Passive Voice 

Understanding the Present Perfect Tense:

Before diving into the conversion process, it is important to review the present perfect tense. This tense is used to describe actions that happened in the past but have a connection to the present. It is typically formed by using the auxiliary verb "have" (in its appropriate form) followed by the past participle of the main verb.

Conversion Process: Active Voice to Passive Voice

When transforming sentences from active voice to passive voice, certain changes need to be made. The subject of the active sentence becomes the object in the passive sentence, while the object in the active sentence becomes the subject in the passive sentence. Additionally, the verb tense changes from present perfect active to present perfect passive. Finally, the auxiliary verb "have" is used in the passive voice, followed by the past participle of the main verb.

Example 1:

Active Voice: She has written a book.

Passive Voice: A book has been written by her.

In the above example, the subject "She" becomes the object "a book" in the passive voice, while the verb "has written" changes to "has been written." The subject "She" is placed at the end of the sentence preceded by the preposition "by."
