Answer:

Step-by-step explanation:
What is passive voice?
When a sentence's subject gets the action rather than performing it, it is said to be in the passive voice. In other words, rather than on who or what is doing it, the attention is on what is happening to the subject.
Example
In this sentence, the object of the active sentence (him) becomes the subject of the passive sentence and the subject (mosquito) is now the object of the preposition "by." The verb "bitten" remains in the past participle form
The past participle of the main verb is used after a form of the auxiliary verb "to be" (such as "is," "am," "are," "was," "were," "has been," or "will be") to create the passive voice.
