A verb form can be in the active voice or in the passive voice. Active verb forms are different from passive forms; however, sometimes they are confused. These mistakes are not very surprising because of the following reasons.
Be (is, am, are, was and were) can be used to make both passive forms and continuous forms in the active voice.
Past participles are used to make both passive verb forms and perfect tenses in the active voice.
