In each sentence, the subject is not performing the action, but rather receiving or experiencing the action, which is why we use the passive form of the verb. The passive form is created by using the appropriate form of the verb 'to be' (such as 'is', 'are', 'was', 'were', etc.) followed by the past participle form of the main verb.
