1. When we change an active construction into a passive construction, the direct object becomes the subject, the subject becomes an object.  
2. The action of the verb is directed toward the direct object: the verb passes its action onto the object; the object receives the action of the verb.  
3. Intransitive verbs do not have objects.  
4. Intransitive verbs are generally used only in the active voice. For example, the active constructions "she arrived yesterday; it happened to me; they disappeared" (with intransitive verbs "arrive, happen, disappear") cannot be changed into passive constructions.
