Passive voice, on the other hand, indicates that the subject of the sentence is being acted upon. Tense indicates when the action occurs. Present tense expresses action which is happening at the present time, or which happens continuously. Past tense indicates that the action was completed at some time in the past. Future tense expresses action, which will take place in the future.
Verbs are either transitive or intransitive.
A transitive verb communicates action and is always followed by an object, which receives the action. An object must receive the action of a transitive verb in order to complete the meaning of the verb. The object of a transitive verb is called the direct object if it receives the action directly from the subject. The bird ate the seed. Jim broke the dish.
