ACTIVE AND PASSIVE

141. Notice carefully the following sentences; select the subjects in these sentences which show who or what performed the action; select the subjects that show who or what receives the action. Do you notice any difference in the meaning of these sentences? Do you notice any difference in their form?

The engine struck the man.

The man was struck by the engine.

The system enslaves men.

Men are enslaved by the system.

Leaders often betray the people.

The people are often betrayed by leaders.

Let us look carefully at the first two sentences. You remember when we studied transitive verbs we found that every transitive verb had an object which was the receiver of the action expressed in the verb. Now you notice in this first sentence, The engine struck the man, we have the transitive verb struck. Engine is the subject of the verb and man is the object of the verb, the receiver of the action expressed by the verb struck.

Now in the sentence, The man was struck by the engine, we have the same thought expressed but in a different manner. The word man, which was the object of the verb struck in the first sentence, has now become the subject of the sentence, and we have changed our verb form from struck to was struck. In the first sentence of the subject, engine was the actor. In the second sentence, The man was struck by the engine, the subject of the sentence, man, is the receiver of the action expressed in the verb.

142. So we have thus changed the verb form from struck to was struck to indicate that the subject of the verb is the receiver of the action. Struck is called the active form of the verb because the subject of the verb is the actor. Was struck is called the passive form of the verb because the subject receives the action. Passive means receiving. In the passive form the subject is the receiver of the action expressed in the verb.

143. You remember that complete verbs have no object or complement, therefore it would follow that they cannot be put in the passive form for there is no object to become the receiver of the action. Take the complete verb, sleep, for example. We do not sleep anything, hence sleep has no passive form for there is no object which can be used as the subject, the receiver of the action.

Only transitive verbs can be put into the passive form. Remember that a transitive verb in the passive form is one that represents its subject as receiving the action.

The present, past, future and all the perfect time forms of transitive verbs can be changed from active to passive. The progressive time forms can be changed into the passive, but it makes an awkward construction and should be avoided as much as possible. Occasionally, however, we find it worth our while to use these forms, as for example:

The book is being written by the man.

This is the passive form of the present progressive, The man is writing a book.

The book was being written by the man.

This is the passive form of the past progressive, The man was writing the book.

144. The future progressive passive is awkward, and the present and past progressive forms are the only forms we find used in the passive. The best writers use them sparingly for we can usually say the same thing by using the active form of the verb and have a sentence which sounds much better.
