Active and Passive Verb Forms

Sentences can be active or passive. Therefore, tenses also have "active forms" and "passive forms." You must learn to recognize the difference to successfully speak English.

Active Form

In active sentences, the thing doing the action is the subject of the sentence and the thing receiving the action is the object. Most sentences are active.

[Thing doing action] + [verb] + [thing receiving action]

Examples:

The Facilitator             teaches                        the Students.

Subject doing action                              Verb                                               Object receiving action

Janny                           washes                         the glasses.

Subject doing action                              Verb                                                Object receiving action

Passive Form

In passive sentences, the thing receiving the action is the subject of the sentence and the thing doing the action is optionally included near the end of the sentence. You can use the passive form if you think that the thing receiving the action is more important or should be emphasized. You can also use the passive form if you do not know who is doing the action or if you do not want to mention who is doing the action.

[Thing receiving action] + [be] + [past participle of verb] + [by] + [thing doing action]

Examples:

The students                are taught        by the facilitator.

Subject receiving action                 passive verb                         doing action

The dishes                   are washed      by Janny.

Subject receiving action            passive verb                           doing action
