4.3. Transformation Rules

Voice indicates whether the subject performs the action (active) or receives the action (passive).

● Active Voice: The subject performs the action (e.g., The boy kicked the ball.). It is generally preferred for clarity and directness.

● Passive Voice: The subject receives the action (e.g., The ball was kicked by the boy.). It is used when the doer of the action is unknown, unimportant, or when emphasizing the action or the receiver of the action.

In English, sentences can be structured in two voices: active and passive. The active voice focuses on the subject that does the action, while the passive voice emphasizes the action itself or the recipient of the action. For example, in 'The boy kicked the ball,' 'the boy' is the subject performing the action of kicking. In contrast, 'The ball was kicked by the boy' puts the focus on what happened to the ball, which is receiving the action.

Imagine a soccer game. When a player scores a goal, you can say, 'John scored the goal,' which is active voice. But if you say, 'The goal was scored by John,' that shifts the attention to the goal itself. This can be useful in reporting where the scorer might not be important, such as saying 'A goal was scored' when you just want to convey the event.

● Transformation Rules: Learn how to change sentences from active to passive voice and vice-versa for different tenses, by making the object of the active sentence the subject of the passive sentence and using the correct form of 'to be' + past participle of the main verb.

To transform sentences from active to passive voice, the object in the active sentence becomes the subject in the passive sentence. Additionally, the verb form changes. You must use 'to be' in the correct tense along with the past participle of the main verb. For instance, in the active sentence 'The chef cooks the meal,' 'the meal' becomes the subject in the passive sentence 'The meal is cooked by the chef.' The verb 'cooks' changes to 'is cooked,' showing the transformation from active to passive.

Think of a classroom scenario. If a teacher says, 'The students completed the project,' to express it in the passive voice, you would say, 'The project was completed by the students.' Here, we are shifting our focus from who completed the project (the students) to the project itself. This shift helps when we want to highlight the work done rather than the ones who did it.
