Active and passive voice

Subject: English Language

Class: Basic 4

Topic: Active and Passive Voice

In the study of English Language, understanding how sentences are built is very important. Every sentence tells a story about an action. However, we can tell that story in two different ways depending on what we want to focus on. These two ways are called the Active Voice and the Passive Voice.

Core Concepts

1. What is the Active Voice?

The Active Voice is the most common way we speak and write. In an active sentence, the subject (the person or thing doing the action) comes first. The subject is the "star" of the sentence because they are the one performing the work.

For example, in the sentence "Amina swept the classroom," Amina is the subject because she is the one doing the sweeping. The word "swept" is the action (verb), and "the classroom" is the object (the thing being swept). Because the doer of the action comes first, we say the sentence is in the Active Voice. Active sentences are usually strong, clear, and direct.

2. What is the Passive Voice?

The Passive Voice is a bit different. In a passive sentence, the object (the person or thing receiving the action) moves to the beginning of the sentence. The person doing the action (the subject) is moved to the end, or sometimes they are left out completely.

Using our previous example, if we change it to Passive Voice, it becomes: "The classroom was swept by Amina." Notice how the classroom is now at the start of the sentence. The focus has shifted from Amina to the classroom itself. We use the Passive Voice when we want to emphasize what happened to something, rather than who did it.

3. How to Change Active to Passive

To change a sentence from active to passive, we follow a few important steps:

• Move the Object: Take the thing that received the action and put it at the start.
• Change the Verb: We add a "helping verb" (like is, are, was, or were) and change the main action word into its past participle form (for example, "eat" becomes "eaten," "break" becomes "broken").
• Add "By": We usually add the word "by" before the person who did the action.

Key Points to Remember

• The Doer vs. The Receiver: In the Active Voice, the doer (subject) is at the front. In the Passive Voice, the receiver (object) is at the front.
• The Word "By": The word "by" is a big clue! If you see a sentence that says something was done "by" someone, it is almost always in the Passive Voice.
• Verb Changes: Passive sentences always use a form of the verb "to be" (is, was, were, etc.) followed by the past participle of the main verb.
• Tense Consistency: If the active sentence is in the past tense (e.g., "kicked"), the passive sentence must also be in the past tense (e.g., "was kicked").

Contextual Examples

To understand this better, let us look at several examples that show how the sentence structure changes.

Example 1: In the Garden

• Active: Chidi planted the flowers. (Focus: Chidi)
• Passive: The flowers were planted by Chidi. (Focus: The flowers)

Example 2: During Lunch

• Active: The cat drank the milk. (Focus: The cat)
• Passive: The milk was drunk by the cat. (Focus: The milk)

Example 3: At School

• Active: Mr. Okafor taught the pupils. (Focus: Mr. Okafor)
• Passive: The pupils were taught by Mr. Okafor. (Focus: The pupils)

Example 4: Homework

• Active: Bola wrote a beautiful story. (Focus: Bola)
• Passive: A beautiful story was written by Bola. (Focus: The story)

Example 5: Household Chores

• Active: My mother cooked the rice. (Focus: My mother)
• Passive: The rice was cooked by my mother. (Focus: The rice)

Summary

The Active Voice is used when the subject of the sentence performs the action (e.g., The boy kicked the ball). It is direct and clear.

The Passive Voice is used when the subject receives the action (e.g., The ball was kicked by the boy). We use the passive voice to highlight the result of the action or the object involved.

To tell them apart, look at who is at the beginning of the sentence. If the "doer" is at the start, it is Active. If the "receiver" is at the start and you see the word "by," it is Passive. Understanding both voices helps us become better writers because we can choose which part of our sentence is the most important.
