Today, we will explore the active voice. In an active sentence, the subject performs the action of the verb. Can anyone give me an example of an active sentence?
The dog chased the ball.
Great example! In this case, 'the dog' is the subject performing the action of chasing. Remembering 'Subject + Verb + Object' will help you structure these sentences clearly. Now, what is the advantage of using the active voice?
It makes sentences clearer and more direct.
Exactly! Clarity is key in writing. Let’s summarize: active voice emphasizes the subject doing the action, leading to concise communication.

Now let’s shift our focus to the passive voice. In passive constructions, the subject receives the action instead of doing it. Does anyone remember the structure of a passive sentence?
It’s 'Object + form of to be + past participle.'
Correct! For instance, in the sentence 'The ball was chased by the dog,' we see that 'the ball' is now the focus. Can anyone think of a situation where using passive voice is preferred?
When the doer is unknown, like 'The documents were lost.'
Exactly! This helps us emphasize the action itself rather than who performed it. Remember, passive voice can help in formal writing or when we want to be vague about the doer.

Next, we will practice transforming sentences from active to passive voice. Who can transform this sentence for me: 'The teacher explains the topic.'
The topic is explained by the teacher.
Well done! The structure you followed shows us the transformation correctly. Would anyone like to try another one?
Yes! 'The cat caught the mouse' becomes 'The mouse was caught by the cat.'
Perfect! Make sure to pay attention to the tense as well. So, remember, when switching voices, maintain the verb tense and adjust the sentence structure accordingly.
Exercises: Identifying Active vs Passive

Let's identify whether these sentences are in active or passive voice. I’ll read a sentence, and you tell me which it is. Ready? 'The cake was eaten by the children.'
That’s passive voice!
Correct! Now, how about this one: 'Sarah completed her project.'
That’s active voice!
Excellent! It's important to distinguish between the two as it affects how we perceive the action within sentences.

Quick Overview
Standard
In this section, students learn about the active and passive voice in English. It explains how the active voice is used when the subject performs the action, while the passive voice focuses on the action received by the subject. Key structures for transforming sentences between these voices are provided, along with examples.
Detailed
Active and Passive Voice – Changing Sentence Focus
This section focuses on the distinction between active and passive voice in English grammar, which is vital for understanding sentence structure and enhancing clarity in writing. The active voice is identified as the structure where the subject performs the action, resulting in clear and direct sentences. For example, in the sentence "The boy ate the apple," the subject (the boy) is actively doing something.
Conversely, the passive voice occurs when the focus shifts to the action being received by the subject. It is structured using a form of the verb 'to be' followed by the past participle of the main verb. An example given is "The apple was eaten by the boy," where the emphasis is placed on the action (the apple being eaten) rather than who performed it.
Key points:
- Active Voice Usage: It's more straightforward and typically leads to clearer communication.
- Passive Voice Usage: Useful when the doer is unknown or unimportant or when the emphasis is on the action itself.
- Transformation Rules: Guidelines are provided for converting sentences between active and passive forms across different tenses (present, past, future).
- Practical Applications: The section includes practice exercises for students to identify and transform sentences between voices, thereby enhancing their competencies in sentence construction and comprehension.
The significance of this section lies in its ability to refine students' writing skills, making their expressions more versatile and impactful.

- Active Voice:
- In the active voice, the subject performs the action. It is usually more direct, clear, and concise.
- Structure: Subject + Verb + Object
- Example: The boy ate the apple. (The boy is doing the action)
- Example: The teacher praised the students. (The teacher is doing the action)
Detailed Explanation
In active voice sentences, the subject is the one who actually does the action. This makes the sentence straightforward because it's clear who is performing the action. The structure of an active voice sentence follows a specific order: first, you mention the subject, then the verb, and finally the object. For instance, in the sentence 'The boy ate the apple,' 'the boy' is the one doing the eating and 'the apple' is what is being eaten. By using active voice, sentences are typically easier to understand and more engaging to read, as they directly state the action.
Examples & Analogies
Think of active voice like a sports game where the players are actively participating. For example, if a basketball player shoots the ball and makes a basket, you say, 'The player made the shot.' This is clear and immediate. In contrast, if you say, 'The shot was made by the player,' it sounds like someone is simply reporting a highlight reel, which is less exciting.

- Passive Voice:
- In the passive voice, the subject receives the action. The focus is on the action itself or the object that receives the action, rather than who performed it. It is formed using a form of the verb 'to be' + the past participle of the main verb.
- Structure: Object of Active Sentence + form of 'to be' + Past Participle + (by + Agent/Subject of Active Sentence - optional)
- Example: The apple was eaten by the boy. (The apple received the action)
- Example: The students were praised by the teacher. (The students received the action)
Detailed Explanation
In passive voice sentences, the subject is no longer the doer of the action but rather the receiver of the action. This shifts the focus away from the doer and puts it on the receiver. The passive voice is created using a form of 'to be' combined with the past participle of the main verb. So in the sentence 'The apple was eaten by the boy,' the emphasis is on 'the apple' which was acted upon, rather than on the boy who did the action. This structure can be useful in situations where the doer is unknown or less important than the action itself.
Examples & Analogies
Consider a news report covering a storm that caused damage. If the headline reads, 'The house was damaged by the storm,' it emphasizes the impact of the storm rather than specifying who or what was responsible for the damage. This style is often used in formal writing and journalism to focus more on the event and its consequences than on the people involved.
When to Use Passive Voice

When to Use Passive Voice:
- When the doer of the action is unknown or unimportant.
- When you want to emphasize the action or the receiver of the action.
- In formal or scientific writing.
Detailed Explanation
Passive voice is beneficial in certain situations. For instance, if you don't know who performed the action or it doesn't matter, passive voice allows you to communicate effectively without that information. Additionally, if the action itself is more significant than who performed it, passive constructions can help highlight that action. Lastly, in formal writing, like scientific papers, passive voice is frequently used to maintain objectivity and focus on the results rather than on the researcher.
Examples & Analogies
Imagine a detective investigating a crime. If the detective says, 'The wallet was stolen,' they might not know who stole it, so they focus on the wallet itself. This helps keep the attention on the crime rather than the identity of the thief, which may not be known at that moment. This type of language is similar to how scientists present research findings; they often write in passive voice to focus on their results rather than their personal involvement.
Simple Transformations (Active to Passive)

Simple Transformations (Active to Passive):
- Present Simple: Subject + V1 + Object → Object + is/am/are + V3 + (by Subject)
- Active: He writes a letter.
- Passive: A letter is written by him.
- Past Simple: Subject + V2 + Object → Object + was/were + V3 + (by Subject)
- Active: She bought a car.
- Passive: A car was bought by her.
- Future Simple: Subject + will + V1 + Object → Object + will be + V3 + (by Subject)
- Active: They will build a house.
- Passive: A house will be built by them.
Detailed Explanation
Transforming sentences from active to passive involves changing how the information is presented. There are different formulas depending on the tense of the verb in the active voice. For the present simple, you start with the object of the active sentence, followed by a form of 'to be,' and then add the past participle of the verb. Similarly, the past and future simple tenses have their own transformations: for past simple, you would use 'was' or 'were,' and for future simple, 'will be.' Understanding these transformations allows you to showcase the same action from multiple perspectives.
Examples & Analogies
Think of it like a movie unfolding from different character viewpoints. In an action scene, you might see the hero stealing a treasure ('The hero steals the treasure'), but you could also present it from the treasure's point of view ('The treasure is stolen by the hero'). Both tell the same story but highlight different aspects: who is acting versus what is being acted upon.
