### Active and Passive Voice: Explained with Examples
In grammar, **active** and **passive voice** are two different ways of expressing the relationship between the subject and the action in a sentence.
### **Active Voice:**
In the active voice, the **subject** of the sentence performs the action expressed by the verb. The focus is on the subject who is doing something.
#### Structure:
- **Subject + Verb + Object**
#### Example:
- **She (subject) kicked (verb) the ball (object).**
- In this sentence, **"She"** is the one who is performing the action (kicking), and **"the ball"** is the object receiving the action.
### **Passive Voice:**
In the passive voice, the **object** of the action becomes the **subject** of the sentence. The focus shifts to the action itself or the recipient of the action, rather than who is performing it.
#### Structure:
- **Subject + Form of "to be" (am, is, are, was, were, etc.) + Past Participle of the verb + (by + agent)**
- The agent (the person or thing doing the action) is often optional and may be omitted, especially if it is unknown or irrelevant.
#### Example:
- **The ball (subject) was kicked (verb) by her (agent).**
- In this passive construction, the focus is on **"the ball"** (the object from the active sentence), which is now the subject of the sentence. The action is still described, but the person performing the action (her) is not the main focus.
### Detailed Example:
Let’s look at a more detailed example to understand how sentences shift from active to passive.
1. **Active Voice:**
- **The teacher (subject) explained (verb) the lesson (object).**
- Here, **"The teacher"** is the subject doing the action, **"explained"** is the verb, and **"the lesson"** is the object receiving the action.
2. **Passive Voice:**
- **The lesson (subject) was explained (verb) by the teacher (agent).**
- In this passive construction, **"The lesson"** (the object of the active sentence) becomes the subject. The verb changes to a form of "to be" (in this case, "was") plus the past participle "explained". The agent, "the teacher," can be included (optional), especially if it's important to know who performed the action.
### When to Use Active and Passive Voice:
- **Active Voice** is preferred in most cases because it is clearer, more direct, and easier to understand. It's generally used when the doer (subject) is important.
- **Example**: "The chef cooked the meal."
- In this case, the focus is on the chef who performed the action.
- **Passive Voice** is often used when the **doer of the action is unknown, irrelevant, or unimportant**. It can also be used to emphasize the action itself or the recipient of the action rather than the one doing it.
- **Example**: "The meal was cooked."
- Here, the focus is on the meal, not on who cooked it. This might be used if the chef is unknown or not important to the context.
### Common Uses of Passive Voice:
- When the doer is **unknown**:
- **The window was broken.** (Who broke it is not specified.)
- When the doer is **unimportant**:
- **The report was completed.** (Who completed it doesn't matter.)
- To emphasize the **action** or **result**:
- **The cake was eaten.** (Focus is on the fact that the cake was eaten, not who ate it.)
### Summary:
- **Active voice** focuses on the subject (the doer of the action).
- **Passive voice** focuses on the object (the receiver of the action).
Both voices have their place in writing and speaking, and understanding when to use each can help make communication clearer and more effective.
