Understanding Active and Passive Voice Conversion

When we convert a sentence from active voice to passive voice, we change the focus of the sentence from the doer of the action (subject) to the action itself or the receiver of the action (object). The structure of the verb also changes depending on the tense of the original sentence.

Let's analyse the given sentence: You have made a mistake in writing your answer.

Analyzing the Active Sentence

• Subject: You (the doer of the action)
• Verb: have made (the action)
• Object: a mistake (the receiver of the action)
• Tense: Present Perfect Tense (structure: Subject + has/have + Past Participle (V3))
• Remaining part: in writing your answer

Converting Present Perfect Active to Passive Voice

The general structure for converting a sentence in Present Perfect Tense from active to passive voice is:

Active: Subject + has/have + V3 + Object

Passive: Object + has/have + been + V3 + by + Subject

The choice between 'has' and 'have' in the passive voice depends on the new subject (which was the object in the active sentence). If the new subject is singular or 'he', 'she', 'it', use 'has'. If the new subject is plural or 'I', 'we', 'you', 'they', use 'have'.

Applying the Conversion Rule

Let's apply this rule to the sentence "You have made a mistake in writing your answer."

1. Identify the object of the active sentence: "a mistake". This becomes the subject of the passive sentence.
2. Determine the correct auxiliary verb for the new subject. The new subject is "a mistake", which is singular. So, we use "has".
3. Add "been" after the auxiliary verb.
4. Use the past participle (V3) of the main verb "made". The past participle of "make" is "made".
5. Add "by" followed by the original subject "you".
6. Add the remaining part of the sentence: "in writing your answer".

Putting it all together, the passive sentence is: A mistake has been made by you in writing your answer.

Evaluating the Options

Let's look at the given options and see which one matches our converted sentence:

Based on the conversion rules and analysis, option 2 is the correct passive form of the given sentence.

Additional Information on Voice Change

Changing the voice of a sentence is a fundamental concept in English grammar. It allows us to shift the emphasis of the sentence.

• Active Voice: Emphasizes the subject performing the action. It is generally more direct and concise.
• Passive Voice: Emphasizes the action or the object receiving the action. It is often used when the doer of the action is unknown, unimportant, or obvious from the context.

Remember that only transitive verbs (verbs that take an object) can be changed into the passive voice.

Understanding the structure for converting different tenses is key to correctly changing the voice of a sentence. Pay close attention to the auxiliary verbs and the form of the main verb (always the past participle in passive voice).
