Understanding Active and Passive Voice Transformation

The question asks us to convert a sentence from active voice to its passive form. The given sentence is: "The government will build an amphitheatre."

In this sentence:

• Subject: The government
• Verb: will build
• Object: an amphitheatre

The sentence is in the Future Simple tense and is in the active voice because the subject ("The government") is performing the action ("will build").

Converting Future Simple Active to Passive Voice

To change a sentence from Future Simple active voice to passive voice, we follow a specific structure. The general formula for Future Simple passive voice is:

\(\text{Object} + \text{will be} + \text{Past Participle of Verb} + (\text{by} + \text{Subject})\)

Let's apply this formula to the given sentence:

1. Identify the object of the active sentence: "an amphitheatre". This becomes the new subject in the passive sentence.
2. Use the auxiliary verbs "will be".
3. Find the past participle of the main verb "build". The forms are build (base) > built (past simple) > built (past participle). So, the past participle is "built".
4. Include the original subject introduced by "by": "by the government".

Putting it all together, the passive form is: "An amphitheatre will be built by the government."

Analyzing the Given Options for Passive Voice

Let's examine each option provided:

• Option 1: An amphitheatre will be build by the government.
  This option uses the base form of the verb "build" instead of the past participle "built". This is incorrect for passive voice construction.
• Option 2: An amphitheatre will be built by the government.
  This option correctly uses the structure: Object ("An amphitheatre") + will be + Past Participle ("built") + by + Subject ("the government"). This matches the rule for Future Simple passive voice.
• Option 3: An amphitheatre would be built by the government.
  This option uses "would be" instead of "will be". While "would" can be used in certain contexts (like conditional sentences or reported speech), "will be" is the standard auxiliary for transforming Future Simple active to passive voice when the original sentence uses "will". This is incorrect for a direct transformation of "will build".
• Option 4: An amphitheatre be build by the government.
  This option is grammatically incorrect. It omits the auxiliary verb "will" and uses the base form "build" instead of the past participle "built".

Based on the analysis, Option 2 correctly follows the rules for converting the sentence to the passive voice in the Future Simple tense.

Additional Information on Active and Passive Voice

Understanding active and passive voice is key to mastering English sentence structure. Here's a little more detail:

• Active Voice: In active voice, the subject performs the action. It is generally more direct, clear, and concise. Example: "She wrote the letter." (Subject 'She' performs the action 'wrote').
• Passive Voice: In passive voice, the subject receives the action. The focus is on the action and the object rather than the performer of the action. The performer can be included in a "by" phrase but is often omitted if unimportant or unknown. Example: "The letter was written by her." (The subject 'The letter' receives the action 'was written').
• When to Use Passive Voice:
  • When the doer of the action is unknown or unimportant.
  • When you want to emphasize the action or the recipient of the action.
  • In scientific or technical writing, where the process or result is more important than the person who performed the action.

Converting between active and passive voice helps in varying sentence structure and focusing on different parts of the information.
