Converting Passive Voice to Active Voice: "Has the custard not been cooked by her?"

Understanding how to convert sentences between passive and active voice is a fundamental skill in English grammar. The given sentence is in the passive voice and is an interrogative (question) sentence in the present perfect tense.

The sentence is: "Has the custard not been cooked by her?"

Let's analyze the structure of this passive voice sentence:

• Subject in passive voice: "the custard" (this was the object in the active voice)
• Auxiliary verb: "Has" (used because "the custard" is singular)
• Negation: "not"
• Past participle of the main verb: "cooked"
• Indicator of passive voice: "been" + past participle
• Subject of the action (agent): "her" (this was the subject in the active voice, introduced by "by")

The basic structure for a passive interrogative sentence in the present perfect tense with negation is: Has/Have + Object + not + been + Verb(V3) + by + Subject?

To convert this to the active voice, we need to reverse the structure. The agent ("her") becomes the subject ("she"), and the subject in the passive voice ("the custard") becomes the object.

The basic structure for an active interrogative sentence in the present perfect tense with negation is: Has/Have + Subject + not + Verb(V3) + Object?

Applying this to the given sentence:

• The new subject is "she".
• Since the subject is "she", the auxiliary verb is "Has".
• The negation "not" remains.
• The main verb is "cooked".
• The object is "the custard".

Putting it together, the active voice sentence is: Has she not cooked the custard?

Analyzing the Options for Active Voice Conversion

Let's examine the given options to find the correct active voice conversion of "Has the custard not been cooked by her?":

Option 1: Have she cooked the custard?

This option is incorrect because the auxiliary verb "Have" is used with the subject "she". The correct auxiliary verb for "she" in the present perfect tense is "Has". Also, this sentence is affirmative, not negative like the original.

Option 2: Has she cooked the custard?

This option uses the correct auxiliary verb ("Has") with the correct subject ("she") and the correct main verb ("cooked"). However, the original passive sentence included the negation "not". This active sentence is affirmative (positive) and does not retain the negation from the original sentence.

Option 3: Does she not cook the custard?

This option uses the correct subject ("she") and includes the negation ("not"). However, the tense is incorrect. "Does... cook" is in the simple present tense, whereas the original sentence is in the present perfect tense ("Has... been cooked").

Option 4: Has she not cooked the custard?

This option correctly identifies the new subject ("she") and uses the appropriate auxiliary verb for the present perfect tense ("Has"). It includes the negation ("not") from the original sentence and uses the correct main verb ("cooked") followed by the object ("the custard"). This sentence accurately reflects the meaning and tense of the original passive sentence in the active voice.

Therefore, the option that correctly expresses "Has the custard not been cooked by her?" in the active voice is "Has she not cooked the custard?".

Additional Information on Active and Passive Voice Conversion

Active voice sentences are generally more direct, clear, and concise. The subject performs the action.

Passive voice sentences emphasize the action itself or the object receiving the action, rather than the performer of the action. The subject receives the action.

Key steps in converting passive to active voice:

• Identify the subject of the passive sentence (which was the object in active).
• Identify the agent performing the action (usually after "by"). This will be the new subject in the active sentence.
• Identify the verb and its tense in the passive sentence.
• Convert the verb to the appropriate active form, ensuring the tense remains the same. The auxiliary verb "be" (am, is, are, was, were, been, being) and the past participle are typically replaced by the main verb in the correct tense.
• The subject of the passive sentence becomes the object in the active sentence.
• Ensure any negation or question structure is maintained.

In the case of the present perfect tense, the passive voice uses "Has/Have + been + V3". The active voice uses "Has/Have + V3". When converting from passive to active, the "been" is removed, and the subject and object are swapped, adjusting the auxiliary verb (Has/Have) if necessary based on the new subject.
