Don't touch the live wire.
Answer:
Let the live wire not be touched.
**Rule**: Negative imperative sentences (warnings/commands) are often converted to passive voice using the structure: **Let + object + not + be + V3**.
- **Correct Answer (a)**: This option correctly applies the 'Let' structure for a negative command. 'the live wire' is the object, followed by 'not be' and the past participle 'touched'.
- **Incorrect Answer (b)**: 'advised not to be touching' is an awkward and incorrect construction.
- **Incorrect Answer (c)**: This implies a rule or regulation, which is slightly different from a direct, urgent warning.
- **Incorrect Answer (d)**: 'Shouldn't' offers advice, which is weaker than the strong warning in the original sentence.
66382
They were not taking care of the garden.
Answer:
The garden was not being taken care of.
**Rule**: For a negative Past Continuous sentence with a phrasal verb, the passive structure is **Object + was/were + not + being + V3 + prepositions**. The agent 'by them' can be omitted.
- **Correct Answer (a)**: The object 'the garden' becomes the subject. The verb form 'was not being taken care of' correctly reflects the negative Past Continuous tense and retains the phrasal verb's particles. The agent is correctly omitted.
- **Incorrect Answer (b)**: This incorrectly changes the tense to Present Perfect.
- **Incorrect Answer (c)**: This incorrectly changes the tense to Simple Past.
- **Incorrect Answer (d)**: This incorrectly changes the tense to Present Continuous.
66383
Nobody was answering the phone.
Answer:
The phone was not being answered.
**Rule**: A negative sentence in the Past Continuous Tense (using 'Nobody') is converted to passive using **Object + was/were + not + being + V3**. The negative idea from 'Nobody' is transferred to the verb.
- **Correct Answer (a)**: The object 'the phone' becomes the subject. The passive verb 'was not being answered' correctly reflects the negative meaning and the Past Continuous tense. The agent is correctly omitted.
- **Incorrect Answer (b)**: This uses a double negative ('not' and 'nobody'), which is grammatically incorrect.
- **Incorrect Answer (c)**: This incorrectly changes the tense to Present Perfect.
- **Incorrect Answer (d)**: This incorrectly changes the tense to Present Continuous.
66384
I had to finish the work before the deadline.
Answer:
The work had to be finished by me before the deadline.
**Rule**: When the active sentence uses 'had to' to show past necessity, the passive form is **Object + had to + be + V3**.
- **Correct Answer (d)**: The object 'the work' becomes the subject. The structure 'had to be finished' is the correct passive form for the past necessity.
- **Incorrect Answer (a)**: 'was to be' implies a past plan, which is a different meaning.
- **Incorrect Answer (b)**: 'has to be' incorrectly changes the tense to the present.
- **Incorrect Answer (c)**: 'had been finished' is the passive of the Past Perfect Tense.
66385
His music has charmed everyone.
Answer:
Everyone has been charmed by his music.
**Rule**: For a sentence in the Present Perfect Tense, the passive voice structure is **Object + has/have + been + V3 + by + Subject**.
- **Correct Answer (d)**: The object 'everyone' becomes the subject. 'Everyone' is a singular pronoun, so 'has' is used, followed by 'been' and the past participle 'charmed'.
- **Incorrect Answer (a)**: This incorrectly changes the tense to Simple Past.
- **Incorrect Answer (b)**: This incorrectly changes the tense to Simple Present.
- **Incorrect Answer (c)**: This incorrectly changes the tense to Past Perfect.
66386
Who composed this piece of poetry?
Answer:
By whom was this piece of poetry composed?
**Rule**: Interrogative sentences in the Simple Past Tense starting with 'Who' are converted to passive voice using **By whom + was/were + object + V3?**
- **Correct Answer (b)**: 'Who' becomes 'By whom'. The object 'this piece of poetry' is singular, so 'was' is used, followed by the past participle 'composed'.
- **Incorrect Answer (a)**: This incorrectly changes the tense to Present Perfect.
- **Incorrect Answer (c)**: This incorrectly changes the tense to Simple Present.
- **Incorrect Answer (d)**: 'who' is the incorrect case; 'whom' is required after the preposition 'By'.
66387
You might have misunderstood the instructions.
Answer:
The instructions might have been misunderstood by you.
**Rule**: For sentences with past modals (modal + have + V3), the passive structure is **Object + modal + have been + V3 + by + Subject**.
- **Correct Answer (a)**: The object 'the instructions' becomes the subject. The past modal passive form 'might have been misunderstood' is the correct construction.
- **Incorrect Answer (b)**: 'might be misunderstood' is the passive form for a present modal ('might misunderstand'), not a past modal.
- **Incorrect Answer (c)**: This changes the modal from 'might' to 'had to', altering the meaning from possibility to necessity.
- **Incorrect Answer (d)**: This incorrectly changes the structure to a simple past passive.
66388
The director was not considering her for the role.
Answer:
She was not being considered for the role by the director.
**Rule**: For a negative sentence in the Past Continuous Tense, the passive structure is **Object + was/were + not + being + V3 + by + Subject**.
- **Correct Answer (a)**: The object 'her' becomes the subject 'She'. The passive verb form 'was not being considered' correctly reflects the negative Past Continuous tense.
- **Incorrect Answer (b)**: This incorrectly changes the tense to Present Perfect.
- **Incorrect Answer (c)**: This incorrectly changes the tense to Simple Past.
- **Incorrect Answer (d)**: This incorrectly changes the tense to Present Continuous.
66389
The company did not pay the employees on time.
Answer:
The employees were not paid on time by the company.
**Rule**: For a negative sentence in the Simple Past Tense, the passive voice structure is **Object + was/were + not + V3 + by + Subject**.
- **Correct Answer (a)**: The object 'the employees' becomes the subject. Since 'employees' is plural, 'were' is used, followed by 'not' and the past participle 'paid'.
- **Incorrect Answer (b)**: This incorrectly changes the tense to Simple Present.
- **Incorrect Answer (c)**: This incorrectly changes the tense to Past Continuous.
- **Incorrect Answer (d)**: This incorrectly changes the tense to Present Perfect.
66390
What have you been doing?
Answer:
What has been being done by you?
**Rule**: The passive voice for the Present Perfect Continuous Tense is formed with **What + has/have + been + being + V3**. This construction is extremely rare and awkward.
- **Correct Answer (a)**: This is the grammatically correct, though rarely used, passive form of the Present Perfect Continuous Tense.
- **Incorrect Answer (b)**: This changes the tense to Present Perfect.
- **Incorrect Answer (c)**: This changes the tense to Past Continuous.
- **Incorrect Answer (d)**: This changes the tense to Present Continuous.
