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.
212
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.
213
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.
214
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'.
215
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.
216
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.
217
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.
218
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.
219
The manager did not sign the documents.
Answer:
The documents were not signed by the manager.
**Rule**: For a negative sentence in the Simple Past Tense, the passive voice structure is **Object + was/were + not + V3 + by + Subject**.
- **Correct Answer (b)**: The object 'the documents' becomes the subject. Since 'documents' is plural, 'were' is used, followed by 'not' and the past participle 'signed'.
- **Incorrect Answer (a)**: This incorrectly changes the tense to Simple Present.
- **Incorrect Answer (c)**: This incorrectly changes the tense to Present Perfect.
- **Incorrect Answer (d)**: This incorrectly changes the tense to Past Continuous.
220
The company has to implement the new safety procedures.
Answer:
The new safety procedures have to be implemented by the company.
**Rule**: When the active sentence uses 'has to'/'have to', the passive form is **Object + has/have to + be + V3**. The choice between 'has' and 'have' depends on the new subject.
- **Correct Answer (b)**: The object 'the new safety procedures' becomes the subject. Since 'procedures' is plural, it takes 'have to be', followed by the past participle 'implemented'.
- **Incorrect Answer (a)**: 'have been implemented' is the passive of the Present Perfect Tense.
- **Incorrect Answer (c)**: 'had to be' incorrectly changes the tense to the past.
- **Incorrect Answer (d)**: 'are to be' implies a plan, not the necessity of 'have to'.
