Active & Passive Voice — Set 4
Questions 31–40 of 140
Change to Passive Voice: 'He always keeps his promise.'
Correct Answer: A. His promise is always kept by him.
Simple Present Passive = is/am/are + past participle. 'Keeps' → 'is kept'. Frequency adverb 'always' is placed between 'is' and 'kept'. The possessive 'his' with promise is preserved. 'He' becomes 'by him' in the passive construction.
Change to Passive Voice: 'The police arrested three criminals yesterday.'
Correct Answer: B. Three criminals were arrested by the police yesterday.
Simple Past Passive = was/were + past participle. 'Arrested' → 'were arrested' (three criminals is plural). 'Yesterday' is a definite past time marker confirming Simple Past tense. 'The police' → 'by the police'. Time adverb 'yesterday' is retained.
Change to Passive Voice: 'She will not help you.'
Correct Answer: B. You will not be helped by her.
Negative Future Passive = will not be + past participle. 'Will not help' → 'will not be helped'. The negative 'not' is placed between 'will' and 'be'. 'Help' past participle is 'helped'. 'She' → 'by her'. 'You' (object) becomes the passive subject.
Change to Passive Voice: 'He knows the answer.'
Correct Answer: C. The answer is known by him.
Simple Present Passive of stative verb 'know' = is/am/are + past participle. 'Knows' → 'is known'. Stative verbs like know, like, love, hate use Simple Present/Past passive, not continuous. 'By him' retains the agent. 'The answer' becomes the subject.
Change to Passive Voice: 'They play cricket in this ground.'
Correct Answer: A. Cricket is played in this ground by them.
Simple Present Passive = is/am/are + past participle. 'Play' → 'is played'. Since 'they' is a general subject, 'by them' can be omitted optionally. Location adverbial 'in this ground' is retained in the passive. Cricket (singular) takes 'is'.
Change to Passive Voice: 'She has written three novels.'
Correct Answer: C. Three novels have been written by her.
Present Perfect Passive = have/has + been + past participle. 'Has written' → 'have been written' (three novels is plural, so 'have'). 'Written' is already the past participle of 'write'. 'She' → 'by her'. The plural subject 'three novels' requires 'have'.
Change to Passive Voice: 'He has completed the assignment.'
Correct Answer: B. The assignment has been completed by him.
Present Perfect Passive = have/has + been + past participle. 'Has completed' → 'has been completed'. 'Assignment' is singular, so 'has' is used (not 'have'). 'Complete' → 'completed' (past participle). 'He' → 'by him'. Do not omit 'been'.
Change to Passive Voice: 'They have built a new hospital.'
Correct Answer: A. A new hospital has been built by them.
Present Perfect Passive = have/has + been + past participle. 'Have built' → 'has been built'. Although plural 'they' uses 'have', the passive subject 'a new hospital' (singular) governs the auxiliary — 'has been built'. 'Built' is the past participle of 'build'.
Change to Passive Voice: 'The scientist has discovered a new planet.'
Correct Answer: B. A new planet has been discovered by the scientist.
Present Perfect Passive = has/have + been + past participle. 'Has discovered' → 'has been discovered'. The passive subject 'a new planet' is singular, so 'has' is used. 'Discovered' is both past tense and past participle. The agent 'the scientist' is retained.
Change to Passive Voice: 'I have posted the letter.'
Correct Answer: A. The letter has been posted by me.
Present Perfect Passive = has/have + been + past participle. 'Have posted' → 'has been posted' (letter is singular → 'has'). 'Post' → 'posted'. 'I' → 'by me'. The tense shifts from 'have posted' (subject I) to 'has been posted' (subject letter - singular).
