Question patterns exams keep repeating
Taken from previous-year papers. If a pattern is marked "very common", expect to see it in your exam.
Change active to passive
very commonA plain sentence with a doer, a verb and an object; the options are passive versions.
Find the tense, then build its passive: object first + be-form + V3.
Make the be-word match the new subject and put the doer after 'by'.
Change to passive: The workers have painted the gate.
'have painted' is present perfect
Passive pattern: has/have been + V3
New subject 'the gate' is singular, so 'has'
Answer: The gate has been painted by the workers.
Change passive to active
very commonThe sentence already has 'was', 'has been' or 'is being' + V3, and asks for the active form.
The first helping word shows the tense (had been = past perfect).
Make the 'by' doer the subject; if there is no doer, use 'They'.
Change to active: The walls had been whitewashed by the masons.
'had been' shows past perfect
'the masons' becomes the subject
Past perfect active: had + V3
Answer: The masons had whitewashed the walls.
Orders (Let ...)
commonAn order with no subject, like 'Shut the door', and the answer starts with 'Let'.
Use Let + object + be + V3.
For a 'Do not' order use Let + object + not be + V3.
Change to passive: Switch off the mobile.
It is an order, so start with 'Let'
The object 'the mobile' comes next
Then be + V3
Answer: Let the mobile be switched off.
Requests and advice
commonThe sentence has 'please' or 'kindly', or gives advice or a warning.
Use 'You are requested to' for please, 'You are advised to' for advice, 'You are warned not to' for a warning.
Keep the rest of the sentence the same.
Change to passive: Please post this letter today.
'Please' shows a request
Start with 'You are requested to'
Then the base verb and the rest
Answer: You are requested to post this letter today.
Questions with Who / Whom / What
commonA question that starts with 'Who', 'Whom' or 'What'.
For 'Who' use 'By whom' + helping verb + new subject + V3.
Keep question order: helping verb before the subject.
Change to passive: Who broke the window?
'Who' is the doer, so start with 'By whom'
Past tense, so use 'was' + V3
Question order: was the window broken
Answer: By whom was the window broken?
Dropping a vague doer
commonThe subject is 'someone', 'people' or 'they', and one option has no 'by ...' part.
Convert the sentence as usual.
Drop vague doers like 'by someone'; keep clear ones like 'by the committee'.
Change to passive: Someone has switched off the fans.
'Someone' is vague, so drop it
Present perfect passive: have been + V3
The subject 'fans' is plural, so 'have'
Answer: The fans have been switched off.
'being' or 'been'?
very commonThe options differ only in 'is being', 'is been' or 'was being'.
'being' goes with continuous tenses (is/was being + V3).
'been' goes with perfect tenses (has/had been + V3).
Change to passive: The engineers were repairing the bridge.
'were repairing' is past continuous
Passive continuous needs 'being'
The subject 'the bridge' is singular, so 'was'
Answer: The bridge was being repaired.
Spot the voice error
occasionalA sentence has a faulty passive like 'has being launched' or 'must obeyed'; you must find the error.
The word after 'be' must be V3.
Check 'being' vs 'been' and whether the verb matches the subject.
Find the error: 'The new scheme has being launched / by the government / without much publicity.'
Present perfect passive = has been + V3
'has being' mixes up the two words
The error is in part 1
Answer: it should be has been launched
