Back to the Quiz ↑Use this list to check your answers and to revise. It shows all 20 active-versus-passive pairs from the quiz. Read the active sentence, cover the right-hand column, name the tense and the doer, and say the passive version aloud before you peek. Sentence transformations are best learned in short, repeated sessions rather than in one long read, so come back to this table after a day and again after a week.

Practising voice changes alphabetically is a simple way to stay organised. When you study one letter at a time, you meet a manageable group of verbs, you can track your progress and you can see how many of the transformations you already control. This quiz focuses on verbs starting with S that appear often in conversation, books and exams, including sentences such as The athletes should stretch their muscles. → Their muscles should be stretched by the athletes. · The axe split the log. → The log was split by the axe. · The chef will slice the melon. → The melon will be sliced by the chef..
English has fewer common verbs that begin with S than with letters such as A, S or T. That is why this page has 20 questions instead of 50. Every sentence included here is a genuine transformation pair built around a real verb, so your time is spent only on grammar worth learning.
Most S verbs are regular, so the participle is simply the -ed form. Knowing the tense table below turns a sentence you have never transformed into one you can rewrite on sight.
Grammar papers love the ten tenses in the cheat sheet. Practising by letter gives you steady, focused revision before a test instead of one giant exercise the night before.
Reading passages and exam questions reward learners who can flip a sentence both ways. Each transformation you master here makes the next chapter or test easier to follow.
Voice is the shape a sentence takes around its verb. In the active voice the subject performs the action: The dog chased the cat. The doer comes first, the verb carries the tense and the receiver comes last. In the passive voice the receiver moves to the front, the verb becomes a form of be plus the past participle, and the doer - if it matters at all - hides at the end after by: The cat was chased by the dog.
Nothing about the event changes when you switch voice. The same cat was chased in both sentences; only the spotlight moves. That is why examiners can ask you to convert between the two voices and expect the meaning to stay exactly the same: same tense, same participants, same facts - just a different order and a different verb shape. This quiz drills that single skill until it feels automatic.
| Active | Passive | What Moved |
|---|---|---|
| The chef cooked the meal. | The meal was cooked by the chef. | the meal to the front; verb to was + cooked |
| Riya writes a poem. | A poem is written by Riya. | a poem to the front; verb to is + written |
| They will announce the results. | The results will be announced by them. | the results to the front; verb to will be + announced |
| Someone has stolen the jewellery. | The jewellery has been stolen. | the jewellery to the front; the unknown doer dropped |
Neither voice is better. Good writers choose the voice that puts the right information first.
When the doer matters and you want energy: The goalkeeper saved the penalty. Active sentences are usually shorter, clearer and easier to read, which is why they dominate stories, headlines and everyday speech.
When the receiver matters more, or the doer is unknown: The penalty was saved. News reports, instructions and science writing use the passive to keep the important noun in the spotlight and to sound objective.
Skilled writers flip between voices: The museum was built in 1901 and the city still funds it today. Notice how the passive keeps the museum as the topic while the active handles the city. Control of both voices is what examiners reward.
When two options both look possible in the quiz, work through these five steps before you answer.
Twelve lines cover almost every passive sentence on school lists and exams. Learn the pattern and the example together - the pattern tells you what to build, the example tells you what it should sound like.
| Tense | Passive Form | Example |
|---|---|---|
| Simple present | am / is / are + past participle | She writes a letter. → A letter is written by her. |
| Present continuous | am / is / are + being + past participle | They are building a house. → A house is being built by them. |
| Present perfect | has / have + been + past participle | He has posted the letter. → The letter has been posted by him. |
| Simple past | was / were + past participle | The chef cooked the meal. → The meal was cooked by the chef. |
| Past continuous | was / were + being + past participle | They were repairing the road. → The road was being repaired by them. |
| Past perfect | had + been + past participle | She had cleaned the room. → The room had been cleaned by her. |
| Simple future | will be + past participle | He will sign the form. → The form will be signed by him. |
| Future perfect | will have been + past participle | She will have sent the report. → The report will have been sent by her. |
| Modals | modal + be + past participle | You must obey the rules. → The rules must be obeyed. |
| Going to | am / is / are + going to be + past participle | They are going to move the table. → The table is going to be moved by them. |
| Past participle | use the third form (V3), never the second | write → written (not wrote), drink → drunk (not drank) |
| The doer | add by + the doer of the action | by the chef, by Riya, by the students |
Every passive sentence on this page is powered by one small piece of grammar: the past participle, the third form of the verb. Regular verbs are easy - cook, cooked, cooked. The trouble comes from the short list of irregular verbs that appear constantly in exam questions. Learn these eight pairs once and a whole family of distractors stops working on you.
| Base (V1) | Past Simple (V2) | Past Participle (V3) | Passive Example |
|---|---|---|---|
| write | wrote | written | The novel was written in 1962. |
| break | broke | broken | The window was broken by the boys. |
| drink | drank | drunk | The milk was drunk by the cat. |
| steal | stole | stolen | The ring was stolen last night. |
| give | gave | given | A speech was given by the principal. |
| take | took | taken | The tools had been taken by the gardener. |
| sing | sang | sung | The anthem was being sung by the choir. |
| drive | drove | driven | The bus will be driven by the new driver. |
Wrote, drank and stole are past-simple forms. After any form of be you need V3: written, drunk, stolen. Say the participle out loud as you answer.
Written is used in is written, was written, has been written and will be written. Learn the participle once and every tense opens up.
The trap is not only irregulars: The letter was posted by him is right, but was post or was posting are wrong. Match be + third form every time.
The participle never changes, but be does: The letters were written, the letter was written. Find the new subject first, then choose is/are/was/were.
The passive voice gives you a choice the active voice does not: the doer can stay or go. Exam conversions usually keep it - The meal was cooked by the chef - but real writing drops the by-phrase whenever the doer is unknown, obvious or unimportant. Knowing when to keep it is a writing skill; knowing it must match the original doer is an exam skill.
If the question says convert the sentence, every part of the meaning should survive - including the doer. The thief was caught by the police keeps all three parts.
My bicycle was stolen needs no by-phrase - nobody knows the thief. The criminals were arrested already names the receiver as the topic.
The doer becomes an object after by: by him, by her, by them, by us. They will announce the news becomes The news will be announced by them.
The doer is introduced by by, not with or from. A sentence like The cake was made from my mother fails the conversion even though it sounds close.
Voice transformation appears throughout school and competitive exams. Grammar sections ask you to rewrite a sentence in the other voice, error-spotting tests hide a wrong participle or a wrong be-form inside an otherwise correct line, and writing tasks reward candidates who can choose the voice that serves the sentence. A few habits make the marks much easier to collect.
Fifteen to twenty minutes a day is enough. Follow this plan, then move on to the next letter.
Teachers, tutors and parents can turn this letter quiz into a longer learning session with these simple ideas.
Half the class writes active sentences with S verbs, the other half converts them on mini-whiteboards. Teams swap papers and mark each other using this page as the answer sheet.
Give out a newspaper page. Students hunt for five passive sentences, underline the be-form and participle, and report which doers were dropped - and whether dropping them was fair.
Open this page on a projector, split the class into teams and award a point for each correct answer. The sticky score bar makes tracking easy.
Each morning, pick one row of the tense table: everyone writes one active and one passive sentence using that tense before the register. By June the whole table lives on the wall.
This page has 20 questions, all on one page and split into 4 sets of up to 5. Each question shows an active sentence whose main verb starts with S and four possible passive versions; you choose the passive sentence that is correct.
Only a limited number of common English verbs begin with S. Instead of padding the page with rare or invented sentences, this quiz includes 20 real active-versus-passive pairs that people actually use.
In an active sentence the subject does the action: The chef cooked the meal. In a passive sentence the object of the action moves to the front and the verb becomes be + past participle: The meal was cooked by the chef. Both sentences describe the same event - they simply put the spotlight on different parts of it.
Follow four moves. One: take the object of the active sentence and put it at the front. Two: add the correct form of be for the tense (is, was, has been, will be and so on). Three: change the main verb to its past participle. Four: add the doer at the end with by. So Riya writes a poem becomes A poem is written by Riya.
The past participle is the third form of the verb (V3): write-wrote-written, cook-cooked-cooked, drink-drank-drunk. Every passive sentence is built with be + this third form. The single most common passive mistake is using the second form instead - sentences like The letter was wrote by him are wrong, because wrote is the past simple, not the participle.

Four errors appear again and again. Using the wrong form of be for the tense (The meal is cooked by the chef yesterday). Using the past simple instead of the past participle (was wrote instead of was written). Matching be to the wrong number (The letters is delivered). And mixing up been and being: has been written is perfect, is being written is continuous - they are not interchangeable.
Use it when the doer is unknown, obvious or unimportant (My bicycle was stolen last night), when you want the receiver of the action to be the topic of the sentence (The bridge was opened in 1932), and in formal, scientific or report writing where processes matter more than people (The samples were tested twice).
School students, English learners and anyone preparing for exams such as SAT, IELTS, TOEFL, Cambridge tests or school grammar papers, where voice-transformation questions appear often. Teachers and parents can also use it as a quick classroom or homework activity.
