Language – The Passive Voice (18 Points) Change each sentence into the Passive Voice. (6x3=18 pts.) 1. Students review all the material before the exam. 2. The police caught the thief near the city gallery. 3. One of these days the government will send new computers to schools. 4. She did not complete the last assignment on time. 5. Will our school organize the final championship this year? 6. What did the students bring for the project?

🎯 What You'll Learn

  • correctly transform active sentences to passive voice
  • understand proper placement of by-agent phrases in passive constructions
  • recognize when passive voice is appropriate in English grammar

Prerequisites: understanding of active voice, knowledge of auxiliary verbs (be + past participle), familiarity with agent identification

💡 Quick Summary

Great news — passive voice transformations follow a reliable pattern once you spot the key ingredients in each sentence! The core idea is that in active voice, the subject *does* the action, but in passive voice, the original *object* gets promoted to the subject position — so ask yourself, "what or who is *receiving* the action in each sentence?" From there, think about what happens to the verb: it always becomes a form of "to be" plus the past participle, and the tense of "to be" needs to match the tense of the original sentence. Here's something interesting to puzzle over: what do you think happens to negative sentences and questions — do those extra words like "not" or the question structure just disappear, or do they need to show up somewhere in the passive version too? Also consider where the original subject ends up — it doesn't vanish entirely, so where would it naturally fit in the new sentence? Try working through one sentence at a time, identifying the object first, then the tense, and you'll likely find the rest falls into place. You've got this — passive voice is really just a formula in disguise! 🌟

1. What We're Solving

You need to take 6 active voice sentences and flip them into passive voice. Each sentence has a different tense or structure.

2. The Approach

Why do we use the Passive Voice?

In active voice, the subject does the action → "The cat ate the fish." In passive voice, the subject receives the action → "The fish was eaten by the cat."

The Master Formula:

``` OBJECT → becomes new Subject + TO BE (correct tense) + PAST PARTICIPLE + (by + agent) ```

Tense Guide for "To Be":

| Original Tense | "To Be" in Passive | |---|---| | Simple Present | am/is/are | | Simple Past | was/were | | Simple Future (will) | will be | | Negative | same rules + not | | Question | invert the auxiliary |

3. Step-by-Step Solution

✏️ Sentence 1:

"Students review all the material before the exam." (Simple Present)

  • Object = all the material → becomes the new subject
  • To Be = is (material is singular)
  • Past Participle = reviewed
  • Agent = by students
Result: All the material is reviewed by students before the exam.

---

✏️ Sentence 2:

"The police caught the thief near the city gallery." (Simple Past)

  • Object = the thief → new subject
  • To Be = was (thief is singular, past tense)
  • Past Participle = caught
  • Agent = by the police
  • Keep the place (near the city gallery) at the end
Result: The thief was caught by the police near the city gallery.

---

✏️ Sentence 3:

"One of these days the government will send new computers to schools." (Simple Future)

  • Object = new computers → new subject
  • To Be = will be (future passive always uses "will be")
  • Past Participle = sent
  • Keep = to schools stays (it's a recipient, not removed)
  • Agent = by the government
Result: New computers will be sent to schools by the government one of these days.

---

✏️ Sentence 4:

"She did not complete the last assignment on time." (Simple Past, NEGATIVE)

  • Object = the last assignment → new subject
  • To Be = was + not (keep the negative)
  • Past Participle = completed
  • Agent = by her
Result: The last assignment was not completed by her on time.

---

✏️ Sentence 5:

"Will our school organize the final championship this year?" (Future, QUESTION)

  • Object = the final championship → new subject
  • Structure = Will + subject + be + past participle?
  • Past Participle = organized
  • Agent = by our school
  • Keep = this year at the end
Result: Will the final championship be organized by our school this year?

---

✏️ Sentence 6:

"What did the students bring for the project?" (Simple Past, WH-QUESTION)

  • Object = what → becomes "What" at the start (WH-words stay at the front)
  • To Be = was
  • Past Participle = brought
  • Agent = by the students
Result: What was brought by the students for the project?

4. The Answers

| # | Passive Voice Sentence | |---|---| | 1 | All the material is reviewed by students before the exam. | | 2 | The thief was caught by the police near the city gallery. | | 3 | New computers will be sent to schools by the government one of these days. | | 4 | The last assignment was not completed by her on time. | | 5 | Will the final championship be organized by our school this year? | | 6 | What was brought by the students for the project? |

5. 🧠 Memory Tip

Think of the passive voice as "flipping a pancake" 🥞

  • The bottom (object) comes to the top (subject)
  • You add "to be" as your cooking spray
  • Sprinkle the past participle on top
  • The original subject quietly moves to the end with "by"
---

The key is always finding who receives the action first — that's your new subject! 🌟

⚠️ Common Mistakes to Avoid

  • incorrect placement of by-agent phrase (before adverbials instead of after)
  • omitting or misplacing auxiliary verbs
  • failing to convert the main verb to past participle form
  • confusion with word order when multiple adverbial phrases are present
