Grammar worksheet focusing on converting sentences to passive voice, with correct answers provided.

Let's go through the worksheet and correct any errors in the provided answers, then explain the solutions clearly.

✔ Level 1: Change the sentences to passive voice

We convert active voice sentences (subject + verb + object) into passive voice:
Object + be + past participle + by subject
Note: The agent ("by" phrase) is optional but often included when relevant.

---

#### 1. Children cannot open these bottles easily.
✔ Correct answer: *These bottles cannot be opened easily by children.*
✔️ Correct — "cannot be opened" is proper passive construction with modal "can".

---

#### 2. The government built a road right outside her front door.
✘ Incorrect answer given: *"A road was build right outside her front door by the government."*
➡️ Error: "build" should be "built" (past participle).

✔ Correct answer: *A road was built right outside her front door by the government.*
✔️ Fixed: "was built" is correct passive form of "built".

---

#### 3. Mr. Ross broke the antique vase as he walked through the store.
✔ Answer: *The antique vase was broken by Mr. Ross as he walked through the store.*
✔️ Correct — passive voice with "was broken", agent included.

---

#### 4. When she arrived, the changes amazed her.
✔ Answer: *When she arrived, she was amazed by the changes.*
✔️ Correct — the subject "she" becomes the receiver of the action ("amazed").

---

#### 5. The construction workers are making street repairs all month long.
✔ Answer: *Street repairs are being made all month long by the construction workers.*
✔️ Correct — present continuous passive: "are being made".

---

#### 6. The party will celebrate his retirement.
✔ Answer: *His retirement will be celebrated by the party.*
✔️ Correct — future passive: "will be celebrated".

---

#### 7. His professors were discussing his oral exam right in front of him.
✔ Answer: *His oral exam was being discussed right in front of him by his professors.*
✔️ Correct — past continuous passive: "was being discussed".

---

#### 8. My son ate all the homemade cookies.
✔ Answer: *All the homemade cookies were eaten by my son.*
✔️ Correct — simple past passive: "were eaten".

---

#### 9. Corrosion had damaged the hull of the ship.
✔ Answer: *The hull of the ship was damaged by corrosion.*
⚠️ Note: The original uses past perfect ("had damaged"), but the passive version only needs simple past because the focus is on the result.

👉 However, technically, if we want to preserve tense, it should be:
"The hull of the ship had been damaged by corrosion."
But since the original sentence is not asking for strict tense preservation and just wants passive, the given answer is acceptable in most educational contexts.

✔ So: *The hull of the ship was damaged by corrosion.* → Acceptable (simplified).

---

#### 10. Some children were visiting the old homestead while I was there.
✔ Answer: *While I was there, the old homestead was being visited by some children.*
✔️ Correct — past continuous passive: "was being visited".

---

✔ Directions: Change the sentences below to active voice

Now convert from passive to active.

#### 11. The statue is being visited by hundreds of tourists every year.
✔ Answer: *Hundreds of tourists visit the statue every year.*
⚠️ Note: "is being visited" → active form: "tourists visit".
We drop the "being" and use simple present: "visit" (not "are visiting") because the original uses present continuous passive, which implies ongoing action, but in active voice, we simplify to general truth.

✔️ Correct: *Hundreds of tourists visit the statue every year.*

---

#### 12. My books were stolen by someone yesterday.
✔ Answer: *Someone stole my books yesterday.*
✔️ Correct — active voice: subject ("someone") + verb ("stole") + object ("my books").

---

✔ Final Summary of Corrections

| Sentence | Original Answer | Correction Needed? | Corrected Version |
|--------|------------------|--------------------|-------------------|
| 2 | A road was build... | ✘ Yes | A road was built... |
| 9 | The hull... was damaged... | ⚠️ Tense issue | Better: had been damaged (if preserving tense), but was damaged is acceptable |
| All others | ✔️ | No | Correct |
