Active And Passive Voice

Step 1: Understanding the Concept:
This question asks to convert a sentence from passive voice to active voice. The passive voice emphasizes the action's recipient, while the active voice emphasizes the doer.
The structure for this specific type of sentence is:
- Passive: It is time + for + object + to be + past participle.
- Active: It is time + to + verb (base form) + object.
Step 2: Detailed Explanation:
The given sentence is: "It is time for the bell to be rung."
- Object: the bell
- Verb (past participle): rung
Following the active voice structure:
- Start with "It is time".
- Add the infinitive "to" + base form of the verb ("ring").
- Add the object ("the bell").
This combines to form: "It is time to ring the bell."
Step 3: Final Answer:
Option (C) correctly converts the passive sentence to its active form, following the standard grammatical rule.

Step 1: Understanding the Concept:
The question requires converting an active voice sentence into a passive voice sentence. In the active voice, the subject performs the action. In the passive voice, the subject receives the action.
Step 2: Key Formula or Approach:
The formula for converting a simple past tense sentence from active to passive voice is:
Active: Subject + V2 (second form of verb) + Object.
Passive: Object (of active voice) + was/were + V3 (third form of verb) + by/with + Subject (of active voice).
Step 3: Detailed Explanation:
1. Identify Subject, Verb, and Object:
- Subject: His progress
- Verb: satisfied (V2, simple past)
- Object: me
2. Apply the Passive Voice Rule:
- The object "me" becomes the subject "I".
- The helping verb for "I" in the simple past passive is "was".
- The third form (V3) of "satisfy" is "satisfied".
- The verb "satisfied" is typically followed by the preposition "with" when referring to a state or feeling, rather than "by".
- The subject "His progress" becomes the object of the preposition.
3. Construct the Passive Sentence:
Combining these parts, we get: "I was satisfied with his progress."
4. Analyze the Options:
- (A) "I was satisfying..." - Incorrect, "satisfying" is a present participle.
- (B) "I am satisfy..." - Incorrect tense ("am") and verb form ("satisfy" instead of "satisfied").
- (C) "I was satisfied with his progress." - Correctly follows the passive voice structure for the simple past tense.
- (D) "I have to be satisfy..." - Incorrect modal verb and verb form.
Step 4: Final Answer:
The correct passive voice form is (C) "I was satisfied with his progress.".
