Active and Passive Voice Test-1

• The sentence "TV / invent / Baird" needs to be converted into passive voice.
• Identify the tense: The sentence implies a past event, so we'll use the past simple tense.
• Active voice: "Baird invented the TV."
• Passive voice: "The TV was invented by Baird."
• In passive constructions, the object "TV" becomes the subject, and "invented" turns into "was invented."

The sentence 'Finish the work in time' is in active voice. To convert it to passive voice, we structure it as 'Let the work be finished in time.'

Option A correctly uses the passive construction without introducing unnecessary agents.

To form the passive voice, the object of the active sentence becomes the subject of the passive sentence. Follow these steps:

• The active sentence is: "Cows produce milk."
• The subject "cows" becomes the agent in the passive voice, often omitted.
• The object "milk" becomes the subject in the passive voice.
• Use the verb "to be" in the present simple tense ("is") to match the tense of the original verb.
• Add the past participle of the main verb, "produced."
• Resulting sentence: "Milk is produced (by cows)."

A verb is used to express an occurrence, action, or state. It is the grammatical center of the predicate in a sentence.
An auxiliary verb is a verb which is used in the formation of tenses, moods, tones, etc.
The passive voice and indicates the use of the past participle form of the verb.
Coffee is grown in Brazil.

To form the passive voice, we need to use the appropriate tense of the verb 'to be' followed by the past participle of the main verb. In this case, the correct structure is:

Subject (chopsticks) + verb 'to be' in present simple (are) + past participle (used).

• Option A is correct because it uses the present simple passive voice, which is appropriate for general truths or habitual actions.
• Option B is incorrect because 'were used' suggests a past action, but the original sentence implies a general or present truth.
• Option C is incorrect because 'have been used' is in the present perfect tense and implies an action that started in the past and continues to the present, which is not intended here.
• Option D is incorrect because it uses the active voice instead of the passive voice.

Thus, the correct answer is A.

To form the passive voice, we use the structure:

• subject + verb (am/is/are) + past participle of the main verb.

In this case, 'plants' is the subject, and since it is plural, we use 'are.' The past participle of 'water' is 'watered.' Therefore, the correct sentence is:

'Plants are watered every day.'

This sentence uses the present simple passive tense to indicate a daily routine.

- To form the passive voice, identify the object of the active sentence, which becomes the subject of the passive sentence.
- The sentence "the policeman arrested the robber yesterday" changes to passive by making "the robber" the subject.
- Use the past simple tense for the verb "arrest" since the action occurred yesterday.
- The correct passive construction is: "The robber was arrested by the policeman yesterday."

The passive voice in the present continuous tense is used here. The subject 'injured marines' is acted upon by the verb 'are being taken', indicating an ongoing action.

- The original sentence is in the past continuous tense: "The boys were playing Cricket."
- To convert this to the passive voice, we need to use the structure: "was/were being + past participle."
- Thus, "Cricket was being played by the boys" is the correct passive form.
