Question

Put the following sentences in to the Passive voice: they built this house in 1950. 2. Somebody locked the front door. 3. Someone broke my pen last night. 4. They punished the boy for that. They finished their work in time.

Answer 1

1.This house was built in 1950.
2. The front door was locked (/by somebody/?).
3.My pen was broken last night.
4.The boy was punished.
5.Their work was finished in time.

Answer 2

To convert the given sentences into the passive voice, we need to identify the subject, verb, and object in each sentence and rearrange them accordingly. Here are the sentences in the active voice and their passive voice equivalents:

1. Active: They built this house in 1950. Passive: This house was built in 1950 by them.

2. Active: Somebody locked the front door. Passive: The front door was locked by somebody.

3. Active: Someone broke my pen last night. Passive: My pen was broken last night by someone.

4. Active: They punished the boy for that. Passive: The boy was punished for that by them.

5. Active: They finished their work in time. Passive: Their work was finished in time by them.

In the passive voice, the object of the active sentence becomes the subject, and the subject of the active sentence becomes the object (if included in the passive sentence). Additionally, the verb is changed to its past participle form and the agent (the doer of the action) is introduced with the preposition "by" (if needed and known).

Please note that in some cases, the agent (the doer of the action) may not be mentioned or may be omitted if it is not important or not known.
