Answer» Correct Answer - Option 4 : use of verb form
The correct answer is use of verb form.
- The passive voice is used when we want to emphasize the action (the verb) and the object of a sentence rather than subject.
- When changing an active sentence to a passive sentence, the tense of the verb changes.
- Every passive sentence contains a “be” verb.
- To change an active verb to a passive verb, use the correct form of “be” and the past participle of the original active verb.
- For example, Eat becomes eaten.
- Thus, it can be concluded that while learning about the passive voice form, students majorly learn about use of verb form.
When we know who the subject is, we put it at the end with by. We call this an agent. - Though a student learns the use of 'by' as well while forming a sentence in passive voice, but primarily and most importantly he learns the use of verb form.
- There are some sentences where we don't even need 'by'.
This means that the subject is either less important than the action itself or that we don’t know who or what the subject is. - For example: My laptop was stolen.(It is the passive voice of - Someone stole my laptop)
