Way to differentiate between active and passive voice
Active and passive voice can be differentiated from each other by asking the following questions
- What/who is doing a certain task?
- Which is the verb of the sentence?
- Is the subject of the sentence doing any action?
When the last question’s answer is Yes, then the sentence is to be considered in an active voice. The sentence is regarded as the passive voice when the answer is no.
