Question

What do you mean by Active voice and passive voice​

Answer 1

When a sentence is in the active voice, the subject of the sentence is the one doing the action expressed by the verb. In the passive voice, the subject is the person or thing acted on or affected by the verb's action. The passive voice is typically formed with a form of the verb be—such as is, was, or has been—and the past participle of the verb, as in "The ball was thrown by Jerry."

Answer 2

Here are examples of both.

Passive voice: “The deer was bothered by wolves.”
Active voice: “The wolves bothered the deer.”

Active voice takes the emphasis off of the deer. A good way I was taught to determine the difference is, if you can put “by zombies” at the end of the sentence, then it is passive voice.

Here is an example: “The homework was assigned by the teacher.”
Insert “by zombies.”
“The homework was assigned by zombies.” It still makes sense, so therefore it is passive voice.
But in active voice, it would be “The teacher assigned the homework.” If you added “by zombies” at the end of that sentence, it would not make sense.

This is what helped me memorize the difference so hopefully this can be helpful for you too.
