Subject-Verb Agreement: Understanding Active & Passive Voice

Yes, in active voice sentences, the subject performs the action of the verb. In such sentences, the subject is placed before the verb and the verb is in the active form. For example:

The boy kicked the ball. (Here, the boy is performing the action of kicking.)

The girl sang a song. (Here, the girl is performing the action of singing.)

The man wrote a letter. (Here, the man is performing the action of writing.)

In passive voice sentences, however, the subject receives the action of the verb. In such sentences, the subject is placed after the verb (which is in the passive form) and is preceded by the word 'by'. For example:

The ball was kicked by the boy. (Here, the ball is receiving the action of being kicked by the boy.)

A song was sung by the girl. (Here, the song is receiving the action of being sung by the girl.)

A letter was written by the man. (Here, the letter is receiving the action of being written by the man.)

So, in active voice sentences, the subject performs the action of the verb, while in passive voice sentences, the subject receives the action of the verb.
