voice

=Voice:= In grammar, the **voice** of a verb describes the relationship between the action (or state) that the verb expresses and the participants identified by its arguments (subject, object, etc.). When the subject is the agent or actor of the verb, the verb is in the **active voice**. When the subject is the patient, target or undergoer of the action, it is said to be in the **passive voice**.

Active Voice- In sentences written in active voice, the subject performs the action expressed in the verb. the verbs "bit, will present, and ate" are all in the active voice.
 * **The dog** //bit// **the boy**.
 * **Frank** //will present// **his research** to the class.
 * **The cat** //ate// **the mouse.**

Passive Voice- In sentences written in passive voice, the subject receives the action expressed in the verb. the verbal phrases "was bitten, will be presented, and was eaten" are passive.
 * **The boy** //was bitten by// **the dog**.
 * **Research** //will be presented by// **Frank** to the class.
 * **The mouse** //was eaten// **by the cat.**
