English has two voices: active and passive. The active voice is used when the subject of the sentence does the action. For example: My mom sings that song. The passive voice is used when we focus on the object of the sentence. For example: That song is sung by my mom.
When it is important to know who does the action, we use by. The noun that follows by is called the “agent.” My mom was the subject in the active sentence, but it becomes the agent in the passive sentence.
When the agent is unknown, or unimportant to the meaning of the sentence, we do not use by. For example : This sweater is made in China.
The passive voice is often used: When we talk about art, science, or literature. For example : The scientific method is used for experiments. To explain directions and instructions. For example : Baseball is played with nine players on the team. In news reports and academic writing. For example : The environment is studied by many scientists.
