Which sentence is in the active voice?

The girl jumped on the trampoline.

The cake will be served to the queen.

Is it the first one? But, if so, then how can the second sentence be written in the active voice?

Yes, the first one, because the subject DOING the action of the verb?

To make the second one active, you'll need to say who is doing the serving. Who will you say?

Thank you. My school gave me these sentences and asked me to say which one is in the active voice. I was just curious to know how the second sentence could be written in the active voice.

You're welcome.

Just remember that to be ACTIVE, the subject has to be DOING the action of the verb!

Yes, the first sentence "The girl jumped on the trampoline" is indeed in the active voice. In the active voice, the subject of the sentence performs the action.

To write the second sentence "The cake will be served to the queen" in the active voice, you would need to rephrase it so that the subject of the sentence is performing the action. One possible active voice rephrasing could be: "The queen will serve the cake." In this rephrased sentence, "the queen" is the subject and "serve" is the verb, showing that the queen is performing the action of serving the cake.
