"Would you mind turning off the lights when you leave?" - Request: "Would you mind..." This part politely asks for a favor.- Command: "...turning off the lights when you leave?" This part directly instructs the person to perform a specific action. This sentence is a bit more subtle than the previous example, but it still effectively combines a request with a command. It's a polite way to ask someone to do something, while also making it clear that you expect them to follow throughout.
