Step 1: look for a grammar signal among the pieces – here “把”, so the frame is (subject) + 把 + object + verb + something more. Step 2: “请你” (please, you) opens a request, so it goes first. Step 3: the thing acted on, “空调” (the air conditioner), comes right after “把”, and the verb with its result, “关了” (switch off), ends the sentence. Result: “请你把空调关了。” (Please switch off the air conditioner.) “请你关了空调把” is impossible: in a 把 sentence the object always comes before the verb.
