Hello everyone, and welcome to On Your Mark’s English.
Today is Thursday, and this is Common Mistakes! ❌
We’re fixing a mistake that happens because of direct translation: Open vs Turn On.
Many students say, “Please open the light.” 💡This is incorrect. ❌
🚪 OPEN / CLOSE
We use open and close for physical objects that have an opening.
Examples:
• Open the door.
• Close the book.
• Open the window.
🔌 TURN ON / TURN OFF
We use turn on and turn off for electronics or anything with a switch or power.
Examples:
• Turn on the light.
• Turn off the TV.
• Turn on the AC.
🧠 Remember
If it uses electricity, don’t open it. Turn it on.
