How do you know if you have an alarm clock in the morning?

If you want to make sure whether the alarm clock is off in the morning, there are several ways to try:

1. Memory method: Try to recall the scene when you get up in the morning, see if you can remember the sound of the alarm clock, or realize that you turned off the alarm clock.

2. Check the mobile phone: Check the alarm clock settings on the mobile phone to see if the alarm clock has been turned off.

3. Check the bedside: See if there is an alarm clock by the bedside, or if there is a closed alarm clock nearby.

If none of the above methods can confirm whether you have turned off the alarm clock, the best way is to set a new alarm clock, and be sure to check whether the old alarm clock has been turned off before turning off the new alarm clock. This will ensure that you won't cause unnecessary trouble because you forgot to turn off the alarm clock in the morning.
