Last week, Teacher Ma taught us about clocks and watches. On Sunday afternoon, I learned to dial the time with a small alarm clock at home and found a rule.
When I set the alarm clock on the table at 3 o'clock, I turned around and accidentally found that the alarm clock reflected in the glass mirror opposite the alarm clock was not 3 o'clock. It took me a long time to open my eyes before I recognized that the alarm clock pointed to 9 o'clock. I was curious. When I set the time to 1, I found that the alarm clock in the mirror pointed to 1 1. The alarm clock in the mirror pointed to 8: 30, and I tried to observe it several times. I was surprised to find a rule that the actual time and the two times in the mirror add up to 12 hour.
You can try it if you are interested. Except for 12 hour, the sum of other actual time and looking in the mirror time is 12 hour. Moreover, using this rule can help us quickly and accurately identify the time in the mirror, and we can also quickly know the actual time by looking at the time in the mirror.
No wonder my mother often tells me that "you can learn things by paying attention everywhere", and I finally understand the meaning of this sentence.
