On midsummer night, my mother and I sat on the sofa. My mother casually raised the globe on the table and pointed to London, England, and said, "There is a world-famous Greenwich Observatory here, and world time starts here."

"Time? Where is the time? Why can't I see its shadow? " I asked.

"Time comes and goes without a trace, invisible and intangible, but we can feel the traces of time." Mom replied.

What a profound and abstract concept time is. I didn't know much about "time" before, except that it was composed of seconds, minutes, hours, days, months and years. Now I understand that time will leave traces.

Think back to my past 4,000 days, from children to teenagers about to enter middle school, from books in bookcases, such as reading pictures and talking, children's pictorial, to some books with high ideological connotation, such as scientific exploration, five thousand years in China. Time left my footprints on the bookshelf.

A few days ago, my neighbor gave me several pots of colorful flowers, which really intoxicated me and made me spend a few wonderful "night among flowers". However, after five or six days, these potted flowers withered and withered. I also feel the traces of time from the changes of nature.

Time flies with traces. It flows through your fingers; Scan your words; Slip through your eyes; From your feet. In this way, I accidentally flew away. Inadvertently, have you ever known what you have done?

Time is so short and fair that different people treat it in different ways. Some people regard time as life, and every second counts, making many contributions to mankind. However, some people don't. They idle away their time, and the value of time has completely disappeared from them. What's the point of such a life?

Time is like this. If you are a smart person, please cherish every minute around you!
