    18.(2025 鹰潭二模) Have you ever felt like time is slipping away too fast? (1)    But is time really speeding up,or is it just how we perceive it?
    Psychologists explain that our sense of time is shaped by our experiences.When life falls into a repetitive routine,time appears to rush by.In contrast,when we engage in new and exciting activities,time seems to slow down.(2)   
    Whether it's traveling to unfamiliar places,exploring different neighborhoods,or picking up a new hobby,trying new things creates vivid and lasting impressions.Learning something new,such as a language,an instrument,or a skill,enriches our days and makes them feel more substantial.(3)    Therefore,instead of rushing through the day,we should slow down and observe our surroundings.When we notice the changing seasons,listen to conversations,and appreciate small details,we become more aware of the present.Practicing mindfulness improves our memory and helps us feel more in control of time.
