高中珍惜时间800字作文【一】
Time flies like an arrow before we realize it .It is known that nothing is more precious than time. The good old proverb "time is money" reminds us that time is valuable. When time goes by, it will never return. However, it is a pity that some people don't make full use of their time .They spend a lot of time in sleeping, chatting, playing computer games or other unmeaning matters. . They don't realize that wasting time is actually equal to killing themselves. They always regret not having made great achievements. One of the reasons may be they do not make good use of time. Therefore, in order to be successful, they should first get into the habit of being on time. It’s a sign of cherishing time. Don't put off what can be done today until tomorrow. Being lazy will eventually lead to failure. Don't wait, because you don't know how long it will take when you put off your plan.
高中珍惜时间800字作文【二】
For thousands of years， animals have trodden a slow path， their spirits together with the body。 But our human being\'s transportation is too fast。 The body moves but the soul is left behind。 We try to free ourselves in convenience， but we only imprison the soul。 Since we invented how to count hours， we do everything to short the time， short the deadline。 But the time saved can\'t be shorten。 Nowadays， we spend lots of time staying in front of a TV just changing the channels， while we have no time to talk with a good friend or play with our family。 We have plenty of time to search old news on the internet， while we hardly think about our life。 In the end， the only thing apparent is our loneliness。
Take your time， please。 Try to follow the natural steps and have your own clock。 Try to share your time with everybody you love， share your mind， your happiness and sadness。 Try to read the world we live in， do not only catch a quick glimpse at the society。
Someday， when we know how to spend every second in our life， we can then live our own life。
