Time is life
A proverb says,"Time is life." Why?Because when time is gone,it will never return.This is the reason why we must value time.
It goes without saying that the time for our study and work is unusually limited.So,even an hour is extremely precious.We should make full use of our time to do useful things.
As a student,I must make efforts to engage in my study so as to serve our nation and people in the future.But it is a pity that there are a lot of people who do not know the importance of time.They do not realize that wasting time is equal to wasting a part of their valuable life.
In a word,we should form the good habit of saving time.Do not put off what can be done today till tomorrow.翻译：
俗话说：“时间就是生命”.为什么呢?因为时间一去不复返.这也是我们必须节约时间的原因.不消说,我们用于学习和工作的时间是有限的,因此,哪怕是一小时也是极其宝贵的.我们应当充分利用时间去做有用的事情.作为一名学生,我要努力专心学习以便将来为国为民服务.遗憾的是还有许多人并不知道时间的重要,他们还没有意识到浪费时间就等于浪费他们宝贵的生命.
一句话,我们应养成节约时间的好习惯.不要把今天能完成的事拖到明天.
