请认真阅读下面短文，在短文后表格中的空白处填入适当的单词(注意：每空1个单词)。
                                                              Future and Today
    It is well known that everyone has his own dream as well as his own future. But do you know what
future really is? I have to say that future is now. That is to say we must treasure every minute now. If
we want to have a bright future, we should know how important time is and use it well.
    There is an old English saying: "Gain time, gain life." Then what's time? Time is something that we
can't see or touch, but we can feel it passing by. Time is always with us. When we are at table, time
passes; when we play, time goes by unnoticeable. We always say "Time is money", but time is even more
precious (珍贵的) than money, because when money is spent, we can earn it back. But if time is gone
away, it will never return. So, some of us even say time is priceless (无价的).
    We should always remember: future is now. For us students, we should try our best to work hard in
order to create a great future of our own. We should make the best use of every hour and be the master
of today.We should do everything before us as well as possible. And never put off what can be done today
till tomorrow.
    As we all know, "Time and tide wait for no man." If you waste today, you will regret tomorrow. So
from now on, work hard. Tomorrow will be better, and your future will be brighter. Remember: "No pains,
no gains." Today's hard work is the cause of tomorrow's harvest.
