What is time? Nobody sees it and nobody catches it. But everyone can feel it passing by. Time is always 
with us in life. When we are at the table, time passes away. When we talk, time slips away (溜走) in front of us.
And when we play with friends, time goes by unnoticeably (不注意地) .      
       Time is fair (公平) to each one of us. If you make the best use of it, time will give you a lot. Otherwise you
will miss a lot.  The most important is that time will not be found again.       
       Time is becoming more and more important to us today. You can always hear people say, " Time is money,
Time is life. " It warns us not to waste (浪 费) any time.       
       My friends, we must keep in mind the saying, "Time and tide wait for no man." Now we are all young.  It is
high time for us to learn more.  We must try our best and be the masters of time.
