Time is valuable but limit. There’s a famous saying, “Time is money”, this shows the

important of time. When time has gone, it will never return back. It’s a pity when many people

make poorly use of time. They spend their precious time oversleeping, drinking and traveling.

They don’t realize wasting time is equal to waste part of their life. They always regret having

made a little achievement so far. Therefore, we should form the habit of valuing time. Don’t put off

that can be done today until tomorrow. Laziness will not only bring us failure, but also lead us on

poverty and even death.

We are warned by our teachers not to waste time because time 26 will never return. I think it quite 27. What does time look 28 ? Nobody knows, and we can’t see it or touch it and no 29 of money can buy it. Time is abstract(抽象的), so we have to  30 about it.

Time passes very quickly. Some students say they don’t have 31 time to review their lessons. It is 32 they don’t know how to make use of their time. They waste it in going to theatres or playing, and 33 other useless things. Why do we study everyday? Why do we work? Why do most people 34 take buses instead of walking? The answer is very 35 .We wish to save time because time is36.

Today we are living in the 21^st century. We 37  time as life. When a person dies, his life ends. Since life is short, we must 38 our time and energy to our study so that we 39 be able to work and live well in the future. Laziness is the 40 of time, for it not only brings us 41 , but also does other 42 to us. If it is necessary for us to do our work today, 43 we do it today and not 44 it until tomorrow. Remember that time is much more 45.

Once many years ago, I pulled a family out of a burning car somewhere in Wyoming. Last week I received a telephone call from a woman who could not stop crying as she told me that one of my stories had saved her son from committing suicide. In closing she called me a hero.

That got me thinking about what a hero is. Was I a hero because I pulled a family from a burning car? If so, how could I be a hero just because I wrote a story that saved someone’s life?

Today I looked up the word “hero” in the dictionary to see exactly what it meant. It read “a person who does something brave” and also “a person who is good and noble”.

That statement impressed me more than the part about being brave. So I thought about something very important. And I remembered what happened to me years ago.

After my marriage of twenty years ended, I was in such a condition. I was within hours trying to get up enough courage to end the pain and misery. When I returned home, someone had sent me a card in the mail which told me how much they would appreciate me as a friend. That wonderful card probably saved my life. That person, without even knowing it, saved a life and became a hero.

The many stories I kept writing in the following years saved the life of a teenage boy. In turn that makes the person who sent me the card a double hero. I suppose that is why I fight so hard to help the children now living in orphanages (孤儿院). Most children come out of these institutions with a very hard and bitter attitude against the world. The gifts we send them let them know that they have not been forgotten. Hopefully, most of them will never hurt anyone because of the kindness shown to them by those of us who cared. If it works, we will also become "heroes".
