Light travels at a speed which is about a million times faster than the speed of sound. You can get some idea of this difference by watching the start of a race. If you stand some distance(距离) away from the starter, you can see smoke from his gun before the sound reaches your ears.

This great speed of light produces some strange facts. Sunlight(太阳光) takes about 8 minutes to reach us. If you look at the light of the moon tonight, remember that the light rays left the moon 1.3 seconds before they reached you. The nearest star is so far away that the light that you can see from it tonight started to travel towards you four years ago at a speed of nearly 2 million km. per minute. In some cases, the light from one of tonight’s stars had started on its journey to you before you were born.

Thus, if we want to be honest, we can’t say, “The stars are shining tonight.” We have to say instead, “The stars look pretty. They were shining four years ago, but their light has only just reached the earth.”

I knocked into a man as he passed by．"Oh，excuse me ，please，" I said．He replied，"Please excuse me too．I didn't notice where I was going．"

Later that day，while I was cooking，my son stood behind me quietly When I turned around，I nearly knocked him down．"Move oat of the way，" I shouted．He walked away with his little heart broken．

That night while I was lying in bed，a voice crone to me，"When saying to that man，you used good manners．But to the child you love，you seemed to act in a bad way．Look at the kitchen floor，and you'll find some flowers there by the door．Those are the flowers your son brought for you．He picked them himself He stood quietly to give you a surprise，and you never saw the tears in his eyes．"

By this time，tears began to run down my face．I took the flowers and went to his bed．I asked him，"Are these the flowers you picked for me?"

He smiled．"I found them by the tree．I picked them because they're pretty like you．I know you'd like them"

"Son，I'm sorry for the way I acted today．I shouldn't have shouted at you that way．"

"Oh，Morn，that's OK．I love you anyway．"

"Son，I tore you，too．And I do like the flowers．"

If we die tomorrow，the family we leave behind will feel sad for the rest of their life．Why don't we spend more time with our family，and why aren't we nice to them?
