　　The Great Wall of China, the longest wall in the world, runs across north China like a huge dragon. It winds its way from west to east, across deserts over mountains, through valleys, till at last it reaches the sea. It in one of the wonders of the world. And it was one of the few man-made objects on earth that could be seen by the astronauts who landed on the moon.

　　The Great Wall has a history of over twenty centuries. The first part of it was built during the Spring and Autumn Period (770 B. C～476 B. C.). During the Warring States Period (475 B. C.～221 B.C.), more walls were put up to defend the borders of the different kingdoms. In 221 B. C. the kingdom of Qin united the different parts of China into one empire. To keep the enemy out of his empire, Emperor Qin Shihuang had all the walls joined up. Thus the Great Wall came into being. Since then, it has often been added to, rebuilt and repaired, especially during the Ming Dynasty (1368 ～1644).

　　The Great Wall, which is called in Chinese “The Ten-thou-sand-li Great Wall”, is actually more than 6000 kilometers long, 6～7 meters high and 4～5 meters wide. In most places it is wide enough for five horses or ten men to walk side by side along the top. It has great gateways which connect the main roads of north China.

　　Every few hundred meters along the wall there are watch towers, where soldiers used to keep watch. When the enemy came, fires were lit and at the same time guns were fired to warn soldiers at other towers, one column of smoke with one gunshot meant an enemy troop of about 100, two columns with two shots meant 500. In this way, a warning message could be sent 500 kilometers within a few hours.

　　It was very difficult to build and rebuilt such a great wall over wild and distant country without any modern machines, all the work had to be done by hand. Many people were forced to work in the wall far away from their homes. They lifted earth in baskets, passed bricks from hand to hand and dragged heavy stones with ropes over their shoulders. Their living conditions were terrible. Thousands of men died and were buried under the wall they built. The Great Wall was made not only of stone and earth, but of the flesh and blood of millions of men.

　　After the Great Wall was rebuilt hundreds of years ago, no more work was done on it until the People's Republic of China was founded. After that, parts of the wall were repaired. On both sides of it new cities appeared, trees were planted, and deserts became grasslands. The old Great Wall took on a new look.

　　Today the Great Wall has become a place of interest not only to the Chinese people, but also to the people from all over the world.

     We lived in a very quiet neighborhood. One evening I heard a loud crash in the street. Earlier that
evening my wife had asked me to go to the store to get some soft drinks. It seemed like this would be a
good time to let my teenage daughter Holly practice her driving, so I sent her to the store in my truck. At
dinner my son talked about how much he liked my truck. I enjoyed having it, but I said: "Guy, my heart is
not set on that truck. I like it but it is just metal and won't last forever. Never set your heart on anything that
won't last. "After hearing the loud noise, the whole family ran outside. My son shouted: "Dad! Dad, Holly
crashed your truck. "
     My heart sank and my mind was flooded with conflicting thoughts. Was anyone hurt? Who else was
involved? As I ran to the door, I heard a voice in my heart say: "Here is a chance to show Holly what you
really love. She'll never forget it. "
     The accident had occurred in my own driveway. Holly had crashed my truck into our other vehicle, the
family van. In her inexperience, she had confused the brakes and the gas pedal (油门]). Holly was unhurt
physically but when I reached her, she was crying and saying: "Oh, Dad, I'm sorry. I know how much you
love this truck. "I held her in my arms as she cried.
     Later that week a friend stopped by and asked what had happened to my truck. I told her the whole
story. Her eyes moistened (润湿) and she said: "That happened to me when I was a girl. I borrowed my
dad's car and ran into a log that had fallen across the road. I ruined the car. When I got home my Dad
knocked me to the ground and began to kick me. "
     Over 40 years later, she still felt the pain of the night. It was a deep wound on her soul.
     I remember how sad Holly was on the night she crashed our truck, and how I comforted her. One day,
when Holly thinks back on her life, I want her to know that I love her a thou- sand times more than any
piece of property.
     I repaired the van, but the dent (凹陷) in my truck is still there today. Every day it re- minds me of
what really matters in my life.
