Once there was a merchant who had fine silks and rug（s a city on the other side of the desert (毛毯) to sell. He wished to send his goods to Abdul the merchant owned a large caravan（商队）of camels, and he employed many men. For many days, Abdul and his men had been preparing for the journey, because of the boundless desert with hot sand and the grass out of sight for miles. It required many camels to carry the merchant's goods, tents, bottles of water, firewood, bags of rice and some tools.
At last the caravan was ready for the journey. The sun shone steadily, making the sand so hot that no one could walk upon it in the daytime. So Abdul and his men traveled all that night. One man was the pilot. He rode ahead because he knew the stars, and he could guide the caravan by them.
They traveled night after night, resting during the heat of the day. Unfortunately, when the caravan started another evening, the pilot led the way as usual, but after a while, weary with many nights of watching, he fell asleep.
All night long the caravan traveled. At daybreak the pilot awoke and looked at the last star fading in the morning light. "Halt（停下）!" he called." The camels must have turned while I slept. We are at the place from which we started yesterday." Even worse, another man shouted, "The man with the camel carrying the rest water and firewood, who is walking at the end of our group, is gone!"
There was no water to drink. There was no firewood to cook the food. The men lay down with despair, "We are lost!"
