Almost everyone has read about the Taj Mahal in India. It is one of the most beautiful buildings in the world. It is said that the Taj Mahal, like the Great Wall in China, is one of the seven wonders. in the world. Over three hundred years ago, Shah Jehan built Taj Mahal as a tomb for his wife. Shah Jehan wanted his wife' s tomb to be perfect. He did not care about time or money. He brought together workmen from all Asia. Altogether, over 20,000 men worked on the building, and it took them over seventeen years to finish it. The building rests on a platform of red sandstone. Four thin white towers rise from the corners of the terrace(平台),a large dome (圆屋顶) rises from the center of the buildings. Around this large dome there are four smaller domes. The building is made of fine white marbles. It has eight sides. There is an open corridor just inside the walls. From the corridor, the visitor looks through marble screen to a center room. The bodies of Shah Jehan and his wife lie in a tomb below this room. A beautiful garden surrounds the Taj Mahal. The green trees make the marble look even whiter. In front of the main entrance to the building there is a long narrow pool. If you look in this pool, you can see all the beautiful look of the Taj Mahal in the reflection from the water. Some people think the Taj Mahal is most beautiful at sunset. Then the marble picks up the color of sunset, and the building and its reflection in the pool shines like jewels. Others like it best at noon when the bright sun makes it clear and clean. Still others think it should be seen by moonlight. On nights when the moon is full, hundreds of people visit the Taj Mahal and spend the night beside the pool. When morning comes and the Taj Mahal tums from silver to gold in the early sunrise, they go away to retum, perhaps, when the moon is full again.
