Hanging Gardens of Babylon(巴比伦空中花园)

The Hanging Gardens of Babylon were built in the 7^th century BC and are considered one of the Seven Wonders of the Ancient World. The Hanging Gardens of Babylon were amazing not only because of their beauty, but also because of their location.
In the 7^th century BC a king named Nebudchadnezzar II created the gardens as a sign of love for his wife, Amyitis. According to legend, Amyitis, the daughter of the king of the Medes, was homesick. She missed the green hills and valleys of her homeland.
Upon marrying Nebudchadnezzar II, Amyitis moved to the ancient chief city of Babylon. The area was in the Mesopotamian desert, and the climate there was totally different from where she had left. So the new queen was very sad about the flat and the sun-baked desert. To make Amyitis happier and more comfortable the king decided to build her a series of magnificent gardens.
Many think of the gardens as an otherworldly creation that hung in the air somehow. But experts agree that the gardens were actually built on a mountainside, rather than actually “hanging”.
The hanging Gardens of Babylon are famous. Stories of them spread throughout the ancient world, and ancient writers recorded a large number of descriptions of the gardens, but some wonder whether this paradise of the past ever existed. There are no historical records of it except stories. Whatever may happen, even the idea of the Hanging Gardens of Babylon is amazing. They were essentially impossible to create because of the climate, but they were kept in the minds of many as a botanical beauty created in the middle of unattractive desert scenery.
