14．
Dubai is a city of big business，expensive hotels，skyscrapers（摩天樓），and shopping malls．In the early 20th century，Dubai was a successful trading port．People from the world stopped in Dubai to do business．But it was still a small city，and most people lived as fishermen and businessmen．Then in 1966，oil was discovered．This brought a lot of money into the area，and soon Dubai began to change．
Today Dubai is one of the world's most important business centers．In fact，each year the city gets its money mainly from business，not oil．
Recently Dubai has attracted more and more visitors from abroad．They come to relax on its beaches，and every year，millions visit just to go shopping!
Dubai is also one of the world's fastest growing cities．Many tall buildings are built in months．The city also has many man-made islands．One of these，the Palm Jumeirah，is like a palm tree （棕桐樹） and is very beautiful．
The city is still an amazing mix（混合體） of people from different countries．The people from 150countries live and work in Dubai，and foreigners now outnumber Dubai natives（本地人） by eight to one!
Many people welcome the city's growth．But an increasing number of Dubai natives worry about the speed of change．As a Dubai native says，"We must always remember where we came from． Our kids must know we worked very，very hard to get where we are now，and there's a lot more work to do．"
