1._____
     New Orleans, the city of Louisiana, is one of the most colorful and interesting places in North America.
It is well known for its multicultural cuisine (菜肴) and its colonial architecture and is considered by most
experts to be the birthplace of jazz, the one music style that the USA can lay claim to inventing.
2._____
     The city was founded in 1718, at a time when France owned that part of North America. Part of its
diversity results from the fact that it was subjected to many different influences. France sold Louisiana to
Spain in1763, got it back 40 years later, and almost immediately sold the territory to the USA.
3._____
     As the city prospered (繁荣), it became a magnet (磁铁) for all kinds of immigrants from Europe and
other parts of the USA, and was also the first choice destination of breed black slaves. The rich cultural mix
led to a relaxed attitude to life and an appreciation of good food, wine, music and dancing. There were
frequent festivals.
4._____
     By the end of the 1700s, people of African descent (祖先) made up more than half the city's population.
Many more arrived via the Caribbean and brought with them West Indian cultural traditions. By the mid-18th
century, black New Orleans people were gathering socially on Sundays at a special market outside the city,
where they were able to remember and practice their traditional African dance and drumming music. The
roots of jazz can be traced to these events.
5._____
     Native American musicians then combined their music with the African traditions and bands playing a
mixture of styles began to perform in street festivals. Europeans came to listen and contribute and the roots
of jazz were established. Louis Armstrong, the most famous jazz musician of all time, was influenced by these
rich musical mixtures when he heard them in the early years of the 20th century.
