单选题
If there is one thing certain to get Brazilians on their feet, it is the Rio Carnival (狂欢节). Held in Rio de Janeiro, the country's biggest city, the carnival began on February 20 when the mayor gave key of the city to Rei Momo-the Lord of Misrule (无序之皇)
On his orders, each year people turn the city into a paradise of dance and music. The following six days are so fun of parades, street dancing, fantastic clothes and partying (聚会) that many people forget about eating and sleeping.
"It was the passion of the carnival that attracted me to Brazil and made me settle down in Rio. " said Bob Nadkarni, a British man who has lived in the city for several years. For many Brazilians, the centerpiece of the carnival is samba (桑巴舞) , a typical Brazilian dance. Every year, tens of thousands of visitors and locals show off their passion and energy in the streets, following the beat (节拍) of the Latin music.
The climax to this street party is the float(彩车) parade, in which floats decorated with tons of fresh flowers by various samba schools and local communities move through the city. On the top of each float stands the candidate for the Drum Queen, who is chosen at the end of the party.
While most people are free to enjoy the celebrations. Rio's police officers have to keep a clear head. Following the murder of three officers in a gunfight early last week, the Brazilian Government has tightened security in Rio. The street fighting, robbery and sex crimes that accompany the carnival are very difficult to police.
Carnivals began in ancient Rome as a celebration at which people fed wild wolves, in honor of the city's founder who was said to have been raised by a she-wolf. Brazil gave new life to this tradition and so despite the troubles, the carnival will remain a symbol of the country's culture.
