Dancing in the Streets If there is one thing certain to get Brazilians on their feet, it is ,the Rio Carnival （狂欢）. 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 full 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 centrepiece of the carnival is samba （桑巴舞）, atypical 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 honour 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. 第 36 题 According to the passage, during the Carnival people in Rio did all of the following EXCEPTA．dancing in thestreets.B．putting on colorful clothes.C．eating a lot of food.D．holding exciting parades.

单项选择题
Technolog Transfer in Germany When it comes to translating basic research into industrial success, few nations can match Germany.Since the 1940s, the nation's vast industrial base has been fed with a constant stream of new ideas and expertise from science. And though German prosperity （繁荣） has faltered （衰退） over the past decade because of the huge cost of unifying east and west as well as the global economic decline, it still has an enviable record for turning ideas into profit.Much of the reason for that success is the Fraunhofer Society, a network of research institutes that, exists solely to solve industrial problems and create sought-alter technologies. But today the Fraunhofer institutes have competition. Universities are taking an ever larger role in technology transfer, and technology parks are springing up all over. These efforts are being complemented by the federal programmes for pumping money into start-up companies.Such a strategy may sound like a recipe for economic success, but it is not without its critics.These people worry that favouring applied research will mean neglecting basic,science, eventually starving industry of fresh ideas. If every scientist starts thinking like an entrepreneur（企业家）, the argument goes, then the traditional principles of .university research being curiosity-driven, free and widely available will suffer. Others claim that many of the programmes to promote technology transfer are a waste of money because half the small businesses that are promoted are bound to go bankrupt within a few years.While this debate continues, new ideas flow at a steady rate from Germany's research networks, which bear famous names such as Helmholtz, Max Planck and Leibniz. Yet it is the fourth network, the Fraunhofer Society, that plays the greatest role in technology transfer.Founded in 1949, the Fraunhofer Society is now Europe's largest organisation for applied technology, and has 59 institutes employing 12,000 people. It continues to grow.Last year, it swallowed up the Heinrich Hertz Institute for Communication Technology in Berlin. Today, there are even Fraunhofers in the US and Asia. 第 41 题 What factor can be attributed to German prosperity.A．Technology transfer.B．Good management.C．Hard work.D．Fierce competition.
