单选题{{B}}第二篇{{/B}} {{B}} Dancing in the Streets{{/B}} 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 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), 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 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.

单选题Three Ways to Become More Creative Most people believe they don't have much imagination. They are wrong. Everyone has imagination, but most of us, once we become adults, forget how to access it. Creativity isn't always connected with great works of art or ideas. People at work and in their free time routinely think of creative ways to solve problems. Maybe you have a goal to achieve, a tricky question to answer or you just want to expand your mind! Here are three techniques to help you. This technique involves taking unrelated ideas and trying to find links between them. First, think about the problem you have to solve or the job you need to do. Then find an image, word, idea or object, for example, a candle. Write down all the ideas/words associated with candles: light, fire, matches, wax, night, silence, etc. Think of as many as you can. The next stage is to relate the ideas to the job you have to do. So imagine you want to buy a friend an original present; you could buy him tickets to a match or take him out for the night. Imagine that normal limitations don't exist. You have as much time/space/money, etc. as you want. Think about your goal and the new possibilities. If, for example, your goal is to learn to ski(滑雪),you can now practice skiing every day of your life(because you have the time and the money). Now adapt this to reality. Maybe you can practice skiing every day in December, or every Monday in January. Look at the situation from a different point of view. Good negotiators(谈判者)use this technique in business, and so do writers. Fiction writers often imagine they are the characters in their books. They ask questions: what does this character want? Why can't she get it? What changes must she make to get what she wants? What does she dream about? If your goal involves other people, put yourself "in their shoes". The best fishermen think like fish!

单选题Learning Disorder-Dyslexia As many as 20% of all children in the United States suffer from some form of the learning disorder called dyslexia. Experts on dyslexia say that the problem is not a disease. They say that persons with dyslexia use information in a different way. One of the world's great thinkers and scientists Albert Einstein was dyslexic. Einstein said that he never thought in words the way that most people do. He said that he thought in pictures instead. The American inventor Thomas Edison was also dyslexic. Dyslexia first was recognized in Europe and the United States more than 80 years ago. Many years passed before doctors discovered that persons With the disorder were not mentally slow or disabled. The doctors found that the brains of persons with dyslexia are different. In most people, the left side of the brain—the part that controls language—is larger than the right side. In persons with dyslexia, the right side of the brain is bigger. Doctors are not sure what causes this difference. However, research has shown that dyslexia is more common in males than in females , and it is found more often in persons who are left-handed. No one knows the cause of dyslexia, but some scientists believe that it may result from chemical changes in a baby's body long before it is born. They are trying to find ways to teach persons with dyslexia Dyslexic persons think differently and need special kinds of teaching help. After they have solved their problems with language, they often show themselves to be especially intelligent or creative.
