填空题Ready to Scream? Fear can be fun. Many young people queue up to ride very fast and scary (吓人的) roller coasters, screaming but enjoying themselves. Other people like to read "goose bumps" (鸡皮疙瘩) books or watch horror movies (恐怖电影) at night, scared to death but feeling excited. 1 Fear is an ancient way of surviving. Being scared makes animals (including humans) flee (逃走) from danger and save themselves. It is because of fear that we have lived through millions of years of evolution. 2 What happens in the brain when something frightens you? Nerves (神经) that begin at the eyes and ears lead to a part of the brain called the amygdala (扁桃体). When you suddenly see a snake, for example, the amygdala makes you freeze, perspire (流汗), have a quickened heartbeat, or run very fast. However, seeing the snake also uses another part of the brain, the cortex (皮层). It analyzes the situation, and if it finds that the snake is only made of rubber it tells your heart and the rest of your body to calm down. 3 Back to the first question: Why do some people like to make themselves scared? 4 Kalin said: "To believe we have control over a situation gives us a feeling of power." Scary movies or novels are good practice to prepare young people for the real thing. 5 And there might be some evolutionary advantage to being able to adjust this system that is there to protect people. A. Thrills (恐惧) such as roller coaster rides also go to the brain"s pleasure centre. B. Why do people like being scared? C. One reason is that we can play games with fear, and find ways to reduce the scariness by looking away or thinking of something else. D. Those who lacked a strong fear response (反应) were more likely to be killed, leaving the more timid and careful to pass their genes (基因) onto the next generation. E. Think of the amygdala as the engine and the cortex as the brake. F. Screaming saves ancient people"s life.

单选题{{B}}第二篇{{/B}} Oceanography Oceanography has been defined as "the application of all sciences to the study of the sea. " Before the nineteenth century, scientists with an interest in the sea were few. Certainly Newton considered some theoretical aspects of it in his writings, but he was reluctant to go to sea to farther his work. For most people the sea was remote, and with the exception of early intercontinental (大陆间的 ) travelers or others who earned a living from the sea, there was little reason to ask many questions about it, let alone to ask what lay beneath the surface. The first time that the question-" what is at the bottom of the oceans?" had to be answered with any commercial consequence was when the laying of a telegraph cable from Europe to America was proposed. The engineers had to know the depth profile(起伏形状)of the route to estimate the length of cable that had to be manufactured. It was to Maury of the LIS Navy that the Atlantic Telegraph Company turned, in 1853, for information on this matter. In the 1840s, Maury had been responsible for encouraging voyages during which soundings(测水深) were taken to investigate the depths of the North Atlantic and Pacific Oceans. Later, some of his findings aroused much. popular interest in his book "The Physical Geography of the Sea". The cable was laid, but not until 1866 was the connection made permanent and reliable. At the early attempts, the cable failed and when it was taken out for repairing it was found to be covered with living creatures, a fact which defied contemporary scientific opinion that there was no life in the deeper parts of the sea. Within a few years oceanography was under way. In 1872, Thomson led a scientific expedition (考察), which lasted for four years and brought home thousands of samples from the sea. Their classification and analysis occupied scientists for years and led to a five-volume report, the last volume being published in 1895.

单选题Charlie Chaplin Charlie Chaplin was born on April 16, 1889 in London. His father was an entertainer and although not one of the big names, he was doing very well. His mother Hannah was also an entertainer. While they were by no means rich, the music hall provided the Chaplins with a comfortable living. Unfortunately happy life didn't last long. Father's alcoholism was slowly, but surely destroying his marriage. Finally it ended in divorce. But Hannah was indomitable (不屈不挠的). Without her, Charlie Chaplin would have become just one more child lost in the poverty of Victorian London. Somehow she not only managed to keep Charlie and his brother Sydney clean and warm, clothed and fed, but she conjured (变戏法)little treats for them. She would sit at the window watching the passers-by and guess at their characters from the way they looked and behaved, spinning tales to delight Charlie and Syney. Charlie took in her skills and went on using them all his life. Charlie had always believed, even in the worst time, that he had some special potential inside him. He took his courage and went to see one of the top theatrical agents. With no experience at all,he was being offered the part of Billy, the pageboy (小听差) in a new production of "Sherlock Holmes". "Sherlock Holmes" opened on July 27, 1903 at the enormous "Pavilion Theatre". Charlie seemed to change overnight. It was as if he had found the thing he was meant to do. In 1910, when Kamo set off on its yearly American tour, Charlie was regarded as "one of the best pantomime (哑剧)artists ever seen here. " They had reached Philadelphia when a telegram arrived and he was being offered the chance to replace a star in the Keystone film company. Cinema was born in the same year as Charlie, though people still believed it was a passing fad (一时的狂热，时尚), and would never replace live shows. He was kept hanging about for several weeks and he used the time to watch and learn. He was determined to master this new medium. It offered him the chance of money and success and it would set him free from the unpredictability of live audience. Charlie's first film, released in February 1914, was called "Making a living". Though it didn't satisfy Charlie, the public liked it. After that he made ten films and he learned a lot. The public loved him and distributors were demanding more and more Chaplin films. In an incredibly short time, Charlie had become a very important man in motion picture.
