Where Did All the Ships GoThe Bermuda Triangle (三角区) is one 1 the greatest mysteries of the sea. In this triangular area between Florida, Puerto Rico and Bermuda in Atlantic, ships and airplanes 2 to disappear more often than in 3 parts of the ocean. And they do so 4 leaving any sign of an accident or any dead bodies.It is 5 that Christopher Columbus was the first person to record strange happenings in the area. His compass stopped working, a flame came down from the sky, and a wave 100 to 200-feet-high carried his ship about a mile away.The most famous disappearance in the Bermuda Triangle was the US Naval (海军的) Air Flight 19. 6 December 5, 1945, five bomber planes carrying 14 men 7 on a training mission from the Florida coast. Later that day, all communications with Flight 19 were lost. They just disappeared without a trace.The next morning, 242 planes and 19 ships took part in the largest air-sea search in history. But they found nothing.Some people blame the disappearances 8 supernatural (超自然的) forces. It is suggested the 9 ships and planes were either transported to other times and places, kidnapped (绑架) by aliens (外星人) 10 attacked by sea creatures.There are 11 natural explanations, though. The US Navy says that the Bermuda Triangle is one of two places on earth 12 a magnetic compass (指南针) points towards true north 13 magnetic north. 14 , planes and ships can lose their way if they don"t make adjustments.The area also has changing weather and is known 15 its high waves. Storms can turn up suddenly and destroy a plane or ship. Fast currents could then sweep away any trace of an accident.

Every Dog Has His SayKimiko Fukuda always wondered what her dog was trying to say. Whenever she put on makeup, it would pull at her sleeve. 1 When the dog barks, she glances at a small electronic gadget (装置). The following "human" translation appears on its screen: "Please take me with you." "I realized that"s how he was feeling," says Fukuda.The gadget is called Bowlingual, and it translates dog barks into feelings. People laughed when the Japanese toymaker Takara Company made the world"s first dog-human translation machine in 2002. But 300,000 Japanese dog owners bought it. 2 "Nobody else had thought about it," said Masahiko Kajita, who works for Takara. "We spend so much time training dogs to understand our orders; what would it be like if we could understand dogs"Bowlingual has two parts. 3 The translation is done in the gadget using a database containing every kind of bark.Based on animal behaviour research, these noises are divided into six categories: happiness, sadness, frustration, anger, declaration and desire. 4 In this way, the database scientifically matches a bark to an emotion, which is then translated into one of 200 phrases.When a visitor went to Fukuda"s house recently, the dog barked a loud "bow wow". 5 It was followed by "I"m stronger than you" as the dog growled and sniffed (嗅) at the visitor.The product will be available in US pet stores this summer for about US $120. It can store up to 100 barks, even recording the dog"s emotions when the owner is away.A. A wireless microphone is attached to the dog"s collar, which sends information to the gadget held by the owner.B. Nobody really knows how a dog feels.C. This translated as "Don"t come this way".D. More customers are expected when the English version is launched this summer.E. Now, the Japanese girl thinks she knows.F. Each one of these emotions is then linked to a phrase like "Let"s play", "Look at me", or "Spend more time with me".
Even Intelligent People Can Fail1 The strikin9 thing about the innovators who succeeded in making our modern world is how often they failed. Turn on a light, take a photograph, watch TV, search the Web, jet across the Pacific Ocean, talk on a cellphone (手机). The innovators who left us these things had to find the way to success through a maze (错综复杂) of wrong turns.2 We have just celebrated the 125th anniversary of American innovator Thomas Edison"s success in heating a thin line to white-hot heat for 14 hours in his lab in New Jersey, US. He did that on October 22, 1879, and followed up a month later by keeping a thread of common cardboard alight (点亮着的) in an airless space for 45 hours. Three years later he went on to light up half a square mile of downtown Manhattan, even though only one of the six power plants in his design worked when he turned it on, on September 4, 1882.3 "Many of life"s failures," the supreme innovator said, "are people who did not realize how close they were to success when they gave up." Before that magical moment in October 1879, Edison had worked out no fewer than 3,000 theories about electric light, but in only two cases did his experiments work.4 No one likes failure, but the smart innovators learn from it. Mark Gumz, the head of the camera maker Olympus America Inc, attributes some of the company"s successes in technology to understanding failure. His popular phrase is. "You only fail when you quit."5 Over two centuries, the most common quality of the innovators has been persistence. That is another way of saying they had the emotional ability to keep up what they were doing. Walt Disney, the founder of Disneyland, was so broke after a succession of financial failures that he was left shoeless in his office because he could not afford the US $1.50 to get his shoes from the repair shop. Pioneering car maker Henry Ford failed with one company and was forced out of another before he developed the Model T car.6 Failure is harder to bear in today"s open, accelerated world. Hardly any innovation works the first time. But an impatient society and the media want instant success. When American music and movie master David Geffen had a difficult time, a critic said nastily that the only difference between Geffen Records (Geffen"s company) and the Titanic (the ship that went down) was that the Titanic had better music. Actually, it wasn"t. After four years of losses, Geffen had so many hits (成功的作品) he could afford a ship as big as the Titanic all to himself. The media demand that ______.

请详细阅读有关数据架构方面的描述，根据要求回答下面问题。[说明]某软件公司欲开发一个基于Web 2.0的大型社交网络系统。就该系统的数据架构而言，李工决定采用公司熟悉的数据架构，使用通用的商用关系型数据库，系统内部数据采用中央集中方式存储。该系统投入使用后，初期用户数量少，系统运行平稳。6个月后，用户数出现了爆炸式增长，系统暴露出诸多问题，集中表现在：(1)用户执行读写操作时，响应时间均变得很慢。(2)随着系统功能的扩充，原有数据格式发生变化，又出现新的数据格式，维护困难。(3)数据容量很快超过系统原有的设计上限，数据库扩容困难。(4)软件系统不断出现宕机，整个系统可用性较差。经过多次会议讨论，公司的王工建议采用NoSQL数据库来替代关系数据库，以解决上述问题。但李工指出NoSQL数据库出现时间不长，在使用上可能存在风险。公司技术人员对NoSQL数据库产品进行了认真测试，最终决定采用NoSQL数据库来替代现有的数据库系统。 分别解释产生问题(1)～(4)的原因。
