　　手机泄露了你的秘密

　　你的手机承载着你的秘密。一项新研究发现，手机里除了存有你输入的名字和号码外，还留有你的微量DNA(脱氧核糖核酸)。

　　DNA(脱氧核糖核酸)是细胞里的基因物质，如同指纹，你的DNA是独一无二的——除非你是同卵双生双胞胎之一。今天科学家一般可以在犯罪现场遗留的血液、唾液、毛发中分析出DNA。分析结果经常能帮侦探识别罪犯和受害人。你的手机能透露出比你想象的要多得多的信息。

　　安大略省汉密尔顿mcmaster大学的科学家meghan J.mcFadden听说了在一起犯罪中嫌疑人的血流到了手机上，后来还丢掉了手机。这让她想到手机上是否留下了犯罪嫌疑人的DNA——即使血不流到手机上。于是，她和纽约城市大学的同事margaret wallace分析了10个志愿者的翻盖手机。他们使用药签从手机的两个部位，即使用者把持的外壳，靠近使用者耳部的听筒部分，采集到了肉眼看不到的手机使用者的微量DNA。

　　科学家们用一种主要由酒精构成的溶液擦洗手机。擦洗的目的是去除所有易被察觉的DNA。之后，机主拿回手机使用一周。接着，研究者又把手机收回来，重复了用药签采取每部手机遗留微量DNA的步骤。

　　科学家们在每部手机的听筒部分都发现了DNA，从手机外壳的取样更为明显，但手机外壳的取样中还发现了那些曾摆弄过该手机的其他人的DNA.

　　令人称奇的是，DNA甚至出现在擦洗手机之后的药签中，这意味着清洗不会完全去掉罪犯手机上的微量DNA证据。因此，现在手机可以作为协助犯罪现场调查得出定论的线索之一。

　　第四篇 Sharks Perform a Service for Earth's waters (A)

　　It is hard to get people to think of sharks as anything but a deadly enemy. They are thought to 1 people frequently. But these fish perform a 2 service for earth's waters and for human beings. Yet business and sport fishing are threatening their 3 Some sharks are at risk of disappearing from 4 .

　　warm weather may influence both fish and shark activity. many fish swim near coastal areas 5 their warm waters. Experts say sharks may follow the fish into the same areas, 6 people also swim. In fact, most sharks do not purposely charge at or bite humans. They are thought to mistake a person 7 a sea animal, such as a seal or sea lion. That is why people should not swim in the ocean when the sun goes down ores up. Those are the 8 when sharks are looking for food. Experts also say that bright colors and shiny jewelry may cause sharks to attack.

　　A shark has an extremely good sense of smell. It can find small amounts of substances in water, such as blood, body liquids and 9 produced by animals. These powerful 10 help sharks find their food. Sharks eat fish, any 11 sharks, and plants that live in the ocean.

　　medical researchers want to learn more about the shark's body defense and immune 12 against disease. Researchers know that sharks 13 quickly from injuries. They study the shark in hopes of finding a way to fight human disease.

　　Sharks are important for the world's 14 . They eat injured and diseased fish. Their hunting activities mean that the numbers of other fish in ocean waters do not be too 15 This protects the plants and other forms of life that exist in the oceans.

　　鲨鱼有益于地球水系

　　要让人们相信鲨鱼不是人类的死敌不是一件容易的事。人们认为鲨鱼经常袭击人类。但鲨鱼在为地球水系和人类作着有价值的贡献。商业和捕鱼运动仍在威胁着他们的生存，有些鲨鱼面临着从地球上消失的危险。

　　温暖的气候影响着鱼类和鲨鱼的活动。由于水温变暖，很多鱼类游到海边。专家认为鲨鱼跟随其它鱼类，也来到人类游泳的区域。实际上鲨鱼并非故意袭击人类。人们认为，由于鲨鱼将人错认为是海狮等海洋动物，在饥饿时才袭击人类。日出和日落时，正是鲨鱼饥肠辘辘的时候，人们不应该出海游泳。专家还提到鲜艳的色彩和闪光的珠宝也会诱使鲨鱼袭击。

　　鲨鱼的嗅觉特别灵敏，能嗅到海水中存在的极为微量的气味，比如血液、体液和动物散发的化学物质。灵敏的嗅觉有助于鲨鱼找到食物。鲨鱼以鱼、其他鲨鱼和海洋植物为生。

　　医学研究人员想要更多了解的是鲨鱼的身体抗病免疫系统。研究人员发现鲨鱼受伤会很快康复，他们希望通过研究鲨鱼，找到一种人类抗病的方法。

　　鲨鱼有益于海洋。它们吃受伤的和生病的鱼。他们的捕猎活动使其它海洋鱼类的数目不会过多，这就保护了海洋中的植物和其它生灵。

　　captain cook Arrow Legend

　　It was a great legend while it lasted, but DNA testing has 1 finally ended a two-century-old story of the Hawaiian arrow carved from the bone of British explorer captain James cook 2 who died in the Sandwich Islands in 1779.

　　“There is 3 no cook in the Australian museum,” museum collection manager Jude Philip said not long ago in announcing the DNA evidence that the arrow was not made of cook's bone. But that will not stop the museum from continuing to display the arrow in its 4 exhibition , “uncovered: Treasures of the Australian museum,” which 5 does include a feather cape presented to cook by Hawaiian King Kalani’opu’u in 1778.

　　cook was one of Britain’s great explorers and is credited with 6 discovering the “great South Land,” 7 now Australia, in 1770. He was clubbed to death in the Sandwich Islands, now Hawaii.

　　The legend of cook’s arrow began in 1824 8 when Hawaiian King Kamehameha on his deathbed gave the arrow to william Adams, a London surgeon and relative of cook’s wife, saying it was made of cook’s bone after the fatal 9 fight with islanders.

　　In the 1890s the arrow was given to the Australian museum and the legend continued 10 until it came face-to-face with science.

　　DNA testing by laboratories in Australia and New zealand revealed the arrow was not made of cook’s bone but was more 11 likely made of animal bone, said Phi.

　　However, cook’s fans 12 refuse to give up hope that one cook legend will prove true and that part of his remains will still be uncovered, as they say there is evidence not all of cook’s body was 13 buried at sea in 1779. “on this occasion technology has won,” said cliff Thornton, president of the captain cook Society, in a 14 statement from Britain. “But I am 15 sure that one of these days...one of the cook legends will prove to be true and it will happen one day.”

　　库克船长弓箭的传说 (c)

　　这本是个绝妙的传说，但DNA测试最终结束了这个长达两个世纪之久的古老故事。传说是关于一支据说是用1779年在桑伟奇群岛死去的英国探险家船长詹姆士库克的遗骨刻成的夏威夷弓箭。

　　在不久前DNA 证据宣布该弓箭并非来自于库克船长的遗骨时，奥大利亚博物馆收藏经理尤大书•菲利普说：“澳大利亚博物馆里并没有库克的遗骨。”但这并不能停止博物馆在展览会上展出弓箭。“考古发现：澳大利亚博物馆的宝藏”展览中的确还展示了一个在1778年夏威夷国王卡兰尼欧普送给库克的一个羽毛斗篷。

　　库克是英国最伟大探险家之一，他在1770年发现了“南大陆”，也就是现在的澳大利亚。此后在桑伟奇群岛被棒击致死。

　　库克弓箭传说始于1824年，当时夏威夷国王卡莫哈莫哈在弥留之际将弓箭赐给了库克妻子的亲戚，一名伦敦外科医生威廉正当斯，并告诉他弓箭是在那次致命殴打后用库克的遗骨做成的。

　　在19世纪90年代，弓箭被交给澳大理亚博物馆。这个传说直到与科学直接接触才停止。据菲利普说，澳大利亚和新西兰的试验室的DNA测试证实弓箭并非取材于库克的遗骨，而更可能来自动物的骨头。

　　但是，库克迷们却不肯放弃希望。他们期待库克传说之一将会被证明是正确，并且他人部分遗骨还会被发现。正如他们所说，有证据表明库克的遗骨并不是在1779年全都葬身大海了。库克船长协会的会长克利夫托马森在一个来自英国的声明中说：“在这个问题上，科技取得了胜利。我坚信某一天库克传说之一将会被证明是真的。”
