The U.S. subsidiary of Baidu Inc., a Chinese web services company, has been issued a permit to test self-drive vehicles in California.中国互联网公司百度的美国分公司已经获得了许可,将在加州测试百度研发的无人驾驶汽车。The testing permit, from the California Department of Motor Vehicles (DMV) in the first week of month, would allow Baidu USA to test its autonomous driving technologies in the Golden State.在九月的第一周,加州机动汽车部门向百度发布了这一测试许可,允许百度美国分公司在加州测试自己的自动驾驶技术。Headquartered in Beijing, China, Baidu announced the formation of an autonomous driving team in the ed States, as part of Baidu Autonomous Driving that operates in Chinese cities of Beijing, Shanghai and Shenzhen.总部设在北京的百度公司宣布了美国自自动驾驶研发小组正式成立,该小组是百度在北京、上海、深圳等城市运营的自动驾驶团队的一部分。Following 14 other companies, including German automakers Mercedes Benz and BMW and U.S. automaker Ford, that have obtained the permit to operate self-drive vehicles on public roads in California, Baidu said it would test its vehicles ;very soon.;之前,包括德国汽车制造商奔驰和宝马,以及美国汽车制造商福特在内的14家公司都已获准在加州公共道路上测试无人驾驶汽车,紧随其后的百度公司表示,他们将在“近期”对自己研发的汽车进行测试。;Baidu has aly built a strong team in Silicon Valley to develop autonomous driving technologies, and being able to do road tests will greatly accelerate our progress,; Jin Wang, senior vice president of Baidu and general manager of Baidu#39;s Autonomous Driving , was ed as saying in a web posting earlier in the month.本月上旬,一家网站援引百度高级副总裁、百度自动驾驶团队总经理王劲的话称:“百度已经在硅谷建立了一强大的团队来研发自动驾驶技术,而能够进行路面测试将会大大加速我们的研发进展。” /201609/468159Dinosaurs had feathered, chestnut brown tails with a pale underside, a newly found specimen reveals.新近发现的标本表明,恐龙有覆着羽毛的栗褐色尾巴,且其尾巴底面是浅色的。The tip of the tail was found in an ancient blob of amber tree resin.恐龙尾巴的末端是在一块年代久远的琥珀树脂中发现的。The amber was discovered by Dr Lida Xing from the China University of Geosciences at an amber market in Myanmar in 2015.2015年,中国地质大学的邢立达士在缅甸的一个琥珀市场上发现了这块琥珀。It was initially thought to be plant remains and was destined to become a piece of jewellery until Xing rescued it.最初,这块琥珀被当成一块植物化石,直到邢教授“解救”了它,才摆脱被制作成一件珠宝的命运。The tail belonged to a small, flightless dinosaur that lived in the mid-Cretaceous period around 99 million years ago.这条尾巴属于9900万年前生活在白垩纪中期的一只不会飞的小恐龙。And the rare find sheds light on the evolution of feathers from dinosaurs to modern birds, which cannot be gleaned from normal fossil remains.这个罕见的发现说明了,从恐龙到现代鸟类,羽毛在其身上的演化,而从普通化石中则无法得出这样的结论。The incredible discovery reveals the feathered tail of a non-avian theropod that perished approximately 99 million years ago.这项惊人的发现展示了一只非鸟类的兽脚亚目恐龙覆着羽毛的尾巴,而这只恐龙在9900万年前就灭亡了。Dr Ryan McKellar, Curator of Invertebrate Palaeontology at the Royal Saskatchewan Museum in Canada, said: #39;The new material preserves a tail consisting of eight vertebrae from a juvenile. These are surrounded by feathers.’加拿大萨斯喀彻温省皇家物馆馆长、无脊椎动物古生物学士赖安·麦凯勒表示,“保存尾巴的新材料中有一只幼年恐龙的8节椎骨。且这些椎骨被羽毛所包围。”#39;We can be sure of the source because the vertebrae are not fused into a rod or pygostyle as in modern birds and their closest relatives.’“我们可以相信这种信息来源,因为这些椎骨没有像现代鸟类及其亲缘动物那样融合成一根或一节尾综骨。”#39;Instead, the tail is long and flexible, with keels of feathers running down each side.#39;“而且,这条尾巴又长又柔韧,且顺着尾巴的每一面,羽毛的骨架逐渐减少。”Dr McKellar added that the feathers are definitely those of a dinosaur and not a prehistoric bird.麦凯勒士补充道,这些羽毛一定源自一只恐龙而不是一只史前鸟类。#39;Amber pieces preserve tiny snapshots of ancient ecosystems, but they record microscopic details, three-dimensional arrangements, and tissues that are difficult to study in other settings,#39; Dr McKellar said.麦凯勒士指出,“这块琥珀保存了古代生态系统的简况,但它们也记录了其微小细节和立体构造,以及很难在其他背景下研究到的动物组织。”#39;This is a new source of information that is worth researching with intensity and protecting as a fossil resource.#39;“这是一种新的信息来源,值得进行大量的研究,也应将其作为一种化石资源保护起来。”He hopes future finds from the region #39;will reshape our understanding of plumage and soft tissues in dinosaurs and other vertebrates.#39;他希望,未来在这个领域里的发现“将改变我们对鸟类羽毛以及恐龙和其他脊椎动物软组织的理解。” /201612/483038“绝望主妇”伊娃:用法语立下婚誓The endless details were numbing, but Eva Longoria says she kept herself cool at her wedding to Tony Parker last week."My stylist, Robert Verdi, and everybody around me was like, `You're so calm,'" Longoria tells OK! magazine in its latest issue, on newsstands Friday. "I actually don't stress about anything."The 32-year-old "Desperate Housewives" actress and the 25-year-old NBA star wed in a civil ceremony in Paris last Friday. The following day, they exchanged vows in a church across from the Louvre Museum and held an exclusive reception at a storied French chateau."Every girl dreams of having a beautiful, romantic wedding," says Longoria. "It was amazing to see it unfold after months of planning. We really wanted to create an experience for our guests. It was about them having fun."That list included fellow "Housewives" Teri Hatcher and Felicity Huffman and singer Sheryl Crow.Parker, who was born in Belgium and raised in France, notes that Longoria chose the wedding destination."I didn't want to do it in Paris because we'd end up inviting more people than I wanted!" says Parker, eliciting laughs from Longoria.Longoria also giggled during the wedding ceremony as she attempted to say her vows in French."She decided I would do the vows in English; hers would be in French," Parker explains. "There were some tough words. I'm very proud of her." 婚礼筹备中没完没了的琐事几乎能把人弄麻木,而伊娃·朗格莉娅称,在上周她和帕克的婚礼上,她一直保持着镇静和从容。朗格莉娅在接受将于本周五出版的最新一期OK!杂志的采访时说:“我的造型师罗伯特·弗迪和身边的所有人都说,‘你好有定力啊!’其实我对任何事都不会看得太重。”上周五,这位32岁的“绝望主妇”和25岁的NBA球星在巴黎登记结婚。第二天,两人在卢浮宫对面的一个教堂交换婚誓,并在当地的一个古堡举行了一场盛大的婚宴。朗格莉娅说:“每个女孩都梦想能有一个美好、浪漫的婚礼。经过几个月的筹备,我的这个梦想终于实现了,真是美妙极了!我们很想让来宾们能有一番不一样的体验。主要是想让他们开心!”参加婚礼的来宾包括与朗格莉娅共同出演《绝望主妇》的特里·海切尔和费丽西提·胡夫曼两位“主妇”和歌手谢丽尔·克劳。生在比利时、长在法国的帕克说,婚礼地点是朗格莉娅选的。帕克说:“我不想在巴黎办,因为这样邀请的人会太多。”帕克的话引得朗格莉娅直发笑。朗格莉娅在婚礼上尝试用法语说她的婚誓时也忍不住笑了起来。帕克说:“她决定让我用英文说婚誓,她用法语说。有些词挺难说的,我十分为她骄傲。” /200803/31401

Brilliant technologies transform the magical into the banal. 卓越的科技会把神奇的东西变得平淡无奇。An idea that seems outlandish to one generation becomes commonplace to the next. 曾经在一代人看来稀奇古怪的想法对于下一代人却变得稀松平常。So it has been with electricity, space flight and the internet. 电力、太空航行以及互联网都是如此。So it is likely to prove with driverless cars.因此无人驾驶汽车可能也会如此。The past few weeks have seen a flurry of announcements. 近几周这个领域接连传出许多消息。Singapore has launched the world’s first public trial of a robo-taxi service. 新加坡展开了全球首项无人驾驶出租车的公开测试。Uber and Volvo announced that they would pioneer an autonomous taxi fleet in Pittsburgh within weeks. 优步(Uber)和沃尔沃(Volvo)宣布,未来几周内,它们将率先在匹兹堡推出一自动驾驶出租车车队。Ford said it would build its first mass-market driverless car by 2021.福特(Ford)表示,将在2021年前制造其首款面向大众市场的无人驾驶汽车。To their backers, autonomous cars cannot arrive quickly enough. 对于持者而言,自动驾驶汽车越快上路越好。Conventional cars are inefficient, dangerous and dirty. 传统汽车低效、危险且肮脏。They sit idle for 95 per cent of their lives, clogging up city streets and car parks. 它们有95%的时间在闲置,堵塞着城市街道和停车场。When moving, they smash into each other, killing 3,500 people every day around the world. 在行驶中,它们会互相碰撞,全球每天有3500人死于交通事故。Ninety per cent of accidents are caused by human error. 其中90%的事故是人为失误造成的。Cars pollute the environment, accounting for 45 per cent of oil burnt.汽车污染环境,占石油消耗总量的45%。The widesp adoption of fully autonomous and, still better, electric cars could therefore be a massive boon to mankind. 因此完全自动化且质量更好的电动汽车得到广泛应用可能是人类的一大幸事。It could lead to a far more efficient use of resources, save many lives and reduce congestion and pollution. 这可能会带来资源的更有效利用、挽救很多生命并减少拥堵和污染。Futurologists envisage small fleets of shareable, connected cars constantly whizzing around our cities picking up passengers on demand. 按照未来学家的构想,一些由可分享的联网汽车组成的小型车队将时刻不停地绕着我们的城市飞驰,按照需求搭载乘客。McKinsey forecasts that 15 per cent of new cars could be fully autonomous by 2030.麦肯锡(McKinsey)预测,到2030年,15%的新车可能实现完全自动驾驶。But two obstacles block their widesp adoption. 但有两个障碍因素阻碍着自动驾驶汽车的普及。The first remains technological. 第一个仍然是技术上的。For all the astonishing advances made in recent years, it is phenomenally difficult to replicate humans as sensory beings.尽管最近几年这方面技术取得了惊人的进步,但要模仿人类打造具有感觉能力的自动驾驶系统是极其困难的。How does a car distinguish between a plastic bag blowing across a road and a runaway dog? How does a car nudge its way through a throng of people outside a football stadium?汽车如何区分一个被风吹过马路的塑料袋和一条奔跑的?汽车如何穿过足球场外拥挤的人群?Engineers argue that the genius of self-driving cars is their connectedness. 工程师辩称,自动驾驶汽车的优势在于联网。When human drivers make a mistake the individual learns from it, says one Silicon Valley pioneer. When a self-driving car makes a mistake then every other car will learn from a mistake once an engineer has fixed it. 当人类驾驶员犯错时,这个人会从中吸取教训,一位硅谷先驱表示,当一辆自动驾驶汽车犯错时,一旦工程师修复了这个问题,其他所有汽车都会相应改进。It is just a matter of time before our technology surpasses human capacity.科技超越人类能力只是早晚的事。But sceptics compare autonomous car technology with Zeno’s dichotomy paradox: every leap will take us halfway to our destination without ever reaching it.但怀疑者将自动驾驶技术比作芝诺(Zeno)的二分法悖论:每一步跳跃都是向着目的地走出剩余路程的二分之一,但永远不可能到达终点。No matter how hard the technology proves, it may be the easier part of the puzzle. 不管事实明要攻克技术有多难,它也可能是这个难题中较为容易的部分。A stiffer challenge remains the human. 更为严峻的挑战仍然是人类。Even when manufacturers and software engineers develop fully autonomous cars in which they have total trust, it will still take many years, if not decades, for them to be freely embraced by governments and consumers.即便制造商和软件工程师开发出他们自己完全信任的全自动驾驶汽车,也需要花费多年、甚至几十年时间才能得到政府和消费者的安心接纳。First, there is the instinctive human resistance to handing over control to a robot, especially given fears of cyber-hacking. 首先,人类天生反对将控制权交给机器人,特别是在担心黑客攻击的情况下。Second, for many drivers cars are an extension of their identity, a mechanical symbol of independence, control and freedom. 其次,对于多数驾驶员而言,汽车是他们身份的延伸,是独立、控制和自由的机械象征。They will not abandon them lightly.他们不会轻易抛弃汽车。Third, robots will always be held to far higher safety standards than humans. 第三,针对机器人总是要实施比人类高得多的安全标准。They will inevitably cause accidents. 它们将不可避免的导致意外。They will also have to be programmed to make a calculation that could kill their passengers or bystanders to minimise overall loss of life. 它们还必须经过编程做出可能导致乘客或行人死亡的计算,以将总体人员损失降至最低。This will create a fascinating philosophical sub-school of algorithmic morality. 这将引发一个有趣的关于算法道德的哲学问题。Many of us are afraid that one reckless act will cause an accident that causes a backlash and shuts down the industry for a decade, says the Silicon Valley engineer. That would be tragic if you could have saved tens of thousands of lives a year.我们很多人担心一个冒失的行为将导致一场事故,进而这个行业会遭到抗议并被封杀10年,那位硅谷工程师表示,如果你原本可以每年挽救数万人的生命,那么这种结果将是一场悲剧。Fourth, the deployment of autonomous vehicles could destroy millions of jobs. 第四,自动驾驶汽车的使用可能会葬送数百万个就业岗位。Their rapid introduction is certain to provoke resistance. 这些汽车的快速引入肯定会遭遇抵制。There are 3.5m professional lorry drivers in the US.美国有350万名职业货车司机。Fifth, the insurance industry and legal community have to wrap their heads around some tricky liability issues. 第五,保险行业和司法界必须埋头解决一些复杂的责任问题。In what circumstances is the owner, car manufacturer or software developer responsible for damage?在何种情况下,汽车所有者、汽车制造商或软件开发商要对损害负责?Some governments, such as those of Singapore, China and the UK, as well as several states in the US are creating permissive regulatory and legal environments. 新加坡、中国和英国等一些国家的政府以及美国几个州正在创造宽松的监管和法律环境。Regulators can certainly speed adoption by approving designated lanes for autonomous cars, for example, and devising international safety rules and standards. 监管机构无疑可以加速推动自动驾驶汽车的使用,比如说通过批准建设自动驾驶汽车专用道,以及制定国际安全规则与标准。Conversely, politicians may yet succumb to the pressure of public fears and vested interests and frustrate the roll out of self-driving cars.相反,政治人士仍可能屈于公众担忧以及既得利益群体的压力,阻碍自动驾驶汽车的应用。Autonomous car visionaries may soon be able to perfect the technology. 自动驾驶汽车的梦想家们可能很快就能完善技术。But their success may be determined by how good they are — in Stalinist terminology — as engineers of human souls.但他们能否成功可能取决于他们作为人类灵魂的工程师(用斯大林主义者的术语来说)有多优秀。 /201609/464853

It's the biggest party of the year 全年最大的欢庆聚会 New Year celebrations in London   For lots of people in Britain, the 31st of December, or New Year's Eve as we call it, is the biggest party of the year. It's a time to get together with friends or family and welcome in the coming year.   New Year's parties can take place at a number of different venues. Some people hold a house party; others attend street parties, while some just go to their local for a few drinks with their mates. Big cities, like London, have large and spectacular fireworks displays.  New Year's parties can take place at a number of different venues. Some people hold a house party; others attend street parties, while some just go to their local for a few drinks with their mates. Big cities, like London, have large and spectacular fireworks displays.   New Year celebrations in London   There's one thing that all New Year's Eve parties have in common: the countdown to midnight. When the clock strikes twelve, revellers give a loud cheer, pop champagne corks and give each other a kiss.   They then link arms and sing a song called Auld Lang's Syne, by a Scottish poet called Robert Burns. Not many people can remember all the lyrics, but the tune is well known, so lots of people just hum along.   The parties then continue into the early hours of the morning with lots of dancing and drinking. Because of this, for a lot of people New Year's Day starts with a hangover. Other people might spend the day visiting relatives or friends they haven't managed to catch up with for a while. Whatever happens, New Year's Day tends to be very relaxed.   In Britain, it's popular to make a promise to yourself about something you are going to do, or want to stop doing, in the New Year. This is called a New Year's resolution. Typical resolutions include giving up smoking and joining a gym to get fit. However, the promise is often broken quite quickly and people are back into their bad habits within weeks or days.   New Year's Day is the last bank holiday of the festive season, which means most people have to go to work the next day: bright and fresh and y for the new year ahead!
