Unit 1大规模研究发现：地球的“健康”每况愈下有史以来对地球进行的最大规模的科学分析结果表明，地球上的许多生态系统都达不到标准。

由联合国主持的《千年生态系统评估综合报告》指出，由于不可持续的使用，地球上将近三分之二的用来维持生命的生态系统（包括干净的水源、纯净的空气以及稳定的气候）正遭受破坏。

以上大部分的破坏都是人类在过去的半个世纪里造成的。

据报告分析，随着人类对食物、淡水、木材、纤维以及燃料等资源的需求日趋激增，环境发生了极大的变化，引发了诸如滥伐森林、化学污染等问题。

因此，该报告的作者警告说，照此下去，本已岌岌可危的生态环境将会在21世纪的上半叶进一步恶化。

这项历史性的研究由来自世界95个国家的政府部门以及民间组织的1,300多位科学家共同完成。

四年来，他们考察了地球上许多生物的生长环境、物种以及将他们联系起来的生态体系。

联合国环境规划署对该报告进行了编辑整理并于昨天在中国北京公布了研究结果。

在公布该报告的新闻发布会上，联合国秘书长科菲·安南指出：“只有了解环境及其运作过程，我们才能制定出必要的措施加以保护它。

”他还说，“只有珍惜所有宝贵的自然资源和人类资源，我们才有希望去建设一个可持续发展的未来。

”对社会经济的影响该报告对自然界的大部分生物多样性持悲观态度，地球上可能有10%—30%的哺乳动物，鸟类以及两栖动物濒临灭绝。

这次大规模生态调查是根据安南的《千年发展目标》展开的，该发展目标是由联合国发起的，旨在2015年之前大幅减少饥饿与极度贫困等社会经济问题。

总部位于内罗毕的联合国环境规划署执行主席克劳斯·托普弗说：“从某些方面来说，《千年生态系统评估综合报告》让我们首次认识到生态系统服务功能的经济价值，并使我们对尊重和保护地球生命维护系统有了新的见解。

”目前由于人类社会对地球环境的开发利用，食物供应不断增加，然而增长的速度仍然太慢，难以完成联合国制定的在2015年之前消除全球一半饥饿人口的目标。

科技英语阅读与翻译【牙齿仙女】Primitive peoples believe that hair， nail clippings， and lost teeth remain magically linked to the owner even after they have been disconnected from his body. As any voodoo artist will tell you， if you want to grind someone into powder， you don't need to touch him at all. It's quite enough to stamp on a missing molar and let ;contagious magic; do the rest. This is why peoples all over the world traditionally hide lost body parts， lest they fall into the wrong hands.远古时期的人们认为毛发、剪下的指甲和脱落的牙齿即使离开了人的身体，仍与其主人保持着神秘的联系。

正如任何一个伏都教大师都会告诉你的，假如你想置某人于死地，根本用不着去碰他，只需用脚踩碎那人脱落的一颗臼齿就够了，剩下的事就交给无边的法力去办。

这就是为什么全世界各个民族都习惯于把身体上脱落的东西藏起来，以免落入恶人之手。

American children's ritual of hiding lost teeth under their pillows probably derives distantly from this practice. But there is an obvious difference， for when Suzie conceals her baby milk-tooth， she fully expects it to be found， and by a good magician， not an evil one. Moreover， she expects to be paid for having surrendered it， and at the going rate. Nothing mare clearly suggests the blithe commercial gusto of our culture than this transformation of a fearful superstition into a cheery business transaction。

科技英语课文翻译课文翻译英语Unit 1罗素悖论的提出是基于这样的一个事例：设想有这样一群理发师，他们只给不给自己理发的人理发。

假设其中一个理发师符合上述的条件，不给自己理发；然而按照要求，他必须要给自己理发。

但是在这个集合中没有人会给自己理发。

（如果这样的话，这个理发师必定是给别人理发还要给自己理发）1901年，伯特兰罗素悖论的发现打击了他其中的一个数学家同事。

在19世纪后期，弗雷格尝试发展一个基本原理以便数学上能使用符号逻辑。

他确立了形式表达式（如：应。

一种类比是救护车的汽笛声会改变音高――当它朝你行驶，然后通过你身边接着朝另一个方向去了的时候――他的声波首先是压缩的，接着伸长这些测量给了天文学家一个关于宇宙在不同历史点的膨胀速度的图景。

研究人员还发现宇宙如今正在以前所未有的速度在膨胀。

“一开始我们不情愿相信我们的结果，”加州大学伯克利分校的劳伦斯伯克利实验室的天体物理学家Saul Perlmutter说，他领导的一个竞争性的小组发现了和Schmidt以及Riess 相同的结果。

x =2）和数学特性（如偶数）之间的联系。

按照弗雷格理论的发展，我们能自由的用一个特性去定义更多更深远的特性。

1903年，发表在《数学原理》上的罗素悖论从根本上揭示了弗雷格这种集合系统的局限性。

型的集合系统能很好的用俗称集的结构式来描述。

就现在而言，这种类们可以用x代表整数，通过n来表示并且n大于3例如，小于我7，来表示x={n4，5,6这样一个集合。

这种集合的书写形势就是：我们也可让：n是整数，y={x：3n7}x是美国的一个男性居民。

集合中的对象并不一定是数字。

求的空间。

但是，罗素（和策梅洛一起）发现表面上看，似乎任何一个关于x的描述都有一个符合要a中}导致一个矛盾，就像对一群理发师的描述一样。

x={a：xa它本不再身是在x有致命的打击。

尽管这样，他还不能解决这个问题当罗素发现了悖论，的集合中吗？否定的答案导致了矛盾的出现。

mobile and cellular radio移动和细胞广播in comparison to the relative stability and modest technical developments which are occurring in long haul wideband microwave communication systems there is rapid development and expanding deployment of new mobile personal communication system. These rang from wide coverage area pagers,for simple data message transmission,which employ common standards and hence achieve contiguous coverage over large geographical areas,such as all the major urban centres and transport routes in Europe,Asia or the continental USA.This chapter discusses the special channel characteristics of mobile systems and examines the typical cellular clusters adopted to achieve continuous communication with the mobile user.It then highlights the important properties of current,and emerging,TDMA and code division multiple access(CDMA), mobile digital cellular communication systems.Private mobile radioTerrestrial mobile radio works best at around 250 MHz as lower frequencies than this suffer from noise and interference while higher frequencies experience multipath propagation from buildings,etc,section 15.2.In practice modest frequency bands are allocated between 60MHz and 2GHz. Private mobile radio(PMR) is the system which is used by taxi companies,county councils,health authorities,ambulance services,fire services,the utility industries,etc,for mobile communications.PMR has three spectral at VHF,one just below the 88 to 108 MHz FM broadcast band and one just above this band with another allocation at approximately 170MHz.There are also two allocations at UHF around 450MHz. all these spectral allocations provide a total of just over 1000 radio channels with the channels placed at 12KHz channel spacings or centre frequency offsets. Within the 12khz wide channal the analogue modulation in PMR typically allows 7khz of bandwidth for the signal transmission.when further allowance is made for the frequency drift in the oscillators of these systems a peak deviation of only 2 to 3 khz is available for the speech traffic. Traffic is normally impressed on these systems by amplitude modulation or frequency modulation and again the receiver is of the ubiquitous superheterodyne design,Figure 1.4. A double conversion receiver with two separate local oscillator stages is usually required to achieve the required gain and rejection of adjacent channel signals.One of the problems with PMR receiver is that they are requiredto detect very small signals,typically—120dBm at the antenna output,corresponding to 0.2 uV,and,after demodulating this signal,produce ann output with perhaps 1W of audio equipment, the first IF is normally at10.7MHz and the second IF is very orten at 455KHz . unfortunately,with just over 1000 available channels for the whole of the UK and between 20000and30000issued licences for these systems,it is inevitable that the average busuness user will have to share the allocated channel with other companies in their same geographical area.There are various modes of operation for mobile radio communications networks, the simplest of which is singal frequency simplex. In simplex communication, traffic is broadcast, or one way. PMR uses half duplex(see later Table 15.3) where, at the end of each transmission period, there is a handover of the single channel to the user previously receiving, in order to permit them to reply over the same channel. This is efficient in that it requires only one frequency allocation for the communication link but it has the disadvantage that all units canhear all transmissions provided they are within rage of the mobile and frequencies are allocated for the transmissions. One frequency is used for the forward or downlink, namely base-to-mobile communications. This permits simultaneous two-way communication and greatly reduces the level of interference, but it halves other’s transmissions, which can lead to contention with two mobiles attempting to initiate a call, at the same time, on the uplink in a busy syetem.Although PMR employs relatively simple techniques with analogue speech transmission there have been many enhancements to these systems over the years . Data transmission is now in widespread use in PMR systems using FSK modulation. Data transmission also allows the possibility of hard copy graphics output and it gives direct access to computer services such as databases, etc. Data prembles can also be used, in a selective calling mode, when initiating a transmission to address a special receiver and thus obtain more privacy within the system.15.4.5 Trunked radio for paramilitary use集群无线电的军事使用Another related TDMA mobile radio standard is the European trunked radio(TETRA)network which has been developed as part of the public safety radio communications service(PSRCS) for use by police, utilities, customs office, etc. TETRA in fact is part of wider international collaborations for paramilitary radio use.In these portable radios there is a need for frequency hopping (FH) to give an antieavesdropping capability and encryption for security of transmission to extend military mobile radio capabilities to paramilitary use, i.e. for police, customs and excise offices, etc. these capabilities are included in the multiband interteam radio for the associated public safety communications office in the USA while Europe has adopted the TETRA standard.TETRA is essentially the digital TDMA replacement of the analogue PMR systems. The TETRA standard has spectrum allocations of 380 to 400 and 410 to 430MHz, with the lower band used for mobile transmissions and the upper band for base station use. TETRA mobile have 1 W output power and the base stations 25 W using error with the data throughput rate varying, to meet the required quality of service. TETRA can accommodate up to four users each with a basic speech or data rate of 7.2kbit/s. with coding and signaling overheads, the final transmission rate for the four-user slot is 36 kbit/s. this equipment is large and more sophisticated than a commercial cell phone, and it sells for a very much higher price becase the production runs are much small. However, its advanced capabilities are essential for achieving paramilitary communications which are secure from eavesdropping.15.5 Code division multiple accessAnalogue communication systems predominantly adopt frequency division multiple access (FDMA), where each subscriber is allocated a narrow frequency slot within the available channel. The alternative TDMA(GSM) technique allocates the entire channel bandwidth to a subscriber but constrains the subscriber but constrains the subscriber to transmit only regular short bursts of wideband signal. Both these accessing techniques are well established for long haulterrestrial, satellite and mobile communications as they offer very good utilization of the available bandwidth.15.5.1The inflexibility of these coordinated accessing techniques has resulted in the development of new systems based on the uncoordinated spread spectrum concept. In these systems the bits of slow speed data traffic from each subscriber are deliberately multiplied by a high chip rate spreading code, forcing the low rate (narrowband data signal) to fill a wide channel bandwidth.15.7.2 3G systemsThe evolution of the third generation (3G)system began when the ITU produce the initial recommendations for a new universal mobile telecommunications system(UMTS)[www.] The 3G mobile radio service provides higher data rate services ,with a maximum data rate in excess of 2Mbit/s, but the achievable bit rate is linked to mobility. Multimedia applications encompass services such as voice, audio/video, graphics, data, Internet access and e-mail. These packet and circuit switched services have to be supported by the radio interface and the network subsystem.Several radio transmission technologies(RTT) were evaluated by the ITU and adopted into the new standard, IMT-2000. the European standardization body for 3G, the ETSI Special Mobile Group, agreed on a radio access scheme for 3G UMTS universal terrestrial radio access(UTRA) as an evolution of GSM. UTRA consists of two modes : frequency division duplex(FDD) where the uplink and downlink are transmitted on different frequencies; and time division duplex(TDD) where the uplink and downlink are time multiplexed onto the same carrier frequency. The agreement assigned the unpaired bands (i.e. for UTRA TDD ). TD-CDMA is a pure CDMA based system. Both modes of UTRA have been harmonised with respect to basic system parameters such as carrier spacing, chip rate and frame length to ensure the interworking of UTRA with GSM.The 3G proposal were predominantly based wideband CDMA(WCDMA) and a mix of FDD and TDD access techniques. WCDMA is favoured for 3G in poor propagation environments with a mix of high modest speed data traffic. It is generally accepted that CDMA is the preferred accesstechnique and, with the increase in the data rate, then the spreading modulation needs to increase to wideband transmission.WCDMA is based on 3.84Mchip/s spreading codes with spreading ratio, i.e. , K values, of 4-256 giving corresponging data ratas of 960-15 kbit/s. the upper FDD uplink band I from 1920-1980 MHz is paired with a 2110-2170 MHz downlink. In addition uplink bands II & III at 1850-1910 MHz and 1710-1785 MHz are also paired, respectively, with 1930-1990 MHz and 1805-1880 MHz allocations. the system is configured on a 10 ms frame with 15 individual slots to facilitate TDD as well as FDD transmissions. TDD is more flexible as time-slots can be dynamically reassigned to uplink and downlink functions, as required for asymmetric transfer of large files or video on demand traffic. 3G WCDMA systems use an adaptive multirate speech coder with encoded rates of 4.75-12.2 kbit/s. receivers commonly use the easily integrated direct conversion design, in place of the superheterodyne design . receiver sensitivities are typically -155dBm.The 3GPP2 standard aims to achieve a wide area mobile wireless packet switched capability with CDMA2000 1×EV DO revision A (sometimes called IS-856A). Here 1×refers to the single carrier 1.25 Mchip/s system. It achieves a 3.1 Mbit/s downlink and a delay sensitive services. The 3GPP standard has gone through many release with R4 in 2001 which introduced packet data services and R6 in 2005 to further increase the available data transmission rate . R6 pioneers the use of high-speed downlink packet access and multimedia broadcast multicast services which offer reduced delays and increased uplink data rates approaching 6 Mbit/s.In parallel with the European activities extensive work on 3G mobile radio was also performed in Japan. The Japanese standardisation body also chose WCDMA, so that the Japanese and European proposals for the FDD mode were already aligned closely. Very similar concepts have also been adopted by the North American standardization body.In order to work towards a global 3G mobile radio standard, the third generation partnership project(3GPP), consisting of members of the standardization bodies in Europe, the USA, Japan, Korea and China, was formed. It has merged the already well harmonized proposals of the regional standardization bodies to work on a common 3G international mobile radio standard, still called UTRA. The 3GPP Project 2(3GPP2), on the other hand, works towards a 3G mobile radio standard based on cdmaOne/IS-95 evolution, originally called CDMA2000.比起相对稳定、适度的技术发展是发生在宽带微波通信系统,有长期快速发展和扩大部署的新的移动个人通讯系统。

关于科技的英语演讲稿—Technology带翻译(精选多篇)

关于科技的英语演讲稿—Technology带翻译(精选多篇)演讲稿一：科技改变人们的生活Ladies and gentlemen, good morning!Today, I'd like to talk about how technology has changed people's lives.As we all know, technology has brought about many profound changes in our daily lives. Thanks to the invention of smartphones, we can easily access information, communicate with friends and work remotely, among many other things. Computers and the internet have created new opportunities for businesses and education, and have revolutionized the way we think about work and learning.On the medical front, technology has also had a tremendous impact. For example, medical drones can deliver life-saving supplies to remote areas, and telemedicine allows patients to access medical consultations and treatments from the comfort of their homes. The development of advanced medical technologies, such as robotic surgery and personalized medicine, has also improved diagnostic accuracy and treatment outcomes.In addition, technology is changing the way we interact with the environment. Smart homes, for instance, can reduce energy waste and lower utility bills, and electric cars can greatly reduce air pollution caused by gas-powered vehicles.Overall, technology has greatly impacted our lives in many ways, and its influence will only continue to grow in the future. It's important for us to embrace new technologies and adapt to the changes, but always keep in mind that technology should serve humanity, not dominate it.Thank you!女士们，先生们，早上好！今天我想谈谈科技如何改变人们的生活。

Unit 3当所以人的朋友，是私人的事情吗脸谱网有一个重要的隐私人员，但是我怀疑他将从现在存在10年。

那不是因为脸谱不顾一切去掉隐私保护，但由于脸谱和其他社交网站的普及促进了共享个人的一切事物，消除了从公共分离出私事的结点。

由于共享的个人信息的范围扩展到，几个朋友一起归入脸谱的许多杂项的个人的“朋友”标签中，披露的事情成为很常态和私人的事情变得古怪和不合时宜。

脸谱的年轻成员，是那些高中生或者大学生，以及脸谱开始出现在校园里的时候那些舒适共享任何东西分应届毕业生。

它的老成员是仅仅在2006年打开网络工作场所后加入的。

任何人都调整到一个新的善于自我表达超过沉默的价值体系。

脸谱表示它有1.75亿会员，是世界上最大的社会网络。

但在美国，大多数成员都还比较年轻。

脸谱提供广告给5440万成员的目标，且不分年龄人人共享。

但是，如果广告客户想缩小它的目标观众到那些25岁或更老的，数量就会下降到2880万。

它缩小到30或以上岁数的人，脸谱只有仅仅提供2030万。

许多超过30 岁的人尚未注册，因此脸谱有一个惊人的增长机会。

每个星期，新成员是在美国以百万和全球范围会员和个人网络的增长，似乎不受公司在其短暂的五年历史的失态的影响。

其中的一个实例是在二月，当它与它的服务条款拨弄时。

新的语言似乎断言脸谱“不可撤销”的权利是去保留和使用一个成员的个人信息。

即使成员已经关闭了他或她的脸谱帐户，也应该多一点编辑。

这个强烈抗议是大声的，仅仅一些成员需要增加他们的声音去创建一个喧嚣声，然后脸谱恢复旧的语言。

几天后，它为公司和另一项权利和责任的草案，提供了一个草案原则，对将被批准的成员。

脸谱提供给成员很多隐私选项。

我算43个可以调整的设置，不包括一堆限制的、可以看出一个人的脸谱朋友安装软件应用程序的信息。

脸谱的默认设置是为在某些方面的新的帐户保护用户。

例如，在一个人的个人资料只限于朋友和其他人的学校，工作场所或地理网络。

它不是朋友的朋友访问。

Unlocking the Climate Puzzle解开气候之谜(1)Life has prospered on this planet for nearly four billion years. In that time, climate had fluctuated drastically, from ice ages lasting tens of thousands of years to epochs of steamy heat. With each change, sundry species have benefited and flourished.Others adapted, faltered， or died. Now, many experts believe， humans are imperiling their own ecological niche with the threat of global warming. The vaporous by—products of civilization， in the form of greenhouse gases such as carbon dioxide (C0₂), have trapped enough heat in the atmosphere to raise Earth's average surface air temperature a half degree Celsius (one degree Fahrenheit) during this century. If the trend continues， it could alter climate patterns worldwide-thawing glaciers， boosting sea level, scorching plains into deserts, and shifting vegetation zones。

By far the most common genetically modified (GM) organisms are crop plants. But the technology has now been applied to almost all forms of life, from pets that glow under UV light to bacteria which form HIV- blocking "living condoms" and from pigs bearing spinach genes to goats that produce spider silk.到目前为止最常见的转基因生物体是农作物。

然而，这项技术现在已经应用于几乎所有形态的生命,从宠物在紫外线照射下发光到构成HIV-blocking 的“活的安全套”的细菌,从继承菠菜基因的猪到生产蜘蛛丝的山羊。

GM tomatoes, as puree, first appeared on British supermarket shelves in 1996 (a different fresh GM tomato first appeared in the US in 1994), but the consumer furore that surrounded GM technology did not erupt until February 1999.This was because a controversial study suggested that a few strains of GM potatoes might be toxic to laboratory rats.Those experiments, subsequently criticised by other experts, were carried out in Scotland by biochemist Arpad Pustzai.转基因西红柿酱, 在1996年第一次出现在英国的超市货架上(1994年不同的新鲜番茄在美国首次出现),但直到1999年2月消费者对基因技术的愤怒才爆发。

Unit 1 EnvironmentEarth’s Health in Sharp Decline, Massive Study Finds大规模研究发现：地球的“健康”每况愈下The report card has arrived from the largest ever scientific Earth analysis, and many of the planet’s ecosystems are simply not making the grade.有史以来对地球进行的最大规模的科学分析结果表明，地球上的许多生态系统都达不到标准。

The UN-backed Millennium Ecosystem Assessment Synthesis Report found that nearly two-thirds of Earth’s life-supporting ecosystems, including clean water, pure air, and stable climate, are being degraded by unsustainable use.由联合国主持的《千年生态系统评估综合报告》指出，由于不可持续的使用，地球上将近三分之二的用来维持生命的生态系统（包括干净的水源、纯净的空气以及稳定的气候）正遭受破坏。

Human has caused much of this damage during the past half century. Soaring demand for food, fresh water, timber, fiber and fuel have led to dramatic environmental changes, from deforestation to chemical pollution, the report says. The already grim situation may worsen dramatically during the first half of the 21st century, the report’s authors warn.以上大部分的破坏都是人类在过去的半个世纪里造成的。

Teach Predictions for 20101. Finally, Apple Unveils the TabletOfficially, Apple has never said a word about making a tablet computer. Yet for months, everyone in tech has been talking and writing and arguing about the Apple tablet as if it's already here. The product has already received more press than most products that actually exist. Bloggers debate its faults and flaws, its strengths and Shortcomings--such is life in the weird and wonderful world of Apple. And this does not happen by accident. Apple orchestrates this stuff. It did the same thing with the iPhone, remember? For a year before the prodtict was unveiled, rumors circulated and fake prototype photos popped up all over the place. Ifs all about creating hype, and wrapping a product in a cloud of mystery and drama, so that by the time you do unveil it people are dying to buy it just tosee what all the fuss is about.The great thing about Apple, however, is that usually the products live up to the hype. Certainly the iPhone has. Arguably, it is the single most important tech product of the past decade. Will the tabletbe as profound? We think it will be. Amazon's Kindle has pioneered the market for a portable reading device. But Kindle is far from perfect. Our bet is that Apple enters this space the way it did with the iPod and iPhone: it lets others do the pioneering work and make all the mistakes, then comes along with a product that blows the predecessors away. Better design. Better build quality. Better service. And a user interface experience that’s light years ahead of everyone else's on the planet.2. Murdoch Pulls out of GoogleThe biggest, most powerful, and once-thought-to-be indestructible print media outlets have arrived at their moment of reckoning. For a decade, the likes of the Los Angeles Times, The Washington Post, and The New York Times (not to mention innumerable other oudets), have offered up their best work on a silver, online platter-- for free. Look at where it got them. The first is in jeopardy of closing up shop, the Post has shuttered its domestic bureaus, and the Gray Ladys just eliminated some 100 newsroom jobs, the second such move in two years. Enter Rupert Murdoch, theoutspoken Aussie head of News Corp whose empire spans from the Times of London to the most august business publication in the United States, The Wall Street Journal. For months now, he has been ranting about the free consumption of news online. His radical idea? Murdoch wants to stop Google from indexing his sites, and he wants Microsoft to pay for the privilege instead. In other words, he wants someone to pay for the stuff his journalists produce.A chorus of bloggers is crying that the old man's thinking cuts against the force of history--namely, that information wants to be free, and that any future-minded company ignores that fact at its peril. Techdirt says the news baron is a hypocrite. Boing Boing says Murdoch's threat to block searches and shroud his sites with paywalls is nothing more than a bluff. Think again. This isn't a doddering old coot who doesn't get the Web. Murdoch is a savvy business-man who just might lead an industry back into the reality-based community. With billions in cash on hand, he can afford short-term losses as his properties experiment with strategies that do not involve the essential untenability of giving the product away. And once he proves that a news publication can poke Google in the eye and survive, others will follow suit. After all, if they don't, Murdoch may be the only one left standing.3. Malw Disrupts FacebookWhen it comes to malware, the law of gravity is this: the bad guys go where the money is. That's why threats to computer users have evolved from viruses to botnets and phishing attacks--each iteration is more likely to produce profit. How does a piece of malware make money, exactly? In a number of ways, from rifling through your files for bank-account information and credit-card numbers, to turning your computer into a spam factory. The follow-the-money rule also helps explain why there aren't many threats for *Mac computers. They may have some security advantages over PCs, but mostly their market share isn't big enough to be worth malware creatorg time. )It follows that as we conduct more of our lives online, malefactors will follow us there. And where is the biggest action on the Web today? Facebook, which just signed up its 350 millionth user and shows no sign of slowing down. Facebook has seen malware before; the latest threat is an especially virulent edition of the "Koobface" worm that has bedeviled the social network for months. It's going to get worse from here. Facebook has a team of smart engineers dedicated to keeping malicious activity off the site, but with the network ballooning in size, they'll need to redouble their defenses in even greater proportion.4. Starbucks Will Stalk YouPrivacy is so passe. We've become addicted to broadcasting our lives to the world, and the mobile phone is our greatest enabler. That's especially true now that GPS is a standard feature. And today's hottest startups are racing to become the ankle bracelet of choice, doing everything they can to track our every move and indulge our shout-it-from-the-rooftops exhibitionism. Location-aware services like Foursquare, which awards points every time you check into a bar or restaurant, have become staples among the early-adopter crowd. Meanwhile, Twitter6 has added geolocation to its service, meaning each tweet is like a thumbtack on the map of your daily travels. Rumors have it that Facebook, with its 350 million users, is heading in the same direction. It's only a matter of time before advertisers follow. You can almost hear the screams of joy coming from marketing departments nationwide: soon companies will be able to target their ad campaigns based not just on who you are, but where you are. Passing by a Starbucks? Your phone just offered you 10 percent off a peppermint latte!5. Movie Downloads Stall Blu-rayBlu-ray may have won the war with its rival, HD-DVD---but does anyone care? While consumers were waiting for the two formats to duke it out--nobody wanted to plunk down several hundred bucks on a losing technology--they discovered that downloading movies to their homes has matured into a great way to watch their favorite titles. A Harris Interactive poll in June found that only 7 percent of consumers without Blu-ray players planned on buying one in the next year. Whafs holding back a format that everyone agrees is showstoppingly gorgeous to watch? Money is a big part of it, of course. Getting video over the Internet through iTunes9 or Amazon Video on Demand can be much cheaper than purchasing physical copies. Sometimes the value is truly insane: all it costs to binge out on seasons one, two, and three of Friday Night Lights is $ 8.99. That's the price of the cheapest monthly subscription to Netflix, which allows unlimited streaming of some shows and movies to your PC, or to your big screen if you own an Xbox 360, PlayStation 3, newer TiVo, or a similar device,Yes, a Blu-ray disk provides better quality picture and sound. But as Wired magazine argued in a recent cover story, consumers are enjoying a "Good Enough Revolution" : we're nuts about MP3s, even if they sound kind of crappy, and we can't watch enough YouTube clips, even though they're pixellated and choppy. The feverish pursuit of top quality is no longer our only concern. Sometimes convenience matters more.6. Your Phone Replaces Your WalletDuring its most recent pledge drive, the popular public-radio program This American Life followed a familiar script, exhorting its users to chip in $10, $ 5, even just $1, to help pay for its weekly broadcast. The pitch wasn't new, but one of the payment methods was instead of heading to your computer and entering your credit-card information, you could simply send $ 5 to the show via text message. Long promised, never realized, mobile payments will finally take off in the U. S. in 2010. Already the sector is a beehive of activity, with companies like Zong and mPayy enabling cus tomers to pay for online purchases with only a phone number. Obopay, another mobilepayments company, received $ 35 million from Nokia in 2009, and it will have a wide rollout on that company's phones. Perhaps the best sign that the sector is poised for takeoff is that Twitter creator and tech superstar Jack Dorsey has set his sights on it. His new company, Square, launched in December, allows merchants to accept credit-card payments with cell phones. True, Square doesn't untether us from plastic just yet, but it's only a matter of time before "Cash or credit?" becomes "Cash or cell?"7. Facebook Goes PublicAt only 25 years old, Facebook's Mark Zuckerberg has turned his donn-room idea into a global empire. Might he identify with Alexander the Great, who wept at the size of his dominion because there were no more lands left to conquer? Not just yet: he can still take the company public. In November, the social-networking company took a major step toward that event by announcing that it was creating two classes of stock: one class suitable for sale in an initial public offering, and one that is vested with 10 times the voting power. An IPO under those conditions would flood the company with cash while keeping control firmly in Zuckerbergs hands. If that sounds familiar, it's because the strategy is the same one used by Google before it went public in 2004. Zuckerberg is as cutthroat and super-ambitious as he is socially awkward that is to say, very--and he would stand to become an actual billionaire, not just a virtual one. His Personal wealth has yo-yo'd in line with various private valuations of his company over the years. Facebook also announced this year that it is cash-flow positive, and a successful IPO would cement the site as a viable business, while archrival Twitter stillscrambles for a business model.8. Twitter Use FlatlinesTwitter is almost synonymous with explosive growth. But there are signs that 2009's darling of the Internet has already begun to level off, a reversal that would have seemed impossible not long ago. In February 2oo9, Nielsen Online reported that Twitter's 7 million unique visitors constituted more than 1,000 percent growth in just a year's time. Ashton Kutcher, after beating CNN to the million-follower mark in a neckand-neck race, began blasting past later milestones with ease. (He's now at 4.1 million followers. ) And when Oprah Winfrey embraced the service in April, Twitter's popularity simply hockey-sticked.There were skeptics all along-- Nielsen also reported last spring that 60 percent of Twitter users failed to return after one month but excitement about the new mediurm's potential made them easy to dismiss. Now the data have become difficult to ignore. Twitters U. S. traffic actually declined from September to October, according to a range of measures. We're by no means Twitter haters--here's proof--but it seems clear that the service is in for a period of modest performance, as sign-ups of new users are measured against better estimates of existing users who neglect their accounts. One of the things that has made Twitter so successful is its wide-open API; ironically, that same transparency can provide a reality check on the number of people who have let their accounts go totally dormant who began tweeting during the Oprah bubble, but turned out to be making just a short stop at the birdbath.9. Microsoft Pushes Out Steve BallmerBallmer's 10th anniversary as CEO of Mierosoft arrives in January, but ifs hard to imagine he'll be celebrating. Mierosoft stock has dropped by nearly 50 percent on his watch, lagging not just other teeh eompanies but even the Dow Jones industrial average. Distracted by the Windows Vista fiasco, Ballmer has missed every big new tech market of the past decade. Google won the race for Internet search and keyword advertising. Apple won in MP3 players and online music sales, and now holds the high ground in mobile phones, while Windows Mobile fades away. Microsoft's Zune music player is a dud. Bing, Microsoft's search engine, will never catch Google. Ballmer is said to be a brilliant guy, but he got a black eye for the way he blundered and blustered and finally botched an attempted acquisition of Yahoo. He's a screamer and a bit of a bully--not the easiest guy to work for. If Microsoft were any other company, this guy would be in trouble. But the catch is, Ballmer was put into the job by Microsoft founder Bill Gates, and the two have been pals since their undergraduate days at Harvard. If Gates wants to get rid of Ballmer, he' 11 have to craft some kind of graceful exit that lets his buddy save face. Another problem: there's no heir apparent on the management team. Nevertheless, investors must be getting restless. Soon they'll start calling for a shake-up.10. Google Faces Antitrust SuitThe Feds are already looking at Google on a variety of fronts. Its deal with book publishers has drawn scrutiny. In 2009 it was hassled by the Federal Trade Commission over possible anticompetitive connections because it shared two board members with Apple, a situation that got resolved when Google CEO Eric Schmidt quit Apple's board, and Arthur Levinson, an Apple board member, quit the Google board. Regulators freaked out again when Google tried to make a search partnership with Yahoo. Supposedly the Feds were ready to bring charges, but then Google walked away from the deal.After facing this scrutiny in the past year, Google has launched a kind of ongoing publicity campaign, wooing the media and hoping to convince people that it isn't really a big bad company. It likes to say that it's operating in a highly competitive field and that its users can leave with the click of a mouse. But the fact is, Google handles two thirds of all searches in the United States. Whether that can legally be defined as a "monopoly" and whether Google can be shown to have abused its powerful market position remains to be seen. But regulators here and/or in the European Union will find Google so tempting a target that they will not be able to resist bringing a case to find out.Addicts of the Information AgeAmong everybody from our leaders to our teenagers, no habit is spreading faster than being connected 24/7 via a smart phone.[2] Its penetration in the U.S. is estimated at 18%, and it seems that everywhere you turn, people are using their smart phones in new ways and in new places. Samsung recently estimated that it expects 500 million global smart-phone users by 2012. Actual phone calls are becoming extinct compared with handheld texts and email messages--whoever thought people would prefer typing to talking? But the evidence appears to say they do.[3"] This has also given rise to a group of people--the top 10% of smart-phone users--who just can't stop. They are the smartphoniacsI, the true addicts of the information age.[4] Here are five tell-tale2 traits of Smartphoniacs :Do they take their smart phones with them when they get up from the table to go to the restroom---and do they take an awful lot of trips there?Do you receive messages from them while you know they are driving (increasingly being harmed in state after state), or at midnight on Saturday night?Do they come up with excuses in the middle of a conversation to pull out their smart phone--something like "let me jot something you said down so I don't forget it", and then sneak a look at all their messages?Are they suffering from sprained or elongated thumbs?Do they openly use their smart phones in inappropriate places, such as first dates, at Rosh Hashanah4 or Christmas dinner, in hospital delivery rooms, or on job interviews?[5 ] If your "friend" fits four out of five of these, then he or she is a smartphoniac. If he fits only two or three of them, he is just another typical user who stays connected on the street, in meetings and at the movies.[6] As these devices pop up everywhere, there has been a recent spate of articles about smart-phone "manners"--as if using your phone when your boss, or your mother, is talking to you is just a matter of poor training on their part. I don't think your boss or your mom ever said "go ahead, text while I'm talking to you". So it's just not a matter of manners. Ifs much more the result of a deeper disconnect anxiety, an irrepressible fear that you will miss something if you put it away.[7] I once worked with a candidate for Senate who emailed me from the podiums during a debate. Many 'CEOs communicate today primarily from their smart phones. Hillary Clinton and Barack Obama used them on the campaign trail, while John MeCain didn't.[8] The famed red phone to call the Russian premier in the event of a national security emergency could now be replaced by a red smart phone. Imagine if the world's top leaders were all connected bysmart phones and they communicated directly and frequently about issues of mutual concern. It would revolutionize diplomacy.[9] But Smartphoniacs are an eclectic mix of the successful and powerful, busy professionals, teenagers and college students. All of them commtmicate incessantly.[10] In Korea, more than three in 10 youths who carry mobile phones are said to be addicted. In Germany, there are an estimated 380,000 texting addicts—folks who withdraw from the very family and friends their machines were supposed to connect them to. While there hasn't been a formal study of Smartphoniacs in America, we know that between the second quarter of 2007 and the second quarter of 2008, the North American smart-phone market grew 78.7%. About 139.3 million smart phones were sold world-wide last year, and half of U. S. smart-phone users report using their devices more today than they did just three months ago.[11] Last month, the National Texting Championship award and its $ 50,000 grand prize went to a 15-year-old who texts 500 times a day. A recent poll found that 42% of teens can text with their eyes closed. And based on other studies on the intensity of smart-phone use, we can guess that Smartphoniacs skew male, affluent and well-educated. Not since the television has any invention changed the lifestyle habits of Americans more than the smart phone. The recent movie Seven Pounds detailed the guilt of an executive who caused a fatal car crash because he emailed while driving.[12] To be sure, there are forces calling for temperance7. Some people refuse to date people who use smart phones. Many parents just say no. Legislators are getting into the act to protect public safety. But for the most part, Americans of every age and stage are wrapping themselves in apps, chcks and instantaneous communication as part of a social network. And some small but significant percentage of this group is going to take a one-way slide to the bottom, where the compulsion to use their smart phones is so strong that they can only hope their batteries last long enough to text a cry for help.[13] We're not far away from Smartphoniacs Anonymous or Mothers Against Smart Phones. We've been through this with TV, the Intemet and videogames. In the end it all works out and we successfully integrate them into our lives, even though we are never again the same. At least with smart phones, with all their usage counters, we will be able to tell who has recovered from the binges.。

科技英语原文及简单翻译How ASIMO WorksIntroduction to How ASIMO WorksWant a robot to cook your dinner, do your homework, clean your house, or get your groceries? Robots already do a lot of the jobs that we humans don't want to do, can't do, or simply can't do as well as our robotic counterparts.Honda engineers have been busy creating the ASIMO robot for more than 20 years. In this article, we'll find out what makes ASIMO the most advanced humanoid robot to date.The Honda Motor Company developed ASIMO, which stands for Advanced Step in Innovative Mobility, and is the most advanced humanoid robot in the world. According to the ASIMO Web site, ASIMO is the first humanoid robot in the world that can walk independently and climb stairs.Rather than building a robot that would be another toy, Honda wanted to create a robot that would be a helper for people -- a robot to help around the house, help the elderly, or help someone confined to a wheelchair or bed. ASIMO is 4 feet 3 inches (1.3 meters) high, This allows ASIMO to do the jobs it was created to do without being too big and menacing.ASIMO's Motion: Walk Like a HumanHonda researchers began by studying the legs of insects, mammals, and the motion of a mountain climber with prosthetic legs to better understand the physiology and all of the things that take place when we walk -- particularly in the joints. For example, the fact that we shift our weight using our bodies and especially our arms inorder to balance was very important in getting ASIMO's walking mechanism right. The fact that we have toes that help with our balance was also taken intoconsideration: ASIMO actually has soft projections on its feet that play a similar role to the one our toes play when we walk. This soft material also absorbs impact on the joints, just as our soft tissues do when we walk.ASIMO has hip, knee, and foot joints. Robots have joints that researchers refer to as \degrees of freedom.\A single degree of freedom allows movement either right and left or up and down. ASIMO has 34 degrees of freedom spread over different points of its body in order to allow it to move freely. There are three degrees of freedom in ASIMO's neck, seven on each arm and six on each leg. The number of degrees offreedom necessary for ASIMO's legs was decided by measuring human joint movement while walking on flat ground, climbing stairs and running.ASIMO also has a speed sensor and a gyroscope sensor mounted on its body. They perform the tasks of:? ?sensing the position of ASIMO's body and the speed at which it is moving relaying adjustments for balance to the central computer These sensors work similarly to our inner ears in the way they maintain balance and orientation.ASIMO also has floor surface sensors in its feet and six ultrasonic sensors in its midsection. These sensors enhance ASIMO's ability to interact with its environment by detecting objects around ASIMO and comparing gathered information with maps of the area stored in ASIMO's memory.To accomplish the job our muscles and skin do in sensing muscle power, pressure and joint angles, ASIMO has both joint-angle sensors and a six-axis force sensor.Unless you know a lot about robotics, you may not fully grasp the incredible milestone it is that ASIMO walks as we do. The most significant part of ASIMO's walk is the turning capabilities. Rather than having to stop and shuffle, stop and shuffle, and stop and shuffle into a new direction, ASIMO leans and smoothly turns just like a human. ASIMO can also self-adjust its steps in case it stumbles, is pushed, or otherwise encounters something that alters normal walking.In order to accomplish this, ASIMO's engineers had to find a way to work with the inertial forces created when walking. For example, the earth's gravity creates a force, as does the speed at which you walk. Those two forces are called the \inertial force.\ground, called the \posture has to work to make it happen. This is called the \zero moment point\(ZMP). To control ASIMO's posture, engineers worked on three areas of control:? ?Floor reaction control means that the soles of the feet absorb floor unevenness while still maintaining a firm stance.Target ZMP control means that when ASIMO can't stand firmly and its body begins to fall forward, it maintains position by moving its upper body in the direction opposite the impending fall. At the same time, it speeds up its walking to quickly counterbalance the fall.?Foot-planting location control kicks in when the target ZMP control has been activated. It adjusts the length of the step to regain the right relationship between the position and speed of the body and the length of the step.ASIMO's Motion: Smooth MovesASIMO can sense falling movements and react to them quickly; but ASIMO's engineers wanted more. They wanted the robot to have a smooth gait as well as do something that other robots can't do -- turn without stopping.When we walk around corners, we shift our center of gravity into the turn. ASIMO uses a technology called \predictive movement control,\Intelligent Real-Time Flexible Walking Technology or I-Walk, to accomplish that same thing. ASIMO predicts how much it should shift its center of gravity to the inside of the turn and how long that shift should be maintained. Because this technolgy works in real time, ASIMO can do this without stopping between steps, which other robots must do.Essentially, with every step ASIMO takes, it has to determine its inertia and then predict how its weight needs to be shifted for the next step in order to walk and turn smoothly. It adjusts any of the following factors in order to maintain the right position:? ? ? ?the length of its steps its body position its speedthe direction in which it is steppingWhile reproducing a human-like walk is an amazing achievement, ASIMO can now run at speeds up to 3.7 miles per hour (6 kilometers per hour). In order to qualify as a true running robot, ASIMO must have both feet off the ground for an instant in each step. ASIMO manages to be airborne for .08 seconds with each step while running. Honda engineers encountered an entirely new set of challenges while trying to give ASIMO the ability to run. They gave ASIMO’s torso a degree of freedom to aid in bending and twisting so that the robot could adjust its posture while airborne. Without this ability, ASIMOwould lose control while airborne, possibly spinning in the air or tripping when landing.In order to make turns smoothly while running, the engineers enhanced ASIMO's ability to tilt its center of gravity inside turns to maintain balance and counteractcentrifugal force. ASIMO could even anticipate turns and begin to lean into them before starting the turn, much like you would if you were skiing or skating.ASIMO如何工作介绍如何工作。
