参考译文Unit 1课文A石油1油，和煤一样，存在于沉积岩中，而且可能由死去很长时间的生物有机体形成。
含有石油的岩石几乎都来源于海洋，所以形成石油的有机物一定是海洋生物，而不是树木。
2 石油，并不是来自于逐渐积聚的木质物质，而可能是来自于逐渐积聚的海洋生物的脂肪物质。
比如浮游生物：大量浮游在海水表层的单细胞生物。
3 有机物的脂肪物质主要由碳氢原子组成，因此并不需要太多的化学变化就可以形成石油。
生物有机体只需在缺氧的条件下沉积到海湾浅水处的淤泥里。
其脂肪不是分解腐烂，而是逐渐积聚，并在深层的淤泥里圈闭起来，进而经过细微的原子重组，最终形成石油。
4 油比水轻，呈液态，会经由上方覆盖的孔隙性岩石向上渗透，在地球上有些地区到达表层，古人将这些表层石油称为沥青、柏油或异庚烷。
在古代和中世纪，这些石油油苗常被看作药品而不是燃料。
5 当然，表层的油苗数量很少。
而石油油藏上方有时覆盖的是非孔隙性岩石。
石油向上渗透抵达该岩石，然后在岩石下方逐渐积聚形成油层。
若在上方的岩石上钻个孔，石油就可以通过该孔向上迁移。
有时压力过大，石油会向高空喷出。
1859年在宾夕法尼亚州，由埃德温·德雷克成功打出第一口井。
6 如果可以发现一个合适的地点（勘探人员已经识别出地下可能圈闭有石油的地层结构），那么就很容易抽取这一液体燃料，这要比派人到地下把大块的固体煤炭砍成小块要容易得多。
而且一旦获得石油，可以通过地上管道运输，而不必像煤一样，由运货车经过繁重的装卸任务来运输。
7 石油便于抽取，易于运输，促进了石油的应用。
石油可以蒸馏成不同的馏分，每种馏分均由特定大小的分子组成，分子越小，该馏分就越容易蒸发。
8 到19世纪下半叶，最重要的石油馏分是由中等大小的分子构成的煤油，它不易蒸发，被用于照明。
9 然而，到19世纪末人们研制出了内燃机。
内燃机是通过在汽缸里将空气与可燃气体混合，产生爆炸来提供动力的。
最便利的可燃气体是汽油——石油的又一馏分，由小分子构成，容易蒸发。

Types of SustainabilityThe four types of sustainability include human, economic, social, and environmental. All four are required to maintain the entirety of life on Earth. Although interconnected, it is important to note the differences of each in terms of its nature and requirements.Types of Sustainability / HumanThe very basic need of human sustainability is good reproductive health and safe childbearing. Those that reproduce have the responsibility of caring for their children, giving them access to proper education, and promoting their health and wellness. At some point, the children should have enough skills and knowledge such that they can sustain their own way of life. It is at that point that they become considered as productive human capital as well as individuals that can go through the process of reproduction and rearing. As long as this process is maintained at a rate that all human systems can support, human sustainability should be no cause for concern.Types of Sustainability / EconomicIn simple terms, economic sustainability is having a set amount of capital for a certain period. Those who consume that capital must also conserve it so that they will continue to enjoy it towards the end of the specified period. This means that we must preserve all our resources as we consume them so that human beings in the future can enjoy them as well. To achieve this, we must regenerate our resources at a rate that is equal to or faster than our consumption.Types of Sustainability / SocialSocial capital is an important aspect of sustainability because it is through communities and civil societies that humankind can easily and inexpensively work together. Without proper levels of social capital, it can easily deplete and violence as well as mistrust can take over. When that happens, societies and everything else that depends on them will be destroyed. Through proper maintenance of and adherence to laws, rules, and values that societies have developed for the common good, social sustainability can be achieved.Types of Sustainability / EnvironmentalEnvironmental sustainability is important because it involves natural resources that human beings need for economic or manufactured capital. Materials taken from nature are used for solutions that address human needs. If nature is depleted faster than it can regenerate, human beings will be left without raw materials.Furthermore, environmental sustainability also involves ensuring that waste emissions are at volumes that nature can handle. If not, all humans and other living things on Earth can be harmed to the point of extinction.可持续性分类四种可持续性包括人类可持续性，经济可持续性，社会可持续性和环境可持续性。

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。

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.。

We use touch screens everywhere: tourist kiosks, automatic teller machines, point-of-sale terminals, industrial controls. Half a dozen vendors, plus in-house departments at major manufacturers, produced $800 million worth in 2000. The market is growing because the interfaces are easy-to-use, durable and inexpensive.
Touch screens employ one of three physics principles for detecting the point of touch. Pressing a “resistive” design with a finger or other stylus raises a voltage. In “capacitive” models, a finger draws a minute current (this method is often used for cursor pads on notebook computers). In other designs, a finger or stylus interrupts a standing pattern of acoustic waves or infrared lights that blanket the surface.
Resistive screens are the oldest, most widely used and least expensive, and they work with any stylus (finger, pen). Capacitive screens must be touched by a finger or an electrically grounded stylus to conduct current. Wave screens are the newest and most expensive. Surface acoustic wave screens must be touched by a finger or a soft stylus such as a pencil eraser to absorb energy; infrared screens work with any stylus. The different technologies may be used in the same applications, although pros and cons lead to prevalent combinations: resistive screens for industrial controls and Palm Pilots; capacitive screens for slot machines; wave screens for A TMs and indoor kiosks.
Most people are unaware of the type of screen they are using. But tricks can help you tell, according to Frank Shen of Elo TouchSystems in Fremont, Calif., the largest U.S. maker. Push the screen lightly with your fingernail (not your skin). If it responds, it could be resistive or infrared. In this case, place two separated fingers aga inst the screen at the same time. If the cursor moves beneath one finger, the unit is infrared (software registers the first touch); if the cursor moves between the fingers, it is resistive (the points are averaged). If the unit does not respond to your fingernail, again place two separated fingers against it. If the cursor moves beneath one finger, the unit is acoustic wave; if the cursor moves between the fingers, it is capacitive.
触控荧幕的应用非常广泛，例如游客导览系统、自动柜员机、销售点终端机、工业控制系统等。
在2000年，六家专门厂商加上几家大公司的触控产品部门，总产值高达八亿美元。
由于这种介面使用方便、经久耐用，而且花费不高，因此市场还在成长之中。
触控荧幕可依其侦测触控点的物理原理，分为三种：电阻式荧幕，用手指或其他触头轻按就会产生电压；电容式荧幕，手指会吸取微小的电流（常用于笔记型电脑的触控板）。
至于第三种波动式荧幕，则是用声波或红外线覆盖整个表面，而手指或触头会阻断这些驻波图样。
电阻式荧幕是历史最久、用途最广，也是价格最低的一种，而且任何触头（无论手指或笔尖）都可以使用。
电容式荧幕必须使用手指，或是接有地线的触头，以便传导电流。
波动式荧幕则是最新且最昂贵的类型。
表面声波荧幕必须用手指或软式触头（例如铅笔上的橡皮擦）轻触，以吸收表面能量；红外线触控荧幕则可使用任何触头。
在实际应用上，可以同时选用好几种技术，不过基于各技术的优缺点，通常导致以下的组合：工业控制系统和掌上型电脑Palm Pilot使用电阻式，自动贩卖机使用电容式，自动柜员机及室内资讯站使用波动式。
但是大多数人并不清楚，自己所使用的荧幕是什么类型。
沈辉斌任职于美国最大的触控荧幕制造商──位于加州夫利蒙市的“易触控系统公司”，他提供了以下的辨别诀窍。
你可用指甲（而不是皮肤）轻压荧幕，假如荧幕有反应，就可能是电阻式或红外线式荧幕。
果真如此，再同时用两根手指分别轻压荧幕上两点。
假如游标移到其中一根手指下方，这装置使用的就是红外线（软体只记录第一个接触点）；假如游标移到两根手指之间，荧幕就是电阻式（两个接触点皆有影响力）。
假如这个装置对指甲毫无反应，你的下一步还是用两根手指分别轻压荧幕上两点。
这时候，如果游标移到其中一根手指下方，那么这荧幕使用的原理是声波；假如游标移到两根手指中间，它就是电容式触控荧幕。
