Here’s the Totally Amazing Wonder Material That Could Revolutionize Technology
A．In the technology industry,every new product or service seems to come with the promise that it is an innovation with the potential to change the world．Graphene(石墨烯)，a form of carbon，might actually do just that．
B．“Graphene is a wonderful material，”Jeanie Lau，a professor of physics at the University of California at Riverside，told Fortune．“It conducts heat 10 times better than copper and electricity 100 times better than silicon，is transparent like plastic，extremely lightweight,extremely strong,yet flexible and elastic．In the past decade，it has taken the scientific and technology communities by storm，and has become the most promising electronic material to supplement or replace silicon．”
C．Graphene has already found its way into a number of compelling applications，Lau said．For instance，“since it is both transparent and electrically conductive—two attributes rarely found in the same material in nature—it has tremendous potential as the transparent electrode in monitors．displays；solar cells，and touch screens，”she explained．“Companies such as Samsung that invest heavily in this area have already secured patents，produced prototypes，and are expected to bring products to market in a few years．”Wearable electronic devices，aviation components，broadband photodetectors(光電檢測器)，radiation-resistant coatings，sensors，and energy storage are among numerous other areas of active research．Lau said．
D．For many researchers and investors，the ultimate application is graphene-based transistors，the building blocks of modem electronics．But getting there may take some time．
A child of graphite
E．First produced in a lab back in 2004，graphene is essentially a single layer of pure carbon atoms bonded together in a honeycomb lattice so thin it’s actually considered two-dimensional．“We generally regard anything less than 10 layers of graphene as graphene；otherwise，it’s graphite，”said Aravind Vijayaraghavan，a lecturer in nanomaterials at the University of Manchester．
F．Even“graphene”is a bit of an umbrella term．“To oversimplify,there are two major types of graphene，”Michael Patterson，CEO of Graphene Frontiers，said．The first：“Nanoplatelets，”which are powders or flakes made from graphite．These have been around for a while and are“not really super-sexy,”Patterson said．“You mix them into polymers(聚合物)or inks or rubbers to make them conductive．”In flake form，graphene is already on its way to becoming a commodity,Patterson added．The other type—in sheet or film form—is where graphene’s biggest promise lies．Graphene sheets have“incredible potential for electronics，”Patterson said．In the near term，that potential may manifest in situations where the quantity requirements are“not that great”and where quality or conductivity doesn’t have to be as high，such as in basic touch-screen applications，he said．Products that use graphene in this way could arrive to market in the next six to 1 2 months．
G．Looking a little further out，graphene can be employed in membranes used for water desalination．Lockheed-Martin already has a patented product known as Perforene．“It’s real and it works，but it won’t be economically viable until the product reaches an industrial scale where the cost is measured in pennies per square inch”rather than dollars or tens of dollars per square inch，Patterson explained．
“That’s where we’re working today．”
‘It’s expensive and low-capacity’
H．But use of graphene in semiconductors—the technology’s Holy Grail—is likely a decade away．“Many of the challenges presented by graphene are common to most new materials，”Paul Smith,a patent associate with the Intellectual Property Law Group at Fenwick & West，told Fortune．“The trick is figuring out how to synthesize graphene in a way that first is manufacturable beyond lab scale；second，preserves the desirable properties of the material；and third，can be integrated into a product or technology．”
D．Synthesizing graphene in sheet form is considerably more expensive and time-consuming than producing graphene flakes．Whereas the latter typically involves a“quick and dirty”process by which bulk graphite is disassembled into millions of tiny pieces，Lau explained，large sheets of graphene are carefully“grown”on substrates(基板)such as copper，germanium，or silicon carbide．
J．Graphene sheets are also prone to defects and“very difficult to make in good quality,”Ron Mertens，owner and editor of Graphene-Info．tom，said．Production capacity is also very limited．“There are thousands of small companies that can make graphene，but it’s expensive and low-capacity,”Mertens said．alround wafer measuring one inch in diameter,for instance，costs about$1 00，he added．
K．An even thornier obstacle on the way to graphene transistors is the fact that the material has no“band gap，”an essential property that allows transistors to be turned on and off without leaking electronic charge in the“off”state，said Elias Towe，a professor of electrical and computer engineering at Carnegie Mellon University．
L．“Band-gap engineering has been and remains the biggest challenge in the development of graphene transistors and computer chips．”Lau said．It requires controlling the material almost down at the atomic level，and“that’s really pushing the edges of existing technology,”Patterson said．“In 10 years，we’11 start to see these problems solved．”
‘It is largely a matter of time’
M．If graphene is to succeed as a replacement for silicon，every unit of cost and performance will make a difference，Towe said．
N．“Silicon is hard to displace，with all the billions dollars of investments made in manufacturing infrastructure，”he said．“A replacement for silicon has to offer extraordinary performance at extremely rock-bottom cost to compel industry to change its way．”
O．Though graphene is just 10 years old—in contrast,use of silicon in transistors dates to the early 1950s—considerable progress has already been made．For example，the largest graphene sheet was produced by hand in a laboratory eight years ago；its width was less than that of a human hair．“Nowadays，roll-to-roll printing of graphene sheets up to 1 00 meters long has been achieved，”Lau said．“With the increasing interest，investment，and research in graphene-based technology,I think it is largely a matter of time before the economy of scale kicks in and truly low-cost，large-scale production ofhigh-quality graphene is accomplished，”she added．

The End of Food
Has a tech entrepreneur come up with a product to replace our meals?
A．In December of 2012，three young men were living in a claustrophobic(患幽閉恐懼癥的)apartment in San Francisco’s Tenderloin district，working on a technology startup．They had received a hundred and seventy thousand dollars from the incubator Y Combinator．but their project—a plan to make inexpensive cell-phone towers——had failed．Down to their last seventy thousand dollars．they resolved to keep trying out new software ideas until they ran out of money．But how to make the funds last?Rent was a sunk cost．Since they were working frantically,they already had no social life．As they examined their budget，one big problem remained：food．
B．They had been living mostly on ramen，com dogs，and Costco frozen quesadillas——supplemented by Vitamin C tablets，to stave of rescurvy(壞血病)——but the grocery bills were still adding up．Rob Rhinehart，one of the entrepreneurs，began to resent the fact that he had to eat at all．“Food was such a large burden，”he told me recently．“It was also the time and the hassle．We had a very small kitchen，and no dishwasher．”He tried out his own version of“Super Size Me．”living on McDonald’s dollar meals and five．dollar pizzas from Little Caesars．But after a week．he said,“I felt like l was going to die．”Kale was all the rage——and cheap——so next he tried an all．kale diet．But that did not work，either．“I was starving，”he said．
C．Rhinehart，who is twenty-five，studied electrical engineering at Georgia Tech，and he began to consider food as an engineering problem．“You need amino acids(氨基酸)and lipids，not milk itself,”he said．“You need carbohydrates(碳水化合物)，not bread．”Fruits and vegetables provide essential Vitamins and minerals．but they’re“mostly water．”He began to think that food was an inefficient way：of geRing what he needed to survive．“It just seemed like a system that’s too complex and too expensive and too fragile，”he told me．
D．What if he went straight to the law chemical components?He took a break from experimenting with software and studied textbooks on nutrifional biochemistry and the Web sites of the F.D．A．,the U．S．D．A．，and the Institute of Medicine．Eventually,Rhinehan compiled a list of thirty-five nutrients required for survival．Then，instead of heading to the grocery store，he ordered them ofr the Intemet--mostlyin powder or pill form——and poured everything into a blender'with some water．The result．a slurry of chemicals，looked like gooey lemonade．Then，he told me，“I started living on it．”
E.Rhinehart called his potion Soylent，which，for most people，evokes the 1973 science-fiction film“Soylent Green．”starring Charlton Heston．The movie is set in a dystopian future where，because ofoverpopulation and pollution，people live on mysterious wafers called Soylent Green．The film ends with the ghastly revelation that Soylent Green is made from human flesh．
F.Rhinehart’s roommates were skeptical．One told me，“It seemed pretty weird．”They kept shopping at Costco．After a month，Rhinehart published the results of his experiment in a blog post，titled“How I Stopped Eating Food．”The post has a“Eureka!”tone．The chemical potion，Rhinehart reported，was“delicious!I felt like l’d just had the best breakfast of my life．”Drinking Soylent was saving him time and money：his food costs had dropped from four hundred and seventy dollars a month to fifty．And physically,he wrote，“I feel like the six million dollar mail．My physique has noticeably improved，my skin is clearer,my teeth whiter,my hair thicker and my dandruff gone．”He concluded．“I haven’t eaten a bite of food in thirty days，and it's changed my lifc．”In a fcw weeks，his blog post was at the top of Hacker News——a water cooler for the tech industry．Reactions were polarized．“RIP Rob，”a comment on Rhinehart’s blog read．But other people asked for his formula，which，in the spirit of the“open source”movement，he posted online．
G.One of Silicon Valley’s cultural exports in the past ten years has been the concept of“life hacking”：devising tricks to streamline the obligations of daily life．thereby freeing yourself up for whatever you’d rather be doing．Rhinehart’s“future food”seemed a clever work．around．Lifehackers everywherebegan to test it out，and then to make their own versions．Soon commenters on Reddit were sparring about the appropriate dose of calcium-magnesium powder．Atier three months，Rhinehart said，he realized that his mixture had the makings of a company：“It provided more value to my life than any app．”He and his roommates put aside their software ideas．and got into the synthetic．food business．
H. To attract funding，Rhinehart and his roommates turned to the Internet：they set up a crowd-funding campaign in which people could receive a week’s supply of manufactured Soylent for sixty-five dollars．They started with a fund．raising goal of a hundred thousand dollars，which they hoped to raise in a month．But when they opened up to donations，Rhineha It says，“we got that in two hours．”Last week，the first thirty thousand units of commercially made Soylent were shipped out to customers across America．In addition to the crowd．funding money,its production was financed by Silicon Valley venture capitalists，including Y Combinator and the blue．chip investment firm Andreessen Horowitz， which contributed a million dollars．
I. Soylent has been heralded by the press as“the end of food，”which is a somewhat bleak prospect．It conjares up visions of a world devoid of pizza parlors and taco stands——our kitchens stocked with beige powder instead of banana bread，our spaghetti nights and ice-cream socials replaced by evenings sipping sludge．
J.But，Rhinehart says，that’s not exactly his vision．“Most of people’s meals are forgotten，”he told me．He imagines that，in the future，“we’ll see a separation between our meals for utility and function，and our meals for experience and socialization．”Soylent isn’t coming for our Sunday potlucks．It’s coming for our frozen quesadillas．

4、根據材料，回答題：
        The argument that global warming is causing more extreme weather is problematic because it presumes the globe is warming.  In fact, the global temperature trend line has been stable for more than a dozen years, while carbon dioxide has increased 7%. If carbon dioxide was the driver, then why have global temperatures stopped increasing?
        Keep in mind that carbon dioxide represents 0.0395% of the Earth's atmosphere. Arguing that carbon dioxide is driving the small temperature variations in our climate as opposed to the oceans, which cover70% of the planet and have 1,000 times the heat capacity of air, or the output of our sun, is scientifically disturbing.
        Weather is more publicized nowadays because of its impact on society and the constant push of the global warming agenda. Increases in population result in more people being in the path of Mother Nature's great anger. Global warming activists attribute every major weather event to man because they are either uninformed about history, or choose to ignore it. The latest claims resulting from this series of hot and dry summers ignore the fact that more state heat records were set in the 1930s than all other decades of the last century combined. Anyone remember the Dust Bowl?
Seven major hurricanes hit the East Coast from 1954 to 1960. Now that we are in a pattern similar to the 1950s, the East Coast is vulnerable once again, and attributing events like Hurricane Irene to global warming is incorrect. All the Intergovernmental Panel on Climate Change (IPCC．projections for our climate have proved to be wrong. Global temperatures have stopped increasing and are nowhere near estimates made a decade ago. The IPCC incorrectly predicted Arctic sea ice would disappear by now.
        After Katrina in 2005, more and stronger hurricanes were forecast to be the future. The Accumulated Cyclone Energy Index for the globe has instead declined to the lowest level in 30 years. This does not mean we will not see warm weather and land-falling hurricanes. We are in a pattern similar to the 1950s when U.S. heat and drought as well as East Coast land-failing hurricanes were quite prevalent.
        Perhaps when the Atlantic becomes cold, we will be hearing Ice Age scares again as we did in the 1970s.

According to the first, paragraph_______.
A．there is less extreme weather
B．the global temperature is always stable
C．the globe is not waring
D．carbon dioxide delays global wanning
