Directions:In this section,you are going to read a passage with ten statements attached to it.Each statement contains information given in one of the paragraphs.Identify the paragraph from which the information is derived.You may choose a paragraph more than once.Each paragraph is marked with a letter.Answer the questions by marking the corresponding letter on Answer Sheet 2.
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(光电检测器),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(��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�)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.

Nanoplatelet is the powder-or flake-type of graphene that has been used for some time to make conductors and that is being launched on the market.


3�Questions are based oB thefollowingpassage.
The unemployment rate continues to improve.It was 10%in the fall of 2009.It was 7.5%at this time last year.It has been fluctuatin9 6.3%and 6.7%for the last couple months.
But before we celebrate.we need to examine the numbers behind the numbers.These can mask deeper problems.
Youth unemployment.is one such problem.Young people face higher hurdles to and in the job market.
They have fewer skills.1ess work experience and smaller networks.
The consequences are devastating and the facts bear this out.
Those with more education do beaer but no group is held harmless.Unemployment rates for recent college graduates increased from 3.1%in 2008 to 8%in 2010.High youth unemployment rates predate the recession.In 2000.the general unemployment rate was approximately 4%.For 15 to 24 year olds it was over9%.
High youth unemployment is not confined to the United States.For the 33“developed�countries in the Organization for Economic Co-operation and Development(OECD),combined 2013 youth unemployment was 16%.But more importantly,individuals,society and the economy suffer from a generation hamstrung by pool little or no work experience.
Solutions are complicated because we are part of a global economy and recession,we are shifting to a knowledge-based economy,and unemployment is tied to complex social problems.
But solutions do exist.
Create a“youth guarantee�similar to the one adopted by leaders of the European Union.It states that“all young people under the age of 25 years receive a good-quality offer of employment,continued education,an apprenticeship or a traineeship within four months of becoming unemfDloyed or leaving
formal education.�This has had success in some countries.
Require that middle and high school programs greatly strengthen their workplace ties through vocational education,apprenticeships,internships,and teaching ofjob skills.
As the economic recovery continues,we must ensure that we understand the numbers behind the numbers.This means not only paying close attention to the needs of our young workers but also responding with significant and decisive action.
The United States has a population of over 300 million.of these.120 million are under the age of 30.Their future is Our future.

What Can we infer from the lines of paragraph two?
A.The reA.problem of youth unemployment is still severe.
B.We can not only concentrate on the surface of numbers.
C.The unemployment rate continues to be improveD.
D.We should not celebrate for the lower unemployment rate.
