Hurricane（飓风）Katrina
A hurricane is a fiercely powerful , rotating（旋转的）form of tropical storm that can be 124 to 1,240 miles in diameter. The term hurricane is derived from Hurican,the name of a native American storm god.Hurricanes are typical of a calm central region of low pressure between 12 to 60 miles in diameter,known as the eye.They occur in tropical regions.Over its lifetime,one of these can release as much energy as 10,000 nuclear bombs.
The seed for hurricane formation is a cluster（聚集）of thunderstorm over warm tropical waters. Hurricanes can only form and be fed when the sea一surface temperature exceeds 27℃and the surrounding atmosphere is calm. These requirements are met between June and November in the northern part of the world.
Under these conditions, large quantities of water evaporate (蒸发）and condense（冷凝）into clouds and rain一releasing heat in the process.It is this heat energy,combined with the rotation of the Earth,that drives a hurricane.
When the warm column of air from the sea surface first begins to rise,it causes an area of low pressure.This in turn creates wind as air is drawn into the area. This spinning wind drags up more moist air from the sea surface in a process that strengthens the storm. Cold air falls back to the ocean surface through the eye and on the outside of the storm.
Initially,when wind speeds reach 23 miles per hour,these mild,wet and grey weather systems are known as depressions,or low air pressure.Hurricane Katrina formed in this way over the south-eastern Bahamas on 23 August 2005.Katrina has had a devastating impact on the Gulf Coast of the U.S.,leaving a disaster zone of 90,000 square miles in its wake（尾迹）—almost the size of the U.K.Thousands have been killed or injured and more than half a million people have become homeless in a humanitarian（人道主义的）crisis of a scale not seen in the U. S. since the Great Depression.The cost of the damage may top$100 billion.
Which of the following is NOT true of Hurricane Katrina according to the last paragraph?
A:The area affected is almost as big as the U.K.
B:It has left a disaster zone of 90,000 square miles.
C:Over half a million people have been forced to leave their homes.
D:This crisis is more serious than that of the Great Depression.

Why Would They Falsely Confess?
Why on earth would an innocent person falsely confess to committing a crime?To most
people,it just doesn't seem logical .But it is logical,say experts,if you understand what
can happen in a police interrogation（审讯）room.
Under the right conditions, people's minds are susceptible（易受影响的）to influence, and t
he pressure put on suspects during police grillings（盘问）is enormous.________(1)
"The pressure is important to understand,because otherwise it's impossible to understand why
someone would say he did something he didn't do.The answer is:to put an end to an
uncomfortable situation that will continue until he does confess."
Developmental psychologist Allison Redlich recently conducted a laboratory study to
determine how likely people are to confess to things they didn't do.________(2)The
researchers then intentionally crashed the computers and accused the participants of hitting
the"alt"key to see if they would sign a statement falsely taking responsibility.
Redlich's findings clearly demonstrate how easy it can be to get people to falsely
confess : 59 percent of the young adults in the experiment immediately comfessd.
__________ (3) Of the 15 to 16 year olds, 72 percent signed confessions ,as did 78
percent of the 1 2-to-1 3-year olds.
"There's no question that young people are more at risk, " says Saul Kassin, a
psychology professor at Williams College,who has done similar studies with similar results.
________(4)
Both Kassin and Redlich note that the entire"interrogation"in their experiments
consisted of a simple accusation一not hours of aggressive questioning一and still,most
participants falsely confessed.
Because of the stress of a police interrogation,they conclude,suspects can become
convinced that falsely confessing is the easiest way out of a bad situation.________(5)
_________（4）
A:In her experiment,participants were seated at computers and told not to hit the"alt" key,because doing so would crash the systems.
B:"In some ways,"says Kassin,"false confession becomes a rational decision."
C:" It's a little like somebody's working on them with a dental（牙齿的）drill," says Franklin Zimring,a law professor at the University of California at Berkeley.
D:"But adults are highly vulnerable too."
E:How could an innocent person admit to doing something he didn't do?
F:Redlich also found that the younger the participant,the more likely a false confession.

Lakes,Too,Feel Global Warming
There's no doubt:In the last few decades,the average temperature on Earth has been higher than it has
been in hundreds of years.Around the world,people are starting to measure the effects of global warming一
and trying to figure out what to do about it.
Scientists recently used satellites to study the temperatures of lakes around the world,and they found
that lakes are heating up.Between 1985 and 2009,satellites recorded the nighttime temperatures of the sur-
faces of 167 lakes.During those 24 years,the lakes got warmer by an average of about 0.045 degree
Celsius per year.
In some places,lakes have been warming by as much as 0.10 degree Celsius per year. At that rate,a
lake may warm by a full degree Celsius in just 10 years.That difference may seem small一you might not
even notice it in your bath.But in a lake,slightly warmer temperatures could mean more algae（水藻）,and
algae can make the lake poisonous to fish.
The study shows that in some regions,lakes are warming faster than the air around them.This is impor-
tant because scientists often use measurements of air temperature to study how Earth is warming. By using
lake temperatures as well,scientists can get a better picture of global warming. The scientists say data on
lakes give scientists a new way to measure the impact of climate change around the world.
That's going to be useful,since no country is too big or too small to ignore climate change.Scientists
aren't the only ones concerned.Everyone who lives on Earth is going to be affected by the rapid warming of
the planet. Many world leaders believe we might be able to do something about it,especially by reducing the
amount of greenhouse（温室）gases we put into the air.
That's why the United Nations started the Framework Convention on Climate Change,or UNFCCC.
Every year the convention meets,and representatives from countries around the world gather to talk about
climate change and discuss global solutions to the challenges of a warming world.
A slight temperature increase in a lake could be harmful to fish.
A:Right
B:Wrong

Technology Transfer in Germany
When it comes to translating basic research into industrial success,few nations can
match Germany.Since the 1940s,the nation's vast industrial base has been fed with a
constant stream of new ideas and expertise from science.And though German prosperity
（繁荣）has faltered（衰退）over the past decade because of the huge cost of unifying east
and west as well as the global economic decline , it still has an enviable（令人羡慕的)
record for turning ideas into profit.
Much of the reason for that success is the Fraunhofer Society,a network of research
institutes that exists solely to solve industrial problems and create sought-after technologies.
But today the Fraunhofer institutes have competition.Universities are taking an ever larger r
ole in technology transfer,and technology parks are springing up all over.These efforts
are being complemented by the federal programmes for pumping money into start-up companies,
Such a strategy may sound like a recipe for economic success,but it is not without its
critics.These people worry that favouring applied research will mean neglecting basic
science,eventually starving industry of fresh ideas.If every scientist starts thinking like an
entrepreneur（企业家）,the argument goes , then the traditional principles of university
research being curiosity-driven,free and widely available will suffer.Others claim that
many of the programmes to promote technology transfer are a waste of money because half
the small businesses that are promoted are bound to go bankrupt within a few years.
While this debate continues,new ideas flow at a steady rate from Germany's research
networks,which bear famous names such as Helmholtz,Max Planck and Leibniz.Yet it is the
fourth network,the Fraunhofer Society,that plays the greatest role in technology transfer.
Founded in 1949,the Fraunhofer Society is now Europe's largest organisation for
applied technology,and has 59 institutes employing 12,000 people.It continues to grow.
Last year,it swallowed up the Heinrich Hertz Institute for Communication Technology in
Berlin.Today,there are even Fraunhofers in the U.S. and Asia.
What factor can be attributed to German prosperity?
A:Technology transfer.
B:Good management.
C:Hard work.
D:Fierce competition.

The Smog（烟雾）
For over a month,Indonesia was in crisis.Forest fires raged out of control as the
country suffered its worst drought for 50 years.Smoke from the fires mixed with sunlight and
hot dry air to form a cloud of smog.This pollution quickly spread and within days it was
hanging over neighbouring countries including Malaysia,Singapore and Thailand.
When the smoke combined with pollution from factories and cars,it soon became
poisonous（有毒的）.Dangerous amounts of CO became trapped under the smog and
pollution levels rose. People wheezed（喘息）and coughed as they left the house and their
eyes watered immediately.
The smog made it impossible to see across streets and whole cities disappeared as
grey soot（烟灰） covered everything. In some areas, water was hosed（用胶管浇）from
high-rise city buildings to try and break up the smog.
Finally,heavy rains,which came in November,put out the fires and cleared the air.
But the environmental costs and health problems will remain.Many people from South-
Eastern Asian cities already suffer from breathing huge amounts of car exhaust fumes（汽车
排放的废气）and factory pollution. Breathing problems could well increase and many non-
sufferers may have difficulties for the first time.Wildlife has suffered too.In lowland
forests,elephants,deer,and tigers have been driven out of their homes by smog.
But smog is not just an Asian problem.In fact,the word was first used in London in
1 905 to describe the mixture of smoke and thick fog.Fog often hung over the capital.
Sometimes the smog was so thick and poisonous that people were killed by breathing
problems or in accidents.About 4, 000 Londoners died within five days as a result of thick
smog in 1952.
The smog spread to neighbouring countries.

After months of eager anticipation,the day finally_______(54).You pack your bags and _______(55)you go.Several hours later,the plane lands.The_______(56)comes in and says,"Welcome to Holland."

Compact Disks
If someone says to you your music CDs don't really hold any music on them,and they only have numbers recorded on them,you may not believe it.In fact,he is right in that sound is actually recorded onto the CDs as special numbers-a digital code.The code is pressed onto the CD as bumps（隆起）on a long spiral track almost five kilometers long.These bumps are an average of 0.5 microns（微米）wide.
A small laser beam shines onto the bumps as the CD turns.The light is reflected back to a receiver that records how the laser light bounces back.This lets the CD player turn the reflected light back into the original code.This means you can hear the original code as music.
Digital codes are used with many technologies.E-mail needs these kinds of code numbers.Space probes （探测仪）communicate with their ground station on earth using digital codes.Bar codes are read as digital codes in computer systems.Digital communications with cell phones need digital codes.Weather radios also tune in to specific signals using these codes.
There are many types of compact disks.One format is called CD-RWs.They can be recorded on and re-recorded on(rewritten on)as you would do with a floppy disk（软盘）.Another format is the CD-ROM.The technology for recording on these disks is different from other CDs.These CDs have a dye layer that the CD writer can darken or leave clear.The clear and dark spots are the digital code.CD-ROM stands for Compact Disc-Read Only Memory.This disk is like a"super" floppy disk that can hold lots of information.One CD-ROM can hold the same amount of data as 500 floppy disks.Information is permanently recorded onto it.Computer games and other programs are considered to be CD-ROMs.
CDs were first sold to the public in 1982.These CDs still play well and sound fine.Current CDs are expected to last between 70 to 200 years.Of course,you can make sure your CDs last a long time by taking care of them.
Science keeps on developing.It may not be many more years before a completely new technology is invented and introduced to the public for music recording.In the meantime,there is no doubt you will continue to enjoy listening to your favorite music on CDs and play your favorite computer games on CD-ROMs.
CDs can last a long time if______.
A:they are seldom used
B:they play well and sound fine
C:their users take good care of them
D:they are developed with new technology
