7.Clean your ears,because airport security might soon be scanning them.According to a recent discovery,the shape of ears could provide a reliable new way of identifying people at airports.
Researchers discovered that ears of each person have a unique shape and they have created a system that can scan them.The ear scanning technique uses a technology called image ray transform that highlights all the tubular structures (结构) of the ear and measures them.Professor Mark Nixon,a computer scientist who led the team from the University of Southampton,believes ear scanning could take place as passengers walk through security gates,for example,by placing cameras on either side to record an image of their ears.Comparing the results against a database of ear shapes,the new system could help airport security workers instantly identify passengers.
Nixon and his team tested 252 images of different ears and found the system was able to match each ear to a separate image held in its database with 99 percent accuracy.
Besides ear scanning,there have been other systems developed for identity recognition.
"With facial recognition,the systems are often confused by crows feet (鱼尾纹) and other signs of ageing,"Nixon said."Your ears,however,age very gracefully.They grow proportionally (按比例) and your lobe (耳垂) gets a bit larger,but otherwise your ears are fully formed from birth."What's more,facial recognition software is often confused by changes in expression so people need to control their faces and in some cases even avoid wearing make-up.
An ear scan system would also offer a less invasive alternative to retina (视网膜) scanning,which requires passengers to stare at scanners from a close range.
Fingertip detection has long been the most effective way of identifying someone.Nixon expects there to be a combination of different techniques that can be used at the same time to identify a person."
56.The ear scanning system would help to find outC
A.where you come from                          
B.whether you are healthy
C.who you are                                                       
D.who shares your ear shape
57.The article does not sayD.
A.who developed the system                            
B.how the system works
C.where the system can be applied                
D.how long the system took to develop
58.Ear scanning would work better than facial recognition mainly becauseB
A.the ear scanning system is computerized 
B.ears change less with age than faces
C.facial expressions are often the same                 
D.facial appearances aren't unique
59.The underlined word"invasive"in the last but one paragraph possibly means"D".
A.comfortable          
B.expensive                 
C.disappointing                 
D.annoying
60.Nixon has developed the ear scanning system while there's already the fingertip detection becauseC.
A.ear scanning can be used at airports                  
B.fingertip detection is not so convenient
C.he doesn't think one system is enough      
D.ear shapes are easier to read than fingerprints.

15.Everyone needs a break,and vacations are not meant for serious study.(36)FThe Spring Festival is coming up so this is the perfect time to discuss some great English language literature to take on a long train journey.
Before getting into the recommendations,you need to determine your English reading comprehension level.If you're at the beginner level,there are two options:reading a children's book or reading a book that you've read in Chinese translation.(37)GIf you're at the intermediate level,popular books like pop fiction,mysteries and thrillers are good options.For advanced readers,classic works of literature or modern prize winners (Nobel,Pulitzer) are good options.
(38)BWhen I pick up a book I like,even though the first few chapters are really hard to get through,I would try to get accustomed to the language the author uses.Generally,after the first few chapters,things get a lot easier,especially if I get involved in the story.
Another great way to keep yourself motivated is to find a friend who's interested in reading the same book.You can make goals that you both want to achieve.(39)E  Some quick recommendations:Harry Potter,start with the first book and go on from there; the Narnia series; anything by US writer Michael Crichton; and if you like horror,US writer Stephen King is always unusual and fun.(40)DHappy reading!

2.An Australian man who has been donating his extremely rare kind of blood for 56years has saved the lives of more than two million babies.
James Harrison has an antibody in his plasma that stops babies dying from Rhesus disease,a form of severe anaemia.He has enabled countless mothers to give birth to healthy babies,including his own daughter,Tracey,who had a healthy son thanks to her father's blood.
Mr.Harrison has been giving blood every few weeks since he was 18years old and has now racked up a total of 984donations.When he started donating,his blood was deemed so special that his life was insured for one million Australian dollars.
He was also nicknamed the"man with the golden arm"or the"man in  two million".He said:"I've never thought about stopping.Never."He made a pledge to be a donor aged 14after undergoing major chest surgery in which he needed 13litres of blood."I was in hospital for three months,"he said."The blood I received saved my life so I made a pledge to give blood when I was 18."
Just after he started donating he was found to have the rare and life-saving antibody in his blood.At the time,thousands of babies in Australia were dying each year of Rhesus disease.Other newborns suffered permanent brain damage because of the condition.The disease creates an incompatibility between the mother's blood and her unborn baby's blood.It stems from one having Rh-positive blood and the other Rh-negative.
His blood has since led to the development of a vaccine called Anti-D.After his blood type was discovered,Mr.Harrison volunteered to undergo a series of tests to help develop the Anti-D vaccine."They insured me for a million dollars so I knew my wife Barbara would be taken care of,"he said."I wasn't scared.I was glad to help.I had to sign every form going and basically sign my life away."
Mr.Harrison is Rh-negative and was given injections of Rh-positive blood.It was found his plasma could treat the condition and since then it has been given to hundreds of thousands of women.It has also been given to babies after they are born to stop them developing the disease.
It is estimated he has helped save 2.2million babies so far.Mr.Harrison is still donating every few weeks now.

12.In its first ever National Building Competition,the U.S.Environmental Protection Agency (EPA) challenged the teams from across the nation to cut wasteful energy use in buildings where they live and work.Family and commercial ladings together consume 40 percent of U.S.energy and the Obama Administration is eager to show how that load can be reduced.
In recent remarks at a university.President Barack Obama promoted a plan that could help commercial buildings achieve greater energy efficiency (效率).
"Making our buildings more energy-efficient is one of the fastest,easiest and cheapest ways to save money,fight against pollution and create jobs right here in the United States of America,"he said.He also inspected the research labs where scientists are working on new technologies designed to cut energy waste in commercial buildings.
Stores like the Sears department store in Maryland,which took second prize in the contest,are already using some of those technologies.As part of the store's bid to cut its energy use,every one of the building's 24 rooftop AC (交流电) units was checked and repaired.Every light bulb-all 15,000 of them-was replaced with a more efficient one.And sensors were installed (安装)to shut lights off in offices and storerooms when no one is around.Taken together these changes helped the Sears store reduce its building energy consumption by more than one-third and cut electric bills by $ 46,000.
Office buildings can also achieve impressive energy savings.The tenants of a 12-story building in Virginia managed to cut the building's energy consumption by 28 percent as part of the EPA competition.
"Whether it's an office building or a department store,a school or church,the EPA energy challenge showed that there's always room for improvement",says Jennifer Amann with the American Council for an Energy Efficient Economy,

73.The Sears department storeA
A.used new technologies to cut its energy waste
B.won the first prize in the Competition
C.cut its energy consumption by 28 percent
D.had 24 rooftop sensors installed on the building
74.The 12-story building in Virginia mentioned in the text should be a(nC
A.department store                                        
B.commercial building
C.office building                        
D.family building
75.From what Jennifer Amann says,we can infer thatC   
A.the awareness of energy efficiency has highly improved
B.energy savings will benefit the whole world
C.all buildings can be energy-efficient if changes are made
D.the government is responsible for energy waste.

19.Are you working on your typing skills to make you become a more efficient worker?That may be all for nothing as Intel believes that we will be able to manage our computers with our brains by 2020.
Intel and its research partners are studying how the brain acts when it thinks.For example,scientists have found that people's brains react in a similar way when they are asked to think of a bear.Through some equipment that can also find this sort of brain activity,Intel thinks that it will be able to read and translate this into an input system tanks to an implantable chip in the brain.
"We are trying to prove you can do interesting things with brain waves."Intel research scientist Dean Pomerleau told Computerworld."Eventually people may be willing to be more devoted to brain implants."Even if thinking about a bear isn't enough to show that you want to copy something,Intel still thinks that there is a future in suing your brain instead of the keyboard."If we can get to the point where we can find specific words,you could mentally type,"he added."You could compose characters or words by thinking about letters flashing on the screen."
While this may all sound impractical or even inconvenient for present time,Intel thinks that it's possible.
"I think human beings are very adaptive,"said Andrew Chien,vice president of research and director of future technologies research at the Intel Labs."If you had told people 20years ago that they would be carrying computers all the time,they would have said,‘I don't want that.'Now you can't get them to stop.There are a lot of things that have to be done first but I think implanting chips into human brains is possible."
Make good use of your mouse and keyboard set-up before they're old-fashioned.

64.What can be known about Intel from the passage?D
A.it is researching how our brains manage our computers.
B.it is working on how to improve people's typing skills.
C.It is finding how the brain reacts when it thinks of a bear.
D.It is studying the relation between what the brain thinks and how it acts.
65.From what Dean Pomerleau said,we can learn thatC.
A.brain implants are not accepted now
B.people have no interest in the research
C.mentally typing will probably be a real fact
D.new things need a long time to be accepted
66.What Andrew Chien said can prove thatD.
A.everything is possible in the world
B.man has great power to face difficulties
C.society is changing from time to time
D.man is very good at accepting new things
67.What does the last paragraph implay?B
A.Everything should be used to the full.
B.Mouses and keyboards won't exist in the future.
C.Our brains can take the place of computers.
D.Some new kinds of mouse and keyboard will appear.
