13.Want a glance of the future of health care?Take a look at the way the various networks of people about patient care are being connected to one another,and how this new connectivity is being exploited to deliver medicine to the patient-no matter where he or she may be.
Online doctors offering advice based on normal symptoms(癥狀) are the most obvious example.Increasingly,however,remote diagnosis(遠程診斷) will be based on real physiological data(生理數(shù)據(jù)) from the actual patient.A group from the University of Kentucky has shown that by using personal data assistance plus a mobile phone,it is perfectly practical to send a patient's important signs over the telephone.With this kind of equipment,the cry asking whether there was a doctor in the house could well be a thing of the past.
Other medical technology groups are working on applying telemedicine to rural(countryside) care.And at least one team wants to use telemedicine as a tool for disaster need-especially after earthquakes.On the whole,the trend is towards providing global access to medical data and experts'opinions.
But there is one problem.Bandwidth(寬帶) is the limiting factor for sending complex(復(fù)雜的) medical pictures around the world-CT photos being one of the biggest bandwidth users.Communication satellites may be able to deal with the short-term needs during disasters such as earthquakes or wars.But medicine is looking towards both the second-generation Internet and third-generation mobile phones for the future of remote medical service.
Doctors have met to discuss computer-based tools for medical diagnosis,training and telemedicine.With the falling price of broadband communications,the new technologies should start a new time when telemedicine and the sharing of medical information,experts'opinions and diagnosis are common.
59.The writer chiefly talks aboutA
A.the use of telemedicine                 
B.the on-lined doctors
C.medical care and treatment        
D.communication improvement
60.The basis of remote diagnosis will beC.
A.personal data assistance 
B.some words of a patient
C.real physiological information
D.medical pictures from the Internet
61.Which of the following statements is true according to the text?D
A.Patients don't need doctors in hospitals any more.
B.It is impossible to send a patient's signs over the telephone.
C.Many teams use telemedicine dealing with disasters now.
D.Broadband communications will become cheaper in the future.
62.The"problem"in the fourth paragraph refers to the fact thatA.
A.bandwidth isn't big enough to send complex medical pictures
B.the second-generation of Internet has not become popular yet
C.communication satellites can only deal with short-term needs
D.there is not enough equipment for spreading the medical care.

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 (交流電) units was checked and repaired.Every light bulb-all 15,000 of them-was replaced with a more efficient one.And sensors were installed (安裝)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,
71.The purpose of the Competition is toA
A.help cut buildings'energy waste                        
B.fight against air pollution
C.create more job opportunities                           
D.experiment with a new idea
72.Which of the following is true according to the text?B
A.Forty percent of the U.S.energy is wasted.
B.Scientists are developing new technologies for energy efficiency.
C.Efficient bulbs are now being used in all American buildings.
D.Family buildings consume more energy than commercial ones.
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.a(chǎn)ll buildings can be energy-efficient if changes are made
D.the government is responsible for energy waste.

11.Areas of Tokyo which had usually been packed with office workers like sushi(壽司) restaurants and noodle shops were unusually quiet.Many schools were closed.Companies allowed workers to stay home.Long queues formed at airports.
As Japanese authorities struggled to avoid disaster at an earthquake-battered nuclear plant 240 km to the north,parts of Tokyo resembled a ghost town.Many people stocked up on food and stayed indoors or simply left.transforming one of the world's biggest and most populated cities into a shell of its usual self.
"Look,it's like Sunday-no cars in town,"said Kazushi Arisawa,a 62-year-old taxi driver,as he waited for more than an hour outside an office tower where he usually finds customers within minutes."I can't make money today."
Radiation in Tokyo has been negligible, briefly touching three times the normal rate on Tuesday,smaller than a dental X-ray.On Wednesday,winds over the Fukushima (福島) nuclear-power plant blew out to sea,keeping levels close to normal.But that does little to relieve public anxiety about a 40-year-old nuclear plant with three reactors in partial meltdown (熔毀)and a fourth with spent atomic fuel exposed to the atmosphere after last Friday's earthquake and tsunami.
"Radiation moves faster than we do,"said Steven Swanson,a 43-year-old American who moved to Tokyo in December with his Japanese wife to help with her family business.He is staying indoor but is tempted to leave."It's scary.It's a triple threat with the earthquake,tsunami and the nuclear radiation leaks.It makes you wonder what's next."
56.The text is mainly aboutC   
A.the earthquake that happened in March
B.the government's effort to avoid disaster
C.the effects of the nuclear radiation leaks
D.the earthquake-battered nuclear-power plant
57.What did Kazushi Arisawa mean?D
A.There're usually more cars on Sundays.
B.He didn't care much about nuclear radiation.
C.He preferred to stay at home on Sundays.
D.He couldn't find many customers.
58.The underlined word"negligible"in Paragraph 4 most probably meansB.
A.serious          B.slight           C.normal          D.a(chǎn)verage
59.What can we learn about the Fukushima nuclear-power plant from the text?C
A.It lies to the south of Tokyo.
B.It started to operate about fifty years ago.
C.It was damaged in the earthquake and tsunami.
D.All its four reactors are now well under control
60.Which of the following is true of Steven Swanson?A
A.He moved to Japan with his wife last year.
B.He is now on way back to the United States.
C.He wanted to stay on to see what's next.

10.We have seen that pesticides(殺蟲劑) now pollute soil,water and food,and that they have the power to make our rivers fishless and our gardens and woodlands silent and birdless.Man,however much he may like to pretend the opposite,is part of nature.Can he escape a pollution that is now so thoroughly spread throughout our world?
We know that even single exposure to these chemicals,if the amount is large enough,can cause extremely severe poisoning.But this is not the major problem.The sudden illness or death of farmers,farm workers and others exposed to enough quantities of pesticides is very sad and should not happen.For the population as a whole,we must pay more attention to the delayed effects of taking in small amounts of the pesticides that unseeably pollute our world.
Responsible public health officials have pointed out that the biological effects of chemicals are increasing in amount over long periods of time,and that the danger to the man may depend on the amount of the exposures received throughout his lifetime.For these very reasons people easily take no notice of the danger.It is human nature to shake off what may seem to us a future disaster."Men are naturally most impressed by diseases which have obvious signs,"says a wise physician,Dr.Rene Dubos,"yet some of their worst enemies slowly come near them unnoticed."

62.Which of the following can best summarize the first paragraph of this passage?_C
A.Man has a responsibility to bear for what has happened to nature.
B.Possibly man will escape the effects of environmental pollution.
C.Pesticide-caused pollution may also kill people.
D.Man acts as if he did not belong to nature.
63.People do not give enough attention to the delayed effects of exposure to chemicals becauseD.
A.imited exposure to them does little harm to people's health
B.the present is more important to them than the future
C.humans are able to bear small amounts of poisoning
D.the danger does not become seen clearly and immediately
64.Which of the following statements is true according to the passage?_A
A.A person exposed to pesticides even once may get seriously poisoned.
B.Birds are less sensitive to pesticides than humans.
C.The effects of pesticides on humans do not last as long as on fish.
D.Taking in small amounts of pesticides will not cause serious results.
65.We can conclude from what Dr Dubos says thatB.
A.people usually find hidden diseases difficult to deal with
B.people fail to notice hidden dangers caused by pesticides
C.diseases with obvious signs are mostly easy to cure
D.a(chǎn)ttacks by hidden enemies are likely to be deadly.

Yes.It should be banned.Smoking is not only bad for the smoker's health,but also for nonsmokers through passive smoking.In public people should think about others.
Alex Wright,23
Teacher (American nonsmoker)
I don't smoke.However,I don't really care if people smoke around me.Leave them alone. They have the right,and let them be.
Masako Imai,24
Phone engineer (Japanese smoker)
I smoke but I think it should be banned,I really want to give up and I think that if everywhere became nonsmoking,it would make it much easier for me to do so.
Luke Collings,35
Musician (British smoker)
I'm a smoker but am against others having to share my addiction.It's only a matter of time before society wakes up and realizes how addictive and destructive nicotine is.
Jenny Wilcox,31
Civil servant (British smoker)
I smoke but I agree with a ban.It forces people,including me,to smoke less.I'm from London,and although smokers were against the ban at first,it now feels totally normal.
Chris Kennedy,23
Student (British nonsmoker)

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 (結(jié)構(gòu)) 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 (魚尾紋) 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 (視網(wǎng)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.a(chǎn)nnoying
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.

6.A dog can be a source of help,as well as comfort,to someone who is disabled.Properly trained,a dog will pick up dropped items,help with dressing,turn on lights,activate an alarm and perform other tasks that allow disabled people to be independent.With a dog as a companion-and in need of a walk-a person who might otherwise stay alone at home can gain the confidence to go out and socialize.
Founded 22 years ago by Frances Hay,who had lost a leg to bone cancer,Dogs for the Disabled has redrawn the boundaries (界線) of who can be helped by dogs,and how.Other charities that train dogs focus on adult partnerships but,since 2004,Dogs for the Disabled has been helping under-18s.Starting with physically disabled children,dogs trained by the charity have given young people so much practical support that some are attending college.
Sam,a nine year-old with muscular dystrophy(肌肉萎縮癥),used to long for a friend who would never leave him or tell him he couldn't play."Sam's frustration filled every part of his life,"his mother,Sara,remembers."He stopped going out-even into the garden."In May 2009,Sam was partnered with a two-year-old dog,Josie,who helps him with everything from tidying his room to putting on splints (夾板).At night,she sleeps next to him and warns his parents if he is sick."Things were rubbish until she came to love me,"says Sam.
The assistance dogs have proved so successful that the charity cannot keep pace with demand.In an improved kennels (狗舍) near Banbury,a maximum of 30 dogs are trained at any one time,at a cost of?11,000 each.To date,the charity has created 450 dog-human partnerships of which 240 are currently active.
 
66.A trained dog can help the disabled with the following things exceptC
A.a(chǎn)ccompanying them to walk out             B.picking up dropped things
C.discouraging them from independence     D.a(chǎn)ssisting them with dressing
67.What can we learn about Dogs for the Disabled?D
A.It was founded to help people suffering from bone cancer
B.It focuses on helping disabled people to attend college.
C.It doesn't intend to train dogs to help the disabled over-18s.
D.It contributes much to physically disabled children.
68.We can learn from the text thatB.
A.Sam had not a single friend in the past
B.Josie rid Sam of his depression and changed his life
C.Sam used to go out to relax for pleasure frequently
D.Josie can predict when Sam is ill and warns his parents
69.The underlined word"frustration"in Paragraph 3 roughly meansC
A.great pleasure     B.self confidence       C.low spirits       D.strong will
70.The last paragraph suggests thatA.

5.It's often said that the eye is the window to the soul.But in this case,the eye is the window to Windows.At least,that was the goal when EyeTech Digital Systems got the help of some BYU engineering students in creating an all-in-one eye-tracking system.
The idea behind the project was to create an inexpensive computer system that could be controlled completely with a person's eyes.The hope was that this system could be used by people  with disabilities in parts of the world where they can't afford expensive eye-tracking systems.The students created the tablet(書寫板)for their yearlong engineering project for their customer,EyeTech Digital Systems,an Arizona-based company that designs and develops eye-tracking software.
A separate BYU engineering team also worked with EyeTech last year to develop and improve the initial eye-tracking tephnology,but this year's focus was to put the eye tracking into a housing similar to a thick PC.The finished product runs Windows 7 and has the eye-tracking system built in.After a quick adjustment,the system can move the mouse to wherever the user is currently looking.All it takes is a blink(眨眼)to click.
Systems with similar abilities can cost upwards of 14,000.Butthestudentswereabletofindcheaper,readilyavailableparts,pushingthecostdowntounder1,500.Jedediah Nieveen,the captain for this year's team,said the project was a challenge,but one that was rewarding on many levels."A lot of times in school you just work problems out of books,"he said."But this allowed us to take what we learned and apply it to something in real life,something that can help a lot of people,and that's really helped me."
Although the primary purpose of the product is to help people with disabilities,the technology could also have broader applications in the fields of research,advertising and even gaming.
71.According to the text,the eye-tracking system isB   
A.a(chǎn) high-tech computer                                    
B.a(chǎn) computer system operated by eyes
C.a(chǎn) way of protecting eyes                                
D.a(chǎn) software against information theft
72.How long will the research of the eye-tracking project last in all?A
A.About two years.                   
B.Just one year.
C.Over three years.                  
D.Less than one year.
73.The eye-tracking system was created toC   
A.help the poor students                                  
B.improve the computer system
C.support the disabled people                             
D.help to cure people's disabilities
74.What did the BYU engineering students value most during the project?B
A.Earning money for their education.
B.Putting their theory into practice.
C.Showing their talents in technology.
D.Increasing their job opportunities.
75.What can be inferred about the future of the eye-tracking system?A
A.It may face a promising market.
B.It is welcome only to the disabled people.
C.It'll change the disabled people's social position.

To feed so many people may require expanding farmland at the expense of forests and wilderness,or finding ways to completely increase crop output.
Gertjan Meeuws has taken the concept of a greenhouse a step further,growing vegetables and house plants in enclosed(封閉的)and regulated environments.In their research station,water flows into the pans when needed,and the temperature is kept constant.Lights go on and off,creating similar day and night,but according to the rhythm of the plant.
A building of 100 square meters and layers(層)of plants could provide a daily diet of 200 grams of fresh fruit and vegetables to the entire population of Den Bosch,about 140,000 people.Their idea isn't to grow foods that require much space,like corn or potatoes.
Here sunlight is not only unnecessary but can be harmful.Plants need only specific wavelengths of light to grow.Their growth rate is three times faster than under greenhouse conditions.They use about 90 percent less water than outdoors agriculture.And city fanning means producing food near the consumer,and there's no need to transport it long distances.
