6.Have you ever had such experience?Travelers in the airport line up and march slowly toward the full-body scanner(掃描儀).Have you wondered that screening may one day speed up dramatically?Now,scientists are creating a cheap and smart new device that gathers data in a flash.
It relies on microwaves to image objects.Microwaves are a form of electromagnetic radiation(電磁輻射)-types of energy that travel through space as a wave.Electromagnetic radiation includes visible (可見的) light,which can be seen with the naked eye.It also includes several types of energy,such as microwaves,that aren't visible with the naked eye.
In January,scientists at Duke University and elsewhere reported creating a new device that could help make smarter,faster and cheaper scanning machines.So far,the new device has been tested only in the lab.But if it works outside the lab,too,it could find use in a host of new products.
At airports,the new device could be used in machines that scan people for guns,knives or other would-be weapons.A technique similar to the one used by the researchers could be applied to other scanners,like those doctors use to peer into the body.This could reduce the amount of time patients spend in a scanner and the cost of such procedures.The device's designers even imagine police officers wearing vests embedded with the new technology to help identify a hidden weapon.
Instead of requiring expensive technology,a scanner based on the device could use existing materials (like copper) in a smarter way.Called metamaterials,these become useful based on how they're designed,not what they're made of.
"This definitely represents a less expensive and potentially faster alternative to current imaging methods,and its working principle is easily understood,"Kevin Kelly told Science News.Kelly is a technology specialist at Rice University in Houston.

67.What can we infer from the first paragraph?D.
A.Every traveler is willing to have a security scan.
B.The speed of security scan is slow because of so many travelers.
C.The new system has been put into market.
D.The current security scan system should be improved.
68.What is special about microwaves compared to visible light according to the passage?B.
A.It is a form of electromagnetic radiation.
B.You can't see it with your naked eyes.
C.It can travel through space.
D.It is a kind of energy.
69.With the new device we could do the following things exceptC.
A.shortening the patients'test time
B.helping patients spend less money
C.erasing the suffering of the patient
D.helping to identify a hidden weapon
70.What do you think the author will probably talk about in the following paragraph?A.
A.How does the new device work?
B.What is the new device like?
C.The application of the new device.
D.People's attitude about the new device.

18.While many probably remember using their childhood imaginations to turn the Moon's dark markings into a picture of a rabbit on the Moon,just recently China put a different sort of rabbit on the Moon:a lunar probe dubbed"Jade Rabbit."Now,they have followed up by releasing pictures of the probe in action.
Last weekend,China's National Space Administration made China the first nation to make a soft landing on the Moon since 37 years ago.The Soviet Union's probe,Luna 2,was the first on September 14,1959,followed by the United States,who eventually caught up with and surpassed the Soviet Union by putting the first human on the Moon,Neil Armstrong,on July 20,1969.
Jade Rabbit was launched on December 1 with the mission of exploring the Moon's surface in an attempt to locate natural resources.It will be deployed on this mission for a period of three months.
The probe reportedly shut down its explorations on December 16 due to high temperatures with plans to leave it inactive until December 23,but it was started up again on December 20 in order to gain more research time.
The country has aspirations of putting a human on the Moon by 2025,an area which has up until now been dominated by the United States,who last landed a man on the Moon in 1972 with astronaut Eugene Cernan.
China's recent attention to the Moon appears to have once again stirred up American interest in space exploration.In the December issue of New Space magazine,Christopher McKay makes an argument that the U.S.should consider setting up a lunar research base,citing among his reasons the fact that it is important to maintain U.S.influence on the Moon.
63.When did the humans make a soft landing on the moon next to China's?A
A.1976.B.1972.C.1969.D.1959.
64.The mission of the lunar probe will endB?
A.a(chǎn)fter 37 years exploration
B.a(chǎn)fter three months research.
C.till 2025
D.till 2017.
65.Which of the following statements is NOT TRUE?B
A.China will put a human on the Moon twelve years later.
B.Two countries have put humans on the moon-The USA and the former USSR.
C.Christopher McKay stated that the USA is interested in returning to the moon.
D.The probe shut down its explorations because it is extremely hot on the moon.
66.What does the underlined word mean in the first paragraph?B
A.Launched
B.Named
C.Made
D.Explored.

19.My mother finds more achievable with children as a school dinner lady rather than operating computers but some decades ago my mother was replaced by a computer.Her job was pressing buttons on an electromechanical adding machine to work out electricity bills.
In my generation I am faced with just how far this growth of technology will go in replacing not just jobs but more fundamental aspects of being human.
A Deloitte report published today suggests that 60% of jobs here in the North East are at high risk of being replaced by robots and artificial intelligence.Yet the implications(含義) are complex.Brynjolfsson and McAfee in The Second Machine Age argue that while some jobs will disappear,others will be created and some existing jobs will become more valuable.This situation is extremely important for education,training and financial field.
But are there wider implications for spirituality?Will these intelligent machines become conscious and what might this mean for our self-understanding of what it means to be human?
Here we need to be careful in dealing with the complex relationship of science and science fiction.Humans and Alex Garland's Ex Machina present an almost inevitable appearance of intelligent machines with consciousness.However,the science is still uncertain about this possibility of intelligent machines,even if the fiction raises useful questions.Equally,those who directly rule it out by claiming that human beings will always be unique need to take scientific advances seriously.
As for me,I welcome intelligent machines taking away dull work,but also want to engage in the discussion of how we structure our world so that all can experience what it means to be fully human.And if the intelligent machines eventually appear as self-aware and with a capacity to love,then why should they not be loved by God?

32.Faced with the intelligent machines,the author's mother feelsA.
A.more comfortable as a dinner cook       
B.a(chǎn)imless for the future life
C.satisfied with the current situation      
D.hopeless with intelligent machines
33.According to Brynjolfsson and McAfee,what kind of job will still exist?D
A.Farmer.
B.News presenter.
C.Security guard.
D.Accountant.
34.What does the underlined word"it"refer to in the fifth paragraph?B
A.The science of intelligent machines.
B.Intelligent machines with consciousness.
C.The science fiction involved useful questions.

11.That woman carried a new blanket over her arm.Wordlessly,she gave it to me.
"Is it finished?"I asked.
She shook her head."No.It is ready,"she replied.I handed her the money and took the blanket.
"It is beautiful,so skillfully woven(編織),"I said to my mother."But what did she mean when she said it was not finished?How can it be ready if it is not finished?"
"I will tell you later,"my mother said,"but first I will take you to the Navajo village."
We went down to the village.A group of young men were making sand pictures.We walked through the whole village,watching the different things the people were doing.
It was not until that evening that my mother finally explained the Navajo woman's words.
"Did you notice anything about the things the people were making?"my mother asked.
"What should I have noticed?"I looked at her and asked.
"Each thing the Navajo make has one small part that is not complete.The designs in their sand pictures are often not perfectly done,for example---the line of a circle may not quite close.If you look carefully at your blanket,you will probably find a stitch(一針)missing."
I took the blanket off,but it looked as perfect as any design could be.Then suddenly,I noticed that sure enough a stitch was missing!
"But why do the Navajo intentionally leave some tiny part unfinished?"I asked.
"They believe that when anything is completed or finished,it means the end has come--it will not be perfect until then.Then too,with a circle,they believe that they must leave a pathway for the bad spirits to run away and the good spirits to come in.So,often,they do not make the line close."
28.The blanket the author receivedB.
A.was poorly woven.B.made her think a lot.
C.cost her a lot of money.D.was finished,but not ready.
29.Why was the author shown around the village?C
A.To buy more things made by the Navajo.
B.To make friends with some of the Navajo.
C.To have a deeper understanding of the Navajo.
D.To look for the woman who sold her the blanket.
30.Which of the following may the Navajo believe?B
A.A stitch in time is very important.
B.Life only becomes perfect when you die.
C.He who makes no mistake is a perfect man.
D.You must always try to make your life complete.
31.What's the main idea of the text?C
A.The Navajo are good at making things.
B.The Navajo are brave and hard-working.
C.A blanket tells a lot about the Navajo culture.
D.Skills are needed to do business with the Navajo.

18.There was a man playing the piano in a bar.He was a good piano player and always performed in this bar.People came in just to hear him play.But one night,a customer told him that he didn't want to hear him just play the piano any more.He wanted him to sing a song.
The man said,"I don't sing."
But the customer was persistent (固執(zhí)的).He told the bar manager,"I'm tired of listening to the piano.I want that man to sing!"
The manager shouted across the room,"If you want to get paid,sing a song.Our customers are asking you to sing!"
So he did.He sang a song.A piano player who had never sung in public did so for the first time.And everyone was surprised by his song-"Mona,Mona Lisa".He got lots of applause (掌聲) that night.
He had such a talent for singing,but he just had been sitting on his talent for the past years!If without such a chance,he may have lived the rest of his life as a no-name piano player in a no-name bar.However,now he had become one of the best-known singers in America.
You,too,have skills and abilities.Maybe your"talent"is not as great as the singer above,but it may be better than you think!And with effort,most skills can be improved.So,in your life,you should be brave enough to try doing different things and find out what talents you really have!

29.Why did the man start to sing?C
A.Because he wanted to make more money.
B.Because the bar manager said he liked his song.
C.Because the manager asked him to sing at the request of a customer.
D.Because he wanted to show everyone that he had a talent for singing.
30.What do you think of the bar manager?B

15.Two graduates from Cambridge University in the United Kingdom found themselves about to graduate,yet with loans (貸款) to pay off.The pair decided to begin a strange,year-long project to battle their debt.
The men,Ross Harper and Ed Moyse,set up the site BuyMyFace.co.uk.last October as a way to get rid of the 80,000they shared as student loans.The idea behind the project was to earn money by selling their faces as advertising space every day for a year.Each day,they advertise a different business on their site by painting the brand's logo (商標) or name on their faces and including a link to the company's site.After they paint their faces and publish them on the site,Harper and Moyse go out to highly populated areas such as music festivals and theme parks to maximize their faces'exposure.At this time,Harper and Moyse have advertised their faces for over four months without skipping a day and they're more than halfway to their goal.Though they first started charging a minimum of about USD   1.60 per company,the prices have risen as their popularity increased.For advertising space during the remainder of April,they range between USD   250 and   750.
Terri L.Rittenburg,associate professor of marketing at the University of Wyoming,said she had heard of people tattooing (紋身) logos on themselves before,but this idea is much better.According to her,at first the idea would be new and novel and attract attention,but she is unsure how long it would last.
At least for now,companies that have bought Harper and Moyse's faces have written positive comments on the pair's website."We had a three percent increase in website traffic (流量) on the very day and for two days more afterwards,"said an alcoholic beverage company.
71.Which of the following was most possibly taken from the website BuyMyFace.co.uk.?D

72.At BuyMyFace.co.uk,you canAof the company being advertised for.
A.click to enter the website               B.download product pictures
C.get in touch with the staff              D.read a brief introduction
73.Harper and Moyse go to highly populated areas toC.
A.have fun       B.make friends       C.show their faces  D.find new customers

B.a(chǎn)ren't getting on well with their project
C.may close their site next month

16.It is easy to find your way about in New York.It is laid out so regularly.Instead of streets winding and twisting (迂回) as they do in London,they are all regular and well planned.The streets running north and south are called"avenues"and are numbered,e.g.1st Avenue,2nd Avenue,etc.The streets going east and west are called"streets"and are also numbered,e.g.51st Street,63rd Street.It is all much more logical (合理的) than London's street names.But I couldn't help thinking how much more interesting than these dull cold numbers are London's illogical but colorful names of streets,e.g."Bishopgate"(which is not a gate and hasn't a Bishop in it);"Haymarket"or"Corn market"(where you won't see any hey or corn) or"Poultry"(without a living chicken anywhere in sight) or"Thread needle Street"(where you won't find little girls learning to sew).
