You don't need to get in a time-traveling machine to see how technology will reshape our lives, such as the way we shop.Several new technologies that are to change your buying habits already exist.Let's see what's in store for your future shopping.
Try it on, virtually (虛擬的).Want to shop online for a new pair of eyeglasses? You don't need to guess which pair looks best on you. Go and see the eBay Fashion iPhone app to try a pair of eyewear you're checking out on a picture of your face.But what if you want to buy something bigger? Thanks to Microsoft Kinect's motion tracking camera, you can cover clothes on your screen body.You can even choose the background of your virtual fitting room to enrich your shopping experience.
Get a perfect, custom fit.Everyone's body is shaped differently.To get a perfect fit, you sometimes have to get your clothes changed.But by using 3D scanning technology, all the clothes you buy will fit your body perfectly.Some companies scan your body using High-tech to get the most accurate measurements, so they can make special clothes just for you.
High-tech shopping carts and checkout counters.High-tech shopping carts could, in time, be a common sight in malls and supermarkets.Microsoft Kinect-enabled carts are currently under test.The cart can follow you along the aisles (通道), controlled merely by your movement and your voice.In China, a supermarket chain introduced tablet-equipped carts that guide shoppers around the stores' aisles.
In the United States, several supermarkets use a device called Scan It that gives buyers the freedom to scan purchases on their own while they shop.While it's great not having to line up at a checkout counter, we wouldn't mind it if the store used Toshiba's new Object Recognition Scanner.The machine identifies a product as soon as it's placed in front of a camera just by its shape and color, even if it has no bar code.

Can people change their skin color without suffering like pop king Michael Jackson? Perhaps yes. Scientists have found the gene that determines skin color.
The gene comes in two versions, one of which is found in 99 percent of Europeans. The other is found in 93 to 100 percent of Africans, researchers at Pennsylvania State University report in the latest issue of Science.
Scientists have changed the color of a dark-striped zebra-fish(斑馬魚(yú)) to uniform gold by inserting a version of the pigment (色素) gene into a young fish. As with humans, zebra-fish skin color is determined by pigment cells, which contain melanin (黑色素). The number, size and darkness of melanin per pigment cell determine skin color.
It appears that, like the golden zebra-fish, light-skinned Europeans also have a mutation (變異) in the gene for melanin production. This results in less pigmented skin.
However, Keith Cheng, leader of the research team, points out that the mutation is different in human and zebra-fish genes.
Humans acquired dark skin in Africa about 1.5 million years ago to protect bodies from ultra-violet rays of the sun (太陽(yáng)光紫外線), which can cause skin cancer.
But when modern humans leave Africa to live in northern latitudes, they need more sunlight on their skin to produce vitamin D. So the related gene changes, according to Cheng.
Asians have the same version of the gene as Africans, so they probably acquired their light skin through the action of some other gene that affects skin color, said Cheng.
The new discovery could lead to medical treatments for skin cancer. It also could lead to research into ways to change skin color without damaging it like chemical treatment did on Michael Jackson.
【小題1】The passage mainly tells us that ________.
A.people can not change their skin color without any pain |
B.the new discovery could lead to research into ways to change skin color safely |
C.pop king Michael Jackson often changed his skin color as he liked |

A.nowadays people who want to change their skin color have to suffer a lot from the damage caused by the chemical treatment |
B.Europeans and Africans have the same gene |
C.the new discovery could help to find medical treatments for skin cancer |
D.there are two kinds of genes |
A.find the different genes of humans’ |
B.prove the humans’ skin color is determined by the pigment gene |
C.find out the reason why the Africans’ skin color is dark |
D.find out the ways of changing people’s skin color |
A.they are born light-skinned people |
B.light-skinned Europeans have mutation in the gene for melanin production |
C.they have fewer activities outside |
D.they pay much attention to protecting their skin |
A.neutral | B.negative | C.positive | D.unconcerned |

Hu Li's heart sank due to the color of the air.Driving 140 kilometers from Tianjin City to Beijing last week,she held her breath as the air became a charcoal grey haze(炭灰色的陰霾).The 39yearold businesswoman has lived in Beijing for a decade,and this past month,she said,brought the worst air pollution she has ever seen.It gave her husband a cough and left her sevenyearold daughter housebound(足不出戶(hù)).“My husband as well as I is working here,so we have no choice,” she said.“But if we had a choice,we'd like to escape from Beijing.”
The extended heavy pollution over the last month,which caused punishment in return for a day last week-called the “airpocalypse” by internet users- has largely changed the way that Chinese think about the country's air.On one day,pollution levels were 30 times higher than levels considered safe by the World Health Organization (WHO).Flights were cancelled.Roads were closed.One hospital in east Beijing reported they had treated more than 900 children for breathing issues.Bloomberg found that for most of January,Beijing's air was worse than that of an airport smoking area.
The smog's(煙霧) most threatening aspect is its high concentration(濃度) of PM 2.5 - particulate matter that is small enough to breathe deep into the lungs and enter the bloodstream,causing breathing infections,lung cancer and possibly damaging children's development.The WHO has estimated that outdoor air pollution accounts for two million deaths per year,65% of them in Asia.
【小題1】Which conclusion can we draw from the first paragraph?
A.Hu Li is living in Beijing. |
B.Hu Li traveled to Tianjin for business. |
C.The haze is harmful to people. |
D.The pollution is the worst in Beijing's history. |
A.the way they traveled |

The first flights of the new airlines that will take tourists into space are ready to take off in 2012, and getting a seat on one is not all that different from booking a trip someplace on Earth. You can sign up on the website of, say, Virgin Galactic,the most wellknown of the new space tourism companies, or go to an approved travel agency and put down a large deposit. Soon you will be able to buy travel insurance,just as you can for any other vacation.
Until now,space tourism has been limited to the ultrawealthy. Just seven people have paid tens of millions of dollars each for a trip to the International Space Station aboard a Russian rocket.
But that could change this year, when Virgin Galactic intends to start offering flights just beyond the space barrier on a rocket ship it has built, featuring five minutes of weightlessness during a twoandahalfhour tour. At $ 200,000 a seat, this will open the final frontier to far more people.
At least two other specialty airlines have jumped in as well, taking reservations and deposits for future space flights.Allianz, the big insurer, will introduce an insurance product in 2012, lending space tourism the trappings of the regular travel industry.
“Just to be able to sell space travel as a regular part of your business, really, just how cool is that?” said Lynda Turley Garrett, president of Alpine Travel of Saratoga, Calif.,who is one of 58 accredited space agents for Virgin Galactic in the United States.
In five years,Ms.Garrett has sold three seats. But she expects that to change once passengers start going up and coming down to tell their friends. “By 2017,it'll be just like scheduling a flight to L.A.,” Ms.Garrett predicted.
【小題1】If you want to book a flight to space in 2012, you can________.
A.go to any travel agency |
B.telephone Virgin Galactic |
C.pay a visit to Allianz |
D.sign up on the website of Virgin Galactic |
A.only the extremely rich people can afford the space trip |
B.seven people have paid tens of millions of dollars for a space trip |
C.Russia is the first country to build the space station |
D.ordinary people are not allowed to take space tour |
A.It is one of the approved space agencies. |
B.It is a famous space tourism company. |
C.It sells insurance products to space tourists. |
D.Its rocket has carried space passengers successfully. |

A black hole is a place in space where gravity pulls so much that even light cannot get out. The gravity is so strong because matter has been squeezed into a tiny space. This can happen when a star is dying.
Because no light can get out, people can’t see black holes. Space telescopes with special tools can help find black holes. The special tools can see how stars that are very close to black holes act differently from other ones.
Black holes can be big or small. Scientists think the smallest black holes are as small as just one atom. These black holes are very tiny but have the mass of a large mountain. Mass is the amount of matter, or “staff”, in an object.
Another kind of black hole is called “stellar”(星球黑洞). Its mass can be up to 20 times more than the mass of the sun. There may be many stellar mass black holes in Earth’s galaxy. Earth’s galaxy is called the Milky Way.
The largest black holes are called “supermassive”(超大質(zhì)量黑洞). These black holes have masses that are more than one million suns together. Scientists have found proof that every large galaxy contains a supermassive black hole at its center. The supermassive black hole at the center of the Milky Way galaxy has a mass equal to about four million suns and would fit inside a very large ball that could hold a few million Earths.
Scientists think the smallest black holes formed when the universe began. Stellar black holes are made when the center of a very big star falls in upon itself, or falls apart. When this happens, it exploded part of the star into space. Scientists think supermassive black holes were made at the same time as the galaxy they are in.
A black hole can not be seen because strong gravity pulls all of the light into the middle of the black hole. But scientists can see how the strong gravity affects the stars and gas around the black hole. Scientists can study stars to find out if they are flying around, or orbiting a black hole.
When a black hole and a star are close together, high-energy light is made. This kind of light cannot be seen with human eyes. Scientists use satellites and telescopes in space to see the high-energy light.
【小題1】The gravity of a black hole may become so strong that light cannot get out when ____________.
A.the star is going to die |
B.special tools are used on it |
C.other stars come close to it |
D.it is seen from the space telescopes |
A.A black hole can be very tiny but extremely heavy. |
B.The gravity of a black hole holds all light in its center. |
C.Scientists observe high-energy light through their own eyes. |
D.Some small black holes came into being as early as the universe. |
A.a(chǎn) black hole | B.the Milky Way |
C.a(chǎn) series of stars | D.a(chǎn) planet near the earth |
A.Neither the sun nor the earth is as heavy as a black hole. |
B.There is a supermassive black hole at the center of the Milky Way. |
C.The supermassive black hole had existed before the Milky Way was formed. |
D.There is a reason why the large black holes are called “supermassive”. |
A.what a black hole is |
B.how black holes form |
C.how big black holes are |
D.how scientists know about black holes |

Play allows children to use their creativity while developing their imagination and physical, cognitive (認(rèn)知的), and emotional strength. Play is important to healthy brain development. Play allows children to create and explore a world they can master, conquering their fears while practicing adult roles. Undirected play allows children to learn how to work in groups, to share, to negotiate, and to resolve conflicts.
Ideally, much of play involves adults, but when play is controlled by adults, children acquiesce (順從) to adult rules and concerns and lose some of the benefits play offers them, particularly in developing creativity, leadership, and group skills. In contrast to passive entertainment, play builds active, healthy bodies. In fact, it has been suggested that encouraging unstructured play may be an exceptional way to increase physical activity levels in children, which is one important strategy in the resolution of the obesity problem.
Children’s development is critically influenced by appropriate, affective relationships with loving and consistent caregivers as they relate to children through play. When parents observe their children in play or join with them in child-driven play, they are given a unique opportunity to see the world from their children’s vantage point as the child navigates a world perfectly created just to fit his or her needs. The interactions that occur through play tell children that parents are fully paying attention to them and help to build enduring relationships. Parents who have the opportunity to look at their children’s world learn to communicate more effectively with their children and are given another setting to offer guidance. Less verbal children may be able to express their views, giving their parents an opportunity to gain a fuller understanding of their perspective. Quite simply, play offers parents a wonderful opportunity to engage fully with their children.
Play is essential to the academic environment. It ensures that the school setting attends to the social and emotional development of children as well as their cognitive development. It has been shown to help children adjust to the school setting and even to strengthen children’s learning willingness. Social-emotional learning is best integrated (融合) with academic learning; it is concerning if some of the forces that enhance children’s ability to learn are improved at the expense of others. Play and unscheduled time that allow for peer interactions are important components of social-emotional learning.
【小題1】Compared with undirected play, play which is controlled by adults ________.
A.doesn’t benefit the children at all |
B.doesn’t help develop leadership and group skills |
C.makes children become more active |
D.helps increase physical activity levels |
A.play offers parents a good chance to establish good relationships with children |
B.children’s development is greatly influenced by relationships with parents |
C.play helps children better express their views |
D.play offers parents a unique opportunity to see the world from a different perspective |
A.play can’t help children become adapted to the school setting |
B.play makes social-emotional learning and academic learning separated |
C.play is beneficial to social-emotional learning as well as academic learning |
D.it is necessary to strengthen children’s academic development at the expense of others |
A.Undirected play can help children develop team spirit. |
B.Play can improve children’s willingness to learn. |
C.Play helps adults gain a better understanding of the children’s thoughts. |
D.Adults shouldn’t be involved in children’s play. |

At the moment, there are two reliable ways to make electricity from sunlight. You can use a panel of solar cells to create the current directly, by liberating electrons from a semiconducting material such as silicon. Or you can concentrate the sun’s rays using mirrors, boil water with them, and employ the steam to drive a generator.
Both work. But both are expensive. Gang Chen of the Massachusetts Institute of Technology and Zhifeng Ren of Boston College therefore propose an alternative. They suggest that a phenomenon called the thermoelectric(熱電)effect might be used instead—and they have built a prototype(原型)to show that the idea is practical.
Thermoelectric devices are not new. They are used, for example, to capture waste heat from car engines. They work because certain materials generate an electrical potential difference within themselves if one part is hotter than another. That can be used to drive a current through an external circuit.
The reason thermoelectric materials have not, in the past, been applied successfully to the question of solar power is that to get a worthwhile current you have to have a significant temperature difference. (200℃ is considered a good starting point.) In a car engine, that is easy. For sunlight, however, it means concentrating the heat in some way. And if you are going to the trouble of building mirrors to do that, you might as well go down the steam-generation route, which is a much more efficient way of producing electricity. If the heat concentration could be done without all the equipment of mirrors, though, thermoelectricity’s inefficiency would be balanced by the cheapness of the equipment.
In their view, three things are needed to create a workable solar-thermoelectric device. The first is to make sure that most of the sunlight which falls on it is absorbed, rather than being reflected. The second is to choose a thermoelectric material which conducts heat badly but electricity well. The third is to be certain that the temperature gradient(梯度)which that badly conducting material creates is not wasted by poor design.
【小題1】The following methods can be adopted to make electricity from sunlight EXCEPT .
A.putting a panel of solar cells into use |
B.concentrating sun’s rays with mirrors |
C.creating a solar-thermoelectric device |
D.building a practical solar prototype |
A.Because it’s hard for them to build enough mirrors to make it work. |
B.Because 200℃ was hard to reach at that time even in a car engine. |
C.Because of the failure of having a significant temperature difference. |
D.Because it was hard to focus the sun’s rays with equipment of mirrors. |
A.Thermoelectric Device --- the Best Method of All |
B.A New Method of Making Electricity from Sunlight |
C.How to Create a Workable Thermoelectric Device |
D.Solar Power --- a New Energy Trend in the Future |

Your brain isn’t a muscle, but you can treat it like one
Many people focus on physical fitness, but few know that brain fitness is also something you can work on. In fact, you can exercise your brain as often as you do to your arms or legs —and the results can be positive and empowering.
To improve your brain, you can’t simply repeat the same exercises over and over. Just as lifting a two—pound weight will stop challenging you, so will repetitive exercises such as crosswords or Sudoku. Once you master easy exercises, you must move on to harder ones in order to push your brain —like your muscles —to a new level.
The science behind brain training
Scientists once believed that your mental abilities were fixed in adulthood. Since studies have shown just the opposite, millions of people around the world have adopted the new practice of brain training. The most popular of these brain training products is made by the San Francisco—based Lumosity. Lumosity's scientists with an experienced team of game designers have developed a fun,effective online brain training program that measures,tracks,and adapts to your progress,so you'll always be challenged.
Promising studies on the effects of brain training
In a 2013 Stanford study,a treatment group of 21 breast cancer survivors used 12 weeks of Lumosity training to work on processing speed,mental flexibility,and working memory tasks. On average,those who trained improved on tests of these abilities,compared to a group that did not train with Lumosity.
There is even some evidence suggesting that Lumosity may be beneficial to normal,healthy adults. In a 2011 study by Lumosity and San Francisco State University researchers. 13 people who trained over 5 weeks improved working memory scores by 10%and attention scores by 20%.
Brain training is designed to meet real-life needs
The design of brain training is targeted at real-life benefits instead of improving game scores. Better attention,for example,can mean greater focus in the classroom or at an important business meeting. With improved processing speed,you might react and adapt faster to the demands of a busy life. And a better memory could mean stronger,longer relationships with the people closest to you.
【小題1】We can learn from the passage that _________.
A.brain training speeds up the recovery of breast cancer |
B.your brain is like a muscle because it gives you power |
C.people's mental abilities can't develop after they grow up |
D.Lumosity can measure,track and suit your level as you improve |
A.Better attention. | B.A better memory. |
C.Better writing skills. | D.Higher processing speed. |
A.People should care more about physical health instead of mental health. |
B.Brain training has been proved effective through scientific researches. |
C.A bad memory is the only reason for weak relationships with people. |
D.Playing online games is the best way of brain training. |
A.Brain Training Makes a Difference | B.Train Your Brain like a Muscle |

“Choo, Choo!” Here comes the Chunnel train. Get aboard if you want to learn more about this underground transportation system. This is an unusual form of transportation, because it is a tunnel that trains travel through and not an actual form of transportation.
The Chunnel is actually the English nickname for the Channel Tunnel. In French, it is called le tunnel sous la Manche. It is a rail tunnel beneath the English Channel at the Straits of Dover. It connects Cheriton in Kent, England with Sangatte in northern France. It is the second longest rail tunnel in the world.
Did you know that the British and the French had a race whi1e they were building the Chunnel? The race was to see who could get to the middle of the tunnel first. The British won by a little bit. It took 15,000 workers over seven years to dig the tunnel. The tunnel was finished in 1994.
The completed Chunnel cost about $ 21 billion. But it all paid off, because it became very popular, very quick. Millions of people use it. Now it is getting even more popular.
There are three complete tunnels in the Chunnel. The two outside ones are the passenger trains. The small inner one is a guidance train. The guidance train is not used for transportation. Each track is exactly parallel to each other.
There are four different train systems in the Chunnel. The Eurostar is a high speed passenger service that connects London, Paris, Brussels, and Lille. The Eurotunnel shuttle is a rail ferry service. These shuttles carry cars. These are railcars that allow drivers to drive their vehicles on and off. There are also two Eurotunnel goods service trains.
Now you know more about the Chunnel. Everybody off, this is the last stop.
【小題1】The Channel Tunnel links ______ with _______.
A.Dover; Kent | B.London; Paris | C.Lille; Brussels | D.Cheriton; Sangatte |
A.passengers | B.drivers and their vehicles |
C.goods | D.staff members of the Chunnel |
A.found in a textbook | B.read in a magazine |
C.broadcast on a train | D.heard in a railway station |
