Imagine you’re at a party full of strangers. You’re nervous. Who are these people? How do you start a conversation? Fortunately, you’ve got a thing that sends out energy at tiny chips in everyone’s name tag (标签). The chips send back name, job, hobbies, and the time available for meeting-whatever. Making new friends becomes simple
This hasn’t quite happened in real life. But the world is already experiencing a revolution using RFID technology.
An RFID tag with a tiny chip can be fixed in a product, under your pet’s skin, even under your own skin. Passive RFID tags have no energy source-batteries because they do not need it. The energy comes from the reader, a scanning device, that sends out energy (for example, radio waves) that starts up the tag immediately.
Such a tag carries information specific to that object, and the data can be updated. Already, RFID technology is used for recognizing each car or truck on the road and it might appear in your passport. Doctors can put a tiny chip under the skin that will help locate and obtain a patient’s medical records. At a nightclub in Paris or in New York the same chip gets you into the VIP (very important person) section and pays for the bill with the wave of an arm.
Take a step back:10 or 12 years ago,you would have heard about the coming age of computing. One example always seemed to surface: Your refrigerator would know when you needed to buy more milk. The concept was that computer chips could be put everywhere and send information in a smart network that would make ordinary life simpler
RFID tags are a small part of this phenomenon. “The world is going to be a loosely coupled set of individual small devices, connected wirelessly,” predicts Dr.J.Reich. Human right supporters are nervous about the possibilities of such technology. It goes too far tracking school kids through RFID tags, they say. We imagine a world in which a beer company could find out not only when you bought a beer but also when you drank it. And how many beers. Accompanied by how many biscuits. w*w*When Marconi invented radio, he thought it would be used for ship-to-shore communication. Not for pop music.

If your dog looks pleased to see you – it is probably because it loves the particular way you smell.
The odour of a familiar human apparently lingers like perfume in the animal’s brain – where it triggers an instinctive emotional response, research published yesterday reveals.
Our scent acts on a part of the canine brain associated with reward and the strongest reactions are produced by humans that pets know best, say scientists in America.
Gregory Berns, of Emory University in Atlanta, said: ‘While we might expect that dogs should be highly tuned to the smell of other dogs, it seems that the “reward response” is reserved for their humans.
'When humans smell the perfume or cologne of someone they love, they may have an immediate, emotional reaction that's not necessarily cognitive.
'Our experiment may be showing the same process in dogs. But since dogs are so much more olfactory(嗅觉的) than humans, their responses would likely be even more powerful than the ones we might have.
'It's one thing when you come home and your dog sees you and jumps on you and licks you and knows that good things are about to happen.
'In our experiment, however, the scent donors were not physically present.
Why do animals avoid pylons? Because they emit terrifying flashes of light that are INVISIBLE to humans.
Dolphins use sponges to protect their sensitive noses while foraging for food on the sea floor
'That means the canine brain responses were being triggered by something distant in space and time. It shows that dogs' brains have these mental representations of us that persist when we're not there.'
The university’s experiment - the first of its type - involved 12 dogs of various breeds who underwent brain scans while five different scents were placed in front of them.
The scent samples came from the subject itself, a dog the subject had never met, a dog that lived in the subject's household, a human the dog had never met, and a human that lived in the subject's household.
The familiar human scent samples were taken from someone else from the house other than the handlers during the experiment, so that none of the scent donors were physically present.
The results showed that all five scents elicited a similar response in parts of the dogs' brains involved in detecting smells. Responses were significantly stronger for the scents of familiar humans, followed by that of familiar dogs.
The findings, which were published in the journal Behavioural Processes, showed that dogs reacted strongest to the scent of a familiar human even when they were not there.
Pets trained as help or therapy dogs showed greater brain activity than the other dogs in the test.
Researchers say the findings could improve the way animals who assist wounded veterans or disabled people are selected.Why does your dog look pleased to see you ?
| A．because your dog wants to play with you |

Three-point-four billion riders on New York City subways and buses a year. This amazing number equals one-third of all mass transit trips in the United States. Ridership is at its highest in almost 60 years in almost every American city.
A commuter advocacy group, “Straphangers Campaign,” attributes it to younger Americans, said Gene Russianoff.
“Millenials（千禧一代）, those people born around the turn of the past century are much less car-oriented," he said. "They are urban. They like not owning cars, they like less responsibility and there are a lot of them."
In addition to millenials, many people believe public transit is economical and eco-friendly. In 2012 across America, people took 10.7 billion trips.
“When we talk about insurance rates going up, price of automobiles going up, then people are waking up and realizing: wait, here’s this huge asset(优点)that has been underutilized," said Richard Rudolph, chairman of the Rail Users Network. "Why not take advantage of this particular opportunity. It certainly makes more sense to get people out of automobiles into subways and into commuter and passenger railroads.”
New York is not standing still -- as passenger demand requires several major expansion projects. A new $4.5 billion subway line on New York’s Second Avenue -- which was recently excavated underneath businesses and apartment houses -- will take an overload of passengers off of other subway lines. Its first phase completion is scheduled in 2016.
People who work in New York’s financial district will soon be using a new transit subway transfer center. Almost all lines converge in lower Manhattan and the new center will give riders an easier way to get around the city and into New Jersey.
And, probably the most controversial and costly project is a $7 billion tunnel connection from Long Island into Manhattan’s Grand Central Terminal. Trains from there will have access to New York’s midtown business district.
Andrew Albert, a board member of the Metropolitan Transit Authority, said there were many other reasons the public was riding in increasing numbers.
“The system has gotten a lot more dependable. We have new cars. We have countdown clocks to tell you when the next train is coming. We have expanded facilities in places," he said.
New York’s 24-hour, 7-day-a-week, transit system costs a $1.5 billion a year to maintain. It is one of the world’s oldest, with its first subway line having opened in 1904. Who is more likely to use public transmit?
A.People living in suburb B.American young people
B.People living in the countryside D.American old people.What does the underlined word in the 5th paragragh “underutilized” mean?
| A．Not be put forward | B．not be noticed |
| C．not be made full use of | D．not be thought of |
What does the underlined sentence in the 6th paragragh “New York is not standing still” mean?
| A．New York is taking action to expand public transmit. |
| B．New York will encourage more people to use public transmit. |
| C．New York will make public transmit faster. |
| D．New York is waking up and realizing the importance of public transmit. |
Which is Not the reason why the public is riding subways and buses in increasing numbers.
| A．Public transport facilities are better than before. |
| B．Many people believe public transit is economical and eco-friendly. |
| C．The system has gotten a lot more dependable. |
| D．It is more convenient to ride city subways and buses. |
People say, you can not change the environment, but can change their own; you can not change the facts, but can change attitudes; you can not change the past, but can be changed now; you can not control other people, but can be masters of our own; you can not do everything well, but can be conscientious in everything; you can not about the weather, but you can change the mood; you can not choose looks, but it can show a smile.
Indeed, one key to the success lies in his (her) mind. The difference between successful people and the losers are: winners will be setbacks and difficulties due to personal ability, experience, imperfect, to emphasize the inherent, they are willing to continuously improve and develop the right direction; and the losers will blame on the opportunity, and the environment injustice, emphasizing external and uncontrollable factors that created the position of their life, they always complain, wait and give up!
In many cases, is a humble person who is looked down upon his own. Person's appearance, his family, and so a priori condition that can not be changed, but at least inner state, the spirit of the will is entirely their own control. Mentality, the final decision of life high. There is no absolute bad thing, only the mentality of the absolute poor people. If even the state of mind will not adjust, how they deal with things more complicated than the mentality of it!
No matter what the situation, a person's attitude is very important. Passion put to work, and numbness sluggish to work completely different. Emerson said: "A move toward their goals is always people who gave him the whole world to give way." On the contrary, failure is not because we do not have the strength, but because we are susceptible to all around us, used to go along with the lack of assertive, attitude unstable, easily frustrated reason.
As long as we believe that the strength of mind, change their attitude and courage to face a number of disappointments in life, do not despair, brave go on. I believe the power of mind, mind you're in the height of the final decision.The underlined word “humble” in Paragraph 3 probably means _____.
| A．ignoble | B．optimistic |
| C．lucky | D．stubborn |
Where can you probably find the text?
| A．In a popular magazine | B．In a tourist guidebook |
| C．In a physics textbook | D．In an official report |
Which of the following can be the best title for the passage?
| A．You can change nothing. |
| B．The Power of Mind. |
| C．The secret of success. |
| D．The difference between successful people and the losers |
Which best describes the writer’s tone in the passage?
| A．Approving. | B．Concerned. | C．Enthusiastic. | D．Encouraged |
Eight in 10 Americans eat fast food at least once a month and half eat it every week according, to a Gallup Poll. Yet most people who eat fast food know it’s bad for them. So why do they keep eating it?
The answer is simple: the benefits of eating fast food outweigh the long-term implications for most people. However, once you read these reasons why all those trips to the drive through may be slowly killing you, you may just want to stop eating fast food after all.
1. Fast food makes you fat.
A 15-year study of over 3,000 people found that eating fast food is linked to weight gain and insulin resistance. In others words, fast food makes you fat and increases your risk of type 2 diabetes. You probably know this already. But here’s something you may not know.
2. Fast food is addictive.
The more you eat fast food, the more you crave it. One study found that fast food is “a potentially addictive substance that is most likely to create dependence in vulnerable populations.” If you eat fast food once a week or more, you may be addicted to it.
3. Fast food is affecting your kids.
According to the CDC, childhood obesity has more than doubled in children and tripled in adolescents in the past 30 years. Kids have an amazing ability to recall ads they’ve seen. Fast food marketers know this, and design ads accordingly. Research shows strong associations between increases in advertising for non-nutritious foods and rates of childhood obesity.
4. Fast food “burgers” don’t have much burger in them.
One study found that most fast food burgers are composed of about 50 percent water and the actual meat content is only 2.1 to 14.8 percent. So what makes up the rest of it, you ask? Chemical fillers and preservatives, mostly. That’s why we see read horror stories about burgers that don’t go bad.
5. Even “healthy” fast food isn’t that healthy.
Fast food restaurants are catering to consumer demands to produce healthier options. The problem is, their definition of “healthy” is quite lax. One of the healthiest dishes at Burger King, the Garden Fresh Salad Chicken Caesar with TENDERGRILL Chicken and dressing, still has almost 500 calories and 28 grams of fat, and nearly a day’s worth of sodium.
6. Fast food is inhumane to animals.
Okay, this one may not be a reason why fast is killing you, but it’s still a compelling reason to stop eating fast food. 9 billion animals were slaughtered in the US alone in 2012 and much of that meat is for your fast food burgers and chicken sandwiches. Large factory farms resemble more of a “business” than a “farm.” Animals suffer in crowded spaces where they rarely have access to the outdoors or sunlight. They are pumped full of antibiotics to combat disease, which runs rampant in these conditions. Livestock is one of the biggest sources of pollution and environmental negligence, according to the UN.
7. Fast food sodas are loaded with sugar.
High fructose corn syrup (HFCS) is the cheap sweetener most fast food restaurants use in their sodas, desserts, and many other products. Princeton University researchers linked HFCS consumption to obesity in an animal study. Rats given HFCS gained more weight and body fat than those given table sugar.How many factors are mentioned which can account for the reason why fast food is slowly killing you?
| A．Seven. | B．Three. | C．Four. | D．Five. |
According to the text, we know that_____.
| A．many people keep eating fast food because they know nothing about the harm which fast food will bring them |
| B．fast food plays a key role in children’s growth |
| C．eating fast food is connected to weight gain and insulin resistance. |
| D．many fast food restaurants are can offer a good and healthy meal to consumer |
What is the purpose of the passage?
| A．To help us make right decisions | B．To advise us to stop eating fast food |
| C．To tell us how to keep fit | D．To encourage us to be humane to animals |
Human remains of ancient settlements will be reburied and lost to science under a law that threatens research into the history of humans in Britain, a group of leading archaeologists(考古学家) says. In a letter addressed to the justice secretary, Ken Clarke, 40 archaeologists write of their “deep and widespread concern” about the issue. It centers on the law introduced by the Ministry of Justice in 2008 which requires all human remains unearthed in England and Wales to be reburied within two years, regardless of their age. The decision means scientists have too little time to study bones and other human remains of national and cultural significance.
“Your current requirement that all archaeologically unearthed human remains should be reburied, whether after a standard period of two years or further special extension, is contrary to basic principles of archaeological and scientific research and of museum practice,” they write.
The law applies to any pieces of bone uncovered at around 400 dig sites, including the remains of 60 or so bodies found at Stonehenge in 2008 that date back to 3,000 BC. Archaeologists have been granted a temporary extension to give them more time, but eventually the bones will have to be returned to the ground.
The arrangements may result in the waste of future discoveries at sites such as Happisburgh in Norfolk, where digging is continuing after the discovery of stone tools made by early humans 950,000 years ago. If human remains were found at Happisburgh, they would be the oldest in northern Europe and the first indication of what this species was. Under the current practice of the law those remains would have to be reburied and effectively destroyed.
Before 2008, guidelines allowed for the proper preservation and study of bones of sufficient age and historical interest, while the Burial Act 1857 applied to more recent remains. The Ministry of Justice assured archaeologists two years ago that the law was temporary, but has so far failed to revise it.
Mike Parker Pearson, an archaeologist at Sheffield University, said: “Archaeologists have been extremely patient because we were led to believe the ministry was sorting out this problem, but we feel that we cannot wait any longer.”
The ministry has no guidelines on where or how remains should be reburied, or on what records should be kept.According to the passage, scientists are unhappy with the law mainly because _______.
| A．it is only a temporary measure on the human remains |
| B．it is unreasonable and thus destructive to scientific research |
| C．it was introduced by the government without their knowledge |
| D．it is vague about where and how to rebury human remains |
Which of the following statements is true according to the passage?
| A．Temporary extension of two years will guarantee scientists enough time. |
| B．Human remains of the oldest species were dug out at Happisburgh. |
| C．Human remains will have to be reburied despite the extension of time. |
| D．Scientists have been warned that the law can hardly be changed. |
What can be inferred about the British law governing human remains?
| A．The Ministry of Justice did not intend it to protect human remains. |
| B．The Burial Act 1857 only applied to remains uncovered before 1857. |
| C．The law on human remains hasn’t changed in recent decades. |
| D．The Ministry of Justice has not done enough about the law. |
Which of the following might be the best title of the passage?
| A．New discoveries should be reburied, the government demands. |
| B．Research time should be extended, scientists require. |
| C．Law on human remains needs thorough discussion, authorities say. |
| D．Law could bury ancient secrets for ever, archaeologists warn. |
