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. Who knows how RFID and related technologies will be used in the future. Here’s a wild guess: Not for buying milk.

Make the most of college
Dear Daughter,
As we drove off from Columbia, I wanted to write a letter to you to tell you all that is on my mind.
First, I want to tell you how proud we are. Getting into Columbia is a real testament（ 证明）of what a great well-rounded student you are. You should be as proud of yourself as we are.
Your college years will be the most important of your life. It is in college that you will discover what learning is about. This will be the period when you go from teacher-taught to master-inspired, after which you must become self-learner. So do take each subject seriously, and even if what you learn isn’t extremely impotant for your life, the learning skills you gain will be something you will cherish（怀念） forever.
Follow your passion in college. Take courses you think you will enjoy. Don’t be trapped by what others think or say, but make up your own mind.
Most importantly, make friends and be happy. College friends are often the best in life. Pick a few friends and become really close to them – pick the ones who are sincere and honest to you. Don’t worry about their hobbies, grades, looks or even personalities.
Start planning early – what would you like to do? Where would you like to live? What would you like to learn? I think your plan to study fashion is good, and you should decide where you want to be, and get onto the right courses.
Whether it is summer-planning, or coursework planning, or picking a major, or managing your time, you should take control of your life. I will always be there for you, but the time has come for you to be in the driver’s seat – this is your life, and you need to be in control. Being in control feels great. Try it, and you’ll love it!
College is the four years where you have:
lThe greatest amount of free time
lthe first chance to be independent
lthe most flexibility（灵活性）to change
lthe lowest risk for making mistakes
So please treasure your college years – make the best of your free time, become an independent thinker in control of your destiny（命运）, be bold（敢于冒险的） to experiment, learn and grow through your successes and challenges.
May your years at Columbia be the happiest of your life, and may you become just what you dream to be.

A gentle breeze blew through Jennifer’s hair. The golden red sun was setting. She was on the beach, looking up at the fiery (火红的) ball. She was amazed by its color, deep red in the middle, softly fading into yellow. She could hear nothing but the waves and the seagulls flying up above in the sky.
The atmosphere relaxed her. After all she had been through, this was what she needed. “It’s getting late,” she thought, “I must go home. My parents will be wondering where I am.”
She wondered how her parents would react when she got home after the three days she was missing. She kept on walking, directing herself where she spent every summer holiday. The road was deserted. She walked slowly and silently. Just in a few hundred meters she would have been safe in her house.
It was really getting dark now. The sun had set a few minutes before and it was getting cold too. She wished she had her favorite sweater on: it kept her really warm. She imagined having it with her. This thought disappeared when she finally saw her front door. It seemed different. Nobody had taken care of the outside garden for a few days. She was shocked: her father was usually so strict about keeping everything clean and tidy, but now... It all seemed deserted. She couldn’t understand what was going on.
She entered the house. First, she went into the kitchen where she saw a note written by her father. It said: “Dear Ellen, there is some coffee ready. I went looking.” Ellen was her mother but — where was she? On the right side of the hallway was her parents’ room. She went in. Then she saw her. Her mother, lying on the bed, was sleeping. Her face looked so tired, as if she hadn’t slept for days. She was really pale. Jennifer would have wanted to wake her up but she looked too tired. So Jennifer just fell asleep beside her. When Jennifer woke up, something was different... she wasn’t in her mother’s room and she wasn’t wearing the old clothes she ran away in. She was in her cozy bed in her pajamas (睡衣).
It felt so good being back home. Suddenly she heard a voice, “Are you feeling better now, dear? You know you got us very, very scared.”The writer describes the beautiful sunset to show Jennifer’s ______.
| A．love of the natural beauty |
| B．desire of getting back home |
| C．intention of becoming independent |
| D．depression of being alone |
What does the underlined phrase “This thought” most probably mean?
| A．The idea of going back home. |
| B．Her anxiety about her parents. |
| C．The feeling of being warm in her favorite sweater. |
| D．The feeling of getting back home safely. |
Her father didn’t take care of the garden because ______.
| A．he was busy looking for her |
| B．he had to look after his wife |
| C．he was not strict with his job |
| D．he no longer enjoyed working in the garden |
We might like to think we're not influenced by other people, but a new study into the group-buying mechanisms（机制） - like those used on coupon（优惠券） sites such as Groupon and LivingSocial - reveals that telling buyers who come later to the offer how many have already signed up increases the number of purchasers.
Researchers at the University of Toronto's Rotman School of Management wanted to understand why group buying sites that have entered the market recently have enjoyed greater success than those operating a decade ago, such as Mercata and MobShop.
Earlier attempts typically left potential buyers waiting for days before confirming whether or not they had got the offer they had signed up for.
“We think one of the reasons group-buying has been successful recently is because of the short time horizon,” says Rotman Professor Ming Hu, who co-wrote the study with Professor Mengze Shi and PhD student Jiahua Wu. “It allows for a herding effect.”
Another reason is the use of an information structure that discloses to later arrivals how many have already signed onto the deal.
Researchers looked at two ways of designing the purchasing mechanism for a group buy:a simultaneous mechanism, where no one knows how many buyers have come before them, and asequential（连续的） mechanism, where a second group of buyers has the advantage of knowing the size of the first group.
The researchers' analytical（分析的） model shows the most successful mechanism is the sequential one because it eliminates uncertainty for those coming later to the deal, and improves the confidence of those who sign on early, as they're able to track the numbers of those who come after them.
“That boosts confidence,” says Professor Hu, who teaches operations management. Deals for "luxury" services, versus everyday items, work better in a group buy scenario（方案） because they offer consumers a greater benefit.It can be learned from the text that ______.
| A．the short time horizon is the reason why group-buying has been successful. |
| B．a simultaneous mechanism is where a group of buyers has the advantage of knowing how many people have signed up. |
| C．a sequential mechanism allows a herding effect which boosts the confidence of the buyers. |
| D．researchers at the University of Toronto's Rotman School of Management carried out an experiment about why group buying sites entered the market successfully, such as Mercata and MobShop. |
The underlined word “eliminates” in paragraph 7 probably means“______”.
| A．to become or to make something greater in amount, number, value |
| B．to remove or get rid of something |
| C．to deliberately not include something in what you are doing or considering |
| D．to make something known to somebody |
What can be the best title for the passage?
| A．Secret for marketing success – boosting confidence. |
| B．Secret for group-buying mechanism—herding effect. |
| C．Comparison between a simultaneous mechanism and a sequential mechanism. |
| D．What others do influences our decisions. |
Mobile phones are an important business tool for farmers in rural areas. But they also put a valuable educational tool in their hands.
The University of Illinois in the United States has a project called SAWBO—Scientific Animations Without Borders. It produces educational videos that can be downloaded to cell phones. The goal is to help people in developing countries improve their lives.
One video shows farmers how to make a natural insecticide from neem seeds to prevent insect damage to crops. The process starts with sorting and drying the neem fruits. Then let the fruit dry in the sun for about three or four days, until they become brown. Using a mortar(碾槌) and stick, the fruits are slightly pounded to remove the shells from the fruits without breaking the seed inside.
The videos use computer animation(动画). Some of the animated characters are a little funny looking-like a farmer with a long nose. But the subjects are serious, including a health video on preventing cholera(霍乱). Team member Francisco Seufferheld says the information in the videos is meant to be quickly understood. He says, “The information is digested in such a way that in two minutes, we can transmit a complex idea.”
The researchers tested the seven-minute video on seven mobile phones. They wanted to see if people would share the video using Bluetooth wireless technology. With Bluetooth, files can be passed to a nearby phone even if neither phone is connected to the Internet. As a result, in one month, the video had spread to one hundred eighteen people in fifty different villages. “This is just incredible impact,” said Francisco Seufferheld.
The team has made a few videos so far. These are available in a total of eighty languages, dialects and accents. Professor Barry Pittendrigh says there are plans for more videos later this year. What is the text mainly about?
| A．A best-selling mobile phone |
| B．A valuable educational project for farmers |
| C．United States support for developing countries |
| D．A new type of scientist –farmer relationship |
The SAWBO program is introduced in order to ____.
| A．raise farmers’ standard of living |
| B．do some research on mobile phones |
| C．develop farmers’ practical skills |
| D．help farmers prevent insect damage to corps |
The biggest advantage of the program is that it______.
| A．includes health video on preventing cholera |
| B．can be passed to farmers using Bluetooth technology |
| C．can be used to sort and dry the neem fruits |
| D．is easy for farmers to understand |
Which of the following words can best take the place of the word “ pound” in the 3rd paragraph?
| A．moved | B．beat | C．picked | D．cut |
They may be small and not able to speak, but babies are proving their amazing cleverness. Scientists began finding infants’ skills are more than they are supposed to be.
_________
Speaking of music, babies can’t seem to resist it. Not only are their ears turned to the beats, babies can actually dance to the music.
To test babies’ dancing ability, the researchers played recordings of classical music, rhythmic beats and speech to infants, and recorded the results. They also invited professional dancers to analyze how well the babies matched their movements to the music. The babies moved their arms, hands, legs feet and heads in response to the music, much more than to the speech. The finding suggests this dancing ability is innate(与生俱来的) in humans, though the researchers aren’t sure why it becomes weaker later in their life.
Learning Quickly while Sleeping
Babies can learn even while asleep, according to a 2011 study. In experiments with 26 sleeping infants, each just 1 to 2 days old, scientists played a musical tone followed by a puff of air to their eyes 200 times over the course of a half-hour. 124 electrodes(电极) stuck on the head and face of each baby recorded brain activity during the experiments. The babies rapidly learned to foretell a puff of air upon hearing the tone, showing a four-time increase on average in the chances of tightening their eyelids in response to the sound by the end of the experiments.
As newborns spend most of their time asleep, this newfound ability might be crucial to rapidly adapting to the world around them and help to ensure their survival, researchers said.
Judging Characters Well
Judging another person helpful or harmful is crucial when choosing friends. And that ability starts early. Kiley Hamlin of Yale University showed both 6-and 10-month-olds a puppet(木偶) show, in which one character helped another climb a hill. In another scene a third character pushed the climber down. The little ones then got to choose which character they preferred. For both age groups, most babies chose the helper character. This character-judging ability could be baby’s first step in the formation of morals, Hamlin thought.Which of the following subtitles can fill in the underlined blank?
| A．Dancing to Music |
