1 . One of the curious things about social networks is the way that some messages, pictures, or ideas can spread like wildfire while others that seem just as catchy or interesting barely register at all.
Before you go deep into the puzzle, consider this: If you measure the height of your male friends, for example, the average is about 170 centimeters. You are 172 and your friends are all about the same height as you are. Indeed, the mathematical concept of “average” is a good way to capture the nature of this data set.
But imagine that one of your friends was much taller than you. This person would dramatically skew the average, which would make your friends taller than you, on average. In this case, the “average” is a poor way to capture this data set.
Exactly this situation occurs on social networks. On average, your coauthors will be cited more often than you, and the people you follow will post more frequently than you, and so on.
Now Lerman from University of Southern California has discovered a related paradox, which they call the majority illusion. They illustrate this illusion with an example. They take 14 nodes linked up to form a small network. They then color three of these nodes and count how many of the remaining nodes link to them in a single step.
In one situation, the uncolored nodes see more than half of their neighbors as colored. This is the majority illusion — the local impression that a specific feature is common when the global truth is entirely different.
So how popular is it in the real world? It’s found out that the majority illusion occurs in almost all network scenarios. “The effect is largest in the political blogs network, where 60% of nodes will have majority active neighbours, even when only 20% of the nodes are truly active,” says Lerman.
It immediately explains many interesting phenomena. For a start, it shows how some content can spread globally while other similar content does not — the key is to start with a small number of well-connected early adopters fooling the rest of the network into thinking it is common. The affected nodes then find it natural to follow the trend. A real spread finally comes into being.
But it is not yet a marketer’s charter. For that, marketers must first identify the popular nodes that can create the majority illusion for the target audience. These influencers must then be persuaded to adopt the desired behavior or product, which is essential to the prospect of the marketing plan.

2 . Every decision we make is arrived at through hugely complex neurological processing. Although it feels as though you have a choice, the action that you ‘decide’ to take is entirely directed by automatic neural activity. Brain imaging studies show that a person’s action can be predicted by their brain activity up to 10 seconds before they themselves become aware they are going to act. Multiple neuroscientific studies show that even those important decisions that feel worked out are just as automatic as knee-jerk reactions (膝跳反应) (although more complex).
Decision-making starts with the amygdala: a set of two almond-shaped nuclei (杏仁状核) buried deep within the brain, which generate emotion. The amygdala registers the information streaming in through our senses and responds to it in less than a second, sending signals throughout the brain. These produce an urge to run, fight, freeze or grab, according to how the amygdala values various stimuli.
Before we act on the amygdala’s signals, however, the information is usually processed by other brain areas, including some that produce conscious thoughts and emotions. Areas concerned with recognition work out what’s going on, those concerned with memory compare it with previous experiences, and those concerned with reasoning, judging and planning get to work on constructing various action plans. The best plan—if we are lucky—is then selected and carried out. If any of this process goes wrong, we are likely to hesitate, or do something silly.
The various stages of decision-making are marked by different types of brain activity. Fast (gamma)waves, with frequencies of 25 to 100 Hz, produce a keen awareness of the multiple factors that need to be taken into account to arrive at a decision. If you are trying to choose a sandwich, for instance, gamma waves generated in various cells within the ‘taste’ area of the brain bring to mind and compare the taste of ham, hummus, wholemeal, sourdough, and so on. Although it may seem useful to be aware of the full range of choice, too much information makes decision-making more difficult, so irrelevant factors get dismissed quickly and unconsciously.
After this comparison stage, the brain switches to slow-wave activity (12 to 30 Hz). This extinguishes most of the gamma activity, leaving just a single ‘hotspot’ of gamma waves which marks the chosen option.
Although there is no ‘you’ outside your brain to direct what it’s doing, you can help it to make good decisions by placing yourself in a situation which is likely to make the process run more smoothly. Doing something that is physically or mentally stimulating before making a decision will help your brain produce the initial gamma waves that generate awareness of the competing options. Getting over-excited, on the other hand, will prevent the switch to the slow brainwaves, making it much harder to single out a choice.

| C．It dismisses factors that are irrelevant to the decision to be made. |
| D．It processes sensory information and generates emotional responses. |
| A．Slow-wave activity usually lasts longer than fast-wave activity. |
| B．The brain prioritizes information before settling on a final choice. |
| C．Decision-making is difficult when slow-wave activity occurs first. |
| D．The brain needs as much information as possible to make a decision. |
| A．By preparing the brain to single out the most reasonable choice. |
| B．By helping the brain switch to slow-wave activity more quickly. |
| C．By getting the brain to focus on those most relevant alternatives. |
| D．By making the brain more aware of the factors and choices involved. |
3 . Experienced⁃Based Education
Everyone is familiar with traditional education. You sit in a class and a teacher teaches. This is an important part of development. But at some point, every individual has to take charge of their own education. To do this, one must look at the root of learning.
Basically, unfamiliar experiences usually add more value than experiences that are familiar.
High school is a new experience. College is a new experience. However, at some point traditional education becomes repetitive. It is not that you won’t learn anything else, but that the environment is so familiar.
To solve this, an individual needs to introduce new experiences into their life. You may spend a summer in a different part of the country or learn a new language through trial and error. You can also go to a drive⁃in movie（or some other entertainment event that is new to you）.
These types of experiences often result in very little“book knowledge”. Instead, they will often provide you with a better understanding of yourself as you experience your reaction to different situations.
| A．Has education changed so much in the last decade? |
| B．They will also provide you with a better understanding of others. |
| C．Those new experiences may not lead to great personal development. |
| D．These are all things that can stretch and expand your experience in life. |
| E．This is because unfamiliar experiences require much more of our attention. |
| F．As a result, you can easily become less aware of your experience and not learn as much. |
| G．What makes some experiences add great value to our lives while other experiences do not? |

5 . A robot created by Washington State University (WSU) scientists could help elderly people with dementia (痴呆) and other limitations live independently in their own homes.
The Robot Activity Support System, or RAS, uses sensors installed in a WSU smart home to determine where its residents are, what they are doing and when they need assistance with daily activities. It navigates (定位) through rooms and around obstacles to find people on its own, provides video instructions on how to do simple tasks and can even lead its owner to objects like their medication or a snack in the kitchen.
“RAS combines the convenience of a mobile robot with the activity detection technology of a WSU smart home to provide assistance in the moment, as the need for help is detected,” said Bryan Minor, a postdoctoral researcher in the WSU School of Electrical Engineering and Computer Science.
Currently, an estimated 50 percent of adults over the age of 85 need assistance with every day activities such as preparing meals and taking medication and the annual cost for this assistance in the US is nearly $2 trillion. With the number of adults over 85 expected to triple by 2050, researchers hope that technologies like RAS and the WSU smart home will relieve some of the financial strain on the healthcare system by making it easier for older adults to live alone.
RAS is the first robot researchers have tried to incorporate into their smart home environment. They recently published a study in the journal Cognitive Systems Research that demonstrates how RAS could make life easier for older adults struggling to live independently.
“While we are still in an early stage of development, our initial results with RAS have been promising,” Minor said. “The next step in the research will be to test RAS’ performance with a group of older adults to get a better idea of what prompts, video reminders and other preferences they have regarding the robot.”
1. How does RAS serve elderly people?| A．Through sensors. | B．Through objects. |
| C．Through a mobile robot. | D．Through their daily activities. |
| A．It is the first robot used in daily life. | B．Its function remains to be tested. |
| C．It can locate people and do any task. | D．It can cook for owners on its own. |
| A．Doubtful. | B．Negative. |
| C．Optimistic. | D．Uncertain. |
| A．Elderly people leave the nursing home. |
| B．Smart Home Tests first elder-Care robot. |
| C．RAS, the first robot to make home smart. |
| D．Older adults have benefited from RAS. |
It’s the Saturday, 1:00 am, and Stormy, my dog, and I were going on a pre-dawn bird-watching adventure. The weatherman predicted fog, but as we hit the road, it’s clear. Along our journey, I stopped at a petrol station, ensuring Stormy was safely locked in the truck.
“Stormy, hang tight,” I whispered, stepping out into the night air.
Back on the highway, as we were near the marshlands, a heavy fog began to swallow everything. At a sharp bend, my truck hit soft ground, and I lost control. “Oh, no!” Panic set in as the vehicle slid off the road with a bang, falling down a steep bank and into the water.
In the strange silence that followed, I was floating inside the car, gently carried downstream by the canal. “Come on, door,” I said, switching uselessly at the handle. It won’t move; the electrical system had shorted out due to the water. “I’ve got a glass breaker,” I reminded myself, reaching for the tool in the center part.
With each failed attempt to break the window — the glass bouncing back at me — I felt a growing sense of urgency. Water moved over the floorboards, cooling my feet. “Stormy, stay calm,” I said, lying down to kick at the window with all my strength. But my efforts only met resistance.
As the water level rose threateningly close to the ceiling, fear clawed at my heart. In a last effort, I dived behind the seat for my toolbox. “Got to find something solid.” My hands brushed against the cold metal toolbox, then the fire extinguisher (灭火器). “This might work.”
“Here goes everything,” I thought, holding the extinguisher and hitting it against the window. The impact resounded through the car, but the glass holds firm. “Not yet,” I begged under my breath, as the extinguisher bounced harmlessly away.
The water kept rising, and so did my fear. A voice inside me screamed to give up, but another thought pierced through — Stormy. “For Stormy, I can’t quit.” Just then, I sensed a pause in the water’s rise.
An unspoken sound said, “You have more time. What will you do?”

As the international demand for narrative(叙事的) film/TV content continues to increase with popular streaming services like Netflix and others the two questions then come: will the coming generations receive most of their entertainment through visual means rather than through the written word and will such an increase of narrative film/ TV reduce the importance of reading?
Growing examples of this trend include the diminishment(减少) of fiction in the common core (核心的)curriculum, the ever－rising culture of computer games, the wave of streaming services of wide international reach, and movies filled with special effects made for children and teenagers. Nor must we ignore the economic dangers that lie ahead for the written word. The narrative film industry is a moneymaker that dwarfs(使相形见绌) the publishing industry.
The other underlying question, of course, is “does it really matter if the written word bows to the world of film/TV?” From my point of view, any diminishment of fiction delivered by words is a loss for mankind.
There is no greater human feature than the imagination. It lies at the very soul of the human species. It is the brain’s most powerful engine. It is the essential muscle of life and like all muscles it must be exercised and strengthened.
Writing and reading are the principal tools that inspire, create and empower our imagination. Anything that diminishes that power is the enemy of mankind.
It should be known that I am not opposed to new media and technological advances. Instead, I have always felt it necessary to adapt to advancing technology. In fact, a number of my novels are in various stages of development for film, TV, and live stage productions. My hope is that the written word will only stand to be complemented(补充)by its visual counterparts(对应物), not pushed to the edge of extinction.
Of course, there are those who will present arguments for the superiority of the moving image over the written word. Each has its place. My argument is for finding the right balance between it and the moving image.

As the school dress-up party was just around the corner, the school hall was full of children dressed in different shapes and colors. Some walked in as princes and princesses, some stepped in as superheroes and some made their dramatic entrance as astronauts and historical figures. But one little girl, whose name is Ellie, walked in, hiding her face and hoping nobody would take notice of her grey pants and white T-shirt.
Ellie wanted to dress up as a princess that year. Her dad had promised her a few months earlier that her costume would turn heads. But, her dad was so busy with all kinds of work that he forgot the small important things while dealing with the big important ones. When Ellie’s dad forgot to save up for her princess costume for the school dress-up party that year, she wasn’t mad at him. However, she couldn’t hold back her tears when the mean kids from her class started making fun of her. “What are you supposed to be dressed as? Ugly Ellie?” one of the boys laughed loudly. Ellie covered her ears and cried as she heard the kids crying out her latest name and laughing over and over again. Every face around her was unkind and indifferent to her sadness, making the poor girl feel more unconfident and alone.
“Follow me! Ellie!” an older voice whispered to her. It was Mr. Borges, her art teacher. He was trying to tell her something. The girl managed to escape the crowd of children and walk past them, closely following her teacher. “Wait here!” Mr. Borges told Ellie and walked away. A moment later, he returned and Ellie couldn’t help but wonder why Mr. Borges was holding a few rolls of toilet paper.

10 . If you’re reading this, it’s safe to assume you arrived by internet.
Maybe you caught the headline as it raced by on Twitter. Or you might be taking a break from watching a boring movie on Netflix.
It doesn’t matter. Because according to a new study, it all adds up to the same thing: one distraction（分心的事情）after another.
And the thing is, they’re welcome distractions. Because, as the research — published this week in the Journal of Personality and Social Psychology — notes, people will do just about anything to avoid being left to their own thoughts.
For their study, researchers designed a sample test for more than 2,557 participants in 11 countries. They divided their test subjects into two groups. In the first group, people were asked to spend 10 to 15 minutes “entertaining themselves with their thoughts as best they could.”
Just sit back and think about things. Sounds good, doesn’t it? Well, not really. The second group — the one where people were told to surf the Net, play a video game, or even read a book — reported having much more fun. They scored more highly on entertainment and lower on boredom. And the preference for distraction seemed to be a global phenomenon, which may come as a surprise to Italians who are famously brilliant at doing nothing.
“The preference for doing external（外部的）activities such as reading, watching TV, or surfing the internet rather than ‘just thinking’ appears to be strong throughout the world,” the researchers note in the study.
But there does seem to be an important thing that hasn’t been included in the study. Shouldn’t the quality of thoughts matter? If you’ve got something positive to think about — say, how you’re going to spend your vacation or the great screenplay you’ve already half-written in your head — why are you reading this?
On the other hand, if you are always bothered by negative thoughts — a sad or painful experience, perhaps — by all means, keep scrolling（翻网页）.
Unfortunately, we won’t be able to take up much of your time here; it’s a short study that gets to the point in a hurry. Don’t worry though. There’s a whole world of distractions out there. Say, have you seen that ship teetering at the brink of Niagara Falls? And how about those charming cows? Bet you didn’t know they could smell you from six miles away.
And that’s something to think about.
1. Why would the Italians be surprised at the phenomenon?| A．They prefer reading books to surfing the Net. |
| B．They’re convinced that thinking is significant. |
