I needed to do something in my community (社区) in order to complete the community service hours required to graduate from high school. Some of my friends had signed up to spend time at a soup kitchen, so I did, too. It seemed like a good thing to do.
I thought that we would just be passing out dinners to those in need, but I found out we would be doing everything from preparing to serving the dinner. We began preparing the food, from mixing salad dressing to separating frozen meat. Much still needed to be done before dinner was served, but already outside the building many homeless people were gathering. It wasn’t until a couple of hours later that we opened the doors and began serving dinner.
As the line of people came toward me, I got a little scared. I’d come face to face with the homeless: How should I act? How would they treat me? Would they hate me for having more than they did? While some of the people looked very friendly, some of them looked so dangerous. I didn’t have too much time to worry about it. I was assigned (分配) to serve the salad with the lady next to me. She smiled at me and said if I needed help, she’d be right there, which I found quite comforting.
I had never seen so many people wanting food. They were of all ages and nationalities. Most of them wore clothes that were torn and dirty. Some looked like they had tally given up on life, while others seemed to be making the best of the situation, smiling and joking. Some were better off than others, but they all needed a good meal and a warm place to eat. It saddened me to think of how many people there were who didn’t have a place to call home and the only food they got came from a soup kitchen.

2 . We may think we're a culture that gets rid of our worn technology at the first sight of something shiny and new, but a new study shows that we keep using our old devices(装置) well after they go out of style. That’s bad news for the environment — and our wallets — as these outdated devices consume much more energy than the newer ones that do the same things.
To figure out how much power these devices are using, Callie Babbitt and her colleagues at the Rochester Institute of Technology in New York tracked the environmental costs for each product throughout its life — from when its minerals are mined to when we stop using the device. This method provided a readout for how home energy use has evolved since the early 1990s. Devices were grouped by generation — Desktop computers, basic mobile phones, and box-set TVs defined 1992. Digital cameras arrived on the scene in 1997. And MP3 players, smart phones, and LCD TVs entered homes in 2002, before tablets and e-readers showed up in 2007.
As we accumulated more devices, however, we didn't throw out our old ones. "The living-room television is replaced and gets planted in the kids' room, and suddenly one day, you have a TV in every room of the house," said one researcher. The average number of electronic devices rose from four per household in 1992 to 13 in 2007. We're not just keeping these old devices — we continue to use them. According to the analysis of Babbitt's team, old desktop monitors and box TVs with cathode ray tubes are the worst devices with their energy consumption and contribution to greenhouse gas emissions（排放）more than doubling during the 1992 to 2007 window.
So what's the solution（解决方案）? The team's data only went up to 2007, but the researchers also explored what would happen if consumers replaced old products with new electronics that serve more than one function, such as a tablet for word processing and TV viewing. They found that more on-demand entertainment viewing on tablets instead of TVs and desktop computers could cut energy consumption by 44%.

3 . 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.

| B．Who is stealing your network identity? |
| C．Minority network opinion spread, curse or blessing? |
| D．Have you been misled during the last political voting? |
4 . In our information-driven society, shaping our worldview through the media is similar to forming an opinion about someone solely based on a picture of their foot. While the media might not deliberately deceive us, it often fails to provide a comprehensive view of reality.
Consequently, the question arises: Where, then, shall we get our information from if not from the media? Who can we trust? How about experts- people who devote their working lives to understanding their chosen slice of the world? However, even experts can fall prey to the allure of oversimplification, leading to the “single perspective instinct” that hampers (阻碍) our ability to grasp the intricacies (错综复杂) of the world.
Simple ideas can be appealing because they offer a sense of understanding and certainty. And it is easy to take off down a slippery slope, from one attention-grabbing simple idea to a feeling that this idea beautifully explains, or is the beautiful solution for, lots of other things. The world becomes simple that way.
Yet, when we embrace a singular cause or solution for all problems, we risk oversimplifying complex issues. For instance, championing the concept of equality may lead us to view all problems through the lens of inequality and see resource distribution as the sole panacea. However, such rigidity prevents us from seeing the multidimensional nature of challenges and hinders true comprehension of reality. This “single perspective instinct” ultimately clouds our judgment and restricts our capacity to tackle complex issues effectively. Being always in favor of or always against any particular idea makes you blind to information that doesn’t fit your perspective. This is usually a bad approach if you would like to understand reality.
Instead, constantly test your favorite ideas for weaknesses. Be humble about the extent of your expertise. Be curious about new information that doesn’t fit, and information from other fields. And rather than talking only to people who agree with you, or collecting examples that fit your ideas, consult people who contradict you, disagree with you, and put forward different ideas as a great resource for understanding the world. If this means you don’t have time to form so may opinions, so what?
Wouldn’t you rather have few opinions that are right than many that are wrong?

| B．Simplifying Information: Enhancing Comprehension |
| C．Understanding Differences: Establishing Relationships |
| D．Navigating Complexity: Challenging Oversimplification |
5 . 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.

| 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. |

7 . When you ask people to judge others by their speech, a trend emerges: Listeners dislike disfluency. Slow talkers producing loads of ums and pauses(停顿)are generally perceived as less charming. But science tells us there may be even more to disfluency.
Disfluencies do not occur in arbitrary positions in sentences. Ums typically occur right before more difficult or low-frequency words. Imagine you’re having dinner with a friend at a restaurant,and there’re three items on the table: a knife, a glass, and a wine decanter(醒酒器). Your friend turns to you and says, “Could you hand me the...um...” What would you assume they want? Since it’s unlikely that they will hesitate before such common words as knife, and glass, chances are you’ll pick up the decanter and ask, “You mean this?”
This is exactly what we demonstrated through controlled eye-tracking studies in our lab. Apparently, listeners hear the um and predict that an uncommon word is most likely to follow.Such predictions, though, reflect more than just simple association between disfluencies and difficult words; listeners are actively considering from the speaker’s point of view. For example, when hearing a non-native speaker say the same sentence but with a thick foreign accent, listeners don’t show a preference for looking at low-frequency objects. This is probably because listeners assume non-native speakers may have as much trouble coming up with the English word for a common object, like a knife, as for unusual ones and can’t guess their intention.
In another experiment, listeners were presented with an atypical speaker who produced disfluencies before simple words and never before difficult words. Initially, participants displayed the natural predictive strategy: looking at uncommon objects. However, as more time went by, and they gained experience with this atypical distribution of disfluencies, listeners started to demonstrate the contrary predictive behavior: They tended to look at simple objects when hearing the speaker say um.
These findings represent further evidence that the human brain is a prediction machine: We continuously try to predict what will happen next, even though not all disfluencies are created equal.

8 . “Two centuries ago, Lewis and Clark left St. Louis to explore the new lands acquired in the Louisiana Purchase,” George W. Bush said, announcing his desire for a program to send men and women to Mars. They made that journey in the spirit of discovery. America has ventured forth into space for the same reasons.
Yet there are vital differences between Lewis and Clark’s expedition and a Mars mission. First, they were headed to a place where hundreds of thousands of people were already living. Second, they were certain to discover places and things of immediate value to the new nation. Third, their venture cost next to nothing by today’s standards. A Mars mission may be the single most expensive non-wartime undertaking in U.S. history.
Appealing as the thought of travel to Mars is, it does not mean the journey makes sense, even considering the human calling to explore. And Mars as a destination for people makes absolutely no sense with current technology.
Present systems for getting from Earth’s surface to low-Earth orbit are so fantastically expensive that merely launching the 1,000 tons or so of spacecraft and equipment a Mars mission would require could be accomplished only by cutting health-care benefits, education spending, or other important programs—or by raising taxes. Absent (缺乏)some remarkable discovery, astronauts, geologists, and biologists once on Mars could do little more than analyze rocks and feel awestruck (敬畏的) staring into the sky of another world. Yet rocks can be analyzed by automated probes without risk to human life, and at a tiny portion of the cost of sending people.
It is interesting to note that when President Bush unveiled (公开) his proposal, he listed these recent major achievements of space exploration: pictures of evidence of water on Mars, discovery of more than 100 planets outside our solar system, and study of the soil of Mars. All these accomplishments came from automated probes or automated space telescopes. Bush’s proposal, which calls for reprogramming some of NASA’s present budget into the Mars effort, might actually lead to a reduction in such unmanned science—the one aspect of space exploration that’s working really well.
Rather than spend hundreds of billions of dollars to hurl (投) tons toward Mars using current technology, why not take a decade or two or however much time is required researching new launch systems and advanced propulsion (推进力)? If new launch systems could put weight into orbit affordably, and advanced propulsion could speed up that long, slow transit (运输) to Mars, the dream of stepping onto the red planet might become reality. Mars will still be there when the technology is ready.
1. What do Lewis and Clark’s expedition and a Mars mission have in common?| A．Instant value. | B．Human inhabitance. |
| C．Venture cost. | D．Exploring spirit. |
| A．great achievements have already been made in Mars exploration in America. |
| B．American people’s well-being will suffer a lot if it is carried out. |
| C．its expense is too huge for the government to afford. |
| D．unmanned Mars exploration sounds more practical and economical for the moment. |
| A．Going to Mars using current technology is quite sensible. |
| B．A Mars mission will in turn promote the development of unmanned program. |
| C．Bush’s proposal is based on three recent great achievements of space exploration. |
| D．The achievements in space exploration show how well manned science has developed. |
| A．Risky as it is, a Mars mission helps maintain America’s position as a technological leader. |
| B．A Mars mission is so costly that it may lead to an economic disaster in America. |
| C．Someday people may go to Mars but not until it makes technological sense. |
| D．A Mars mission is unnecessary since the scientists once there won’t make great discoveries. |
9 . How to Feel Connected
It's easy to feel disconnected from what is going on around you in today's fast-paced world.
Consider why you feel disconnected. Knowing what is making you feel disconnected can help you choose the best ways to address it.
Interact with people in person. Technology is a great way to stay in touch, but sometimes you need to spend time with other people in person.
Your loved ones could feel shy, so you may never know how to improve your relationship unless you ask the right questions. Asking them to open the doors can give you some insight on what you can do. Learning this information can help to strengthen your bond.
Show your commitment to them. Simply showing up and being there for your loved ones says a lot about how much you value your relationships. Putting in the time shows them that you are committed and want to stay connected.
Show appreciation. A simple “thank you” goes a very long way. Unfortunately, it is something that people who are close often take for granted. Telling someone you appreciate their time, love, and efforts can strengthen your bond and help you to become more connected.
| A．Ask others what they need from you. |
| B．Sometimes you can feel isolated and distant from the ones you love. |
| C．Be brave to express your love. |
| D．Reach out to people to schedule a time to get together. |
| E．Attending family events, or simply visiting someone once a week can help to strengthen your relationship and keep it strong. |
| F．Targeting your efforts toward those issues allows you to close that distance more effectively. |
| G．You can have a gift delivered to friends on special occasions. |
Jean’s dream was to be a great chef, so when she was 20, she travelled to France, which has the most famous cuisine in the world, to learn to cook. After twelve years, she was among the best.
Her father, Bob, was getting old, and she wanted to be near him. Jean accepted an offer from one of Washington’s top restaurants. The manager offered her a handsome salary, and 30% ownership of the restaurant. The next day, Jean went to sign the contract. As she got out of the car, she caught sight of a green sunshade. Instead of going to meet the manager, she crossed the street towards the old restaurant, Fargonetti’s. She pushed open the door and the memories came flooding back.
Jean’s mum died when she was just 11, and her father lost his job and was forced to freelance (从事自由职业). Money was very short. When Jean turned thirteen, Bob had made a reservation at Fargonetti’s, the capital’s best restaurant.
“I’m not hungry, baby girl. I had a huge breakfast,” Bob said. “This is all for you!” “Oh,” Jean cried. “Daddy was so silly! He’s been saving to come here for lunch for MONTHS and now he ruined his appetite with breakfast!” The waiter, Carl Bader, immediately realised what was going on and went to Mr Fargonetti, the restaurant owner, and told him about Jean and Bob.
An hour later, surprisingly, the waiter brought wonderful dishes and set them before the father and daughter. “Lunch is on the house with Mr Fargoneti’s compliments (致意),” Carl said. For Bob and Jean, it was a free but magical meal. They were on cloud nine when they walked out. “Jean,“ said Bob happily. “I feel our luck has changed!” And it did! The next day, one of Bob’s old friends called and offered him a job at a new magazine, and Jean believed Fargonetti’s had made it all happen. That was when she decided to become a chef!
Twenty years later, the old restaurant looked run-down and sad, but Jean recognised the waiter immediately. “Carl?” she asked delightedly.
