1 . Albert Einstein’s 1915 masterpiece “The Foundation of the General Theory of Relativity” is the first and still the best introduction to the subject, and I recommend it as such to students. But it probably wouldn’t be publishable in a scientific journal today.
Why not? After all, it would pass with flying colours the tests of correctness and significance. And while popular belief holds that the paper was incomprehensible to its first readers, in fact many papers in theoretical physics are much more difficult.
As the physicist Richard Feynman wrote, “There was a time when the newspapers said that only 12 men understood the theory of relativity. I do believe there might have been a time when only one man did, because he was the only guy who caught on, before he wrote his paper. But after people read the paper a lot understood the theory of relativity in some way or other, certainly more than 12.”
No, the problem is its style. It starts with a leisurely philosophical discussion of space and time and then continues with an exposition of known mathematics. Those two sections, which would be considered extraneous today, take up half the paper. Worse, there are zero citations of previous scientists’ work, nor are there any graphics. Those features might make a paper not even get past the first editors.
A similar process of professionalization has transformed other parts of the scientific landscape. Requests for research time at major observatories or national laboratories are more rigidly structured. And anything involving work with human subjects, or putting instruments in space, involves piles of paperwork.
We see it also in the Regeneron Science Talent Search, the Nobel Prize of high school science competitions. In the early decades of its 78-year history, the winning projects were usually the sort of clever but naive, amateurish efforts one might expect of talented beginners working on their own. Today, polished work coming out of internships(实习) at established laboratories is the norm.
These professionalizing tendencies are a natural consequence of the explosive growth of modern science. Standardization and system make it easier to manage the rapid flow of papers, applications and people. But there are serious downsides. A lot of unproductive effort goes into jumping through bureaucratic hoops(繁文缛节), and outsiders face entry barriers at every turn.
Of course, Einstein would have found his way to meeting modern standards and publishing his results. Its scientific core wouldn’t have changed, but the paper might not be the same taste to read.

2 . We’ve all had the experience of wanting to get a project done but putting it off to a later date. So why do we delay things? Are we built to operate this way sometimes?
These questions are central to my research on goal pursuit (追求). It all starts with a simple choice between working now on a given project and doing anything else. The decision to work on something is driven by how much we value accomplishing the project in that moment — what psychologists call its subjective value. And delay, in psychological terms, is what happens when the value of doing something else outweighs the value of working now.
This way of thinking suggests a simple trick to defeat delay. For example, instead of cleaning my house, I might try to focus on why grading papers is personally important to me. It’s simple advice, but sticking to this strategy (策略) can be quite difficult.
People are not entirely wise in the way they value things. For example, a dollar bill is worth exactly the same today as it is a week from now, but its subjective value — roughly how good it would feel to own a dollar—depends on other factors besides its face value, such as when we receive it. The tendency for people to devalue money and other goods based on time is called delay discounting. For example, receiving $100 three months from now is worth the same to people as receiving $83 right now. People would rather lose $17 than wait a few months to get a larger reward.
Getting something done is a delayed reward, so its value in the present is reduced: the further away the deadline is, the less attractive it seems to work on the project right now. The tendency to delay things closely follows economic models of delay discounting. One way to manage it is to make the finish line seem closer. For example, vividly imagining a future reward reduces delay discounting.

3 . Taste memory is a kind of interesting memory. It is not only the memory of the smell itself, but also the associative memory of the things related to the smell and the emotional memory related to the judgment of the likes and dislikes of the smell. In short, when we smell a familiar smell, our first reaction is to search for the possible source of the smell in our memory - a certain kind of food? Some kind of perfume? Someone? Some place? Even if we smell a strange smell, we will subconsciously look for the smell similar to the smell in our memory.
The particularity of taste is also closely related to our survival instinct - because taste is often associated with food. It is an important survival skill to judge the food's edibility by smell. I have been experimenting with taste aversion(厌恶) memory for a period of time - a taste that has never been encountered and cannot be identified as safe. If there are adverse physiological reactions after eating, I will instinctively avoid this taste the next time I encounter it. This kind of phenomenon will be restrained to a certain extent when it comes to the familiar taste of safety, which is called "potential inhibition", that is, the degree of aversion will be reduced. However, if a person is familiar with the safe taste and has a very serious reaction, this taste will be associated with painful memory, then even if he knows that the taste is safe, he will also involuntarily avoid the food or affect his appetite. This fully shows that taste is not a single memory, but mixed with a large number of other memories.
"People's memory of smell will never be forgotten" - I don't know the origin of this proposition, and it's also too absolute to say that it will never be forgotten - in fact, many diseases lead to people's inability to smell smell, let alone their memory of smell. However, due to the particularity of taste, different taste can not only cause active memory, but also cause a variety of subconscious memory, and also bring a variety of physiological reactions in the body. Therefore, compared with other kinds of memory, it is not easy to forget, which is more reasonable.

4 . We all do it. We put off that dreaded task for five more minutes, then for thirty minutes, then for another hour, until it doesn’t get done at all. And the worst part is we still weren’t able to enjoy our day. We spend so much time stressing over that looming task that it deprives us from actually being able to focus on other tasks.
Why do we do it? We know it never ends well. The problem is that the cycle can feel nearly impossible to break. We get so caught up in the cycle of procrastination that we almost forget how to effectively tackle hard tasks.
Here are five tips for nipping procrastination in the bud and taking back control over your daily life.
Tackle the most difficult task first.
You’re probably thinking “Duh, I already knew that.” But you may not have realized that there’s scientific backing for this suggestion. We only have a limited supply of willpower. Once it’s been used up for the day, chances of us tackling hard tasks are pretty slim. Dive into your hardest task when your energy level is at its highest. This will ensure the best results.
When we push the hard tasks to the end of the day, it takes a toll on our energy all day long. In the end, stressing for hours over the task we’re procrastinating negatively affects all the other tasks on our list.
So next time you’re scheduling the items on your list, make sure to start out with worst one. It may not necessarily be the largest, but it should be the one you’re dreading the most. By accomplishing it so early in the day, you will feel energized and productive. You’ll know the rest of the day is all downhill and cruise through the list with remarkable speed.
Divide the task into smaller tasks.
We tend to get overwhelmed when a giant project looms ahead of us. We don’t know where to start or what to do first. Keep in mind that forests are made up of individual trees. Though you may not be able to take down a whole forest at once, you could certainly start with one tree (or even a branch).
If you need to organize your entire kitchen, start by working on just one cupboard. Organizing one cupboard is much more feasible than trying to get everything done in one swoop. Make a commitment to complete a small step each day, and you’ll find the task becoming less and less daunting with each new task that you accomplish.
Set a mid-day alarm.
There’s nothing more guilt-inducing than ending a day and realizing you haven’t accomplished a single task. We can avoid this rut by setting an alarm on our phone to ring every day around 1 p.m. When the ringer goes off, assess how many things on your list have been attended to.
Re-plan your schedule for the remainder of the afternoon and shift it around to take care of the most important item first. If necessary, you can indulge in a second cup of coffee to jumpstart your “second morning.” By doing this, you will avoid going to bed at night mulling over all the things you didn’t get done.
Dedicate yourself for a small period of time.
To stimulate productivity, there’s an old trick of setting a timer for ten minutes. By frantically racing the clock for that short period, you’ll likely find you become engrossed in your tasks and continue working.
The feeling of dread that has been on your mind will quickly be replaced with a sense of pride and satisfaction. Seeing what you can accomplish in ten minutes when you put your mind to it is quite motivating.
Schedule your tasks on the calendar.
Creating a game plan will help you move past the initial paralysis you feel. Instead of just writing the tasks down in a to-do list, take it a step further and identify when and how you’ll accomplish it.
For example, plan to go to the grocery store at 4:00 p.m. and start cooking dinner promptly at 4:30. By clearing up the anticipatory stress, you’ll avoid a large part of the dread that holds you back. Creating the plan is half the battle!
Though it feels impossible, you have it in you to accomplish everything that you need to every single day. With a fresh perspective, a little prodding (敦促), and a detailed plan, you’ll be well on your way to ending the procrastination cycle once and for all.

5 . When you hear “I have a dream…”, one of the most famous speeches in human history, you’ll never have the idea how the audience on the scene were fueled by emotional intelligence. When Martin Luther King. Jr. presented his dream, he chose language that would stir the hearts of his audience. Delivering this electrifying(震撼性的) message required emotional intelligence—the ability to recognize, understand, and manage emotions.
Emotional intelligence has been highly recommended by leaders, policymakers, and educators as the solution to a wide range of social problems. Emotional intelligence is important, but the uncontrolled enthusiasm has obscured (掩盖)a dark side. New evidence shows that when people sharpen their emotional skills, they become better at controlling others. When you’re good at controlling your own emotions, you can hide your true feelings. When you know what others are feeling, you can motivate them to act against their own best interests.
Social scientists have begun to document this dark side of emotional intelligence. In a research led by University of Toronto professor Jochen Menges, when a leader gave an inspiring speech filled with emotion, the audience was less likely to scrutinize (细察) the message and remembered the content. Ironically(讽刺 的是), audience members were so moved by the speech that they claimed to recall more of it.
The authors call this the awestruck effect, but it might just as easily be described as the dumbstruck effect. One observer reflected that Hitler’s persuasive impact came from his ability to strategically express emotions—he would “tear open his heart”—and these emotions affected his followers to the point that they would “stop thinking critically and just emote.”
Leaders who master emotions can rob us of our abilities to reason. If their values are out of step with our own, the results can be destructive. New evidence suggests that when people have self-serving motives, emotional intelligence becomes a weapon for controlling others.
Throwing light on this dark side of emotional intelligence is one mission of a research team led by University College London professor Martin Kilduff. According to these experts, emotional intelligence helps people disguise (伪装) one set of emotions while expressing another for personal gain. Professor Kilduff’s team writes, “The strategic disguise of one’s own emotions and the controlling of others’ emotions for strategic ends are behaviors evident not only on Shakespeare’s stage but also in the offices and corridors where power and influence are traded.”
Of course, people aren’t always using emotional intelligence for nefarious ends. More often than not, high EQ is helpful in most aspects of our life. Emotional intelligence—like any skill—can be used for good or evil. So whether it is a gift or a curse lies in your hand.

6 . I was given a voice. That’s what people said about me I trained my voice, because it would be a shame to waste such a gift. I pictured this voice as a greenhouse plant and made sure it was provided with the right temperature, the right amount of water. I relieved its fears. I told it not to tremble. I nursed it, I trained it, and I watched it climb up inside my neck
My voice bloomed. People said I had grown into my voice. Invitations to perform flooded over us. All the best places wanted us. I was sought after, or rather my voice was. We went everywhere together and gave performances. Bouquets （花束）were thrown to it. Money was presented to it. Men fell on their knees before it. Applause flew around it.
Then my voice began to shrivel. People said my voice would bloom only for a certain term: finally it would drop off and gone with it would be all the fame and wealth. I have noticed it so far. Fear has entered me since my voice has used up most of my life. I’ve given it all my love. But my voice is still as greedy as ever. It wants more: more and more, more of everything it has had so far.
Now it’s evening: the bright lights come on, and excitement quickens in the streets. We sit in this hotel room. Soon it will be time for us to go out. We have to attend a grand occasion. The two of us chained together as always. I have to put on its favourite dress, its favourite necklace and wind a fur around it. Then I have to go out: shining like ice: my voice attached to my throat like an invisible vampire （吸血鬼）.

7 . Great work is work that makes a difference in people’s lives, writes David Sturt, Executive Vice President of the O.C. Tanner Institute, in his book Great Work: How to Make a Difference People Love. Sturt insists, however, that great work is not just for surgeons or special-needs educators or the founders of organizations trying to eliminate poverty in sub-Saharan Africa. The central theme of Great Work, according to Sturt, is that anyone can make a difference in any job. It’s not the nature of the job, but what you do with the job that counts. As proof, Sturt tells the story of a remarkable hospital cleaner named Moses.
In a building filled with doctors and nurses doing great life-saving work, Moses the cleaner makes a difference. Whenever he enters a room, especially a room with a sick child, he engages both patients and parents with his optimism and calm, introducing himself to the child and, Sturt writes, speaking “little comments about light and sunshine and making things clean.” He comments on any progress he sees day by day (“you’re sitting up today, that’s good.”) Moses is no doctor and doesn’t pretend to be, but he has witnessed hundreds of sick children recovering from painful surgery, and parents take comfort from his encouraging words. For Matt and Mindi, whose son McKay was born with only half of a heart, Moses became a close friend. As Sturt explains, “Moses took his innate (与生俱来的) talents (his sensitivity) and his practical wisdom (from years of hospital experience) and combined them into a powerful form of patient and family support that changed the critical-care experience for Mindi, Matt and little McKay.”
How do people like Moses do great work when so many people just work? That was the central question raised by Sturt and his team at the O.C. Tanner Institute, a consulting company specialized in employee recognition and rewards system.
O.C. Tanner launched an exhaustive Great Work study that included surveys to 200 senior executives, a further set of surveys to 1,000 managers and employees working on projects, an in-depth qualitative study of 1.7 million accounts of award-winning work (in the form of nominations (提名) for awards from corporations around the world), and one-on-one interviews with 200 difference makers. The results of the study revealed that those who do great work refuse to be defeated by the constraints of their jobs and are especially able to reframe their jobs: they don’t view their jobs as a list of tasks and responsibilities but see their jobs as opportunities to make a difference. No matter, as Moses so ably exemplifies (例证), what that job may be.
1. According to Sturt, which of the following is TRUE?| A．It’s not the nature of the job, but what you do that makes a difference. |
| B．Anyone in the world is responsible to delete poverty and change the world. |
| C．Anyone can make a difference in people’s lives no matter what kind of job he does. |
| D．Surgeons, special-needs educators and founders of organizations can succeed more easily. |
| A．By keeping optimistic and calm when facing patients and their parents at hospital. |
| B．By showing his special gift and working experience when working at hospital. |
| C．By showing his sympathy and kindness to patients when entering their rooms. |
| D．By pretending to be a doctor or nurse when entering a room with a sick child. |
| A．demands | B．advantages | C．disadvantages | D．limitations |
| A．Great work is work that makes a difference in people’s lives no matter what you do. |
| B．If a boss has trouble recognizing his employees, he can ask O. C. Tanner for advice. |
| C．Moses makes a difference through his sensitivity and his practical wisdom. |
| D．Those who do great work are never defeated by others or their jobs themselves. |
8 . Modern medicine’s ability to keep us alive makes it tempting to think human evolution may have stopped. But if we look at the rate of our DNA’s evolution, we can see that human evolution hasn’t stopped – it may even be happening faster than before.
Evolution is a gradual change to the DNA of a species over many generations. It can occur by natural selection, when certain traits created by genetic changes help an organism survive or reproduce. Such genes are thus more likely to be passed on to the next generation, so they increase in frequency in a population. Gradually, these changes and their associated traits become more common among the whole group.
By looking at global studies of our DNA, we can see evidence that natural selection has recently made changes and continues to do so. Though modern healthcare disrupts a key driving force of evolution by keeping some people alive longer, in countries without access to good healthcare, populations are continuing to evolve. Survivors of infectious disease outbreaks drive natural selection by giving their genetic resistance to offspring. Our DNA shows evidence for recent selection for resistance of killer diseases like Lassa fever and malaria. Selection in response to malaria remains in regions where the disease remains common.
Humans are also adapting to their environment. Gene change allowing humans to live at high altitudes have become more common in populations in Tibet, Ethiopia, and the Andes. The spread of genetic changes in Tibet is possibly the fastest evolutionary change in humans, occurring over the past 3,000 years. This rapid increase in frequency of a mutated gene that increases blood oxygen content gives locals a survival advantage in higher altitudes, resulting in more surviving children.
Diet is another source for adaptations. Studies show that natural selection favoring a change allowing adults to produce lactase – the enzyme (酶) that breaks down milk sugars – is why some groups of people can digest milk. Over 80 per cent of northwest Europeans can, but in parts of East Asia, where milk is much less commonly drunk, an inability to digest lactose is the norm. Like high altitude adaptation, selection to digest milk has evolved more than once in humans and may be the strongest kind of recent selection.
Yet, despite these changes, natural selection only affects about 8 per cent of our genome. But scientists can’t explain why some genes are evolving much faster than others. We measure the speed of gene evolution by comparing human DNA with that of other species. One fast-evolving gene is human accelerated region 1 (HAR1), which is needed during brain development. A random section of human DNA is on average more than 98 per cent identical to the chimp comparator, but HAR1 is so fast evolving that it’s only around 85 per cent similar. Though scientists can see these changes are happening – and how quickly – we still don’t fully understand why fast evolution happens to some genes but not others.

9 . One morning, when Gregor Samsa woke from troubled dreams, he found himself transformed in his bed into a horrible insect. He lay on his armor-like back, and if he lifted his head a little he could see his brown belly, slightly domed and divided by arches into stiff sections. The bedding was hardly able to cover it and seemed ready to slide off any moment. His many legs, pitifully thin compared with the size of the rest of him, waved about helplessly as he looked.
"What's happened to me?" he thought. It wasn't a dream. His room, a proper human room although a little too small, lay peacefully between its four familiar walls. A collection of textile samples lay spread out on the table—Samsa was a travelling salesman—and above it there hung a picture that he had recently cut out of an illustrated magazine and housed in a nice, gilded frame. It showed a lady fitted out with a fur hat and fur scarf who sat upright, raising a heavy fur muff (暖手筒) that covered the whole of her lower arm towards the viewer.
Gregor then turned to look out the window at the dull weather. Drops of rain could be heard hitting the window, which made him feel quite sad. "How about if I sleep a little bit longer and forget all this nonsense," he thought, but that was something he was unable to do because he was used to sleeping on his right, and in his present state couldn't get into that position. However hard he threw himself onto his right, he always rolled back to where he was. He must have tried it a hundred times, shut his eyes so that he wouldn't have to look at the floundering legs, and only stopped when he began to feel a mild, dull pain there that he had never felt before.
He thought, "What a heavy career it is that I've chosen! Travelling day in and day out. Doing business like this takes much more effort than doing your own business at home, and on top of that there's the curse of travelling, worries about making train connections, bad and irregular food, contact with different people all the time so that you can never get to know anyone or become friendly with them." He felt a slight itch up on his belly; pushed himself slowly up on his back towards the headboard so that he could lift his head better; found where the itch was, and saw that it was covered with lots of little white spots which he didn't know what to make of; and when he tried to feel the place with one of his legs he drew it quickly back because as soon as he touched it he was overcome by a cold tremble.
He slid back into his former position. "Getting up early all the time," he thought, "it makes you stupid. You've got to get enough sleep. Other travelling salesmen live a life of luxury. For instance, whenever I go back to the guest house during the morning to copy out the contract, these gentlemen are always still sitting there eating their breakfasts. I ought to just try that with my boss; I'd get kicked out on the spot. But who knows, maybe that would be the best thing for me. If I didn't have my parents to think about I'd have given in my notice a long time ago, I'd have gone up to the boss and told him just what I think, tell him everything I would, let him know just what I feel. He'd fall right off his desk! And it's a funny sort of business to be sitting up there at your desk, talking down at your inferiors from up there, especially when you have to go right up close because the boss is hard of hearing. Well, there's still some hope; once I've got the money together to pay off my parents' debt to him—another five or six years I suppose—that's definitely what I'll do. That's when I'll make the big change. First of all though, I've got to get up, my train leaves at five."

10 . Hardware in general, and smartphones in particular, have become a huge environmental and health problem in the Global South’s landfill sites(垃圾填埋场).
Electronic waste (e-waste) currently takes up 5 percent of all global waste, and it is set to increase rapidly as more of us own more than one smartphone, laptop and power bank. They end up in places like Agbogbloshie on the outskirts of Ghana’s capital, Accra. It is the biggest e-waste dump in the world, where 10,000 informal workers walk through tons of abandoned goods as part of an informal recycling process. They risk their health searching for the precious metals that are found in abandoned smartphones.
But Agbogbloshie legally should not exist. The Basel Convention, a 1989 treaty, aims to prevent developed nations from unauthorized dumping of e-waste in less developed countries. The e-waste industry, however, circumvents regulation by exporting e-waste labelled as “secondhand goods” to poor countries like Ghana, knowing full well that it is heading for a landfill site.
A recent report found Agbogbloshie contained some of the most dangerous chemicals. This is not surprising: smart phones contain chemicals like mercury(水银), lead and even arsenic(砷). Reportedly, one egg from a free-range chicken in Agbogbloshie contained a certain chemical which can cause cancer and damage the immune system at a level that’s about 220 times greater than a limit set by the European Food Safety Authority (EFSA). Most worryingly, these poisonous chemicals are free to pollute the broader soil and water system. This should concern us all, since some of Ghana’s top exports are cocoa and nuts.
Some governments have started to take responsibility for their consumers’ waste. For example, Germany has started a project that includes a sustainable recycling system at Agbogbloshie, along with a health clinic for workers. However, governments cannot solve the problem alone, as there is an almost limitless consumer demand for hardware, especially when governments’ green policies are focused on issues like climate change.
Only the manufacturers can fix this. A more economically sustainable and politically possible solution is through encouraging hardware manufacturers to make the repair, reuse and recycling of hardware profitable, or at least cost-neutral.
1. What can we infer from Paragraph 2?| A．Electronic waste requires more landfill sites. |
