1 . On a dark night, 11-year-old Joe was playing hide-and-seek with his friends in the backyard when he thought he saw Magellan—a huge housecat. However, when the cat suddenly jumped on his head, Joe found it turned out a young cougar. He backed away from the animal, then turned and ran inside the house.
Cougar encounters like this one are becoming increasingly common in the U.S. Most people assume that’s because cougar populations are growing, or because the big cats are coming into closer contact with the expanding web of human suburbs. But Professor Robert Wielgus at Washington State University argues that poorly designed hunting policies might be causing an increase in cougar-human conflicts.
Wielgus’s research teams have been fitting the big cats with radio collars and monitoring their movements. They find that the cougar population is actually declining rapidly and almost no male cougars are over four years of age. And a study shows that the heavily hunted area has five times as many cougar complaints as the lightly hunted area—even though the density of cougars is about the same in both areas.
Wielgus suspects that hunting policies, which allow older males to be killed to keep cougar populations in check, were the culprit and teenage cougars in the heavily hunted area may be responsible for most of the trouble. To test his theory, he adds two more groups of cougars to the tracking program—one in a heavily hunted area and another in a comparable but lightly hunted area. He concludes that heavy hunting indeed almost wipes out older males and the population structure in the heavily hunted area shifts toward younger animals.
With these findings, Wielgus believes without adults to keep them under control, the disorderly teens are more likely to come into conflict with humans, farm animals and pets.
Wielgus’s ideas don’t sit well with everyone. “Hunting definitely does cause lots of teenage males to flow in, but I don’t yet see solid proof that they are more likely to cause trouble than older cats,” says the University of Montana’s Robinson. “In many cases, the new arrivals have been squeezed out of remote wilderness habitat and forced into areas where they are more likely to encounter humans. I think humans are primarily responsible for all the interaction you see. We’re moving into these areas where cougars and deer are,” according to Alldredge, a researcher at the Colorado Division of Wildlife.
We may not understand what makes 18-year-old males more likely than 48-year-old men to do dangerous things, Wielgus says, but we know that the world would be a different place, if teenagers were in charge.

2 . “NON-FUNGIBLE TOKENS” (NFTs) leapt from the more obscure corners of the internet into the mainstream in March 2021 when Christies, a British auction house, sold a digital work of art for $69m. What it actually flogged was an NFT, a cryptocurrency chit that proves a buyer owns an intangible marker connected to a unique piece of digital art, music or other item. Much like René Magritte’s painting of a pipe that proclaims “this is not a pipe” an NFT is not the thing it represents. Tweets, videos of basketball dunks and even the source code to the world wide web have been sold as NFTs in recent months. From June to September they generated almost $11bn in sales, an eight-fold increase on the previous four months, according to DappRadar, a market tracker. What exactly is an NFT? And why are people spending tens of millions of dollars on them?
An NFT is a record on a cryptocurrency’s blockchain (an immutable ledger（不可篡改的账本） that can record more than just virtual coins) that represents pieces of digital media. Invented a few years ago, it can link not only to art but also to text, videos or bits of code. Promoters of NFTs claim that they solve a thorny（棘手的） problem with digital art: how to own an original. For creators who freely upload their work or sell it as identical copies, the concept of an original is difficult to pin down（确定）. Exclusivity is impossible to enforce when digital files can be shared freely on the internet. But collectors want the cachet that comes with having an exclusive claim on an artwork. This is where NFTs fit in.
To mint（铸币，造币） an NFT, the creator establishes a unique record of the artwork, generally on a website. Then the creator places the record on a blockchain, usually Ethereum’s, which requires a transaction fee known as gas. Possession of a private encryption key associated with the transaction proves ownership. This gives an artist or collector something to sell. An NFT may link to a version of the work, but rarely includes the rights to reproduce or distribute it. That differentiates it from a commercial licensing arrangement, too.
NFTs have myriad（众多的） problems. They often change hands using cryptocurrencies, many of which currently have sky-high valuations, leading to fears of a bubble. Anyone can mint an NFT, since the systems involved are decentralised（去中心化的）, although doing so with someone else’s work could be infringe their copyright. Some artists have already claimed misappropriation of their work.Most NFTs are simply links to images. Unless they have been issued in a certain way to ensure they are tamper-proof（防更改的） these can in theory be meddled with after the sale. The high electricity usage of blockchains—Bitcoin’s is greater than that of Chile—has prompted arguments over whether artists are contributing to climate change by embracing NFTs. And ownership may be difficult to prove in the long term, as web-based records may not last for ever.
Yet NFTs have some value beyond the cryptocurrency hype （加密货币炒作）: artists struggle to make a living when their works can be easily replicated and pirated. NFTs will create new problems in an attempt to solve old ones, but for now many creators and collectors are too busy cashing in to care.

3 . Road trip stories are basically wild adventures of self-discovery. But the book Me (Moth) carves out a path through ancestry (祖先), pains and art.
Moth is a dancer with a loving, supportive family - until a terrible car accident takes them all away. Now she doesn't dance any more and lives with her sad aunt, wearing borrowed clothes and living on what feels like borrowed time, because not even the wisdom and Hoodoo (扶都教) passed down to her by her grandfather can bring back her family or ease her pain. Her survivor's guilt is so strong that she makes herself almost invisible.
Until the new boy at school, Sani, notices her. He sings when he thinks no one is listening and he sees Moth like no one else does. The two young people decide on a road trip across the country and hope to make some sense of their life on the way.
Novels in poetic language can sometimes feel awkward, but the book, Me (Moth) spills effortlessly across the page, becoming the song that Moth and Sani write together on their journey. It's all in Moth's voice, and her words dance, giving the reader a real sense of how she can move her body if she isn't afraid to. The language is sometimes so beautiful and terrible that it catches me off guard.
During their trip to the South, Moth and Sani stop to pay respect to the spirits of those who came before them, and to think about their strengths as well as the pains that they've suffered. As they do so, their own strengths and pains are connected with the ones that came before.

4 . Language as a System of Symbols (符号)
Of all systems of symbols, language is the most highly developed. It has been pointed out that human beings, by agreement, can make anything stand for anything. Human beings have agreed, in the course of centuries of mutual dependency, to let the various noises that they can produce with their lungs, throats, tongues, teeth, and lips systematically stand for certain happenings in their nervous systems. We call that system of agreements language.
There is no necessary connection between the symbol and that which it stands for. Just as social positions can be symbolized by feathers worn on the head, by gold on the watch chain, or by a thousand other things according to the culture we live in, so the fact of being hungry can be symbolized by a thousand different noises according to the culture we live in.
However obvious these facts may appear at first glance, they are actually not so obvious as they seem except when we take special pains to think about the subject. Symbols and the things they stand for are independent of each other, yet we all have a way of feeling as if, and sometimes acting as if, there were necessary connections. For example, there are people who feel that foreign languages are unreasonable by nature; foreigners have such funny names for things, and why can’t they call things by their right names? This feeling exhibits itself most strongly in those English and American tourists who seem to believe that they can make the natives of any country understand English if they shout loud enough. Like the little boy who is reported to have said, “Pigs are called pigs because they are such dirty animals, ” they feel that the symbol is inherently connected in some way with the things symbolized.

5 . University educators largely think highly of the wonders of teaching through technology, but skeptics question whether something is lost when professors and lectures rely too heavily on electronic media or when interaction with students takes place remotely — in cyberspace rather than the real space of the classroom. Hans Ulrich Gumbrecht, the Professor of Literature at Stanford University, is one such skeptic. “I think this enthusiastic and sometimes childish and blind pushing toward the more technology the better, the more websites the better teacher, and so forth, is very dangerous — is, indeed, suicidal,” he indicates.
However, Gumbrecht warns that there are few, if any, studies either supporting or rejecting the hypothesis that traditional ways of teaching are superior to teaching via the Internet. He says that he could point only to his “intuition that real classroom presence should be maintained,” and emphasizes the need for educators to examine critically where technology serves a useful pedagogical (教学法的) function and where it does not.
Yet, Gumbrecht allows that, for courses in which knowledge transmission is the sole purpose, electronic media probably can do the job well enough. Indeed, given the 20th century’s knowledge explosion and the increasing costs of higher education, using technology as opposed to real-life teachers for the transmission of information is probably inevitable, he admits. In any case, knowledge transmission should not be the core function of the university, he maintains, noting that universities should be places where people confront open questions, places for “intellectual complexity” and “riskful thinking”.
“We are not about finding or transmitting solutions; we are not about recipes; we are not about making intellectual life easy. Confrontation with complexity is what expands your mind. It is something like intellectual gymnastics. And this is what makes you a suitable member of the society.”
Moreover, discussions in the physical presence of others can lead to the intellectual innovation. “There’s a qualitative change, and you don’t know how it happens. Discussions in the physical presence have the capacity of being the catalyst (催化剂) for such intellectual breakthroughs. The possibility of in-classroom teaching — of letting something happen which cannot happen if you teach by the transmission of information — is a strength.”

6 . The history of microbiology begins with Dutch cloth maker named Antoni van Leeuwenhoek, a man of no formal scientific education. In the late 1600s. Leeuwenhoek, inspired by the magnifying lenses（放大镜）he used to examine cloth, built some of the first-microscopes. He developed technique to improve the quality of tiny, rounded lenses, some of which could magnify an object up to 270 times. After removing some plaque from between his teeth and examining it under a lens, Leeuwenhoek found tiny twisting creatures, which he called “animalcules”.
His observations, which he reported to the Royal Society of London, are among the first descriptions of microbes（微生物）. Leeuwenhoek discovered an entire universe invisible to the human eye. He found different microbes in samples of pond water, rain water, and human blood. He gave the first description of red blood cells, observed plant tissue, examined muscle, and investigated the life cycle of insects.
Nearly two hundred years later, Leeuwenhock’s discovery of microbes helped French chemist and biologist Louis Pasteur to develop his “theory of disease”. This concept suggested that disease originates from tiny organisms attacking and weakening the body. Pasteur’s theory later helped doctors to fight infectious diseases including anthrax, diphtheria, polio, smallpox, tetanus, and typhoid. All these breakthroughs were the result of Leeuwenhoek’s original work. Leeuwenhoek did not foresee this legacy.
In a 1716 letter, he described his contribution to science this way: “My work, which I’ve done for a long time, was not pursued in order to gain the praise I now enjoy, but chiefly from a strong desire for knowledge, which I notice resides in me more than in most other men. And therefore; whenever I found out anything remarkable, I have thought it my duty to put down my discovery on paper, so that the scientific community might be informed thereof.”

7 . 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.

8 . It is an honor for me to deliver this speech and on behalf of the graduating students, welcome you to this special ceremony 2020.
This is a unique moment. We are stepping up to another phase of our lives at a time of great hardship and global difficulties. Hope this ceremony will help erase sad memories, refresh beautiful ones and add more splendid memories into our lives.
I was born in the middle of war, which caused my family to move to Serbia for three years. When the war ended, we returned to Bosnia. My mother, who is and will ever be my heroine, was the only figure who guided me, provided for me and kept me on the right track, in the hope for a better life. I owed her so much as she is responsible for huge part of my success. I will always remember her teachings “to complain less and always find solutions at the price of whatever it takes” ， which brought me to China, an ancient land of new hopes.
During the COVID-19 outbreak, I got the best opportunity to understand China. I saw millions of people united with one goal-to win the battle against this epidemic. I have never seen such a collective dedication from a nation, turning things for the better by sacrificing personal convenience on a grand scale. China's governance and health care system proves to be one of the most efficient in the world. With a population of 1.4 billion, China not only has successfully controlled the transmission of the corona-virus but also assisted many other countries across the globe.
Everyone has a role to play in the battle against the virus. In Tsinghua, I played a tiny but necessary role: Staying on campus, studying online, cooperating during temperature checks and respecting social distancing measures. The rules set by the university and Chinese government had everyone's health and safety as first priority. This made me feel safe and confident that China was on the right track towards victory. Throughout this time, despite the immense challenges, Tsinghua has facilitated many online conferences, which helped me nurture more skills in my field of study.
Friends, we are now graduating from one of the world’s most prestigious universities. Tsinghua has been like a mother to us over the past months and years, guiding and nurturing us along the way, providing us with great vision and placing on us high expectations. So what comes next? Actions speak louder than words. Let us accept new challenges, think beyond our limits and keep in mind the ethics of life.
Let's undertake everything we can for the sake of unity, humanity and the international community. Let's work together for a more promising future and prosperous world.

9 . 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.

10 . 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）.
