1 . 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.

2 . As a “major” at university, philosophy may not be so popular nowadays, for it seems to be too abstract, remote and impractical, unlike subjects such as computing, finance, accounting and so on.
Fundamentally speaking, the word “philosophy”，originated from the Greek Φιλοσοφία meaning “love of wisdom”, originally included all kinds of knowledge. In that world dominated by supernatural gods, philosophers and scientists were the same, and their wisdom was started by asking questions. They believed that everything in the world is composed of air and attempted to examine the air and the sun --- these quests developed their wisdom.
The relations between man and the world may be divided into three categories, namely the relationships between man and nature, man and society and within the human self, which are studied separately by the natural sciences, such as physics, chemistry, mathematics, biology; social sciences, such as sociology, economics, politics, law, ethics; and sciences of thinking, such as brain science, neuroscience(神经学), psychology, logic. Philosophy, however, is none of these branches of learning but their abstraction and generalization.
The benefits of studying philosophy may be realized as follows: First, it assists people to properly adjust the relations between nature, society and the self, becoming fully aware of where they stand macrocosmically(宏观地)and microcosmically. Second, it makes people think more systematically, combining various “separated materials”. Essentially, philosophy is the study of thinking, analyzing issues from different angles before anything can be taken in. Special attention is paid to strict reflection during every stage of thinking and this process itself is included as part of its study, so as to form a pattern of clear critical thinking. Third, philosophy can also shape one’s character. Difficult thinking, reasoning and summarizing result in people becoming firmer and more persistent in a deep sense. Since philosophy is finally about living, it leads to an appreciation of meaningful life through perfecting personality.
In a sense, philosophy is in fact widely applicable and has been studied and acquired by experts of natural and social sciences and many philosophers, both at home and abroad, who have become celebrities either in their specialist fields of study or in their switched professions as generalists.
Therefore, philosophy is not abstract, nor remote, but of profound use.

3 . 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.

4 . 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.

5 . 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）.

6 . 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. |
7 . 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.

8 . 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."

9 . 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.

| D．Manufacturers’ developing a sustainable hardware economy. |
10 . The outstanding biography — from the same author who brought us Steve Jobs and Einstein — portrays the life of the complicated Renaissance (文艺复兴时期的) artist with details. We come to see da Vinci as not only an inventor of musical instruments and early flying machines, but also a notebook keeper and vegetarian (素食者), who had trouble finishing many of the projects and paintings he started.
Yet what is most thrilling is getting to know da Vinci the scientist. Isaacson explains how loving science and applying the scientific method to observing the world was really what made da Vinci a great artist and, Isaacson argues, a genius.
Da Vinci was fascinated with observing and understanding phenomena in nature, from the proportions of the human body to how the muscles of the lips moved. He wanted to know about everything around him, in minute detail, Isaacson writes. He wondered about questions “most people over the age of ten no longer puzzle about”— for instance, how the tongue of a woodpecker works.
To learn about the world, da Vinci combined his own observations with experimentation. Never formally schooled, “he preferred to induce from experiments rather than deduce from theoretical principles,” Isaacson explains. He recorded his observations, looked for patterns among them, and then tested those patterns through additional observation and experimentation.
“When he became fascinated with the idea that he could invent flying machines, three and a half centuries before the Wright brothers flew the first airplane, he observed various birds and filled notebooks with the function and speed at which their wings flapped. That’s why lsaacson calls da Vinci an exemplar of this scientific method.” He goes on: “Galileo, born 112 years after Leonardo, is usually credited with being the first to develop this kind of approach and is often regarded as the father of modern science,” the historian Fritjof Capra wrote. “There can be no doubt that this honor would have been bestowed (赐予) on Leonardo da Vinci had he published his scientific writings during his lifetime, or had his notebooks been widely studied soon after his death.”
Da Vinci’s emphasis on empirical observation also helped him improve his art. First, he was able to use what he learned from looking at nature to paint and draw. His studies of the body, animals, motion, shadow and light, perspective and proportion helped him better understand what he was seeing in front of him, and render it in art more accurately and finely than anyone else of his time. He also used his observations of nature to make connections among phenomena. A recorder (竖笛) was like a larynx (喉管) in the throat. Here’s Isaacson again: What Leonardo probably began as four distinct elements ended up woven together in a way that illustrates a fundamental theme in his art and science: the interconnectedness of nature, the unity of its patterns, and the similarity between the workings of the human body and those of the earth.
Most importantly, his curiosity-driven explorations, and ability to connect art and science, helped him innovate in his work. They helped him think differently, Isaacson argues. Da Vinci made surprisingly diverse series of discoveries, including conceptualizing the helicopter and solar power and advancing knowledge about everything from the reproductive organs to botany. This genius is also what drew lsaacson to Albert Einstein and Steve Jobs as subjects: They’re all innovators who were inspired by and drew connections between art and science.
“Leonardo da Vinci is the ultimate example of the main theme of my previous biographies: how the ability to make connections across disciplines — arts and sciences, humanities and technology — is a key to innovation, imagination, and genius,” Isaacson writes. And this wonderful book is a reminder, in a time of increasingly narrow specialization and focus, that the methods of Renaissance men like da Vinci are as relevant as ever.
