2 . American mathematician Dennis Sullivan has been awarded the 2022 Abel Prize, one of the most distinguished awards in math, for his contributions to the fields of topology and dynamical systems. Sullivan has been recognized for his groundbreaking contributions to topology in its broadest sense, and particularly its algebraic (代数的), geometric and dynamical aspects.
Topology is the study of properties of objects and spaces that do not change when they are deformed (变形). The field is sometimes called “rubber-sheet geometry”, because objects can be stretched into different shapes like rubber but cannot be broken. For instance, a square can be deformed into a circle without breaking, but a doughnut shape cannot.
Sullivan, born in Port Huron, Michigan, in 1941, began studying topology as a graduate student at Princeton University in the early 1960s. His 1966 doctoral thesis, called “Triangulating Homotopy Equivalences,” helped revolutionize the study of manifolds, spaces that look flat when viewed from any point on their surface but have a more complicated overall structure.
Subsequently Sullivan taught at several other universities. During this time, he gradually changed how mathematicians perceived algebraic and geometric topology, introducing new ideas and building a new vocabulary. In 1970, he wrote a set of unpublished notes widely circulated and considered hugely influential.
By the late 1970s, Sullivan began investigating problems in dynamical systems, which is the study of a point moving through a geometrical space and a fundamental part of chaos theory. His work united dynamical systems and algebraic topology in ways that had never been done. In 1985, Sullivan proved a 60-year-old assumption that points moving in complex dynamical systems eventually return to their starting point rather than wandering about endlessly.
“Dennis P. Sullivan has repeatedly changed the landscape of topology by introducing new concepts”, said Hans Munthe-Kaas, chair of the Abel Committee. “I’m not sure Sullivan sees the boundaries between different areas of mathematics the same as other people see it.”

5 . It’s a joyful and stressful time of year in the United States for students and their families as they make decisions about where to attend college. Families often turn to rankings systems to help make a decision.
When I talk to families as a scholar of higher education, they’re often surprised that teaching excellence is not counted in rankings.
Emerging research suggests that courses in lower-ranked universities, on average, scored higher on teaching than courses in higher-ranked universities.
Rankings, however, are only one reason why a low value is placed on teaching in higher education. Administrators often don’t view teaching excellence as a way to increase enrolment (注册) or funding.
What should students and their families do? They should give strong consideration to universities where high-quality teaching is valued, even though the schools may be ranked lower.
A.Higher education has achieved its true potential. |
B.Therefore, it’s not highly valued in hiring or promotion. |
C.Quality teaching has been an important reputation-building factor. |
D.However, the rankings ignore a critical factor: the quality of teaching. |
E.Efforts to improve teaching at the university level have recently emerged. |
F.They’re even more surprised at how teaching is undervalued by universities. |
G.In fact, universities often shift emphasis from teaching to other ranking factors. |
6 . Sitting in the garden for my friend’s birthday. I felt a buzz (振动) in my pocket. My heart raced when I saw the email sender’s name. The email started off: “Dear Mr Green, thank you for your interest” and “the review process took longer than expected.” It ended with “We are sorry to inform you…” and my vision blurred (模糊). The position—measuring soil quality in the Sahara Desert as part of an undergraduate research programme — had felt like the answer I had spent years looking for.
I had put so much time and emotional energy into applying, and I thought the rejection meant the end of the road for my science career.
So I was shocked when, not long after the email, Professor Mary Devon, who was running the programme, invited me to observe the work being done in her lab. I jumped at the chance, and a few weeks later I was equally shocked—and overjoyed—when she invited me to talk with her about potential projects I could pursue in her lab. What she proposed didn’t seem as exciting as the original project I had applied to, but I was going to give it my all.
I found myself working with a robotics professor on techniques for collecting data from the desert remotely. That project, which I could complete from my sofa instead of in the burning heat of the desert, not only survived the lockdown but worked where traditional methods didn’t. In the end, I had a new scientific interest to pursue.
When I applied to graduate school, I found three programmes promising to allow me to follow my desired research direction. And I applied with the same anxious excitement as before. When I was rejected from one that had seemed like a perfect fit, it was undoubtedly difficult. But this time I had the perspective (视角) to keep it from sending me into panic. It helped that in the end I was accepted into one of the other programmes I was also excited about.
Rather than setting plans in stone, I’ve learned that sometimes I need to take the opportunities that are offered, even if they don’t sound perfect at the time, and make the most of them.

8 . William Lindesay, renowned Great Wall expert and conservationist, and his wife Wu Qi have traveled across the globe by the back paths, providing their sons Jimmy and Tommy a unique environment for personal growth.
Sunhats, backpacks, sneakers and trekking poles — these are the day-to-day must-haves of the family. This East-meets-West couple started traveling while their younger son was still in nappies in 2003. Most of their trips, most of which are far from the hot spots recommended by travel guidebooks, seem more rigorous than leisurely — heritage study in the Mongolian deserts, a 53-kilometer hiking tour of New Zealand, a one-day climb of three English summits and a six-day train ride from Beijing to Moscow.
“Real travel may be hard, uncertain, uncomfortable, but there’s a feel-good factor when you pass a test of some kind,” Lindesay wrote in the family’s newly published travel memoir Pages of Discovery.
Lindesay attaches great importance to learning out of the classroom, saying that children might score well on school tests, but that experience of the world outside, in distant lands, with different languages, scripts, political structures, and religious beliefs, is the real testing ground.
Children in this international family did not have the same pressure to perform on school tests, but they had “homework” on the road. Wu asked her sons to write travel diaries, collect tickets, draw maps and summarize travel tips. She says such habits, though they might not directly improve test scores, will pay dividends in later life.
These experiences certainly shaped their sons’ characters and influenced their chosen study at university. One read world history, the other international relations. The two brothers also share an interest in historical monuments, and the Great Wall in particular. They are now planning to follow in their father’s footsteps with a new 4,500-km hike on the Great Wall.
“My parents view the world as a big classroom, and my brother and I are the biggest beneficiaries,” Jimmy says.

10 . An Excerpt from The Mexican
—by Jack London
A mysterious youth came to the America—based Mexican Revolutionary Committee, requesting for its admission.
Nobody knew his history. The first day he drifted into their busy rooms, they all suspected him of being a spy of the Diaz regime(迪亚兹政权), which had been carrying out the dictatorial rule since 1876.
Boy as he was, he announced that he was Felipe Rivera, and he wished to work for the revolution. The revolutionists looked at each other with doubt in their eyes. And what made revolutionists the most confused was Rivera’s whereabouts—he always came back with his arms or legs seriously injured, dressed in ragged clothes. So what had he been doing recently? Everyone in the Revolutionary Committee started to take precautions against him.
The situation changed totally when the Committee was in bad need of funds. Much to their surprise, such a slender boy should have successively brought them batches of gold and silver coins. Then came the most urgent situation where 5, 000 dollars were needed to buy guns for those revolutionists on standby on the border between the US and the Mexico. Rivera stood out and made a promise that he would give them 5,000 dollars within three weeks.
So, how could he get so much money within such a short period of time?
Rivera was determined to help his people at the cost of his life. He fought against stronger and tougher boxers in the ring to make money for his people. One day he was engaged in a very tough fight against a champion boxer, Danny. Rivera didn’t match Danny in height, weight, or skills. And he was not half as popular. However, “The winner takes all!” And Rivera stubbornly asked for all—all he had on his mind was making the money for his people.
The fight was going on and on. The whole stadium was cheering for Danny; there were few on Rivera’s side. However, Rivera survived one blow after another; his excellent defence was frightening.
Danny rushed, forcing Rivera to give him a clinch. Was it a trick? Rivera thought to himself.
Yes, it was. But Rivera was smart enough to avoid it. He backed and circled away.
He pretended to clinch with Danny’s next rush. Instead, at the last instant, just as their bodies should have come together, Rivera went quickly back. He had fooled him!
While Rivera was dancing away, Danny kept challenging him openly. Having run after him for two rounds, Danny found the boy not even daring to come near him. He started to throw all caution to the winds. Rivera was struck again and again. He took blows by the dozen—just to avoid the deadly clinch.
In the seventeenth round, Rivera, hit heavily, bent down. His hands dropped helplessly. Danny thought it was his chance—the boy was at his mercy. He decided to strike the deadly blow. But before he could do that, Rivera caught him off his guard and hit him in the mouth. Danny went down. When he rose, Rivera gave him another blow on the neck and jaw. He repeated this three times.
Danny did not rise again. The audience shouted for him to stand up. But the miracle did not happen.
“Count!” Rivera cried to the referee. When the count was finished, Danny, gathered up by his assistants, was carried to his corner.
“Who wins?” Rivera demanded.
Unwillingly, the referee caught his gloved hand and held it high up.
Rivera, unattended, walked to his corner, where his assistants had not yet placed his stool. He didn’t care. All he could remember was that he had got the $5,000 he needed. “The winner takes all! ” What mattered to him was that________.
