1 . Sandhya Sriram is impatient. The stem-cell (干细胞) scientist wanted to put her knowledge to use, developing cultivated seafood. Yet no one was doing that in Singapore. So four years ago, she set up a company to create lab-grown crustacean (甲壳纲动物) meat.
Today, the results of her
Shiok Meats has already revealed shrimp, lobster, and crab prototypes (最初形态) to a select group of tasters, and it plans to
But even if that ambitious
“We’re at an interesting stage of a startup; it’s called the Valley of Death,” says Sriram. “We are in the space where we haven’t submitted for regulatory approval yet, but we’re looking to commercialize in the next two years.” Nevertheless, the impatient entrepreneur is
In a word, when science meets seafood, many wonderful things happen naturally.

2 . Mathematics has an image problem: far too many people are put off by it and conclude that the subject just isn’t for them. But one of the biggest problems is how maths is
I have a different approach which is to relate abstract maths to questions of politics and social justice. I have taught fairly maths-phobic (恐惧) art students in this way and have seen their attitudes
At a basic level, maths is founded on logic, so when I am teaching logic, I use examples from
But I do this with specific mathematical structures, too.
My approach is controversial because, traditionally, maths is supposed to be

6 . One summer night in a seaside cottage, a boy felt himself lifted from bed. Then, with the swiftness of a dream, he was held in his father’s arms out onto the nearby beach. Overhead the sky blazed with stars. “Watch!” Incredibly, as his father spoke, one of the stars moved. In a line of golden fire it flashed across the astonished heavens. And before the wonder of this could fade, another star leaped from its place, then another, plunging towards the restless sea.
“What’s this?” the child whispered.
“Shooting stars. They come every year on a certain August night. I thought you’d like to see the show.”
That was all: just an unexpected glimpse of something mysterious and beautiful. But, back in bed, the child stared for a long time into the dark, knowing that all around the quiet house, the night was full of the silent music of the falling stars.
Decades have passed, but I remember that night still, because I was the fortunate boy whose father believed that a new experience was more important for a small boy than an unbroken night’s sleep. No doubt I had all the usual childhood entertainment, but those are forgotten now. What I remember is the night of the shooting stars, and the day we rode in a caboose (列车末尾的职工车厢), the telegraph we made that really worked, and the “trophy table” in the dining room where we children were encouraged to exhibit things we had found — anything unusual or beautiful — snake skins, seashells, flowers, arrowheads... I remember the thought-provoking (引人深思的) books left by my bedside that pushed back my horizons and sometimes actually changed my life.
My father had, to a marvellous degree, the gift of opening doors for his children, of leading them into areas of splendid newness. This subtle art of adding dimensions to a child’s world doesn’t necessarily require a great deal of time. It simply involves doing things more often with our children instead of for them or to them.

7 . The number of American seniors is growing more quickly than any other portion of the population.
This is, of course, good news. However, an aging population has needs that are not being met. One of these needs is public transportation.
American’s older citizens require increased mobility. With better public transportation, seniors would have more options when choosing where to live. They would also have more choices when deciding how and where they would like to travel.
According to the U.S. Census Bureau, more than 35 million Americans were 65 years old or older on the year 2000. Because there was a baby boom-an increase in births-between 1946 and 1964, the senior population in America will grow much faster than the rest of the population. Many older people already live in suburban locations that lack transit options, and as the baby boomers age, the number of older citizens who live in these areas will continue to increase.
Many people think that the answer to helping mobility for an aging population is simple. They believe that public transportation systems must be upgraded and expanded so that seniors have the resources available to meet their transportation needs.
| A．Better transportation could help America’s senior citizens lead more activities. |
| B．Better public transportation system must be changed in no time to make the senior citizens’ dream come true. |
| C．Better eating habits, more exercise, and advances in medical care are helping American live longer and healthier lives. |
| D．Isolation is a growing problem for elderly Americans. |
| E．Travelling by car should not be a Senior citizens’ only position. |
| F．Mobility plays an important role in the elderly people’s life. |

Ronaldo Luiz Nazario de Lima was born on 22 September 1976 in a poor suburb of Rio de Janeiro. Like most of his childhood friends, Ronaldo began his football (soccer) career playing barefoot in the streets of his neighbourhood. At the age of 14, he joined Sao Cristovao football club and only two years later became the star of Cruzeiro Esporte Clube in Belo Horizonte

10 . A baby born today will be thirty-something in 2050. If all goes well, that baby will still be around in 2100, and might even be an active citizen of the 22nd century. What should we teach that baby to help them survive and flourish in the world of 2050 and beyond? What kind of skills will they need in order to get a job, understand what is happening around them, and navigate their tough life?
At present, too many schools across the world focus on providing pupils with a set of predetermined skills, such as writing computer code in C++ and conversing in Chinese. Yet since we have no idea how the world and the job market will look in 2050, we don’t really know what particular skills people will need. We might invest a lot of effort in teaching kids how to write in C++ or to speak Chinese, only to discover sooner or later that AI will have been able to code software far better than humans, and that a new translation app will have enabled you to conduct a conversation in almost flawless Mandarin, Cantonese or Hakka, even though you only know how to say ni hao.
So what should we be teaching? Many experts argue that schools should downplay technical skills and emphasize general-purpose life skills: the ability to deal with change, to learn new things, and to preserve your mental balance in unfamiliar situations. In order to keep up with the world of 2050, you will above all need to reinvent yourself again and again.
To succeed in such a demanding task, you will need to work very hard on getting to know your operating system better—to know what you are and what you want from life. This is, of course, the oldest advice in the book: know thyself. This advice was never more urgent than in the mid-21st century, because unlike in the days of Laozi or Socrates, now you have serious competition. Coca-Cola, Amazon and Facebook are all racing to hack you.
Right now, the algorithms (算法) are watching where you go, what you buy, and who you meet. Soon they will monitor all your steps, breaths and heartbeats. They are relying on big data and machine learning to get to know you better and better. And once these algorithms know you better than you know yourself, they could control and manipulate (操纵) you. In the end, authority will shift to them.
Of course, you might be perfectly happy giving up all authority to the algorithms and trusting them to make decisions for you and for the rest of the world. If, however, you want to maintain some control over your personal existence and over the future of life in general, you have to run faster than the algorithms. To run fast, don’t take much luggage with you. Leave all your illusions (幻想) behind. They are very heavy.
