1 . Last week, I sent the same request to ChatGPT, the latest artificial-intelligence chatbot from OpenAI. “Upon the Firth of Forth, a bridge doth stand,” it began. In less than a minute, the program had created in full a rhyming Shakespearean sonnet (莎士比亚十四行诗). Tools like ChatGPT seem poised to change the world of poetry — and so much else — but poets also have a lot to teach us about artificial intelligence. If algorithms (算法) are getting good at writing poetry, it’s partially because poetry was always an algorithmic business.
Even the most rebellious (叛逆的) poets follow more rules than they might like to admit. When schoolchildren are taught to imitate the structure of sonnet, they are effectively learning to follow algorithmic constraints. Should it surprise us that computers can do so, too?
But considering how ChatGPT works, its ability to follow the rules for sonnets seems a little more impressive. No one taught it these rules. It is based on a newer kind of AI known as a large language model (LLM). To put it simply, LLMs analyze large amounts of human writing and learn to predict what the next word in a string of text should be, based on context. One frequent criticism of LLMs is that they do not understand what they write; they just do a great job of guessing the next word.
When a private verse by Dickinson makes us feel like the poet speaks directly to us, we are experiencing the effects of a technology called language. Poems are made of paper and ink — or, these days, electricity and light. There is no one “inside” a Dickinson poem any more than one by ChatGPT. Of course, every Dickinson poem reflects her intention to create meaning. When ChatGPT puts words together, it does not intend anything. Some argue that writings by LLMs therefore have no meaning, only the appearance of it. If I see a cloud in the sky that looks like a giraffe, I recognize it as an accidental similarity. In the same way, this argument goes, we should regard the writings of ChatGPT as merely imitating real language, meaningless and random as cloud shapes.
When I showed my friends the sonnet by ChatGPT, they called it “soulless and barren.” Despite following all the rules for sonnets, the poem is predictable. But is the average sonnet by a human any better? If we now expect computers to write not just poems but good poems, then we have set a much higher bar.

2 . On March 7, 1907, the English statistician Francis Galton published a paper which illustrated what has come to be known as the “wisdom of crowds” effect. The experiment of estimation he conducted showed that in some cases, the average of a large number of independent estimates could be quite accurate.
This effect capitalizes on the fact that when people make errors, those errors aren’t always the same. Some people will tend to overestimate, and some to underestimate. When enough of these errors are averaged together, they cancel each other out, resulting in a more accurate estimate. If people are similar and tend to make the same errors, then their errors won’t cancel each other out. In more technical terms, the wisdom of crowds requires that people’s estimates be independent. If for whatever reasons, people’s errors become correlated or dependent, the accuracy of the estimate will go down.
But a new study led by Joaquin Navajas offered an interesting twist (转折) on this classic phenomenon. The key finding of the study was that when crowds were further divided into smaller groups that were allowed to have a discussion, the averages from these groups were more accurate than those from an equal number of independent individuals. For instance, the average obtained from the estimates of four discussion groups of five was significantly more accurate than the average obtained from 20 independent individuals.
In a follow-up study with 100 university students, the researchers tried to get a better sense of what the group members actually did in their discussion. Did they tend to go with those most confident about their estimates? Did they follow those least willing to change their minds? This happened some of the time, but it wasn’t the dominant response. Most frequently, the groups reported that they “shared arguments and reasoned together”. Somehow, these arguments and reasoning resulted in a global reduction in error. Although the studies led by Navajas have limitations and many questions remain, the potential implications for group discussion and decision-making are enormous.

3 . A huge crowd has gathered to watch China’s new scientific research ship enter the water for the first time. This ship, equipped with on-board labs and the latest scientific kit, will eventually explore the world’s oceans. But it is also going to help China plunge beneath the waves: it will serve as a launch-pad for submarines that can dive to the deepest parts of the ocean. “Humans know much less about the deep oceans than we know about the surface of the Moon and Mars. That’s why I want to develop the facility for ocean scientists to reach the deep seas,” says Prof. Cui Weicheng.
He is the dean of deep sea science at Shanghai Ocean University but he has also set up a private company called Rainbow Fish, which built the new research ship and is busy developing submersibles. One of its unmanned subs reached a depth of 4,000m (13,000ft) in its most recent trial. But Rainbow Fish’s ultimate goal is manned exploration and it plans to take humans to the very bottom of the ocean the Mariana Trench, in the Pacific, at a depth of nearly 11,000m (36,000ft). He shows me around a life-size model of the submarine and explains that there is room inside for a crew of three, who will be protected by a thick metal sphere.”At the moment, we are in the design stage, so we are testing several extremely high-strength materials for it.” It will have to bear immense pressures from the crushing weight of water above. If there are any weaknesses, the submarine will implode. The deepest ocean is a place few people have ever experienced first-hand. The first dive to the Mariana Trench was carried out in 1960 by US Navy Lieutenant Don Walsh and Swiss engineer Jacques Picard. Their vessel, the Bathyscaphe Trieste, creaked and groaned as it made the descent, taking nearly five hours.
The only other manned expedition was carried out by Hollywood director James Cameron, who took a solo plunge in a bright green submarine in 2012. Rainbow Fish wants its sub to be next. The team insists its venture isn’t about politics and that it is looking to collaborate with American, Russian and European scientists. It is, though, a commercial operation. The company plans to charge people to use its research ship and submarines, and is targeting three groups, says managing director Dr. Wu Xin. “The first is definitely the scientists who are interested in studying deep-sea science and technology. The second group is offshore companies and oil companies. The last one is tourists and adventurers [who] want to go down themselves to have a look at what’s going on there,” he says. This kind of entrepreneurial approach may be a new model for science in China. Deep-sea research is a difficult, high-risk activity — and much of the ocean remains unexplored. But Cui, who hopes to be the first Chinese person to reach the Mariana Trench, believes that China could be the nation to truly open up this final frontier.

4 . “I’m not a reader.” It’s a common reply that Julia Torres, a teacher-librarian in Denver Public School, has heard throughout her 16-year career. She’s seen students tear up books, throw them away or check them out only to immediately return them all because they didn’t have confidence in their ability to read.
As a librarian, Torres feels strongly that libraries should be spaces of liberation, places where students can develop a love of reading at any stage. Reading is a skill that everyone can grow to love, but too many negative experiences during a child’s literacy (读写能力) education can result in boredom, lack of interest or even anger. When a student has a poor experience like being shamed for their reading choices, they can begin to associate reading with painful feelings of insecurity, shame and stress.
To prevent reading disorder (阅读障碍) practices, as Torres notes, librarians first can build an inclusive (内容丰富的) library where classified collections can make it easier for students to find out the books they want and also help identify gaps in the collections. Reevaluating librarians’ role is necessary, which allows students to take control of the library and have a say in what’s purchased for the collection, directly exciting students’ reading interest. Instead of hosting traditional book fairs where students have to pay for books, it is better to open up a True Book Fair, where students are invited to choose books intentionally to their interests without any costs. Librarians are recommended to read what students are reading. Another two important approaches to preventing reading disorder are to take a look at the library policies and redefine (重新定义) what counts as reading. It is necessary to get rid of fines, check-out limits, security gates, and punishment policies. Plus, students are encouraged to listen to audiobooks or read picture books. Find a way to teach important skills like comprehension or critical thinking with the texts that excite and interest students.

5 . Self-esteem is the ruling view you have of yourself. This includes your beliefs about your inner qualities and how you think others see you.
People with healthy self-esteem don't need to boast about themselves to others. People with low self-esteem may tell you how much everyone loves them, what a great job they do at work, and how amazing they are at pretty everything under the sun even though they really wonder if it's true. People may see them as obnoxious or “full of themselves”.
If you're starting to think you may have low self-esteem, you can work on the way you talk to yourself. When you turn off negative self-talk, you can open the floor to positive reinforcements and access the courage to show different sides of yourself. It isn't going to feel good at first, though. Keep going until it becomes less and less and maybe even a few awkward laughs in the mirror may help.
However, in serious cases of low or even non-existent self-esteem, you may want to call in a professional or a specialist. Good mental health is important, and professionals doing psychotherapy do not pass judgement or give corrections.
A.Self-esteem is not always rooted in reality, though. |
B.You have the power to shape a new self-perception. |
C.This encourages you to speak openly without worry. |
D.The real test of character is whether they can learn from their mistakes. |
E.Self-esteem refers to a person's overall sense of his or her value or worth. |
F.People with a healthy level of self-esteem present themselves with a casual confidence. |
G.With some practice and persistence, you will win this internal struggle to see your self-worth. |
6 . Neuro-technology has long been a favourite of science-fiction writers. In “Neuromancer”, a wildly inventive book by William Gibson written in 1984, people can use neural(神经的) implants to get into the sensory experiences of others. Iain M. Banks came up with the idea of a neural lace, a mesh (网格) that grows into the brain, in his “Culture” series of novels. “The Terminal Man” by Michael Crichton, published in 1972, imagines the effects of a brain implant on someone who is convinced that machines are taking over from humans.
Where the sci-fi led, philosophers are now starting to follow. In Howard Chizeck’s lab at the University of Washington, researchers are working on an implanted device to administer deep-brain stimulation (DBS) in order to treat a common movement disorder called essential tremor. Traditionally, DBS stimulation is always on, wasting energy and robbing the patient of a sense of control. The lab’s ethicist (伦理学家), Tim Brown, a doctoral student of philosophy, says that some DBS patients suffer a sense of isolation and complain of feeling like a robot.
To change that, the team at the University of Washington is using neuronal activity associated with intentional movements to turn the device on. But the researchers also want to enable patients to use a conscious thought process to override these settings. That is more useful than it might sound: stimulation currents for essential tremor can cause side-effects like distorted (失真的) speech, so someone about to give a presentation, say, might wish to shake rather than make his words unclear. Giving humans more options of this sort will be essential if some of the more advanced visions for brain-computer interfaces are to be realized. Hannah Maslen from the University of Oxford is another ethicist who works on a BCI project. One of her jobs is to think through the distinctions between inner speech and public speech: people need a dependable mechanism for separating what they want to say from what they think.
That is only one of many ethical questions that the sci-fi versions of brain-computer interfaces bring up. What protection will BCIs offer against neural hacking? Who owns neural data, including information that is gathered for research purposes now but may be understandable in detail at some point in the future? Where does accountability lie if a user does something wrong? And if brain implants are performed not for treatment but to improve people’s abilities, will that make the world an even more unequal place?

7 . The World Needs Zoos
ZOOS play an important role in the world for conservation and education. They are particularly important for endangered species. Many animals are critically endangered and may go extinct in the wild, but in zoos, they are going strong. Many others are already extinct in the wild and only survive thanks to populations kept in captivity (圈养). Even those critical of zoos often recognize that it is better to have species preserved somewhere than lose them altogether.
Take the ring-tailed lemur (环尾狐猴) of Madagascar for example. This animal is almost ubiquitous in zoos as they breed well in captivity and the public are fond of them. However, despite their high numbers in collections around the world, they are the most threatened mammalian group on the planet. A recent survey suggests that up to 95 percent of the wild populations have been lost since 2000.
Such trends are not isolated. The giraffe is another very common species in zoos. Unlike the lemurs, giraffes are widespread in the countries across much of sub-Saharan Africa. Yet giraffe populations have gone down by a third in the last thirty years. While less dramatic than the drop in lemur numbers, this is obviously a major loss and again, whole populations (which some scientists think are of unique subspecies) are on the verge of extinction.
There will, I suspect, always be resistance to the argument for keeping animals in captivity and I will not defend the zoos that are bad and in desperate need of improvement or closure.
A.So we can see many endangered animals living in zoos. |
B.This is a trend that is only likely to continue. |
C.This means that the remaining individuals are at serious risk. |
D.In fact, species that are common can also come under serious threat before people realize it. |
E.But unfortunately that is not always the case. |
F.But if we wish to keep any real measure of biodiversity on the planet, we may have to lean on zoos far more than many realize. |
8 . Pollution
Pollution happens when the environment is dirtied, by waste, chemicals, and other harmful substances(物质).Pollution is a problem all over the world. But it is especially bad in large cities with a lot of industries and cars.
Wildfires, volcanoes, and industrial chemicals cause some air pollution. But most air pollution comes from burning fossil fuels (矿物燃料)These include coal, oil and natural gas. The burning of fossil fuels may release harmful gases. Air pollution may cause such diseases cancer and asthma. It also leads to polluted rain that can harm living things
Causes of water pollution are easy to see. People dump(倾倒) garbage and dirty water into river, lakes and oceans. Factories or cities sometimes release poisonous chemicals, and other wastes into water. These chemicals may make the groundwater unfit to drink.
Littering, or throwing garbage on the ground, is a form of land pollution. Litter can destroy the habitats of plants and animals. The buildup of dangerous chemicals in the ground is another form of land pollution. The chemicals may come from farms or factories.
Many governments, environmental groups, and ordinary people are working to control pollution. Governments have passed laws to keep people from releasing dangerous chemicals into the environment
A.Farmers use chemical to help crops grow. |
B.This type of pollution may be seen in big cities. |
C.They also can harm fish and other forms of life. |
D.These chemicals can spread to plants and animals. |
E.In addition, air pollution may be a cause of global warming. |
F.There are three main forms of pollution: air, water, and land. |
G.Some companies and people are trying to use fewer fossil fuels. |
9 . 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.

10 . It’s late in the evening, time to close the book and turn off the computer. You’re done for the day. What you may not realize, however, is that the learning process actually continues in your dreams.
It might sound like science fiction, but researchers are increasingly focusing on the relationship between the knowledge and skills our brains absorb during the day and the often strange imaginings they generate at night. Scientists have found that dreaming about a task we’ve learned improves performance in that activity (suggesting that there’s some truth to the popular idea that we’re “getting” a foreign language once we begin dreaming in it). What’s more, dreaming may be an essential part of understanding, organizing and retaining what we learn.
While we sleep, research indicates, the brain replays the patterns of activity it experienced during waking hours, allowing us to enter what one psychologist calls a neural (神经的) virtual reality. A vivid example of such replay can be seen in a video researchers made recently about sleep disorders. They taught a series of dance moves to patients suffering from sleepwalking and related conditions. They then videotaped the subjects as they slept. Lying in bed, eyes closed, one female patient on the tape performs the dance moves she learned earlier.
This shows that while our bodies are at rest, our brains are drawing what’s important from the information and events we’ve recently encountered, then integrating that material into the vast store of what we already know. In a 2010 study, researchers reported that college students who dreamed about a computer maze (迷宫) task they had learned showed a 10-fold improvement in their ability to find their way through the maze compared with participants who did not dream about the task.
That study’s chief researcher Herbert Smith suggested that studying right before bedtime or taking a nap following a study session in the afternoon might increase the probability of dreaming about the material. Think about that as you go to sleep tonight.
