文章大意:本文是一篇议论文。文章主要讨论了对话标签在小说创作中的应用。作者认为,尽管在创作时应该鼓励使用强有力的动词,但在对话标签中应避免使用过于创意的词汇,如“尖叫”、“低语”等,因为这些标签可能掩盖对话本身的光芒。对话应该是故事中的“钻石”,通过角色的语气、动作等自然表达情感,而不是通过对话标签。

2 . During a judging period for a recent short story contest, I started thinking a lot about dialogue tags. Because in many submissions characters didn’t “say” a thing. They shouted, they inquired, they assumed. Some characters screamed while others murmured. But no one “said” anything. And I started wondering why.

Why do we tell beginner writers to avoid creative dialogue tags in the first place? Why do we insist that characters should stick to “said,” “asked,” and the occasional “sighed?” And, if the advice is so of-repeated, why are writers still unable to resist the siren call of weep, scream, snap, or laugh?

The more I thought about it, the more I understood the temptation. We’re always encouraged to use strong, actionable verbs in our prose. Why walk when you can skip or wander? Why cry when you can sob or weep? Why wouldn’t we reach for exciting verbs instead of mild-boring dull-blah said? Why couldn’t each verb be a tiny sparkling gem in its own right?

The problem, I think, is that every jewel needs a setting to become something more than the sum of its parts. Without something to provide structure, a collection of the world’s most glorious diamonds would still only amount to a heap of rocks.

And a dialogue tag should never, ever be the diamond in any given sentence.

Dialogue is your diamond, friends. When we read your work, your dialogue should be so bright, so sparkling, so lifelike, so wonderfully realistic that our brains “hear” each line instead of merely reading it. We don’t need to be told a character is shouting — we can sense it in the way they spit out words, clench fists, or storm from the room.

A dialogue tag is a mere signpost along the narrative journey, gently indicating who said what. It’s part of a story’s experience, but it’s not part of the story itself, nor should it be treated as such. Dialogue tags are similar to lighting in a Broadway play: without it, the audience would have no idea what was going on, but it usually strives to shine without calling too much attention to itself.

What’s more, readers may not initially imagine a particular line being “sobbed.” When we reach the end of a sentence and find out our leading lady has actually sobbed instead of whispered, it pulls us right out of the story. We pause. We reread the line. We adjust our understanding and begin again. But that wonderful momentum when we’re fully immersed in the scene, holding our breath to find out what our heroine says next, is lost.

Creating a successful work of fiction is about giving the reader all the materials they need to build your fictional world in their mind and not a scrap more. Readers need believable dialogue. They need voices so compelling that they pop right off the page and into our ears. And if you’ve created dynamic characters who speak words we can really hear, you will never need to tell us how something was said.

Senior Editor

1. According to the Senior Editor, the beginner writers are tempted to ______.
A.replace a dull “said” with exciting verbs
B.omit what the character said in a dialogue
C.resist the warning against strong emotions
D.overuse the word “said” in their submissions
2. The Senior Editor compares dialogue tags to ______
A.glorious diamondsB.heaps of rocks
C.tiny, sparkling gemsD.Broadway play lighting
3. What can we learn from the passage?
A.Dialogue tags are said to be the most important aspect of storytelling.
B.Without dialogue tags, readers have to reread to adjust understanding.
C.Creative dialogue tags may interrupt readers’ wonderful reading flow.
D.Effective dialogue tags should describe characters’ emotions directly.
4. The writer most probably agrees that ______.
A.good works of fiction give as many materials as possible
B.readers cannot imagine a line without the dialogue tags
C.what was said should be prioritized over how it was said
D.writers should choose powerful words for dialogue tags

文章大意:这是一篇说明文。文章主要介绍了我们人类的心智理论,同时说明了黑猩猩虽和人类一样有政治才能,但是不一样的是,人类的政治知识不总是决定我们的行为。

3 . As Frans de Waal, a primatologist (灵长动物学家), recognizes, a better way to think about other creatures would be to ask ourselves how different species have developed different kinds of minds to solve different adaptive problems. Surely the important question is not whether animals can do the same things humans can, but how those animals solve the cognitive (认知的) problems they face, like how to imitate the sea floor. Children and some animals are so interesting not because they are smart like us, but because they are smart in ways we haven’t even considered.

Sometimes studying children’s ways of knowing can cast light on adult-human cognition. Children’s pretend play may help us understand our adult taste for fiction. De Waal’s research provides another interesting example. We human beings tend to think that our social relationships are rooted in our perceptions, beliefs, and desires, and our understanding of the perceptions, beliefs, and desires of others — what psychologists call our “theory of mind.” In the 80s and 90s, developmental psychologists showed that pre-schoolers and even infants understand minds apart from their own. But it was hard to show that other animals did the same. “Theory of mind” became a candidate for the special, uniquely human trick.

Yet de Waal’s studies show that chimps (黑猩猩) possess a remarkably developed political intelligence — they are much interested in figuring out social relationships. It turns out, as de Waal describes, that chimps do infer something about what other chimps see. But experimental studies also suggest that this happens only in a competitive political context. The evolutionary anthropologist (人类学家) Brain Hare and his colleagues gave a junior chimp a choice between pieces of food that a dominant chimp had seen hidden and other pieces it had not seen hidden. The junior chimp, who watched all the hiding, stayed away from the food the dominant chimp had seen, but took the food it hadn’t seen.

Anyone who has gone to an academic conference will recognize that we may be in the same situation. We may say that we sign up because we’re eager to find out what other human beings think, but we’re just as interested in who’s on top. Many of the political judgments we make there don’t have much to do with our theory of mind. We may show our respect to a famous professor even if we have no respect for his ideas.

Until recently, however, there wasn’t much research into how humans develop and employ this kind of political knowledge. It may be that we understand the social world in terms of dominance, like chimps, but we’re just not usually as politically motivated as they are. Instead of asking whether we have a better everyday theory of mind, we might wonder whether they have a better everyday theory of politics.

1. According to the first paragraph, which of the following shows that an animal is smart?
A.It can behave like a human kid.
B.It can imitate what human beings do.
C.It can find a solution to its own problem.
D.It can figure out those adaptive problems.
2. Which of the following statements best illustrates our “theory of mind”?
A.We talk with infants in a way that they can fully understand.
B.We make guesses at what others think while interacting with them.
C.We hide our emotions when we try establishing contact with a stranger.
D.We try to understand how kids’ pretend play affects our taste for fiction.
3. What can be inferred from the passage?
A.Neither human nor animals display their preference for dominance.
B.Animals living in a competitive political context are smarter.
C.Both humans and some animals have political intelligence.
D.Humans are more interested in who’s on top than animals.
4. By the underlined sentence in the last paragraph, the writer means that ________.
A.we know little about how chimps are politically motivated
B.our political knowledge doesn’t always determine how we behave
C.our theory of mind might enable us to understand our theory of politics
D.more research should be conducted to understand animals’ social world

文章大意:本文是一篇议论文。文章探讨了现代社会中工人、雇员以及社会阶层较高者的焦虑和不满情绪,呼吁转变社会制度,充分开发人类潜能,使生产和消费成为实现人的全面发展的手段。

4 . In general, the society is becoming one of giant enterprises directed by a bureaucratic (官僚主义的) management in which man becomes a small, well-oiled cog in the machinery. The oiling is done with higher wages, well-equipped factories and piped music, and by psychologists and “human-relations” experts; yet all this oiling does not change the fact that man has become powerless, that he does not wholeheartedly participate in his work and he is bored with it. In fact, the blue-collar and the white-collar workers have become economic puppets who dance to the tune of automated machines and bureaucratic management.

The worker and employee are anxious, seemingly because they might find themselves out of a job or they would say that they are unable to acquire any real satisfaction or interest in life. In fact, they feel desperate as they live and die without ever having confronted the fundamental realities of human existence as emotionally and intellectually independent and productive human beings.

Those higher up on the social ladder are no less anxious. Their lives are no less empty than those of their subordinates. They are even more insecure in some respects. They are in a highly competitive race. To be promoted or to fall behind is not a matter of salary but even more a matter of self-respect. When they apply for their first job, they are tested for intelligence as well as for the right mixture of submissiveness and independence. From the moment on they are tested again and again by the psychologists, for whom testing is a big business, and by their superiors, who judge their behavior, sociability, capacity to get along, etc. This constant need to prove that one is as good as or better than one’s fellow-competitor creates constant anxiety and stress, the very causes of unhappiness and illness.

Am I suggesting a return to the pre-industrial mode of production or to nineteenth-century “free enterprise” capitalism? Certainly not. Problems are never solved by returning to a stage which one has already outgrown. I suggest transforming the social system from a bureaucratically managed industrialism in which maximal production and consumption are ends in themselves into a humanist industrialism in which man and full development of his potentialities — those of all love and of reason — are the aims of social arrangements. Production and consumption should serve as means to this end, and should be prevented from ruling man.

1. By “a small, well-oiled cog in the machinery”, the author expresses the idea that man is _________.
A.an essential part of society with irreplaceable functions
B.expected to work in reasonable harmony with the rest of society
C.an unimportant component of society, though functioning smoothly
D.responsible for the smooth running of society and business operations
2. The real cause of the anxiety of the workers and employees is that _________.
A.they are filled with an overwhelming fear of being unemployed
B.they don’t have any genuine satisfaction or interest
C.they have to face the fundamental realities of human existence
D.they lack a sense of independence and productivity
3. Which of the following is closest in meaning to the underlined word “submissiveness”?
A.cautionB.obedienceC.commitmentD.optimism
4. What is the author’s purpose in writing the text?
A.To introduce the production mode of our ancestors.
B.To show the problematic situation in society.
C.To argue for full development of human potentials.
D.To help people escape production and consumption.

文章大意:本文是一篇记叙文。几十年前的一个夏日夜晚父亲抱起熟睡的作者,带作者去看流星,作者在多年后依然对这个夜晚记忆犹新。除此之外,作者还记得许多和父亲一起做的特殊事情,父亲通过一些小事激发作者的好奇心。作者意识到开阔孩子的视野并不需要花费很多时间,只需经常和孩子们一起做一些事情。

5 . 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.

1. What does the underlined sentence in paragraph 4 mean?
A.The child was still immersed in the beautiful scenery just now.
B.The child was too frightened to fall asleep because of darkness.
C.The child wanted to listen more to the music about falling stars.
D.The child felt grateful to his father for what he showed him.
2. All the things the author remember from his childhood are ________.
A.unusual and novelB.dangerous and demanding
C.strange and uncommonD.educational and thought-provoking
3. What can we learn from the last paragraph?
A.Parents should interfere more with their children’s learning.
B.Parents should push their children to try to do everything on their own.
C.Parents should devote energy to exploring new things for their children.
D.Parents should encourage children to be curious and explore new things in life.
4. What’s the best title for this passage?
A.Limitless knowledgeB.Father, the hero of my life
C.Curiosity aroused that nightD.The unusual things in my life

文章大意:本文是一篇议论文。文章讨论了新的人工智能工具ChatGPT的优点和局限性。

6 . A new artificial intelligence (AI) tool called ChatGPT has excited the Internet community with its superhuman abilities to solve math problems, produce college articles and write research papers. Some educators are warning that such Al systems will change the world of learning, teaching, and research, for better or worse.

Ethan Mollick, a professor at the University of Pennsylvania’s Wharton School of Business, sees its benefits as a learning partner. He has used it as his own teacher’s assistant, for help with preparing a lecture and grading instructions for MBA students. “You can ask it to find a mistake in your writing and correct it and tell you why you got it wrong,” he said. “It’s really amazing.”

But the superhuman assistant has its limitations (局限). ChatGPT was created by humans, after all. OpenAI has trained the tool using a large dataset of real human conversations. It sometimes lies to you, with confidence. There have been situations in which ChatGPT won’t tell you when it doesn’t have the answer.

That’s what Teresa Kubacka, a data scientist based in Zurich, Switzerland, found when she experimented with the language model. “I asked it about something that I thought that I know doesn’t exist (存在) so that I can judge whether it actually also has the idea of what exists and what doesn’t exist.” she said. ChatGPT produced an answer so specific sounding, backed with citations (引文), that Kubacka had to find out whether the made-up thing was actually real. “This is where it becomes kind of dangerous,” she said.

ChatGPT doesn’t produce good science, says Oren Etzioni, the founding CEO of the Allen Institute for AI. But he sees ChatGPT’s appearance as a good thing. He sees this as a moment for review. “ChatGPT is just a few days old, I like to say,” said Etzioni. “It’s giving us a chance to understand what he can and cannot do and to begin the conversation of ‘What are we going to do about it?’”

1. How did Ethan Mollick feel about ChatGPT?
A.It could be used in many different fields.
B.It was popular with university students.
C.It would replace teachers’ assistants.
D.It was advantageous to him.
2. What did Teresa Kubacka’s experiment with ChatGPT find?
A.The Al tool is not dependable sometimes.
B.The Al tool always gives wrong answers.
C.The Al tool does not always answer questions.
D.The Al tool gives dangerous guidance sometimes.
3. What does Oren Etzioni mean by saying those words in the last paragraph?
A.It is too early to discuss ChatGPT’s limitations.
B.ChatGPT is open for review and suggestions.
C.ChatGPT is worth praising for its superhuman abilities.
D.It takes time to see whether ChatGPT works well or not.
4. Which of the following shows the organization of the text?
A.B.
C.D.

文章大意:本文是一篇说明文,介绍了一项最新研究表明:睡前音乐会导致更多的睡眠中断,乐器音乐甚至比有歌词的音乐更糟糕。

7 . Do you listen to quiet music to help you wind down before sleep? However, this practice could be counter-productive, according to a new study by Michael K. Scullin and colleagues at Baylor University. The work, published in Psychological Medicine, found that bedtime music was associated with more sleep disruptions and that instrumental music is even worse than music with lyrics.

In the first study, 199 online participants living in the US reported on their sleep quality and music listening frequency and timing, as well as their beliefs about how this affected their sleep. Almost all—87%—believed that music improves sleep, or at least does not disrupt it. However, the team found that more overall time spent listening to music was associated with poorer sleep and daytime sleepiness. Just over three quarters of the participants also reported experiencing frequent “earworms”—having a song or tune “stuck” and replaying in their minds. A quarter reported experiencing these during the night at least once per week, and these people were six times as likely to report poor sleep quality. The team’s analysis suggested that listening specifically to instrumental music near bedtime was linked to more sleep-related earworms and poorer sleep quality.

The team then ran an experimental study on 48 young adults. After arriving at the sleep lab at 8:45 p. m., participants went to a quiet bedroom, where they completed questionnaires that included measures of stress, sleep quality and daytime sleepiness. They also had electrodes applied, ready for the night-time polysomnography to record their brain wave activity, as well as heart rate and breathing, and reported on how relaxed, nervous, energetic, sleepy and stressed they felt. At 10:00 p. m., they were given some “downtime”, with quiet music playing. Half were randomized to hear three songs while the other half heard instrumental-only versions of these same songs.

Participants reported decreases in stress and nervousness and increased relaxation after listening to either set of songs, and also showed decreases in blood pressure. So-as earlier studies have also suggested- quiet music at bedtime was indeed relaxing at the time. However, a quarter of the participants woke from sleep with an earworm, and the polysomnography data showed that instrumental versions of the songs were more likely to induce these awakenings as well as other sleep disruptions, such as shifts from deeper sleep to lighter sleep. Taken together, the findings represent “causal evidence for bedtime instrumental music affecting sleep quality via triggering earworms” the team writes.

Why instrumental-only songs should have a bigger impact than music with lyrics isn’t clear. The three songs used in this study were chosen because they were likely to be familiar. Hearing them without the lyrics might have prompted the participant’s brains to try to add the words, which might have made earworms more likely. If this is the case, all instrumental music may not have the same effect. However, the data from the first study is consistent with the idea that instrumental music generally is more of a problem.

1. According to the passage, the participants in both studies______.
A.were required to listen to light musicB.felt their sleeping problems resolved
C.had their sleeping quality monitoredD.provided feedback on bedtime music
2. What does the underlined word “induce” in Paragraph 4 probably mean?
A.Lead to.B.Impact on.C.Break in.D.Focus on.
3. What can we learn from the passage?
A.Earworms are mainly caused by music with lyrics.
B.Bedtime music leads to high blood pressure and anxiety.
C.Quiet music improves sleeping quality while loud music harms sleep.
D.Both familiar and unfamiliar instrumental music can cause sleeping problems.
4. The passage is mainly about______.
A.how instrumental music disturbs sleep
B.the possible negative effect of bedtime music
C.how people can improve their sleep quality
D.differences between music with and without lyrics

文章大意:本文是一篇新闻报道。文章通过介绍研究者们如何考虑城市中的感官体验来探讨城市规划中的一些新趋势和挑战。同时,文中也引用了多位专家的观点和案例来支持作者的立论。

8 . “When I stopped in at our local tourism office in Montreal to ask where they would recommend visitors to go to smell, taste, and listen to the city, I just received blank stares. They only know about things to see, not about the city’s other sensory attractions, its soundmarks and smellmarks,” says Howes, the director of Sensory Studies, a growing field often referred to as “sensory urbanism”.

Around the world, researchers like Howes are investigating how non-visual information defines the character of a city and affects its livability. Using methods ranging from low-tech sound walks to data collecting, wearables (clothing or glasses that contain computer technology), and virtual reality, they’re fighting what they see as a limiting visual preference in urban planning.

“Just being able to close your eyes for 10 minutes gives you a totally different feeling about a place,” says Oguz Öner, an academic and musician. He has spent years organizing sound walks in Istanbul where participants describe what they hear at different spots with their eyes covered. His research has identified locations where a wave organ could be constructed to strengthen the sounds of the sea, something he was surprised to realize people could hardly hear, even along the waterfront.

Although his findings have not been considered into local urban plans yet, this kind of individual feedback (反馈) about the sensory environment is already being put to use in Berlin, where quiet areas identified by citizens using a free mobile app have been included in the city’s latest noise action plan.

The best way to determine how people react to different sensory environments is a subject of some debate within the field. Howes and his colleagues are using observation and interviews to develop a set of best practices for good sensory design in public spaces. Other researchers are going more high-tech, using wearables to track biological data like heart-rate variability to reveal different sensory experiences.

As data collection about people’s sensory experiences becomes more widespread, many of these experts warn that concerns about privacy and surveillance (监视) need to be taken into account. Issues of fairness and inclusion also come into play when determining whose sensory experiences are factored into planning. “Sensory awareness is not independent or simply biological; whether we find something pleasant or not has been shaped culturally and socially,” says Monica Degen, an urban cultural sociologist at Brunel University London.

Degen cites the example of a London neighborhood where inexpensive restaurants for local youth were replaced by trendy cafes. “It used to smell like fried chicken,” she says, but newer residents found that smell annoying rather than welcoming. “Now it smells like the popular Italian coffee, cappuccinos.”

1. The underlined phrase “blank stares” in Paragraph 1 implies that______.
A.Montreal is lacking in visual appeal
B.Montreal’s non-visual information is ignored
C.the tourism officers object to sensory urbanism
D.there are too many tourist attractions to recommend
2. What can we learn from the passage?
A.Many methods are used to limit the visual preference.
B.Potential concerns about collecting data can be relieved.
C.People may fail to notice sound attractions even in better locations.
D.Individual feedback restricts the development of sensory environment.
3. What can be inferred from the passage?
A.People’s perceptions of their sensory surroundings are subjective.
B.Sensory urbanism needs to focus on developing sensory facilities.
C.Sensory experience is dominant in shaping the character of a city.
D.Choices of sensory attractions in urban planning depend on tourists.

文章大意:这是一篇说明文。文章介绍一项对昆虫趋光的研究,旨在帮助建筑行业避免那些最容易吸引昆虫的光线。

9 . “Flying insects don’t fly directly to lights from far away because they’re attracted to them, but appear to change course toward a light if they happen to be passing by due to a strange inborn biological response,” writes Samuel Fabian, a bioengineer, in a research paper.

Until now, the leading scientific hypothesis has been that insects use the moon’s light to direct the way at night and mistake artificial lights for the moon. But this idea doesn’t explain why insects that only fly during the day also gather around lights.

To find out what really happens, Samuel’s team track the precise movements of insects in the wild around lights using a high-speed camera. This revealed two notable behaviours. First, when insects fly above lights, they often invert (转向) themselves and try to fly upside down, causing them to fall very fast. Just after insects pass under a light, they start doing a ring road. As their climb angle becomes too steep, they suddenly stop and start to fall. Second, when insects approach a light from the side, they may circle or “orbit” the light.

The videos show that the inversions sometimes result in insects falling on lights. It can appear to the naked eye as though they are flying at the lights. “Instead, insects turn their dorsum toward the light, generating flight perpendicular(垂直) to the source,” the team write. It is common to the two behaviours that the insects are keeping their backs to the light, known as the dorsal light response (DLR). This DLR is a shortcut for insects to work out which way is up and keep their bodies upright, as the moon or sun is usually more or less directly above them, and this direction allows them to maintain proper flight attitude and control. They also find that the insects fly at right angles to a light source, leading to orbiting and unstable flights as the light’s location relative to them changes as they move.

Samuel’s team suggest that a possible outcome of the research could help the construction industry to avoid the types of light that most attract insects.

1. What does the research focus on?
A.Why insects gather around lights.
B.Where artificial lights lead insects to.
C.What biological response insects are born with.
D.How to design environment friendly artificial lights.
2. What can we learn about insects from the videos of their movements?
A.They fly directly to lights.B.They circle close to lights.
C.Their flying speed is steady.D.Their inversions can be controlled.
3. DLR makes insects ____________.
A.balance their flyingB.keep their route straight
C.decide their body positonD.shorten their flight distance

文章大意:本文是一篇议论文。作者在文中探讨了人工智能的最新发展所带来的焦虑和人类的应对办法。

10 . We humans are in trouble. We have let loose a new evolutionary process that we don’t understand and can’t control.

The latest leaps forward in artificial intelligence (AI) are rightly causing anxiety. Yet people are responding as though AI is just one more scary new technology, like electricity or cars once were. We invented it, the argument goes, so we should be able to manage it for our own benefit. Not so. I believe that this situation is new and potentially dangerous.

My thinking starts from the premise that all design anywhere in the universe is created by the evolutionary algorithm (算法). This is the process in which some kind of information is copied many times, the copies vary slightly and only some are selected to be copied again. The information is called the replicator (复制者), and our most familiar example is the gene.

But genes aren’t the only replicator, as Richard Dawkins stressed in The Selfish Gene. People copy habits, stories, words, technologies and songs; we change, recombine and pass them on in ever greater variety. This second replicator, evolving much faster than genes ever could, Dawkins called memes (模仿传递行为) — and they are selfish too.

As we face up to the recent explosion in AI, new questions arise. Could a third replicator take advantage of the first two? And what would happen if it did?

For billions of years, all of the Earth’s organisms were gene machines, until, about 2 million years ago, just one species — our ancestors — started imitating sounds, gestures and ways of processing food. They had let loose a second replicator and turned us into meme machines. Following the same principle, could a third replicator appear if some object we made started copying, varying and selecting a new kind of information?

It could, and I believe it has. Our digital technology can copy, store and spread vast amounts of information with near-perfect accuracy. While we had mostly been the ones selecting what to copy and share, that is changing now. Mindless algorithms choose which ads we see and which news stories they “think” we would like. Once a digital replicator takes off, its products will evolve for its own benefit, not ours.

All is not lost, though. We already cope with fast-evolving parasites such as viruses by using our immune systems, machines and vaccines. Now, we need to build our collective mental immunity, our critical thinking and our ability to protect our attention from all that selfish information. Taking lessons from evolution, we can stop imagining we are the controllers of our accidentally dangerous offspring and start learning how to live with them.
