文章大意:本文是一篇议论文。文章讨论了艺术给人们带来的启示和影响。当人们第一次见到一件艺术作品时,我们的经历和感情或许会和它发生链接,从而影响或改变我们的想法,提高思想境界,但是这是如何发生的呢?文章就这个问题进行了讨论。

1 . Art Builds Understanding

Despite the long history of scholarship on experiences of art, researchers have yet to capture and understand the most meaningful aspects of such experiences, including the thoughts and insights we gain when we visit a museum, the sense of encounter after seeing a meaningful work of art, or the changed thinking after experiences with art. These powerful encounters can be inspiring, uplifting, and contribute to well-being and flourishing.

    1     It contributes to facilitating a better understanding of ourselves, the human condition, and moral and spiritual concepts. The question is how that happens — what are the attributes of meaningful experiences of art?

According to the mirror model of art developed by Pablo P. L. Tinio, aesthetic reception corresponds to artistic creation in a mirror-reversed fashion. Artists aim to express ideas and messages about the human condition or the world at large.     2     This results in the build-up of layers of materials — from initial studies and sketches to the final, refined piece. A viewer’s initial interaction with an artwork starts where the artist has left off. Their interaction first involves the processing surface features, such as color, texture, and the finishing touches applied by the artist during the final stages of the creative process.     3    

In addition, art making and art viewing are connected by creative thinking. Research in a lab at Yale University shows that an educational program that uses art appreciation activities builds creative thinking skills. It showed that the more time visitors spent engaging with art and the more they reflected on it, the greater the correspondence with the artists’ intentions and ideas.     4    

Correspondence in feeling and thinking suggests a transfer — between creator and viewer — of ideas, concepts, and emotions contained in the works of art. Art has the potential to communicate across space and time.     5     What it takes for this to happen is active engagement with art in contexts that facilitate this engagement, especially museums.

A.The viewers gain a new perspective on the story.
B.The theory of aesthetic cognitivism describes the value of art.
C.This helps to create connections and insights that otherwise would not happen.
D.To do so, they explore key ideas and continually expand them as they develop their work.
E.After spending more time with the work, the viewer begins to access the ideas of the artist.
F.For example, in one activity, people are asked to view a work of art from different perspectives.
G.Participants were more original in their thinking when compared to those who did not take part in the program.

文章大意:这是一篇说明文。主要介绍了在伦敦出租车和司机已经成为研究阿兹海默症的新焦点。他们的大脑中隐藏着一张伦敦街道地图,这让GPS技术相形见绌。原因是他们大脑中的海马体会随着工作年限的延长而继续扩大。

2 . Black taxis have been a common sight in London for many years. Now these taxis and their drivers have become the focus of a new study into Alzheimer’s (阿尔兹海默症). For those on the outside, it may seem that behind the wheel of these black taxis are just common people who help move us to our places. But hidden within their brains is a map of London’s streets that has put GPS technology to shame for many years.

“The knowledge”, the test for London’s taxi drivers, stands among the hardest tests one could ever experience. It includes remembering information repeatedly from the memory of minute details about between 25,000 and 56,000 streets in London, depending on who’s taking the test, from the Trafalgar Square to the tiniest residential lanes (居民巷).

Usually, the hippocampus (海马体) feels the influences of Alzheimer’s most. The hippocampus controls the brain’s short-term memory and spatial memory (空间记忆) systems. University College London and Alzheimer’s Research UK are coming together to study these taxi drivers’ brains. And the taxi drivers’ hippocampi continue to grow as they go on doing the job for more years. This suggests that perhaps there’s something we can do to reproduce the influence on the general population.

Lead researcher Hugo Spiers was part of the team which 20 years ago found that, like birds’, the taxi drivers’ hippocampi slowly got bigger. In fact, research has found for years that any animal that requires detailed spatial knowledge of their land experiences growth in the hippocampus.

Spiers’ team hopes to deal with Alzheimer’s by studying the taxi drivers’ brains, since the hippocampus becomes smaller with the development of Alzheimer’s. To collect more information, Spiers has asked thirty London’s taxi drivers connected to an MRI machine to drive around. The machine will allow the researchers to keep a real-time watch on the workings of the hippocampus. “It’s been a joy to help scientists fight the disease,” said taxi driver Robert Lordan.

1. What can we learn about “The knowledge”?
A.It lasts for a few minutes only.B.It invites some residents to be testers.
C.It is a great challenge to people’s memory.D.It is usually held in London’s busy streets.
2. What has been found about the taxi drivers’ hippocampi?
A.They are improved thanks to daily talks.B.They grow together with taxi drivers’ job.
C.They fail to control short-term memory.D.They are more likely to be influenced.
3. What does the research on animals show?
A.Animals’ hippocampi are quite different from humans’.
B.The new study can do good to animals as well.
C.More detailed studies on animals’ brains are needed.
D.Animals’ hippocampi are similar to humans’.
4. Why do researchers watch taxi drivers with an MRI machine?
A.To decide who has the largest hippocampus.
B.To find out what their hippocampi are doing at work.
C.To know how Alzheimer’s develops in their brains.
D.To test whether the machine influences the hippocampus.

文章大意:这是一篇说明文。主要介绍了一项新的技术进展,这一技术可以将大脑信号转化为语音和面部表情,从而能够改善那些因中风等疾病而失去说话能力的人的生活。

3 . Ann has been severely paralysed (瘫痪)for more than 18 years. She cannot speak and normally communicates. But now, she has been able to speak through an image on the computer using technology that translated her brain signals into speech and facial expressions.

The advance raises hopes that the technology could be on the edge of transforming the lives of people who have lost the ability to speak due to conditions like strokes (中风).

The latest technology uses tiny electrodes (电极) put on the top layer of the brain to detect electrical activity in the part of the brain that controls speech and face movements. These signals are translated directly into a digital avatar’s (化身) speech and facial expressions including smiling, frowning or surprise.

The team put 253 paper-thin electrodes on the top layer of Ann’s brain over an area important to speech. Afterwards Ann worked with the team to train the system to detect her unique brain signals for various speech sounds by repeating different phrases repeatedly. The computer learned 39 distinctive sounds and a Chat GPT-style language system was used to translate the signals into understandable sentences. This was then used to control an avatar with a voice personalised to sound like Ann’s voice before the injury, based on a recording of her speaking at her wedding.

The technology was not perfect, translating words incorrectly 28% of the time in a test run involving more than 500 phrases, and it generated brain-to-text at a rate of 78 words a minute, compared with the 110–150 words typically spoken in natural conversation. However, scientists said the latest advances in accuracy and speed suggest the technology is now at a point of being practically useful for patients. A crucial next step is to create a wireless form that could be put beneath the skull (颅骨).

1. How can Ann speak?
A.By tiny electrodes on her brain.
B.Through an avatar using the latest technology.
C.Through repeating different phrases repeatedly.
D.By a technology that detects her brain signals.
2. What is paragraph 3 mainly about?
A.How the technology works.
B.How the technology benefits the patients.
C.How the technology translates the brain signal.
D.How the technology is put into wide application.
3. Which is unnecessary to make the avatar sound like Ann?
A.Ann’s cooperation.B.Ann’s facial expressions.
C.An AI language system.D.A recording of Ann’s speaking.
4. What do we know about the technology according to the last paragraph?
A.It is a promising way to help patients.
B.Its translating speed is too slow.
C.It cannot be applied to patients.
D.It is not accurate in translating at all.

文章大意:这是一篇说明文。文章介绍了人们在做决定时,大脑中杏仁核的活动及其他部位的活动情况,因此在做决定之前可以做一些刺激身体或精神的事情,来帮助你的大脑产生最初的伽马波。

4 . Every decision we make is arrived at through hugely complex neurological processing. Although it feels as though you have a choice, the action that you ‘decide’ to take is entirely directed by automatic neural activity. Brain imaging studies show that a person’s action can be predicted by their brain activity up to 10 seconds before they themselves become aware they are going to act. Multiple neuroscientific studies show that even those important decisions that feel worked out are just as automatic as knee-jerk reactions (膝跳反应) (although more complex).

Decision-making starts with the amygdala: a set of two almond-shaped nuclei (杏仁状核) buried deep within the brain, which generate emotion. The amygdala registers the information streaming in through our senses and responds to it in less than a second, sending signals throughout the brain. These produce an urge to run, fight, freeze or grab, according to how the amygdala values various stimuli.

Before we act on the amygdala’s signals, however, the information is usually processed by other brain areas, including some that produce conscious thoughts and emotions. Areas concerned with recognition work out what’s going on, those concerned with memory compare it with previous experiences, and those concerned with reasoning, judging and planning get to work on constructing various action plans. The best plan—if we are lucky—is then selected and carried out. If any of this process goes wrong, we are likely to hesitate, or do something silly.

The various stages of decision-making are marked by different types of brain activity. Fast (gamma)waves, with frequencies of 25 to 100 Hz, produce a keen awareness of the multiple factors that need to be taken into account to arrive at a decision. If you are trying to choose a sandwich, for instance, gamma waves generated in various cells within the ‘taste’ area of the brain bring to mind and compare the taste of ham, hummus, wholemeal, sourdough, and so on. Although it may seem useful to be aware of the full range of choice, too much information makes decision-making more difficult, so irrelevant factors get dismissed quickly and unconsciously.

After this comparison stage, the brain switches to slow-wave activity (12 to 30 Hz). This extinguishes most of the gamma activity, leaving just a single ‘hotspot’ of gamma waves which marks the chosen option.

Although there is no ‘you’ outside your brain to direct what it’s doing, you can help it to make good decisions by placing yourself in a situation which is likely to make the process run more smoothly. Doing something that is physically or mentally stimulating before making a decision will help your brain produce the initial gamma waves that generate awareness of the competing options. Getting over-excited, on the other hand, will prevent the switch to the slow brainwaves, making it much harder to single out a choice.

1. Why does the writer mention “knee-jerk reactions” in the first paragraph?
A.To introduce the finding of the latest brain imaging studies.
B.To illustrate that decisions are not consciously thought out.
C.To call attention to a kind of neural reaction that is not very complex.
D.To show the difference between decision-making and other brain activity.
2. What does the amygdala do according to the passage?
A.It works out conscious thoughts and emotions.
B.It selects the best action plan for a given situation.
C.It dismisses factors that are irrelevant to the decision to be made.
D.It processes sensory information and generates emotional responses.
3. What can be concluded from paragraphs 4 and 5?
A.Slow-wave activity usually lasts longer than fast-wave activity.
B.The brain prioritizes information before settling on a final choice.
C.Decision-making is difficult when slow-wave activity occurs first.
D.The brain needs as much information as possible to make a decision.
4. How does engaging in stimulating activities help the decision-making process?
A.By preparing the brain to single out the most reasonable choice.
B.By helping the brain switch to slow-wave activity more quickly.
C.By getting the brain to focus on those most relevant alternatives.
D.By making the brain more aware of the factors and choices involved.

文章大意:本文是说明文。短文主要讲述了在信息驱动的社会中,塑造我们的世界观经常无法提供全面的现实视角。简单的想法可能很吸引人,但是我们会冒着过度简化复杂问题的风险,最终会影响我们的判断力,限制我们有效解决复杂问题的能力。我们应该与持有不同观点的人交谈并试图理解他们的观点,形成正确的观点。

5 . In our information-driven society, shaping our worldview through the media is similar to forming an opinion about someone solely based on a picture of their foot. While the media might not deliberately deceive us, it often fails to provide a comprehensive view of reality.

Consequently, the question arises: Where, then, shall we get our information from if not from the media? Who can we trust? How about experts- people who devote their working lives to understanding their chosen slice of the world? However, even experts can fall prey to the allure of oversimplification, leading to the “single perspective instinct” that hampers (阻碍) our ability to grasp the intricacies (错综复杂) of the world.

Simple ideas can be appealing because they offer a sense of understanding and certainty. And it is easy to take off down a slippery slope, from one attention-grabbing simple idea to a feeling that this idea beautifully explains, or is the beautiful solution for, lots of other things. The world becomes simple that way.

Yet, when we embrace a singular cause or solution for all problems, we risk oversimplifying complex issues. For instance, championing the concept of equality may lead us to view all problems through the lens of inequality and see resource distribution as the sole panacea. However, such rigidity prevents us from seeing the multidimensional nature of challenges and hinders true comprehension of reality. This “single perspective instinct” ultimately clouds our judgment and restricts our capacity to tackle complex issues effectively. Being always in favor of or always against any particular idea makes you blind to information that doesn’t fit your perspective. This is usually a bad approach if you would like to understand reality.

Instead, constantly test your favorite ideas for weaknesses. Be humble about the extent of your expertise. Be curious about new information that doesn’t fit, and information from other fields. And rather than talking only to people who agree with you, or collecting examples that fit your ideas, consult people who contradict you, disagree with you, and put forward different ideas as a great resource for understanding the world. If this means you don’t have time to form so may opinions, so what?

Wouldn’t you rather have few opinions that are right than many that are wrong?

1. What does the underlined word “allure” in Para.2 probably mean?
A.Temptation.B.Tradition.C.Convenience.D.Consequence.
2. Why are simple ideas appealing according to the passage?
A.They meet people’s demand for high efficiency.
B.They generate a sense of complete understanding.
C.They are raised and supported by multiple experts.
D.They reflect the opinions of like-minded individuals.
3. What will the author probably agree with?
A.Simplifying matters releases energy for human brains.
B.Constant tests on our ideas help make up for our weakness.
C.A well-founded opinion counts more than many shallow ones.
D.People who disagree with us often have comprehensive views.
4. Which of the following can be the best title of the passage?
A.Embracing Disagreement: Refusing Overcomplexity
B.Simplifying Information: Enhancing Comprehension
C.Understanding Differences: Establishing Relationships
D.Navigating Complexity: Challenging Oversimplification

文章大意:本文为一篇说明文。文章针对通常看法“需提升劳动人口技能以应对自动化浪潮”指出,现实中技能提升的机会往往向高学历者倾斜,应为真正面临危机的低学历者提供再培训机会。

6 . In the fog of uncertainty about how new technology will change the way we work, policymakers around the world have flocked to the same idea. No matter what the future brings, they say confidently, we will need to upskill the workforce in order to cope.

The view sounds reassuringly sensible. If computers are growing smarter, humans will need to learn to use them to humans’ advantage. Otherwise, they may run the risk of being replaced by computers.     1     .

Research published by the Social Mobility Commission shows that workers with degrees are over three times more likely to participate in training as adults than workers with no qualifications. That creates a virtuous circle for those who did well at school, and vicious circle for those who did not. If the robots are coming for both the accountants and the taxi drivers, you can bet the bean counters will be more able to retrain themselves out of danger.

    2     In the UK, the government introduced an “apprenticeship levy” a few years ago in an attempt to force employers to spend more on training. A surprising number have responded by sending their senior managers on “apprenticeships” at business schools.

It is no good criticizing employers for directing investments at their highly skilled workers. They are simply aiming for the highest return they can get. And, for some types of lower-paid work, it is not always true that technological progress requires more skills. The UK’s latest Employment and Skills Survey, which is performed every five years, suggests the use of literacy and numeracy skills at work has fallen since 2012, even as the use of computers has increased. The trouble is, when the computer makes your job easier one day, it might make it unnecessary the next. Many of those affected by automation will need to switch occupations, or even industries.     3    

It is time to revisit older ideas. The UK once had an energetic culture of night schools, for adults to attend after their day jobs. These institutions have been disappearing due to funding cuts. But a revival of night schools could be exactly what the 21st century needs.     4     They can also explore interests they never had a chance to nurture before.

It is still not clear whether the impact of new technology on the labour market will come in a trickle or aflood. But in an already unequal world, continuing to reserve all the lifeboats for the better-off would be a dangerous mistake.

A.Employers also invest more in better educated workers by launching employer-sponsored cmployee education programs.
B.According to an Oxford University study, nowadays employers are more likely to hire the first-year apprentices.
C.Rather than just “upskilling” in a narrow way, people could choose to learn an entirely new skill or trade.
D.But the truth is, the people who are being “upskilled” in today’s economy are the ones who need it the least.
E.People can effectively train or upskill themselves to meet their specific professional needs.
F.But a retailer or warehouse company is not going to retrain its staff to help them move to a different sector.

文章大意:本文是一篇说明文。当前,青少年的悲伤和抑郁情绪是一大心理问题。作者呼吁青少年的心理健康危机需要一种新的方法。

7 . Mental Health Crisis Among Teens Demands a New Approach

Since the CDC released its survey results last month showing alarmingly high rates of sadness and depressive thoughts among teens, fingers have been pointed from two sides at the causes of this crisis.     1    . Others say that today’s more secular(世俗的)culture has confused our most vulnerable young people. But neither side seems to grasp the true urgency of the issue.

According to the CDC’s findings, more than one in five of the 17,000 high school students surveyed reported mental breakdown. Their rates of sadness and hopelessness are the highest in a decade, reflecting an increasing trend exacerbated by society’s isolation(隔离)and stress.     2    .

Parents as well as teachers and others who have direct contact with children must accept this preventive approach. It is crucial that they not be afraid to ask direct questions about depressive thoughts.     3    . It is also especially important that parents understand what help is available to their children.

    4    . For example, we can demand equity equality, which means insurance coverage(保险范围)for behavioral illnesses health issues that is for physical , thus reducing the financial burden. We can also urge our congressmen to fund health programs and expand mental health professions.     5    . Put the politics aside. There are lives in the balance.

A.And they should resist the false idea that raising a question creates a risk that was not there before.
B.This means that we must put aside our disagreements and approach this issue as a matter of life and death.
C.Some have argued that the climate issue has created an existential threat and accompanying anxiety.
D.Hospitalization may also be appropriate when the person in question shows an immediate danger to themselves.
E.At the macro(宏观的)level, our country can do so much more to help people struggling with mental health problems and their families.
F.It’s time to stop blaming and turn our attention to this generation of struggling teenagers.
G.It’s time for those who have the power to amplify(放大)their voices and drive change to focus on helping teenagers and families access the help they need.

文章大意:本文为一篇说明文。文章引用《穿白大褂的女人》一书中的故事,三位女性在男性控制的领域占一席之地,她们努力获得成功过的故事鼓舞人心,但折射出当今行业存在的发展问题,女性在医疗行业职业发展与性别歧视的问题,折射出作者对未来医学行业女性发展良好的愿景。

8 . In the 19th century, three pioneering women struggled to find their place in a male-controlled field. Elizabeth Blackwell, Elizabeth Garrett Anderson and Sophia Jex-Blake—among the first female doctors—are the heroines of Olivia Campbell’s new book. The story is lively and interesting, and the main characters are full of personality and individualism. Jex-Blake is described as “big and confident, a determined educational reformer with large eyes and an even lager personality”. Garrett Anderson, referred to as “Lizzie” throughout, was equally determined but also educated, and polite. The result is a great read for anyone looking for an introduction to the history of medical women.

The biographies of the three women are woven into a bigger, grander story about medicine in the 19th century and it is slow and unwilling acceptance of female physicians (医师). Though British, Blackwell attended medical school in the US. “Lizzie” was admitted to the medical school only via a loophole (漏洞) in the admissions policy. And Jex-Blake’s attempt to sit a medical exam in Edinburgh was met with a storm of protest.

Unsurprisingly, the three heroines faced many difficulties, but their efforts finally proved successful. Women in White Coats is, therefore, a successful tale of social progress. The final concluding chapter paints a sunny picture of present-day equality within the medical profession. However, in its efforts to tell an inspiring story, the book glosses over continuing problems within the profession today. Though more women than men now graduate from medical school, they face struggles with career progression and sexism.

We need more books that don’t offer a “great white men” approach to history. However, they have to deal with the incomplete and uneven nature of progress. Inspiring as it is to read stories of heroines trying hard and succeeding against the odds, that isn’t the whole picture. Medicine might be better for women now than in the past, but the problems of the Victorian era continue to exist and we still have far to go.

1. Who might particularly enjoy reading Women in white Coats?
A.People favoring science fiction novels.
B.Researchers studying great white men in history.
C.Those interested in female pioneers in medicine.
D.Students curious about the development of medicine.
2. Why does the writer tell the stories of the three women in Paragraph 2?
A.To praise their strong personality.
B.To state the success of women in medicine.
C.To prove their determination and confidence.
D.To show the challenges faced by female physicians.
3. What do the underlined words “glosses over” mean in Paragraph 3?
A.Solves.B.Ignores.C.Stresses.D.Defends.
4. What can we infer from the last paragraph?
A.Gender equality has been achieved in medicine.
B.The problems faced by women are a thing of the past.
C.History books should inspire people with women’s success.
D.History books should cover the successes and struggles of women.

文章大意:本文为一篇议论文。《华尔街日报》报道中,Instagram对许多青少年用户的心理健康产生有害影响。但在作者看来,这是其诱发用户精神紧张,放大了自身的自尊问题所致,本质上是人的问题。

9 . Thanks to in-depth reporting by the Wall Street Journal, we now know that Facebook has long been aware its product Instagram has harmful effects on the mental health of many adolescent users. Young girls, in particular, struggle with their body image thanks to a constant stream of photos and videos showing beautiful bodies that users don’t think they can attain.

While the information the Journal covered is essential and instructive, it does not tell the whole story. Deep down, this is not an Instagram problem; it’s a people problem. Understanding that distinction can make the difference between a failed attempt to contain a teen’s interest in an addictive app and successfully addressing the underlying problem leading to mental distress induced (诱发) by Instagram.

Critics were quick to shame Facebook for sitting on the data and not releasing it to researchers or academics who asked for it. Others criticize the social media giant for not using the research to create a safer experience for its teen users. The anger, while understandable, is misplaced.

While I’m reluctant to defend Facebook, I’m not sure it’s reasonable to blame the company for withholding data that would hurt its business. Have you ever binge-watched (狂看) a Netflix series? I assure you it wasn’t a healthy endeavor. You were in active, likely did nothing productive, mindlessly snacked and didn’t go outside for fresh air. It is an objectively harmful use of time to stare at a TV or laptop for a full weekend. Should we respond by shaming Netflix for not alerting us to how damaging an addictive product can be?

While it’s reasonable to say Instagram makes esteem issues worse, it strains credulity (夸张到难以置信) to believe it causes them in the first place. You create your own experiences on social media. For the most part, you choose which accounts to follow and engage. If you’re already vulnerable to insecurities and self-sabotage (自损) — as many teens are — you will find accounts to obsess over. And this isn’t a new phenomenon.

Before social media, there were similar issues fueling self-esteem issues. Whether the target be magazines, movies or television shows depicting difficult-to-attain bodies, there has been a relatively steady chorus (异口同声) of experts nothing the damage new media could cause young viewers.

Self-esteem issues have an underlying cause — one that’s independent of social media use. Instagram merely enhances those feelings because it provides infinitely more access to triggers than older forms of media. It’s more worthwhile to address those underlying factors rather than to attack Facebook.

1. The author thinks the criticisms against Instagram __________.
A.are successful attempts to change teens’ interest in addictive apps
B.address the Instagram - induced mental pain
C.are only based on the data released by Facebook
D.are not directed at the fundamental problem
2. Netflix is mentioned to __________.
A.compare the criticisms against it and Facebook
B.defend why Facebook is to blame
C.suggest the critics’ remarks are not to point
D.show Netflix does more harm to teens
3. The Instagram problem is essentially a “people problem” in that __________.
A.it is human nature to get addicted to social media
B.users decide on their experiences on social media
C.people have a tendency to feel insecure online
D.people are keen on fabricating their self - profile
4. What is the passage mainly about?
A.the unprecedented criticism facing Facebook
B.the alarming online habits of teenagers worldwide
C.the root cause of Instagram - induced mental strains
D.the harmful impact of Instagram on teenagers

文章大意:这是一篇说明文。文章首先提出一个研究现状,即遗传学家对我们的DNA的哪些部分与我们的面部外观有关知之甚少,随后通过一系列的研究结果得出结论——预测长相仍然是一个挑战。

10 . It seems rather obvious that facial characteristics are determined by our genes. But until recently geneticists(遗传学家) had very little understanding of which parts of our DNA were linked to our facial appearance.

An international team of researchers identified more than 130 chromosomal(染色体的) regions associated with specific aspects of facial shape. This is a critical first step toward understanding how genetics impact our faces, Live Science noted.

Researchers scanned the DNA of more than 8,000 people and analyzed dozens of shape measurements from their 3D facial images to look at the statistical relationships between about 7 million genetic markers—known locations in the genetic code where humans vary—and the facial features.

“When we find a statistical relation between a facial feature and one or more genetic markers, it points us to a very precise region of DNA on a chromosome. The genes located around that region then become our prime candidates for facial features like nose or lip shape,” Seth Weinberg, co-author of the study, wrote on Live Science.

Researchers discovered some interesting patterns after looking at the implicated(牵涉其中) genes at these DNA regions. Your nose is the part that is most influenced by your genes. Areas like the cheeks, which are highly influenced by lifestyle factors like diet, showed the fewest genetic associations.

There is also a high degree of overlap(重合) between the genes involved in facial and limb development. This provides an important clue as to why many genetic syndromes(综合症) are characterized by both hand and facial malformations(畸形). Some genes involved in facial shape may be involved in cancer, too. It explains why people treated for pediatric(小儿科的) cancer show some distinctive facial features.

So, can someone take your DNA and construct an accurate image of your face? It’s unlikely. The 130-plus genetic regions that were identified explain less than 10 percent of the variation in facial shape. But even if we understood all of the genes impacting facial appearance, prediction would still be a big challenge. That’s because facial features are affected by other factors as well, such as age, diet, climate and sun exposure.

Still, the knowledge of patients’ genetic information can be an invaluable tool in creating personalized treatment plans in fields like orthodontics(畸齿矫正学) or reconstructive surgery. For example, if someday doctors can use genetics to predict when a child’s jaw will hit its growth peak, it will help them decide the best time to intervene.

1. What’s the main purpose of the research?
A.To explain why humans vary based on statistics.
B.To identify the factors impacting facial appearance.
C.To discover the link between genes and facial features.
D.To study the relationship between facial features and genetic markers.
2. What can we learn from the study?
A.The nose is most influenced by genes.
B.Facial malformations affect limb development.
C.The cheeks are most closely associated with age.
D.Facial shape and cancer are impacted by exactly the same genes.
3. How could the research benefit people?
A.It could improve orthodontic treatments.
B.It could be useful for changing facial shapes.
C.It could help recreate one’s jaw at an early age.
