1 . Travelling abroad can present many challenges, including long journeys, language problems, and culture shocks, plus the expense of transport and accommodation.
One of the wonderful benefits of going abroad is that you can learn history and culture without real effort. There’s a natural tendency to absorb other cultures and pick up historical concepts, while enjoying yourself at the same time.
Another great benefit is that living in a foreign culture is the only real way to fully understand its language.
Removing yourself from the familiar and travelling to a new country can be a very powerful tool for gaining self-awareness and deeper understanding.
A.It’s far superior to learning it in a classroom. |
B.The new land gives you a fresh social environment. |
C.The direct experience helps you remember something easily. |
D.Many people wonder what they should do in a foreign country. |
E.Travelling abroad can also boost creativity and drive innovation. |
F.Another benefit of travelling abroad is the relaxation you can get. |
G.However, there’s rarely a dull moment when you’ re in a different country. |
2 . Atomic shapes are so simple that they can’t be broken down any further. Mathematicians are trying to turn to artificial intelligence (AI) for help to build a periodic table of these shapes, hoping it will assist in finding yet-unknown atomic shapes.
Tom Coates at Imperial College London and his colleagues are working to classify atomic shapes known as Fano varieties, which are so simple that they can’t be broken down into smaller components. Just as chemists arranged element s in the periodic table by their atomic weight and group to reveal new insights, the researchers hope that organizing these atomic shapes by their various properties will help in understanding them.
The team has given each atomic shape a sequence of numbers based on its features such as the number of holes it has or the extent to which it bends around itself. This acts as a bar code (条形码) to identify it. Coates and his colleagues have now created an AI that can predict certain properties of these shapes from their bar code numbers alone, with an accuracy of 98 percent.
The team member Alexander Kasprzyk at the University of Nottingham, UK, says that the AI has let the team organize atomic shapes in a way that begins to follow the periodic table, so that when you read from left to right, or up and down, there seem to be general patterns in the geometry (几何) of the shapes.
Graham Nib lo at the University of Southampton, UK, stresses that humans will still need to understand the results provided by AI and create proofs of these ideas. “AI has definitely got unbelievable abilities. But in the same way that telescopes (望远镜) don’t put astronomers out of work, AI doesn’t put mathematicians out of work,” he says. “It just gives us new backing that allows us to explore parts of the mathematical landscape that are out of reach.”
The team hopes to improve the model to the point where missing spaces in its periodic table could point to the existence of unknown shapes.

3 . When you ask people to judge others by their speech, a trend emerges: Listeners dislike disfluency. Slow talkers producing loads of ums and pauses(停顿)are generally perceived as less charming. But science tells us there may be even more to disfluency.
Disfluencies do not occur in arbitrary positions in sentences. Ums typically occur right before more difficult or low-frequency words. Imagine you’re having dinner with a friend at a restaurant,and there’re three items on the table: a knife, a glass, and a wine decanter(醒酒器). Your friend turns to you and says, “Could you hand me the...um...” What would you assume they want? Since it’s unlikely that they will hesitate before such common words as knife, and glass, chances are you’ll pick up the decanter and ask, “You mean this?”
This is exactly what we demonstrated through controlled eye-tracking studies in our lab. Apparently, listeners hear the um and predict that an uncommon word is most likely to follow.Such predictions, though, reflect more than just simple association between disfluencies and difficult words; listeners are actively considering from the speaker’s point of view. For example, when hearing a non-native speaker say the same sentence but with a thick foreign accent, listeners don’t show a preference for looking at low-frequency objects. This is probably because listeners assume non-native speakers may have as much trouble coming up with the English word for a common object, like a knife, as for unusual ones and can’t guess their intention.
In another experiment, listeners were presented with an atypical speaker who produced disfluencies before simple words and never before difficult words. Initially, participants displayed the natural predictive strategy: looking at uncommon objects. However, as more time went by, and they gained experience with this atypical distribution of disfluencies, listeners started to demonstrate the contrary predictive behavior: They tended to look at simple objects when hearing the speaker say um.
These findings represent further evidence that the human brain is a prediction machine: We continuously try to predict what will happen next, even though not all disfluencies are created equal.

4 . ①A group of 41 states and the District of Columbia began a legal case against Meta, the parent company of Facebook, Instagram, WhatsApp and Messenger, insisting that the company knowingly used features on its platforms to cause children to overuse them. The accusations in the lawsuit raise a deeper question about behavior: Are young people becoming addicted to social media and the internet? Here’s what the research has found.
②David Greenfield, a psychologist and founder of the Center for Internet and Technology Addiction in West Hartford, Conn, said the devices tempt users with some powerful approaches. One is “intermittent reinforcement,” which creates the idea that a user could get a reward at any time. But when the reward comes is unpredictable. Adults are easily influenced, be noted, but young people are particularly at risk, because the brain regions that are involved in resisting temptation and reward are not nearly as developed in children and teenagers as in adults. Moreover, the adolescent brain is especially accustomed to social connections, and social media is all a perfect opportunity to connect with other people.
③For many years, the scientific community typically defined addiction in relation to substances, such as drugs, and not behaviors, such as gambling or internet use. That has gradually changed. In 2013, the Diagnostic and Statistical Manual of Mental Disorders, the official reference for mental health conditions, introduced the idea of internet gaming addiction.
④A subsequent study explored broadening the definition to “internet addiction.” The author suggested further exploring diagnostic criteria and the language, for instance, noting that terms like “problematic use” and even the word “internet” were open to broad interpretation, given the many forms the information and its delivery can take.
⑤Dr. Michael Rich, the director of the Digital Wellness Lab at Boston Children’s Hospital, said he discouraged the use of the word “addiction” because the internet, if used effectively and with limits, was not merely useful but also essential to everyday life.
⑥Greenfield agreed that there clearly are valuable uses for the internet and that the definition of how much is too much can vary. But he said there also were obvious cases where immoderate use disturbs school, sleep and other vital aspects of a healthy life. “Too many young consumers can’t put it down, ” he said.“ The internet, including social media like Meta, are the drugs affecting the mind.”

5 . 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.

6 . Animal appear to predict earthquakes by sensing electricity in the air — the first study to find reliable evidence of the phenomenon has shown.
Cameras revealed an “amazing” drop in the number of animals up to 23 days before a major quake hit their rainforest home at Yanachaga National Park in Peru. Lead scientist Dr Rachel Grant, from Anglia Ruskin University, said, “The results showed that just before the earthquake, animals’ activity dropped right down.”
On a normal day the cameras placed around Yanachaga National Park record between 5 and 15 animals. But in the 23 days before the earthquake, the number of animals dropped to five or fewer per day. No animals were photographed at all on five of the seven days immediately before the quake.
Another study showed that animal activity remained normal in the park over a different period when seismic (地震的) activity was low. Co-author, professor Friedemann Freund, said, “The cameras were located at an altitude of 900 meters. If air ionization occurred, the animals would escape to the valley below, where there were fewer positive ions ( 离子). With their ability to sense their environment, animals can help us understand small changes that occur before major earthquakes.”
Other evidence suggested that before the earthquake, the air around the high mountain sites filled with positive ions that can be produced when rocks are placed under stress. Positive ions have been known to cause ill effects in humans as well as animals. Scientists believe the animals were made to feel uncomfortable by the positive ions, leading them to avoid the area. They are thought to have escaped to lower ground, where the air was less ionized. The findings may help experts develop better short-term seismic forecasts.

7 . Philosophers have a bad reputation for expressing themselves in a dry and boring way. The ideals for most philosophical writing are precision, clarity, and the sort of conceptual analysis that leaves no hair un-split.
There is nothing wrong with clarity, precision, and the like — but this isn’t the only way to do philosophy. Outside academic journals, abstract philosophical ideas are often expressed through literature, cinema, and song. There’s nothing that grabs attention like a good story, and there are some great philosophical stories that delight and engage, rather than putting the reader to sleep.
One of the great things about this is that, unlike formal philosophy, which tries to be very clear, stories don’t wear their meanings on their sleeve — they require interpretation, and often express conflicting ideas for the reader to wrestle with.
Consider what philosophers call the metaphysics (形而上学) of race — an area of philosophy that explorers the question of whether or not race is real. There are three main positions that you can take on these questions. You might think that a person’s race is written in their genes (a position known as “biological realism”). Or you might think of race as socially real, like days of the week or currencies (“social constructionism”). Finally, you might think that races are unreal — that they’re more like leprechauns (一种魔法精灵) than they are like Thursdays or dollars (“anti-realism”).
A great example of a story with social constructionist taking on race is George Schuyler’s novel Black No More. In the book, a Black scientist named Crookman invents a procedure that makes Black people visually indistinguishable from Whites. Thousands of African Americans flock to Crookman’s Black No More clinics and pay him their hard-earned cash to undergo the procedure. White racists can no longer distinguish those people who are “really” White from those who merely appear to be White. In a final episode, Crookman discovers that new Whites are actually a whiter shade of pale than those who were born that way, which kicks off a trend of sunbathing to darken one’s skin-darkening it so as to look more While.
Philosophically rich stories like this bring more technical works to life. They are stories to think with.

8 . The next time San Francisco residents stop a taxi, they may step into a car with no one behind the wheel. Driverless taxis are now allowed to come on the city’s streets. On June 2, 2022, Cruise, a division of General Motors (GM), was approved to charge for rides in its self-driving cars, becoming the first company allowed to operate commercial driverless cars in a major US city.
Though Cruise is regarding it as a big win, its self-driving cars aren’t totally free to run on the streets of San Francisco as they please. Cruise vehicles will be limited to transporting passengers in less crowded areas of the city between 10 p.m. and 6 a.m. The speed limit is 30 mph. They are also not allowed to operate in heavy rain or fog. The rules are meant to reduce any injuries or accidents.
Cruise plans to launch the service gradually with a team of just 30 cars. The first robotaxis will be improved versions of GM’s Chevrolet Bolt. However, the company is seeking approval to get its custom-built Cruise Origin on public roads. The driverless electric vehicle has no wheels or pedals (踏板) and can attain highway speeds. The car consists mostly of a siting space, where passengers can face each other.
Cruise’s ability to obtain the commercial permit to operate is a big step forward. However, the company still has to convince passengers that its technology is safe. Many remain concerned about safety. A 2021 survey by the American Automobile Association found that 74 percent of Americans are afraid to ride in a self-driving vehicle.
It remains to be seen how the new driverless taxi experiment will play out in San Francisco. But based on the vast number of companies that are racing to develop self-driving vehicles and the tens of thousands of people on waitlists for robotaxi rides, the Cruise pioneering program is at least set for popularity, if not success.
1. What can we learn about the Cruise’s driverless ride services?A.The services have turned out to be a great success. |
B.The services receive great support from the public. |
C.The services have run in some major cities of the USA. |

9 . Preamble of《China: Democracy that works》
Published by the State Council on December 4, 2021
Democracy is a common value of humanity and an ideal that has always been cherished by the Communist Party of China and the Chinese people.
This year marks the centenary of the CPC. Since its founding in 1921, the Party has taken wellbeing for the Chinese people and the rejuvenation of the Chinese nation as its abiding goals, and has made continuous efforts to ensure the people’s status as masters of the country. China is a country with a feudal (封建的) history dating back several thousand years that descended into a semi-feudal and semi-colonial society after the Opium War of 1840. Over the past hundred years, the Party has led the people in realizing people’s democracy in China. The Chinese people now truly hold in their hands their own future and that of society and the country.
The people’s status as masters of the country is the essence of people’s democracy. Since the 18th CPC National Congress in 2012, with a deeper understanding of China’s path to democracy and the political system, the Party has developed whole-process people’s democracy as a key concept and striven to translate it and relevant democratic values into effective institutions and concrete actions.
Whole-process people’s democracy integrates process-oriented democracy with results-oriented democracy, procedural democracy with substantive (本质上的) democracy, direct democracy with indirect democracy, and people’s democracy with the will of the state. It is a model of socialist democracy that covers all aspects of the democratic process and all sectors of society. It is a true democracy that works.
Democracy is a concrete phenomenon that is constantly evolving. Rooted in history, culture and tradition, it takes diverse forms and develops along the paths chosen by different peoples based on their exploration and innovation.
The best way to evaluate whether a country’s political system is democratic and efficient is to observe whether the succession of its leaders is orderly and in line with the law, whether all the people can manage state and social affairs and economic and cultural undertakings in conformity with legal provisions, whether the public can express their requirements without hindrance, whether all sectors can efficiently participate in the country’s political affairs, whether national decision-making can be conducted in a rational and democratic way, whether people of high caliber in all fields can be part of the national leadership and administrative systems through fair competition, whether the governing party is in charge of state affairs in accordance with the Constitution and the law, and whether the exercise of power can be kept under effective restraint and supervision.
Democracy is not a decorative ornament, but an instrument for addressing the issues that concern the people. Whether a country is democratic depends on whether its people are truly the masters of the country; whether the people have the right to vote, and more importantly, the right to participate extensively; whether they have been given verbal promises in elections, and more importantly, how many of these promises are fulfilled after elections; whether there are set political procedures and rules in state systems and laws, and more importantly, whether these systems and laws are truly enforced; whether the rules and procedures for the exercise of power are democratic, and more importantly, whether the exercise of power is genuinely subject to public scrutiny and checks.
Democracy is the right of the people in every country, rather than the prerogative of a few nations. Whether a country is democratic should be judged by its people, not dictated by a handful of outsiders. Whether a country is democratic should be acknowledged by the international community, not arbitrarily decided by a few self-appointed judges. There is no fixed model of democracy; it manifests itself in many forms. Assessing the myriad political systems in the world against a single yardstick and examining diverse political structures in monochrome are in themselves undemocratic.
In the richly diverse world, democracy comes in many forms. China’s democracy is thriving alongside those of other countries in the garden of civilizations. China stands ready to contribute its experience and strength to global political progress through cooperation and mutual learning.
