1 . Who is a genius? This question has greatly interested humankind for centuries.
Let’s state clearly: Einstein was a genius. His face is almost the international symbol for genius. But we want to go beyond one man and explore the nature of genius itself. Why is it that some people are so much more intelligent or creative than the rest of us? And who are they?
In the sciences and arts, those praised as geniuses were most often white men, of European origin. Perhaps this is not a surprise. It’s said that history is written by the victors, and those victors set the standards for admission to the genius club. When contributions were made by geniuses outside the club—women, or people of a different color or belief—they were unacknowledged and rejected by others.
A study recently published by Science found that as young as age six, girls are less likely than boys to say that members of their gender(性别)are “really, really smart.” Even worse, the study found that girls act on that belief: Around age six they start to avoid activities said to be for children who are “really, really smart.” Can our planet afford to have any great thinkers become discouraged and give up? It doesn’t take a genius to know the answer: absolutely not.
Here’s the good news. In a wired world with constant global communication, we’re all positioned to see flashes of genius wherever they appear. And the more we look, the more we will see that social factors(因素)like gender, race, and class do not determine the appearance of genius. As a writer says, future geniuses come from those with “intelligence, creativity, perseverance(毅力), and simple good fortune, who are able to change the world.”

2 . Some people prefer to have a bite to eat before hitting the gym, known as a fed workout. Others would like to wait until after exercising to refuel their bodies, called a fasted workout.
If you want energy and strength for an ideal workout, you need fuel. A fed workout will provide your body with power. Eating before exercise may help you sustain longer sessions and lift heavier weights.
Many fitness enthusiasts are not on board with this idea. They report feeling sick and inactive while trying to exercise after eating. With a fasted workout, you may not get the usual indigestion. Experts for fasted workouts further claim that eating afterwards makes your body use its fat reserves for energy, meaning you will burn more fat.
Deciding when to eat for an ideal workout is a personal choice. Both fasted workouts and fed activities have their benefits and shortcomings.
| A．However, a fasted workout might not work for you. |
| B．How your body will respond is based on your workout intensity. |
| C．These benefits can result in burning more fat and shaping a slimmer body. |
| D．To eat or not to eat, that is the question on many fitness enthusiasts’ minds. |
| E．Think thoroughly and discuss with your fitness instructor before taking a choice. |
| F．Knowing what to eat for an ideal workout is just as important as knowing when to eat. |
| G．A person doing a 30-minute session a day may not have a problem with fasted workouts. |
3 . The artificial-intelligence chatbot ChatGPT has shaken educators since its November release. New York City public schools have banned it from their networks and school devices. There is, perhaps surprisingly, one subject area that doesn’t seem threatened, It turns out ChatGPT is quite bad at maths.
“I’m not hearing maths instructors express concern about ChatGPT,” said Paul von Hippel, a professor at the University of Texas who studies data science and statistics. “I’m not sure it’s useful for maths at all, which feels strange because maths was the first-use case for the artificial-intelligence devices.”
ChatGPT’s struggle with maths is inherent in this type of AI, known as a large language model. It scans a large amount of text from across the web and develops a model that might be extremely effective for writing grammatically correct responses to essay requirement, but not for solving a maths problem.
In an email, I asked Debarghya Das, a search-engine engineer, why ChatGPT gets some simple questions right but others completely wrong. “Maybe the right analogy (类比) is if you ask a room of people, who have no idea what maths is but have read many hieroglyphics (象形文字), ‘What comes after 2+2,’ they might say, ‘Usually, we see a 4,’ That’s what ChatGPT is doing.” But, he adds, “Maths isn’t just a series of hieroglyphics. It’s the process of calculating.”
It isn’t great for pretending you know it through a maths class because you only recognize the mistakes if you know the maths. Another reason that maths instructors are less anxious about this innovation is that they have been here before. The field was upended for the first time decades ago with the general availability of computers and calculators.
“Maths has had the biggest revolution based on machinery of any mainstream subject,” said Conrad Wolfram, the strategic director of Wolfram Research. “In the real world, since computers came along, have maths, science and engineering gotten conceptually simpler? No, completely the opposite. We’re asking harder and harder questions, going up a level.”
Eventually, AI will probably get to the point where its maths answers are not only confident but correct. A pure large language model might not be up for the job, but the technology will improve. In general, however, AI, like computers, will likely ultimately be most useful for those who already know a field well. They know the questions to ask, how to identify the shortcomings and what to do with the answer. A tool, in other words, is for those who know the most maths, not the least.
1. What does the underlined word “inherent” in Paragraph 3 most probably mean?| A．Stable. | B．Practical. | C．Limited. | D．Natural. |
| A．Calculating requires some knowledge of hieroglyphics. |
| B．ChatGPT is good at solving mathematical questions by analogy. |
| C．Reading hieroglyphics prevents ChatGPT solving maths questions. |
| D．ChatGPT’s response is based on language models instead of calculations. |
| A．ChatGPT is useful to identify maths mistakes. |
| B．Technical revolution made maths easier to understand. |
| C．New technology will end up pushing the boundaries of maths. |
| D．ChatGPT has been banned from networks and school devices. |
| A．It will play the largest role for professionals in a field. |
| B．It will become confident to solve all the maths problems. |
| C．It will turn the maths field over again just like computers. |
| D．It will take the jobs from humans as the technology improves. |
4 . Why Boundaries at Work Are Essential
What is a boundary, you ask? A boundary is a limit defining you in relation to someone or something.
Letting co-workers know you are not comfortable shaking their hands or hugging them at a holiday party, especially with Covid at this time, is another example of setting a physical boundary. It is often easier to understand a physical boundary. Emotional or mental boundaries may be subtler (更微妙的).
Emotional boundaries are related to our feelings and how something or someone’s behavior affects us. For example, if a boss treats you disrespectfully by yelling at you or a colleague frequently interrupts you in meetings, you are likely to feel hurt, embarrassed, and perhaps angry. Understandably, by having a courageous conversation with both your boss and co-worker about their behavior, the impact it has on you, and your expectations regarding future behavior, you are setting healthy emotional boundaries for yourself at work.
Sometimes we set a boundary that is a combination of both a physical and emotional one.
Mental boundaries are related to our beliefs, values, cultural norms, ethics (道德), and standards. For example, you value a workplace culture that treats employees and clients with respect and dignity and acts ethically. After six months, you realize that company leaders are repeatedly behaving in ways not consistent with this.
| A．Why are boundaries important? |
| B．However, they are equally, if not more, important. |
| C．Therefore, we need to tell the difference between them. |
| D．Setting a boundary in the above example may be quite helpful. |
| E．Boundaries can be physical, mental, emotional, tangible, or intangible. |
| F．Your values and ethical standards don’t match with your company’s, which likely will lead to internal conflict. |
| G．Such boundaries often involve being asked to do more than we feel capable of for an extended period of time. |
What may well be the oldest metal coins in the world have been identified at an ancient abandoned city known as Guanzhuang in China. Like many Bronze Age (青铜时代) coins from the region, they were cast in the shape of spades with finely carved handles. These ancient coins existed during an in-between period between barter (以物易物) and money, when coins were a novel concept, but everybody knew that agricultural tools were valuable.
Reading about this incredible discovery, I kept thinking about the way modern people represent computer networks by describing machines as having “addresses”, like a house. We also talk about one computer using a “port” to send information to another computer, as if the data were a floating boat with destination. It’s as if we are in the Bronze Age of information technology, grasping desperately for real-world reference to transform our civilization.
Now consider what happened to spade coins. Over centuries, metalworkers made these coins into more abstract shapes. Some became almost human figures. Others’ handles were reduced to small half-circles. As spade coins grew more abstract, people carved them with number values and the locations where they were made. They became more like modern coins, flat and covered in writing. Looking at one of these later pieces, you would have no idea that they were once intended to look like a spade.
This makes me wonder if we will develop an entirely new set of symbols that allow us to interact with our digital information more smoothly.
Taking spade coins as our guide, we can guess that far-future computer networks will no longer contain any recognizable references to houses. But they still might bring some of the ideas we associate with home to our mind. In fact, computer networks — if they still exist at all — are likely to be almost the indispensable part of our houses and cities, their sensors inset with walls and roads. Our network addresses might actually be the same as our street addresses. If climate change leads to floods, our mobile devices might look more like boats than phones, assisting us to land.
My point is that the metaphors of the information age aren’t random. Mobile devices do offer us comfort after a long day at work. In some sense, our desire to settle on the shores of data lakes could change the way we understand home, as well as how we build computers. So as we cast our minds forward, we have to think about what new abstractions will go along with our information technology. Perhaps the one thing we count on is that humans will still appreciate the comforts of home.

7 . Do you feel like you can remember things better when you actively engage with the information and create your own version of it?
Tests on the generation effect show that when users encounter a list of words presented in the form of fragments (片段), they will engage several areas of the brain to create words to fill in the blanks.
Teachers and instructors need to be aware of the role the generation effect can play in the classroom. Students who just receive written material they can read may not understand it as fully as students who engage with it by taking notes, completing writing exercises, and so forth.
In a word, it all boils down to active learning versus passive learning. Spending a few minutes actively producing content may just be the thing you were missing in your learning routine.
| A．That’s called the Generation Effect. |
| B．For students, the generation effect can also be important. |
| C．When they are asked to repeat the list later, their recall will be better. |
| D．A common example of the generation effect can be seen in spelling lessons for young students. |
| E．The simple act of writing can trigger(激发) the generation effect and help the students perform better on examinations. |
| F．They will find that actively using new information may create relationships between tasks in examinations. |
| G．The process of generating content may initiate some particular encoding (编码) processes that do not happen when simply reading. |
8 . Should schools report a student’s health to parents?
As if grades weren’t enough to worry about, some students now have weight on their minds too. The number of overweight children in the United States has more than doubled in the past 20 years, according to the U.S. Centers for Disease Control and Prevention.
As a result, schools in several states, from California to Pennsylvania, have started sending home "BMI report cards". Those schools send home a report of a student’s body mass index (BMI). BMI is a calculation of weight and height that tells whether a person is overweight for his or her age.
Some lawmakers say BMI reports warn parents of their children s health problem help fight against obesity. In 2003, former Arkansas Governor. Mike Huckabee helped launch the first program to report students’ BMI.
| A．Should schools send home BMI reports? |
| B．Obesity rates in that state have since stopped increasing. |
| C．Since then children with heart disease have received the reports. |
| D．Not everyone thinks that reporting students’ BMI is a good idea. |
| E．Schools agree that more activities are required for students to control weight. |
| F．Being obese, or severely overweight, can lead to health problems later in life. |
| G．Some people argue that schools that label students overweight are acting unfairly. |
9 . If you’ re reaching for the last piece of pizza at a party, and meanwhile see another hand going for it, your next move probably depends on how you feel and whom the hand belongs to. Your little sister — you might just grab the pizza. Your boss — you probably will give up. But if you’re hungry and feeling particularly confident, you might go for it.
Now researchers have made progress in understanding how mammals’ brain encodes social rank and uses this information to shape behaviours — such as whether to fight for that last pizza slice. They discovered that an area of the brain called the medial prefrontal cortex (mPFC) was responsible for representing social rank in mammals; changes to a mouse’s mPFC affect its dominance (支配) behaviour. But it was unknown how the mPFC represented this information and which neurons (神经元) were involved in changing dominance behaviour.
In the new study, Professor Kay Tye let groups of four mice share a cage, allowing a social hierarchy (等级) to naturally develop — some mice became more dominant and others more subordinate. As soon as the mice were paired up, he discovered, the activity of their mPFC neurons could predict — with 90 percent certainty — the rank of their opponent.
“We expected animals might only signal rank when they are in a competition,” says co-researcher Nancy. “But it turns out animals walk around with this representation of social rank all the time.”
When the researchers next asked whether the activity of the mPFC neurons was associated with behaviour, they found something surprising. The brain activity patterns were linked with slight changes in behaviour, such as how fast a mouse moved, and they also could predict — a full 30 seconds before the competition started — which mouse would win the food reward.
The winner was not always the more dominant, but the one engaged in a “winning mindset”. Just as you might sometimes be in a more competitive mood and be more likely to snatch that pizza slice before your boss, a subordinate mouse might be in a more “winning mindset” than a more dominant mouse and end up winning.
The areas of the mPFC associated with social rank and “winning mindset” are next to one another and highly connected. Signals on social rank impact the state of the brain involved in “winning mindset”. In other words, a subordinate mouse’s confidence and “winning mindset” may partially decrease when faced with a dominant one.
“This is further evidence to suggest that we are in different brain states when we are with others compared to when we’re alone,” says Tye. “Regardless of who you’re with, if you’re aware of other people around you, your brain is using different neurons.”
