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

I was invited to a cookout on an old friend’s farm in western Washington. I parked my car outside the farm and walked past a milking house which had apparently not been used in many years. A noise at a window caught my attention, so I entered it. It was a hummingbird (蜂鸟), desperately trying to escape. She was covered in spider-webs (蛛网) and was barely able to move her wings. She ceased her struggle the instant I picked her up.
With the bird in my cupped hand, I looked around to see how she had gotten in. The broken window glass was the likely answer. I stuffed a piece of cloth into the hole and took her outside, closing the door securely behind me.
When I opened my hand, the bird did not fly away; she sat looking at me with her bright eyes. I removed the sticky spider-webs that covered her head and wings. Still, she made no attempt to fly. Perhaps she had been struggling against the window too long and was too tired? Or too thirsty?
As I carried her up the blackberry-lined path toward my car where I kept a water bottle, she began to move. I stopped, and she soon took wing but did not immediately fly away.
Hovering (悬停), she approached within six inches of my face. For a very long moment, this tiny creature looked into my eyes, turning her head from side to side. Then she flew quickly out of sight.
During the cookout, I told my hosts about the hummingbird incident. They promised to fix the window. As I was departing, my friends walked me to my car. I was standing by the car when a hummingbird flew to the center of our group and began hovering. She turned from person to person until she came to me. She again looked directly into my eyes, then let out a squeaking call and was gone. For a moment, all were speechless. Then someone said, “She must have come to say goodbye.”

Self-esteem is the ruling view you have of yourself. This includes your beliefs about your inner qualities and how you think others see you.
People with healthy self-esteem don't need to boast about themselves to others. People with low self-esteem may tell you how much everyone loves them, what a great job they do at work, and how amazing they are at pretty everything under the sun even though they really wonder if it's true. People may see them as obnoxious or “full of themselves”.
If you're starting to think you may have low self-esteem, you can work on the way you talk to yourself. When you turn off negative self-talk, you can open the floor to positive reinforcements and access the courage to show different sides of yourself. It isn't going to feel good at first, though. Keep going until it becomes less and less and maybe even a few awkward laughs in the mirror may help.
However, in serious cases of low or even non-existent self-esteem, you may want to call in a professional or a specialist. Good mental health is important, and professionals doing psychotherapy do not pass judgement or give corrections.
| A．Self-esteem is not always rooted in reality, though. |
| B．You have the power to shape a new self-perception. |
| C．This encourages you to speak openly without worry. |
| D．The real test of character is whether they can learn from their mistakes. |
| E．Self-esteem refers to a person's overall sense of his or her value or worth. |
| F．People with a healthy level of self-esteem present themselves with a casual confidence. |
| G．With some practice and persistence, you will win this internal struggle to see your self-worth. |

5 . 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.

6 . Scientists have discovered more than 5,000 new species living on the seabed in an untouched area of the Pacific Ocean that has been identified as a future hotspot for deep-sea mining, according to a review of the environmental surveys carried out in the area.
It is the first time the previously unknown biodiversity of the Clarion-Clipperton Zone (CCZ), a mineral-rich area of the ocean floor that spans 1.7m sq miles between Hawaii and Mexico in the Pacific, has been comprehensively documented. The research will be critical to assessing the risk of extinction of the species, given contracts for deep-sea mining in the near-pristine area appear imminent.
Most of the animals identified by researchers exploring the zone are new to science, and almost all are unique to the region: only six, including a carnivorous sponge and a sea cucumber, have been seen elsewhere.
Contracts for mining exploration in the CCZ have been granted to 17 deep-sea mining contractors in an area covering 745,000 sq miles. The companies, which are backed by countries including Britain, the US and China, want to dig for minerals including cobalt manganese and nickel in part to sell to the alternative energy sector.
To better understand the impact of mining this fragile ecosystem and its newly discovered inhabitants, an international team of scientists has built the first “CCZ checklist” by compiling all the records from expeditions to the region. Published in the journal Current Biology, it includes 5,578 different species, of which an estimated 88% to 92% had never before been seen.
To study and collect specimens (样品) from the ocean floor, biologists have joined research cruises in the Pacific that send remote-controlled vehicles to traverse (穿越) the seabed 4,000 to 6,000 meters below. Adrian Glover, a deep-sea biologist at the NHM and senior author of the study described it as an “incredible privilege”. The expedition, funded through the Natural Environment Research Council and others, is backed by UK Seabed Resources (UKSR), a deep-sea mining company that operates the UK’s exploration area. The scientists watch operations by video link direct from the boat as new species are gathered by remote control vehicles in the darkness below.
The seabed, Glover said, is an “amazing place” where, despite the extreme cold and dark, life thrives. “One of the characteristics of the abyssal plain is the lack of food, but life has a way of persisting down there,” he said, “It’s a mystery.” One of the deep-sea animals discovered was nicknamed the “gummy squirrel”, because of its huge tail and jelly-like appearance, he said. There are also glass sponges, some of which look like vases.
With approval for deep-sea mining looming, Glover said he believed it was “imperative that we work with the companies looking to mine these resources to ensure any such activity is done in a way that limits its impact upon the natural world”.
1. What’s the meaning of the underlined word “imminent”?| A．Easy to carry out. | B．Ready to take place. |
| C．Hard to cope with. | D．Important to look over. |
| A．Identifying new species living on the seabed. | B．Assessing the risk of extinction of species. |
| C．Documenting the biodiversity of the area. | D．Exploring the potential for deep-sea mining. |
| A．Abundance of food. | B．Extreme lifeless environment. |
| C．Presence of glass sponges. | D．Prosperous life despite challenging conditions. |
| A．A magic zone:available to mining companies |

| C．An “amazing place”: new species booming |
| D．Deep-sea wonders: the new species found in a Pacific mining hotspot |
7 . 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. |

| D．To show the challenges faced by female physicians. |
| A．Solves. | B．Ignores. | C．Stresses. | D．Defends. |
| A．Gender equality has been achieved in medicine. |
| B．The problems faced by women are a thing of the past. |

| D．History books should cover the successes and struggles of women. |
8 . Wholesale prices for gas and electricity are increasing suddenly across Europe,raising the possibility of increases in already-high utility (公共事业）bills and further pain for people who have taken a financial hit fromCOVID-19.
Governments are struggling to find ways to limit costs to consumers as scant natural gas reserves present yet another potential problem, exposing the continent to even more price increases and possible shortages if it’s a cold winter.
In the U.K., many people will see their gas and electricity bills rise next month after the nation’s energy regulator approved a 12% price increase for those without contracts that lock in rates. Officials in Italy have warned that prices will increase by 40% for the quarter that will be billed in October.
There are multiple causes for the price increases, energy analysts say, including tight supplies of natural gas used to generate electricity, higher costs for permits to release carbon dioxide as part of Europe’s fight against climate change, and less supply from wind in some cases.
Analysts at S&P Global Platts say electricity prices have risen due to strong demand from places like data centers and electric cars, but above all because of the rise in the price of natural gas used in generating plants. Utility companies’ exposure to natural gas prices has increased as high-emission coal plants have been retired, while utilities face higher costs for carbon allowances required by the European Union’s emissions trading system, which is aimed at reducing emissions of greenhouse gases.
The tight gas market could bite even more sharply if there’s an unusually cold winter. That’s because European distributors did not refill reserves reduced during last winter as they typically had done in summer months. In March 2008, when the freeze named “the beast from the east” hit Europe, industrial users in the U.K got a notice that there was a risk of interruption, although it didn’t come to that.
Could Europe run out of gas? “The short answer is Yes, this is a real risk,” said James Huckstepp, an analyst at S&P Global Platts. “Storage stocks are at record lows and there isn’t currently any spare supply capacity that is exportable anywhere in the world.The longer answer is that it’s hard to predict how it will play out given that Europe has never run out of gas in two decades under the current distribution system.”
1. What does the underlined word “scant” in Paragraph 2 probably mean?| A．Total. | B．Additional. | C．Limited. | D．Regular. |
| A．The closure of some coal plants. |
| B．The great demand for electric cars. |
| C．The competition between utility companies. |
| D．The change in the emissions trading system. |
| A．More natural gas will be needed for industrial use. |
| B．European distributors don’t make good preparations. |
| C．It is not easy to fill reserves during the cold weather. |
| D．Utility companies work can be easily interrupted. |
| A．Europe is expected to seek help from other countries. |
| B．It is hard to control the gas price in Europe at present. |
| C．Europe might face a serious shortage of gas in the future. |
| D．There’s something wrong with Europe’s distribution system. |
9 . How to Feel Connected
It's easy to feel disconnected from what is going on around you in today's fast-paced world.
Consider why you feel disconnected. Knowing what is making you feel disconnected can help you choose the best ways to address it.
Interact with people in person. Technology is a great way to stay in touch, but sometimes you need to spend time with other people in person.
Your loved ones could feel shy, so you may never know how to improve your relationship unless you ask the right questions. Asking them to open the doors can give you some insight on what you can do. Learning this information can help to strengthen your bond.
Show your commitment to them. Simply showing up and being there for your loved ones says a lot about how much you value your relationships. Putting in the time shows them that you are committed and want to stay connected.
Show appreciation. A simple “thank you” goes a very long way. Unfortunately, it is something that people who are close often take for granted. Telling someone you appreciate their time, love, and efforts can strengthen your bond and help you to become more connected.
| A．Ask others what they need from you. |
| B．Sometimes you can feel isolated and distant from the ones you love. |
| C．Be brave to express your love. |
| D．Reach out to people to schedule a time to get together. |
| E．Attending family events, or simply visiting someone once a week can help to strengthen your relationship and keep it strong. |
| F．Targeting your efforts toward those issues allows you to close that distance more effectively. |
| G．You can have a gift delivered to friends on special occasions. |
10 . I have frequently taught Research Methods and Design to college students at several institutions. I love teaching this course. One reason, of course, is that I enjoy thinking about research methodology (方法学) and sharing it with others. The other reason, however, is the obvious impact that it has on students. Every term, one (if not more) student tells me how taking this course has affected him/her: “I used to just read articles and believe what they said, but now I find myself asking ‘Is this true? How do they know? Is this a well designed study?” That is what I want the students to achieve in this course.
This brings to mind something written by Dorothy L. Sayers in 1948. One of her books, The Lost Tools of Learning speaks to Sayers’ thoughts on education. “By teaching our young men and women to read, we have left them at the mercy of the printed words. By the invention of the film and the radio,we have made certain that no dislike for reading shall protect them from the constant battery of words, words, words. They do not know what the words mean: they are victims to words in their emotions instead of being the masters of them in their intelligence.”
We are well past the 1940s, but her observation is still relevant. Sayers’ point is well taken. In the world of 24-hour news and social media that often resembles (类似) the Wild West, the ability to carry out evaluations has never been more important. In order to resist the distortions with which we are constantly bombed in the media, as well as be able to present a persuasive argument, we must be able to reason well, and think and give a judgement carefully.
When my students begin the Research Methods and Design course, they are generally not content to read all those research article I give. However, by the end of the course, they are excited about their newly obtained abilities.
1. What is the author’s course goal for her students?| A．Thinking critically. | B．Reading deeply. |
| C．Designing studies well. | D．Questioning themselves. |
| A．It was boring. | B．It was worrying. |
| C．It was conventional. | D．It was useless. |
| A．Popular news. | B．Various evaluations. |
| C．Persuasive arguments. | D．Misleading information. |
| A．To review a book. | B．To introduce a writer. |
| C．To suggest a practical skill. | D．To criticize social media. |
