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.

2 . 阅读下面材料，根据其内容和所给段落开头语续写两段，使之构成一篇完整的短文。

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.”

3 . 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.

1. What does the author think of philosophical stories?

A．The meaning behind is very obvious.

B．They am extremely precise and formal.

C．They often cause conflicts among readers.

D．They are engaging and inspire critical thinking.

2. Which category might “Christmas” fall into according to paragraph 4?

A．Social constructionism.	B．Anti-realism.
C．Biological realism.	D．Literary realism.

3. What is Black No More in paragraph 5 mainly about?

A．Racial issues caused by skin colors.

B．A society view on race and self-image.

C．Black people accepted by the white society.

D．The origin of sun bathing among white people.

4. What is the best title of the text?

A．Stories Made Easy	B．Stories to Think with
C．Positions in Philosophy	D．Nature of Philosophical Writing

4 . 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.     1     Someone can develop low self-esteem even when they are highly functional and greatly skilled. Understanding this mysterious emotional currency might be the key to unlocking your own self-worth.

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”.     2     They are not shy about sharing ideas, including constructive criticisms of others. They also take care of themselves without second-guessing or apologizing. They are the people who we say seem “sure 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.     3    

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.     4     It is the best way to get at the roots of your real self-esteem problems.

    5     It will take some work but your entire life — from your relationships to your body image to your work habits — will be touched with the kind of power that only comes from someone believing in themselves. This is the hardest part, and the greatest leap. With some changes and support, you can improve your self-esteem and see how everything else changes as a result.

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.

Stop Asian Hate

During the course of the COVID-19 pandemic, New York City saw a sharp increase in harassment and violence against Asian people and communities, especially Asian elders. Discrimination on the basis of race, national origin, age, and disability, including having or     1     (perceive) to be exposed to COVID-19, is illegal under the Human Rights Law.    2    the start of the pandemic, there has been a significant, troubling increase in anti-Asian hate crimes and bias incidents. These have been verbal attacks, physical and even things like the tragic shooting of eight Asian-American spa technicians in Atlanta, Georgia. Beginning in February of 2020, we received a sevenfold increase in reports of anti-Asian harassment, discrimination, and violence. It is crucial to note that hate crimes and bias incidents have been found to be vastly under-reported     3    these numbers reflect just a fraction.

We all want to live in a world that is free from prejudice and    4    everyone has the right to be proud of who they are. Unfortunately, this is a pretty tough ask. We’ve joined forces with other establishments to bring you some resources of the movement of Stop Asian Hate,     5    the aim is to an end to the rising tide of racism against east and south east asian (ESEA) people.

Since the pandemic, something has been made nasty in the media by comments from Donald Trump calling it “the China virus”, and ESEA people all over the world have found that their lives have been turned upside down. In the wake of the tragic deaths in the US and several studies     6    (reveal) the real increase of racism against this minority, the Stop Asian Hate movement started a conversation about what is going on. You can find out all about it on this website, and get resources and support to help you if you are dealing with the impacts     7    racism.

Working towards a world where no racism exists is always important to us, and will always be something     8    need to strive towards. The thing is, a lot of conversations around racism fail to distinguish between the multiple groups of people who are affected, and the issues     9     (face) by ESEA people will be completely different to other people of colour.

    10    the growth of attacks and hate crimes still on the rise, we want to give you the tools to be able to understand the value and necessity of our voice, and how to stand up and fight back.

6 . Now that we have briefly explored the history of the short story and heard from a few of its creators, let us consider the role of the reader. Readers are not empty vessels that wait, _______ raised, to receive a teacher’s or a critic’s interpretation. They bring their unique life experiences to the story. With these_______ , the best readers also bring their attention, their reading skills, and most importantly, their_______ to a reading of a story.

My students always_______ me to discuss, analyze, interpret, and evaluate the stories we read without destroying the excitement of being beamed up into another world. For years I _______with one response after the other to this challenge. Then one day I read an article by a botanist who had explored the beauty of flowers by x-raying them. His illustrations showed the rose and the lily in their_______ beauty, and his x-rays_______the wonders of their construction. I brought the article to class, where we discussed the benefits of examining the internal structure of flowers, relationships, current events, and short stories.

A short story, _______ , is not a fossil to admire. Readers must ask questions, guess at the answers,_______what will happen next, then read to discover. They and the author form a partnership that brings the story to life. Awareness of this partnership keeps the original excitement alive through discussion, analysis, interpretation, and ________. Literary explorations allow the reader to admire the authors’________ as well as their artistry. In fact, original appreciation may be enhanced by this x-ray vision. The final step is to appreciate once again the story________— to put the pieces back together.

7 . Hundreds of scientists, writers and academics sounded a warning to humanity in an open letter published last December: Policymakers and the rest of us must engage openly with the risk of global collapse. Researchers in many areas have projected the widespread collapse as “a credible scenario(情景) this century”.

A survey of scientists found that extreme weather events, food insecurity, and freshwater shortages might create global collapse. Of course, if you are a non-human species, collapse is well underway.

The call for public engagement with the unthinkable is especially germane in this moment of still-uncontrolled pandemic and economic crises in the world's most technologically advanced nations. Not very long ago, it was also unthinkable that a virus would shut down nations and that safety nets would be proven so disastrously lacking in flexibility.

The international scholars’ warning letter doesn't say exactly what collapse will look like or when it might happen. Collapseology, the study of collapse, is more concerned with identifying trends and with them the dangers of everyday civilization. Among the signatories(签署者) of the warning was Bob Johnson, the originator of the “ecological footprint” concept, which measures the total amount of environmental input needed to maintain a given lifestyle. With the current footprint of humanity, “it seems that global collapse is certain to happen in some form, possibly within a decade, certainly within this century,” Johnson said in an email.

“Only if we discuss the consequences of our biophysical limits,” the December warning letter says, “can we have the hope to reduce their speed, severity and harm”. And yet messengers of the coming disturbance are likely to be ignored. We all want to hope things will turn out fine. As a poet wrote,

Man is a victim of dope(麻醉品)

In the incurable form of hope.

The hundreds of scholars who signed the letter are intent(执着) on quieting hope that ignores preparedness. “Let's look directly into the issue of collapse,” they say, “and deal with the terrible possibilities of what we see there to make the best of a troubling future.”

1. What does the underlined word “germane” in Paragraph 3 probably mean?

A．Scientific.	B．Credible.
C．Original.	D．Relevant.

2. As for the public awareness of global collapse, the author is________.

A．worried	B．puzzled
C．surprised	D．scared

3. What can we learn from this passage?

A．The signatories may change the biophysical limits.

B．The author agrees with the message of the poem.

C．The issue of collapse is being prioritized.

D．The global collapse is well underway.

8 . 阅读下面短文，根据所给情节进行续写，使之构成一个完整的故事。

I needed to do something in my community (社区) in order to complete the community service hours required to graduate from high school. Some of my friends had signed up to spend time at a soup kitchen, so I did, too. It seemed like a good thing to do.

I thought that we would just be passing out dinners to those in need, but I found out we would be doing everything from preparing to serving the dinner. We began preparing the food, from mixing salad dressing to separating frozen meat. Much still needed to be done before dinner was served, but already outside the building many homeless people were gathering. It wasn’t until a couple of hours later that we opened the doors and began serving dinner.

As the line of people came toward me, I got a little scared. I’d come face to face with the homeless: How should I act? How would they treat me? Would they hate me for having more than they did? While some of the people looked very friendly, some of them looked so dangerous. I didn’t have too much time to worry about it. I was assigned (分配) to serve the salad with the lady next to me. She smiled at me and said if I needed help, she’d be right there, which I found quite comforting.

I had never seen so many people wanting food. They were of all ages and nationalities. Most of them wore clothes that were torn and dirty. Some looked like they had tally given up on life, while others seemed to be making the best of the situation, smiling and joking. Some were better off than others, but they all needed a good meal and a warm place to eat. It saddened me to think of how many people there were who didn’t have a place to call home and the only food they got came from a soup kitchen.

9 . My students frequently ask me how I planned out my career to become president of Fidelity Investments. I always tell them, “There was no grand plan; I backed into my career one step at a time.” In this tough economy and ever-changing world, it is more important than ever to smartly evaluate each step in your career. To prepare for whatever surprises lie ahead, try to make choices today that will maximize your options in the future.     1    

Gaining transferable (可转移的) knowledge begins with the choices you make at school. You want your education to provide you with the necessary skills and expertise to succeed in a wide variety of jobs.     2     I favor those that involve extensive writing, rigorous analysis, or quantitative skills.

Once you have finished your formal education, search for jobs that will allow you to further expand your transferable knowledge—to help you find your next job. Let’s say you take a job putting together airplane leases. Within a few years, you could become the world’s expert on the subject.     3     By contrast, if you take a job that will expand your computer programming skills, you can greatly boost your options for later steps in your career.

Remember gaining transferable knowledge is only one piece of the puzzle.     4     As a saying goes, “Organizations don’t hire people. People hire people.” The more people you know, the more people will think of you when a job pops open—even when it is not publicly advertised.

Of course, you can build your network to some degree without changing jobs.     5     But this sort of event-driven networking pales in comparison with the deep bonds you can develop with your colleagues by working, communicating, and traveling with them.

A．You can make yourself more attractive.

B．Gain transferable expertise and form close bonds with your colleagues.

C．Your next step should help you expand your web of personal relationships.

D．This later helped me evaluate and start business units throughout the world.

E．You can attend conferences or participate in committees at trade associations.

F．This means that you need to make smart choices about the courses you will follow.

G．However, this narrow expertise probably won’t help you in any other line of work.

A road trip

Out of all possible road trips, the best one is by car. You finish packing, put everything inside the car, sit inside it, buckle up, look at your friend     1     (sit) next to you, smile and ... go! And then begins the most wonderful part of the road trip. It is not the place you are heading to but what you see from the opened window of the car     2     matters. The best part is when you leave your home before the dawn. Personally,     3     I look in the direction of the east, I am always amazed by how the sun informs the world about its arrival.

I love to meet the sun while driving a road trip in a car.     4     (bring) alive in the new sunlight, everything looks promising. It always seems as if it was the first time in your life that you had seen a green leaflet, the trees,     5     grew right next to your car window, and a light smiling over the nature.

Spring and autumn are two seasons of the year that are perfect for a road trip. In my opinion, spring is the most inspiring time of the year,     6     when you open the car windows, you can actually feel that the world is clean and ready for a new life. The green grass is so fresh that you can’t wait     7     (take) a deep breath. The air is filled with a fragrant smell of the plants.

A road trip in autumn is beautiful, too. The golden brush touches     8     around the gardens, the fields, the groves, the woods. In deep autumn, the whole earth     9     (cover) by colorful plants as if you were driving through a fine carpet. The air is sharp, cool and fresh. You simply put on a warmer sweater but never put the window up!

A road trip for me is the moment of communication with nature. It is a dialogue     10     the nature and me. The beauty that you observe during a car road trip purifies you, refreshing your soul and your mind!
