1 . We Need to Think about Conservation on a Different Timescale

Time, perceived by humans in days, months, and years, contrasts with nature’s grander scales of centuries and millennia, referred to as “deep time.” While paleontologists (古生物学者) are trained to think in deep time, conservationists are realizing the challenges it poses. Shortsightedness about time limits modern conservation, with efforts often overlooking past healthy conditions of ecosystems in the context of climate and biodiversity crises.

The shifting baseline syndrome (综合症), where standards in a place change gradually, makes conservation more complex. It involves evaluating ecosystems primarily on their recent past, often with negative consequences.

Recent shifts in California’s forest management practices, from stopping fires to embracing Indigenous knowledge of controlled burns, exemplify the importance of understanding historical ecosystem dynamics. To enhance conservation, adopting a deep-time approach is crucial.

Modern mathematical modeling, combined with long-term data, offers a pathway for preserving ecosystems. In California’s kelp (海带、海藻) forest, researchers identified an overlooked keystone species — the extinct Seller’s Sea Cow (大海牛). By examining past kelp forests, a deeper story impacting regeneration was revealed. The sea cow, a massive plant-cater, contributed to a diverse, vital undergrowth by trimming kelp and letting light reach the area.

The researchers put forward a novel approach to kelp forest restoration: selectively harvesting kelp, imitating the sea cow’s impact. This strategy, considering historical dynamics, challenges assumptions about recent ecosystems and offers new conservation methods.

Rather than only focusing on removing urchins (海胆) or reintroducing sea otters, the researchers suggest employing teams of humans to selectively harvest kelp, as the Steller’s sea cow once did, to encourage fresh growth. This sustainable harvest could benefit both the ecosystem and human consumption.

In short, assumptions based on the recent past may impede the understanding and protection of ecosystems. On the other hand, the application of controlled burns, similar modeling studies, and a deep-time perspective (视角) could significantly transform conservation efforts. Recognizing our role in an ongoing narrative spanning millions of years is essential, urging a comprehensive understanding of ecosystems through time. Embracing this role is crucial for shaping the future and establishing vital connections from the past to the future.

2 . 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.

3 . 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.

4 . The environmental practices of big businesses are shaped by a fundamental fact that offends our sense of justice. A business may maximize the amount of money it makes by damaging the environment and hurting people. When government regulation is effective, and the public is environmentally aware, environmentally clean big businesses may out-compete dirty ones, but the reverse is likely to be true if government regulation is ineffective and the public doesn’t care.

It is easy to blame a business for helping itself by hurting other people. But blaming alone is unlikely to produce change. It ignores the fact that businesses are not charities but profit-making companies, and they are under obligation to maximize profits for shareholders by legal means.

Our blaming of businesses also ignores the ultimate responsibility of the public for creating the conditions that let a business profit through destructive environmental policies. In the long run, it is the public, either directly or through its politicians, that has the power to make such destructive policies unprofitable and illegal, and to make sustainable environmental policies profitable.

The public can do that by accusing businesses of harming them. The public may also make their opinion felt by choosing to buy sustainably harvested products; by preferring their governments to award valuable contracts to businesses with a good environmental track record; and by pressing their governments to pass and enforce laws and regulations requiring good environmental practices.

In turn, big businesses can exert powerful pressure on any suppliers that might ignore public or government pressure. For instance, after the US public became concerned about the spread of a disease, transmitted to humans through infected meat, the US government introduced rules demanding that the meat industry abandon practices associated with the risk of the disease spreading. But the meat packers refused to follow these, claiming that they would be too expensive to obey. However, when a fast-food company made the same demands after customer purchases of its hamburgers dropped, the meat industry followed immediately. The public’s task is therefore to identify which links in the supply chain are sensitive to public pressure.

Some readers may be disappointed or outraged that I place the ultimate responsibility for business practices harming the public on the public itself. I also believe that the public must accept the necessity for higher prices for products to cover the added costs of sound environmental practices. My views may seem to ignore the belief that businesses should act in accordance with moral principles even if this leads to a reduction in their profits. But I think we have to recognize that, throughout human history, government regulation has arisen precisely because it was found that not only did moral principles need to be made explicit, they also needed to be enforced.

My conclusion is not a moralistic one about who is right or wrong, admirable or selfish. I believe that changes in public attitudes are essential for changes in businesses’ environmental practices.

5 .

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.

1. Many Bronze Age coins were made into the shape of a spade because ___________.

3. What does the underlined word “indispensable” in Paragraph 5 probably mean?

A．Flexible.

B．Essential.

C．Wasteful.

D．Alternative.

4. Which of the following would be the best title for the passage?

A．What Coins and Computers Bring Us

B．How Agriculture Loses to Digital Industry

C．How Bronze Age Develops to Information Age

D．What Ancient Money Tells Us About the Future

6 . We’ve dug deep to find 4 of the most exciting documentary films coming to a screen near you in 2022.

Last Exit: Space

Last Exit: Space, narrated by Werner Herzog, explores the human potential for settling in space and sending people where they’ve never been before. Since planet Earth is possibly going to hell (地狱) in a handbasket, the film promises to ask the question: where else might we call home? Directed by his son Rudolph Herzog, Last Exit: Space will be available from March 10 on Discovery.

Gorbachev. Heaven

As leader of the Soviet Union Mikhail Gorbachev was once one of the most powerful people on the planet who governed a landmass so big that it covered 11 time zones. Gorbachev’s legacy is a complex one — he oversaw the end of the Cold War but many Russians blame him for the Soviet Union’s collapse. The BBC says this potentially fascinating look at one of the most significant figures from inside his own home will be airing in the very near future.

We Met In Virtual Reality

This film from director Joe Hunting beats fresh ground in that it is filmed entirely in virtual reality. Less about the technology itself, it is more an exploration of human connections and how these can develop in the 3D virtual world. Early reviews have been positive following its showing at Sundance. Expect a streaming release in late May this year.

2nd Chance

Hold your popcorn tightly when watching this. If the trailer (预告片) is anything to go by, there are going to be lots of near-death moments. 2nd Chance from Oscar-nominated director Ramin Bahrani tells the story of Richard Davis, the wild and odd inventor of the modern bullet-proof vest. “All will be revealed as soon as a release date is confirmed.” Ramin Bahrani promised on April 5^th.

1. What is probably the major concern in Last Exit: Space?

A．Space travel is difficult for people.

B．Human beings may go to hell after death.

C．Human beings can’t find their way back from space.

D．The earth will become unfit for human habitation.

2. Which documentary film suits people who are interested in studying history?

A．Last Exit: Space.	B．Gorbachev. Heaven.
C．We Met In Virtual Reality.	D．2nd Chance.

3. In which section of a magazine can you find this text?

A．Science & Technology.	B．Fashion & Beauty.
C．Culture & Entertainment.	D．Travel & Adventure.

7 . 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.

2. What did Sayers imply about education?

A．It was boring.	B．It was worrying.
C．It was conventional.	D．It was useless.

3. What does the underlined word “distortions” in paragraph 3 refer to?

A．Popular news.	B．Various evaluations.
C．Persuasive arguments.	D．Misleading information.

4. Why does the author write the text?

A．To review a book.	B．To introduce a writer.
C．To suggest a practical skill.	D．To criticize social media.

8 . “You’d be an intermediate (中级学生),” the clever salesgirl at the Apple Store said brightly. She was talking about the free classes one could sign up for. An intermediate, I thought with pride. “I’ve used Macs since they had green text and discs,” I said, eager to strengthen my position. “And I had a Mac Classic for years.” She smiled, or maybe she was thinking, “If it’s been that long, why are you still an intermediate?”

Why does one remain an intermediate? Sometimes it’s a matter of opportunity: Leaving New England was a blow to my cross-country skiing. No longer living on the banks of a river held up kayaking. Horseback riding, too, requires an opportunity. I know, however, a friend I rode with as a child bought herself a retired police horse in her 40s. A devoted kayaker would not have been prevented by the highways lying between her and rivers.

Sometimes, it’s ability. I have taken up piano later in life. I love music, but I can see that I have no particular gift for it. Gardening was another late job. I wasn’t a natural at that, either.

I admit I’m a little ashamed of being an intermediate. It seems to imply a lack of focus, an unwillingness to push myself to go deeper or further. Do I lack the persistence to become an expert? Am I too easily distracted to put in the 10,000 hours reportedly required to achieve mastery?

Maybe I have to accept that, for now at least, intermediate is my sweet spot. I’ve moved past the frustrations of beginnerhood without meeting the demands of expertise. A beginner is a beginner and an expert is just that. But an intermediate can be low, medium, or high. And wherever you are as an intermediate, you can always go forward, try harder, and learn more.

Who of us can claim to be an expert parent, wife, husband, child, or friend? At best, we’re the high intermediate with much to learn.

1. What did the writer want to prove to the salesgirl in the first paragraph?

A．Her position as a lifelong intermediate.

B．Her good knowledge about Apple computers.

C．Her eagerness to attend free courses.

D．Her ability to afford to buy expensive computers.

2. What did the writer think of opportunities?

A．They are only excuses.

B．They appear just by accident.

C．They are waiting in our life.

D．They just come and go.

3. What do the questions express in Para. 4?

A．The writer’s worries.

B．The writer’s disappointments.

C．The writer’s curiosities.

D．The writer’s doubts.

4. Why is the writer content to be an intermediate?

A．It means the possibility to make improvement.

B．It marks the beginning to achieve mastery.

C．It presents the opportunity to become an expert.

D．It rids people of the difficulty to move on.

9 . What is volunteer travel?

Volunteer travel involves taking a trip where all or part of the purpose of the trip is to participate in an arranged service opportunity helping others. Typically, the volunteer activity takes place in a foreign country, but some opportunities can involve national or regional projects.     1    

Charitable interests often go far beyond national boundaries. People in developed countries become interested in the struggles of people in less developed countries.     2     Volunteer travel is a way to combine a visit to a new location with meaningful work that has a direct impact on communities in other parts of the world.

    3     Historically, church groups made up a large part of this market. Once a year a religious organization or church would organize a trip to another country.     4     For example, it would be to help build a school in an impoverished(贫困的)area, or dig wells so a village would have clean water, or engage in hundreds of other projects that would impact those less fortunate. As international travel became easier and the Internet made communication between countries much easier, the interest in volunteer travel increased.

    5     Volunteering in other countries has become as accessible as browsing a website and signing up. Instead of traveling with a group that is organized at the volunteers home base, the volunteer may join a group that gathers at the worksite from all over the world. This sort of volunteer travel is sometimes referred to as voluntourism or vacanteerism.

A．The primary purpose of the trip was very specific.

B．This type of travel has been an option for many years.

C．Educational institutions also made volunteer travel an option.

D．Sometimes, donating money is not enough to satisfy the need to help.

E．The Internet has helped make community service in general more popular.

F．These trips are usually arranged by church organizations, human interest groups or non-profits.

G．A new trend is that for-profit tour operators arrange group travel around volunteer opportunities.
