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 . 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 . 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.

5 . 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.

6 .

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 . The “reading wars,” one of the most confusing and disabling conflicts in the history of education, went on heatedly in the 1980s and then peace came. Advocates of phonics (learning by being taught the sound of each letter group) seemed to defeat advocates of whole language (learning by using cues like context and being exposed to much good literature).

Recent events suggest the conflict of complicated concepts is far from over. Teachers, parents and experts appear to agree that phonics is crucial, but what is going on in classrooms is not in agreement with what research studies say is required, which has aroused a national debate over the meaning of the word “phonics.”

Lucy M. Calkins, a professor at Columbia University’s Teachers College and a much-respected expert on how to teach reading, has drawn attention with an eight-page essay. Here is part of her argument: “The important thing is to teach kids that they needn’t freeze when they come to a hard word, nor skip past it. The important thing is to teach them that they have resources to draw upon, and to use those resources to develop endurance.”

To Calkins’s critics, it is cruel and wasteful to encourage 6-year-olds to look for clues if they don’t immediately know the correct sounds. They should work on decoding — knowing the pronunciation of every letter group — until they master it, say the critics, backed by much research.

Calkins’s approach “is a slow, unreliable way to read words and an inefficient way to develop word recognition skill,” Mark S. Seidenberg, a psychologist at the University of Wisconsin, said in a blog post. “Dr. Calkins treats word recognition as a reasoning problem — like solving a puzzle. She is committed to the educational principle that children learn best by discovering how systems work rather than being told.”

Many others share his view. “Children should learn to decode — i.e., go from print on the page to words in the mind — not by clever guesswork and inference, but by learning to decode,” Daniel Willingham, a psychologist at the University of Virginia, told me. He said the inferences Calkins applauds are “cognitively (认知地) demanding, and readers don’t have much endurance for it. … It disturbs the flow of what you’re reading, and doing a lot of it gets frustrating.”

Yet a recent survey found that only 22 percent of 670 early-reading teachers are using the approach of phonics and what they mean by phonics is often no more than marking up a worksheet.

Both sides agree that children need to acquire the vocabulary and background information that gives meaning to words. But first, they have to pronounce them correctly to connect the words they have learned to speak.

Calkins said in her essay: “Much of what the phonics people are saying is praiseworthy,” but it would be a mistake to teach phonics “at the expense of reading and writing.”

The two sides appear to agree with her on that.

1. Critics of phonics hold the opinion that ________.

A．children should be taught to use context

B．teaching phonics is both boring and useless

C．kids acquire vocabulary in hearing letter groups

A．Tell me and I will forget; show me and I will remember.

B．Skilled reading is fast and automatic but not deliberative.

C．Word recognition skill should be developed in problem reasoning.

D．Learning to make reasonable inferences is also a way of decoding.

3. It can be inferred from the passage that ________.

A．phonics approach has been proved to be successful

B．children don’t shy away from difficulties in reading

C．the two reading approaches might integrate with each other

D．reading and writing are much more important than phonics

4. Which of the following might be the best title of the passage?

A．An everlasting reading war among critics

B．From print on the page to words in the mind

C．A battle restarts between phonics, whole language

D．Decoding and inferring confuse early-reading teachers

8 . 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.

9 . 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.

2. What has actually led to the rise of electricity prices?

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.

3. Why could an unusually cold winter make the gas market tighter?

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.

4. What can we learn from James Huckstepp’s words in the last paragraph?

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.

10 . 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.
