1 . These days, there’s barely a world leader who doesn’t talk up science. For example, the India’s Prime Minister was the main performer at the annual Indian Science Congress, held in Nagpur, where he encouraged the nation’s researchers to do the science needed to make India self-reliant.
The message to researchers is crystal clear: leaders see science as essential to national prosperity, well-being and, of course, competitiveness. So, is research fit for the challenge of advancing, refining or critiquing these goals? Not exactly. And it won’t be until there is fundamental reform to the gateway to a research career: PhD training.
As Nature and other publications have frequently reported, PhD training worldwide has been in trouble for some time. Students’ stipends (生活津贴) are not enough in most countries, creating a cost-of-living crisis. Early-career researchers constantly report concerns about a constant lack of support and poor-quality supervision, with senior researchers rarely trained in mentorship (指导).
Furthermore, PhD candidates are inadequately prepared for the cross-disciplinary working and large teams that characterize cutting-edge science today. This is especially true for careers outside academic research, where the overwhelming majority of PhD candidates will be heading.
It is not all bad. Universities in a small number of high-income countries have reformed, or are reforming, PhD assessment. But in most places, and especially in low- and middle-income countries, a candidate’s work is still evaluated using a single-authored paper. In many countries, candidates must publish in a journal before they get a PhD, something that critics say could fuel profitable publishing.
The system’s strains have become more obvious because the number of people doing PhD training has been rising sharply. According to the 2022 book Towards a Global Core Value System in Doctoral Education, the number of PhDs awarded in India increased from 17,850 in 2004 to 25,095 in 2016; US figures climbed from 48,500 to 69,525 over the same period. If researchers are to meet society’s expectations, their training and mentoring must escape the nineteenth century.

3 . Like many people, in terms of socializing, I prioritize (优先考虑) making time for my closest friends and family. When it comes to reaching out to people, I don’t know as well I often find myself unwilling to engage. This could be a big mistake, though, according to a new study. Having different types of social interactions seems to be central to our happiness —something many of us may think little of.
In a series of surveys, researchers looked at how having a socially diverse network related to people’s well-being. In one survey, 578 Americans reported on what activities they had been engaged in, with whom and for how long over the past 24 hours, while also saying how happy with life they were. The researchers found that people with more diverse social networks were happier and more satisfied with life than those with less diverse networks — regardless of how much time they had spent socializing overall.
“The more you can broaden your social circle and reach out to people you talk to less frequently —like an acquaintance, a friend, a coworker, or even a stranger —the more it could have positive benefits for your well-being,” said the lead researcher Hanne Collins of Harvard Business School.
To further test this idea, she and her colleagues looked at large data sets from the American Time Use Survey and the World Health Organization’s Study on Global Aging and Adult Health. In both cases, they found that when people had a broader range of social interactions, they experienced greater happiness and well-being.
Then Collins and her colleagues did another analysis, using data from a mobile app that 21,644 French-speaking people used to report on their daily social activities and happiness. There, they found that when someone experienced greater-than-average social diversity one week, they were happier that week and the week after.
Why is that? It could be that being with different people contributes to different kinds of emotions, which may be a driving force in our happiness, says Collins. Alternatively, it could be that having a more diverse network allows you to get various social supports when you need it. Whatever the case, Collins hopes her research will inspire people to expand their social networks when they can.

4 . In much of the western United States, drought and access to fresh water is a critical issue. However, recently California came up with a novel solution. The state approved regulations that allow agencies to purify wastewater for drinking. This recycled wastewater may be consumed in homes, schools, and businesses.
As the population in California has exploded in recent decades, the state has struggled to meet demands for fresh water. Recycled wastewater will allow the state to increase access to the precious resource.
Recycled wastewater is not new to the state. It has previously been used in ice hockey rinks (冰球场), for crops, and to generate artificial snow. But now, water agencies will have the option to put recycled wastewater back into pipes for drinking. California is only the second state to allow purified wastewater to be consumed. The first was Colorado in 2022.
While the idea of drinking recycled wastewater may be off-putting, regulators spent more than a decade developing rules and regulations to ensure safety. Independent panels of scientists also reviewed the state’s rules around recycled wastewater consumption. All water will be treated for pathogens (病原体) and viruses before being available for consumption.
So far, the state’s plan has been met with approval from large water agencies. Many of them have plans to construct wastewater recycling plans over the next few years. In Southern California, the Metropolitan Water District of Southern California has set a goal aiming to produce 150 million gallons of direct and indirect recycled water per day. This water will be in the pipes of the 19 million people throughout the six counties that the agency serves.
Officials are aware that a certain amount of public convincing may still be necessary. However, they remain optimistic about the future of the project, reminding consumers that the water is safe, and that recycled water is already in use in California.

6 . It’s commonly acknowledged that our lives are ruled by algorithms (算法), but have we really collectively understood how they have transformed our culture and personality?
In Filterworld: How algorithms flattened culture, Kyle Chayka argues convincingly that the rise of algorithm-driven feeds, used everywhere online from Instagram to Spotify, has led to a more uniform culture. Our tastes and desires increasingly don’t belong to us, but to algorithms that are designed to keep people engaged at all costs. If the collection of our tastes truly shapes our entire personality, then this loss is more psychologically damaging than it first appears. Aimlessly scrolling (滚屏) through Netflix or TikTok may seem harmless, but over days, months or years, we lose touch with what we like and enjoy.
Taste-making algorithms are inescapable. Chayka shows this by working through all corners of life: what we wear(TikTok), where we eat(Google Maps), music we listen to(Spotify), even who we date or marry(Tinder). This universe of algorithm-driven decisions has society-wide implications: “It extends to influence our physical spaces, our cities, and the routes we move through…flattening them in turn.” No one gets out of the Filterworld untouched.
If you’re lucky enough not to need any sort of algorithm-based system for your work, then you have the option to step back from algorithms for a while. But if your friend suggests a film recommended on X/Twitter or you feel the need to buy those shoes suddenly everyone has started wearing after social media advertisements, what are you to do? It all feels fruitless.
This Filterworld may be inescapable, but there is hope. You can start by engaging more with the media you do choose to consume. This could mean reading up about a film you watched or paying artists you like directly. Even the thoughtful act of recommending an album (专辑) to a friend is more rewarding than a random TikTok feed. As Chayka says, resistance to algorithms “requires an act of willpower, a choice to move through the world in a different way.”
1. What is Kyle Chayka’s opinion on algorithms?| A．They improve our tastes. | B．They make our culture more alike. |
| C．They help to identify our personality. | D．They contribute to psychological problems. |
| A．The society with advanced technology. | B．The world without social media platforms. |
| C．The network of algorithm-driven decisions. | D．The community free from algorithmic influence. |

7 . Airlines already place common-sense limits on young passengers. For example, on United Airlines, babies younger than seven days old can’t fly. And lately, there’s been a heated discussion about keeping little ones out of business class. Why draw a line there?
No one’s suggesting a ban on babies, or even kids, from flights. That wouldn’t make sense for passengers or airlines. Banning children from flights would be a financial disaster for airlines. That’s because leisure travel accounts for two-thirds of all air travel incomes, and people sometimes take their kids on vacation with them despite their kids’ screams, tantrums (发脾气) and meltdowns.
But maybe it’s time for a little course correction when it comes to children. Maybe there are places we should keep baby-free, such as a section of the plane, or the entire plane. It will benefit passengers because all or some of them will arrive at their destinations well-rested and ready for their vacation or work.
There are some passengers who believe airlines shouldn’t restrict young passengers from flying anywhere. They think people seem to forget that babies and toddlers are people. Restricting children may be an easy solution, but it will have long-term consequences. They’re not going to like the humans they grow up to be.
There’s an equally convincing argument that we should place sensible limits on babies. Some may have physiological challenges that make a flight unbearable. Others may not have the patience to sit in a pressurized aluminum tube for hours. Some of them are just not ready to sit still for a 12-hour flight. But the biggest challenge for babies and toddlers is the pressure changes on the climb to and fall from cruising (平稳行驶的) altitude.
Babies will keep flying anyway. So there are always a few ways of staying calm when you are seated close to a seat-kicking child who raises the noise level on your next flight, for example, asking a flight attendant for help, buying a good pair of noise-canceling headphones or earplugs or avoiding the babies entirely by booking the red-eye flights.

8 . “In the United States, 40 million Americans are food insecure. They don’t know where their next meal is going to come from,” said Aidan Reilly, who co-founded Farmlink. “Meanwhile, in the United States we’re throwing out over 100 billion pounds of food every year.”
Started during the hard period in spring 2020, Farmlink was initially supposed to help struggling families and food banks. Reilly and his childhood friend James Kanoff were reading and watching news about food shortages, and they learned that local farms were forced to destroy spare produce that they couldn’t sell, especially with restaurants, schools and hotels closed. Reilly, Kanoff and a group of friends worked together over Zoom, text and e-mail to contact farms. They didn’t really set out to start a nonprofit then but just thought it would be great to figure out one way to help starving (饥饿的) people.
With “we’ll come to you” as their catchphrase, the group rented trucks and attempted to do all the food pickup and deliveries themselves. They had a lot of difficulties in the beginning, but they made it work, moving more than one million pounds of produce from farms to food banks within just two months and transforming their project into a massive logistics operation in the process. Word spread, and more and more young people at home during the pandemic reached out to help.
Farmlink has worked with more than 100 farms and 300 communities in the United States, rescuing and moving enough food to distribute (配送) more than 64 million meals. “The bigger Farmlink gets, the bigger our worldview gets. There are everyday Americans who live next to us and don’t know how they’re going to feed their kids. And that’s exactly who we’re doing this for,” Reilly said.

9 . Have you ever wondered why most store-bought tomatoes are so tasteless? Does it relate to climate change or soils? The answer has something to do with farmers’ income: Tomato farmers care about output, and the genetic variants (基因变体) associated with output are not associated with tasty tomato flavor, a new study finds.
Is it possible to bring back the rich, sweet flavor of the tomato? To find out, Denise Tieman, research assistant at the University of Florida, explored which genes are associated with tomatoes’ taste.
In an attempt to fix supermarket tomatoes, Florida researchers looked at 398 different types and identified the chemical and genetic makeup of each one. They had participants taste-test 101 varieties, cross-referencing the participants’ favorites with their research findings. They ended up with 13 genetic compositions that are most likely responsible for giving tomatoes their flavor. The researchers then measured the content of the 13 flavor compositions in each of the tomatoes, and identified about250 genetic loci (遗传基因座) that controlled tomato flavor. And the researchers also wanted to explore why supermarket tomatoes have no taste.
It turns out that for industrial growers, it all comes down to priorities (优先性). North American consumers want year-round availability, so farmers started raising their plants for qualities like firmness, shelf life, high output and disease resistance, says Tieman. “Not to discount any of that because it’s all important. We want to have tomatoes in the grocery stores year round and be able to ship them long distances when it’s winter in the north. If they have to be shipped from Florida or Mexico, you need to have all those features.” But as growers planted tomatoes to meet those priorities, the flavor gradually disappeared.
Going back to the old varieties is not an option—at least, not for grocery stores. But the researchers believe that there is hope for a growable tomato that’s both long-lasting and flavorful in about three to five years.

10 . China’s generation-Z is not “lying flat”, an expression forgiving upon hard work, as is often claimed, and making an effort is still the mainstream of a group who believes success should be achieved by solid effort, Chinese officials said at a press conference on Thursday, in response to a question on how younger generations should achieve balance between a lifestyle of “lying flat” in face of great pressure and “involution,” which refers to severe internal competition that does not lead to productivity gains.
“Most Chinese youth hold an optimistic view on the future, and the saying’ lying flat’ is more of a joke to release pressure and express their feelings,” He Junke, a government official said at a press conference on Thursday.
At the press conference, China released the first nationwide whitepaper on youth development titled “Youth of China in the New Era,” which showcased achievements linked to the country’s youth development in the new era and reflected the spirit of younger generation. The whitepaper was also released ahead of the 100th anniversary of the founding of CYLC (共青团).
He said China has attached great importance to deeper issues reflected by talk of “lying flat”, which emerged as young generation is subject to increasing pressure across work, study and life amid China’s unique demographic (人口统计学的，人口学的) structure and highly competitive labor market.
“Some in the younger generation feel confused or lost. In response, authorities have scaled up the amount of support available to help solve their issues in education, employment, marriage and child raising,” He noted, while urging the whole society to support the mental development and psychology of generation-Z.
He pointed out that it is also important for certain young people to realize that it is unrealistic to build a career without taking responsibility and making endeavor. “All happiness is achieved through devoted effort, and making endeavor itself is also a kind of happiness,” He stressed.
1. What is He Junke’s attitude towards “lying flat”?| A．Objective. | B．Subjective. | C．Opposed. | D．Favorable. |
| A．More and more young people choose to lie flat in China, |
| B．Young people face great pressure in their study, work and life. |
| C．China’s population structure affects the supply of labor market. |
| D．The government needs to celebrate the 100th anniversary of CYLC. |
| A．Young people should take responsibility and make efforts to achieve success. |
| B．The whole society should care about young people’s physical and mental health. |
| C．Authorities should help young people and give them support in many aspects of life. |
| D．All of the above. |
| A．To call on a low carbon lifestyle. |
| B．To inform the latest research on the social development. |
| C．To set a goal for the young people who are under pressure on study. |
| D．To address a social problem among young generations in the newer era. |
