1 . 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.

2 . Traditionally, the number of meaningful social relationships one can maintain is around 150. This concept finds its roots in the natural development of the human brain. However, in the digital age, where our social connections extend far beyond the geographical boundaries (界限), we easily create more connections with the help of the rising online platforms. Then, a question arises: Does the digital age rewrite the rules of social connection?
A study published in Cyberpsychology, Behavior, and Social Networking explored the effect of social media usage on the size of social circles and the closeness of relationships. The researchers found that more time spent on social media made for a larger number of online “friends,” but not a larger number of offline friends. Further, the findings were not linked to feelings of closeness towards online or offline friends.
Another study from the European Journal of Information Systems studied the link between social media usage and “social overload” — the feeling that too much of the energy for socializing is being used up by online relationships. The authors found that social media usage directly contributed to the experience of social overload, related to digital tiredness and dissatisfaction with social media.
With social media platforms rising, one’s ability to connect with people challenges the traditional concept. The brain, used to manage a limited number of relationships, now fights against the difficulties of dealing with a large number of digital connections, leading to a less attention and feeling investment (投入) in a relationship. And the online shallow connections can not develop meaningful, lasting relationships that stand the test of digital distance.
Therefore, in the digital age’s social whirlwind, instead of drowning (淹没) in a sea of weak interaction (互动), choose to engage in meaningful conversations and focus on the handful of relationships that truly fit your heart. Hug the beauty of face-to-face connections, allowing the richness of human interaction to flower beyond the digital world. By doing so, we create digital and physical spaces that truly improve our well-being.

| B．It caused the brain to break down and damaged the health. |
| C．It led to expression errors when one socialized with friends. |
| D．It developed shallow connections that stand the test of distance. |

3 . If sales generally feel hard to resist, the sale in front of Arron Schurevich was the ultimate test: a new car just like the one he’d loved. And it was more than a 20% discount. “I figured that I would be a fool not to take advantage of that,” says Schurevich. After he drove the car off the lot, the deal turned sour. The brand-new car quickly needed repairs. Schurevich now jokes that he paid a tax for being a fool.
Why is it so hard for the human brain to resist a discount? Spotting something you’d like to buy activates your brain’s reward circuitry (奖赏回路). It gets especially heightened if it’s something you’ve been fascinated by — say, the same car you’ve enjoyed for years. Additionally, the discount itself often registers as a win, delivering its own kind of joy, says Jorge Barraza, a consumer psychologist at the University of Southern California.
“Not only are we getting the product,” Barraza says, “but we’re also getting that reward that we discovered something; we’ve earned this extra thing.”
Stores, of course, know all this and try to push our buttons. “Limited-quantity, limited-time, scarcity-marketing promotions—they get people’s blood pumping,” says Kelly Goldsmith, who studies this as a marketing professor at Vanderbilt University.
It’s really hard to always approach sales rationally. One buying strategy experts recommend is to make a shopping list in advance and then, stick to it. Another is to research items — beforehand or on the spot, checking online — to weigh whether the sale is really a good deal.
“The human brain has essentially evolved to feel first and think next, which is why you need to give yourself time to cool off from your instant reaction when in front of a sale,” says Goldsmith.

| A．Stores are good at pushing buttons. | B．Stores tend to affect people’s health. |
| C．Stores help consumers earn extra things. | D．Stores know how to attract consumers with sales. |
| A．Calm down in front of a sale. | B．Make a shopping list ahead of time. |

It’s the Saturday, 1:00 am, and Stormy, my dog, and I were going on a pre-dawn bird-watching adventure. The weatherman predicted fog, but as we hit the road, it’s clear. Along our journey, I stopped at a petrol station, ensuring Stormy was safely locked in the truck.
“Stormy, hang tight,” I whispered, stepping out into the night air.
Back on the highway, as we were near the marshlands, a heavy fog began to swallow everything. At a sharp bend, my truck hit soft ground, and I lost control. “Oh, no!” Panic set in as the vehicle slid off the road with a bang, falling down a steep bank and into the water.
In the strange silence that followed, I was floating inside the car, gently carried downstream by the canal. “Come on, door,” I said, switching uselessly at the handle. It won’t move; the electrical system had shorted out due to the water. “I’ve got a glass breaker,” I reminded myself, reaching for the tool in the center part.
With each failed attempt to break the window — the glass bouncing back at me — I felt a growing sense of urgency. Water moved over the floorboards, cooling my feet. “Stormy, stay calm,” I said, lying down to kick at the window with all my strength. But my efforts only met resistance.
As the water level rose threateningly close to the ceiling, fear clawed at my heart. In a last effort, I dived behind the seat for my toolbox. “Got to find something solid.” My hands brushed against the cold metal toolbox, then the fire extinguisher (灭火器). “This might work.”
“Here goes everything,” I thought, holding the extinguisher and hitting it against the window. The impact resounded through the car, but the glass holds firm. “Not yet,” I begged under my breath, as the extinguisher bounced harmlessly away.
The water kept rising, and so did my fear. A voice inside me screamed to give up, but another thought pierced through — Stormy. “For Stormy, I can’t quit.” Just then, I sensed a pause in the water’s rise.
An unspoken sound said, “You have more time. What will you do?”

People don’t usually become homeless suddenly. It’s a chutes-and-ladders (阶梯状) process. A large new statewide study takes a closer look at the period just before homelessness, by asking a representative sample of almost 3,200 homeless people from all over the state about the dilemma they fell into, and what would have helped.
Some of the findings were unsurprising: in the state with the nation’s largest homeless population, people are unhoused because they don’t have enough money, or have experienced trauma (创伤). A quarter of all survey participants had experienced family violence, and their lives and health get much worse once homelessness strikes. But some of the report’s data run counter to popular perception: for example, most homeless people are not from out of state, contrary to the common belief that homeless people move to California for the weather and policies.
The study’s lead author, Dr. Margot Kushel, says there’s a “doom loop” of homelessness, where people have jobs that don’t cover living expenses, so they lose their homes, and the resulting instability makes it harder to keep their jobs.
Kushel points to really exciting models of homelessness prevention, where in low-income communities, they’ll have subway and bus posters saying, “Are you at risk of becoming homeless? Call us.” These programs might offer anything from cash to finding landlords or roommates. “What was really striking to us was how little money people thought it would have taken,” says Kushel. Most participants suggested that less than $500 a month, or a onetime payment of $10,000, would have kept them housed. Kushel cautions that the vast majority of mental health issues among the study participants are anxiety and depression. It’s likely that the lack of resources results in those conditions, rather than the illness causing the homelessness. “The driving issue is clearly the deep poverty,” Kushel says.

8 . With almost all big employers in the United States now using artificial intelligence (AI) and automation in their hiring processes, the public is considering some urgent questions: How can you prevent discrimination in hiring when a machine is keeping the discrimination? What kind of methods might help?
Some 83% of employers, including 99% of Fortune 500 companies, now use some form of automated tools as part of their hiring process, said the Equal Employment Opportunity Commission’s ( EEOC) chair Charlotte Burrows, at a hearing on Tuesday. She said everyone needs to speak up on the debate over these technologies. “The risks are simply too high to leave this topic just to the experts.”
Last year, the EEOC issued some guidance around the use of cutting-edge hiring tools, noting many of their shortcomings. The agency found that resume( 简历) scanners which prioritize keywords and programs which evaluate a candidate’s facial expressions and speech patterns in video interviews can create discrimination. Take, for example, a video interview that analyses an applicant’s speech patterns to determine their ability to solve problems. A person with a speech problem might score low and automatically be screened out. The problem will be for the EEOC to root out discrimination or stop it from taking place.
The EEOC is considering the most appropriate ways to handle the problem. It’s agreed that inspections are necessary to ensure that the software used by companies avoids intentional or unintentional discrimination. But who would conduct those inspections is a more challenging question. Each option presents risks, Burrows pointed out. A third party may turn a blind eye to its clients, while a government-led inspection could potentially stop innovation.
In previous remarks, Burrows has noted the great potential that AI decision making tools have to improve the lives of Americans, but only when used properly. “We must work to ensure that these new technologies do not become a high-tech pathway to discrimination,” she said.
1. What does Burrows suggest people do?| A．Make their own voice heard. | B．Follow the experts’ suggestions. |
| C．Stop using AI in hiring processes. | D．Watch debates about technologies. |
| A．By scanning keywords. | B．By evaluating resumes. |
| C．By analyzing personalities. | D．By assessing speech patterns. |

9 . Parents continuously discuss about how to get their children stronger and tougher, but whatever they do, it’s not working. Cases of anxiety disorders and depression are rising rapidly among teenagers. What are they doing wrong?
The word “antifragile” is invented and used to describe a small but very important class of systems that gain from shocks, challenges, and disorder. The immune (免疫的) system is one of them: it requires exposure to certain kinds of bacteria and potential allergens (过敏原) in childhood in order to develop to its full ability.
Children’s social and emotional abilities areas anti fragile as their immune systems. If parents over protect kids and keep them “safe” from unpleasant social situations and negative emotions, parents deprive (剥夺) them of the challenges and opportunities for skill-building they need to grow strong. Such children are likely to suffer more when exposed later to other unpleasant but ordinary life events, such as teasing and social rejection. It’s not the kids’ fault. Outdoor play and independent mobility went down; screen time and adult-monitored activities went up.
Yet free play in which kids workout their own rules of engagement, take small risks, and learn to master small dangers turns out to be vital for the development of adult social and even physical competence. Depriving them of free play prevents their social-emotional growth. Norwegian play researchers Ellen and Leif warned: “We may observe an increased anxiety or mental disorders in society if children are forbidden from participating in age-adequate risky play.”
They wrote those words in 2011. Over the following few years, their prediction came true. Kids born after 1994 are suffering from much higher rates of anxiety disorders and depression than did the previous generation. Besides, there is also arise in the rate at which teenage girls are admitted to hospital for deliberately harming themselves.
What can parents do to change these trends? How can parents raise kids strong enough to handle the ordinary and extraordinary challenges of life? Parents can’t guarantee that giving primary schoolchildren more independence today will bring down the rate of teenage suicide tomorrow. The links between childhood over protection and teenage mental illness are suggestive but not clear-cut. Yet there are good reasons to suspect that by depriving kids natural anti fragile of the wide range of experiences they need to become strong, parents are systematically preventing their growth. parents should let go—and let them grow.

It was a typical Monday morning. My form teacher, Mrs Tan, was going through our exam questions. I pot down some notes and did my corrections.
“Riiiiiiinnnngg!” A high-pitched sound pierced through the air like a knife. Covering my ears in annoyance, realization dawned on me. It was the fire alarm! While I encouraged others to remain as cool as a cucumber, it was in vain. My classmates were all screaming and running around like crazy.
“Calm down, everyone! Please queue up in an orderly manner! We have practised this in the fire drills!” instructed Mrs Tan , sounding anxious.
The class ignored her and continued screaming at the top of their voices. One student even broke down in a fit of panic. I rushed around the class, asking all my fellow students to settle down while waiting for further instructions.
A serious voice soon announced from the speakers in every class, drawing our attention. “All students are to follow their teachers and evacuate(撤离)the building in a calm and organized manner. The fire may have been caused by a gas explosion in the canteen; do not go near there!”
Mrs Tan finally managed to calm the panicky class down. In a strict voice, she told us that we were to use the evacuation route to Gate 6. She arranged the pupils quickly in neat straight rows and led us out of the classroom.
Upon taking my first step out of the classroom, I took a deep breath instantly. The surroundings were hazy(模糊的) as thick smoke came from the canteen. Choking, I unconsciously covered my nose. To make matters worse, the ash from the smoky surroundings hurt my eyes. Coughing anxiously, I tried to see my teacher in the lead, but the air was too hazy for me to see anything clearly. Within less than a minute, I lost sight of my class and was left alone.
