1 . Three scientists jointly won this year’s Nobel Prize in physics for proving that tiny particles (粒子) could keep a connection with each other even when separated, a phenomenon once doubted but now being explored for potential real-world applications such as encoding information. Frenchman Alain Aspect, American John F. Clauser and Austrian Anton Zeilinger were quoted by the Royal Swedish Academy of Sciences for experiments proving the “totally crazy” field of quantum entanglements (量子纠缠) to be all too real. They demonstrated that unseen particles, such as photons (光子) , can be linked, or “entangled”, with each other even when they are separated by large distances.
In quantum entanglement, establishing common information between two photons not near each other “allows us to do things like secret communication, in ways which weren’t possible to do before”, said David Haviland, chair of the Nobel Committee for Physics. Quantum information “has broad and potential effects in areas such as secure information transmission, quantum computing and sensing technology”. The kind of secure communication used by China’s Micius satellite, as well as by some banks, is a “success story of quantum entanglement”, said Harun Siljak of Trinity College Dublin.
The Nobel Committee said Clauser developed quantum theories first put forward in the 1960s into a practical experiment. Aspect was able to correct an error in those theories, while Zeilinger demonstrated a phenomenon called quantum teleportation that effectively allows information to be sent over distances. “Using entanglement you can send all the information which is carried by an object over to some other place where the object is.” Zeilinger said. He added that this only works for tiny particles. “It is not like in the Star Trek films transporting something, certainly not the person, over some distance,” he said.

4 . Polly Arrowsmith is a clever bargain shopper, and knows exactly when her three local supermarkets make their daily price down. She estimates that hunting out food with yellow discounted labels saves her hundreds of pounds a year. But all this could soon be coming to an end. That’s because supermarkets are adopting dynamic pricing, controlled by artificial intelligence (AI) software.
It involves digital price tags that are displayed either on the shelf below the food items, or on high-tech labels attached the product itself. These prices are automatically, and wirelessly, updated by the AI when a particular item approaches its sell-by date. The AI also examines how much stock (库存) the store is holding of that item and makes the decision as to whether a markdown is requiredor not. Besides, it can help supermarkets better understand how to manage stock supply and avoid over-ordering. So we’re actually turning the current food waste problem into an opportunity and can help cut supermarkets’ food waste by more than a third.
Matt Wills, the co-founder of a firm called Acumen, warns that there are potential disadvantages to dynamic pricing. “Not knowing what the reference price is, consumers might not realise they are getting a deal at all,” he says. “This could also cause added complications for people who retired, if items are seen to be continually changing in price.”
The key, Mr. Wills believes, will be for supermarkets to have strict guidelines to ensure they can offer the benefits that dynamic pricing can bring, while ensuring AI doesn’t create unintended negative consequences for shoppers. Whether shoppers will welcome the change is another question, but Mr. Wills believes they’ll be won over by the price reductions they receive.
Ms. Arrowsmith admits she will miss the yellow discount stickers that have become part of her shopping routine. However, she also says she wants to see less food going to waste. “I’m happy to forgo really cheap pricing,” she says.

5 . Mr. Riccardi was working for an Italian university at the time, 10 years ago, and had to go to the city of Potenza in the south of the country for a conference. He wanted to book an environmentally-friendly hotel, but it was not so easy to find one online and book.
So it gave him the idea for a business — a website called Ecobnb, where people can search for sustainable accommodation. When someone finds a place that they would like to book, Ecobn b does not take the payment. Rather it contacts the property, which then emails the person directly. Ecobnb makes its money by charging the accommodation providers a monthly subscription to list on its website.
Today Ecobnb, based in Trento, in northern Italy, lists more than 3,000 properties worldwide, from an organic farmhouse in Tuscany, to an eco-mountain cottage in Costa Rica. 2.8 million travellers now use Ecobnb per year, up from 780,000 in 2018. Mr. Riccardi says the number is still rising. Some accommodation providers offer discounts for guests arriving by bicycle, or those not using a car during the trip.
“Holidaymakers are rethinking their relationship with planet Earth,” Mr. Riccardi says. “Thereis a new awareness, especially in young people, about our responsibility for our future and for the planet.” Statistics appear to back this up. A study has found that 69% of travellers are now actively seeking sustainable travel options.
Although Ecobnb is focused on sustainability, how sustainable is it when many people might be flying to arrive at the accommodations it lists? “The impact of the travel of the flights is very big,” agrees Mr. Riccardi. “We are pushing the staycation (就近旅游) model a lot, inviting people to discover their own countries and to avoid the flights when it’s possible.”
“More people are interested in green lifestyles every day,” he says. “And now they are looking for the same green choices also during their holidays. These little choices can come together, and we can change things and make something different. We can be the change we want to see in the world.”
1. What inspired Mr. Riccardi to start the website Ecobnb?A.His pursuit for a better future. | B.His motivation to find a green hotel. |
C.His teaching experience in an university. | D.His desire to invest in sustainable tourism. |
A.It enjoys great popularity. | B.It owns 3,000 properties in Italy. |
C.It offers discounts to all visitors. | D.It charges payment from customers. |
A.To promote sustainable travel. | B.To attract more young travelers. |
C.To reduce the accommodation list. | D.To make flights available for others. |

“My wife and I moved to Maple Estate when we got married. For a few months, we spent all our free time after work doing up our house. Even though we knew that our neighbours were friendly and would sometimes invite us for their gatherings, we were occupied with getting things ready. However, it wasn’t long before we grew curious about the Community Day celebrations. After we started attending them regularly, we met many neighbours. The first time we invited some of them over, we played games that helped us to get to know one another better!”
—Mr. Wang, a Maple Estate resident since 2022

8 . The deep and dark night sky is filled with wonder. Looking up at the bright stars, mysterious planets and ancient constellations (星座) brings a timeless feeling. Today, populated areas around the globe are enveloped in a type of fog that disconnects people from that amazing night sky, but reducing light pollution can help to restore the wonder.
After the sun sets, cities and suburbs across the globe are lit up with artificial lights. They glow along roads and highways and flood fields in sports stadiums. They also shine light on skyscrapers, malls, and flashing electronic signs. However, these lights negatively impact wildlife.
Artificial lighting has caused the firefly population to completely disappear in some areas, while lighthouse beams (光线) negatively impact marine species. In fact, in the US and Canada, 18 species of firefly are now classified as being threatened with a high risk of extinction in the next ten years.
Just leaving that light on affects the behavior of nocturnal pollinators (夜间传粉者) like moths, causing them to fly towards the light and not the flowers. This, in turn, negatively affects plants’ abilities to bear fruit and reproduce.
Many people are aware of many types of pollution including air, water, and land, but few realize that strong artificial lighting is harmful to all mammals, including humans. In order to make people aware of the importance of darkness, researchers wrote a world atlas (地图册) of artificial night sky brightness, which is published in Science Advances. Their findings reveal that 80 percent of the world populations live under a sky glow, with more than 99 percent of Americans and Europeans living under light-polluted skies.
Although individuals cannot control the highway and city lights, they can make a difference at home. And if everyone were to “turn off the switch”, it could help to bring back natural darkness in some areas. Light areas where light is needed and aim the light beams downwards. Try to use low-level lighting and be aware that some surfaces reflect more light into the sky.
1. What does the author mainly want to say in paragraph 2?A.Light pollution is actually widespread. |
B.Artificial lights bring people convenience. |
C.The use of artificial lights should be cut down. |
D.The night sky is beautifully lit up with those lights. |

9 . Women’s sport is experiencing growth. This season, the Allianz Premiership Women’s Rugby (PWR) league kicked off with a campaign to transform ideas of women’s rugby. Here are the stories of four remarkable women who are powered differently — born to break the stereotypes (刻板印象).
Abbie Ward, 30, Bristol Bears
Abbie has marked a successful return to the rugby field this season playing her first match since the Rugby World Cup Final in November 2021, just four months after giving birth to her daughter, Hallie. Abbie’s journey showcases a ground-breaking shift in the sport’s approach to motherhood. Abbie is eager to integrate Hallie into her playing life, maintaining a balance between being a mother and a professional sports person.
Jodie Ounsley, 22, Exeter Chiefs
Jodie attracts audiences as a deaf athlete. As the first deaf person to be selected for the England 7s squad, she in 2020 won Young Deaf Sports Personality of the Year. Jodie detailed, “I’ve had parents messaging me saying ‘My daughter with a cochlear(耳蜗的) implant hasseen you online playing rugby, and wants to do it, too.’”
Rachel Lund, 29, Gloucester-Hartpury
Rachel is a proud member of the “dual career club”, a nickname Rachel has given to the PWR players taking other regular jobs around their training and match days. She devotes herself to a full-time role as a physiotherapist (理疗师) with her commitment to female sport extending beyond the field. According to Rachel, “Research on female health is minimal at best. I’m keen on improving female health.”
Amanda Swartz, 23, Leicester Tigers
Amanda’s journey from a professional figure skater to a professional rugby player shows the determination that defines her athletic journey. Seeking a new challenge beyond skating, she discovered rugby. The discipline and goal-oriented drive experienced during her figure skating days became invaluable in her rugby change. Amanda has accepted her new sporting path and takes pride in promoting the visibility of rugby in Sweden.
1. Who is a disabled player?A.Abbie Ward. | B.Jodie Ounsley. | C.Rachel Lund. | D.Amanda Swartz. |
A.She focuses on female health. | B.She was fired by the former team. |
C.She has just given birth to a baby. | D.She was a professional figure skater. |
A.They experience a tough life. |
B.They have the same athletic journey to rugby. |
C.They change people’s view of women’s rugby. |
D.They urge women to improve their mental health. |
10 . How to Make Your Writing Flow?
Writing flow refers to how smoothly text flows from one sentence to the next and one paragraph to another.
1. Vary your sentence structure.
Using only short, choppy sentences creates a disconnected rhythm that disrupts the flow, while a series of long, complex sentences overwhelm readers.
2. Use transition words and phrases.
Transition words and phrases act like bridges between sentences and paragraphs. They create logical connections between ideas. Use transitions like “however,” “therefore,” “similarly,” and “in contrast” to glue sentences and paragraphs together smoothly.
3. Structure paragraphs around a central idea.
4.
Revisiting writing with fresh eyes makes flaws in flow and transitions more noticeable. Let your drafts rest for a day or two to prevent getting stuck reworking the same passage repeatedly. Approaching writing anew allows you to evaluate flow and smooth out imperfections with distance and objectivity.
A.Don’t leave out the revising process. |
B.Let completed drafts rest before editing. |
C.The key is to mix sentence lengths to create fluid variety. |
D.Place them at the beginning of a sentence or between independent clauses. |
E.Flowing writing maintains the continuity of ideas and transitions logically. |
F.Each paragraph should have a controlling idea relating to your overall theme. |
G.As a writer, it is your responsibility to present your readers with a central idea. |
