1 . A few days before New Year 1944, Patricia Krueger received a telegram from the U. S. Army. She hoped it would contain a belated birthday greeting from her husband, an army flight engineer, Charles Krueger, whom she had not heard from for 2 weeks. Instead, the message said he wasn’t coming home: His B-29 had been lost and he was later declared MIA (missing in action). Their son, John Krueger from Middleton, Wisconsin, is still in tears when he recounts this story.
Decades later, the military continues to work to bring back the remains of soldiers like Charles Krueger. The job of finding them falls to DPAA (Defense POW/ MIA Accounting Agency), created in 2015 after critics charged that the previous MIA search process was slow, and behind on innovations in science and technology. Between 1973 and 2014, the remains of only 1,849 missing service member s were returned to their families; in 2021, the agency accounted for the remains of 141 MIAs; according to DPAA figures.
To accelerate the work, Congress gave DPAA the authority to develop public-private partnerships with scientists and groups outside the government. “Teaming up with academic scientists introduces new ways of thinking,” says military historian Michael Dolski. “Working with partners allows us to tap into their technologies and capabilities in ways that we just can’t maintain.”
For scientists, the work is more than technically satisfying. “It’s the most rewarding aspect of my career,” says Mires, a scientist working with the agency. “In other archaeology sites I’ve worked on, the history is remote,” he says. “Here, you’re doing something not for a thing, but for a person, and all the people they touched.”

2 . With the rapid development, the city of Chongqing is becoming more and more attractive to outsiders, including foreigners. For 26-year-old Moldovan Gabriela Cojocaru, who has the Chinese nickname Li Xiaoxiao, Chongqing is the beginning of a dream.
In September 2014, Xiaoxiao, who has studied ethnic dance and ballet since childhood, graduated from the Moldovan National Dance Academy, and several classmates joined her on a trip to China. However, she did not know any Chinese or even English. She made many friends from China, which gradually solved her obstacles in language communication and made herself better adapted to life in China.
“I think as a foreigner, first you have to learn Chinese,” she said. “Then you can go to better understand the culture and the Chinese people.” But after learning what she thought was Chinese, she discovered that the language she had spent two years learning is actually the Chongqing dialect. Such is her delivery that even a Chongqing local would be hard to tell that she is a foreigner by just hearing her voice. As Xiaoxiao thought Chongqing dialect was standard Chinese, she took considerable efforts to be good at it. This “mistake” has turned out to be a lucky strike.
But she is more interested in doing something that helps the two countries understand each other. As such, she introduced Chinese food or Chongqing food, and stories about China to her friends in Moldova. She plans to introduce the history and specialties of Moldova, such as Moldo van wine, to the Chinese. She hopes to let more people know that this country actually has a rich history of more than 5,000 years of wine-making.
“I’d love to do it,” she said. “I will continue to strengthen the culture of the two countries and hope that the two countries will become better and better.”

3 . The Amazon Rainforest, often called the “lungs of the Earth”, has always mesmerized me with its biodiversity (生物多样性) and local tribes (部落). When I had the chance to join a research expedition, I took it, excited about the adventure ahead. I didn’t know it would be a great experience.
The journey into the rainforest was tough, such as the dense leaves, endless rain and the sound of insects and animals. However, the beauty of the rainforest was amazing.
One of the most exciting parts of the trip was meeting a local tribe. Their way of life, so connected to nature, was different from our urban lives. Learning about their customs and understanding their relationship with the rainforest was a special experience. It made me realize how separated from nature we have become in the technological advancement.
The trip was not without challenges. Walking in the forest, dealing with the bad weather and dealing with the fear of the unknown tested our willpower. However, every challenge we overcame brought a sense of achievement and strengthened our team bond. It taught me the importance of teamwork and adaptability.
As we left the rainforest, I recalled the impact the trip had on me. It was not just an adventure but a journey of self-discovery.
My trip to the Amazon rainforest was a meaningful experience. It was a journey that pushed my boundaries(边界) taught me valuable lessons and left me with unforgettable memories. It was not just a trip, but an exploration of the unknown and a reminder of our responsibility towards our planet. The adventure may have ended, but the journey continues, as I carry the lessons and memories with me, influencing my life and choices.

4 . Favored by many internet influencers, the city of Zibo, once a sleepy industrial city, has gone viral on Chinese social media platforms. The topic Zibo “barbecue” on Douyin, the Chinese version of TikTok, was played 4.96 billion times since the city stormed the Internet for over a month. On 29 April, Zibo Railway Station saw a record 87,000 train trips to and from the station, according to Chinese news website Caixin.
Local authorities in Zibo have been quick to respond to the sudden flow of visitors. A barbecue zone that can accommodate 10,000 people, featuring live band performances, was built overnight. Volunteers have been dispatched to the railway station to offer advice and recommendations to tourists. Designated (指定的) buses and trains bring tourists to and from the hottest barbecue spots. The government has even threatened to punish profiteering hotels who raise prices by more than 50% .
What makes Zibo barbecue so special is that it does offer a distinctive (独特的) dining experience. The skewers (烤串) are 70-80 percent cooked before they are brought to the table, where diners can finish cooking them on their own stoves, offering an immersive dining experience.
Zibo’s low prices are also appealing. Many college students in Shandong have made concrete plans to enjoy Zibo barbecue at the least cost, and traveling back and forth by train for only 200 yuan ($29.1). So what better way to attract adventurous, hungry college students with a tight budget other than “tasty barbecue that makes you full for only 50 yuan!”
The locals seem happy enough about the arrival of visitors and shy away from hot spots to make space for outsiders, saying they are proud that their hometown has gained nationwide fame.

6 . As you read this, pause to reflect on your recent interactions. As a politician, husband, and father, I encounter various spoken language styles: analytical or chatty, formal or informal, pointed or gentle, cooperative or decisive. Talk is the currency of politics. It is our way of negotiating, debating, and persuading. Talk is also the currency of learning-how we develop our ideas, deepen our thinking and share our feelings.
That’s why I want speaking skills, sometimes called “oracy”, to play an important part in Labor’s plans for a reformed school curriculum (课程).
Employers value speaking skills equally with reading and writing. The ability to speak well and express yourself should be something every child should master. But the curriculum doesn’t allow us to provide this. This is short-sighted. An inability to express your thoughts fluently is a key barrier to getting on and doing well in life.
Oracy is in part about good public speaking and debating skills, but in reality, it’s about teaching young people to make strong arguments, choose wise words, understand their audience, form meaningful social connections, and use facial expressions and body language to convey their message. Above all else it’s about finding your voice. To work out who you are and what you believe. If reading opens up a world of imagination and possibility, then speaking and listening opens up a lifetime of empowerment-a chance for those who feel invisible in their own country to be heard. It is about the confidence to speak out, to call out injustice or harm.
And the other side of speaking is listening, which can also be taught. Listening, truly listening, develops tolerance and understanding. And as parents we can play our part. We’ve all been there, at mealtimes, silent as we all stare at our devices. Our job, all of ours, is to get off our screens and give young people, and adults, the gift of listening.
So, oracy―speaking and listening―needs to be placed firmly at the heart of school life.

7 . Is It Worth Buying Organic Food?
Organic food, grown without artificial chemicals, is increasingly popular nowadays. Consumers have been willing to pay up to twice as much for goods with organic labels (标签). However, if you think paying a little more for organic food gets you a more nutritious (有营养的) and safer product, you might want to save your money. A study led by researchers at Stanford University says that organic products aren’t necessarily more nutritious, and they’re no less likely to suffer from disease-causing bacteria, either.
The latest results, published in the Annuals of Internal Medicine, suggest that buyers may be wasting their money. “We did not find strong evidence that organic food is more nutritious or healthier,” says Dr. Crystal Smith-Spangler from Stanford. “So consumers shouldn’t assume that one type of food has a lower risk or is safer.”
For their new study, Smith-Spangler and her colleagues conducted a review of two categories of research, including 17 studies that compared health outcomes between consumers of organic against traditional food products, and 223 studies that analyzed the nutritional content of the foods, including key vitamins, minerals and fats.
While the researchers found little difference in nutritional content, they did find that organic fruit and vegetables were 20% less likely to have chemicals remaining on the surfaces. Neither organic nor traditional foods showed levels of chemicals high enough to go beyond food safety standards. And both organic and traditional meats, such as chicken and pork, were equally likely to be harmed by bacteria at very low rates. The researchers did find that organic milk and chicken contained higher levels of omega-3 fatty acids, a healthy fat also found in fish that can reduce the risk of heart disease. However, these nutritional differences were too small, and the researchers were unwilling to make much of them until further studies confirm the trends.
Organic food is produced with fewer chemicals and more natural-growing practices, but that doesn’t always translate into a more nutritious or healthier product. The U.S. Department of Agriculture (USDA) states that “Whether you buy organic or not, finding the freshest foods available may have the biggest effect on taste.” Fresh food is at least as good as anything marketed as organic.

8 . Many Silicon Valley parents are becoming more concerned about preventing their children from using screens. Some parents think that even a little screen time can be extremely addictive, so it is better if their children avoid using or seeing these devices completely. However, it is difficult for working adults in the 21st century to give up using a phone at home. So, it’s simpler to employ someone to do this.
“Silicon Valley nanny (保姆)”, who takes children back to a time without screens every day is widely needed. From Cupertino to San Francisco, it’s widely agreed that screen time is harmful to youngsters. Therefore, parents are requesting nannies to keep phones, tablets and computers in a hidden place. Others even offer no-phone agreements.
Research shows that spending too much time on technology can harm young minds. For example, teenagers who use social media frequently are more likely to feel depressed and anxious. Insomnia (失眠) rates have also increased amongst this age group, and an increasing number of children display the signs that they can’t focus attention. These seemingly minor (轻微的) problems could become significant challenges for future generations.
“Many parents come back home and focus on their smartphones, ignoring whatever their children are trying to say,” said Shannon Zimmerman, who works as a nanny in San Jose for families that forbid screen time. “As a nanny, I also call on more parents to spend more time with their kids.”
1. Why are the Silicon Valley nannies greatly needed according to the text?| A．To help parents and children balance work and life. |
| B．To teach children how to use technology responsibly. |
| C．To keep children away from screens. |
| D．To encourage children to exercise. |
| A．Feeling confused. | B．Feeling anxious. | C．Feeling bored. | D．Feeling nervous. |
| A．Encourage their children more. | B．Play games with their children. |
| C．Stop using smartphones at home. | D．Spend more time with their children. |
| A．Parents concern about screen time for children. | B．Children are addicted to screen time. |
| C．All parents limit children to phones. | D．Science has no effects on young minds. |
9 . Aron Ralston was a pretty normal guy, but he always had an extremely adventurous desire to travel and see the world. During his childhood, his family moved to Denver, Colorado, a place offering many opportunities to climb mountains, explore, and eventually become the adventurer he’d always wanted to be. Back in 2003, Ralston was climbing in the remote, mountainous area of Southwestern Utah, when the unthinkable happened: Aron got stuck in a crevice (裂缝) in the rocks and pinned by a big stone that weighed over 360 kilograms. The weight of the rock crushed his arm, and he was pinned by it. Aron took photos of his bad situation (which was going to get a lot worse), hoping rescue teams (救援队) would know where he was and came to remove the rock so that he could get out and home safe.
But rescuers never came. Aron waited for them for days till he lost his hope. He knew he had to do something. He was 18 meters above the floor of the valley where he was pinned in, and he had a pocketknife. He made what must have been one of the most difficult decisions of his life: to cut his own arm in order to survive. Aron cut the lower part of his arm off, having to wrench (扭动) his forearm against the big stone to break the bones, and then got himself down to the bottom of the valley, where he would begin to walk and search for help. Luckily, help arrived in the form of a helicopter (直升机) that spotted him, covered in blood. Aron had tied off the wound to keep himself from bleeding to death pretty successfully and would eventually make it out alive.
Ralston went on to become an inspiring speaker and continued to travel and climb mountains—he didn’t let an incident that forced him to cut his own arm off, stop him from doing what he really loved.

10 . People tend to use trees for papermaking. But maybe electronics (电子) engineers are missing out on something here. “It turns out that two major building blocks of wood have a lot of electrical qualities,” says Magnus Berggren, a professor at Linköping University.
His team has been working to make parts for electronics from the forest. Right now, they’re focusing on two materials of trees. The first material is cellulose, which can make energy. Lignin, the second material, can store that energy, just as a battery does. The team has found when pressed, cellulose can produce electricity.
Some device must then store the electricity until it’s needed. Batteries can do this. But batteries aren’t very green. They have harmful materials. That’s where lignin comes in.
Batteries cause electrons to flow from one place to another, which can produce electricity. In a typical battery, one material must give electrons. The other must accept them. Lignin can do both. A weak acid (酸) encourages lignin to produce electrons. “With a metal wire (金属线) to guide those electrons, you’ll have electricity,” says Berggren.
Berggren’s team use this quality to create its new lignin-based battery. Typical batteries use a metal wire as a path to guide the flow of electrons into or out of the device. But since Berggren wants to make a battery of the forest, he looks for a natural way. Once again, he turns to cellulose.
This natural material can serve as a wire-like path for electrons. To make it work well, Berggren lines them with another chemical known as PEDOT, which isn’t from a tree. But when PEDOT is added to cellulose, they can conduct electricity like a wire. “With a weak acid, now you have a battery,” Berggren says. “And two of its three materials come from the forest.”
Berggren can imagine one day having mobile phone batteries made largely from forest products. Tree-based electronics might also be useful in lighting.
