But when your world has become smaller since the pandemic (疫情) hit two-and-a-bit years ago, but it slowly1, the most ordinary experience gives new2 to life. And so it was with me when I was finally given the chance to take my first3 in more than two years.

    I'd forgotten how it felt to be among the people coming and going. I got to the airport two hours before boarding. Plenty of time for the bar and, of course,4.

    That group of young Arab women laughing and posing for photographs by the expansive windows, aircraft in the5, lighting up the place with their happiness.

    The man in the corner drinking alone. Just another common one of the 70,000 or so stories that would pass through the airport6.

    I couldn't be calmer as a flyer. But when the plane took off I was7, in that moment of weightlessness as the wheels8 Earth, leaning towards the window to watch everything below becoming smaller and smaller.

    Is it possible that the denial of so much during the pandemic lockdown had added new9 to what was the ordinary? I think so. The plane ride, the hotel stay, and the social occasion all now gave me a sense of10 that might have previously only aroused in me nothing more than a certain nonchalance (若无其事) or even11.

    Last June, just ahead of the long Sydney lockdown (管控), a friend12 a birthday party. That experience for me would continue happily through some of the13 months of the lockdown that would follow.14 the repeated fear that the pandemic holds over us, the memory of that celebration still keeps its bright, warm light in my mind. That's what happens when everything old is new again, when15 is rediscovered as a virtue.

  • 7、Tips for Planning a Nature Walk With Your Child

    When it comes to planning a nature walk, the key tip to keep in mind is to have fun with it! If children are given the opportunity to experience nature, even in simple ways, interaction and engagement follow quite naturally.

    Let your children get dirty.

    If your little one is anxious to crawl (爬) in the dirt to get a better look at worms, then go for it! Research suggests that kids who play the dirt are exposed to bacteria, germs and viruses that can help build their immune (免疫) system and reduce the risks of certain allergies and illnesses later in life.

    Encourage them to stop to turn over rocks, touch moss, and when they can, climb on and over rocks and fallen trees. Whatever the environment, which you assess for any unreasonable danger, the children can set the pace — stimulating confidence, flexibility, problem-solving, creativity, and a sense of wonder.

    Get creative.

    Davis suggests pretending play, such as using a stick as a s word or magic wand, or making up stories about the items found during your walk. Your findings also work great for an art project. "Collecting rocks while on your nature walk can later he painted and re-purposed as beautiful works of art," says Davis.

    Let older children be more adventurous.

    For the older kids, it's all shout making a deeper connect ion with the world around them. With older kids, you can encourage them to connect with nature on a deeper level by exploring their senses. .

    A. Assess environment.

    B. Have your children lead the way.

    C. Nature is perfect for a child's creativity.

    D. Nature walks don't have to be complicated.

    E. Dirt might get a bad reputation, but it shouldn't.

    F. Try having them walk barefoot on different surfaces.

    G. Give them the freedom to play in their own ways.

  • 8、In Chinese cities, food deliverymen are often seen riding at full speed through busy traffic. They rushed from restaurants to different destinations, even under bad weather conditions.

    The article The Food Deliverymen Are Trapped in the App pointed out that on food delivery service platforms, Eleme and Meituan, the time limit and the route for each delivery order is calculated by an algorithm(算法).But the algorithm doesn't consider real-life situations, such as red lights, speed limits and fully occupied elevators.

    The time limit for a delivery order within 2 kilometers is 30 minutes, even shorter in recent years. Delay could mean a fine. So deliverymen rev up, often breaking traffic rules, putting their own lives at risk.

    Many people asked the platforms to improve the regulations imposed(强加) on the deliverymen. In response to this demand, Eleme announced it would add a button to the app, which allowed customers to extend the time limits for their orders, and encouraged customers to show more respect for deliverymen. But some people felt that the company was staying away from the problem and changing people's attention. Some held the view that the company was putting the responsibility on the customers rather than solving the problem itself.

    As to delivery delays, solutions are far from enough. As a matter of fact, when a delivery delay happens and the company can' t reach an agreement with the customer on the responsibility, the deliveryman is usually the final one responsible for the delay. The Shanghai Customer Council commented that it was unfair for the deliveryman to be the only side responsible for a delay and problems should be solved between the companies and their employees. Besides, market regulatory departments should stop companies from setting tight schedules for their deliverymen and keep them safe on the roads.

    (1)、What does the underlined expression "rev up" in Paragraph 3 probably mean?
    A、Run away. B、Speed up. C、Wander around. D、Slow down.
    (2)、Who actually gets the blame for a delivery delay?
    A、The Customer Council. B、The customer. C、The company. D、The deliveryman.
    (3)、What did the Shanghai Customer Council advise market regulatory departments to do?
    A、Set tight schedules for more orders. B、Solve the problems of delivery delays with the customers. C、Stop companies from setting tight schedules for their employees. D、Employ more deliverymen for the delivery companies.
    (4)、What's the text mainly about?
    A、The customers' rights should be protected. B、Food delivery regulations need improvement. C、Food deliverymen take risks on their way. D、Delivery platforms earn more than before.
  • 9、"Practice makes perfect" is a very popular expression. However, can we take this saying literally? Many scientific studies have sought to either prove or disprove this idea.

    One popular theory is that if a person practises for at least 10,000 hours, they will reach "perfection", or become an expert in their field. This theory was made famous by Malcolm Gladwell in his 2008 best selling book, Outliers: The Story of Success. He mentioned the music group The Beatles and Microsoft co-creator Bill Gates. Although they all seemed to have lots of natural talent, they also clearly put in over 10,000 hours of practice before they became successful.

    Gladwell's work was largely based on research done by Anders Ericsson, who argued that Gladwell misinterpreted his research. Firstly, Ericsson stated that 10,000 hours was an average figure. Some people needed far fewer than 10,000 hours, and others many more. More importantly, Ericsson said that just practising a lot was not enough; the type and quality of practice was also essential. He went on to explain the importance of "deliberate practice", which is when a person practises a specific part of a skill in depth rather than practising a skill as a whole.

    A more recent study from Princeton University stated that practice only accounted for up to 26% of reaching an expert level. Many people say that natural talent has a large influence on becoming an expert. Another natural factor is physical superiority, which is especially evident in sports. IQ, personality, attitude, and starting age are decisive, too. But becoming an expert doesn't equal instant success, which also relies on social and environmental factors.

    In conclusion, practice may not make perfect, but deliberate practice has been shown to lead to significant improvement. Based on Ericsson's research, here are some tips on how to practise effectively: be motivated; make specific and realistic goals; work outside your comfort zone; be consistent and persistent; and get plenty of rest! For those wanting to become an expert in something, remember that being motivated is key-enjoy what you do and follow your passions.

    (1)、How did Gladwell support his idea?
    A、By listing numbers. B、By using examples. C、By interviewing famous people. D、By mentioning other researchers.
    (2)、Which of the following may Ericsson disagree with?
    A、Practice alone is far from enough. B、10,000 hours of practice leads to success. C、Practice hours vary from person to person. D、Deliberate practice is much more effective.
    (3)、What does paragraph 4 mainly talk about?
    A、The role of practice. B、Factors in creating experts. C、The importance of natural talent. D、Warnings for experts.
    (4)、What is the author's attitude to the idea "Practice makes perfect"?
    A、Favorable. B、Intolerant. C、Doubtful. D、Objective.
  • 10、When a stranger gave Danille and her husband Nathan a box of onions which they later found they didn't need, she decided to pass the kindness on.

    Mindful of many families struggling to feed their loved ones, Danielle placed the onions outside her home with a sign encouraging locals to "take what you need, share what you can". Now, one year on, their stand, called the "Waverley Co-op", provides thousands of locals with 500kg of fruit, vegetables, and bread each week. "Residents and charities donate some produce, and we top this up with $100 of fresh fruit and other foods," says Danielle, who explains that others began adding to the stand with their own donations.

    "A common story we hear is that the items people take from the stand enable them to save a few extra dollars so they can afford to buy meat that week." For a new mum Stacey, it'd been the lifeline she needed to keep food on the table for her family.

    Last year, the 33-year-old's one-year-old son Kaidan ran into a hot fire screen, badly burning his hands and forehead. Then, her husband lost his job. With Kaidan needing urgent medical care in Hobart 200km away, the mother spent four weeks at her son's bedside before returning home, which led to piles of overdue bills at home. "Without the help of the Waverley Co-op, we wouldn't have had food or nappies," says Stacey, who discovered the volunteer-led stand by word of mouth.

    "It has been a blessing to hear the stories and meet the people in our community," says Danielle, who couldn't be happier that a box of onions brought so many people together. "The invisible atmosphere of trust, support, and connection — that's been the biggest success!"

    (1)、How did Danielle deal with the onions?
    A、She let others take them away. B、She donated them to a stand. C、She fed her family on them. D、She exchanged them for fresh fruit.
    (2)、What can we learn about Stacey?
    A、She could merely pay the bills. B、She stayed for a year in Hobart. C、She was jobless after her son's accident. D、She heard about the stand from others.
    (3)、What does the Waverley Co-op finally bring in Danielle's opinion?
    A、Abundant food sources. B、Strengthened bonds among people. C、Moving stories of strangers. D、Increased communication with locals.
    (4)、What is the best title for the text?
    A、A New Mother Saved Her Son B、Danielle Brought Happiness to People C、A Small Stand Made All the Difference D、The Waverley Co-op Gave People Wealth

    With roots (date) back thousands of years, Chinese seals (印章) are more than just unique image; they are symbolic of identity, status, and culture. A Chinese seal is a seal or stamp used to mark important documents, pieces of art, contracts, or any other item that(require) a signature.

    The seal was first created in 221 BC. The first emperor of China, Qin Shi Huang, ordered his first imperial (皇帝的) seal to be carved using beautiful white jade (玉).(call) the "Xi", the imperial seal was only used by those in power. It was in the Ming and Qing dynasties the seal's usage moved from the imperial to the personal, due to the (develop) of arts. Artists began using a stylized seal carving of their names to mark ownership of their works. (individual) also began using a personalized stamp for important documents. These non-official stamps were called "Yin".

    (usual), the seals are carved into stone, but they can also(make) of wood, bamboo, or bone. Seals are carved in one of two ways: the material is carved away from the character, leaving a red ink outline when used on paper, the character is carved into the material, leaving the character in white among a red background.

  • 14、​​​​​​​Last summer, I went hiking with some friends when the sky suddenly darkened and thunder rumbled (发出隆隆声). As we hurried back, my classmate Lily1 on a rock and fell into a shallow stream, hitting her head against a stone. Blood2 seeped (渗出) from her head and she lay there3.

    My mind went4 initially. "Call an ambulance!" someone shouted, but it would take hours for it to arrive. Remembering the basic first-aid course I'd taken, I knelt down, my hands shaking. I pressed5 on her wrist to check her pulse. It was weak but6. I then used my scarf to apply pressure to the wound. Our instructor had emphasized not moving someone with a7 injury.

    Just then, some local farmers, alerted (警觉) by our shouts, appeared with a stretcher. They praised my actions, saying my13 thinking had prevented shock from worsening.

    At that moment, I14 how fragile (脆弱的) life is and how powerful knowledge can be. Sometimes, the most important lessons come not from textbooks, but from15 where we choose to step up. Now, whenever I see a first-aid kit, I remember: preparedness turns panic into hope.

  • 15、​​​​​​​In 1916, two girls of wealthy families, best friends from Auburn, N. Y. — Dorothy Woodruff and Rosamond Underwood — traveled to a settlement in the Rocky Mountains to teach in a one-room schoolhouse. The girls had gone to Smith College. They wore expensive clothes. So for them to move to Elkhead, Colo. to instruct the children whose shoes were held together with string was a surprise. Their stay in Elkhead is the subject of Nothing Daunted: The Unexpected Education of Two Society Girls in the West by Dorothy Wickenden, who is a magazine editor and Dorothy Woodruff's granddaughter.

    Why did they go then? Well, they wanted to do something useful. Soon, however, they realized what they had undertaken.

    They moved in with a local family, the Harrisons, and, like them, had little privacy, rare baths, and a blanket of snow on their quilt when they woke up in the morning. Some mornings, Rosamond and Dorothy would arrive at the schoolhouse to find the children weeping from the cold. In spring, the snow was replaced by mud over ice.

    In Wickenden's book, she expanded on the history of the West and also on feminism, which of course influenced the girls' decision to go to Elkhead. A hair-raising section concerns the building of the railroads, which entailed (牵涉) drilling through the Rockies, often in blinding snowstorms. The book ends with Rosamond and Dorothy's return to Auburn.

    Wickenden is a very good storyteller. The sweep of the land and the stoicism (坚忍) of the people move her to some beautiful writing. Here is a picture of Dorothy Woodruff, on her horse, looking down from a hill top: "When the sun slipped behind the mountains, it shed a rosy glow all around them. Then a full moon rose. The snow was marked only by small animals: foxes, coyotes, mice, and varying hares, which turned white in the winter."

    (1)、Why did Dorothy and Rosamond go to the Rocky Mountains?
    A、To teach in a school. B、To study American history. C、To write a book. D、To do sightseeing.
    (2)、What can we learn about the girls from paragraph 3?
    A、They enjoyed much respect. B、They had a room with a bathtub. C、They lived with the local kids. D、They suffered severe hardships.
    (3)、Which part of Wickenden's writing is hair-raising?
    A、The extreme climate of Auburn. B、The living conditions in Elkhead. C、The railroad building in the Rockies. D、The natural beauty of the West.
    (4)、What is the text?
    A、A news report. B、A book review. C、A children's story. D、A diary entry.
  • 16、When Maya Thompson was 10 years old, she went on a family vacation to the beach and saw hundreds of plastic bottles and bags washed up on the shore. That day, she made a promise to herself that she would do something to protect the oceans.

    Now 22, Maya has kept that promise. She is the founder of Ocean Guardians, a youth-led organization that organizes beach cleanups and educates people about plastic pollution. What started as a small group of friends cleaning up their local beach has grown into a global movement with over 50,000 members in 40 countries.

    One of Ocean Guardians' most successful projects is the "Plastic Free School" program. The organization works with schools to eliminate single-use plastics from cafeterias and classrooms. So far, over 200 schools have joined the program, reducing their plastic waste by an average of 70%.

    Maya's biggest achievement, however, came last year when she led a campaign to ban single-use plastics in her home state. She collected over 100,000 signatures and spoke at the state legislature. After months of debate, the ban was passed, making it the strictest plastic ban in the country.

    Despite her success, Maya remains humble. "I'm just one person," she says. "The real heroes are the thousands of volunteers who show up every weekend to clean up beaches and the students who are changing their schools. Together, we can make a difference."

    Maya's next goal is to expand the Plastic Free School program to 1,000 schools by 2027. She also plans to write a book for children about ocean conservation. "It's important to start educating kids young," she explains. "They are the future of our planet."

    (1)、What inspired Maya Thompson to start protecting the oceans?
    A、A school project about environmental protection. B、Seeing plastic pollution on a beach vacation. C、A documentary about ocean life. D、The encouragement from her parents.
    (2)、What is the "Plastic Free School" program about?
    A、Teaching students about marine biology. B、Organizing beach cleanups for students. C、Removing single-use plastics from schools. D、Raising money for ocean conservation.

    A、Proud and confident. B、Modest and not arrogant. C、Ambitious and determined. D、Kind and generous.

    A、Maya's organization is funded by the government. B、The plastic ban in Maya's state was the first in the country. C、Maya believes collective action is the key to solving environmental problems. D、All schools in Maya's state have joined the Plastic Free School program.

  • 18、​​​​​​​It was hard to say goodbye to the old oak tree in our backyard. She was already1 when my grandparents settled here 60 years ago — gnarled (多节的) but strong, standing tall as a silent guardian over the garden. We have a faded2 of my mother playing under her branches as a child, the tree's leaves3 as if saying hello to her.

    That oak had a unique4. Her trunk (树干) bent slightly to the east, as if reaching for the morning sun, and her branches spread wide enough to cover the entire yard. Kids in the neighborhood loved climbing her thick limbs; birds built nests in her5, and fireflies danced in her leaves at dusk. She was more than a tree — she was part of our family.

    But time took its toll (损失). We watched her6 weaken over the years. The leaves turned yellow earlier each autumn, and some branches dried up and broke off in storms. Even the squirrels (松鼠), who once stored acorns in her bark (树皮), started7. My grandfather sighed, "She's lived a good life, but it's getting8 to have her so close to the house." When a heavy branch crashed onto the fence last winter, we knew we had to call in experts to9 her.

    I couldn't bear the thought of her10 completely. Friends11 me to carve her wood into souvenirs — wooden flutes (长笛), photo frames, or even a small bench. At first, I hesitated, but then I12 their suggestion.

    Now, instead of looking up at her towering form, I can13 pieces of her in my hands. The photo frame holding my mother's childhood picture is14 to the touch, carrying the warmth of the sun she once soaked up. The wooden flute, when played, hums a soft tune (曲调) that feels like a15 of her rustling leaves. The old oak is gone, but her memory lives on — in our hearts and in the things she's become.

    Scientists have long known that having a cheerful personality is good for your health. A positive outlook on life is linked to a healthier heart and longer life. Now, two new studies published this week have found specific healthy behaviors that explain the link.

    Previous research has found that people who are optimistic, have a sense of purpose and are satisfied with their lives have a reduced risk of heart disease and stroke. These healthy habits in turn protect their hearts, according to studies involving nearly 5,000 people.

    One study looked at how a sense of purpose affects our health. Having a reason to get up in the morning, such as work or caring for a loved one, is known to protect against heart attacks and stroke. The new research found that those with a higher sense of purpose were more likely to have lower levels of cortisol (皮质醇) and fewer inflammation (炎症) signs in their blood.

    The second study, of 700 people, showed that optimistic people had significantly lower blood sugar and cholesterol (胆固醇) levels. These are two key risk factors for heart disease. Optimists also tended to be more physically active and less likely to smoke.

    "These studies prove that happiness and life satisfaction influence our physical health," said Dr. Julia Boehm from Harvard University. Happier people have lower risk factors for heart disease.

    But can miserable people learn to be happy? Experts believe yes. Simple techniques like recording good daily events or performing random kindness can boost happiness. So next time you feel down, remember: looking on the bright side could save your life.

    A. Both of them are linked to a higher risk of heart disease.

    B. Being unhappy can increase the levels of stress hormones.

    C. This is probably because they take better care of themselves.

    D. But how happiness protects the heart has long been a mystery.

    E. Optimism is a quality that can be developed, not unchangeable.

    F. They are more likely to eat well, exercise regularly and sleep better.

    G. People with strong purpose seldom suffer from serious heart problems.

  • 20、In the global effort to fight climate change, scientists are exploring solutions in unexpected places — including the soil beneath our feet. A recent study published in Nature highlights a promising discovery: specific bacteria that can dramatically reduce agricultural emissions of nitrous oxide (N2O), a powerful greenhouse gas.

    Nitrous oxide, largely released from farm fields due to nitrogen fertiliser (肥料) use, is a major climate concern. According to co-author Professor Lars Bakken of the Norwegian University of Life Sciences, the gas is 265 times more effective at warming the atmosphere than carbon dioxide and can remain in the air for over a century.

    To develop the solution, researchers grew the bacteria using organic waste. Building on past work, they looked for a microorganism that would reduce nitrous oxide emissions without staying in the soil for so long that it harmed other life forms important for crop health. The bacteria reduced emissions after a second fertiliser treatment by about half two weeks later. After three months, the makeup of microbial (微生物的) life was unchanged, suggesting the bacteria would not harm the soil.

    The bacteria, which are not genetically modified, occur naturally in anaerobic digesters — facilities that transform organic waste into biofuels. That might ease acceptance of their use, said Paul Carini of the University of Arizona, who was not involved in the research. Moreover, Bakken stated that this "opens up a number of new possibilities" for managing farmland. The bacteria could be added to fertilisers, offering a potential direct application for farmers. As Carini noted, using a waste product from one industrial process to benefit another is cost-effective.

    However, significant challenges remain before widespread use. Professor Lori Hoagland of Purdue University, an expert in the field, noted that soils vary globally, requiring more field testing to ensure effectiveness. More critically, farmers currently get no financial motivation to adopt such methods. Bakken argued that authorities must create policies to make emission reductions profitable. If these limitations can be addressed, this bacterial treatment could have a major impact on reducing agriculture's contribution to climate change.
