3、My brother Bon was five-year older than me. He passed away1 at the age of seventy-one. My earliest memory of him was when he2 my injured finger with tapes, a gesture that3 his lifelong care for me.
Following his sudden passing, I had a scheduled massage (按摩) for self-care, which I knew I needed more than ever. I described my4 to the massage therapist (治疗专家) as feeling like a piece of a puzzle had been5 from my life. Her gentle touch and reassurances were a source of comfort.
The next day she6 me into her office and said that she had a story to tell. After the massage, she felt my7 and wondered where she could find a tiny puzzle piece to8 me that my brother's love would never fade. On a cold, windy evening, she9 a friend's house for warmth and discovered her friend had completed a large,10 puzzle. Among the numerous pieces was a small,11 one.
Her friend had no use for the unfitted piece, but my therapist knew it was12 for me. She believed it to be a final13 from Bon, a symbol of his lasting14 in my life. Now, that puzzle piece resides in the pocket of my coat, serving as a constant reminder of my brother's love, providing me with the warmth and15 that his love is always with me.

4、Do you ever feel as though your parents fail to truly listen to you? When you talk to them, they may give the impression that they're taking in what you say. This is one challenge you encounter.
As you grow up, you're becoming more independent and have more questions and opinions. You might start questioning whether your parents truly understand what they're discussing, which can lead to conflicts. It's crucial to respect your parents and grasp why they might hold different opinions. However, they also need to understand your perspective and allow you to make your own decisions. After all, in only a few years you'll probably leave home and have to look after yourself!
Although this situation is common, it remains difficult. Your home should be a place where you can talk openly. Remember, parents are human and can be hurt by your words. Try to remember that in every family there are good times and bad times, but your parents are there for you throughout. Show your appreciation for this, and they'll see you're not trying to cause trouble.
Be sensitive! If you need to talk, don't do it before your parents go to work or bed. Consider your words carefully, keep calm and be open and honest. Don't compare them to your friends' parents. Understanding that many other tens face the same issue helps best in handling your feelings.
Remember, there's no reason why people should automatically understand all your views. The more you engage in conversations with your parents, the better you'll feel. If you find it difficult to speak with them, seek out another family member, teacher, or the one who can offer support. Stay optimistic, and remember that soon you'll be making your own choice.
A. It won't help and could make things worse.
B. In fact they're often not actually doing so at all.
C. Obviously, it's important to respect your parents.
D. keep talking and don't take yourself too seriously.
E. But that doesn't mean they're right on this occasion.
F. Then you'll beam their trust, and they might become more tolerant.
G. Their priority is to provide you with a secure and structured environment.

5、Scientists have long been amazed at the large size of the human brain, which is seven times larger than expected for animals of our size. A significant part of our extra neutrons (神经元) is located in the frontal cortex (额叶皮层), the region responsible for complex thought. To understand this, researchers have studied primates (灵长类), which also have large brains. Primates with larger frontal cortices tend to live in larger groups, suggesting that social complexity may drive brain evolution.
The social brain hypothesis (假说) proposes that the frontal cortex expanded in our ancestors due to the benefits of social intelligence. Brain imaging studies show that thinking about others activate the frontal cortex, supporting this idea. However, most research has focused on primates, with many scientists believing their social complexity is unique.
Dr. kays Holekamp, a professor at Michigan State University, challenge this view. Studying spotted hyenas (鬣狗), she found they live in societies as complex as macaque monkeys, with groups of 60-80 individuals who recognize each other. Hyenas exhibit strict social ran kings, with dominant female controlling access to food.
From a CT-scan of a hyena skull, it is possible to reconstruct the 3D structure of the brain it held. Dr. Holekamp and her colleague have been working to survey dozens of skulls from all four species in the hyena family. They suggested that species of hyenas with more complex social systems have larger frontal cortices. This finding supports the social complexity hypothesis and broadens our understanding of the evolution of social intelligence.
"It's just what the social complexity hypothesis would predict," Dr. Holekamp said. "The hyenas with the simplest social systems have the tiniest frontal cortices. The spotted hyena, which lives in the most complex societies, has far and away the largest frontal cortex."
Joan Silk, a private expert, noticed Dr. Holekamp's work, saying, "Her studies bridge primates and hyenas, revealing shared rules in social complexity and brain evolution."
(1)、Which theories about the evolution of the human brain is presented?A、Frontal cortex growth is limited by skull structure. B、Human brain evolved due to increased physical activity. C、Human frontal cortex increased in size for social intelligence. D、Frontal cortex expansion is driven by social ran kings.(2)、What did Dr. Holekamp's team find after analyzing hyena skulls?A、Hyenas follow the same brain-size evolution pattern. B、Hyenas' frontal cortex size is reconstructed by CT-scan. C、Hyenas with larger bodies tend to have larger frontal cortex. D、Hyena brain structure changed from simple to complex.(3)、What is the significance of Dr. Holekamp' work according to loan Silk?A、It proved that hyenas are more intelligent than primates. B、It showed the interconnectedness of species' social systems. C、It demonstrated the limitations of current research methods. D、It completely overturned previous research on brain evolution.(4)、What is the purpose of the passage?A、To contrast hyena and human brain structure. B、To highlight hyena family species' evolutionary histories. C、To argue that hyena studies reveal more of brain function. D、To discuss what hyena studies show about social intelligence. -
6、Growing up, my older brother, a science enthusiast, shared fascinating facts with me, like how our cells are completely new every seven years. This idea highlighted the concept of constant change in our selves, meaning I'm a physically different person from the one I was years ago.
Today, I often wonder: Am I a story that's constantly being written? people have debated this for a long time, with ancient Greeks arguing whether a thing's true essence lies in its unchanging nature or its ongoing development.
Plato believed that natural science focuses on the changing physical world, while philosophy, using intelligence and reason, explored the change less eternal (永恒). For instance, veterinary science studies growing dogs, but philosophers question the idea of "Dog" itself.
Aristotle agreed that science explains what we see but argued that the material universe is in constant change. He believed change is part of the true nature of things and your virtue is about who you're turning into, not a fixed identity. As such, becoming was his focus, rather than some perfect invisible being.
So, which is your view, and how does that guide the way you live? None of this is to say the choice between Platonism and Aristotelianism is absolute. We all have some unchanging characteristics, and we also change in many ways. The philosophical perspective you adopt will depend on how you principally define yourself and what you choose to pay attention to as you move through the world.
Are you more like a Platonist or an Aristotelian? It depends on whether you see yourself as having a fixed identity or a changing story. Today's culture often pushes you to be a Platonist, defining yourself as a certain type of person. This can make you a repeat customer and give you a sense of belonging. But it might also keep you in situations you don't like. Being more like an Aristotelian can set you free.
(1)、What did the author tell us about our cells in Paragraph 1?A、The unchanging nature of our souls. B、The ongoing transformation of our bodies. C、The belief that our science and nature do not change. D、The idea that we are the same person through our lives.(2)、According to Aristotle, what is the focus of understanding a dog?A、Its unchanging nature. B、Its determined essence. C、Its stable identity. D、Its continuous development.(3)、How does modem culture tend to influence personal identity, according to the text?A、By pushing people to de fin c themselves into fix cd identities. B、By suggesting that personal identity will be a mystery forever. C、By encouraging individuals to accept constant change and growth. D、By promoting that individual identity is deter min cd by belongings.(4)、Which of the following could be the most suitable title for the passage?A、Plate v. s. Aristotle: the Battle of Ideas. B、The Philosophical Outlook: A Defined Personality. C、Becoming v. s. Being: Viewpoint on Personal Identity. D、The Unchanging Universe: A Philosophical Dilemma. -
7、Even when lug was busy, he always welcomed me and let me explore his back room. Lug owned a small, respected piano shop in the city and loved pianos. When it was quieter, he enjoyed my company and told me about the newly arrived pianos. He believed every piano was unique, even if they were from the same maker. Sometimes he knew all about the pianos and their owners.
Other times, he only knew what he could see or hear. Most pianos came from charity sales, with unknown histories. But like an expert, he could tell if a piano was played a lot, kept in the right environment, or had children around it. He could even guess if it was recently shipped. He acted like a detective. His attitude toward pianos mirrored his philosophy of life. While regretting the damage caused by children on keyboard and strings, he found it tolerable because the piano was used and "at the heart of the family." He thought pianos were more than just furniture and that accidental drinking drops were a small price to pay for introducing young people to a joy that comes from comfort, not awe.
I started playing the violin at six, and now I'm seventy-six. It's been a big part of my life. It can't talk, but the instrument can respond with an astonishing range of substance and emotion. This is a special kind of relationship. There are other moments, however, when the violin stubbornly refuses to do as I want— when it only unwillingly plays in tune, or makes the sound I want, or delivers the music's essence for which I pursue. Then I have to persuade, negotiate, or adjust to its every desire.
Luc's ideas connected with me. Luc's ideas connected with me deeply, reminding me that the relationship between musician and instrument is not just about control, but about respect and understanding. In the end, it's the passion and love we pour into our instruments that truly bring music to life.
(1)、How does lug view pianos in his shop?A、As priceless antique to be preserved. B、As instruments that need love and use. C、As objects that should never be touched. D、As commercial products with valuable history.(2)、Which of the following would best describe Luc's philosophy of life?A、Cherish and protect life all the time. B、Always live with devotions and practice. C、Don't take life's opportunities for granted. D、Live with imperfections instead of doing nothing.(3)、What is the author's attitude towards his violin?A、Encouraging and patient. B、Controlling but cherishing. C、Affectionate but demanding. D、respectful and connected.(4)、What is the main idea of the passage?A、It highlights the ben c fits of playing instruments. B、It discusses the role instruments play in daily life. C、It compared the valued of instruments to life understandings. D、It explored the relationship between humans and instruments. -

9、Stars are born in special areas of space called stellar nurseries (恒星孕育区) , where large amounts of gas and dust come together to form new stars. These enormous regions, also known as molecular (分子的) clouds, stretch across hundreds of light-years and create thousands of stars. While scientists have learned a lot about how stars live and die, some details about their birth remain unclear. For example, did stars always form in the same way throughout the universe's history?
A recent study from Kyushu University and Osaka Metropolitan University suggests that stars in the early universe might have formed in soft molecular clouds, which make them float like cotton. This discovery was made by observing the Small Magellanic Cloud (SMC), a small galaxy near the Milky Way. The SMC has fewer heavy elements compared to our galaxy, making it similar to the conditions of the early universe about 10 billion years ago.
In our galaxy, molecular clouds that help form stars usually have a long thin shape. Scientists think the solar system was created in a similar way, where a large molecular cloud broke apart to form a core that eventually became a star. Over time, gravity pulled more gas and matter into these cores, leading to star formation.
Kazuki Tokuda, a researcher at Kyushu University, explains that understanding how stars formed in the early universe is challenging because the universe was mostly made of hydrogen and helium (氦) back then. To study this, the team used the ALMA radio telescope in Chile to observe the SMC. They found that 60% of the molecular clouds had the usual long thin shape, while 40% were soft. The temperature inside the thin clouds was higher than that in the soft ones, which might be due to how old the clouds are.
If a molecule cloud keeps its long shape, it's more likely to break apart and form many stars like the sun. However, if it becomes soft, it may be harder for stars to form. This study shows that having enough heavy elements is important for maintaining the long shape of molecular clouds, which can be crucial for forming planetary systems.
(1)、How does the author introduce the text?A、By listing scientific data. B、By describing a natural process. C、By raising multiple questions. D、By comparing molecules.(2)、What is the study mainly about?A、The SMC's composition. B、The substances of the universe. C、The properties of soft molecular clouds. D、The star formation in the early universe.(3)、What could possibly be related to the temperature difference in molecular clouds?A、Their size. B、Their height. C、Their shape. D、Their age.(4)、What does the last paragraph mainly tell us?A、The conditions for stars to form. B、The use of elements in soft clouds. C、The structures of molecular clouds. D、The complexity of planetary systems. -
10、阅读下面材料,根据其内容和所给段落开头语续写两段,使之构成一篇完整的短文。
As I was driving home from work one night last week, the light on my dashboard was flashing on the "dreaded" tire pressure maintenance system. My heart sank. It usually means one of two things: low tire pressure or tire sensor failure. The temperature outside dropped below freezing, and the icy wind blew through my coat as I pulled into the driveway. I hoped it was just a tire pressure problem that could be easily solved with a quick pump. But deep down, I knew it could be more complicated.
The next morning, I drove to the tire shop as soon as it opened. The mechanic on duty greeted me with a friendly smile but informed me that they were fully booked with appointments. My car was pushed to the bottom of the list. I glanced at the clock. It was going to be a long wait. I decided to make the best of the situation and get some exercise. I walked home, the cold winter air filling my lungs as I enjoyed the quiet streets.
Hours later, I returned to the tire shop. The mechanic confirmed my fears: It was indeed a faulty tire sensor. The repair took longer than expected, but the staff worked diligently, their professionalism evident in every move. When the job was finally done, I felt a wave of gratitude. These mechanics had been incredibly accommodating; even without an appointment. I decided to show my appreciation.
On my way back, I stopped at a nearby store. I purchased two large bags of chocolates, my go-to thank-you gift. One bag was for the tire shop staff. They deserved it. The other bag was for the library staff, my next destination. I'm a regular at the library, always knowing exactly which books I want to read. I rarely look through the shelves; instead, I reserve my books online and wait for the notification. When I pick them up, I always thank the staff, but sometimes, a simple "thank you" isn't enough. A chocolate treat, on the other hand, always brings a smile to their faces.

1.续写词数应为150个左右;2.请按如下格式在答题卡的相应位置作答。
As I entered the library, the familiar smell of old books and fresh coffee greeted me.

12、阅读下面短文,在空白处填入1个适当的单词或括号内单词的正确形式。
More than 80 archaeological sites and artifact distribution points containing artifacts that date back from the Neolithic Period (新石器时代) modern times have recently been discovered in South China's Guangxi Zhuang Autonomous Region.
This cluster (集群) of considerable size was discovered along the coast of Beibu Gulf in Guangxi. The area has long been known as a cradle for underwater discoveries as well as findings shed light on cross-cultural and cross-ethnic exchanges.
Pottery pieces with comb-patterned designs (find) among some of the cluster's ruins such as the Shanmiaoling site and the Dishuiping site. Other excavated sites such as Wayaodong, Masiling and Duimianling are characterized by Warring States Period and Qin Dynasty archaeological features. The artifacts (collect) on the spot are mainly pottery wares decorated with patterns similar to the Chinese character "米", or featuring grid motifs and waffle pattern designs. These findings provide significant (refer) for studying the Qin and Han's handicrafts developments.
The cluster's sites not only belong to a (various) of different time periods, but they are also quite diverse, including city ruins, settlement sites, tombs, and (remain) that are identified as iron-smelting locations.
The (new) discovered archaeological cluster resulted from a survey (focus) on Beibu Gulf archaeology, conducted by the Guangxi Institute of Cultural Relics Protection and Archaeology in 2024. The survey lasted nearly 70 days and covered area of 20,000 square kilometers.

As they2, she learned about his past as a hard-working trucker, his deep love for dogs and plants, and the3 hardships he had endured. Chronic (慢性的) health problems had made it difficult for him to hold a4, and he had been living on the streets for far too long.
Moved by Don's situation, Watson5 wanted to help. She first thought of6 him at the café, but his poor health made that7 impractical. So she chose to pay for a short stay at a nearby motel to give Don a warm place to8. Then, she took to social media, sharing Don's9 and calling on the community for support.
The10 was nothing short of amazing. People from all over the town stepped forward. Someone11 a warm hunting winter coat, along with hats, gloves, scarves, and masks. A kind-hearted local offered Don an apartment at a mere $50 a month, and another individual12 to pay the rent for the rest of the year.
Don was incredibly13. All he ever asked for were simple things like instant coffee. This heart-warming story shows that a single act of14 can have a far-reaching impact.

14、Bad thoughts can be a persistent, invisible weight that you carry from day to day. Fortunately, there are strategies you can use to block out or at least minimize negative thinking so that it doesn't bother you.
Remember that you're not a bad person for having bad thoughts. Everyone has negative thoughts. As you experience life and emotions, various thoughts — good and bad — will pass through your mind. These random intrusions (侵入) are just thoughts, not real-life actions or reflections of your moral integrity.
Release negative thoughts and images with mindfulness. Instead of focusing on your negative thoughts or images, try viewing them as a passive observer. Then envision yourself letting them go like physical objects and watching them float away and out of your mind.
The media we consume has a significant impact on our mental health, especially the younger we are. If you read news or books, watch movies or TV shows, or play a lot of video games that contain elements of violence, horror, or other topics that leave you feeling down, limit your consumption of these materials.
Speak to yourself in the way you'd speak to a friend. When an especially harsh, negative thought about your self-worth or appearance worms into your mind, take a step back and examine the thought critically. So you shouldn't speak to yourself that way, either.
Practice gratitude each day. Using your phone or a physical notebook, record a few things you're thankful for. These can be as simple as sunny weather or a kind driver letting you turn onto a busy road. When you cultivate gratitude, you give negativity less room to thrive in your headspace.
A. That's just how the human brain functions.
B. Think about the activities that make you happiest.
C. You wouldn't speak in that critical tone to a friend.
D. Limit or avoid media that disturbs, frightens, or depresses you.
E. They may make fun of you, but remember that you know your mind best.
F. Try to practice gratitude around the same time each day so it becomes a habit.
G. Focus on the present, allowing your thoughts to wander in and out of your mind.

15、A new study from the University of Texas at Arlington (UTA) has found that tiny plastic pollutants floating in the air are settling in the lungs of birds. Researchers around the world are increasingly concerned that these harmful particles (微粒) are ubiquitous in the air we breathe and the food we eat.
Shane DuBay, an assistant professor of biology at UTA and co-author of the study, said birds were chosen for the study because they are found in almost every corner of the world and often share environments with humans.
"Birds serve as important indicators of environmental conditions," said DuBay, who collaborated with researchers from Sichuan University and Chengdu Tianfu International Airport, both in Chengdu, China. "They help us understand the state of the environment and make informed decisions about conservation and pollution control."
DuBay's team studied 56 different wild birds from 51 distinct species, all sampled from the Chengdu Tianfu International Airport in western China. They collected lung samples from each bird and performed two types of chemical analyses.
They used laser direct infrared technology to detect and count microplastics in the birds' lungs. The study found high concentrations of microplastics in bird lungs, with an average of 221 particles per species and 416 particles per gram of lung tissue. The most common types identified were chlorinated polyethylene, used for insulating pipes and wires, and butadiene rubber, a synthetic material in tires.
While no official "safe" level of plastic particles in lung tissue exists, high levels of microplastics have been linked to serious health conditions, including heart disease, cancer, breathing problems and fertility issues.
"Our research highlights an urgent need to address plastic pollution in our environments, as these pollutants can have far-reaching impacts on ecosystem health, as well as human health," DuBay said. "Our findings call for further research, funding and action to reduce the harmful effects of plastic pollution and ensure a healthier environment."
(1)、What does the underlined word "ubiquitous" in paragraph 1 mean?A、Widespread. B、Invisible. C、Dangerous. D、Obvious.(2)、Why were birds chosen for the research?A、They help identify microplastics. B、They reflect environmental health. C、They indicate urban pollution levels. D、They show direct human health impacts.(3)、What is the top priority now according to the researchers?A、To address climate change. B、To promote bird conservation. C、To deal with plastic pollution. D、To study the effects of microplastics.(4)、What can be a suitable title for the text?A、Birds are in danger — and researchers are alarmed B、Birds breathe in dangerous plastics — and so do we C、Birds indicate environmental health — and research is ongoing D、Birds share environments with humans — and pollution is everywhere -
16、Novel technology intends to redefine the virtual reality (VR) experience by expanding to incorporate a new sensory connection: taste. The interface, named "e-Taste", uses a combination of sensors and wireless chemical dispensers (分配器) to facilitate the remote perception (感知) of taste — what scientists call gustation.
These sensors can identify molecules (分子) like glucose and glutamate — chemicals that represent the five basic tastes of sweet, sour, salty, bitter, and umami. Once captured via an electrical signal, that data is wirelessly passed to a remote device for copying.
Field testing done by researchers at the Ohio State University confirmed the device's ability to digitally simulate (模拟) a range of taste intensities, while still offering variety and safety for the user.
Taste is a subjective sense that can change from one moment to another. Yet this complex feeling is the product of two of the body's chemical sensing systems working at the same to ensure what you eat is safe and nutritious, the taste and the smell senses. "Taste and smell are greatly related to human emotion and memory," said Jinghua Li, co-author of the study and an assistant professor of Materials Science and Engineering at the Ohio State University. "So our sensor has to learn to capture, control and store all that information."
Despite the difficulty involved in exactly simulating similar taste sensations for a majority of people, researchers found that in human trials, participants could distinguish between different sour intensities in the liquids generated by the system with an accuracy rate of about 70%.
Further tests assessing e-Taste's ability to immerse players in a virtual food experience also analyzed its long-range capabilities, showing that remote tasting could be initiated in Ohio from as far away as California.

17、As the founder of UK nonprofit The Esther Project, Lianne Kirkman, who works to provide shelter, recovery, and rehabilitation (康复) to women experiencing homelessness, has been at the forefront of her career for over a decade. But this year, in an effort to truly learn more about the lived experiences of the people her organization serves, Kirkman set off on a 10-stop tour across the country, meeting with other shelters and nonprofits — and sleeping on the street for 10 nights in a row.
Along her stops, Kirkman met with other nonprofits working to specifically support women facing homelessness. She started at her home base of Royal Leamington Spa on February 1 of this year and then traveled to Coventry, Birmingham, Bristol, Plymouth, Southampton, London, Doncaster, Hull, and Blackpool. She finally arrived back home earlier this week.
"I am so grateful for the fact that I can go home," she said. "It's been awful every morning thinking I can't go home and that I can't get in a bed. This has been one experience I will never, ever forget."
Women experiencing homelessness face unique barriers that often go overlooked. According to The Esther Project, 65% of Londoners in temporary accommodation are women. But many do not feel safe with those accommodations and those who cannot access them also face the dangers of street-sleeping, as well, leaving them with nowhere to go.
Kirkman's journey was meant to truly understand these realities. In addition to raising awareness, the 10-night sleepout has raised over £14,000 (about $17,400) for The Esther Project. It will go towards opening a new "one stop shop women's center" in Warwickshire.
Kirkman said she originally thought she'd raise £5,000, but the support on her journey was greater than expected.
"We are really amazed by the support we're getting," she said. "This was mainly a research project for me. This was about working out best practices for women, and I've been amazed by some of the fantastic organizations I've been to. You've taught me a lot," Kirkman continued. "I know what we need to do."
(1)、Why did Kirkman sleep on the street for 10 nights?A、To compete with other shelters in fundraising. B、To test her survival skills in extreme conditions. C、To promote her nonprofit organization publicly. D、To experience homeless women's lives in person.(2)、How did Kirkman feel after finishing her street-sleeping experience?A、Regretful. B、Relieved. C、Thrilled. D、Annoyed.(3)、What issue do homeless women in temporary shelters face?A、Safety concerns. B、Strict shelter regulations. C、Limited medical resources. D、High accommodation costs.(4)、What is the main use of the money raised?A、Providing direct financial aid. B、Expanding shelters nationwide. C、Creating a women's support center. D、Funding homelessness research. -

19、阅读下面的材料,根据其内容和所给段落开头语续写两段,使之构成一篇完整的短文。
Last year at Christmas time, my wife, three children and I were on our way from Paris to Nice.Somehow everything went wrong. Our hotels were "tourist traps" and our rented car broke down. On Christmas Eve, when we checked into a dirty hotel in Nice, there was no Christmas spirit in our hearts.
It was raining and cold when we went out to eat.We found a small restaurant poorly decorated for the holiday.Only five tables in the restaurant were taken.There were two German couples, two French families, and an American sailor, by himself. They were eating in stony silence except the sailor.He was writing a letter, and a halfsmile lighted his face. In the corner a piano player was listlessly (无精打采地) playing Christmas music.
All of us were interrupted by an old French flower woman through the front door. She had a worn overcoat and her old shoes were wet.Carrying her basket of flowers, she went from one table to another. No one bought any. Exhausted and frustrated, she sat down at a table.
The sailor finished his meal and got up to leave. Putting on his coat, he walked over to the flower woman's table.
"Merry Christmas, " he said, smiling and picking out a handful of flowers."How much are they?"
"Two francs, Sir."
The sailor put a twenty franc note in the woman's hand.
"I don't have change, Sir, " she said. "I'll get some from the waiter."
"No, ma'am, " said the sailor, leaning over and kissing the ancient cheek."This is my Christmas present for you."
注意:1.续写词数应为150左右;
2.请按如下格式作答。
Then the sailor headed for our table with the flowers in his hand.
