The ancient practice of stargazing, which (date) back to prehistoric times, has long fascinated humanity. Early civilizations, from the Babylonian astrologers charting constellations to the Polynesian sailors reading the night sky, relied on celestial observations (navigate) vast oceans and track seasonal changes that governed their agricultural cycles. Even today, as cities glow with artificial light, the allure of distant stars continues to draw both amateur sky-watchers and seasoned scientists.

A recent study, (conduct) by a team of astronomers at the University of Edinburgh over the course of five years, suggests that certain stars in the Orion Arm of the Milky Way (emit) radiation with unexpected frequencies for over a millennium. This phenomenon, cause remains unknown despite countless simulations, challenges existing theories about how stars evolve over time — particularly those in the later stages of their life cycles.

Dr. Eleanor Hart, who led the research, explained in a press conference: "We're observing patterns no computer model has predicted. It's as if the stars are communicating in a language (we) have yet to decode, sending signals that shift in ways we can't fully explain." Her team's findings, published in last month's International Journal of Astrophysics, have sparked intense debates in academic circles, with some experts questioning the accuracy of the data collection methods.

To address these doubts, researchers plan to replicate the experiment using advanced telescopes stationed at remote observatories in Chile's Atacama Desert, (hope) to collect data that will either confirm their initial conclusions or shed light on alternative explanations. "The universe is far more intricate than we once imagined," Dr. Hart noted in her latest paper. "Every breakthrough only reveals how much more there is to learn."

By next year, when the new high-resolution imaging system is fully operational, they (install) a state-of-the-art observatory in the Andes Mountains, where thin air and minimal light pollution create optimal conditions for studying faint stellar emissions. This facility is expected to revolutionize our understanding of cosmic radiation patterns, potentially unlocking secrets that have puzzled astronomers for decades.

Dr. Carlos Mendez, who led the expedition, spent weeks meticulously brushing away debris, his hands2 with a mix of excitement and caution.

The creature's skull, adorned with elongated horns, suggested it was a herbivore, yet its leg bones indicated a3 gait typically associated with predators.

This contradiction4 the research team. "We're looking at an evolutionary anomaly," Dr. Mendez noted, as he examined a5 of the rib cage under a microscope.

Local villagers, initially6 about the dig, soon grew curious. Children would peer over the excavation site's fence, their eyes wide with wonder as scientists7 more bones.

By the end of the third month, the team had8 a partial skeleton that spanned over six meters. Radiocarbon dating revealed the fossil was 75 million years old, a period when South America's ecosystem was undergoing dramatic9.

Dr. Mendez hypothesized that the dinosaur's unique traits were an adaptation to10 environmental conditions. Peer reviews initially11 the findings, citing inconsistencies in dating methods. But additional tests12 the original conclusions, prompting a flurry of research papers.

"This discovery rewrites our understanding of Cretaceous biodiversity," said Dr. Eliza Torres, a renowned paleontologist. The fossil, now on display at Buenos Aires' Natural History Museum, continues to13 visitors.

School groups gather around it, listening intently as guides explain how such a creature could have14 in prehistoric Patagonia. For scientists, it remains a puzzle — one that may15 our knowledge of dinosaur evolution for decades to come.

Reading is a fundamental skill that enriches our knowledge and broadens our perspectives. However, many people struggle to maintain consistent reading habits. With the right strategies, anyone can become a regular reader and enjoy the benefits it brings.

. Before you start, think about what you want to gain from reading. Do you want to learn new skills, explore different cultures, or simply relax? Your goals will help you choose the right books and stay motivated. For example, if you aim to improve your vocabulary, you might focus on literary classics or non-fiction works with rich language.

Create a reading schedule that fits your daily routine.. It could be 20 minutes in the morning before work, 15 minutes during your lunch break, or half an hour before bed. Consistency is more important than the amount of time you spend reading each day. Set a reminder on your phone or mark your reading time on a calendar to help you stick to the schedule.

Choose the right reading environment.. Some people prefer quiet places like libraries or their home study, while others enjoy reading in cafes with soft background music. Make sure your reading space is comfortable — have a good chair, proper lighting, and keep distractions like phones or TVs to a minimum.

Take notes while reading to enhance comprehension.. Write down key ideas, unfamiliar words, or questions that come to mind. You can use a notebook, sticky notes, or digital tools like e-readers with note-taking features. Reviewing your notes later will help you remember what you've read.

Finally, celebrate your progress.. Whether you finish a book, reach a reading goal, or discover a new favorite author, take time to acknowledge your achievement. Reward yourself with a trip to a bookstore, a new bookmark, or simply the satisfaction of knowing you're building a valuable habit.

A. Set clear reading goals

B. This makes reading more interactive and social

C. Everyone has different preferences for where they read best

D. Reading in short, regular sessions is more effective than long, occasional ones

E. Keeping track of your reading journey can motivate you to keep going

F. Not every book will resonate with you, and that's perfectly normal

G. This helps you engage actively with the text and retain information better

The core principles of ecotourism include minimizing environmental damage, respecting local cultures, and supporting conservation efforts. Travelers engaging in ecotourism activities typically visit protected areas such as national parks, wildlife reserves, or remote communities. They participate in activities like bird watching, hiking, or learning about traditional crafts from local residents. These experiences not only allow travelers to connect with nature but also contribute to the preservation of fragile ecosystems.

One successful example of ecotourism is the Galapagos Islands in Ecuador. Faced with threats from over-tourism in the 20th century, the government implemented strict regulations to protect the unique wildlife and landscapes. Today, visitors to the Galapagos must follow designated routes, be accompanied by certified guides, and pay a conservation fee that funds environmental protection projects. This approach has helped maintain the islands' biodiversity while providing income for local communities through tourism.

Another example is Costa Rica, often regarded as a leader in ecotourism. The country has transformed its natural resources into a sustainable tourism industry, with over 25% of its land protected in national parks and reserves. Tourists can explore rainforests, observe sea turtles nesting, or stay in eco-lodges that use renewable energy and support local farmers. This model has not only preserved Costa Rica's natural beauty but also reduced poverty in rural areas by creating jobs in tourism.

However, ecotourism is not without challenges. Some destinations market themselves as "eco-friendly" without implementing meaningful conservation measures, a practice known as "greenwashing." Travelers must be cautious and research companies before booking to ensure their tourism dollars support genuine environmental and community initiatives.

Additionally, even well-managed ecotourism can have negative impacts if visitor numbers exceed the carrying capacity of an area, leading to habitat disturbance or increased waste.

To practice responsible ecotourism, experts recommend choosing small-scale, locally owned accommodations, participating in guided tours led by local experts, and following the "leave no trace" principle by taking all trash with you and avoiding damage to plants and wildlife. By making informed choices, travelers can enjoy meaningful experiences while helping to protect the planet for future generations.

One of the most promising applications of AI in healthcare is medical imaging analysis. Machine learning algorithms can now identify patterns in X-rays, MRIs, and CT scans with accuracy comparable to trained radiologists. In a 2023 study published in The Lancet Digital Health, an AI system correctly detected early-stage lung cancer in 94% of cases, outperforming human experts by 8 percentage points. This technology enables faster diagnosis, especially in regions where radiologists are scarce, allowing patients to receive timely treatment.

AI is also accelerating drug discovery. Traditional drug development can take over a decade and cost billions of dollars, with a high failure rate. By analyzing large datasets of molecular structures and biological interactions, AI models can predict how potential drugs will interact with the human body, reducing the need for expensive laboratory experiments. For example, British pharmaceutical company Benevolent AI used AI to identify a potential treatment for amyotrophic lateral sclerosis (ALS) in just 12 months, a process that would typically take five to seven years.

Despite these advancements, several challenges hinder the widespread adoption of AI in healthcare. Data privacy is a major concern. Medical records contain sensitive personal information, and using this data to train AI systems raises risks of breaches or misuse. In 2022, a major healthcare provider suffered a data leak that exposed the medical records of over 1 million patients, many of which were being used to develop AI diagnostic tools.

Another challenge is algorithmic bias. AI systems learn from historical data, which may reflect existing inequalities in healthcare. For instance, an AI tool designed to predict patient risk of heart disease was found to underestimate the risk for female patients because the training data included more male patients. Such biases can lead to incorrect diagnoses or unequal access to treatment.

Additionally, integrating AI into existing healthcare workflows remains difficult. Many hospitals use outdated IT systems that cannot easily connect with AI tools, requiring significant investment in infrastructure. Healthcare professionals also need training to effectively use AI technologies, as over-reliance on algorithms without human oversight could compromise patient safety.

Looking forward, the potential of AI in healthcare is undeniable, but realizing this potential requires collaboration between technologists, healthcare providers, and policymakers. By establishing clear regulations for data privacy, addressing algorithmic bias through diverse training data, and investing in infrastructure and training, we can ensure that AI serves as a tool to enhance, rather than replace, human healthcare expertise.

But at the age of 14, a disaster struck. Lila fell during a practice session and broke her ankle. The doctor told her she might never dance again. Heartbroken, Lila threw away her ballet shoes and stopped attending her dance classes. She spent her days in her room, reading books and avoiding her friends. Her mother tried to encourage her, but Lila refused to talk about dancing.

Two years later, Lila's school announced a talent show. Her best friend, Mia, begged her to participate. "You don't have to dance," Mia said. "You could sing or play the piano." But Lila shook her head. She had lost interest in everything related to performing.

One afternoon, while cleaning out the attic, Lila found an old box of her mother's dance videos. Curious, she put one in the DVD player. There was her mother, young and graceful, performing on a big stage. Lila watched, tears streaming down her face. She remembered how happy dancing used to make her.

The next day, Lila went to see her former dance teacher, Ms. Sandra. "I want to try again," she said nervously. Ms. Sandra smiled. "I've been waiting for you to say that. Your ankle has healed, but we'll take it slow."

For months, Lila practiced for hours every day. It was painful at first, and she fell many times. But she refused to quit. Mia came to every practice, cheering her on. Her mother helped her stretch and massaged her ankle after each session.

On the day of the talent show, Lila stood backstage, her hands shaking. When her name was called, she took a deep breath and walked onto the stage. The music started, and she began to dance. At first, she felt nervous, but as she moved, all her fears disappeared. She danced with all her heart, just like she used to.

When the music stopped, the audience erupted in applause. Lila bowed, tears of joy in her eyes. Her mother and Mia were standing at the front, clapping and smiling proudly. After the show, Ms. Sandra hugged her. "You didn't just dance tonight, Lila. You showed everyone what courage looks like."

Lila knew then that some dreams are worth fighting for, no matter how many times life knocks you down.

Nobody  (like) to lose, but we must accept that losing is part of life. After , we can't win all the time. Although losing is unpleasant, it can be a positive thing. We can learn from every failure, which may help us succeed in the future. But first we must know how to be a good  (lose).

For one thing, we should take a positive attitude towards it. We can begin by realizing that losing is sometimes unavoidable. Therefore, we don't need to be  (embarrass). We must correct our mistakes and try again. As is  (know) to all, practice makes perfect. If we practise  (lose) by creating challenges for  (we), we will never be afraid of failure. For another, we should be polite when we lose. If we offer our  (congratulate) to the winner and share in his or her  (happy), our disappointment will  (certain) go away.

All in all, being a good loser will help us to succeed in life. It might be painful at first, but there are many benefits. Good losers should be respected and admired, most importantly, they win in the end.

A typical American high school has several large buildings and enough space for about 1,500 students.When students first arrive at school, they go straight to their lockers (寄存柜，有锁存物柜) to put away or get their textbooks and to hang up their outdoor clothes. As American textbooks are expensive, students would rather rent than buy them.

American students have different types of school transport. They usually take a yellow school bus or walk to school if they live close enough. When they turn 16 years of age, most take a free driving class at school for one term. If students earn passing grades in the class and also pass their state driver's exam, they can begin driving themselves to school.

They must take science, math, English and social studies. They can choose art, homemaking, fashion design and other classes. In some schools students are required to take one or more of the following special classes: health education, physical education or foreign language studies. Students move to different classrooms for each subject. This is because each teacher has their own classroom. There is a five-minute break between classes, to give the students the time to hurry to their next class.

The regular school day usually ends early in the afternoon. After school more than half of the students are involved in after-school activities. These activities include sports-especially football, basketball, baseball and soccer or clubs, such as yearbook, speech, school newspaper, photograph or student government.

A. Every student is given a locker.

B. Each day, students take six or seven classes.

C. Sometimes their parents drive them to school.

D. Students must pay back if they lost any of them.

E. Because each teacher has their own classroom.

F. In some schools students are required to take some special subjects.

G. This article will describe a typical American high school and its students.

The third-place winner was announced. The name was not mine. Then the second-place winner, still not me. At last, the moment of truth came. I was about to either enjoy the warmth of victory or regret the months' preparation. My heart felt closer to the latter.

Losing is a part of life, and I have dealt with it on more than one occasion. However, it was an indescribable feeling to drive a 200-mile round trip, get up very early on a freezing Saturday morning, and yet still finish fourth out of four competitors in my group.

I had spent many hours in front of a computer and in libraries doing research for the Lincoln Bicentennial (200周年) Speech Contest. After not placing (获得名次) in the first year of the contest, I really wanted to compete again. Lincoln had many failures, but he never allowed them to defeat his spirit or ambition, so I was not going to give up on a second contest! I reworked my speech for the following year, but again I did not place.

I couldn't accept the fact that I failed twice in something that I had worked so hard on, until I thought about my hero. Never mind the lost prize money and praise—through learning stories about Lincoln, I discovered that I can fail successfully.

We met in the Children's Hospital.I was 11. I was born with a hole in my heart. So was the five­year­old girl in the bed beside me.We were both recovering from the same operation.Because I was older and wiser, I thought it was my job to look after her. "Do you want to hear a story?" I asked her one afternoon."Great!" she said.

It was so easy to make her happy.She seemed always to be smiling or singing songs.

Life wasn't fair. She passed away. My recovery went well. "You're really lucky"，a nurse told me."But how come my operation was so easy and hers wasn't?" I asked."Easy?" my dad said. "David, your operation wasn't easy at all. We thought we were going to lose you. For two weeks after your operation, many things could go wrong. You're really lucky. When you were in the coma (昏迷) , she used to come over to your bed and sing to you. She was watching over you." my dad said.

My surgery scars (手术疤痕)are hidden under my shirt along with the memory of that kind little girl. She will be at my side like a small angel. I am old and wise enough now to know that I have an angel watching over me whenever life is fair or unfair.

Must-See Attractions

Most visitors begin their Amsterdam adventure in the Old Centre, which is full of traditional architecture, shopping centers, and coffee shops. You'll also want to check out Amsterdam's Museum Quarter in the South District, which is great for shopping at the Albert Cuyp Market and having a picnic in the Vondelpark. The top museums to visit there are the Rijksmusuem, the Ann Frank House, and the Van Gogh Museum.

If You Have Time

There are several other unique districts in Amsterdam, and you should try to explore as many of them as time allows. The Canal Ring is a UNESCO World Heritage Site that was originally built to attract wealthy home owners and is a center for celebrity spotting and nightlife today. The Plantage area has most of the city's museums and the botanical gardens.

Money Saving Tips

●Unless you really want to see the tulips(郁金香) blooming, avoid booking between mid-March and mid-May. This is when hotel and flight prices rise.

●Look for accommodations in Amsterdam's South District, where rates are generally cheaper than in the city center.

●Buy train tickets at the machine instead of the counter to save a bit of money.

●Instead of hiring a tour guide, hop on a canal boat. They're inexpensive and will give you a unique point of view of the city.

The Ice Cream Truck

"Never give up! Never give up!" chanted two young children, Max and Lily, as they marched barefoot behind their grandmother Mimi who was leading them on a great adventure, straight off the beach where they had spent the day building sand castles and swimming in the sea. They were seeking the mysterious ice-cream truck!

Over the years, Mimi had become an example of positivity for her family. It was not a title she earned without effort, however. Her husband died early and at only forty years old she was left to raise her daughter alone. She faced the heart-breaking disaster powerful enough. She could have lived under a black cloud. But she challenged herself to find joy every day instead. She was always up for a new challenge, whether that was hiking across the rocky mountain in Austria to get a better view of the breathtaking scenery, or signing up for tap-dancing classes at fifty. Leading by example, Mimi taught her daughter just how much one could achieve with a positive attitude.

And obviously she had taken the same approach in her relationship with her grandchildren as well. Before starting her adventure with Max and Lily on that hot July afternoon, Mimi heard the ice-cream man's bell from her beach chair. She turned and saw him briefly, spotting his green shirt and catching the sight of his waving bell before he turned and disappeared. The ice-cream man visited the beach on a daily basis, although the delay between the sound of his bell and the disappearance of his truck was not long. One must be quick to catch him.

Max and Lily were disappointed when they didn't catch him in time that day. That was until Mimi's eyes shone and she said, "Never give up!" She explained that the truck might be gone, but they could hurry up to find it at its next stop.

They walked block after block. Not knowing which direction the truck had taken, they had to make their best guess about where to search. The kids' tiny legs were tired, but they went on, continuing the chant, "Never give up! Never give up!"

In the West, many individuals express their appreciation for traditional Chinese art in their own unique ways. Ann Massing, a famous watercolor (paint)has devoted over 40 years to art restoration.

Since her first visit to China in the 1980s, Massing has developed deep interest in traditional Chinese scholar painting. the guidance of Peter Cavaciuti, a British-Italian artist and disciple(追随者)of the famous Chinese art master Xu Beihong, she devoted herself to the study of Chinese ink painting and her own unique artistic expression (create)after a couple of years of study. Through her (publishing)works, such as "A Journey Eastwards: Reflections on Chinese Ink and Watercolour Paintings", Massing （vivid）illustrates the profound impact of cross-cultural artistic exchange.

In a recent interview with People's Daily Online, Massing shared her vivid insights on (China)rapid transformation. She believes that the fusion(融合)of Eastern and Western artistic traditions not only (enrich)individual creativity, but also can be of   great help to (globe)cultural exchange. She stresses that cross-cultural artistic dialogue contributes to innovation and enhances mutual(相互的)understanding, plays a vital role in promoting harmony across diverse communities worldwide.

I often saw Lisa practice alone, dribbling (运球) and4 over and over again, sometimes until dark. I asked her why she worked so hard. Without a moment of5 she said, "I want to go to college. The only way I can go is to get a6".

One day, I saw her sitting in the grass, head in her arms. I went over and sat down beside her,7 what was the matter. "Oh, nothing." came a8 reply, "I am just too short.

● Avoid offering help in exchange for approval

Popular people often help others, but being helpful doesn't always make you more popular. Trying to be helpful just to make others like you will backfire (事与愿违). . You'll come across as needy, which isn't attractive.

●

The most popular people are often the ones who hold their friends together. Try to arrange parties and get - togethers where your friends can hang out together. You will also be considered as a more social person.

● Be easygoing

When you are easygoing, your friends will enjoy spending time with you, which may make you more popular. .

Sharing your problems with others is a good thing, but talking about your problems over and over again is annoying and your friends will keep away from you.

● Stop talking about people behind their backs

. When you speak negatively about other people, the person you're talking to can reasonably assume that you would speak negatively about them when they're not around. Even if you attempt to justify your unfriendly behavior by saying "I'm not talking behind anyone's back. I'm just telling the truth." While this may be the case, it is still not an acceptable excuse.

A. Be the glue in your social circle

B. These qualities draw others towards them

C. It's unpopular to talk back when friends are around

D. People who often complain about life have fewer friends

E. It's important to have a positive attitude and avoid constant complaining

F. They will know that you need friendship or approval from them in return

G. Popular people know that talking behind people's backs will cause them to lose friends

Although the term "Artificial Intelligence" wascoinedin 1956, its origin began in ancient times with stories of artificial beings with intelligence. Since ancient times, humans have been crazy about building artifacts that could copy human intelligence. For example, in Ancient Greece, there are references to stories of self-acting devices created by skilled workmen, designed for simple tasks, copying basic human actions. These artifacts laid the groundwork for the development of intelligent machines.

Over centuries, the idea of building intelligent machines progressively developed, driven by advances in science and technology. In the 19th century, scientists and inventors such as Charles Babbage and Ada Lovelace made significant contributions to the development of computing and the early concepts of programming. Their ideas paved the way for the creation of machines that could process information logically and perform complex tasks.

It was in the second half of the 20th century that AI, as a scientific subject, began to establish itself. With the coming of modern computers and increasing processing power, scientists started exploring algorithms (算法) and techniques to simulate aspects of human intelligence. The first experiments with expert systems and machine learning opened up new perspectives and possibilities.

After about 60 years of inactivity, in the early years of 21st century, AI is starting to have its moment. The power of machines, combined with the Internet, has made it possible to generate and explore enormous amounts of data (Big Data) using deep learning techniques, based on the use of formal neural (神经的) networks. A range of applications in various fields — including voice and image recognition, natural language understanding, and autonomous cars — has awakened the "giant". It is the rebirth of AI in an ideal era for this purpose. The perfect moment!
