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 Many hospitals use outdated IT systems that cannot easily connect with AI tools, requiring significant investment in infrastructure.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.

A couple of years back, when I was still a teenager, I was troubled by frequent headaches that felt like I wanted to bang my head against a hard surface. I was eager to find a way to stop them. If you've been through this, I can feel your silent nod; for those who haven't, let me tell you, it's truly painful.

I had exhausted all possibilities. Sadly, none provided a lasting relief for my tormenting pain. In my desperation, my dad suggested I try acupuncture (针灸), something he once underwent in Hong Kong. It had relieved his backache when nothing else worked.

I was unfamiliar with acupuncture and hadn't tried out traditional Chinese medicine before. With my heart set on previous failures, I embarked on this acupuncture journey, ending up in a middle-aged lady's clinic filled with Chinese herbs.

Once I settled on the patient's chair, she inquired about my reason for visiting. After that, she placed three fingers on my wrist and silently checked my pulse. She then led me to a room and instructed me to lie down. Moments later, she took out needles, which made me anxious because I'm not comfortable with sharp objects.

The initial acupuncture session was a real surprise. To treat my headaches, the needles were first placed on the back of my hand, far from my head. The sensation was unexpected too: as the practitioner gently tapped and turned the needle in, I didn't feel the needle but a wave spreading through my body. She then continued with more needles all over: my head, face, stomach, legs, arms, and even toes. The entire session lasted just 20 minutes. Following that, she prescribed some herbal tea for me to drink daily for five days.

For thousands of years, Chinese people (value) the large family with three, four, or even five generations living under the same roof. In this way of life, the older generation can enjoy a happy and easy late life with their children, grandchildren or great-grandchildren growing up beside them and keeping them being lonely. However, as society advances and people enjoy a (comfortable) life, the big families begin to break up. Along with the growth of so-called "empty nestles", which means the young birds have flown away and only old are left alone, young parents are living with their own nuclear families. It goes without saying the collapse of big families and the popularity of smaller ones are the result of our times.

It is a time when people think highly of individual freedom happiness. Young people like to have a space all alone to themselves, which helps avoid conflicts (cause) by different living habits from their parents. It's also a time when problems of old age and childcare have been socialized gradually. Senior citizens can live together and (take) good care of by specialized nurses.

Therefore, there is every reason to believe that this trend of families in reduced size is (agree) to our times. To create a brighter future, we should do our best to build our society into one in every member lives healthily and harmoniously.

However, the4 of working from home gradually set in. I had started my day with the best intentions, promising myself quick breaks and regular5. But deadlines, endless emails, and virtual meetings6 me to my computer throughout the day, leaving me little time to7. Gone were the short walks to a colleague's desk and the quick lunchtime walks around the office complex. Finally, my world was8 to the walls of my home, my steps9 in mere meters rather than kilometers.

One day, I tried10 one of my favorite dresses and it wasn't passing through my waist at all. Glancing at myself in the mirror, I saw a11 person carrying extra weight, rather than someone enjoying freedom. The12 of work and personal life had left me feeling like I was a never ending motion machine.

This incident marked the13 of a journey of self-discovery. I made up my mind that I needed a(n)14 not just for my waistline but for my overall well-being. It was a promise to prioritize my physical and mental health, and a commitment that I could15 control over my life and my body.

Notice the structure. Poems aren't just words on a page. Their form, including rhyme schemes, stanza breaks, and line lengths, contributes to meaning. A tightly structured poem might evoke (唤起) order, while broken lines could reflect chaos. Don't overlook punctuation (标点) or capitalization.

Engage yourself in imagery and metaphor. Poets paint pictures with words, so visualize the scenes they describe. Ask: What senses are engaged? A poem about rain might feel cold and damp. Figurative language like similes and metaphors invites you to explore deeper connections between seemingly unrelated ideas.

Consider the poet's perspective. Who is speaking? Is it the poet's voice, a character, or an abstract being? Understanding the "speaker" can clarify the poem's intention. Historical events, personal experiences, or cultural symbols may influence its meaning.

Poetry grows on emotion, and there's no "correct" interpretation. Your response — whether joy, sorrow, or curiosity — is acceptable. Revisit the poem: meanings often change with each reading. Take down questions it raises, and research unfamiliar references if they interest you.

In short, appreciating poetry is an adventure of discovery. Slow down, listen, and trust your feelings. Rather, it's about appreciating the interplay of sound, image, and idea that makes poetry timeless.

A. Let yourself feel.

B. Context matters as well.

C. Don't be afraid of making mistakes.

D. These shape how you stop and interpret.

E. Pay attention to how words flow together.

F. The poem's background determines the style.

G. This is not like unlocking a "secret password".

We have much to learn from these children.

That's what art therapist(治疗专家), Lisa Murray, believed as she worked to help children with cancer to release their feelings through their drawings, which have turned into a book, Angels & Monsters.

Murray found that in their struggle, kids would tell her constantly, "I'm just a regular kid; I just want to play, to go to school, to go outside. . . I just happen to have cancer. "

She was moved and inspired by their simple will to survive. The children were facing the disease head on. She saw some powerful images in their artwork. "What courage it takes to do that, " said Murray.

Murray selected 25 children aged 13 months to 18 years. She asked the four- year-olds and up, "If you could tell the world what it is like to have cancer, what would you say, what would you draw?" For two- to three-year-olds, she asked, "What do you want to tell people about yourself?" And for the youngest, she just took their handprints. "It's such a human expression, ‘Here's my mark, ‘" said Murray.

She then asked them about their pictures, and wrote down exactly what they said. This gave the artwork a powerful voice. Coupled with Murray's photographs of the children in the book, the three forms of expression leave both a permanent record and lasting impression with the viewer.

As a therapist, Murray doesn't give the kids the impression that the drawing process is right or wrong. Whatever they draw is unconditionally acceptable. "Children play, they draw, and that's the natural language of children. That's why art therapy is so wonderful, "she said.

Seven of my sisters and brothers had flown out of the family, but my brother Wayne was the only one with kids. He and his wife had just been transferred across the country to California. Mom was looking at her first Christmas without little ones in the house. She was a little depressed.

On Christmas Eve we sat talking about my little nieces, wondering what they were doing. We imagined how empty the next day would be without them opening presents. When we couldn't stand it any longer, we called and passed the phone around, asking them if they had been good girls and what they hoped Santa would leave under their tree. Mom then busied herself in the kitchen.

That was when something terrible happened. We lived on a busy state highway in south Louisiana, on a section of a dangerous road. The sound of screaming tires (轮胎) wasn't unusual to us. Many strangers asked us for help and stayed in our living room while waiting for an ambulance, a tow

truck (拖车) or a family member to rescue them.

As we hung up from talking to our nieces, we heard the familiar sound of tires screaming. We held our breath, and then heard a loud crash. We rushed out to the road. A truck had hit a car holding a young couple and their two little daughters. The truck driver and the young family climbed out of the terribly damaged vehicles. Amazingly, no one appeared hurt.

Mom and Dad welcomed them into the house and Mom started warming dinner. Later, someone picked up the truck driver. But the family was stranded (滞留). They were on their way to Mississippi to spend Christmas with elderly grandparents who were too old to drive and pick them up this late night. Within five seconds we all fell in love with the precious girls. The older girl was three just like my older niece, and the baby was a few months younger than our little one.

88-year-old Ploutarchos Pourliakas crossed the finish line at the 41st Athens Marathon on Sunday, (prove) once again that age is no match for determination.

The epic annual race, famously known as The Authentic, traces is believed to be the original path taken by Athenian messenger Pheidippides, who ran from the battlefield of Marathon to Athens over 2,500 years ago (deliver) news of victory.

This year, he completed The Authentic marathon for the (twelve) time, finishing the race in an (impress) 6 hours and 31 minutes — 18 minutes faster than his time last year.

Pourliakas' journey as a marathon runner (begin) at the age of 73, inspired by his son, an ultramarathon runner. Since then, he (challenge) expectations and surprised many who find it hard to believe that an octogenarian (八旬老人) could still be racing.

Pourliakas' achievement serves as an inspiring (remind) that it's never too late to start something new. The octogenarian runner often leaves people amazed, many struggle to believe his age when they see him run. response, Pourliakas says, "Why wouldn't you believe it? We all can do it."

It's becoming more and more important for us to think about the impact that4 can have on our environment. This was the5 for my bicycle tour: I wanted to find more responsible ways to protect the planet and6 traveling by plane where possible.

I discovered that bicycle touring is one of the most7 ways to travel, as using nothing but a bicycle and your own pedal (脚踏) power, you can8 everything you need while covering surprising9 each day.

The10 of life and the free time I spent just cycling alone gave me a lot of time to11. This really helped me to learn a lot about myself. So I've managed to12 a lot of problems from my past and feel that my confidence and independence have13.

Finally, I arrived in Istanbul with a huge mixture of14 over the past three months: loneliness, joy, liberation, pride and anxiety. As a result, the journey makes me feel like a15 person. What a cycling trip to remember!

It has been four years since I quit my corporate job and gave myself a chance as a freelance   writer. However, the reason behind quitting was also the same: I had seen that many people are working as freelancers nowadays, and I had heard a lot about it. .

Initially, it was a bit difficult for me. I almost took it as a wrong decision. Compared to other freelancers, I was new to this. . Instead, they prefer to sign the contract with someone they have previously worked with. So, it took time and almost more than a month to get my first project.

. The first work I did was for $16 per hour, but I learned here that it shouldn't be about making money in the beginning but growing your network by taking more and more projects, whether small or big and so I followed it. Thankfully, the clients appreciated my first project enough, so it didn't take much time to get me another project.

And, then, after going on like this, with the extremely hard work of 4 - 5 months, the amount of work for me started to increase. . Some of the clients from my corporate network were also part of it, so it didn't take much time for me to get excellent and promising projects that were even worth $80 - $90, sometimes for an hour and more than this, in urgent cases.

My favorite part as a freelancer was the flexibility I gained. I can do the work at my pace if the client has no urgency. As a freelancer, I didn't have to ask for holidays. Whenever I wanted, I could take them without asking for permission. . As a freelancer, it's important to keep working so your managed network can stay yours always. If you start delaying the work or always remain on holiday, it will affect the quality as well as the quantity of your work.

A. But one thing is for sure.

B. From here, my journey started gradually.

C. And clients rarely select a new freelance writer.

D. The entire process made me feel like a boss every day.

E. On the other hand, I was also looking to switch my job.

F. Gradually, I started to enjoy it as I made money and was paid for every hour.

G. These were the starting days when I got to put in lots of effort to get more work.
