I rushed to the back of the ambulance before I thought to fasten my seat belt as our ambulance dashed down the road. My legs trembled uncontrollably as I felt around for boxes of gloves and passed them to the rest of the crew. Despite my jumpy nerves, I felt a thrill. Here I was, on my first real call after three months of training.
We pulled up to the scene and I jumped out, feeling official and important at having arrived in such style. As we approached the patient, we saw the terrible scene, but the two emergency workers with me were prepared. One immediately began treating the patient while the other calmed the anxious family. I was asked to give breaths to the patient while a worker did chest compressions (按压).
Though I agreed, my excitement and nervousness disappeared as I felt the gravity of the situation. This person’s life was in my hands. For the next 20 minutes the emergency workers and I counted breaths and compressions, occasionally switching positions. We continued administering CPR for the whole of the rough ride to the hospital and I grew increasingly alarmed since the patient was not responding.
Arriving at the emergency room, we knew it was over. My first call, my first chance to save someone, but I failed. I was horrified. A complete stranger had died before my eyes, under my care. The doctors comforted me, and though I felt responsible, I soon realized that there was nothing we could have done to change the result. Our CPR technique had been sound, but the reality was that the chances of life after a heart arrest were very slim.
As the initial shock wore off, a strong motivation to go on another emergency call replaced it. Watching life turn into death is not an easy experience to forget, but it can create a thirst to try again and perhaps save a life the next time. Unfortunately, or perhaps fortunately, the chance hasn’t yet happened. The worst call I’ve had since that first day is a twisted ankle.

【推荐1】It was blazing hot, just like most July days. I stepped into a tiny ice-cream shop to cool off with a chocolate ice-cream. It was an old woman bent over a table near the door. Her back was so badly twisted that her face nearly touched the tabletop. I sat down facing her a couple of tables away.
“Poor woman,” I thought, “What does she get out of life? Why God let people live so long past their prime?”
As I thought, another aged lady entered the shop and sat down with her. Soon the two of them were talking about childhood days. They talked of how little the shop had changed in 70 years. In minutes, the two of them were trembling with laughter.
I looked again at the first woman, then in the mirror on a nearby wall, catching a picture of myself. I was wearing a dirty shirt. She was well dressed in white, her hands sparking with gold rings. I was sad. She was laughing, smiling. I was putting the pieces of my life together. She had millions of wonderful memories to recall. I sat alone. She was sharing the day with a good friend. I was secretly worried about getting old. She was old, but it wasn’t hurting her.
As I left the shop, I thought of my foolish question about God letting people live past their prime. Why, that woman was more alive, more sensitive to life than I was. Age has not bent her spirit.

【推荐2】There is something to be said for being a generalist, even if you are a specialist. Knowing a little about a lot of things that interest you can add to the richness of a whole, well-lived life.
Society pushes us to specialize, to become experts. This requires commitment to a particular occupation, branch of study or research. The drawback to being specialists is we often come to know more and more about less and less. There is a great deal of pressure to master one’s field. You may pursue training, degrees, or increasing levels of responsibility at work. Then you discover the pressure of having to keep up.
Some people seem willing to work around the clock in their narrow specialty. But such commitment can also weaken a sense of freedom. These specialists could work at the office until ten each night, then look back and realize they would have loved to have gone home and enjoyed the sweetness of their family and friends, or traveled to exciting places, meeting interesting people. Mastering one thing to the exclusion(排除)of others can hold back your true spirit.
Generalists, on the other hand, know a lot about a wide range of subjects and view the whole with all its connections. They are people of ability, talent, and enthusiasm who can bring their broad perspective(视角)into specific fields of expertise(专长). The doctor who is also a poet and philosopher is a superior doctor, one who can give so much more to his patients than just good medical skills.
Things are connected. Let your expertise in one field fuel your passions in all related areas. Some of your interests may not appear to be connected but, once you explore their depths, you discover that they are. My editor Toni, who is also a writer, has edited several history books. She has decided to study Chinese history. Fascinated by the structural beauty of the Forbidden City as a painter, she is equally interested to learn more about Chinese philosophy. “I don’t know where it will lead, but I'm excited I'm on this pursuit.”
These expansions into new worlds help us by giving us new perspectives. We begin to see the interconnectedness of one thing to another in all aspects of our life, of ourselves and the universe. Develop broad, general knowledge and experience. The universe is all yours to explore and enjoy.
1. To become a specialist, one may have to ________.| A．narrow his range of knowledge |

【推荐3】Growing up, I understood one thing about my dad: he knew everything. This was our relationship: I asked him questions and he told me the answers. Is there really a man in the moon? How do sailboats work? In my teen years, he taught me things I’d need to know to survive in the real world. How to check your car. The correct knife to bring along.
When I moved out, I called him at least once a week, usually when something broke in my apartment. After I got married, I needed him less because I had my husband and Google. When I called our conversations changed into six words. Me: “Hi, Dad.” Him: “Hi, sweets. Here’s Mom.” (Because I still needed her - How do I cook chicken? Do I need to call the doctor for my daughter’s fever?) I loved my dad, of course, but I wondered at times if maybe he had already shared everything I needed to know. Maybe I’d heard all his stories. Maybe, after knowing a man for 30 years, there’s nothing left to say.
Then, this past summer, my husband and I moved in with my parents for three weeks while our house was being repaired. They own a lake house, and Dad asked me to help him repair the walls. I didn’t balk— it was the least I could do for free rent(房租) — but I felt anxious. It was difficult. We got wet and sandy. But as we rebuilt the walls, my dad knowing exactly what went ______. I looked at him, “How do you know how to build walls?”
“I spent a summer in college building them.” “You did?” I thought I knew everything about my dad, but I never knew this. “Yep. Now let me teach you how to use this saw(锯子).” As he explained the skills, I realized that maybe it’s not that there’s nothing left to say. Maybe it’s just that I’ve spent my life asking him the wrong questions.
A few weeks later, after my family moved back into our own house, I called my parents. Dad answered. “Hi, sweets,” he said. “Here’s Mom.” “Wait, Dad,” I said. “How are you?” We ended up talking about work he was doing. Nothing life-changing. To anyone else, it would sound like a normal conversation between a dad and his daughter. But to me, it was a new beginning. I spent the first part of my life needing to talk to my dad. Now I talk to him because I want to.

【推荐1】What will you do when you feel like a failure? Feeling like a failure is part of the human experiences. Treat yourself with kindness and understand that failure does not define you, but it is a stepping stone on your journey. When you’re ready, take action and challenge yourself.
As some friends were deeply lost in the world of yoga and mindfulness, I’ve personally struggled with the feeling of failure, not on the yoga mat, but on the road to my entrepreneurship(创业). It all began several years ago when I threw myself into the business, driven by my passion and a dream.
In the early days, optimism flowed freely, but financial struggles and sleepless nights soon followed. I questioned my decision and felt like the biggest failure. However, every difficulty became a stepping stone towards growth. I learned more from my failures than from my successes, adapting and growing stronger with each obstacle. I reached out to instructors, friends and family, sought advice and slowly saw a ray of hope. One defining moment came when I gained my first long-term coaching partnership. It was a breakthrough, and my hard work paid off. Over the years, I faced many more failures, but I refused to let them define me.
Today, looking back at my journey, I realize that moments of feeling like a failure were essential to my success. They taught me humility, perseverance and the value of hard work. They shaped me into a successful entrepreneur I am today—someone who doesn’t fear failure but embraces it as a necessary part of the path to success. As we approach the end of the year of graduation, remember that success is not about avoiding failure, but about how we rise after we fall. Let’s support each other on this journey called life. Stay positive, stay inspired and stay true to ourselves.

【推荐2】Last year, as my then-9-year-old son, Leopold, and I were on a series of adventurous trips, I came up with a rule: We would say yes to everything as much as feasibly possible. Leopold is a picky kid — he feeds only on chicken nuggets and yogurt — and can be reluctant to try new things. According to him, it’s because he has numerous fears, including heights, spiders and the dark. But honestly, I suspect he just has normal kid-sized nerves.
My original goal was simple. I was hoping to find a way to encourage him without resorting to worn-out words like “if you don’t try it, you’ll never know if you like it.” So, I borrowed the idea of a “yes day”. Leopold and I agreed we would say yes to everything — including food and experiences, especially new ones.
In St. Augustine, Florida, we collectively said yes to a moonlit ghost tour of the city’s famous haunted sites, where while others got claustrophobic (幽闭恐惧的) and left during the telling of ghost stories, Leopold and I stayed until the bitter end and didn’t even scream when one of the actors attempted to frighten us with a jump scare. On that same trip, Leopold tried his first spicy tuna roll and then experimented with blackened grouper (石斑鱼). In Long Sands, Maine, I challenged myself to jump into the freezing ocean, getting cold and wet, but happy to be foolish enough to jump into the chilly waters. On the last night of our trip at a rodeo where cowboys showed their skills at handling bulls in Cody, Wyoming, my son did not hesitate but went onto the field to take part in this traditional event. Though coming back without the prized bandanna, he was laughing loudly, sweaty and excited. I knew it was an experience we would never forget.
And therein lies the beauty of saying yes on vacation. It pushes you to be open to new opportunities and step out of your comfort zone. Though it’s not always possible to say yes to everything back home, where work, school and other obligations get in the way, we’ve begun trying to say it more. Cultivating a sense of curiosity and adventure helps all of us live life to the fullest with zero regrets — even if you do sometimes wind up cold and wet, sweaty and tired.
1. What can we learn about Leopold from the first paragraph?| A．He avoided new attempts. | B．He longed for adventures. |
| C．He was fond of travelling. | D．He enjoyed varieties of food. |
| A．They tried freediving. | B．They kept their promise. |

【推荐3】I had an experience some years ago, which taught me something about the ways in which people make a bad situation worse by blaming themselves. One January, I had to hold two funerals for two elderly women in my community. Both had died “full of years”, as the Bible would say. Their homes happened to be near each other, so I paid condolence(吊唁) calls on the two families on the same afternoon.
At the first home, the son of the deceased(过世的)woman said to me, “If only I had sent my mother to Florida and gotten her out of this cold and snow, she would be alive today. It’s my fault that she died.” At the second home, the son of the other deceased woman said, “If only I hadn’t insisted on my mother’s going to Florida, she would be alive today. That long airplane ride, the sudden change of climate, was more than she could take. It’s my fault that she’s dead.”
You see that any time there is a death, the survivors will feel guilty. Because the course of action they took turned out bad, they believe that the opposite course—keeping Mother at home, putting off the operation—would have turned out better. After all, how could it have turned out any worse?
There seem to be two elements involved in our willingness to feel guilty. The first is our need to believe that the world makes sense, that there is a cause for every effect and a reason for everything that happens. That leads us to find patterns and connections both where they really exist and where they exist only in our minds.
The second element is the view that we are the cause of what happens, especially the bad things that happen. It seems to be a short step from believing that every event has a cause to believing that every disaster is our fault. The roots of this feeling may lie in our childhood.
A baby comes to think that the world exists to meet his needs, and that he makes everything happen in it. He wakes up in the morning and summons the rest of the world to his tasks. He cries, and someone comes to attend to him. When he is hungry, people feed him, and when he is wet, people change him. Very often, we do not completely outgrow that childish view that our wishes cause things to happen.

【推荐1】When I was a kid in Minnesota, watermelon was a delicacy(美味). One of my father's buddies, Bernie, was a successful fruit-and-vegetable wholesaler, who operated a warehouse in St. Paul.
Every summer, when the first watermelons rolled in, Bernie would call. Dad and I would go to Bernie's warehouse and take up our positions. We'd sit on the edge of the dock, feet dangling（摇晃）, and lean over, minimizing the volume of juice we were about to spill on ourselves.
Bernie would take his machete（刀）, crack our first watermelon, hand us both a big piece and sit down next to us. Then we'd bury our faces in watermelon, eating only the heart - the reddest, juiciest, firmest, most seed-free, most perfect part - and throw away the rest.
Bernie was my father's idea of a rich man. I always thought it was because he was such a successful businessman. Years later, I realized that what my father admired about Bernie's wealth was less its substance than its application. Bernie knew how to stop working, get together with friends and eat only the heart of the watermelon.
What I learned from Bernie is that being rich is a state of mind. Some of us, no matter how much money we have, will never be free enough to eat only the heart of the watermelon. Others are rich without ever being more than a paycheck ahead.
If you don't take the time to dangle your feet over the dock and chomp into life's small pleasures, your career is probably overwhelming your life.
For many years, I forgot that lesson I'd learned as a kid on the loading dock. I was too busy making all the money I could.
Well, I've relearned it. I hope I have time left to enjoy the accomplishments of others and to take pleasure in the day. That's the heart of the watermelon. I have learned again to throw the rest away.
Finally, I am rich.

【推荐2】In Asia, the best food is found not in fancy restaurants, but in the carts and stalls lining busy streets. These following snacks are not only local to their city or country, but also show the delicious range of structure and flavour.
Xiaolongbao-Shanghai, China
Shanghai’s Xiaolongbao is filled with pork and aspic, which makes it special. Aspic is a meat combination that melts into soup when heated. As a result, the tiny buns are tasty and salty. They are found throughout the city, so people enjoy standing up at street stalls and restaurant-fronts by Shanghai's business set.
Pho-Hanoi, Vietnam
Pho is noodle soup. Ingredients in the soup are simple: noodles, meat (chicken or beef), and garnishes (green onion, Thai basil, lime and chilis). But what really sets pho apart is its soup, made by simmering bones with onion and ginger, spices and seasonings, ideally for hours on end to get the flavour just right.
Penang AsamLaksa-Penang, Malaysia
Penang AsamLaksa is spicy noodle soup made with thick rice noodles. The dish is made more notable with the addition of lemongrass, spicy (辛辣的) chilis, sweet pineapple, cilantro, onions and fresh mint garnishes. Penangites have loved their asam laksas for some time and with their loving additions to their favorite recipe.
Som Tam-Bangkok, Thailand
This fruit salad is a mix of papaya, a local fruit,and the following ingredients:sugar, chilis, fish sauce, garlic, tomato, among others. This dish is not sweet like you might expect, but sour, salty or spicy in equal measure. Local variations add in everything from peanuts to crab, but in Bangkok you'll find the spiciest versions, which can be as challenging to eat as they are delicious.

【推荐3】If you wear glasses, chances are you are smarter. Research published in the famous British journal Nature Communications has found that people who displayed higher levels of intelligence were almost 30 percent more likely to wear glasses.
The scientists studied the genes of thousands of people between the ages of 16 and 102. The study showed intelligence can be connected to physical characteristics. One characteristic was eyesight. In out of 10 people who were more intelligent, there was a higher chance they needed glasses. Scientists also said being smarter has other benefits. It is connected to better health.
It is important to remember these are links which are not proven causes. Scientists call this correlation. Just because something is linked with something else does not mean one of those things caused the other. And it’s worth noting that what constitutes intelligence is subjective and can be difficult, if not impossible, to measure.
Forget genes though. Plenty of proof shows wearing glasses makes people think you are more intelligent, even if you do not need glasses. A number of studies have found people who wear glasses are seen as smarter, hard-working and honest. Many lawyers use this idea to help win their cases. Lawyer Harvey Solves explained this. Glasses often their appearance. He said sometimes there has been a huge amount of evidence showing that the clients he was defending broke the law. He had them wear glasses and they weren’t found guilty.
Glasses are also used to show someone is intelligent in movies and on TV Ideas about people who wear glasses have begun to shift. People who do not need glasses sometimes wear them for fashion only. They want to look worldly or cool. But not everyone is impressed by this idea, though. GQ magazine said people who wear glasses for fashion are trying too hard to look smart and cool. However that hasn’t stopped many famous people from happily wearing glasses even if they do not need them. Justin Bieber is just one high-profile fan of fashion glasses.

【推荐2】Do you know that nearly every home in America contains a microwave? While microwaves make meals for busy people in several seconds, is microwaving food bad for you? Over the years，this standard household appliance(家用电器）has caused much discussion. Some argue microwaves kill nutrients in your food. Is that really true?
In reality, anytime food is exposed to heat, nutrients like vitamin C and some antioxidants (抗氧化剂) can be lost. But this applies to cooking in general, not just when you’re using microwave. As is reported by WHO (World Health Organization), microwaving your food is a safe way to prepare it and it keeps the same level of nutrients as when you cook on a stove top or in the oven(烤箱).
When microwaving thicker food like meat products, WHO provides the following suggestions to ensure safe cooking methods: Cooking time will vary depending on the food itself and the power of the microwave, and will also be affected by the density of the item you are heating. Since microwave heating doesn’t evenly(均匀地)go into thick food items, meat that’s not thoroughly cooked may contain harmful microorganisms that make you sick. To kill harmful bacteria when cooking in the microwave, WHO suggests letting your food “rest” for several minutes after you finish warming it to allow the heat to give off throughout the item.
If you’re thinking about microwaving your vegetables, Harvard Health Publishing suggests heating your food rapidly, in the shortest amount of time, and as little amount of water as possible. As far as vegetables are concerned, cooking them in water robs them of some of their nutritional value because the nutrients run out into the cooking water," states the report.

【推荐3】Most humans are able to recognize about 1 million different colors, but some people can't recognize this many because of something called colorblindness(色盲). In rare cases, some people can't see any colors at all.
There are three cone-shaped(锥形的)cells at the back of our eyes that allow us to see colors. These cells absorb tight waves and send a message to the brain, where the image is processed.
If something is wrong with these cone-shaped cells, this can result in colorblindness.
Thankfully, special color-correcting glasses have already been made to help fix some types or colorblindness. Now, according to research published in Optics Letters, scientists have provided another choice.
Sharon Karepov and Tal Ellenbogen, engineers from Tel Aviv University in Israel, have found a way to apply this technology to contact lenses(隐形眼镜). This is good news for the millions of people worldwide who suffer from colorblindness.
One of the most common types of colorblindness is red-green colorblindness. People who have this specific type have difficulty telling the colors red and green apart. "Problems with distinguishing red from green stop simple daily routines such as deciding whether a banana is ripe," Karepov explained.
Karepov also stressed the importance of applying this finding to create special contact lenses instead of relying on color-correcting glasses.
"Glasses based on this correction concept are commercially available. However, they are too big than contact lenses." Karepov said. "Our contact lenses create a customized, compact and durable(耐用的)way to deal with these shortcomings."
This new research is groundbreaking. In addition to offering those who are colorblind another option, it may lead to solutions for other visual damage.
