1 . What are scientists?They are often described as gray-haired white-coated dull scholars.

But the world has changed.Young scientists are making their voices heard and releasing their powers on the world stage.

This is also true in China.Rising stars include new materials expert Gong Yongji,university professor Liu Mingzhen,and biologist Wan Ruixue.At the age of 28 in 2018,Wan Ruixue received the 2018 Science & SciLifeLab Prize for Young Scientists.This is a global prize to reward outstanding scientists at an early stage of their careers.

She focuses mainly on biomedicine (生物医学) and artificial intelligence.“Both are cutting-edge (前沿) technologies at an early stage of development,” she said.

“So,I think they have great potential to be developed.I think in the study of cutting-edge technologies,China and other leading countries in the world are standing on the same starting line.And in the study of structural biology,China is likely to become the leader.”

She felt it was her fate to become a biologist.“I grew interested in the natural world,when I was very young,” she said.In 2009,she entered Sun Yat-sen University.

In her third year at the university,she realized that she wanted to do something related to biomedicine.So she emailed China’s top biologist Shi Yigong,hoping to join his lab at Tsinghua University.

Shi recognised her talent and welcomed her.Years of efforts at the lab have paid off.Her research on the high-definition 3D structure of spliceosome led to a scientific breakthrough.

Unlike many of other young scientists who choose to pursue further study abroad,Wan currently has no plan to go overseas.

“The whole ecosystem for scientific research is continually improving in China,” she said,adding that the country has great science facilities.

2 . Books have incredible power. Between their _________, readers can be transported to anywhere imaginable and become just about anyone or anything. _________ , many children all over the world don’t have access to books.

For several years now, Maria Keller, a teenager from Minneapolis, Minnesota, has been trying to _________ that fact.

When she was 8 years old, Maria already loved reading. She also noticed that some of her classmates didn’t read as much as she did. When she asked her mother why that was, her mother said that they might not be able to _________ books. Maria had never thought of this. She could not _________ that some children didn’t have bedtime stories read to them, and she became _________ to change this.

With her mother’s help, Maria _________ Read Indeed, which is a non-profit organization dedicated to collecting and distributing books to children _________.

During the early stages of Read Indeed, Maria set the _________ of collecting and distributing 1 million books by the time she was 19.

It didn’t take long to __________ that goal—to date, she has collected over 2.4 million books and has __________ them to many states and countries around the world.

She said, “I can not live without books. As I continue my mission, I have learned that the number of kids who have no books is in the hundreds of millions. So I just can’t __________ , even after reaching my __________ goal of 1 million books.”

She recently set a new goal: to __________ donations to kids in need in every state in the US and every country in the world. She keeps track of her __________ on a large map at the warehouse where her books are stored and sorted.

3 . My elder brother Steve, in the absence of my father who died when I was six, gave me important lessons in values that helped me grow into an adult. For instance, Steve taught me to face the results of my behavior. Once when I returned in tears from a Saturday baseball game, it was Steve who took the time to ask me what happened. When I explained that my baseball had soared through Mrs. Holt’s basement window, breaking the glass with a crash, Steve encouraged me to confess (认罪) to her. After all, I should have been playing in the park down Fifth Street and not in the path between buildings. Although my knees knocked as I explained to Mrs. Holt, I offered to pay for the window from my pocket money if she would return my ball. I also learned from Steve that personal property is a sacred (神圣的) thing. After I found a shiny silver pen in my fifth-grade classroom, I wanted to keep it, but Steve explained that it might be important to someone else in spite of the fact that it had little value. He reminded me of how much I’d hate to lose to someone else the small dog my father carved from a piece of cheap wood. I returned the pen to my teacher, Mrs. Davids, and still remembered the smell of her perfume as she patted me on my shoulder. Yet of all the instructions Steve gave me, his respect for life is the most vivid in my mind. When I was twelve I killed an old brown sparrow in the yard with a BB gun. Excited with my accuracy, I screamed to Steve to come from the house to take a look. I shall never forget the way he stood for a long moment and stared at the bird on the ground. Then in a dead, quiet voice, he asked, “Did it hurt you first, Mark?” I didn’t know what to answer. He continued with his eyes firm, “The only time you should even think of hurting a living thing is if it hurts you first. And then you think a long, long time.” I really felt terrible then, but that moment stands out as the most important lesson my brother taught me.

7 . There are two types of people in the world. Although they have equal degree of health, wealth and other comforts of life, one becomes happy and the other becomes unhappy. This arises from the different ways in which they consider things, persons, events and the resulting effects upon their minds.

People who are to be happy fix their attention on the convenience of things: the pleasant parts of conversation, the well prepared dishes, the goodness of the wine and the fine weather. They enjoy all the cheerful things. Those who are to be unhappy think and speak only of the opposite things. Therefore, they are continually dissatisfied. By their remarks, they sour the pleasure of society, offend many people, and make themselves disagreeable everywhere. If this turn of mind was founded in nature, such unhappy persons would be the more to be pitied. The intention of criticizing and being disliked is perhaps taken up by imitation. It grows into n habit, unknown to its possessors. The habit may be strong, but it may be cured when those who have it realize it had effects on their interests and tastes. I hope this little warning may be of service to them, and help them change this habit.

Although in fact it is chiefly an act of the imagination, it has serious results in life since it brings on deep sorrow and bad luck. Those people offend many others; nobody loves them, and no one treats them with more than the most common politeness and respect. This frequently puts them in bad temper and draws them into arguments. If they aim at getting some advantages in social position, or fortune, nobody wishes them success. Nor will anyone start, step or speak a word to favor their hopes. If they bring on themselves public objections, no one will defend or excuse them, and many will join to criticize their wrong doings. These should change this bad habit and be pleased with what is pleasing, without worrying needlessly about themselves and others. If they do not, it will be good for others to avoid any contact with them. Otherwise, it can be disagreeable and sometimes very inconvenient, especially when one becomes mixed up in their quarrels.

8 . Students are sitting in a classroom at P.S.54, a public elementary school in Brooklyn, New York. When their teacher, Adrienne Heim, strikes a bell, they take a deep breath.

The kids are practicing mindfulness. That means they are learning to pay attention to the present moment. Why?

Being mindful can help people stay calm and focused, according to Heim. She is the founder of Green Generations. The organization brings mindfulness classes to eight schools in New York City.

Isafye Lewis, 10, has been taking in the class at P.S.54 for two years. "Mindfulness teaches me to relax, " he told TFK. "It really helps me feel better when I'm sad or angry."

At P.S.54, students practice mindfulness through deep breathing, movement, and relaxation exercises. But Heim says that mindfulness is about more than just staying calm. It also boosts confidence. "It helps children have a right attitude, " She says, "so they can make healthy decisions."

Recent research published in Developmental Psychology supports this view. The study also found that mindfulness training can help kids succeed in school. That's because it trains the brain to pay attention and manage stress.

"It doesn't solve math equations for kids," Mariam Gates, author of This Moment Is Your Life, told TFK. "But what mindfulness does for all of us is help us focus on the moment we're in, which is the only place we can learn, change, or grow."

But you don't have to be in a classroom to practice mindfulness. Gates says, "You can always bring your attention to this moment and change how you experience it."

9 . Those with closed minds refused to consider any contradictory facts, and they proceed with their planned course of action, full speed ahead, with their “minds made up” and tightly shut. As an illustration, consider the situation in 1986, prior to the space shuttle Challenger’s disatrous launch that killed all seven astronauts aboard, there was a heated telephone debate between two engineers from the company that produced the shuttle booster rockets and the top officials of NASA (the federal government’s space agency). The engineers insisted that the flight was too risky because of freezing temperature at the Florida launch site. They explained that some of the seals on the fuel tanks were not designed to withstand such low temperatures and might leak under pressure, thus endangering the craft and crew.

Despite the pleas to stop the flight, officials at NASA overruled the engineers, who were best qualified to make judgments about the complex technical problems of space flight. What caused the officials to ignore the engineers? Several flights had already been postponed, and it would not look good to postpone another. It would be bad public relations to disappoint the crowds of people and news reporters waiting for the launch. Top government officials were ready to appear on the national television and take the credit for another safe flight. As a result, with their minds absolutely closed to the facts presented by the engineers, NASA officials ordered the Challenger to take off. Seventy-three seconds later, the spacecraft was enveloped in flame.

Incredibly, seventeen years later, the lesson of the Challenger disaster was repeated. In 2003, the space shuttle Columbia broke apart while re-entering the earth’s atmosphere, killing another crew of seven. During the shuttle’s liftoff, a piece of foam insulation(泡沫隔热材料) had broken off, hitting the shuttle's wing at five hundred miles per hour. Lower-level engineers at NASA begged for photographs of the Columbia in orbit, which might have shown the extent of the damage, but their closed-minded superiors ignored their requests. It was the damage caused by the 1.7 pound chunk of insulation that doomed the Columbia.

There is no virtue in ignoring contradictory facts and “sticking to your guns” when the course taken shows all the signs of being the wrong one. Closed minds are especially noticeable in political campaigns and debates. Many people line up to support one candidate or another and won’t listen to any facts presented by the opposing candidate.

All those with an open mind say is this: “I don’t know everything, so I’d better keep my mind, eyes, and ears open to any new facts that may come along.” The world would be a much better and safer place if everyone had this attitude.

10 . Our first year in New York we rented a small apartment with a Catholic school nearby, taught by the Sister of Charity, strong women in long black gowns and bats. I liked them a lot, especially my grandmotherly fourth grade teacher，Sister Zoe. I had a lovely name, she said, and she had me teach the whole class how to pronounce it: Yo-lan-da. As the only immigrant in my class, I was put in a special seat in the first row by the window, apart from the other children so that Sister Zoe could tutor me without disturbing them. Slowly, she enunciated(发音) the new words for me to repeat: cornflakes, subway, snow.

Soon I picked up enough English to understand a horrible wars was in the air. Sister Zoe explained to us that Russian missiles(导弹) were being collected and brought together, aimed supposedly on New York City.On the television. President Kennedy, looking worried too, was in the television at home, explaining we might have to go to war against the enemies. At school, we had air-raid drills: a worrying bell would go off and we’d move into the hall, fall to the floor, and shelter our heads with our coats. And at home, Mom and I prayed for world peace. I heard new vocabulary: nuclear bomb, radioactive fallout(放射性沉降物), bomb shelter. Sister Zoe explained how it would happen. She drew on the blackboard a picture of a mushroom and a cloud of dusty fallout that would kill us all.

The months grew cold, November, December. It was dark when I got up in the morning, and frosty when I followed my breath to school. One morning, as I sat at my desk daydreaming, out the window, I saw dots in the air like the ones Sister Zoe had drawn—random at first, then lots and lots. I screamed, “Bomb！Bomb！” Sister Zoe hurried to me. A few girls began to cry.

But then Sister Zoe’s shocked look disappeared. “Why, Yolanda dear, that’s snow!” She laughed. “Snow.”“Snow，” I repeated. I looked out the window cautiously. All my life I had heard about the white snow that fell out of American skies in the winter. From my desk I watched the fine-powder dust the sidewalk and parked cars below.“Each flake(雪花) was different，”Sister Zoe had said，“like a person，irreplaceable and beautiful.”
