2 . 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.

3 . Steve was a seventh grader, a big boy, looking more like a teenager than a 12-year-old. Yet, he went unnoticed — he had been________ every examination since first grade — until Miss Wilma.

In the middle of the first semester of school, the entire seventh grade was________ for basic skills.

“You all did pretty well,” Miss Wilma told the class after going over the________ except for one boy. And it________ my heart to tell you this, but…” she________ , “the smartest boy in the seventh grade is failing my class.” Steve________ his eyes and carefully examined his fingertips.

After that, Steve still wouldn’t do his homework. Even if Miss Wilma________ punished him, he remained________ .     

“Steve, please! I care about you!”________ , Steve got it! “Someone CARES ABOUT ME?!”

One Monday a couple of weeks later, Miss Wilma gave a________ on the weekend homework. Steve________ through the test and was the first to hand in his paper. With a look of________ , Miss Wilma took his paper and began to look it over.

Miss Wilma’s face was in________ shock! She glanced up at Steve, then________ , then up. The smartest boy in the seventh grade had just passed his first test!

From that moment, nothing was the same for Steve. He discovered that not only could he remember and understand________ , but he could translate what he learned into his life. He became________ . After high school, Steve enlisted in the Navy, and he had a(n)________military career. During his naval years, he inspired many young people who might not have________ themselves without him. A________ took place within the heart of a boy all because of one teacher, who________ .

5 . How often one hears children wishing they were grown up, and old people wishing they were young again. Each age has its pleasures and its pains, and the happiest person is the one who enjoys what each age gives him without wasting his time in useless regrets.

Childhood is a time when there are few responsibilities to make life difficult. If a child has good parents, he is fed, looked after and loved, whatever he may do. It is impossible that he will ever again in his life be given so much without having to do anything in return. In addition, life is always presenting new things to the child — things that have lost their interest for older people because they are too well-known. But a child has his parents, he is not so free to do what he wishes to do; he is continually being told not to do things or being punished for what he has done wrong.

When the young man starts to earn his own living, he can no longer expect others to pay for his food, his clothes, and his room, but has to work if he wants to live comfortably. If he spends most of his time playing about in the way that he used to as a child, he will go hungry. And if he breaks the laws of society as he used to break the laws of his parents, he may go to prison. If, however, he works hard, keeps out of trouble and has good health, he can have the great happiness of building up for himself his own position in society.

9 . Exercise and I had never had a good relationship due to my fear of sports. From a young age, my dad _______ me into a dozen sports. I didn’t like any of them, _______.

When I entered the University of Regina, my dad _______ telling me “You have to find a way to stay _______.” or “You don’t want to get the Freshman 15, do you?” So I _______ to give swimming a shot, but I _______ managed to go to the pool twice during the fall semester (学期). Worse still, I was _______ to convince myself that’s OK.

The spring semester came. A friend of mine _______ me if I wanted to try Zumba (尊巴) with her. All I knew about Zumba was that it was basically a kind of exercise: dancing to Latin pop songs. It didn’t sound too bad, but I couldn’t be _______.

I went, and that was it. Zumba became my ________ of tea. The instructor would always say, “Don’t worry about the steps. Have fun. Do your own thing.” That removed my ________ of sports. I didn’t have to be ________. I didn’t even have to be good. I just needed to ________ the music and move. Zumba did ________ me from the Freshman 15, and it also did so much more. It let me make ________ with my unpleasant past about physical exercise, and enjoy staying healthy.

10 . A major new facility to pull CO₂ out of the atmosphere has started operating in Iceland, which is a boost to an emerging technology that experts say could eventually play an important role in reducing greenhouse gases.

The plant in southwest Iceland is the biggest of its kind, its builder says. It is able to capture 900 tons of CO₂ every year but it needs heat and electricity to work. It is using energy produced from waste and is built on the roof of a waste incineration plant, and through the burning of rubbish, energy is generated.

Human-sized fans are built into a series of boxes. They take CO₂ out of the air, catching it in spongelike filters (过滤器). The filters are blasted with heat, freeing the gas, which is then mixed with water and pumped deep into deep underground basalt caves, where over time it turns into dark-gray stone. Pumping CO₂ into the ground is just one way to deal with it. The makers are also selling the gas to be used again. The CO₂ can be captured just a few 100 miles away. It is pumped through an underground pipeline directly into a greenhouse. Vegetables and plants love CO₂ and higher concentrations of the gas within the greenhouse improve the growth of plants.

By 2050, humanity will need to pull nearly a billion metric tons of CO₂ from the atmosphere every year through direct air capture technology to achieve carbon neutral goals, according to International Energy Agency recommendations. The plant in Iceland will be able to capture 4000 metric tons annually — just a small amount of what will be necessary, but an engineer in Climeworks, the company that built it, says it can grow rapidly as efficiency improves and costs decrease.

“This is a market that does not yet exist, but a market that urgently needs to be built,” said Christoph Gebald who co-founded Climeworks. “This plant that we have here is really the blueprint to further increase the size and really industrialize.”
