Role models are powerful. No matter what stage of life you’re at, it’s good to have someone who encourages you to be the best version of yourself. Recent winners of national commendations mean we have a wider range of possible role models.
As part of the celebration of the 70th anniversary of the founding of the People’s Republic of China (PRC), President Xi Jinping signed a presidential decree (主席令) on Sept 17 to award 42 people the Medal of the Republic, the Friendship Medal and national honorary titles, China Daily reported. Recipients come from various backgrounds, including scientists, lawmakers, educators, artists, model workers and six non-Chinese individuals. All have made big contributions to the nation’s construction and development.
Chinese scientist Tu Youyou is one of the eight who were awarded the Medal of the Republic. Tu, who won the 2015 Nobel Prize for her discovery of the malaria drug artemisinin (抗疟药物青蒿素), is the first Chinese citizen to win a Nobel Prize in Physiology or Medicine. She has saved millions of lives worldwide. She has also made important scientific innovation in traditional Chinese medicine.
“It is my dream that Chinese medicine will help us conquer life-threatening diseases worldwide and that people across the globe will enjoy its benefits,” Tu once wrote in the science journal Nature Medicine.
Tu is not the only one who has given her life to the country’s development. Nan Rendong, before his death in 2017, led the research and development of China’s Five-hundred-meter Aperture Spherical Telescope, the world’s largest radio telescope. He worked on the project for more than 20 years. The facility he designed helps humans search for extraterrestrial civilizations (外星文明) and marked a Chinese technological milestone. His contributions to Chinese astronomy earned him the title, “the people’s Scientist.”
Also receiving awards are six foreign friends who have lent their hands to assist with China’s prosperity. Former French Prime Minister Jean-Pierre Raffarin, an honoree of the Friendship Medal, is an advocate of the Belt and Road Initiative. Having worked to strengthen the friendship between French and Chinese people in the past decades, he told Xinhua that he is “sincerely pleased” with the honor. “To work for this friendship is to work for peace,” Raffarin said.
Thanks to the great efforts made by these heroic figures, we can live in a prosperous and peaceful country. Hopefully these role models can also light the way for future nation buildings.

The fact that your hair turns grey because of stress is nothing more than an old wives' tale. It's true that stress isn't good for you, but it's not going to turn you into a silver fox just yet. In fact, the answer comes from the cells in your hair. These are what decide the color and, eventually, the fade to grey.
Most of us start to notice our first grey hairs by the time we hit our thirties. A general rule to go by is that by the age of 50, half of the population will have lost the color in 50 percent of their hair.
But why does it happen? Firstly, we need to understand how hair gets its color.
Your hair is made up of cells called melanocytes (黑色素细胞) which produce pigments (色素) as they grow into the hair fiber. There are two different types of melanins: eumelanins and pheomelanins. The former produces black and brown pigments, while the latter produces red and yellow pigments. The exact amount of these pigments decide whether a person has black, brown, blonde or red hair.
As we age, the ability of the melanocytes to produce more pigments weakens. That's because our hair grows in different periods.
The growing period lasts between three and five years, after which our follicles (毛囊) turn off for about three months to rest and get ready to grow more hairs. This goes round and round and, after a time, our bodies aren't as good at producing new hairs.
Scientists are continuing to try and find ways to prevent greying hair. A team of scientists in France is working to try and stop the melanocytes from being damaged at the end of each hair cycle. They are trying to use a special enzyme (酶) to protect the cells from damage. If successful, it could lead the way for new products that keep our hair full of color for years to come.
1.What does the phrase ''an old wives' tale'' in Paragraph 1 probably mean?
A.A wrong belief B.A useful talk
C.A scientific rule D.A helpful experience
2.What do we know about red hair?
A.It doesn’t turn grey as people get older.
B.It contains more pheomelanins than eumelanins.
C.The amount of pigments in it doesn't change over time.
D.People with red hair have weaker ability to produce pigments.
3.What do the French scientists aim to do?
A.To repair damaged hair follicles.
B.To protect hair cells against damage.
C.To shorten the hair cycle to protect the hair.
D.To study the relationship between health and hair color.
4.What can be a suitable title for the text?
A.Grey Hair: a Symbol of Huge Pressure.
B.Grey Hair: a Symbol of Declining Health.
C.Cells: the Cause of New Hair Growth.
D.Cells:the Cause of Color Change of Hair.
Emilia Dobek traces her interest in space and the universe back to third grade when she and her father watched a blood moon — a total lunar eclipse (月食)---on the roof of their house.
Now a seven-grader at East Prairie Elementary School, Dobek recently won the national Discovery Education Beyond Challenge by designing a space station for traveling to Mars. She says that night watching the lunar eclipse launched a passion in her that has yet to run out of fuel.
So, when her teacher, Andrea Smeeton, received information about the national challenge, Smeeton said she immediately had one student in mind. “I knew she would love the challenge and that she would go way beyond in her research,” Smeeton said. “She immediately started researching bone density of astronauts and how to have sustenance on Mars.”
“My design will ensure the safety of the astronauts but also make sure their comfort is out of this world,” said Dobek. Dobck’s design calls for building the MSS or Mars Storage Station to accommodate the need for abundant supplies. She explains how her spacecraft—the Adventurer—will get into a space station before flying to the MSS to get supplies. Her design includes the SGF or SelfGrowing Farm, and she details how it would work with the elements on Mars.
Then there is physical and leisure activity for the astronauts under Dobck’s design. A. simulator (模拟器) allows astronauts to choose their exercise machine and virtual reality environment. Rooms have circular ceilings, she says, so astronauts will be able to watch downloaded shows and even see places on Earth, such as their homes. Chief among her immediate goals, she said, is to inspire with this project. want to tell other kids to follow their passions,” Dobek said. “Whatever they want to do, they should kind of just push for it. They should always try their best.”
1.What launched Dobek’s passion for space and the universe?
A.Winning the national challenge.
B.Observing the lunar eclipse with her father.
C.Studying with her teacher Andrea Smeeton.
D.Designing a space station for traveling to Mars.
2.How can astronauts entertain themselves in Dobek’s design?
A.By exercising in outer space. B.By playing virtual reality games.
C.By appreciating places on Earth. D.By enjoying shows of their homes.
3.What is Dobek’s major aim with her project?
A.To realize her immediate goals.
B.To create a leisure design for astronauts.
C.To get inspired by the national challenge.
D.To encourage others to pursue their interest.
4.What is the best title for this passage?
