1 . Here are the introductions and achievements of four scientists.
Jöns Jacob Berzelius
Jöns Jacob Berzelius was a Swedish chemist, often referred to as one of the founders of modern chemistry. He developed a system of chemical symbols, which laid the foundation for the establishment of the modern periodic table. Berzelius also made important discoveries in the field of electrochemistry.
Niels Henrik David Bohr
Niels Henrik David Bohr was a Danish physicist. He proposed the atomic (原子的) model known as the Bohr model, which explained the behavior of electrons moving in fixed energy levels or orbits around the atomic nucleus. His model helped explain the spectra of elements and laid the groundwork for further developments in atomic physics.
Robert Boyle
Robert Boyle, born in Ireland, was regarded as one of the founders of modern chemistry, known for Boyle’s law. Boyle’s law describes the relationship between the pressure and volume (体积) of a gas at constant temperature. Boyle’s work laid the foundation for the modern understanding of gas behavior and promoted the development of scientific experimental methods.
William Lawrence Bragg
William Lawrence Bragg was a British physicist born in Australia who made significant contributions to X-ray crystallography (晶体学). Together with his father William Henry Bragg, he developed the famous Bragg’s law. This discovery revolutionized the field of crystallography and paved the way for determining the atomic and molecular structures of various substances, including DNA and proteins.

3 . As the capital city of France, Paris has endured as an important city for more than 2,000 years. Take an overview of the top tourist attractions in Paris.
Place des Vosges
The Place des Vosges, formerly called Place Royale, was the prototype (原型) for all residential squares in Europe. All houses were built, using the same design: red brick and steep pitched blues late roofs. Not only is it shaped like a true square, but also it is the first city square planned by a king (Henry Ⅳ in the early 17th century) . Third, it turned the Marais into a fashionable spot in the decades before the French Revolution.
Moulin Rouge
1889is known as the year when France’s most famous landmark, the Eiffel Tower, was constructed. It’s also the year the Moulin Rouge opened its doors as an entertainment venue. It has been the subject of numerous films for many years.
Conciergerie
The Conciergerie was built to be the main palace for French kings who, over the centuries, enlarged it. Its Great Hall was one of the largest in Europe. The palace later became a tribunal (法庭) and prison, with famous prisoners including Marie Antoinette. Today the Conciergerie is a popular tourist attraction in Paris but also still serves as courts.
Palais Garnier
Architect Charles Garnier spared no ornate (华丽的) detail when designing the Palais Garnier in the 19th century. Perhaps this is why the building was the most expensive of its era. Seating nearly 2,000 people, the Palais Garnier is home to the National Opera of Paris. It is the star of the novel and subsequent films, Phantom of the Opera. The Palais Garnier is still in use today though mainly for ballet and is also home to the opera library museum.

6 . Parents annoyed by their little ones’ picky food choices often sigh in anger, thinking, “They’ll grow out of it by college.” Maybe not, suggests a new study from Bowling Green State University in Ohio. Some young people continue their picky eating into early adulthood, often restricting their diets to 10 foods or even fewer. Such a deficient diet can mean they’re not getting the fibre and vegetables they need, which could be a health problem. They study also suggests picky eaters may also be experiencing other challenges such as social phobias (恐惧症), including around eating. The social phobia is the fear of being judged by others during everyday activities, often resulting in fear or embarrassment.
For the study, researchers surveyed 488 Midwestern college students. About 40% of the students were identified as picky eaters. And about 65% of those respondents said they ate fewer than 10 foods. “We asked participants to just tell us what challenges around picky eating might have had or any benefits they might see, and people answered differently in terms of what has an effect on them,” said co-author Lauren Dial, a doctoral student at Bowling Green State at the time of the study.
Many indicated they’d eat less or not at all outside the home. One 19-year-old man said he’d drink water half the time “due to my picky eating”, according to the study. Another 18-year-old said, “Sometimes there are some awkward comments when I am eating with my girlfriend and her family.” A 23-year-old woman said her parents would get frustrated at her refusal to try the foods she was served.
“Picky eating does have a lot to do with the presentation of foods (how they’re presented on a plate), and the texture (口感) of foods (is it a consistent texture),” Dial Said, “but there’s also fear of trying new foods and that might play into picky eating.” By learning more about picky eating in adults, the researchers said they may be able to determine how best to intervene (干预) before the problem becomes more severe for some people.

8 . A blind Chinese climber reached the summit (顶点) of Qomolangma, known in the West as Mount Everest, on Monday morning, becoming the first blind person from Asia ever to conquer the world’s highest summit.
Zhang Hong, 46, reached the top from the Nepali side, along with three high-altitude guides.
Zhang, who was born in Chongqing, lost his sight at the age of 21. He now works at Fukang Hospital Affiliated with Tibet University in Lhasa. As Zhang began his climb of Qomolangma, which is 8,848. 86 meters above sea level, his colleagues in Lhasa were excited to hear the news of his success.
“Many people may have doubted his attempt of climbing at first, but I was confident in him from the beginning,” said Kyila, the secretary of the Fukang Angel Foundation, who also is a blind person. “I knew before that he could make it, and he did make it. I am really happy for him. He is a model for blind people to encourage them to chase their dreams.”
Zhang’s passion for climbing was inspired by Lotse, a famous Tibetan climber who conquered all the world’s 14 summits above the altitude of 8,000 meters. Lotse had shared the story of the blind US mountaineer Erik Weihenmayer, who climbed Qomolangma in May 2001. Zhang was touched by the story, which ignited his dream of climbing.
As an amateur climber for years, Zhang had conquered three mountains above the altitude of 6,000 meters before climbing the world’s highest summit. He had begun preparing for the Qomolangma climb in 2019. However, due to the COVID-19 pandemic (流行病), all mountaineering teams on Qomolangma were canceled in Nepal and China last year, and he had to wait until recently to finally make the attempt.
1. What can we infer from what Kyila said?A.He had been inspired by Lotse. |
B.He had much belief in Zhang’s success. |
C.Zhang’s colleagues doubted his motivation. |
D.Zhang centered on climbing in his spare time. |
A.Lighted. | B.Accomplished. | C.Followed. | D.Recalled. |
A.He was too weak. | B.He wasn’t well prepared. |
C.A pandemic broke out. | D.Extreme weather occurred. |

10 . Born in Guangzhou in October 1936, Zhong Nanshan is one of the greatest doctors in China, as well as an academic at the Chinese Academy of Engineering. After graduating from Medical College in Beijing in 1960, he worked as a teacher.
For years as a leading Chinese specialist in respiratory (呼吸道) diseases, Zhong was well-known, but the outbreak of SARS has turned him into a household name across the country. Zhong was one of a limited number of doctors informed of the disease from the moment the first few cases were reported through the inner medical network in Guangdong. He and his colleagues had been busy fighting it for more than a month before he appeared at the press conference in Guangzhou. Under his guidance, an effective treatment method was discovered not long after, and Guangdong achieved the lowest death rate and highest recovery rate for SARS in China.
In 2010, in order to reform medical education and cultivate (培养) more medical talents, Zhong interviewed and selected students for a 32-student “Nanshan class”. Zhong worked as a headteacher. The class aimed to provide more hands-on training, student-teacher interaction and international viewpoints than the average course. Chinese medical students are often taught in big groups and seldom get the chance to perform clinical practice. “I hope that all of you can have more contact with patients from the very beginning. We should make ourselves practical and creative, not just fluent English-speakers who work as high-ranking employees in foreign laboratories,” Zhong said at the course opening ceremony.
Zhong’s working attitude left a deep impression on his colleagues. “What impresses me most is his double-tube stethoscope (听诊器). Compared with other ones, it’s much heavier, but it works more precisely, so Mr. Zhong carries it with him wherever he goes,” said Li Huiling, a post-doctorate fellow at the respiratory diseases research center in Guangzhou.

C.They found a way to treat SARS. | D.They achieved zero death rate for SARS. |
A.To train more excellent talents. | B.To interview students in person. |
C.To make students taught in groups. | D.To help students enter foreign labs. |
A.Zhong got well on with his colleagues. | B.Li Huiling impressed Zhong most. |
