Marie Curie, born in Poland in 1867, is a pioneer in the field of radioactivity and the only person to win Nobel Prizes in two different sciences. Her journey began with a deep curiosity about the natural world, particularly the newly discovered element uranium. While studying at the University of Paris, she noticed that uranium salts emitted rays stronger than those of uranium itself, a phenomenon she termed “radioactivity”.
Curie’s research was groundbreaking but faced numerous obstacles. In the early 20th century, women in science were often dismissed, and she worked in a poorly equipped lab with little funding. Despite this, she persisted, isolating two new elements: radium and polonium. Her discovery of radium’s radioactive properties opened doors to cancer treatment, though the dangers of radiation were not yet understood. Curie herself suffered from radiation sickness due to prolonged exposure, yet she continued her work.
During World War I, Curie developed mobile X-ray units to help surgeons locate bullets in wounded soldiers, saving thousands of lives. Her dedication to science and humanity made her a global icon, though she remained humble, once refusing to patent her discoveries so they could benefit all of mankind.
Curie’s story is not just about scientific achievement; it’s a testament to curiosity and resilience. She once said, “Nothing in life is to be feared, it is only to be understood.” Her work reminds us that curiosity, coupled with courage, can overcome even the greatest challenges.
31．What did Marie Curie term the phenomenon of uranium emitting rays
A．Radioactivity. B．Radiation. C．Uranium salts. D．Polonium.
32．What obstacle did Curie face in her research
A．Lack of scientific interest. B．Gender discrimination and poor facilities.
C．Opposition from the government. D．Fear of radiation.
33．How did Curie contribute during World War I
A．By inventing new weapons. B．By developing X-ray units for field hospitals.
C．By training nurses. D．By patenting her discoveries.
34．Why did Curie refuse to patent her discoveries
A．She didn’t believe in patents. B．She wanted them to benefit everyone.
C．She forgot to apply for patents. D．Her research was incomplete.
35．What is the main message of the passage
A．Curiosity and resilience drive scientific progress. B．Women face more challenges in science.
C．Radiation is dangerous but useful. D．Nobel Prizes are important for scientists.
【答案】31．A 32．B 33．B 34．B 35．A

【导语】本文是说明文。通过介绍2024年12月29日在北京亮相的CR450高速列车的时速、技术优势、乘客舒适性设计及研发意义，展现了中国高铁的创新能力与科技实力，凸显其对中国铁路发展的重要性。
56．句意：这种列车在检测中时速可达450公里。kilometre是可数名词，前面有基数词450修饰，应用复数形式。故填kilometres。
57．句意：当它开始投入商业运营时，它将成为世界上最快的高速列车，比时速350公里的CR400快得多。此处是when引导的时间状语从句，遵循“主将从现”原则，从句主语“it”是第三人称单数，谓语动词用第三人称单数形式。故填starts。
58．句意：当它开始投入商业运营时，它将成为世界上最快的高速列车，比时速350公里的CR400快得多。根据空后“than”可知，此处应用形容词fast的比较级形式，表两者之间的速度对比。故填faster。
59．句意：尽管它的速度更快，但它的刹车性能与时速350公里的列车一样好。“speed”是可数名词单数，且“higher”是以辅音音素开头的单词，前面应用不定冠词a修饰，at a higher speed表示“以更快的速度”。故填a。
60．句意：这是因为出色的工程设计有助于列车在高速运行时保持平稳和安全。此处修饰动词“runs”，应用形容词quick的副词形式quickly。故填quickly。
61．句意：通过采用良好的降噪技术，列车内部和时速350公里的列车一样安静。根据句意可知，空后“using good noise-cutting technology”是实现“the inside of the train is as quiet...”的方式，应用介词by，表示“通过……方式”，句首首字母大写。故填By。
62．句意：此外，它的运行阻力降低了22%，重量降低了10%，这有助于节省能源。“its running resistance has been reduced...”与“its weight has been reduced...”是并列关系，应用连词and连接两个并列的分句。故填and。
63．句意：列车内部经过重新设计，空间增加了4%，还有更好的行李放置处。place是可数名词，根据空前“better”及语境可知，此处指多个行李放置处，应用复数形式。故填places。
64．句意：这两款样车由不同公司制造，但都希望为乘客提供愉快的旅程。want to do sth是固定短语，意为“想要做某事”，此处应用动词不定式to give。故填to give。
65．句意：总而言之，CR450高速列车展现了中国的创新能力及其科技实力。此处修饰名词“scientific powers”，应用形容词性物主代词its，指代“China’s”。故填its。

Marie Curie, born in Poland in 1867, is a pioneer in the field of radioactivity and the only person to win Nobel Prizes in two different sciences. Her journey began with a deep curiosity about the natural world, particularly the newly discovered element uranium. While studying at the University of Paris, she noticed that uranium salts emitted rays stronger than those of uranium itself, a phenomenon she termed “radioactivity”.
Curie’s research was groundbreaking but faced numerous obstacles. In the early 20th century, women in science were often dismissed, and she worked in a poorly equipped lab with little funding. Despite this, she persisted, isolating two new elements: radium and polonium. Her discovery of radium’s radioactive properties opened doors to cancer treatment, though the dangers of radiation were not yet understood. Curie herself suffered from radiation sickness due to prolonged exposure, yet she continued her work.
During World War I, Curie developed mobile X-ray units to help surgeons locate bullets in wounded soldiers, saving thousands of lives. Her dedication to science and humanity made her a global icon, though she remained humble, once refusing to patent her discoveries so they could benefit all of mankind.
Curie’s story is not just about scientific achievement; it’s a testament to curiosity and resilience. She once said, “Nothing in life is to be feared, it is only to be understood.” Her work reminds us that curiosity, coupled with courage, can overcome even the greatest challenges.
31．What did Marie Curie term the phenomenon of uranium emitting rays
A．Radioactivity. B．Radiation. C．Uranium salts. D．Polonium.
32．What obstacle did Curie face in her research
A．Lack of scientific interest. B．Gender discrimination and poor facilities.
C．Opposition from the government. D．Fear of radiation.
33．How did Curie contribute during World War I
A．By inventing new weapons. B．By developing X-ray units for field hospitals.
C．By training nurses. D．By patenting her discoveries.
34．Why did Curie refuse to patent her discoveries
A．She didn’t believe in patents. B．She wanted them to benefit everyone.
C．She forgot to apply for patents. D．Her research was incomplete.
35．What is the main message of the passage
A．Curiosity and resilience drive scientific progress. B．Women face more challenges in science.
C．Radiation is dangerous but useful. D．Nobel Prizes are important for scientists.

“家” 的演变
This is the word “family” written in Chinese—“家”. It's a pictographic character (象形文字) . The “宀” looks like the roof (屋顶) of a house, and the “豕” is a pictographic character for “pig” , which is developed from a picture like this:
The word “家” with a pig under the roof of a house may show the importance of domestic animals (家畜) to traditional Chinese families.

We remember our ancestors, not for any advantages for ourselves but to make our feelings more active. Whenever we think of them, they make us stronger inside.

December 29, 2024, was a wonderful moment for China’s high-speed trains. Two samples of the CR450 high-speed train were shown in Beijing on the day. This kind of train can reach a speed of 450 56 (kilometre) per hour in tests. When it 57 (start) to be put into use for business, it will be the quickest high-speed train in the world, much 58 (fast) than the CR400 that runs at 350 km/h.
The China State Railway Group, which made this train, said that the CR450 has set new global standards in many important parts like speed, using less energy, making less noise, and braking (刹车) performance. Even though it goes at 59 higher speed, its braking is as good as that of the 350 km/h trains. This is because the great engineering design helps to keep the train steady and safe even when it runs 60 (quick).
The CR450 also cares a lot about making passengers feel comfortable. 61 using good noise-cutting technology, the inside of the train is as quiet as the 350 km/h trains. What’s more, its running resistance (阻力) has been reduced by 22 percent, 62 its weight has been reduced by 10 percent, which helps to save energy. The inside has been redesigned, with 4 percent more room, and there are better 63 (place) to put baggage.
The two samples were made by different companies, but both want 64 (give) passengers a nice trip. The China State Railway Group will do more tests to make sure the train is okay for business use.
All in all, the CR450 shows China’s ability to make new things and 65 (it) scientific powers. It is also important to make a breakthrough in China’s railway growth.
