參考解答(AI 生成,非官方)
- 一、Elon Musk is a South African-born American entrepreneur and one of the world's wealthiest people. He co-founded PayPal and is best known as CEO of Tesla, the electric-vehicle maker, and founder of SpaceX, which develops reusable rockets and the Starlink satellite network. He also owns the social media platform X, formerly Twitter, and leads Neuralink and The Boring Company. Musk is admired for pushing technological boundaries but criticized for provocative remarks and his management style.
- 二、Papua New Guinea is an independent country in the southwestern Pacific, occupying the eastern half of the island of New Guinea and hundreds of nearby islands. Its capital is Port Moresby. It is one of the world's most linguistically and culturally diverse countries, with more than 800 languages. The economy depends heavily on minerals, oil, natural gas and agriculture, while development is constrained by rugged terrain, weak infrastructure and social challenges.
- 三、3D printing, or additive manufacturing, is a process that creates a three-dimensional object by building it up layer by layer from a digital design. It can use plastics, resins, metals, ceramics and even biological materials. It enables rapid prototyping, customized medical implants, spare parts and complex geometries that traditional manufacturing cannot easily produce. Its limitations include slow mass production, high material costs, size constraints and variable quality.
- 四、Volodymyr Zelenskyy is the president of Ukraine. A former comedian and actor, he won the 2019 presidential election on an anti-corruption, reformist platform. After Russia's full-scale invasion in February 2022, he became an internationally visible wartime leader, rallying domestic morale and appealing to foreign governments and parliaments for military, financial and humanitarian support. His leadership has been widely praised, though his governance and reform record remain debated.
- 五、The ozone layer is a region of the stratosphere, roughly 15 to 35 kilometers above Earth, where ozone gas is relatively concentrated. It absorbs most of the sun's harmful ultraviolet radiation, especially UV-B and UV-C, protecting humans, animals and plants. It was damaged by chlorofluorocarbons (CFCs) and other ozone-depleting substances, but the 1987 Montreal Protocol and its amendments have led to gradual recovery.
- 六、A hurricane is a powerful tropical cyclone that forms over warm ocean waters, typically in the North Atlantic, Caribbean, Gulf of Mexico or eastern North Pacific. It has a low-pressure center, strong rotating winds of at least 74 miles per hour, heavy rain and storm surge. Hurricanes are classified from Category 1 to 5 on the Saffir-Simpson scale and can cause catastrophic coastal flooding, wind damage and loss of life. The same type of storm is called a typhoon in the northwest Pacific and a cyclone in the Indian Ocean.
