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 X­ray 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.

C．He was referred to as a founder of modern physics. D．He made important achievements in the field of electrochemistry. 解析：选D。细节理解题。根据Jöns Jacob Berzelius标题下的“Berzelius also made important discoveries in the field of electrochemistry”可知，他在电化学方面做出了重要发现。故选D。 √ 2．Who was born in Ireland? A．Jöns Jacob Berzelius. B．Niels Henrik David Bohr. C．Robert Boyle. D．William Lawrence Bragg. 解析：选C。细节理解题。根据Robert Boyle标题下的“Robert Boyle, born in Ireland”可知，罗伯特·波义耳出生在爱尔兰。故选C。 √ 3．What do Niels Henrik David Bohr and William Lawrence Bragg have in common? A．They were born in Denmark. B．They made contributions to physics. C．They discovered new models for chemistry. D．They did research together with their family. √ 解析：选B。细节理解题。根据Niels Henrik David Bohr标题下的“His model helped explain the spectra of elements and laid the groundwork for further developments in atomic physics.”和最后一段William Lawrence Bragg标题下的“William Lawrence Bragg was a British physicist born in Australia who made significant contributions to X­ray crystallography (晶体学).”可知，他们都对物理做出了贡献。故选B。 B (2024·浙江省宁波市高二上月考)People have grown taller over the last century, with South Korean women shooting up by more than 20 cm on average, and Iranian men gaining 16.5 cm.A global study looked at the average height of 18­year­olds in 200 countries between 1914 and 2014. The results show that while Swedes were the tallest people in the world in 1914, Dutch men have risen from 12th place to the top spot with an average height of 182.5 cm.Latvian women, meanwhile, rose from 28th place in 1914 to become the tallest in the world a century later, with an average height of 169.8 cm. James Bentham, a co­author of the research from Imperial College, London, says the global trend is likely to be due to improvements in nutrition and healthcare.“An individual's genetics has a big influence on their height, but once you average over whole populations, genetics plays a less key role，” he added. A little extra height brings a number of advantages says Elio Riboli of Imperial College.“Being taller is associated with longer life expectancy，” he said.“This is largely due to a lower risk of dying of cardiovascular (心血管的) disease among taller people.” But while height has increased around the world, the trend in many African countries causes concern, says Riboli.While height increased in Uganda and Niger during the early 20th century, the trend has reversed (反转) in recent years, with height decreasing among 18­year­olds. “One reason for these decreases in height is the economic situation in the 1980s，” said Alexander Moradi of the University of Sussex.The nutritional and health crises led to many children and teenagers failing to reach their potential height. James Bentham, a co­author of the research from Imperial College, believes the global trend of increasing height is of great importance.“How tall we are now is strongly influenced by the environment we grew up in，” he said.“If we give children the best possible start in life now, they will be healthier and more productive for decades to come.” [语篇解读]本文是一篇说明文，主要讲的是根据调查研究，在过去的一个世纪里，世界上的人都长高了。 4．What does the global study tell us about people's height in the last hundred years? A.There is a remarkable difference across continents. B. There has been a marked increase in most countries. C. The increase in people's height has been quickening. D. The increase in women's height is bigger than in men's. 解析：选B。细节理解题。根据第一段的“People have grown taller over the last century, with South Korean women shooting up by more than 20 cm on average, and Iranian men gaining 16.5 cm.”可知，全球研究告诉我们，在大多数国家人们的身高都有显著增长。故选B。 √ 5．What does James Bentham say about genetics in the increase of people's height? A．It counts less than generally thought. B．It outweighs nutrition and healthcare. C．It impacts more on an individual than on population. D．It plays a more significant role in females than in males. √ 解析：选C。细节理解题。根据第三段的“James Bentham...says the global trend is likely to be due to improvements in nutrition and healthcare.‘An individual's genetics has a big influence on their height, but once you average over whole populations, genetics plays a less key role，’ he added.”可知，James Bentham认为基因引起的身高增长对个人的影响大于对群体的影响。故选C。 6．What do we learn about 18­year­olds in Uganda and Niger? A．They grow up slower than their peers in other countries. B．They are actually shorter than their earlier generations. C．They find it hard to bring their potential into full play. D．They have experienced many changes of government. √ 解析：选B。细节理解题。根据第五段的“While height increased in Uganda and Niger during the early 20th century, the trend has reversed(反转) in recent years, with height decreasing among 18­year­olds.”可知，在乌干达和尼日尔，18岁的青少年实际上比他们的前几代人矮。故选B。 Ⅱ.阅读七选五(每小题2.5分，共12.5分) (2025·浙江省强基联盟高二上联考) The Happiest Diet Does what you eat affect your mood?

Prof.Jane Greaves from Cardiff University, UK, together with other scientists, 4 (try) to solve this mystery at present.They have published a paper 5 (outline) their findings and done some work 6 (determine) the gas doesn't originate from life.Despite their efforts, they have not yet reached a conclusion. No one has yet been able to say how the gas can be there without living things to create it.“I have devoted my entire career 7 searching for extraterrestrial (地球外的) life，” said Prof.Greaves, “so 8 idea that we might have found a sign of life on Venus is exciting.But we are encouraging others to contribute their ideas and help us identify 9 we may have missed.” The scientists are also investigating the possibility that the gas could be a byproduct of geological processes, but further research is needed to confirm this.10 the mystery remains unsolved, the discovery of this gas has sparked renewed interest in the search for extraterrestrial life. [语篇解读]本文是一篇说明文。文章讲述了科学家在金星或其云层中发现了神秘气体，这种气体通常与生命相关。英国卡迪夫大学简·格雷夫斯教授等科学家正研究此谜，但尚未得出结论。 1．解析：explanation。 考查名词。句意：他们在那儿发现了一种神秘的气体，但却未能给出解释。空处需填名词explanation，作宾语，不定冠词an修饰单数可数名词。故填explanation。 2．解析：which。 考查定语从句。句意：这种气体在生命存在的地方很常见，但也可以在工厂生产出来。空处引导非限制性定语从句，先行词This gas，指物，在定语从句中作主语，需用关系代词which引导。故填which。 3．解析：be produced。考查被动语态。句意同上。This gas和produce为被动关系，需用被动语态，位于情态动词can后面，使用动词原形。故填be produced。 4．解析：is trying。考查动词时态和主谓一致。句意：英国卡迪夫大学的简·格雷夫斯教授与其他科学家一道，目前正在努力解开这一谜团。根据时间状语at present可知，此处表示现阶段正在做的事情，使用现在进行时，主语有together with连接，谓语动词遵循就远原则，与Prof.Jane Greaves保持一致，be动词用is。故填is trying。 5．解析：outlining。考查非谓语动词。句意：他们发表了一篇论文，概述了他们的发现，并做了一些工作来进一步确认这种气体并非源自生命。空处需填非谓语动词作定语，a paper和outline构成逻辑上的主谓关系，需用现在分词形式。故填outlining。 6．解析：to determine。考查非谓语动词。句意同上。此处作目的状语，需用动词不定式。故填to determine。 7．解析：to。考查介词。句意：格雷夫斯教授说：“我整个职业生涯都致力于寻找外星生命，所以，我们可能在金星上发现了生命迹象的想法令人兴奋。”devote...to...为固定搭配，意为“致力于”。故填to。 8．解析：the。考查冠词。此处对idea进行特指，需用定冠词the修饰。故填the。 9．解析：what。考查宾语从句。句意：但我们鼓励其他人提出他们的想法，帮助我们找出我们可能遗漏的东西。空处引导宾语从句，从句缺少宾语，指物，需用连接代词what引导。故填what。 10．解析： Although/Though/While。考查状语从句。句意：尽管这一谜团尚未解开，但这种气体的发现再次激发了人们对寻找外星生命的兴趣。表示“尽管”应用although/though/while引导让步状语从句，位于句首，首字母需大写。故填Although/Though/While。 $
