As Aristotle said, no one would choose to live without friends, even if he had all other goods. 03 美文阅读润心 在人类的历史长河中，病毒曾如黑暗中的恶灵，摧毁了生命的美好。然而，英国医生约翰·斯诺如同一轮明月，照亮了人类抗击疾病的道路。他的故事是一曲传世的颂歌，描绘着勇气、智慧与拯救的壮丽画卷。通过他的不懈探索，我们找到了战胜霍乱的钥匙，开启了健康与生命的新篇章。 Cholera used to be one of the most feared diseases in the world, until a British doctor, John Snow, showed how it could be overcome.This illness causes severe diarrhoea, dehydration, and even death.In the early 19th century, when an outbreak of cholera hit Europe, millions of people died from the disease.As a young doctor, John Snow became frustrated because no one knew how to prevent or treat cholera.In time, he rose to become a famous doctor, and even attended to Queen Victoria when she gave birth.However, he never lost his desire to destroy cholera once and for all. In general, doctors in those days had two contradictory theories to explain how cholera spread.One theory was that bad air caused the disease.The other was that cholera was caused by an infection from germs in food or water.Snow subscribed to the second theory.It was correct, but he still needed proof.Consequently, when an outbreak of cholera hit London in 1854, Snow began to investigate. He discovered that in two particular streets the cholera outbreak was so severe that more than 500 people died in ten days.He was determined to find out why. ① Snow began by marking on a map the exact places where all those who died had lived.There were multiple deaths near the water pump in Broad Street (especially house numbers 16,37,38，and 40)．However, some households (such as 20 and 21 Broad Street, and 8 and 9 Cambridge Street) had had no deaths.These people worked in the pub at 7 Cambridge Street.They had been given free beer, and so had not drunk the water from the pump.Snow suspected that the water pump was to blame.What is more, in another part of London, a woman and her daughter had died of cholera after moving away from Broad Street. ② It seemed that the woman liked the water from the pump so much that she had it delivered to her house every day.As a result of this evidence, John Snow was able to announce that the pump water carried cholera germs. Accordingly，he had the handle of the pump removed so that it could not be used. Through this intervention, the disease was stopped in its tracks. ③ ④ The truth was that the water from the Broad Street pump had been infected by waste.Moreover，Snow was later able to show a link between other cases of cholera and the different water companies in London.Some companies sold water from the River Thames that was polluted by raw waste.The people who drank this water were much more likely to get cholera than those who drank pure or boiled water. Through Snow's tireless efforts, water companies began to sell clean water, and the threat of cholera around the world saw a substantial decrease.However, cholera is still a problem.Each year, millions of people around the world get cholera and many die from it.Fortunately, we now know how to prevent cholera, thanks to the work of John Snow.Moreover, in his use of maps and statistics，Snow transformed the way scientists study diseases.For this reason，Snow is considered the father of modern epidemiology. [阅读理解] 1．Which of the following theories did John Snow believe in? A．People breathed in the bad air infected by the disease. B．People absorbed cholera into their bodies with their meals. C．People got infected with cholera because of cold and hunger. D．People suffered from cholera because they were not clean. √ 2．What was the key to John Snow's discovery? A．The local British government. B．The woman living in the Broad Street. C．The company offering the water. D．The map made by himself. √ 3．What conclusion did John Snow draw according to the evidence? A．Cholera could never be killed. B．Cholera multiplied in the water. C．Polluted water carried the virus. D．The dangerous gas caused cholera. √ [素养积累] 1．由文积词汇 cholera n．　　　　 霍乱 severe adj. 极为恶劣的； 十分严重的；严厉的 frustrated adj. 懊恼的；沮丧的；失意的 infection n. 感染；传染；影响；传染病 consequently adv. 因此；所以 multiple adj. 数量多的；多种多样的 pump n. 泵；抽水机；打气筒 intervention n. 介入；出面；干涉 statistic n. 统计数字；统计资料；统计学 2．据文悟句式 句①：这是一个复合句。that in two ...ten days为宾语从句，该从句中包含so ...that ...引导的结果状语从句。 句②：本句中by marking ...lived是方式状语，where all those who died had lived 是定语从句，修饰先行词the exact places，其中又包含另一个定语从句who died，修饰先行词those。 句③：It seemed that ...表示“似乎，看起来”；had it delivered是have sth.done结构，表示“请人做某事”。 句④：本句中so that引导目的状语从句。 04 课时检测 (标 语篇配有教师讲评课件) Ⅰ.阅读理解 A Rick Guidotti put aside his career as a fashion photographer to turn his lens (镜头) to people living with genetic, physical and behavioural differences. He says what changed his perception (看法) of beauty was a chance encounter with an albino (患白化病的) girl.“I was just tired of people telling me who was beautiful.Every season that face would change but I was always told who was beautiful.As an artist, I don't see beauty just on covers of magazines.I see it everywhere.So that was my original intention — that opened my eyes a little wider and wider.” Guidotti has created Positive Exposure, a not－for－profit organization that uses photography and video to transform public perceptions and promote a world where differences are celebrated.Guidotti and Positive Exposure are featured in a new documentary called On Beauty. One of the women featured in the film is Jayne Waithera.“I never thought I was beautiful because nobody said that to me, but meeting him was my profound moment.I remember that particular day.He took my picture and I felt so good like I felt there's somebody who, like, really loves me and sees me for who I am and who sees me more than my condition.” Guidotti is travelling from city to city to promote On Beauty.He says his tour is not about money; it's about the message.“As I travel from community to community, I'm taking photographs and I'm empowering (给某人……的权力) individuals with a positive sense of who they are.They're seeing beauty in their reflection but I'm also empowering their families and they in turn are empowering their communities as well.All is based on the philosophy of change — how you see, how you change.” 语篇解读：本文是一篇记叙文。文章主要讲述了与一位白化病女孩的偶然相遇使Rick Guidotti对美的看法发生了改变，他放弃了时尚摄影师的职业生涯，将他的镜头转向那些在遗传、生理和行为方面有差异的人，并拍摄了一部名为《何为美》的纪录片来努力推动一个赞美不同和差异的世界。 1．Why did Guidotti change his career? A．The beauty on covers of magazines is not beautiful. B．He wanted to create his own company. C．His comprehension of beauty changed owing to an albino girl. D．He couldn't earn enough money from his former career. 解析：细节理解题。根据第一段以及第二段中的“He says what changed his perception of beauty was a chance encounter with an albino girl.”可知，与白化病女孩的偶然相遇改变了他对美的看法，这件事使得他改变了自己的职业。 √ 2．What can we know about Positive Exposure? A．It welcomes differences in the world. B．It brings a lot of money for Guidotti. C．It makes photography more popular. D．It makes the public more beautiful. 解析：细节理解题。根据第三段中的“Guidotti has created Positive Exposure ... where differences are celebrated.”可知，Positive Exposure是一个非营利性组织，通过摄影和视频促进一个尊重差异的世界。 √ 3．What does the author want to tell us by mentioning Jayne in paragraph 4? A．Jayne's picture was more beautiful than herself. B．Jayne was beautiful indeed. C．Photographs gave Jayne a positive sense of who she was. D．It was unfair that nobody discovered Jayne's beauty. √ 解析：推理判断题。根据第四段中的“I never thought I was beautiful ... and who sees me more than my condition.”可知，这张照片让Jayne Waithera看到了真实的自己，使得Jayne Waithera对自己有了正面的认识。 4．What does the author mainly intend to tell us in the last paragraph? A．Communities have a great influence on everyone. B．We should travel frequently. C．Your attitude to seeing the world decides your behaviour. D．We should make contributions to our community. 解析：推理判断题。根据最后一段中的“All is based on the philosophy of change — how you see, how you change.”可知，作者想通过这一段告诉读者，你看待世界的态度决定了你的行为。 √ B The 2024 Nobel Prize in chemistry honored a real－world example of how AI is helping humans today with astonishing discoveries in protein structure that have far－reaching applications.This is a development worth savoring (品味)． Proteins are biology's lead actors.As the Nobel Committee pointed out, proteins “control and drive all the chemical reactions that together are the basis of life”．In the human body, they are necessary for the structure, function and regulation of tissues and organs.At the end of the 1950s, University of Cambridge researchers John Kendrew and Max Perutz successfully used a method called X－ray crystallography to produce the first 3D models of proteins.In the following half－century, the search for documenting protein structures remained ___________. laborious The 2024 Nobel Prize in chemistry went to three scientists who revolutionized the field.David Baker of the University of Washington built entirely new kinds of proteins.Demis Hassabis and John Jumper developed an AI and machine learning model that can predict the structure of proteins, decoding (解码) the amino acids (氨基酸) that make up each.The model, AlphaFold, can do in minutes what once took years to overcome. AlphaFold takes advantage of neural networks that can locate patterns in enormous amounts of data.The system was trained on the vast information in the databases of all known protein structures and amino acid sequences.AlphaFold has predicted more than 200 million protein structures, or nearly all cataloged proteins known to science.To design new drugs and vaccines, scientists need to know how a protein looks or behaves.The AlphaFold result is just a prediction — a visual representation of a protein's expected structure — but such predictions can accelerate biomedical research. Anyone knows that AI is not always correct.But AI will only get better over time.Already, the AlphaFold effort is expanding to create accurate visualizations of how proteins interact with other biomedical structures.For now, AlphaFold shows that AI can supercharge existing knowledge to benefit mankind.And there will be more to come. 语篇解读：本文是一篇新闻报道。文章主要介绍了2024年诺贝尔化学奖被授予了在蛋白质结构领域利用人工智能技术取得重大突破的三位科学家，以及这一突破对生物医学研究和人类社会的深远影响。 5．What does the underlined word “laborious” in paragraph 2 mean? A．Aimless.　　　　　　 B．Productive. C．Energy－consuming. D．Thought－provoking. √ 解析：词义猜测题。根据第三段中“The model, AlphaFold, can do in minutes what once took years to overcome.”可知，画线词所在句子表示“在接下来的半个世纪里，寻找蛋白质结构的记录仍然是艰苦的”，故画线词意为“耗时费力的”，和energy－consuming意思相近。 6．What can we learn about AlphaFold? A．It makes use of anything but the prior information. B．Its prediction can contribute to biomedical research. C．It is collective efforts of three scientists. D．Its prediction shows protein structures multi－dimensionally. √ 解析：细节理解题。根据第四段中“The AlphaFold result is just a prediction — a visual representation of a protein's expected structure — but such predictions can accelerate biomedical research.”可知，AlphaFold的预测有助于生物医学的研究。 7．What is the author's attitude towards the AI in biology? A．Cautious. B．Doubtful. C．Dismissive. D．Approving. 解析：观点态度题。根据最后一段中“For now, AlphaFold shows that AI can supercharge existing knowledge to benefit mankind.And there will be more to come.”可知，作者认为AlphaFold可以扩展应用，AI可以促进现有知识为人类造福，并且会越来越好，所以作者对生物学中的AI是持赞成态度的。 √ 8．Which of the following could be the best title for the text? A．AI: a Booster of Protein Research B．Protein: the Builder of Human Life C．AlphaFold: the Decoder of Protein Structure D．Nobel Prize: a Recorder of Protein Development 解析：标题归纳题。通读全文，尤其是第一段可知，本文主要讲了2024年诺贝尔化学奖被授予了在蛋白质结构领域利用人工智能技术取得重大突破的三位科学家，以及这一突破对生物医学研究和人类社会的深远影响，故A项(人工智能：蛋白质研究的助推器)适合作为标题。 √ Ⅱ.阅读七选五( ) Traditional Chinese Medicine, or TCM, has been around for thousands of years and integrates Taoism (a nature－based philosophy) with elements of Buddhism and Confucianism.Centered around the core belief is that qi is the essential energy that flows through our bodies and powers all human life. 9 . The first suggests that everything about a person is interrelated. 10 .And they affect one another because of this interconnection. The second assumes that every person is part of the natural world, and in so being, is affected by everything from the time, the place, the season, to one's age, genetic disposition (组成), and physical condition. The third states that, like all things in nature, we are regenerative (再生的) and have the inborn ability to heal our bodies. 11 . The fourth is that prevention is the key to staying well. 12 .Do not ignore the warning signs.In this way, you can prevent a more serious condition from developing. 13 .They include herbal medicines and diet, foot reflexology (反射论) massage, tai chi, acupuncture, and acupressure (针压法) — to name a few of the more well－known ones.These methods are used to promote the unrestricted flow of qi throughout the body, which is said to promote health.They are also used to balance the opposing forces of yin and yang, believed by Taoists to be found in all things. A．TCM is based on four key principles B．The connections are unnatural enough C．Taking physical examination regularly does not work D．Listen to our bodies and making adjustments when necessary E．One's physical body, emotions, mind, and spirit are all interconnected F．Unlocking this ability is the key to regaining and maintaining good health G．To achieve and maintain good health, TCM employs a number of methods 语篇解读：本文是一篇说明文。文章主要介绍了中医的四大原则，以及为了达到和保持良好的健康，中医采用的一些方法。 9．选A　根据第五段中“The fourth is that prevention is the key to staying well.”以及每一段首句可知，接下来介绍的是中医的四个原则。故A项“中医基于四个关键原则”引出下文，符合语境。 10．选E　下文“And they affect one another because of this interconnection.”中的they指代空中的内容；此段介绍的是人体之间存在联系，人的身体各部位相互影响，故E项“一个人的身体、情感、思想和精神都相互联系”符合语境。E项中的“interconnected”对应后文中的“interconnection”，they指代E项中的“physical body, emotions, mind, and spirit”。 11．选F　根据上文“The third states that, like all things in nature, we are regenerative and have the inborn ability to heal our bodies.”可知，空处总结上文指出天生的能力可以自我治愈，故F项“释放这种能力是恢复和保持良好健康的关键”承接上文，符合语境。F项中的“this ability”对应上文“have the inborn ability”。 12．选D　根据上文“The fourth is that prevention is the key to staying well.”可知，本段主要介绍预防是关键，不要忽视身体的预警，故D项“倾听我们的身体，并在必要时做出调整”正是对身体预警的解释，符合语境。 13．选G　根据本段内容可知，该空位于句首，总领全段。下文主要说明了中医采用保持健康的各种方法，故G项“为了达到并保持身体健康，中医采用了许多方法”衔接下文，符合语境。 本课结束 更多精彩内容请登录：www.zghkt.cn $
