However,the idea for his most important invention came when he was doing voluntary work in the hospital.“I saw how much the patients were suffering,how much help they needed,and how hard the nurses were working,” Stewart told The Guardian.He realized that touching something after someone else is risky because that’s how many germs(病菌) spread. Driven by this idea,Stewart developed a self-sanitizing(自动消毒的) door handle that uses UV light(紫外线).It kills 99.9 percent of germs but is still safe for people and animals.The invention could be very useful for stopping the spread of disease in places like hospitals. As the tech industry in the Caribbean grows,Stewart has become a local hero.“We’re very proud of him,” said a professor from the University of the West Indies.His invention has also inspired other young people.As the co-founder of a tech platform noted,more and more young people now want to take on big challenges.They see what’s happening around the world and want to be part of it.They are eager to solve problems that affect the whole world. Stewart’s journey from a farmer to a businessman shows that a person’s background doesn’t matter.Everyone can make the world a better place. 1.What inspired Stewart to invent the self-sanitizing door handle? A.His study at the university. B.His experience in the hospital. C.His interest in new 3D software. D.His grandmother’s encouragement. 2.What is the main advantage of Stewart’s door handle? A.It works without electricity. B.It uses 3D fitting technology. C.It kills germs effectively and safely. D.It reduces nurses’ work significantly. 3.What impact has Stewart’s achievement had? A.It made the Caribbean a global technology leader. B.It broadened young people’s views in his hometown. C.It stopped germs from spreading in hospitals worldwide. D.It encouraged the Caribbean youth to solve global problems. 4.Which is the best title for the text? A.How to Stop Germs from Spreading in Hospitals B.From Poverty to Pioneer:An Inventor’s Journey C.The History of Self-Sanitizing Door Handles D.Caribbean’s Big Role in Helping Stewart B (2026浙江宁波六校高二期中) Fashion designers have a big say in what’s considered beautiful.They pick who’s in their shows and ads,shaping what’s celebrated as beauty.But this power also means responsibility—it can be used to leave people out or lift them up. When I was young,fashion was my world.I pored over various fashion magazines at my local bookstore,desiring to be tall,thin,and have long,shiny hair to fit the ideal.I wanted to be like those models,so I stopped eating.It was a tough time;my eating disorder consumed me.It took years to break free from its control,allowing me to focus on my true passions.  For so long,the fashion industry has worked hard to set an ideal of beauty that celebrates thin,young,white,and able-bodied models as the ideal.It’s impossible not to be exposed to images of models that have been photoshopped to where there’s not a single spot in sight.This idea is everywhere,and it hurts people.Shockingly,around 91% of women are unhappy with their appearance.It’s sad that teens grow up in a society where they deny themselves. There’s progress—models and musicians promote body positivity.However,the pressure to meet unrealistic standards remains.Changing these standards involves bravely celebrating diverse beauty.True inclusivity goes beyond appearances.It requires diverse decision-makers,photographers,and casting directors cooperating.Young designers often overlook this crucial aspect.Hiring plus-size or transgender photographers,diverse casting directors,or makeup artists who understand the importance of accommodating to various skin tones,is vital for an overall approach. We aimed to redefine the “bikini body” standards.However,the goal isn’t for the consumer’s body to change but for clothes to accommodate all sizes.We need more fashion for everyone,no matter their size or where they shop.It’s our responsibility as designers to challenge this narrow beauty definition.My hope is for future teens to escape the pressures I faced,developing a fashion industry celebrating diverse identities. 5.What does the underlined phrase “pored over” in paragraph 2 probably mean? A.Classified carefully. B.Read attentively. C.Compared thoroughly. D.Recommended sincerely. 6.What is the impact of the initial beauty ideals set by the fashion industry? A.Causing self-denial. B.Generating individuality. C.Focusing on true passions. D.Contributing to self-confidence. 7.What can be inferred about true inclusivity? A.It encourages personal effort. B.It satisfies traditional standards. C.It focuses on physical appearances. D.It calls for diversity and cooperation. 8.Which of the following will the author probably agree with? A.Customers will change their body shapes. B.Future teens will redefine fashion standards. C.Fashion should celebrate everyone’s uniqueness. D.“Bikini body” standards should be strengthened. 知识积累卡 一、重点单词 1.passion n.　　　　　　　  2.co-founder n.　　　　　　　　　  3.shockingly adv.　　　　　　　　　  4.deny v.　　　　　　　  5.accommodate v.　　　　  二、熟词生义 1.matter　本文义:v.　　　　　　  其他义:n.　　　　　　　  2.consume　本文义:v.　　　　　　　　　  其他义:v.　　　　　　　  三、词块速记 1.take on big challenges 　　　　　　　　　  2.have a big say 　　　　　　　　　　　  3.leave sb. out 　　　　　　　　　　　  4.lift sb. up 　　　　　　　　　　　  5.break free from its control 　　　　　　　　　　　　　　　  四、长难句分析 It’s impossible not to be exposed to images of models that have been photoshopped to where there’s not a single spot in sight. 分析:本句为主从复合句。that引导　　　　　从句,修饰先行词models;where引导　　　　　从句。  句意:　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　 参考答案 Ⅰ.1.boundaries　2.tackled　3.miracle　4.clinic　5.ward 6.outbreak Ⅱ.1.with　2.relief　3.Tragically　4.infectious　5.devotion 6.collaboration Ⅲ.1.It has been more than five decades since　2.does cause harm to readers’ eyesight 3.varying from singing,dancing to reciting poems Ⅳ.Activity 1 1.rushed forward to assist　2.every second was vital 3.With great devotion　4.relieved the panicked onlookers 5.have been put at risk　6.showing the power of simple kindness Activity 2 In the city square,an elderly man suddenly collapsed.Without a second thought,Lucy rushed forward to assist.She knew every second was vital as the crowd gathered.With great devotion,she started performing CPR,ignoring the chaos around her.Her actions not only relieved the panicked onlookers but also gave the old man a fighting chance.If she hadn’t stepped in,the man’s life would surely have been put at risk.In that moment,Lucy became a beacon of hope,showing the power of simple kindness. Ⅴ.【语篇解读】本文是一篇记叙文。文章讲述了牙买加发明家斯图尔特从贫困农家子弟成长为科技先锋的故事。他在大学发明了3D试衣软件,又在医院工作期间灵感迸发,发明了可自动消毒的门把手,为解决医院卫生问题作出贡献,激励了家乡青年勇于创新。 1.B　细节理解题。根据文章第二段可知,是他在医院的经历启发他发明了自动消毒的门把手。故选B项。 2.C　细节理解题。根据文章第三段中的“Driven by this idea,Stewart developed a self-sanitizing door handle that uses UV light.It kills 99.9 percent of germs but is still safe for people and animals.”可知,斯图尔特的门把手的主要优点是它能有效且安全地杀死病菌。故选C项。 3.D　细节理解题。根据文章第四段可知,受到斯图尔特的成就的鼓励,越来越多的加勒比地区的年轻人想要接受重大挑战,去解决全球问题。故选D项。 4.B　主旨大意题。通读全文,文章第一段介绍了斯图尔特成长于贫穷的农业社区,是家族里第一个上大学的人,还开发了3D软件;第二段讲述他在医院做志愿工作时获得发明自动消毒门把手的灵感;第三段介绍他发明的自动消毒门把手的特点;第四段说明他的成就对当地年轻人和科技产业的影响;最后一段点出他的经历证明一个人的背景不重要,每个人都能让世界变得更美好。因此整体文章围绕他从贫穷出身到成为发明家的历程展开。故选B项。 【语篇解读】本文是一篇议论文。文章通过对时尚标准的讨论,表达了人们应该打破传统观念,建立多样性的时尚标准的观点。 5.B　词句猜测题。根据“When I was young,fashion was my world.I pored over various fashion magazines at my local bookstore”可知,作者年轻时对时尚非常着迷, 所以在书店应该是仔细阅读各类时尚杂志,了解关于时尚的信息,“pored over”应该表示“仔细阅读”。故选B项。 6.A　细节理解题。根据第三段中的“This idea is everywhere,and it hurts people.Shockingly,around 91% of women are unhappy with their appearance.It’s sad that teens grow up in a society where they deny themselves.”可知,时尚界设立的美的标准致使多数女性不满意自己的容貌,从而否定自己。故选A项。 7.D　推理判断题。根据第四段中的“True inclusivity goes beyond appearances.It requires diverse decision-makers,photographers,and casting directors cooperating.”可知,真正的包容是要求有多样性和合作的,它呼吁不同时尚行业的从业者们进行合作。故选D项。 8.C　推理判断题。根据最后一段中的“We need more fashion for everyone,no matter their size or where they shop...My hope is for future teens to escape the pressures I faced,developing a fashion industry celebrating diverse identities.”可知,作者有可能会赞同“时尚界应该崇尚个人的独特性”。故选C项。 知识积累卡 一、1.热情,激情　2.联合创始人　3.令人震惊地　4.拒绝,否认　5.适应 二、1.重要　问题;事情　2.占据(某人的思想、精力)　消耗;消费 三、1.迎接重大挑战　2.有很大的发言权　3.把某人排除在外　4.鼓舞某人,使某人振奋　5.摆脱它的控制 四、定语　宾语 我们不可避免地会接触到那些经过修图的模特照片,照片里的她们肌肤无瑕,看不到一丝瑕疵。 学科网（北京）股份有限公司 $
