The phrase “by the bootstraps”, describing those who have found success through dogged work and stubborn will, rose from The Surprising Adventures of Baron Munchausen: the aristocrat (贵族) pulls himself from a swamp - not by his bootstraps, but by his hair. And Horatio Alger’s stories, often remembered as the representative tale of American rags to American riches, romanticized not just the social and economic power of hard work, but also the power of old-fashioned good luck. The myths will live on: They confirm a deeply held value in American culture, allowing us residents to hold onto the idea: that we live in a meritocracy (精英体制). That our widely imitated and yet unusual take on democracy has been built, and continues to rest, on a system that ensures talent and hard work will be rewarded. Current events have helped to reveal the notion of meritocracy to be what it always was: yet another myth. During a discussion at the Aspen Ideas Festival, NPR’s Michele Norris talked with Darren Walker, the president of the Ford Foundation, and Jeff Raikes, the co-founder of the Raikes Foundation, emphasizing the tensions between how we talk about the American dream and how people live it. “As Americans, we want to believe you can get on that mobility escalator and ride it as far as you want,” Walker said, “but that no one rides it faster than anyone else.” We want to believe talent will triumph, and that hard work will be the tool of that success. Which is: We want to believe that opportunity is evenly distributed. However, this country, as Walker put it, “was constructed on a racialized hierarchy.” It’s a hierarchy that remains today, which is evident across American culture, across the American education system, across the American economy. And yet our myths tend to belie that reality. The logic of meritocracy - “a system where the talented are chosen and moved ahead, and their progress is based on ability and talent rather than on class privilege or wealth” - supports a world where economic success carries a moral value, and where, as a consequence, the lack of such success implies a kind of moral failing. “Meritocracy” takes as its core assumption, essentially, an equality that doesn’t exist in America. It is romantic rather than realistic. 1．Why is The Surprising Adventures of Baron Munchhausen and Horatio Alger’s stories mentioned in Para.1? A．To reveal the impact of American culture on literature. B．To explore the social and economic power of hard work. C．To exemplify the cultural origin of American meritocracy. D．To uncover the meritocracy in the American myth. 2．What does the author mean by saying the notion of meritocracy is “yet another myth” (Para.3)? A．The notion of meritocracy is deep-rooted in American legends. B．The so-called legendary meritocracy doesn’t exist. C．Democracy has been built on the basis of meritocracy. D．Meritocracy reveals another mysterious American dream. 3．Which of the following statements may Mr. Walker agree with? A．Those who work hard will be rewarded with opportunities. B．Americans still live in a society stressing the social hierarchy. C．Economic success is more dependent on moral success. D．Talent will triumph by employing the tool of diligence properly. 4．Which of the following is similar to the meaning of “belie” in Para.6? A．mask B．convert C．expose D．identify 2. 语法填空 Even with trickling rain and security risks, Paris has successfully kicked off the 2024 Olympics in its uniquely romantic manner. Not the traditional way, not 1 (safe)way, but certainly the most Parisian way — the French capital impressed the world significantly on Friday by turning the central section of the River Seine 2 a giant open-air theater. Eighty-five boats carrying athletes from 205 delegations sailed into the Olympic spotlight, cheered on by over 320,000 spectators watching from both banks of the river, and from balconies and windows. It was the first time in the history of modern Olympics that the Games’ opening ceremony 3 (move)out of a stadium. The bold innovation successfully took shape on the world’s biggest stage, 4 world-famous singers such as Celine Dion performed, echoing Paris 2024’s official slogan’ Games Wide Open’. 5 made the opening ceremony unforgettable was that the parade of athletes started from the Austerlitz Bridge and sailed along the Seine on boats behind their flag bearers, 6 (pass)by numerous monuments on both banks. It was 7 the Olympians were taking a journey through the country’s rich history and cultural heritage. French President Emmanuel Macron then declared the opening of the Games, kicking off a spectacular light show 8 (feature)laser beams shot from the Eiffel Tower that illuminated the Parisian night. French Olympic champions Marie-Jose Perec and Teddy Riner 9 (light)the ring of flames suspended by a giant balloon. It rose into the air over the Tuileries Garden 10 an honor to the first human flight in a hot-air balloon that took place at the same location in December 1873. 书面表达 你校最近举办了年度运动会，请你为校英文报写一篇报道。内容包括： 1. 时间和地点；2. 运动会的基本情况； 3. 比赛的意义。 注意：1.写作词数应为80左右；2.请按如下格式在答题卡的相应位置作答。 Annual School Sports Meeting _____________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ 1 / 9 学科网（北京）股份有限公司 $ Unit 1 No Limits Period 5 E Cultural focus分层练习 基础达标 01 能力提升 02 拓展培优 03 1. 词汇拼写 1.

The phrase “by the bootstraps”, describing those who have found success through dogged work and stubborn will, rose from The Surprising Adventures of Baron Munchausen : the aristocrat (贵族) pulls himself from a swamp - not by his bootstraps, but by his hair. And Horatio Alger’s stories , often remembered as the representative tale of American rags to American riches, romanticized not just the social and economic power of hard work, but also the power of old-fashioned good luck. (美国文化孕育了许多关于努力工作的道德价值的神话。“靠脚带”一词，描述那些通过顽强的工作和顽强的意志取得成功的人，源自《蒙乔森男爵的惊人冒险》：贵族从沼泽中挣脱出来——不是靠脚带，而是靠头发。霍雷肖·阿尔杰的故事，经常被人们铭记为美国从贫穷到富裕的代表性故事，不仅将辛勤工作的社会和经济力量浪漫化，还将老式好运的力量浪漫化。)”可知，作者使用这些例子是为了说明美国关于通过个人努力和社会流动性实现成功的神话，作者强调的是这些故事在美国文化中对个人成功和勤劳价值观念的影响，而这种影响正是美国社会中关于精英体制神话的基础。因此，文章提及《孟乔森男爵历险记》和霍雷肖·阿尔杰的故事，是为了例证美国精英体制的文化起源。故选C项。 2．推理判断题。根据文章第三段中“Current events have helped to reveal the notion of meritocracy to be what it always was: yet another myth. (当前的事件有助于揭示精英管理的概念：又一个神话。)”可知，所谓的传奇式的精英体制不过是另一个神话，暗示它并非真实存在。故选B项。 3．推理判断题。根据文章第五段中“However, this country, as Walker put it, “was constructed on a racialized hierarchy.” (然而，正如沃克所说，这个国家“是建立在种族化的等级制度之上的”。)”可知，沃克先生提到美国是建立在种族化的等级制度之上的，这种等级制度在当今美国文化、教育系统和经济中仍然显而易见。因此，他可能会同意美国人仍然生活在一个强调社会等级的社会中。故选B项。 4．词义猜测题。根据文章第五段中“It’s a hierarchy that remains today, which is evident across American culture, across the American education system, across the American economy. (这是一种至今仍然存在的等级制度，在美国文化、美国教育体系和美国经济中都很明显。)”和文章第六段中““Meritocracy” takes as its core assumption, essentially, an equality that doesn’t exist in America. It is romantic rather than realistic. (“精英政治”的核心假设，本质上是美国不存在的平等。这是浪漫的，而不是现实的。)”以及划线词所在的句子“And yet our myths tend to (然而，我们的神话往往)”可知，前文提到美国存在种族等级制度等现实情况，后文又指出了本质上美国不存在平等，所以，“belie”意为遮掩或掩饰某种真实情况，与mask (掩饰)意义相近。故选A项。 2. 语法填空 Even with trickling rain and security risks, Paris has successfully kicked off the 2024 Olympics in its uniquely romantic manner. Not the traditional way, not 1 (safe)way, but certainly the most Parisian way — the French capital impressed the world significantly on Friday by turning the central section of the River Seine 2 a giant open-air theater.
