A rash, unexpected move by Yoon Suk Yeol, the president, tests South Korean democracy 正文：December 3rd began as an uneventful early-winter day in Seoul, South Korea’s capital.

But who, then, would check the judges? One answer was that the president would be able to pardon criminals. This awesome power—to override a decision taken by the courts—should be used rarely, because it is at odds with democracy and judicial independence. If it seems a bit medieval to let one man dispense (and dispense with) justice in this way, that is because it is. In British law the “prerogative of mercy” can be traced back to the reign of King Ine of Wessex in the seventh century. 知识点：set up If you set something up, you create or arrange it. 安排; 创建 • The two sides agreed to set up a commission to investigate claims. 双⽅同意成⽴⼀个委员会，调查索赔问题。 • ...an organization which sets up meetings about issues of interest to women. …⼀个安排有关妇⼥利益问题的会议组织。 获取外刊的完整原文以及精讲笔记，请关注微信公众号「早安英文」，回复“外刊”即可。更多有意思的英语干货等着你！ 【节目介绍】 《早安英文-每日外刊精读》，带你精读最新外刊，了解国际最热事件：分析语法结构，拆解长难句，最接地气的翻译，还有重点词汇讲解。 所有选题均来自于《经济学人》《纽约时报》《华尔街日报》《华盛顿邮报》《大西洋月刊》《科学杂志》《国家地理》等国际一线外刊。 【适合谁听】 1、关注时事热点新闻，想要学习最新最潮流英文表达的英文学习者 2、任何想通过地道英文提高听、说、读、写能力的英文学习者 3、想快速掌握表达，有出国学习和旅游计划的英语爱好者 4、参加各类英语考试的应试者（如大学英语四六级、托福雅思、考研等） 【你将获得】 1、超过1000篇外刊精读课程，拓展丰富语言表达和文化背景 2、逐词、逐句精确讲解，系统掌握英语词汇、听力、阅读和语法 3、每期内附学习笔记，包含全文注释、长难句解析、疑难语法点等，帮助扫除阅读障碍。

Welcome to a high-tech utopia 正文：In “permutation city”, a novel by Greg Egan, the character Peer, having achieved immortality within a virtual reality over which he has total control, finds himself terribly bored. So he engineers himself to have new passions. One moment he is pushing the boundaries of higher mathematics; the next he is writing operas. “He’d even been interested in the Elysians [the afterlife], once. No longer. He preferred to think about table legs.” Peer’s fickleness relates to a deeper point. When technology has solved humanity’s deepest problems, what is left to do? 知识点：utopia/juːˈtəʊpɪə/ If you refer to an imaginary situation as a utopia, you mean that it is one in which society is perfect and everyone is happy. 理想社会; 乌托邦 • We weren‘t out to design a contemporary utopia. 我们不想去设计⼀个当代乌托邦。 获取外刊的完整原文以及精讲笔记，请关注微信公众号「早安英文」，回复“外刊”即可。更多有意思的英语干货等着你！ 【节目介绍】 《早安英文-每日外刊精读》，带你精读最新外刊，了解国际最热事件：分析语法结构，拆解长难句，最接地气的翻译，还有重点词汇讲解。 所有选题均来自于《经济学人》《纽约时报》《华尔街日报》《华盛顿邮报》《大西洋月刊》《科学杂志》《国家地理》等国际一线外刊。 【适合谁听】 1、关注时事热点新闻，想要学习最新最潮流英文表达的英文学习者 2、任何想通过地道英文提高听、说、读、写能力的英文学习者 3、想快速掌握表达，有出国学习和旅游计划的英语爱好者 4、参加各类英语考试的应试者（如大学英语四六级、托福雅思、考研等） 【你将获得】 1、超过1000篇外刊精读课程，拓展丰富语言表达和文化背景 2、逐词、逐句精确讲解，系统掌握英语词汇、听力、阅读和语法 3、每期内附学习笔记，包含全文注释、长难句解析、疑难语法点等，帮助扫除阅读障碍。
