说到「沃尔玛」，很多人第一时间想到的，可能都是它遍布全美的实体大卖场，或者「山姆会员商店」。自 1962 年开设第一家门店以来，沃尔玛始终专注于实体零售经济，凭借「天天低价」的承诺，成为中低收入美 国人的首选零售商，并在 1990 年登顶美国零售业榜首。 其实，沃尔玛对电商的探索可以追溯到上世纪。1996 年，沃尔玛上线了自己的在线商店，但业内普遍认为这 更像是一场实验，而非长期战略。尽管后来成立了电商部门、收购相关企业，沃尔玛的重心依然放在实体零 售。 正如《财富》杂志所说，沃尔玛长期陷入「创新者的困境」——作为线下零售巨头，他们担心电商业务长期需 要现金流补贴，会蚕食本已成熟的实体零售，因此在电商探索上显得保守。这也让「亚马逊」抓住机会，成为 电商领域的一家独大。 ▲ 图源：华尔街日报 eMarketer 的分析师指出，在疫情爆发之前，沃尔玛的电商业务发展缓慢。但疫情开始后，美国消费者大规模 转向线上购物，这打破了沃尔玛内部「门店优先」的既得利益格局，也倒逼他们打通线上线下，迫使他们改造 并利用现有门店网络来满足飙升的在线订单需求。 《经济学人》认为，沃尔玛的最大优势就是 实体布局 。行业数据显示，沃尔玛 ...

编者按 这篇文章转载自我们的好朋友——尼可学院，文章是他们少年们准备的系列英文阅读营。 虽然大多数的地方，还在继续让孩子们刷题考卷，尼可学院坚定地认为，我们必须直面社会的剧烈变 化。况且，能够理解AI对个人，对社会所带来的变化本身，就不简单。 在这个暑假，我们希望通过有厚度的人文思辨故事和面向未来的科普，认知心理等领域的书籍，和少 年们，从不同的角度来理解社会正在经历的变化。 文｜Nicole AI在技术上突破，并愈来愈进入日常的时候，我们是该把孩子们阻挡在外，让他们继续工业时代的考卷， 还是积极跟他们一起理解这个剧烈的变化？ 在AI世界，一个孩子能去探索成功的重要品质是什么？ 我希望我的孩子拥有的品质是，勇气。 在复 杂的事情面前，并不畏惧。也不以"现状"定义自己。去行动，去改变。 转载这篇文章，其实是在做青少年节目「Knock Knock 世界」时，我们接触到了很多优秀的教育品牌，尼可 学院就是其中之一。他们从 2017 开始做全英语阅读，到现在已经 8 年了。他们理想中的阅读不是单纯追求 英语成绩，而是把「学习者」作为主体，关注他们在学习中的状态，并通过阅读和讨论，支持学习者获得 真实的英语能力和自主探 ...

二是，我们制作了一枚儿童节专属贴纸送给前 2500 位小宇宙的付费听友。 首先说儿童节特别节目。特别之处在于，它是由我们的少年朋友 Summer 跟主播赛德共同录制的，并且节目开头还有一段大家一起在线下选题会录制的声音片段。 所以这期节目算是我们跟少年们共同的内容作品啦。 其实，这也不是我们第一次跟少年们一起「工作」：从最开始节目上线前，就有 9 位少年「特约节目顾问」帮我们出谋划策，在节目名称、内容和声音及视觉设 计等方面提供各种各样的反馈和主意。比如，我们在放出 F1 赛车这期试听节目之前，就有一位顾问提到自己也会看 F1 赛车直播，每次看到车手摘下头盔都是满 头大汗的，但从没想过为什么，听了节目才恍然大悟——原来赛车手在比赛中的体能消耗非常大，一场比赛下来能出两三瓶矿泉水那么多汗！ 节目制作过程中，我们每天都能收到来自世界各地「全球观察员」的投稿，他们带着自己的好奇提问，大大打开了我们的思路，有的好奇已经被制作成节目播 出。 （上下滑动） Hi 各位， 这里是「Knock Knock 世界」编辑部。马上就到六一儿童节了，这个一听就非常快乐的日子，必须搞点仪式感庆祝一下！有两件大事跟大家宣布： 一是，我们 ...
