我们自蹒跚学步时就被叮嘱“要懂得分享”。父母和老师不断地提醒我们要与他人分享玩具、零食、书籍以及快乐的回忆，有些时候甚至要分享自己的伤心事。我们长大后，会与周围的人或是通过社交媒体与不认识的人分享照片、人生经历和观点。心理学家们将其作为研究的对象，发表了各种各样的论文来说明分享行为有助于建立积极的情感纽带。 2 如今，分享行为呈现出额外的含义。不仅是分享糖果或挫折，它已经扩展到几乎生活的方方面面——全世界似乎都在分享。我们正在利用科技来减少在商品和服务上的花费，或者用我们一直闲置的物品赚钱。从汽车共享到住房共享，甚至是宠物共享。共享经济正在各个领域发展起来，它创造着新的思维方式，随时随地为有需求的人们提供服务。 3 我们需要价格有竞争力的优质产品和服务，大量的共享方式是对这种不断增长的需求的回应，现在这些需求都可以通过按一下按钮来实现。无论是我们能以最低价格租用名牌服装的网店，还是可以把自己的公寓短租几天的平台，都已出现。无论我们是出租者还是租用者，这都是一个双赢的局面；人人都能挣钱，或都能省钱。我们也可以建立联系，有时候甚至可以交到新朋友。不仅如此，共享鼓励我们将物品再次利用，从而减少浪费。共享单车、共享汽车等计划的实施通过减少路上排放污染的车辆的数量进一步保护环境。 4 但共享经济并非没有问题。正如世界各地新的经济活动领域经常出现的情况一样，共享经济的发展速度比现行法规和正在进行的监管更快。一些公司正在利用这种情况获取不公平的优势，来扩大他们的市场份额，通常以牺牲已有的更为传统的公司为代价。此外，共享经济容易受到信任滥用的影响。有些人出租房屋时财物遭到破坏，还有人搭顺风车时成为盗窃甚至袭击的受害者。最后一点，个人数据，即共享经济的核心，也并不安全。共享平台收集的个人信息几乎涵盖我们生活的方方面面，包括我们的姓名、位置、银行信息及对商品和服务的个人偏好。然而，防止信息泄露或被盗的技术仍然有待改进，服务方和用户对潜在风险的防范意识也较低。 5 尽管如此，共享经济无疑正在与我们的日常生活以及全球经济产生越来越密切的联系。它飞速扩张，我们只能想象它将来会包含什么。我们下一个共享的对象将会是什么？将由谁来共享以及如何共享？最有趣的问题是——这些共享将会带我们进入什么样的社会？ 学生用书第107页 ◎核心单词——练通 1．superior intelligence 更强的智力 2．looked at him in mild
