Finally, personal data is not yet secure. Nonetheless, 9. is in no doubt is that the sharing economy is 10. (increase) relevant to our daily lives as well as to the global economy.
What’s mine is yours.
We’ve been told since we were toddlers that “It’s good to share”.Parents and teachers keep reminding us to share toys, snacks, books, happy memories, and sometimes even sorrows① with others.When we grow up, we share photos, life stories and opinions with people around us and with those we don’t know via social media. [1]Taking it as an object② of study, psychologists have published various papers③ stating④ that the behaviour of sharing is beneficial to⑤ setting up⑥ positive emotional bonding.
[1] 本句为主从复合句。Taking it as an object of study为动词-ing短语作状语;that引导宾语从句。
Today, the action of sharing takes on⑦ extra meaning.It’s not just about sharing sweets or frustration⑧; it has expanded to almost every aspect of our lives — the whole world seems to be into sharing.We are using technology to reduce the money that we spend on goods and services, or to make money out of those that we don’t use ourselves all of the time.These vary from car shares to⑨ home shares, and even to pet shares.The sharing economy is taking off⑩ in all sorts of areas.It is creating new ways of thinking and is providing services to people when and where they want them.
This wealth of ways of sharing is a response⑪ to our increasing demand for⑫ quality goods and services at competitive⑬ prices, [2]all delivered⑭ at the click of⑮ a button.[3]Whether it’s an online shop where we can hire designer clothes⑯ at rock-bottom prices⑰, or a platform from which we can rent out⑱ our flats for a couple of days⑲, it’s out there.Whether we’re a lender or a borrower, it’s a win-win situation; everyone makes or saves money.We also make connections and sometimes even make new friends.What’s more, sharing encourages us to reuse items, thereby cutting down⑳ on waste.And set-ups such as bike and car sharing do a further favour for the environment by reducing the number of polluting vehicles on the road.
[2]all delivered at the click of a button为独立主格结构。
[3]句中Whether ...or ...引导让步状语从句;其中where引导定语从句,先行词为shop;from which we can ...a couple of days为“介词+关系代词”引导的定语从句。
But the sharing economy is not without its problems.[4] As is often the case all over the world with new areas of economic activity, the sharing economy is developing faster than existing regulations㉑ or ongoing supervision㉒.Some companies are taking unfair advantage of㉓ this situation to expand their share㉔ of the market, often at the expense㉕ of more traditional and established companies.In addition, the sharing economy is subject to㉖ abuse㉗ of trust.Some people have experienced damage to their properties㉘ whilst renting out their homes, and others have found themselves victims㉙ of theft㉚ or attack while sharing rides.Finally, personal data, the heart of the sharing economy, is not yet secure㉛.Sharing platforms collect personal information about almost every part of our lives, including our names, locations, bank information, and individual preferences for goods and services.Yet, the technology to prevent such information from leaking or being stolen still needs improvement, and the awareness of potential risks㉜ is low among both service providers and users.
Nonetheless㉝, what is in no doubt is that the sharing economy is increasingly relevant to㉞ our daily lives as well as to the global economy.[5]It is expanding at such a rate that we can only imagine what it will comprise in the future. What will we be sharing next? Who will be sharing and how? And the most interesting question of all — what type of society will all this sharing take us to?
[4]句中As为关系代词,引导非限制性定语从句,在句中作主语。

我的就是你的
我们还在蹒跚学步的时候就被教导“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,会与周围的人或者是社交媒体上不认识的人分享照片、人生经历和观点。心理学家们将分享作为研究的对象,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。
如今,分享行为又多了额外的含义。不仅仅是分享糖果或挫折,分享行为几乎已经扩大到生活的方方面面——整个世界似乎都在分享。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红火起来,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。
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一键单击来实现。无论是以最低价格出租名牌服装的网店,还是可以把自己的公寓短租几天的平台,都已出现。这对于出租者和租用者来说都是一个双赢的局面;人人都能挣钱,或都能省钱。我们可以建立联系,有时候甚至可以交到新朋友。不仅如此,共享方式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会进一步保护环境,因为它们减少了行驶在路上的污染排放车辆的数量。
但共享经济并非没有问题。世界上新出现的经济领域通常都是如此,共享经济的发展速度过快,而现有法规和持续监管还未跟上。一些公司正在利用这种情况获取不公平的优势,来扩大市场份额,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涵盖我们生活的方方面面,包括姓名、位置、银行信息、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。
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?
