share”．Parents and teachers keep reminding us to share toys, snacks, books, happy memories, and sometimes even sorrows② with others.When we grow up, we share photos, life stories and opinions with people around us and with those we don't know[1]via③ social media.Taking it as an object of study, psychologists have published various papers stating that the behaviour of sharing is beneficial to④setting up⑤ positive emotional bonding⑥.[2] [1]画线部分为省略了引导词who的定语从句，修饰先行词those。 [2]Taking it...study为现在分词短语作状语；stating that...bonding为现在分词结构作定语，修饰papers，其中that引导宾语从句。 2 Today, the action of sharing takes on⑦ extra meaning.It's not just about sharing sweets or frustration⑧； it has expanded⑨ 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.[3]These vary from car shares to home shares, and even to pet shares.The sharing economy⑩ is taking off⑪ in all sorts of areas.It is creating new ways of thinking and is providing services to people when and where they want them.[4] [3]句中第一个that引导定语从句，修饰the money；第二个that也引导定语从句，修饰those。 [4]画线部分为when和where同时引导的状语从句。 3 This wealth⑫ of ways of sharing is a response to⑬our increasing demand for quality goods and services at competitive prices，all delivered ⑭at the click of a button⑮.Whether it's an online shop where we can hire⑯designer clothes⑰ at rock­bottom prices⑱， or a platform from which we can rent out⑲ our flats for a couple of days[5], it's out there.Whether we're a lender or a borrower, it's a win­win situation⑳； everyone makes or saves money.We also make connections and sometimes even make new friends.What's more，sharing encourages us to reuse items, therebyeq \o(○,\s\up3(21))cutting down oneq \o(○,\s\up3(22)) waste.And set­ups such as bike and car sharing do a further favour for the environment by reducing the number of polluting [6]vehicles on the road. [5]本句为Whether...or...引导的让步状语从句。状语从句中where引导定语从句，修饰先行词an online shop，关系词在从句中作地点状语；from which引导定语从句，修饰先行词a platform。 [6]画线部分为v.­ing作定语，修饰vehicles，动词pollute与vehicles之间为逻辑上的主谓关系。 4 But the sharing economy is not without its problems.As is often the case，[7] all over the world with new areas of economic activity, the sharing economy is developing faster than existing regulationseq \o(○,\s\up3(23)) or ongoingeq \o(○,\s\up3(24))supervisioneq \o(○,\s\up3(25)).Some companies are taking unfair advantage ofeq \o(○,\s\up3(26)) this situation to expand their share of the marketeq \o(○,\s\up3(27))， often at the expense of eq \o(○,\s\up3(28)) more traditional and established companies.In addition, the sharing economy is subject to eq \o(○,\s\up3(29)) abuseeq \o(○,\s\up3(30)) of trust.Some people have experienced damage to their propertieseq \o(○,\s\up3(31)) whilst eq \o(○,\s\up3(32)) renting out their homes, and others have found themselves victimseq \o(○,\s\up3(33))of thefteq \o(○,\s\up3(34)) or attack while sharing rides. Finally, personal data, the heart of the sharing economy, is not yet secureeq \o(○,\s\up3(35)).Sharing platforms collect personal information about almost every part of our lives, including our names, locations, bank information, and individual preferenceseq \o(○,\s\up3(36)) for goods and services.Yet, the technology to prevent such information from leakingeq \o(○,\s\up3(37)) or being stolen still needs improvement, and the awareness of potential risks is low among both service providers and users. [7]画线部分意为“情况常常如此”，As在此引导非限制性定语从句。 5 Nonetheless, what is in no doubt is that the sharing economy is increasingly relevant to our daily lives as well as to the global economy.[8] It is expanding at such a rateeq \o(○,\s\up3(38)) that we can only imagine what it will compriseeq \o(○,\s\up3(39)) in the future.[9]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 toeq \o(○,\s\up3(40))？ [8]本句中Nonetheless意为however/despite this fact，起到让步、转折的功能。what is...is that...结构中what引导主语从句，that引导表语从句。 [语用]　what is...is that...结构既可以让表达更简洁，避免头重脚轻的情况，还可以起到对主语和表语内容的强调作用。 [9]画线部分为such...that...结构，that引导结果状语从句；其中的what引导宾语从句。 参考译文 我的就是你的。 1．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。 2．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。 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。 4．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，以扩大市场份额，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。 Ⅰ.Reading for main idea Read the passage quickly and choose the best answer.
