原因之一在于阅读本身。29.A。推断。第三段But后面的部分采用“先观点后举例”的写作方式，本段末尾的数据主要说明前面的观点the latest data regarding libraries is worrying,即：图书馆处境艰难。30.D。理解文章结构、类型。根据划线词后的from Susan Orlean's The Library Book toMatt Haig's The Midnight Library可知，所列举的作品均和图书馆有关，因此，是图书馆激发了作者的写作灵感。31.B。推断。作者在最后一段表达了自己对图书馆里的书籍的看法，认为它们有一点是很特别的，那就是经过别人的手后再传到你手中，并且还会继续在与你有共同好奇心的陌生人之间传递下去。由此不难看出，作者认为图书馆里的书籍在阅读者们之间建立起了某种联系。破折号后的and that与前面的hat并列，修饰a copy。【语言知识】l.practicalities:实际情况，常用复数。2.on the previous year::和上一年相比，on在此意为“与…相比”。3.silver lining:一线希望D篇主题语境：人与社会一一科学与技术本文是说明文。文章介绍了意大利的网络使用人数少这一现象及其原因以及该国为实现数字化而采取的改进措施。32.C。推断。第二段提到意大利的网络用户占比少的原因有三点：一是老年人口多，中位数年龄在欧洲位居榜首(elderly population:it has the EU's highest median age),二是当政8年的前总理西尔维奥·贝卢斯科尼认为互联网代表商业威胁(the internet represented acommercial danger),三是该国占主导地位的固定电话运营商Telecom Italia有意放缓宽带的引入，以维持其自身网络的价值(had an interest in slowing the introduction of broadband tomaintain the value of its own network)。由此可知，C项是在第二点原因的基础上推断而来的。B项过度推测，文中只提到老年人多，但并没有说老年人拒绝使用手机。33.D。理解具体信息。根据第三段中的Mr Colao also wants to help the3 m or so Italianswho have been left behind by the digital revolution acquire basic computer skills,Mr Colao的目标之一是要让没有跟上数字革命步伐的约300万意大利人获得基本的计算机技能。因此，他想普及电脑知识。34.C。理解具体信息。根据倒数第二段末尾Mr Colao所说的I showed it to a Germanpolitician.He was open-mouthed可知，这位德国攻治家对意大利的IO应用程序感到吃惊。35.B。推断。Mr Colao在最后一段中说的话是为了说明上文中的The pandemic has helpedin other ways too,.再结合他说的e-commerce has now become absolutely normal可知，他认为疫情促进了意大利的数字化。C项曲解文意，文中说意大利的数字化一直比较落后，本身就不正常，因此疫情并不是使意大利的电子商务恢复正常，而是使其开始变得正常了。【语言知识】1.be charged with:使…承担任务2.social-security contributions::社会保障税【背景知识】l.Galileo and Marconi::伽利略和马可尼，分别是意大利的物理学家和无线电工程师。2.median age:年龄中位数或中位年龄，是将全体人口按年龄大小排列，位于中间位置的人的年龄数值。年龄分布在这个数值以上的人数和以下的人数相等。年龄中位数越高，说明人口老龄化越严重。第二节
