体裁微解——说明文
说明文通常是通过举例子、作比较、分类别、析结果、列数字和作引用等手段，具体描述一项研究或者介绍一项新产品、新技术的文章，旨在让读者了解信息。说明文通常不包含作者的个人观点。主要具有以下特点：
选材 实验报告、产品介绍、场馆介绍、社会现象分析以及语言文化、人文地理、生物的生存状况等。
内容 用平实的语言客观解说事物、解释现象、提供信息，即说明一个事物或说明一项研究。
形式 总分式(事物说明文常用“总—分”式、“总—分—总”式结构)；递进式(事理说明文由浅入深、由表及里、由现象到本质，逐层递进，剖析事理)；并列式(文章各部分内容没有主次轻重之分)；对照式(通过两个事物的对照和比较说明其异同)。
语言 主要考查考生对词汇和句式的掌握和运用情况。说明文因其生僻词汇多、句式复杂等特点，相对于其他体裁的文章来说难度更大。
命题 主要集中在细节理解题、推理判断题、主旨大意题或词义猜测题。出题人经常在长难句上做文章。
说明文阅读量大，生僻词汇多，句式结构复杂，题目往往涉及推理判断题和主旨大意题。因此，阅读这类文章时，应把握文章结构，弄清作者所要说明的事物；另外，考生在平时的学习中应多积累阅读词汇，提高分析长难句的能力。具体答题策略如下：
解题策略
策略指导 技法解读
抓首尾段 首段往往提出说明文的主题，尤其是研究类说明文，研究结果就是主题；尾段往往重申、强调主题。
梳理文章结构 整体叙述＋细节或过程说明＋概括评述；现象＋原因＋后果/启示/措施；研究发现/调查结果＋研究/调查过程。
破解长难句 结合语境和所学语法知识破解结构复杂的长难句。
The goal of this book is to make the case for digital minimalism，including a detailed exploration of what it asks and why it works，and then to teach you how to adopt this philosophy if you decide it’s right for you.

语篇解读
本文是一篇说明文。文章主要介绍了数字极简主义生活方式的优点，倡导简单的数字生活方式。
To do so，I divided the book into two parts.In part one，I describe the philosophical foundations of digital minimalism，starting with an examination of the forces that are making so many people’s digital lives increasingly intolerable，before moving on to a detailed discussion of the digital minimalism philosophy.
Part one concludes by introducing my suggested method for adopting this philosophy: the digital declutter.This process requires you to step away from optional online activities for thirty days.At the end of the thirty days，you will then add back a small number of carefully chosen online activities that you believe will provide massive benefits to the things you value.
In the final chapter of part one，I’ll guide you through carrying out your own digital declutter.In doing so，I’ll draw on an experiment I ran in 2018 in which over 1,600 people agreed to perform a digital declutter.You’ll hear these participants’ stories and learn what strategies worked well for them，and what traps they encountered that you should avoid.
The second part of this book takes a closer look at some ideas that will help you cultivate(培养) a sustainable digital minimalism lifestyle.In these chapters，I examine issues such as the importance of solitude(独处) and the necessity of cultivating high-quality leisure to replace the time most now spent on mindless device use.Each chapter concludes with a collection of practices，which are designed to help you act on the big ideas of the chapter.You can view these practices as a toolbox meant to aid your efforts to build a minimalist lifestyle that works for your particular circumstances.
28.What is the book aimed at
A.Teaching critical thinking skills.
B.Advocating a simple digital lifestyle.
C.Solving philosophical problems.
D.Promoting the use of a digital device.

For the first time，scientists have measured what actually happens with face-to-face interactions when employees start to work at an open-plan office，and their results show these modern workspaces are not as cooperative as you’d think.
随堂演练
语篇解读
本文是一篇说明文。一项研究表明，在开放式办公室工作时，员工并不像你想象中的那样合作，反而为了保护隐私，他们互动减少，更多地使用电子邮件交流。
Two researchers from Harvard Business School and Harvard University wanted to test whether removing walls at a real-world workplace really increases interactions between co-workers.“To our knowledge，no prior study has directly measured the effect on actual interaction that results from removing walls to create an open office environment，” Ethan S.Bernstein and Stephen Turban write in the paper.To that end，they approached two multinational companies that were re-organizing their office spaces at the global headquarters，and enlisted small groups of employees for two studies.
For eight weeks before the office redesign and eight weeks afterward，the researchers tracked employees’ social interactions and locations.This data was analyzed together with email and instant messaging information from the company’s servers to measure differences in how people were communicating with each other.
What they found was a pretty astonishing difference in face-to-face interactions—but not in the direction you might think.Across both experiments，employees’ social interactions in person decreased by a crazy 70 percent，while emails saw an uptick by roughly 20 to 50 percent.
So，instead of spending more time cooperating with co-workers in the new space where everyone could see them，people got their heads down and tried to preserve their privacy any way they could.According to these results，it appears that being forced into a more open-plan environment can make people switch from chatting to others in person to sending an email or using instant messaging instead.
As the team notes，it’s not automatically a bad thing，but it can certainly change work dynamics in an unexpected way.“That can have important consequences for how—and how productively—work gets done，” the researchers conclude.
1.How did the two multinational companies redesign their offices
A.By expanding the total floor areas.
B.By updating the computer servers.
C.By changing the employees’ locations.
D.By tearing down the space boundaries.
√
细节理解题。由第二段中的“To our knowledge，no prior study has directly measured the effect on actual interaction that results from removing walls to create an open office environment”和“To that end，they approached two multinational companies that were re-organizing their office spaces...”可知，为了做研究，研究人员联系了两家跨国公司，这两家公司通过打破空间边界(即拆除墙壁)来重新设计办公室。故选D。
2.Why did the employees prefer email or instant messaging in an open office space
A.To reduce the risk of privacy leaks.
B.To establish efficient communication.
C.To facilitate indirect social interaction.
D.To transform traditional work patterns.
√
细节理解题。由倒数第二段首句“So，instead of spending more time cooperating with co-workers in the new space where everyone could see them，people got their heads down and tried to preserve their privacy any way they could.”可知，员工更喜欢在开放式办公场所通过发电子邮件或即时消息进行交流，是因为他们想降低隐私泄露的风险。故选A。
3.What can be inferred from the researchers’ saying in the last paragraph
A.Further relevant research needs conducting.
B.Their research findings are of practical value.
C.Their team intends to change working environment.
D.People hold different opinions on how work gets done.
√
推理判断题。由最后一段中的“‘That can have important consequences for how—and how productively—work gets done，’the researchers conclude.”可知，研究人员认为他们的研究结果具有实用价值。故选B。
4.What is the main idea of the text
A.Real-world workplaces increase employees’ interaction.
B.Work dynamics don’t have much effect on work efficiency.
C.Modern workspaces change workers’ way of communication.
D.Open-plan offices can’t promote cooperation between co-workers.
√
主旨大意题。 综合分析全文尤其通过倒数第二段可知，文章介绍了一项研究，该研究表明，在开放式办公室工作时，员工并不像你想象中的那样合作，反而为了保护隐私，他们互动减少，更多地使用电子邮件交流，D项“开放式办公室不能促进同事之间的合作”符合文意。故选D。

Machine learning sees reasoning as a categorization task with a fixed set of predetermined labels.It views the world as a fixed space of possibilities，calculating and weighing them all.This approach，of course，has achieved notable successes when applied to stable and well-defined situations such as chess or computer games.When such conditions are absent，however，machines struggle.
语篇解读
这是一篇说明文。短文介绍了心理人工智能可以让人工智能变得更聪明。
In 2008，Google launched Flu Trends，a web service that aimed to predict flu-related doctor visits using big data.The project，however，failed to predict the 2009 H1N1 flu outbreak.After several unsuccessful adjustments to its algorithm(算法)，Google finally stopped the project in 2015.
In such unstable situations，the human brain behaves differently.
Sometimes，it simply forgets.Instead of getting trapped in irrelevant data，it relies only on the most recent information and makes creative decisions.This is a feature called intelligent forgetting.Adopting this approach，an algorithm that relies on a single data point would have reduced Google Flu Trends’ prediction error by half.
Intelligent forgetting is just one dimension of psychological AI，an approach to machine intelligence that also includes other features of human intelligence such as causal reasoning，intuitive(直觉) psychology，and physics.Soon，this approach to AI will finally be recognized as fundamental for solving poorly-defined problems.Exploring these amazing features of the human brain will finally allow us to make machine learning smart.
One feature of psychological AI is that it is explainable.Until recently，researchers assumed that the more transparent an AI system was，the less accurate its predictions were.This mirrored the widespread but incorrect belief that complex problems always need complex solutions.Now，this idea will be laid to rest.As the case of flu predictions illustrates，powerful and simple psychological algorithms can often give more accurate predictions than complex algorithms.Psychological AI opens up a new vision for explainable AI: Instead of trying to explain complex systems，we can check first if psychological AI offers a simple and equally accurate solution.
Without the help of human psychology，it will become clearer that the application of this type of machine learning to unstable situations eventually runs up against impassable limitations.We will finally recognize that more computing power makes machines faster.Not smarter.
5.Why is Flu Trends mentioned
A.To clarify a concept.
B.To tell the serious outbreak.
C.To support the author’s idea.
D.To provide readers with the truth.
√
推理判断题。根据第一段的后两句以及第二段内容可知，提到“流感趋势”是为了支持作者在第一段提出的观点。故选C。
6.What is the advantage of human brain according to the passage
A.It can think outside the box.
B.It can avoid unclear problems.
C.It is capable of learning over time.
D.It is good at following instructions.
√
推理判断题。根据第三段前三句可知，在不稳定的情况下，人类的大脑不会被无关的数据困住，而是只依赖于最新的信息，并做出创造性的决定。由此可推知，人脑的优势是可以跳出思维定式。故选A。
7.Which has the similar meaning with the underlined word “transparent” in paragraph 5
A.Similar. B.Unique.
C.Complete. D.Clear.
词义猜测题。根据第五段第三句可知，画线词所在句的观点反映了“复杂的问题总是需要复杂的解决方案”这一错误理念。由此可推知，画线词所在句句意为“研究人员认为人工智能系统越清晰，其预测就越不准确”。故画线词的意思是“清晰的”。故选D。
√
8.What does the author intend to tell us
A.AI speeds up the computing greatly.
B.Psychological AI can make smarter AI.
C.AI system works well in stable situations.
D.AI will outperform the human brain someday.
写作意图题。通读全文尤其根据第四段最后一句和最后一段第一句可知，作者想告诉我们心理人工智能可以让人工智能变得更聪明。故选B。
