What if we knew an alien civilisation was to invade （入侵） Earth? What would we do? These are the questions asked in The Three-Body Problem.When a secret military project sends signals into space to get in touch with aliens, an alien civilisation in the face of destruction receives the signals and plans to invade Earth. Meanwhile, on Earth, people begin to separate into different groups: those who welcome aliens and those who want to fight against them. The novel was written by Chinese author Liu Cixin and published in 2006.Translated into English in 2014 and almost 20 languages since, it was called an absolute “must-read in any language” by Booklist magazine. Liu has won several awards for it and in 2015, he became the first Asian to win the Hugo Award for Best Novel, the highest award in science fiction. 刷阅读理解 20 Just from the title, one could imagine that the text might be heavy with physics terms （术语）.But as US writer Jason Heller said, “Indeed this science fiction is full of lengthy passages explaining technical terms. But Liu Cixin supports all of that burning-brain theory with empathetic （感同身受的） characters and thrilling story plots.” At the very heart of science fiction—and what makes it truly appealing to readers—is the concept of an uncertain future. This allows the author to push back the boundaries of readers’ imaginations. Liu fully uses this approach to keep readers anxiously turning the page. While reading, they ask themselves, “What would I do?” In an interview with The New York Times, Liu said, “China is on the path of rapid modernisation and progress, kind of like the US during the golden age of science fiction from the 1930s to the 1960s. The future in the people’s eyes is full of not only attractions and hope, but also threats and challenges. That makes for very fertile soil.” 刷阅读理解 21 1.Why does the author ask the three questions in Paragraph 1?( ) B A.To warn us of the crisis Earth is faced with. B.To introduce the novel The Three-Body Problem. C.To show the author’s worries about Earth. D.To remind us to watch out for alien civilisations. 解析 推理判断题。作者在第一段中提出三个问题，再根据第二段第一句可知，这三个问题就是《三体》中被问到的问题，由此可知，作者在开篇提出三个问题是为了引出科幻小说《三体》。故选B项。 【语篇导读】本文是一篇议论文。文章是一篇书评，主要内容为刘慈欣的科幻作品《三体》的故事梗概、写作特点及其影响力等。 刷阅读理解 22 2.What can we know about the novel according to the passage?( ) C A.It is about a fight between aliens and an army on Earth. B.It was translated into many languages once published. C.It has gained worldwide recognition and great success. D.It targets the readers with a good knowledge of physics. 解析 细节理解题。根据第三段内容可知，该小说被翻译成近20种语言，被称为“任何语言的必读书”，刘慈欣也因此成为首位获得雨果奖最佳长篇小说奖的亚洲人。故选C项。 刷阅读理解 23 3.What does the underlined part in Paragraph 5 refer to?( ) C A.Explaining very difficult physics terms. B.Exploring the boundaries of readers’ imaginations. C.Applying the concept of an uncertain future. D.Encouraging readers to ask themselves questions. 解析 词义猜测题。根据第五段首句At the very heart of science fiction—and what makes it truly appealing to readers—is the concept of an uncertain future.可知，科幻小说吸引读者的核心所在就是不确定的未来；根据第五段第二句This allows the author to push back the boundaries of readers’ imaginations.中的This可推知，this approach与This所指内容相同：不确定的未来。故选C项。 刷阅读理解 24 4.What does Liu mean in the last paragraph?( ) A A.China is now in the golden age of science fiction. B.The US authors can’t create science fiction now. C.Now Chinese people are confused about the future. D.China’s progress mainly depends on fertile soil. 解析 推理判断题。根据文章最后一段中刘慈欣所说的China is on the path of rapid modernisation and progress, kind of like the US during the golden age of science fiction from the 1930s to the 1960s.可知，刘慈欣认为中国现在和二十世纪三十年代至二十世纪六十年代的美国一样，处于科幻小说发展的黄金时代。故选A项。 刷阅读理解 25 核心词汇 1.civilisation n.文明2.destruction n.毁灭3.thrilling adj.惊险的;扣人心弦的 刷阅读理解 26 B You might think a computer would be a fair judge, but a new study finds it might be better for you to put yourself in the hands of humans. AI won’t let people off easily when they break the rule! This study, conducted by a team at MIT, examined how AI would interpret perceived violations （违反） of a given code. They discovered the most effective data for AI training is normative data, where humans determine whether a rule has been violated. However, data used to train machine-learning models are typically labelled descriptively—meaning people label the factual features of a situation, and AI determines whether a code has been broken. 刷阅读理解 27 The team gathered images of dogs that could potentially violate an apartment rule banning aggressive types of animal. Groups were then asked to provide normative and descriptive responses. The descriptive team wasn’t informed about the policy on dogs, and was asked to identify whether elements, such as the dog’s aggression, were present. Their responses helped to form judgements. If a user said the photo described an aggressive dog, the policy was considered to be violated. On the other hand, the normative group was informed about the rule and was asked to determine whether each image violated the rule. Participants were 20 percent more likely to identify a code violation using the descriptive method. If the descriptive data on dog behaviour had been used to program an AI model, it would be more likely to issue severe punishments. These inaccuracies could be a real-world concern. For instance, if a descriptive model is used to predict whether a person may commit the same crime more than once, it may result in longer criminal sentences. 刷阅读理解 28 The researchers advocate increased data transparency （透明度） to understand how data is collected. And their future work is to investigate the impact of having experts, such as lawyers and doctors, participate in data entry to see if it will lead to the same result.“Generally, normative decisions tend to be more lenient （宽容的）,” says lead author Aparna Balagopalan.“Perhaps the way people think about violations differs from how they think about descriptive data.” 刷阅读理解 29 1.What can we learn about descriptive data?( ) A A.They’re usually used to train AI. B.They lead to more accurate judgements. C.They consist of causes of a situation. D.They’re gathered to identify rule violations. 解析 细节理解题。根据第二段中的However, data used to train machine-learning models are typically labelled descriptively—meaning people label the factual features of a situation, and AI determines whether a code has been broken.可知，用于训练机器学习模型的数据通常是描述性数据。故选A项。 【语篇导读】本文是一篇说明文，主要介绍了人们通常认为计算机会作出公平公正的判断，但来自麻省理工学院的研究发现，人工智能模型会作出比人类更严厉的判断。 刷阅读理解 30 2.Why does the author mention the example in Paragraph 4?( ) B A.To present a fact. B.To highlight a problem. C.To introduce a topic. D.To oppose an opinion. 解析 推理判断题。根据上文介绍的实验过程以及第四段内容可知，实验发现参与者使用描述性方法识别出违规的可能性更高。如果将关于狗的行为的描述性数据用于人工智能模型编程，则人工智能更有可能作出严厉的惩罚。这些不准确之处在现实世界中会是一个令人担忧的问题。接着举例以强调这一问题的严重性。由此可推知，作者在第四段提到这个例子是为了强调这个问题。故选B项。 刷阅读理解 31 3.What do the researchers plan to do?( ) D A.Use more normative data. B.Seek advice on data entry from experts. C.Find new ways to gather data. D.Conduct studies with professional labellers. 解析 细节理解题。根据最后一段中的And their future work is to investigate the impact of having experts, such as lawyers and doctors, participate in data entry to see if it will lead to the same result.可知，研究者们接下来的工作是研究让专业人士参与数据录入的影响，以弄清专业人员的参与是否会产生相同的结果。由此可知，研究者们打算通过让专业人员担任数据标记员开展研究。故选D项。 刷阅读理解 32 4.Which of the following can be the best title for the text?( ) C A.AI: Rule Defender or Breaker? B.Data Set: Decisive Part of AI C.AI Judge: Stricter Than Humans D.Better Data: Descriptive or Normative? 解析 主旨大意题。阅读全文可知，文章第一段点明了主题——研究发现人工智能是比人类更为严苛的法官；第二、三段介绍了研究的手段和过程；第四段介绍研究结果以及发现的问题；第五段是未来研究方向。故最适合概括本篇文章的标题是“人工智能法官:比人类更严格”。故选C项。 刷阅读理解 33 【方法总结】如何选择说明文的最佳标题 文章标题可帮助读者迅速推测出整篇文章的主要内容，抓住文章的中心，把握作者的观点和意图。它的特点是：（1）短小精悍；（2）涵盖性强，一般要求能覆盖全文，其涵盖的范围既不能太大，也不能太小；（3）精确性强；（4）能吸引读者的眼球，引起读者的阅读兴趣。 解答这类题目时，可结合文体判断。说明文是文体特征很明显的一类文本，在说明文中，作者通常会在文章的开头阐明文章的主旨或写作目的，或是在结尾处总结文章内容。 选择说明文标题时应做到：（1）先看文章的首段与尾段，找到文章的主旨句，定位关键信息；（2）再阅读每个段落，尤其是段落的首句和尾句，找到每个段落的主旨句，判断段落大意，从而判断出文章结构（总—分、总—分—总、分—总）；（3）根据以上信息对比四个选项，排除概括不全、概括范围过大等的干扰项，即可得出正确答案。 刷阅读理解 34 核心词汇 1.ban vt.禁止；取缔 n.禁止；禁令 2.commit vt.犯（罪）；做（错事）；承诺 vi.全心全意投入 熟词生义 issue 熟义：n.议题；争论的问题；（杂志或报纸的）期 生义：vt.发出（命令；警告等）；颁布；发表（声明） 刷阅读理解 35 Modern inventions have speeded up people’s lives amazingly.
