总体来看2018年12月四级阅读理解真题保持了以往的水准，有生僻单词但是难度适中，出题思路也是常见的题型，今天文都四六级老师将12月英语四级阅读真题及答案：人工智能推送给大家。
51.What does the author want to show with the example of Alpha Go`s victory?
D.Computers can become highly intelligent.
解析：首先按照题文同序原则以及关键词定位到文章段The Alpha Go program’s victory is an example of how smart computers have become.该句为段落中心句，阿尔法狗这一科研项目的成功，是计算机变得聪明和智能化的一个例证。smart同义替换intelligent，故D选项为本题正确答案。
52. What does the author mean by AI machines acting ethically?
B.They weigh the gains and losses before reaching a decision.
解析：通过acting ethically定位至文章第二段，第二段写到Sometimes, however, they will face a choice between lives. Should the cars be programmed to avoid hitting a child running across the road, even if that will put their passengers at risk? 作者在该段发问，是否机器人在面临选择时，可以通过判断、权衡得失、做出合理性选择?并举例：人工智能无人驾驶车在路上行驶时，能否去避免撞到儿童，并且这样会使乘客陷入危险，在这样两难的选择中，如何权衡得失，做出最合理的行为。所以该题选择B选项。
53. What is said to be the bigger challenge facing humans in the AI age?
B.How to ensure that super-intelligent Al machines act ethically.
解析：根据关键词bigger challenge回文定位至文章第3段Teaching ethics to a machine even more intelligent than we are will be the bigger challenge.使得机器人具德判断意识甚至比人类更加智能，这或将成为人类所面临的更大的挑战。故B选项为正选。
54. What do we learn from Microsoft’s “chat bot” Taylor?
A.She could not distinguish good from bad.
解析：通过关键词“chat bot” Taylor可定位至文章第四段，尾句but转折处but some people were teaching Taylor racist ideas. When she started saying nice things about Hitler, Microsoft turned her off and deleted her ugliest messages.该句句意为：一些人教泰勒种族主义的思想，但她却表达了关于希特勒积极的言论。可见泰勒不能区分善恶与好坏。故此题A选项为正确选项。
55. What does Eric Schmidt think of artificial intelligence?
C.It will prove to be an asset to human beings.
解析：本题为态度题，通过专有名词Eric Schmidt定位至文章最后一段Eric Schmidt is one of the bosses of Google, which own Alpha Go. He thinks AI will be positive for humans. 说AI对人类是积极的，也就是说，可以作为人类的一种资产。故选择C。
由题可知，今年的四级阅读的选材和时下的热门话题和社会发展的趋势紧密相关。在选材语料上同样具有鲜活性、科学性和社会性。从阅读理解的难以程度来看，虽然是一片科学性比较强的科普类文章，但在本质上同样是在考查阅读理解基本的解题能力。在此，建议在今后备战四级阅读的各位考生，要以真题阅读为基础，逐步培养自己深度阅读理解的能力，学会总结解题思路和方法，进而在阅读理解这一项取得。
