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第一段The Alpha Go program’s victory is an example of how smart computers have become.该句为段落中央句，阿尔法狗这一科研项目的成功，是打算机变得聪明和智能化的一个例证。
smart同义更换intelligent，故D选项为本题精确答案。

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、权衡得失落、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，并且这样会使搭客陷入危险，在这样两难的选择中，如何权衡得失落，做出最合理的行为。
以是该题选择B选项。

解析：根据关键词bigger challenge回定亲位至文章第3段Teaching ethics to a machine even more intelligent than we are will be the bigger challenge.使得机器人具有道德判断意识乃至比人类更加智能，这或将成为人类所面临的更大的寻衅。
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迁移转变处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辞吐。
可见泰勒不能区分善恶与好坏。
故此题A选项为精确选项。

55. What does Eric Schmidt think of artificial intelligence?

C.It will prove to be an asset to human beings.
