Question

    As tech gets ever more clever, it opens possibilities - not just for business but for cybercriminals（网络罪犯）.Companies are being kept on their toes to find the most up-to-date security. 1. However, the real question is, "How can we use this securely?"

AIs may make it easier to attack company systems. They also give security experts new ways to detect problems and free them up from repetitive（重复的）work. 2.

AIs also provide new solutions for security operation centers. 3. This job used to be done by skilled analysts（分析师）. But machine learning can now spot 80 percent of false positives, leaving the analysts to work on the potentially harmful 20 percent.

AIs are very good at recognizing new things which are potentially a problem.4.They spot new threats because they've learned what looks normal and what doesn't. You have to accept you will be attacked and deal with it like an immune system would. The next step is to allow Al systems to take action in real time, so you have self-defending networks.5.

A.So they can focus their efforts where they are needed most.

B.This includes old and new tech working side by side.

C.They're a bit like the human immune system.

D.For example, it is very good at identifying misleading security alarms.

E.It's vital to have a right view of how technology is actually used.

F.Then you will have an Al reacting to attacks and you'll never even know it.

G.When they adopt new technology, they often ask themselves, "Is this secure?"

【解析】

这是一篇说明文。本文介绍了人工智能可以在不同领域帮助我们。例如：可以帮助检测出问题，让工程师不用做重复性的工作；检测出安全问题；甚至还可以检测出潜在的问题。

1.

考查上下文语境。前文提到“Companies are being kept on their toes to find the most up-to-date security.”公司不断寻求安全，G项紧接前文说公司在用新技术之前都会问 “这安全吗？”符合语境。故选G。

2.

考查上下文语境。前文提到“…free them up from repetitive（重复的）work.”人工智能把安全专家们从重复性的工作中解脱出来，A项“这样他们就可以把精力集中在最需要他们的地方”，符合语境。故选A。

3.

考查上下文语境。上文AIs also provide new solutions for security operation centers.说人工智能也为安全运营中心提供了新的解决方案。下文This job used to be done by skilled analysts说这项工作过去是由熟练的分析师来做的。该空承上启下，D项“例如，它非常擅长识别具有误导性的安全警报。”切题。故选D。

4.

考查上下文语境。上文AIs are very good at recognizing new things which are potentially a problem.说人工智能非常善于识别潜在的问题。下文They spot new threats because they've learned what looks normal and what doesn't.说它们发现新的威胁，因为它们知道什么看起来正常，什么不正常。该空承上启下 ，下文immune system是关键词, C项“它们有点像人类的免疫系统”符合语境。故选C。

5.

考查上下文语境。前文提到“The next step is to allow Al systems to take action in real time, so you have self-defending networks”（下一步是允许Al系统实时采取行动，这样就有了自我防御的网络。）F项“然后，在受到攻击时将会有一个AI式的反应，而你将永远都不会知道。”该空承接上文，故选F。
