[解析]
(1)D.情感态度题。根据第一段中的We are finally waking up to the severity of the problem by supporting and developing a group of tools,apps and approaches intended to prevent scammers from getting through.Unfortunately,it's too little,too late.By the time these "solutions"(解决方案) become widely available,scammers will have moved onto cleverer means.可知,我们认识到了问题的严重性,支持和开发了旨在防止欺诈者通过的工具、应用程序和方法,。不幸的是,我们的努力太少了,也太晚了。在这些"解决方案"被广泛使用的时候,骗子将转移到更巧妙的手段上。由此推知,作者认为这些"解决办法"对于解决问题起不了什么作用,因此作者感到很"失望"。结合选项:A.Panicked.惊慌的;B.Confused.困惑的;C.Embarrassed.尴尬的;D.Disappointed.失望的。故选D。
(2)A.细节理解题。根据第三段中的The reason that robocalls are a headache has less to do with amount than precision.A decade of data breaches(数据侵入) of personal information has led to a situation where scammers can easily learn your mother's name,and far more.Armed with this knowledge,they're able to carry out individually targeted campaigns to cheat people.This means,for example,that a scammer could call you from what looks to be a familiar number and talk to you using a voice that sounds exactly like your bank teller's,tricking you into "confirming" your address,mother's name,and card number.可知,机器人通话之所以令人头痛,与其说与数量有关,不如说与精确度有关。长达十年的个人信息泄露已经导致了这样一种情况:骗子可以轻易地知道你母亲的名字,甚至更多。有了这些知识,他们就能够开展有针对性的活动来欺骗人们。根据这些可知,利用这种新的技术,欺诈者们可以精确的确定他们行骗的目标。故选A。
(3)B.推理判断题。根据第二段最后一句At this year's I/O Conference,a company showed a new voice technology able to produce such a convincing human﹣sounding voice that it was able to speak to a receptionist and book a reservation without detection.可知,这项语音技术可以产生一个听起来和人类非常相似的声音,它可以和接待员进行交谈,进行预订。由此可知,这项新技术有其好的方面。根据第三段的叙述可知,欺诈者们可以利用这项新技术来进行欺诈行为。由此推知,这项新技术既可以发挥好的作用,也可能为坏人所利用,产生不好的影响,因此可以说它是一把双刃剑。故选B。
(4)C.标题判断题。文章在第一段提到了自助语音电话带给人们的危害,紧接下来的两段又进一步阐述这类电话带给人们危害的原因,并在倒数第二段阐述了减轻相关危害的方案,尾段最终提出信任度是很难获得又很容易失去的东西,并且,由此涉及的相关问题也会越来越难以解决。可知整篇文章都是在逐步阐述自助语音电话愈加危险的状况,所以C选项:为什么语音电话会变得更危险?最为题目最合适,故选C。
