38. How does the author feel about the solutions to problem of robocalls?
- A. Panicked.
- B. Confused.
- C. Embarrassed.
- D. Disappointed.
答案：D
答案句：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.
参考译文：不幸的是，这些解决方案太少、太晚了。等到这些“解决方案”广泛可用时，骗子们已经转向更聪明的手段。
定位线索：题干“How does the author feel about the solutions”→答案句“Unfortunately, it’s too little, too late”中“Unfortunately”和“too little, too late”体现作者失望态度；文中“too little, too late”对应选项D“Disappointed”（失望的）。
解析：题干问作者对robocalls解决方案的感受。答案句直接说“Unfortunately, it’s too little, too late”，其中“Unfortunately”和“too little, too late”明确表达了作者认为解决方案不足且不及时，即失望。选项D“Disappointed”是对此的同义转述。选项A“Panicked”（恐慌的）、B“Confused”（困惑的）、C“Embarrassed”（尴尬的）均无原文依据，属于无中生有。
39. Taking advantage of the new technologies, scammer can______.
- A. aim at victims precisely
- B. damage databases easily
- C. start campaigns rapidly
- D. spread information widely
答案：A
答案句：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, ricking you into “confirming” your address, mother’s name, and card number.
参考译文：有了这些信息，他们能够开展针对个人的诈骗活动。这意味着，例如，骗子可以用看起来熟悉的号码给你打电话，用听起来和你的银行柜员一模一样的声音和你说话，诱骗你“确认”你的地址、母亲的名字和卡号。
定位线索：题干“Taking advantage of the new technologies, scammer can”→答案句“they’re able to carry out individually targeted campaigns”中“individually targeted”对应选项A“aim at victims precisely”（精准瞄准受害者）；文中“individually targeted”与选项“precisely”构成同义改写。
解析：题干问骗子利用新技术能做什么。答案句明确说“they’re able to carry out individually targeted campaigns”，即能进行针对个人的精准诈骗，对应选项A“aim at victims precisely”。选项B“damage databases easily”文中提到数据泄露但未说骗子能轻易破坏数据库，属于偷换概念；选项C“start campaigns rapidly”文中未提“rapidly”，属于无中生有；选项D“spread information widely”文中未提信息广泛传播，属于无中生有。
40. What does the passage imply?
- A. Honesty is the best policy.
- B. Technologies can be double-edited.
- C. There are more solutions than problems.
- D. Credibility holds the key to development.
答案：B
答案句：These developments are likely to make our current problems with robocalls much worse. … Voice manipulation technologies may weaken that gradually. … Credibility is hard to earn but easy to lose, and the problem is only going to harder from here on out.
参考译文：这些发展可能会使我们目前面临的robocalls问题更加严重。……语音处理技术可能会逐渐削弱这种信任。……信誉很难赢得但容易失去，而且问题只会越来越难解决。
定位线索：题干“What does the passage imply”→答案句“Voice manipulation technologies may weaken that gradually”和“Credibility is hard to earn but easy to lose”体现技术带来双重影响；文中“Voice manipulation technologies”对应选项B“Technologies can be double-edged”（技术是双刃剑）。
解析：题干问文章暗示什么。文章提到新技术能产生逼真声音，使诈骗更精准，但也可能用于正当用途，同时指出“Voice manipulation technologies may weaken that gradually”和“Credibility is hard to earn but easy to lose”，暗示技术既有好处也有坏处，即双刃剑，对应选项B。选项A“Honesty is the best policy”文中未提，属于无中生有；选项C“There are more solutions than problems”与原文“too little, too late”矛盾；选项D“Credibility holds the key to development”文中虽提信誉，但未说它是发展的关键，属于过度推断。
41. Which of the following would be the best title for the passage?
- A. Where the Problem of Robocalls Is Rooted
- B. Who Is to Blame for the Problem of Roboealls
- C. Why Robocalls Are About to Get More Dangerous
- D. How Robocalls Are Affecting the World of Technology
答案：C
答案句：The problem of robocalls has gotten so bad that many people now refuse to pick up calls from numbers they don’t know. By next year, half of the calls we receive will be scams(欺诈). … These developments are likely to make our current problems with robocalls much worse. … We need to deal with the insecure nature of our telecom networks.
参考译文：robocalls问题已经严重到许多人现在拒绝接听不熟悉号码的来电。到明年，我们接到的电话中将有一半是欺诈。……这些发展可能会使我们目前面临的robocalls问题更加严重。……我们需要处理电信网络的不安全性。
定位线索：题干“best title for the passage”→答案句“These developments are likely to make our current problems with robocalls much worse”概括了文章主旨；文中“make our current problems…much worse”对应选项C“Why Robocalls Are About to Get More Dangerous”（为什么robocalls将变得更危险）。
解析：题干问最佳标题。文章首段指出robocalls问题严重，第二段介绍新技术，第三段说明这些技术会使问题更严重，第四段提出应对措施，整体围绕“robocalls将变得更危险”展开，对应选项C。选项A“Where the Problem of Robocalls Is Rooted”只涉及问题根源，范围过窄；选项B“Who Is to Blame”文中未讨论责任归属，属于无中生有；选项D“How Robocalls Are Affecting the World of Technology”颠倒了因果关系，文中是技术影响robocalls，而非robocalls影响技术。
