46. What do we learn from research in human-vehicle interaction?
- A. Automatic driving systems are by no means immune to errors.
- B. Driverless vehicles are likely to be misused by some people.
- C. Self-driving car manufacturers are not aware of the legal matters involved.
- D. There is a long way to go before humans can interact with driverless vehicles.
答案：A
答案句：Research in human-vehicle interaction has shown even systems designed to automate driving are far from being error-proof.
参考译文：人机交互研究表明，即使是设计用于自动驾驶的系统也远非无懈可击。
定位线索：题干“research in human-vehicle interaction”→答案句首句“Research in human-vehicle interaction”；文中“far from being error-proof”对应选项A“by no means immune to errors”。
解析：题干问从人机交互研究中得知什么，答案句直接指出自动驾驶系统“far from being error-proof”，即远非无差错，与选项A“by no means immune to errors”（绝非免于错误）同义。选项B“被滥用”文中虽提及但非研究结论；C“制造商不知法律问题”无中生有；D“人类与无人驾驶车互动之路漫长”是文章结尾观点，非研究结论。
47. What is the problem with requiring buyers to sign end-user license agreements?
- A. End users, young and old alike, find the terms complex to interpret.
- B. Most end users sign them without bothering to read the terms.
- C. Many people are often confused by the wording of the terms.
- D. Most end users do not understand the terms after reading them through.
答案：B
答案句：Further, most end users don't read EULAs. A 2017 study shows 91 percent of people agree to them without reading. Among young people, 97 percent agree without reviewing the terms.
参考译文：此外，大多数最终用户不阅读EULA。2017年的一项研究显示，91%的人未阅读就同意。在年轻人中，97%的人未审阅条款就同意。
定位线索：题干“problem with requiring buyers to sign end-user license agreements”→答案句“most end users don't read EULAs”；文中“91 percent...without reading”对应选项B“Most end users sign them without bothering to read”。
解析：题干问要求买家签署EULA的问题，答案句明确指出大多数最终用户不阅读EULA，且引用数据91%和97%的人未阅读就同意，与选项B“大多数最终用户不读条款就签署”直接对应。选项A“条款复杂难解”、C“被措辞困惑”、D“读后不理解”均无原文依据。
48. What would drivers do when they suffer from “warning fatigue”?
- A. Waste no time keeping the car moving.
- B. Rest a while to avoid fatigue driving.
- C. Take no action despite repeated warnings.
- D. Take note of the message though fatigued.
答案：C
答案句：For example, a driver, annoyed after receiving continuous warnings, could decide to just ignore the message.
参考译文：例如，司机在收到连续警告后感到厌烦，可能会决定直接忽略该信息。
定位线索：题干“warning fatigue”→答案句“continuous warnings”；文中“ignore the message”对应选项C“Take no action despite repeated warnings”。
解析：题干问司机遭受“警告疲劳”时会怎样，答案句举例说明司机在连续警告后感到厌烦，可能“ignore the message”（忽略信息），即尽管反复警告也不采取行动，对应选项C。选项A“保持车辆移动”、B“休息避免疲劳”、D“尽管疲劳仍注意信息”均与原文“忽略”相反或无中生有。
50. What should be done to help drivers fully understand system capabilities and limitations?
- A. Training them to be experts in vehicle automation.
- B. Familiarizing them with the systems through training.
- C. Broadening their knowledge of accident-prevention mechanisms.
- D. Facilitating their access to the information provided by the seller.
答案：B
答案句：Driver training for self-driving vehicles can help ensure that drivers fully understand system capabilities and limitations.
参考译文：针对自动驾驶车辆的驾驶员培训有助于确保驾驶员充分理解系统的能力和局限性。
定位线索：题干“help drivers fully understand system capabilities and limitations”→答案句“ensure that drivers fully understand system capabilities and limitations”；文中“Driver training”对应选项B“Familiarizing them with the systems through training”。
解析：题干问如何帮助驾驶员充分理解系统能力和局限，答案句明确指出“Driver training”（驾驶员培训）可以实现这一目标，与选项B“通过培训使他们熟悉系统”对应。选项A“培训成专家”程度过重；C“事故预防机制”无中生有；D“获取卖方信息”是文中否定的方法，答非所问。
