According to a recent survey released earlier this month, 8 percent of drivers, or 1.2 million people, are using handheld or hands-free cell phones at any given time during daylight hours. That's double the number from just 4 years ago. What does that mean for your safety? More and more studies are telling us that, whether it's handheld or hands-free, cell phone conversations are distracting to drivers. 2,600 deaths and more than 300,000 collisions each year are related to cell phones. Some 40 states are talking about joining New York, New Jersey and Washington, D. C. in banning hand-held cell phones in vehicles. Of all the distracting things we do in our cars, cell phones aren't the worst. The most prevalent distracting events were conversations, eating and drinking, and dealing with things that had dropped in the car. Researchers have found that dialing takes your eyes off the road and talking on the phone takes your mind out of the car and into the conversation. University of Utah studies show that cell phones, even while using a headset, have a real effect on reaction time. Some even compare it to driving while drunk. If you thought your hands-free cell phone is safer because both hands are free to grip the wheel, think again. Hands-free units can be less safe, because it leads to longer conversations and more mental distraction. What we can conclude from the passage is that ________.A. hand-held cell phones are banned in most of U.S. statesB. hands-free cell phones can be less safeC. hand-held cell phones can be more dangerousD. answering cell phones is better than driving while drunk

题目解答

答案

根据文章内容，我们可以得出以下解析： 1. **背景信息**： - 最近的一项调查显示，8%的司机（约120万人）在白天任何时候都在使用手持或免提手机。 - 这个数字是四年前的两倍。 - 每年有2,600人死亡和超过300,000起碰撞事故与手机使用有关。 - 许多州正在考虑禁止在车辆中使用手持手机。 2. **手机使用的影响**： - 无论是手持还是免提手机，通话都会分散司机的注意力。 - 拨号会让人的眼睛离开道路，通话会让人的心思集中在对话上。 - 研究显示，使用手机（即使使用耳机）会显著影响反应时间，甚至有人将其比作酒后驾驶。 3. **其他分心行为**： - 在车内最普遍的分心行为包括对话、吃喝和处理掉在车内的物品。 - 免提手机并不一定更安全，因为长时间的对话会导致更多的精神分心。 4. **选项分析**： - **A. 手持手机在大多数美国州被禁止**：文章提到一些州正在考虑禁止手持手机，但并没有说大多数州已经禁止。 - **B. 免提手机可能更不安全**：文章提到免提手机可能导致更长的对话和更多的精神分心，因此可能更不安全。 - **C. 手持手机可能更危险**：文章没有明确比较手持和免提手机的危险性，只是提到两者都会分散注意力。 - **D. 接听手机比酒后驾驶更安全**：文章提到使用手机的影响类似于酒后驾驶，但没有说接听手机比酒后驾驶更安全。 综上所述，最符合文章内容的结论是： **B. 免提手机可能更不安全**

解析

考查要点：本题考查根据文章内容推断正确结论的能力，需要结合细节信息和隐含逻辑进行推理。
解题核心：抓住文章中关于“免提手机安全性”的关键描述，对比选项，排除干扰项。
破题关键：注意文章中“hands-free units can be less safe”这一核心结论，以及“longer conversations”和“mental distraction”的关联。

选项分析：

  1. 选项A：文章提到“40 states are talking about joining”禁用手持手机，但未说明“most states”已禁止，属于过度推断。
  2. 选项B：文章明确指出“hands-free units can be less safe”，因为“longer conversations”导致“mental distraction”，与文章内容完全一致。
  3. 选项C：文章未直接比较手持与免提手机的危险性，仅说明两者均会分心，无法支持此结论。
  4. 选项D：文章将手机使用的影响比作“driving while drunk”，但未说明“answering phones”更安全，属于曲解文意。

结论：唯一与文章内容完全匹配的选项是B。
