别在使用GPS了——老夏考研每日一题（21）

​我们的生活中，广泛使用着GPS，怎么就会损害（impair）大脑呢？今天文章的作者是一位写作有关科技和伦理题材的记者（a journalist who writes about science, technology and ethics）。

老夏考研“每日一题”今天内容选材于“华盛顿邮报”文章。文章标题为“Ditch the GPS. It’s ruining your brain.”（放弃全球定位系统GPS。它正毁了你的大脑）。

今天给的是个阅读理解单选题。请大家先做题吧 ......

【题目】Bohbot’s remarks seem to suggest that less use of GPS   

[A] benefits the brain a lot.

[B]prevents chronic diseases.

[C] helps create good habits.

[D] will make us get lost.

【试题】

①What isn’t known is the effect of GPS use on hippocampal function when employed daily over long periods of time. ②Javadi said the conclusions he draws from recent studies is that “when people use tools such as GPS, they tend to engage less with navigation. ③Therefore, brain area responsible for navigation is less used, and consequently their brain areas involved in navigation tend to shrink. ④“If we are paying attention to our environment, we are stimulating our hippocampus, and a bigger hippocampus seems to be protective against Alzheimer’s disease,” Bohbot told me in an email. ⑤“When we get lost, it activates the hippocampus, it gets us completely out of the habit mode.” ⑥Done safely, getting lost could be a good thing.

【参考译文】

①What isn’t known is the effect of GPS use on hippocampal function when employed daily over long periods of time.目前还不清楚的是，如果每天长时间使用GPS，会对海马组织的功能产生什么影响。 

②Javadi said the conclusions he draws from recent studies is that “when people use tools such as GPS, they tend to engage less with navigation. Javadi说，他从最近的研究中得出的结论是，“当人们使用GPS等工具时，他们往往较少参与导航。”

③Therefore, brain area responsible for navigation is less used, and consequently their brain areas involved in navigation tend to shrink. 因此，负责导航的大脑区域被使用得更少，因此，他们的大脑中涉及导航的区域往往会缩小。

④“If we are paying attention to our environment, we are stimulating our hippocampus, and a bigger hippocampus seems to be protective against Alzheimer’s disease,” Bohbot told me in an email. Bohbot在一封电子邮件中告诉我,“如果我们关注环境，我们就会刺激海马体，一个更大的海马体似乎可以预防老年痴呆症”。

⑤“When we get lost, it activates the hippocampus, it gets us completely out of the habit mode.”“当我们迷路时，就会激活海马体，让我们完全摆脱习惯模式。” 

⑥Done safely, getting lost could be a good thing. 如果做得安全，迷路可能是件好事。
