Unit 3 The internet互联网给我们的工作和生活带来便捷，但它在改变我们生活的同时，也正在改变我们大脑的结构和功能。From gathering food to finding a mate and communicating with other members of society, many of the most basic human activities are now being carried out in the virtual realm①. Yet with research into the impact② of the Internet on brain function still in its infancy, an international team of researchers has compiled a review of everything we have learned so far about how digital life is altering our minds. Appearing in the journal World Psychiatry and authored by scientists from Oxford University, Harvard University, Western Sydney University, Kings College, and Manchester University, the review examines findings from a number of brain－imaging studies in order to assess some of the leading hypothesis③ regarding how the Internet may affect our brains. Though the findings are not intended to be taken as conclusive, evidence suggests that our online lifestyles are altering brain regions associated with attention, memory, and social skills.Whether the Internet is good or bad for our brains is not definitive. What's clear, however, is that the more time we spend online, the more we alter our cognitive function④.【注】 ① realm n. 王国；领域；范围 ② impact n. 冲击(力)，撞击，巨大影响 vt. 挤入，压紧 ③ hypothesis n. 假设，猜测，前提 ④ function n. 功能，函数，职务【立德树人】 有人说不论何时互联网都是一把双刃剑(doubleedged sword)，作为中学生我们要了解互联网的发展，要趋利避害，充分利用(make full use of)网络开阔视野，发展自己，造福社会。Section Ⅰ Listening and Speaking基础知识 预习自检Ⅰ.重点词汇1．blog n. 博客 vi. 写博客→blogger n. 博客作者；博主2．engine n. 引擎；发动机；火车头→engineer n. 工程师→engineering n. 工程；工程学3．identity n...
