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 realm. Yet with research into the impact 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 brainimaging studies in order to assess some of the leading hypothesis 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. Whats clear, however, is that the more time we spend online, the more we alter our cognitive function. 【注】realm n. 王国；领域；范围impact n. 冲击(力)，撞击，巨大 影响vt. 挤入，压紧hypothesis n. 假设，猜测，前提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 Listening and Speaking 基础知识 预习自检 .重点词汇 1blog n. 博客vi. 写博客blogger n. 博客作者；博主 2engine n. 引擎；发动机；火车头engineer n. 工程师engineering n. 工 程；工程学 3identity n. 身份；个性identify v. 认出，识别 4blog_post 博文；博客帖子 5search_engine (互联网上的)搜索引擎 6identity_card 身份证 7stream_movies_and_music 流(媒体)式播放电影和音乐 8more_than 超过；不仅仅是；非常 9chat_with_sb. 和某人聊天 10it_depends 看情况； 那得看情况； 这得看情况 .教材原句 1I _ (写博客文章) when I am online. 答案：write a blog post 2I _ (使用搜索引擎) when I am online. 答案：use a search engine 3A blog is _ (一篇在线日记) where you write about something youre interested in. 答案：an online diary 4_ (多少时间) do you spend online every day? 答案：How much time 5I _ (从不分享) the things that should be only mine. 答案：never share 6When you hear a word you dont know, _ (注意) the next sentence or two to see if there is a definition. 答案：pay attention to 7These are things only I should know _ (在网站或游戏 中) 答案：on website or in games 8I listen to music, _ (流媒体式播放视频), or look up information. 答案：stream videos 9I always keep things secret when I _ (上网) 答案：go online 10And so I use a nonsense name for my _ (网络身份) 答案：net identity 重点知识 合作探究 1blog n. 博客vi. 写博客(教材 P26) 归纳 拓展 (1)经常刷微博，你知道这些词用英语怎么说吗？ blog post 博文；博客帖子microblog 微博；fans/followers 粉丝； mutual following 互粉；forward 转发；comment, to leave a comment 评论；a Weibo update/post 一条微博；private message 私信；flood the screen 刷屏；submit 发布；refresh/reload 刷新；reply 回复； block this user/add to black list 拉黑；review and repost the Weibo 评 论并转发；unfollow 脱粉 (2)blogging v. 写博客(blog 的ing 形式) (3)blogger n. 写博客的人；博主 So far, Sina_MicroBlog has been leading the market in China. 到目前为止，中国微博市场仍是新浪微博占领先地位。 I was then able to quit my job and be a blogger and author full time. 后来，我得到机会辞去了之前的工作，成为了全职博客写稿人和作家。 I blog for MSN for example, a job that came about via Twitter. 例如，我为 MSN 撰写博客，这工作是通过 Twitter 得到的。 (1)单句语法填空 I need it for my _ (blog), my other writing, for keeping in touch with family and friends.

From computers to smartphones, a web of information is open to them. According to a new report, about three out of four kids aged 12 to 15 connect the Internet using a mobile device from time to time. Many younger kids are online too. Julian Zeitlinger, 9, from New Jersey, uses his computer to watch videos and play games. To keep him safe online, his parents monitorhis web use and discuss W1 Internet safety with him. “I ask my parents whether something is nice or bad， ” Julian says. Mobile devices offer more ways than ever to share personal information. The information can be dangerous in the wrong hands.A study found that 62% of children aged 8 to 17 have had an unpleasant online experience. Have you ever had to enter a parents email address when signing up for a P1 website? That safety measure is there because of the Childrens Online Privacy Protection Act (COPPA). The law says sites for kids under 13 cannot collect personal information, such as a phone number or full name, without a parents permission. W2 This July, the Federal Trade Commission (FTC) will update COPPA for the first time since the law was created in 1998 when there were no smart phones. The nature of the way kids get online has changed, FTC lawyer Phyllis Marcus said. When the changes take effect, COPPA will apply tomobile devices and newer P2 forms of advertising. It will expand what falls under “personal information” to include videos, photographs, and services that give users location. COPPA doesnt cover everything that can go wrong online. That is why kids and parents need to know what to look out for and to stop and think before sharing P3 information online. “There is a misunderstanding that if a site is following COPPA, it is totally safe， ” says privacy expert Shai Samet. He runs kidSAFE, which checks whether a site meets kidSAFE standards and is safe. “Its important that kids know how useful the Internet is but th
