本文是一篇博客，属于新媒体语篇。此类文章一般不拘泥于形式，内容时代感强，侧重互动性，语言则更注重个性化。文章在行文方式上虽然灵活多变，但通常会围绕一个中心展开或由一条线索串起。如本文按时间顺序展开，通过时间关键词then the day came、 at that very moment、 the first day、 at first、 then、 by the end of the week等将全文串联起来，层层递进地描述了作者由手机迷到停用手机之后的一系列变化，通过对比作者的前后变化，督促读者适度使用手机，把时间用在更有意义的事情上，多去感受真实世界中丰富多彩的生活。
(一)赏用词之妙　
1．My eyes were glued to the little screen whenever I walked down the street, had dinner with friends or lay in bed at night.
赏析：be glued to sth.生动形象地展现了作者对手机上瘾的情形。
2．At that very moment, I made up my mind to spend a whole week without my smartphone.
赏析：very用作形容词，表示“(特指人或事物)正是，恰好，同一的”。very moment强调“此时此刻”，表达了作者打算做出改变的决心。
3．The empty hours stretched out in front of me, and I felt disconnected from everyone and everything.
赏析：stretched out形象地写出了作者停用手机后的感受：时间变得缓慢，仿佛被拉长了一样。stretch out本义是“平躺；躺直；伸出，伸开(身体的某一部位)”。
4．Best of all, I began to appreciate the beauty in life with my own eyes, instead of through my smartphone camera.
赏析：作者在列举了自己远离手机后所进行的活动之后，用Best of all强调了要用自己的双眼而不是通过手机镜头去感受生活之美。
[提能训练]　(完成句子)
①She ______________________ the TV all evening and did nothing.
她整晚都盯着电视，什么都没做。
②You should make a plan ________________________________.
你们应该在学期一开始就制订一个计划。
③You can feel the rain _______________________________________.
如果你伸出手，就能感觉到在下雨。
④The beaches are very beautiful, but, ___________________________.
这片海滩很美，但最令人满意的是游客很少。
(二)赏句式之高　
1．...and that I could have done something more meaningful than just looking at a tiny screen all day.
赏析：could have done表示过去本可以做而实际上未做，表达出作者对过度使用手机的反思。
2．Head down, eyes on my smartphone, I stepped into the road and a car shot past, nearly knocking me off my feet!
赏析：独立主格结构Head down、 eyes on my smartphone简洁有力地描述了作者当时的形象：低着头，眼睛盯在手机上，搭配后面的简单句a car shot past及nearly引出的分词短语，画面清晰地呈现了当时惊险的一幕。
3．We had never felt closer to each other.
赏析：否定词never与比较级closer连用，突出强调了远离手机对作者的积极影响。
[提能训练]　(翻译句子)
①我本能够解决那个问题的，但我太紧张了。
________________________________________________________________________
________________________________________________________________________
②我从未经历过比今天更有趣的一天。
________________________________________________________________________
________________________________________________________________________
(三)赏描摹之韵　
1．(写作手法)I was used to checking the news and my friends' social media updates every few minutes, but now I did not know what to do with myself.
赏析：was used to ...but now ...采用了对比手法，叙述了作者停止使用手机后的不习惯。
2．(心理描写)I felt lost and anxious, as if I had missed something of value.Very soon, time slowed down.The empty hours stretched out in front of me, and I felt disconnected from everyone and everything.
赏析：第一句中用lost and anxious描写了作者心中的迷惘、不安，同时用as if引导的虚拟语气具象化了这种情感。随后的两句话中，作者接着把自己的感觉具象化：时间变得慢了下来，空虚的时光在自己面前拉长。这种写作手法带给读者强烈的代入感，如亲身所感。
3．(景物描写)The details of the scene were revealed in front of me: the soft sunlight, a bird singing from a high tree branch, the rich and earthy smell of the soil after the rain.
赏析：作者以工笔画的方式，在我们面前细致入微地描绘了一幅安详愉悦的画面：柔和的阳光、枝头歌唱的小鸟，以及雨后泥土的芬芳。

Ⅰ.阅读理解
A
The classroom, the bathroom, the outdoors — my smartphone is always in hand as if it were some magic self－defense tool capable of protecting me from all evil in the world.I also love my laptop, because it holds all of my writing and thoughts.Despite this love of technology, I know that there are times when I need to move away from these devices and truly communicate with others.
On occasion, I teach History Matters for a group of higher education managers.My goals for the class include a full discussion of historical themes and ideas.Because I want students to thoroughly study the materials and exchange their ideas in the classroom, I have a rule — no laptop, phones, etc.When students were told my rule in advance, some of them were not happy.
Most students assume that my reasons for this rule include unpleasant experiences with students misusing technology.There's a bit of truth to that.Some assume that I am anti－technology.There's no truth in that at all.I love technology and try to keep up with it, so I can relate to my students.The real reason is that I think there are very few places where we can have deep conversations and truly engage complex ideas.Interruptions by technology often break concentration and allow for too much dependence on outside information for ideas.I want students to dig deep within themselves for inspiration.I want them to think differently and make connections between the course materials and the class discussion.
I've been teaching my history class this way for many years.The evaluations reflect student satisfaction with the environment that I create.Students realize that with deep conversation and challenge, they learn at a level that helps them keep course materials beyond the classroom.
I'm not saying that I won't ever change my mind about technology use in my history class, but until I hear a really good reason for the change, I'm sticking to my plan.A few hours of technology－free dialogue is just too sweet to give up.
语篇解读：本文是一篇夹叙夹议文。作者在课堂上禁止学生使用电子产品，因为它们会影响深入交流和学生独立思考的能力。
1．What upset some students most at the beginning
A．The topics for class discussions.
B．The requirements for idea exchange.
C．The materials chosen for the course.
D．The ban on electronic devices in class.
解析：细节理解题。根据第二段最后两句可知，作者希望学生们在课堂上能够深入学习材料并相互交流，所以禁止学生在课上使用笔记本电脑、手机等，这个禁止使用电子产品的规定让一些学生不高兴。
√
2．Why are the students asked to give up technology in class
A．To push them to be more involved.
B．To make connections with information.
C．To explore their potentials to study better.
D．To introduce them to more complex themes.
解析：细节理解题。根据第三段最后四句可知，作者认为电子产品的使用会破坏学生的注意力，让学生产生依赖性；禁止这些电子产品，可以促使学生独立思考，更好地投入到课程材料和课堂讨论中。
√
3．What can be inferred about the author's classes
A．They are well received and highly assessed.
B．The study environment is far from satisfactory.
C．They show his attitude against high technology.
D．The managers are promoted by attending the classes.
解析：推理判断题。根据第四段中“The evaluations reflect student satisfaction with the environment that I create.”可知，作者的历史课受学生欢迎，学生的满意度很高。
√
4．What message does the author really want to convey
A．He will stick to this practice until he changes for a new job.
B．Technology is an effective way to relate teachers to students.
C．Unpleasant experiences can be the beginning of some new rules.
D．A few hours of technology－free dialogue will harvest a lot.
解析：推理判断题。根据最后一段可知，没有真正好的理由作者不会改变课上禁止使用电子产品的想法，因为无技术产品介入的相互交流效果特别好，能让人收获很多。
√
B
Sometimes a book comes along that isn't just “interesting” or “well done” — it's a book where it seems like the author looked into your brain and wrote a book specifically for you.A book like that for me was released last week.It's called 100 Things We've Lost to the Internet, written by editor Pamela Paul.
Paul lists 100 things we used to do that the Internet has either changed or taken over completely: writing letters, printing newspapers, the joys of being bored, and not having all the knowledge in the world in your pocket.
As I often accumulate random knowledge, certain entries on the list — Being the Only One, Figuring Out Who That Actor Is — hit me where I live; remembering detailed facts is no longer nearly as impressive when everyone has the capability to find the answer in seconds.
On and on the list goes, with every minor shift adding to the pile.What this book does so well is illustrate the growth of that pile; while any individual item might be no big deal, the collected set is significant.It's a list of ways in which the world now is different from the world then.
Obviously, Paul isn't saying that everything back then was better.Time marches on, after all, and it's tough to argue against the many benefits that the Internet has brought into our lives.But that isn't really the point.It's not about whether it used to be better.It's that it used to be different.
100 Things We've Lost to the Internet is a fun read for those of us who share some of Paul's memories and experience.We remember what it was like and we like to remember.The landscape has shifted, and no doubt it will shift again as technology's advancement continues apace (高速地)．This book serves as a reminder of the simple truth that when gains are made, sometimes something is lost.
语篇解读：本文是一篇说明文。文章介绍了一本名叫《被网络夺走的100种事物》的好书。
5．What is the purpose of the text
A．To review and recommend a good read.
B．To comment on the effect of the Internet.
C．To argue for the viewpoint of a new book.
D．To urge the readers to value what they have.
解析：写作意图题。根据全文内容尤其是第一段的描述可知，作者是在评论一本好书。后续的段落作者介绍了此书，故本文的写作目的是对一本好读物的评论和推荐。
√
6．Which might be entries on Paul's list
A．Maps and Eye Contact.
B．E－pay and Compact Disks.
C．Postcards and Homeschooling.
D．Photos and Washing Machines.
解析：推理判断题。根据第二段第一句中的“Paul lists 100 ...taken over completely”可知，Paul所列的100种事物是我们过去常做的，但被现在的网络改变或完全夺走了，故A项《地图和目光交流》可能会进入Paul的书单中。
√
7．What does the underlined part “hit me where I live” in paragraph 3 mean
A．Prove what I'm good at.
B．Introduce how I grew up.
C．Describe the place I live in.
D．Speak out what is on my mind.
√
解析：句意理解题。根据第一段中的“it's a book ...for you”和第三段中的“As I often accumulate ...hit me where I live”可知，作者认为一本好书的作者似乎就在洞察你的内心，由于作者经常积累各种随机的知识，故入选该书的某些事物吸引了作者；由此可推知，Being the Only One, Figuring Out Who That Actor Is应该是说出了作者的心声。故D项与画线部分意思相近。
8．What conclusion has the author drawn after reading Paul's book
A．Things in the past are better.
B．There're no gains without pains.
C．The Internet is a double－edged sword.
D．Technology is constantly changing the world.
解析：推理判断题。 根据最后一段中的“This book serves as a reminder of the simple truth that when gains are made, sometimes something is lost.”可知，这本书提醒了我们一个简单真相：当我们取得一些收获时，有时也会失去一些东西。
√
C
Wi－Fi has become an integral part of our fast－paced everyday lives.Thanks to Wi－Fi, we no longer have to be restricted to the Internet with cables.But have you ever stopped to wonder how it works
Wi－Fi uses radio waves to transmit information between your device and a router (路由器) via frequencies.Two radio－wave frequencies can be used, depending on the amount of data being sent: 2.4 gigahertz (千赫兹) and 5 gigahertz.What does that mean, though Well, a hertz is just a measurement of frequency.For example, let's say you're sitting on a beach, watching the waves crash to shore.If you measured the time between each wave crash, you'd be measuring the frequency of the waves.One hertz is a frequency of one wave per second.One gigahertz, on the other hand, is one billion waves per second.The higher the frequency, the greater the amount of data transmitted per second.
The two Wi－Fi frequencies are split into multiple channels so as to prevent high traffic and interference.When it comes to sharing the data across these channels, well, that's when the magic computer science happens.The first step in the process is initiated by you.When you access the Internet on your device, it transforms the information you've requested into binary (二进制) code, the language of computers.Everything computers do is based in binary code, a series of 1s and 0s.When you click on this article, your request is translated into a bunch of 1s and 0s.The frequencies travel across the radio channels mentioned earlier and are received by the Wi－Fi router that your
device is connected to.The router then transforms the frequencies back into binary code and translates the code into the Internet traffic that you requested, and the router receives that data through a hardwired Internet cable.The process repeats itself until you have loaded this article — or anything that requires the Internet.
语篇解读：本文是一篇说明文。文章主要介绍了Wi－Fi的工作原理。
9．What is the author's attitude to the Wi－Fi access
A．Favorable.　　　　　　 B．Tolerant.
C．Doubtful. D．Unclear.
解析：观点态度题。根据第一段第一、二句可知，作者对于Wi－Fi的态度是赞许的。
√
10．Why does the author mention “sitting on a beach” in paragraph 2
A．To make a prediction.
B．To clarify a concept.
C．To present a fact.
D．To offer a reason.
解析：推理判断题。根据画线部分上句可知，作者举坐在沙滩上(sitting on a beach)的例子是为了帮助大家理解赫兹这个概念。
√
11．What is the focus of the last paragraph
A．The significance of measuring frequency.
B．The method of transmitting information.
C．The function of translating binary code.
D．The principle of sharing data.
解析：段落大意题。根据最后一段的内容可知，本段主要是在介绍共享数据的原理。
√
12．What can be a suitable title for the text
A．When Does Wi－Fi Exist
B．What Does Wi－Fi Transmit
C．How Does Wi－Fi Work
D．Why Does Wi－Fi Matter
解析：标题归纳题。根据第一段最后两句并结合全文内容可知，本文主要是在介绍Wi－Fi是如何工作的。故C项适合作文章标题。
√
Ⅱ.阅读七选五
Five Ways to Stop Wasting Time Online
Here are five ways you can use to improve your concentration online.
Track your productivity.If you track your productivity at your computer, you might be surprised at what you find. __13__ I recommend that you use a free time tracking software to do it.
Never just browse (浏览信息) to start.One pattern I've noticed is that many people have tendencies that right after school, after work or coming home from dinner they power up their computers and just browse.Don't do that.Don't do it just to see what's new. __14__ Break the habit — you don't have to always be productive, but at least be aware and don't let the time be wasted.
__15__ Research, as well as personal experience, has shown that taking breaks can improve your effectiveness.I recommend a break every 20 to 30 minutes.Personally, I like to do simple yoga stretches or take a quick walk.
Power down.When I'm trying to focus on a task, I turn off my cell phones, computer and TV.Pick the electronic device that needs your focus. __16__ I go a step further and lock my computer every time I get up.I don't take my breaks at my computer: I separate my work space from my rest space.
Close your browser.Similar to the previous item, stop leaving your web browser open when you're trying to work.Remove your temptation by closing the web browser.However, you may want to browse websites. __17__
A．Always begin with a purpose.
B．Use that to complete your task.
C．Don't take your breaks at your computer.
D．But you have to make the calm decision to open it.
E．Do something different to relax yourself at fixed periods.
F．You need to make sure you begin effectively when you first sit down to work.
G．In an 8－hour day, how much time do you spend on emails, chatting or surfing the web
语篇解读：本文是一篇说明文。文章介绍了停止浪费网上时间、提高工作效率的五种方法。
13．解析：选G　根据空前一句可知，如果你跟踪一下自己在电脑上的工作效率，你可能会惊讶于自己的发现，而G项“在每天的8个小时中，你在处理电子邮件、聊天或者浏览网页上花了多少时间？”承接上文，说明了时间都花在了哪里，符合语境。
14．解析：选A　根据空前一句可知，不要只是打开电脑浏览网页上的更新内容，空后一句则提到要戒掉这一习惯。故A项“总是有目的地开始”承上启下，符合语境。
15．解析：选E　根据空后两句可知，要定期做一些活动来休息一下。故E项“要定期做不同的事情放松自己”引出下文，符合语境。
16．解析：选B　空前两句建议我们关闭其他电子设备，只打开需要用的。故B项“使用该设备去完成你的任务”承接上文，符合语境。
17．解析：选D　作者在本段主要建议工作时关闭浏览器，空前一句提到你可能想浏览网站。故D项“那么你必须要做出冷静的决定来打开它”承接上文，符合语境。UNIT 3　课时检测(五)　“Extended reading”的课文习读环节

Sometimes a book comes along that isn't just “interesting” or “well done” — it's a book where it seems like the author looked into your brain and wrote a book specifically for you.A book like that for me was released last week.It's called 100 Things We've Lost to the Internet, written by editor Pamela Paul.
Paul lists 100 things we used to do that the Internet has either changed or taken over completely: writing letters, printing newspapers, the joys of being bored, and not having all the knowledge in the world in your pocket.
As I often accumulate random knowledge, certain entries on the list — Being the Only One, Figuring Out Who That Actor Is — hit_me_where_I_live;_remembering detailed facts is no longer nearly as impressive when everyone has the capability to find the answer in seconds.
On and on the list goes, with every minor shift adding to the pile.What this book does so well is illustrate the growth of that pile; while any individual item might be no big deal, the collected set is significant.It's a list of ways in which the world now is different from the world then.
Obviously, Paul isn't saying that everything back then was better.Time marches on, after all, and it's tough to argue against the many benefits that the Internet has brought into our lives.But that isn't really the point.It's not about whether it used to be better.It's that it used to be different.
100 Things We've Lost to the Internet is a fun read for those of us who share some of Paul's memories and experience.We remember what it was like and we like to remember.The landscape has shifted, and no doubt it will shift again as technology's advancement continues apace (高速地)．This book serves as a reminder of the simple truth that when gains are made, sometimes something is lost.

A．Maps and Eye Contact.
B．E－pay and Compact Disks.
C．Postcards and Homeschooling.

Wi－Fi has become an integral part of our fast－paced everyday lives.Thanks to Wi－Fi, we no longer have to be restricted to the Internet with cables.But have you ever stopped to wonder how it works
Wi－Fi uses radio waves to transmit information between your device and a router (路由器) via frequencies.Two radio－wave frequencies can be used, depending on the amount of data being sent: 2.4 gigahertz (千赫兹) and 5 gigahertz.What does that mean, though Well, a hertz is just a measurement of frequency.For example, let's say you're sitting_on_a_beach,_watching the waves crash to shore.If you measured the time between each wave crash, you'd be measuring the frequency of the waves.One hertz is a frequency of one wave per second.One gigahertz, on the other hand, is one billion waves per second.The higher the frequency, the greater the amount of data transmitted per second.
The two Wi－Fi frequencies are split into multiple channels so as to prevent high traffic and interference.When it comes to sharing the data across these channels, well, that's when the magic computer science happens.The first step in the process is initiated by you.When you access the Internet on your device, it transforms the information you've requested into binary (二进制) code, the language of computers.Everything computers do is based in binary code, a series of 1s and 0s.When you click on this article, your request is translated into a bunch of 1s and 0s.The frequencies travel across the radio channels mentioned earlier and are received by the Wi－Fi router that your device is connected to.The router then transforms the frequencies back into binary code and translates the code into the Internet traffic that you requested, and the router receives that data through a hardwired Internet cable.The process repeats itself until you have loaded this article — or anything that requires the Internet.
9．What is the author's attitude to the Wi－Fi access
A．Favorable.　　　　　　 B．Tolerant.
C．Doubtful. D．Unclear.
10．Why does the author mention “sitting on a beach” in paragraph 2
A．To make a prediction.
B．To clarify a concept.
C．To present a fact.
D．To offer a reason.
11．What is the focus of the last paragraph
A．The significance of measuring frequency.
B．The method of transmitting information.
C．The function of translating binary code.
D．The principle of sharing data.
12．What can be a suitable title for the text
A．When Does Wi－Fi Exist
B．What Does Wi－Fi Transmit
C．How Does Wi－Fi Work
D．Why Does Wi－Fi Matter

Five Ways to Stop Wasting Time Online
Here are five ways you can use to improve your concentration online.
Track your productivity.If you track your productivity at your computer, you might be surprised at what you find.__13__ I recommend that you use a free time tracking software to do it.
Never just browse (浏览信息) to start.One pattern I've noticed is that many people have tendencies that right after school, after work or coming home from dinner they power up their computers and just browse.Don't do that.Don't do it just to see what's new.__14__ Break the habit — you don't have to always be productive, but at least be aware and don't let the time be wasted.
__15__ Research, as well as personal experience, has shown that taking breaks can improve your effectiveness.I recommend a break every 20 to 30 minutes.Personally, I like to do simple yoga stretches or take a quick walk.
Power down.When I'm trying to focus on a task, I turn off my cell phones, computer and TV.Pick the electronic device that needs your focus.__16__ I go a step further and lock my computer every time I get up.I don't take my breaks at my computer: I separate my work space from my rest space.
Close your browser.Similar to the previous item, stop leaving your web browser open when you're trying to work.Remove your temptation by closing the web browser.However, you may want to browse websites.__17__
A．Always begin with a purpose.
B．Use that to complete your task.
C．Don't take your breaks at your computer.
D．But you have to make the calm decision to open it.
E．Do something different to relax yourself at fixed periods.
F．You need to make sure you begin effectively when you first sit down to work.
G．In an 8－hour day, how much time do you spend on emails, chatting or surfing the web
