11.After years of sales growth,major publishers reported a fall in their e-book sales for the first time this year,introducing new doubts about the potential of e-books in the publishing industry.Yet despite the increasing realization that digital and print can easily coexist in the market,the question of whether the e-book will"kill"the print book continues to surface.It doesn't matter if the intention is to predict or dismiss this possibility; the potential disappearance of the book does not stop to inspire our imagination.After television was invented,many claimed radio would die.But radio ended up surviving by finding new uses; people started listening in cars,during tram rides and on factory floors.The myth of the disappearing book isn't new,either.As early as 1894,there was guess that they'd be replaced by what we today call audiobooks.This happened again and again.Movies,radio,television,and smartphones-all conspired to destroy print books as a source of culture and entertainment.It is not by chance that the idea of the death of the book surfaces in moments of technological change.
We create emotional bonds with media as they become an integral part of our life.The emergence of a new technology-like e-readers-doesn't just in indicate economic and social change.It also causes us to adjust our relationship with something that has become an integral part of our day-to-day life.
The ones who still worry for the disappearance of print books may rest assured:Books have endured many technical revolutions and are in the best position to survive this one.Yet the myth of the disappearing medium will continue to provide an appealing narrative about both the power of technology and our dislike to change.Easy to remember and to spread,the story of the death of media reflects our excitement for the future,as well as our fear of losing parts of our intimate world一and finally,of ourselves.
33.What do people tend to believe according to the text?A
A.Print books will disappear in the end.
B.It is unwise to invest in e-books.
C.Digital and print will exist all the time.
D.The death of books is just an imagination.
34.What can we learn from the second paragraph?D
A.The forms of books change with new technology.
B.Books have a bright digital future actually.
C.Culture will disappear with the end of books.
D.The idea of book death follows technological changes.
35.What does the myth of disappearing books reflect?B
A.Our doubt about the power of technology.
B.Our fear of losing ourselves in society.
C.Our preference for new technology.
D.Our pleasure of experiencing technical revolutions.
分析 本文主要讲述了印刷书籍在现在社会的消失,同时也由它的消失引发一系列对自我的思考.
解答 33.A 细节题.根据文中内容,It doesn't matter if the intention is to predict or dismiss this possibility; the potential disappearance of the book does not stop to inspire our imagination.由此可知,书籍从我们生活中逐渐变少事实使得人们认为,印刷书最终会在世界上消失.结合选项,故选A
34.D 细节题.根据文中内容It is not by chance that the idea of the death of the book surfaces in moments of technological change.书籍的死亡书籍变少的事实并非偶然的告诉我们,这是科技变化的结果.结合选项,故选D
35.B 细节题.根据文中内容 Easy to remember and to spread,the story of the death of media reflects our excitement for the future,as well as our fear of losing parts of our intimate world一and finally,of ourselves.媒体的消失是很容易记住的事,反映出我们对于未来的兴奋,同时也反应出我们害怕失去亲密的世界甚至于丢失我们自己.结合选项,故选B

3D printing or additive manufacturing is a process of making three dimensional solid objects from a digital file.
The creation of a 3D printed object is achieved using additive piocesses.In an additive process an object is created by laying down successive (连续的 ) layers of material until the object is created.Each of these layers can be seen as a thinly sliced horizon till (水平的)cross-section of the eventual object.Today's 3D printers are being used to print everything from design models to jewelry,crafts,product parts,body parts,and even food.
3D printing starts with making a virtual design of the object you want to create.This virtual design is for instance a CAD (Computer Aided Design) file.This CAD file is created using a 3D modeling application or with a 3D scanner (to copy an existing object).A 3D scanner can make a 3D digital copy of m object.
You will have to prepare a 3D model before it is ready to be 3D printed.This is what they call slicing.Slicing is dividing a 3D model into hundreds or thousands of horizontal layers and needs to be done with software.
Sometimes a 3D model can be sliced from within a 3D modeling software application.It is also possible that you are forced to use a certain slicing tool for a certain 3D printer,
When the 3D model is sliced,you are ready to feed it to your 3D printer.This can be done via USB.SD or WiFi.It really depends on what brand and type 3D printer you have.
When a file is uploaded in a 3D printer.the object is ready to be 3D printed layer by layer.I'he 3D printer reads every slice(2D image) and creates a three dimensional object.
Before you pick up a 3D printer and experimenting in the 3D world,consider how big the objects you might want to create,If your goal is to print foot-long rulers,you'll fall short of that goal if the printer you choose can only handle objects smaller 6inches in height and width.
Another reality check is print speed.,You'll be able to knock out a days worth of chores(琐事)while the primer is running,with a typical 4-inch model requiring as many as 12 hours to print.As with ordinary printers,print speed also depends on how well it prints.
