1、回答1-11题:

Can Digital Textbook Truly Replace the Print Kind?

The shortcomings of traditional print edition textbooks are obvious: Forstarters they're heavy, with the average physics textbook weighing 3.6 pounds.They're also expensive, especially when you factor in the average collegestudent's limited budget, typically costing hundreds of dollars every semester.

But the worst part is that print version of textbooks are constantlyundergoing revisions. Many professors require that their students use only thelatest versions in the classroom, essentially rendering older texts unusable.For students, it means they're basically stuck with a four pound paper-weightthat they can't sell back.

Which is why digital textbooks, if they live up to their promise, couldhelp ease many of these shortcomings. But till now, they've been something likea mirage (幻影) in the distance,more like a hazy (模糊的) dream thanan actual reality. Imagine the promise: Carrying all your textbooks in a 1.3pound iPad? It sounds almost too good to be true.

But there are a few pilot schools already making the transition (过度) over to digital books. Universities like Cornell and Brown havejumped onboard. And one medical program at the University of California,Irvine, gave their entire class iPads with which to download textbooks justlast year.

But not all were eager to jump aboard.

"People were tired of using the iPad textbook besides using it forreading," says Kalpit Shah, who will be going into his second year atlrvine's medical program this fall. "They weren't using it as a source ofcommunication because they couldn't read or write in it. So a third of thepeople in my program were using the iPad in class to take notes, the otherthird were using laptops and the last third were using paper and pencil."

The reason it hasn't caught on yet, he tells me, is that thefunctionality of e-edition textbooks is incredibly limited, and some studentsjust aren't motivated to learn new study behavior.

But a new application called Inkling might change all that. The companyjust released an updated version last week, and it'll be utilized in over 50undergraduate and graduate classrooms this coming school year.

Digital textbooks are not going to catch on," says Inkling CEO MattMaclnnis as he's giving me a demo (演示) over coffee. "What I mean by that is the current perspectiveof the digital textbook is it's an exact copy of the print book. There's CourseSmart, etc., these guys who take any image of the page and put it on a screen.If that's how we're defining digital textbooks, there's no hope of that becominga mainstream product."

He calls Inkling a platform for publishers to build rich multimediacontent from the ground up, with a heavy emphasis on real-world functionality.The traditional textbook merely serves as a skeleton.

At first glance Inkling is an impressive experience. After swiping (敲击) into the iPad app (软件), which youcan get for free here, he opens up a few different types of textbooks.

Up first is a chemistry book. The boot time is pretty fast, and henavigates through (浏览) a fewchapters before swiping into a fully rendered 3D molecule that can be spunaround to view its various building blocks. "Publishers give us all of thesource media, artwork, videos," he says, "We help them think throughhow to actually build something for this platform."

Next he pulls up a music composition textbook, complete with playabledemos. It's a learning experience that attacks you from multiple sensorydirections. It's clear why this would be something a music major would love.

But the most exciting part about Inkling, to me, is its notation (批注) system. Here's how it works!

When you purchase a used print book, it comes with its previous owner'shighlights and notes in the margins. It uses the experience of someone whoalready went through the class to help improve your reading (how much you trusteach notation is obviously up to you).

But with lnkling, you can highlight a piece of content and make notes.Here's where things get interesting, though: If a particularly importantpassage is highlighted by multiple lnkling users, that infbrmation is stored onthe cloud and is available for anyone reading the same textbook to come across.Thai means users have access to notes from not only their classmates andFacebook friends, but anyone who purchased the book across the country. Thebest comments are then sorted democratically by a voting system, meaning thatyour social learning experience is shared with the best and brightest thinkers.

As a bonus, professors can even chime in (插话) on discussions. They'll be able to answer the questions ofstudents who are in their class directly via the interactive book.

Of course, Inkling addresses several of the other shortcomings intraditional print as well. Textbook versions are constanly updated, motivatingpublishers by minimizing production costs (the big ones like McGraw-Hill arealready onboard). Furthermore, students will be able to purchase sections ofthe text instead of buying the whole thing, with individual chapters costing aslittle as $2.99,

There are, however, challenges.

"It takes efforts to build each book," Maclnnis tells me. Andit's clear why,

Each interactive textbook is a media-heavy experience built from theground up, and you can tell that it takes a respectable amount of manpower toput together each one.

For now the app is also iPad-exclusive, and though a few of theseeducational institutions are giving the hardware away for free, for otherstudents who don't have such a luxury it's an added layer of cost ---and anexpensive one at that.

But this much is clear. The traditional textbook model is and has beenbroken for quite some time. Whether digitally interactive ones like Inklingactually take off or not remains to be seen, and we probably won't have adefinite answer for the next few years.

However the solution to any problem begins with a step in a direction.And at least for now, that hazy mirage in the distance? A little more tangible(可触摸的), a little less of a dream.

The biggest problem with traditional print textbooks is that

A.they are not reused once a new edition comes out

B.they cost hundreds of dollars every semester

C.they are too heavy to carry around

D.they take a longer time to revise
