Our school is replacing printed textbooks with e-textbooks next semester. I can't wait.
Really? What about the cost, not only buying all those tablets,
but the software and electronic infrastructure that goes with it, not to mention retraining all the teachers and administration staff?
Sure, the initial expenditure will be high, but much lower afterwards.
当然 。最初的支出会很高，但之后会低很多 。
Besides that, tablet prices continue to drop and are becoming increasingly affordable.
Anyway, tablets help students learn up to 80% faster.
Not necessarily. Tablets have too many distractions. Students may pay attention to apps, games and websites instead of their teachers.
不一定，平板电脑有太多让人分心的地方 。学生可能会将注意力放在各种应用程序、游戏和网站上，而不是他们的老师身上 。
In fact, research suggests that people who read printed text comprehend more, remember more and learn 30% more than those who read digital text.
Yes. But tablets contain many technological features that are not found in printed textbooks.
Think about it. Students are able to highlight and edit text, write notes and search for information much more quickly than they can with printed textbooks.
好好想想 。与印刷课本相比，学生能够更快地突出显示和编辑文本、写笔记和搜索信息 。
And what about all those trees that are cut down to make printed books?
Actually, manufacturing tablets is environmentally destructive and dangerous to human health.
The health impacts from making one electronic reader are 70 times greater than those from making a single printed book.
A lot of minerals are extracted from the earth to make electronic readers. It does far more damage to the environment.
为了制造电子阅读器，从地球上提取了大量的矿物质 。它对环境的破坏要大得多 。
Yes. But the software for electronic readers can be updated instantly without the need for buying a whole lot of new books. That's better for the environment.
是的，但电子阅读器的软件可以即时更新，不需要购买一大堆新书 。这对环境更好 。
But the core curriculum doesn't change that much.
Printed textbooks that are not brand new, still contain the basic relevant information of core subjects.
Well, I'm looking forward to the change.
I'll stick with my printed books.
