Apple has entered the textbook market. The tech giant（科技巨头） introduced iBooks textbooks a couple of weeks ago when it announced its iBooks 2 platform. They are digital books in many subjects taking in science, maths, history and geography.
Apple developed its iPad-based textbooks in conjunction with（连接）major textbook publishers. The company offers a collection of textbooks for high school students.
Apple says it offers a “new textbook experience” and suggests its iBooks textbooks are “the next chapter in learning”. It sounds like good news for pupils and students. Think of it. No more carrying heavy backpacks full of textbooks. Every textbook you require can be stored on your iPad. No more having to buy expensive textbooks which you will only use for a year or two and then sell or give away.
Of course there’s a catch. You need to own an iPad and as you know, it is not cheap. You also need to buy digital textbooks, mostly priced each at $14.99 (94.74 yuan) or less. Textbook publishing was worth $ 8.7 billion in the US alone last year. And the rest, as they say, is history. Will Apple revolutionize learning? Will digital books take over completely in education? That remains to be seen.

(答案→)A 解析：本文陈述了苹果发布iBooks 2成为苹果向教育领域迈出的重要一步。那么苹果究竟能否掀起这场学习革命呢？让我们拭目以待。【小题1】【小题2】从第二段No more carrying heavy backpacks. Every textbook you require can be stored on your iPad.可推断出苹果电子书便于携带。【小题3】从下文You need to own an iPad and ...it is not cheap. You also need to buy digital textbooks可知虽然苹果电子书有很多优点，但也存在问题：昂贵。所以a catch【小题4】从最后一段Will digital books take over completely in education? That remains to be seen可排除ABC，在文章第二，三段分别提到苹果电子书的优缺点，所以可知D为正确答案。
