Apple has entered the textbook market.The company(51)introduced(介紹) iBooks textbooks four years ago.iBooks textbooks are digital books in different subjects,(52)including(包括) science,math,history and (53)geography(地理).The company(54)provides (提供) a collection of textbooks for high school students.It offers a"new textbook experience"and suggests that the interactive iBooks textbook(55)themselves(本身) are"the next chapter in learning."It sounds like good news for students.Think of it.No more carrying heavy backpacks (56)filled(滿) with textbooks.Every textbook you need can be(57)stored(儲存) 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 hidden problem.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 (94.74yuan) or (58)less(更少).Textbook publishing was(59)worth(值) 8.7billion in the US alone last year.And the rest,as they say,is history.
Will Apple revolutionize learning?Will digital books take over (60)completely (完全) in education?That remains to be seen.
