　　Apple has entered the textbook market．The tech giant introduced(推出)iBooks textbooks many weeks ago．They are digital books in many subjects taking in science, maths, history and geography．Apple says it offers a “new textbook experience” and suggests its interactive(互动的)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 need 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which you will only use for a year or two and then sell or give away．Instead of boring old textbooks which are quickly out of date you can have an interactive learning experience．You can play videos, examine geometrical(几何)problems in 3D, listen to music，make notes and mark passages electronically．You can also share stuff(材料)on social networking sites with your friends．

　　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 more．And the rest, will Apple revolutionize(改变)learning? As they say, is history．That remains to be seen．
