Do you know Course Smart？It is an American company（公司）that makes digital textbooks（数字课本）．It has made a plan to provide 7，000digital textbooks for students．The plan has special meanings to American students．
Let me tell you the price of digital textbooks．Students in the United States and Canada can buy the digital textbooks at about half the price of the printed versions（印刷版）．Course Smart's textbooks are a little cheaper，but you can only use them for 180days．
The digital textbooks will allow students to get digital notes and search for words or phrases．They can also use their iPhone or iPad Touch to read their e-textbooks quickly．They can even look through their notes in the classroom．
"Nobody is going to use their iPhone to do their homework，but this does provide real mobile learning，"Frank Lyman from Course Smart said，"If you're in a study group and you have a question，you can look it up in your textbook at once．"
