An ebook is an electronic book presented in a digital format. It is a little bigger than a schoolbook. It has several buttons and a display screen for reading. There is an Internet connection port for downloading. You can make a note, browse, or even look up a word in the dictionary while reading.

　　It’s very convenient. Even so, it is believed that it will still not replace the traditional book in the near future. But some big electronic companies such as Microsoft and Amazon have pointed out that it is very cheap to access new reading material using an e-book, so why wouldn’t you have one?
