While carrying your schoolbag on the way to school or home，does the heavy weight of your books make you less interested to learn knowledge？Don't worry.E-readers may help you say goodbye to your heavy schoolbag.
An e-reader has the memory space to hold hundreds of books.So people want to replace heavy schoolbags with small，light e-readers.For example，Cushing Academy，a high school in Massachusetts，US，got rid of most of the 20，000 books in its library last summer.The head of the library said that the school was going to replace printed books with e-books.Teachers and students will use e-readers instead.
Most e-readers are thin and weigh less than 500 g.They can download an e-book in 60 seconds. "It's so convenient.You can have so many books right at your fingertips!" said Meghan Chenausky，16.
Chinese schoolchildren are also trying e-readers.At the 2010 Shanghai Expo，an e-schoolbag was on show.It is a special e-reader that students can use to download textbooks from the school servers.It can also send and receive homework.
Some schools in Beijing and Shanghai have tried this e-schoolbag for a few years. "It' s excellent.I don't have to carry a heavy schoolbag anymore，" said Xiao Qi，15，Beijing. "And it's eco-friendly because it saves paper."
New generation e-readers have many functions（功能） besides reading，such as Wi-Fi and multimedia.However，some parents worry that these functions may have a bad influence on their children's study habits. "I think Wi-Fi is not necessary for kids，" says Zeng Wenwen，43，Beijing.
