What is an e–reader? An e–reader is a small computer. It can hold thousands  of e–books. So people want to throw away heavy schoolbags and read with small, light e–readers. For example, a US high school has put its paper books away. Teachers and students are using e–readers now. “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. Hanvon WISEreader is the most popular e–reader in China. It weighs about 260g and is as big as a regular textbook. It is a special e–reader. Students can make notes on it. They can use it to download textbooks from school computers. It can also send and receive homework. New e–readers are not just for reading. They have WI-FI(无线网络) and multimedia(多媒体).Parents think these may hurt children’s study habits. “I think WI-FI is not necessary for kids.” says Zeng Wenwen,43, Beijing.
