     IMAGINE A classroom missing one thing that has long been considered a necessary part to reading and

writing? Paper. No notebooks, no textbooks, no test paper. Nor are there any pencils or pens, which always

seem to run out of ink at the critical (关键的) moment.

     Students don't any handwriting in this class. Instead, they use palm(手掌) size, or specially designed

computers. The teacher downloads texts from Internet libraries and sends them to every student's personal

computer.

     Having computers also means that students can use the Web. They can look up information on any subject

they're studying!

     High school teacher Judy Harrell in Florida, US, described how her class used the Web to learn about the

war in Afghanistan over one year ago.

     "We could touch every side of the country through different sites, from the forest to refugee camps (难

民营)," she said. "Using a book that's three or four years old is impossible."

     A paperless classroom is a big step towards reducing the waste of paper. High school teacher Stephanie

Sorrell in Kentucky, US, said she used to give 900 pieces of paper each week to each student.

     But, with all this technology, there's always the risk that the machines will break down. So, in case of a

power failure or technical problems, paper textbooks are still widely available for these hi-tech students.
