Imagine a classroom missing the one thing that's 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 moment.A“paperless classroom”is what more and more schools are trying to achieve.
Students don't do any handwriting in this class.Instead,they use palm 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 from maths to social science.
High school teacher Judy Herrell in Florida,US,described how her class used the Web to learn about the war in Afganistan(阿富汗) 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.”
And exams can go online too.At a high school in Tennessee,US,students take tests on their own computers.The teacher records the grades on the network for everyone to see and then copies them to his own electronic grade book.
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 about 900 pieces of paper each week to each student.
“Think about the money and trees we could save with the computers,”she said.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(可用的) for these hi?tech students.

Farmer Ed Rawlings smiles as he looks at his orange trees. The young oranges are growing well in Florida's weather. Warm sunshine and gentle rains, along with Ed Rawlings' expert care, will produce a good crop of oranges this year.
But Ed has to fight against Florida's changeable winter weather. In January and February, temperatures can destroy Ed's entire orange, crop. Having farmed in Florida for the past 35 years, Ed Rawlings is prepared for the frosts(霜). When temperatures drop below freezing, Ed tries to save his crop by watering his orange trees. The water freezes and forms a thin layer (层)of ice on the trees. Strange as it may sound, this thin layer of ice actually keeps the fruit warm.
What happens is simple. When the trees are watered, the water loses heat and becomes ice. The warmth of the heat it loses is sucked in by the fruit and keeps its temperature at a safe level. Ed Rawlings has effectively used this method(方法)to save many orange crops.
But Ed still faces some difficulties. The trees should be watered at the exact moment the temperature drops to the freezing point. Also, just the right quantity of water must be used. Too much water can form a thick layer of ice that will break the trees' branches. Another difficulty is that wind blows away the heat. So Ed has to worry about not only when but also how often his trees should be watered, and how much water should be used.
Computer technology may help Ed Rawlings with some of these worries. With equipment, air and soil temperatures and wind speed can be measured. The information is fed into a computer which can tell when temperatures drop to freezing. The computer can correctly decide the quantity of water to be used and how frequently the trees should be watered. Ed Rawlings will find looking after his orange trees a lot easier with the help of a computer, and we'll all have the benefits(or advantages)of computer-age oranges.
