Children at a school in Italy have today begun an experiment to replace all their books with personal computers. The pupils involved will each be given a special laptop that contains their entire courses. Until today, the Don Milani di Rivoli elementary school in central Turin was like any other. Children turned up, got out their books and pens and began the process of learning. But now, in what's being described as a unique experiment, 60 fifth-grade pupils and a number of third-graders, will start using computers only. The mini-laptops, which run Windows software, all have a full curriculum programmed into them. The pupils will use the computers to do all their reading and writing. Security systems within the laptops mean the children's access to the Internet is strictly controlled. The machines weigh less than a kilogram, can be dropped from a height of 1.5 metres and are waterproof. Instead of spending 700 dollars a year on books, the laptops, built by the Italian company Olidata, cost less than 400 dollars. One of the teachers involved in the scheme says that, for the first time, schools will be able to verify in a scientific way how a computer alone can improve the learning process. The experiment, which has the backing of parents, is due to last a year. In other countries, such a programme is also being carried out. Venezuela is ordering one million low cost laptops for its school children. The machines will be based on the Intel Classmate laptop that has been designed for school children. Many see the deal as a blow for the One Laptop Per Child organization that has also been introducing its child- friendly machine to developing nations. 小题1: Which of the following is TRUE about the mini-laptop?
