Помогите перевести текст.
Churchill Community School in Somerset is a place where pupils and staff have mastered the art of getting what they want out of their computers. Like many schoolboys, Philip Eagle and his friends enjoy making paper aeroplanes. The only difference is that these boys are being given lips by a computer. "It's physics, aeronautics and education," insists Philip. He forgets to add that it's also a pleasant way of passing the time during the morning break. He is currently working on his personal statement for the UCAS university entrance form. "I've word-processed it so I can get more words into the space on the form. Apart from that, it looks much better type-written."
He is one of the many pupils at Churchill Community School who have chosen to spend their twenty minutes of freedom in the learning resource centre. Here they can borrow books, do last-minute homework, catch up on gossip or take a turn on one of the computers that are always available for them to use.
Students use the computers for a wide variety of tasks. Ian Blomfield, for example, used a CD-ROM of back-issues of The Times and Sunday Times, along with the electronic encyclopedia Encarta, to find out about environ-. mental damage caused by oil-tanker disasters. But he was able to go a step further. He used E-mail to pick the brains of campaigners and Friends of the Earth. "There was no other way we could have got such up-to-date information," he says.
Because of a technologically advanced link to the Internet, twenty-eight computers can remain permanently on line. Cliff Harris, the school's computer technician, explains that pupils can use the Internet as easily as any piece of software. "A lot of students are likely to have a PC at home in their room," he adds. "They go home and have conversations with their schoolmates on the Internet."
Most children seem to use their PC in a way that would please any teacher. Charles Palmer, who can also be found in the resource centre at break-time, says, "I didn't exactly learn to read using a computer, but it was the adventure game Monkey Island that made me really want to learn. If I couldn't read what was on the screen, I couldn't play the game." Charles also uses his PC for designing his family's Christmas cards.
Helen Brown finds that her PC is an invaluable home tutor that can offer her that little extra bit of help. "Sometimes there are things in algebra or biology that teachers only go over once, and I don't understand them. But I can use a program I've got at home which explains it again and again until I do understand it!" However, she isn't impressed by the possibility of computers replacing teachers. "You can't ask a computer questions," she says. "It just asks you."
Her view seems widely shared. "It would be totally boring," says Chris Richmond. "You'd switch the machine off, or switch oft yourself." Nevertheless, he is currently using his PC to write an article on passive smoking, and claims that he is being given the chance to write the best essay he could possibly write with the use of his computer.
Pupils without access to a computer at home are obviously at some disadvantage. The school tries hard to make up for this, however. They want all pupils to have a chance to take advantage of this valuable, interesting -and often fun - form of technology.
