     It has been more than twenty years since pioneering British computer programmer, Sir Tim Berners

Lee, created the World Wide Web. But could he have ever imagined how much the web would change

our lives? And would he approve of how some British students are taking advantage of his invention?

     Universities and exam boards around the UK are becoming increasingly concerned with the rising

number of cases of plagiarism, many of which are facilitated (助长) by the Internet access.

     In the UK most school and university students complete coursework throughout the academic year

which contributes toward their final mark. In many cases coursework makes up the main part of the

qualification. Since coursework is completed in the students' own time it cannot be monitored by teachers

in the same way as an exam.

     Derec Stockley, director of examinations in the UK, explains, "Plagiarism affects coursework more

than anything else, and in the cases that come to our attention, more and more are linked to the Internet."

     At a university level recent reports suggest that plagiarism has evolved from separate cases of

individual cheating to systematic and even commercial operation. Students can now pay for bespoke

essays to be written for them by experts.

      It is estimated that the market in online plagiarism is now worth 200 million pounds a year. Every

month more and more websites offering to write student's essays for them appear on the Internet.

Barclay Littlewood, owner of Degree Essays UK employs 3,500 specialist writers and charges between

120 pounds and 4,000 pounds per essay. However, Mr. Littlewood refutes the accusation that he is

helping students to cheat.
