Borrowed material was most likely to appear at the end of a statement or where the applicant described the reasons for wanting to study a subject. Almost all applications are now completed online, but the new evidence of Internet temptation(诱惑)follow concern that teenagers are cutting and pasting material for A-level coursework(课程作业). A spokesman said later that he and his partners were looking for ways examine whether people appeared to be copying material.
