    Cheating on exams is popular in colleges and statistics show that it has risen dramatically during the past score years. Students don’t feel ashamed to cheat on exams. Most of them don’t care about cheating on exams.
    Cheating on exams takes shape in various ways. Some students scribbled notes on small pieces of paper on which they had prepared for the exam, some took out their textbooks or reference books to copy, and still some adopted mobile phones as a way to cheat on exams. For instance, at the University of Nevada, students photographed test questions with their cell phone cameras, then sent them to classmates outside the exam room and got the answers back in text message. However, downloading other people’s writing on the Internet for plagiarism(剽窃) was found the easiest way.
    Mr. Dapremont said technology had made cheating easier, but added that pressure to succeed sometimes clouded everything and made students do things that they shouldn’t do. Students today feel more pressure to do well in order to graduate from school and land jobs.
    Whatever the reasons for cheating are, college officials say we must stop it. First, people will not be interested in studying any more with cheating. Second, they think studying isn’t meaningful. Third, others may be influenced negatively by people cheating on exams. Thus, we must ban cheating on exams. We should reduce opportunity of cheating on exams.
    Most Americans still believe that honesty is an important part of American character. For that reason, there are numerous watchdog committees at all levels of society. Although signs of dishonesty in school, business, and government seem much more numerous in recent years than in the past, could it be that we are getting better at uncovering such dishonesty?
    Many educators feel that as students gain confidence in themselves and their abilities, they are less likely to cheat.
