【简答题】
According to the Learner’s Dictionary of Current English, the word “cheating (作弊) ” is “an act to win an advantage or profit in a dishonest way.” More specifically, to cheat on an examination is to obtain information in an illegal way, such as by copying solutions from the test paper of a neighbor or bringing into the exam a cheat sheet with the required information written on it.
