填空题
Teachers should take steps to prevent students from cheating on exams. To begin with, teachers should stop reusing old tests. Even a test that has been used once is soon known on the student grapevine. Students will check with their friends to find out, for example, what was on Dr. Smith’s biology final last term. They may even manage to turn up a copy of the test itself, accidentally not turned in by a former student of Dr. Smith’s. Teachers should also take some commonsense precautions at test time. They should make students separate themselves--by at least one seat--during an exam, and they should watch the class closely. The best place for the teacher to sit is in the rear of the room, so that a student is never sure if the teacher is looking at him or her. Last of all, teachers must make it clear to students that there will be stiff penalties for cheating. Anyone caught cheating should immediately receive a zero for the exam. A person even suspected of cheating should be forced to take an alternative exam in the teacher’s office. Because cheating is unfair to honest students, it should not be tolerated. Obviously, if the above measures are taken, cheating can be effectively prevented at school.
