Exercise: Analyze the thematic progressive pattern of the following text and try to illustrate how such a pattern contributes to the coherence of the text.
Teachers should take steps to prevent students from cheating on exams. (2) To begin with, teachers should stop reusing old tests. (3) Even a test that has been used once is soon known on the student grapevine（小道消息）. (4) Students will check with their friends to find out, for example, what was on Dr. Thompson’s biology final last term. (5) They may even manage to turn up a copy of the test itself, “accidentally” not turned in by a former student of Dr. Thompson’s. (6) Teachers should also take some common sense precautions（防范措施）at test time. (7) They should make students separate themselves -- by at least one seat -- during an exam, and they should watch the class closely. (8) 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. (9) Last of all, teachers must make it clear to students that there will be severe penalties for cheating. (10) Anyone caught cheating should immediately receive a zero for the exam.
