例句：Narrator: Listen to part of a lecture in a university course. Professor: Today I want to focus on AI assistance. Many people notice the visible problem, but they often miss the system behind it. The first point is academic integrity, which helps shape what individuals can actually do. A second factor is draft revision; without it, even well-designed plans may fail. Let me give you a simple example. When a campus changes only one rule, students may react for a week. When the rule is connected with feedback, facilities and clear responsibility, the change becomes easier to maintain. This is why researchers now pay attention to critical judgment, not just personal motivation. The practical conclusion is modest: policy should make the desirable action convenient, measurable and socially normal. If you remember one thing from this lecture, remember that this issue is not an isolated detail but part of a larger pattern.
