Personally, I don't think it's always possible or even necessary to make every lesson fun. Certain subjects, like advanced maths or physics, are inherently complex and require a more serious approach. If teachers focus too much on entertainment, students might lose sight of the main topic and not take the material seriously. Besides, not every teacher feels comfortable or confident using fun teaching methods, so it could end up being more distracting than helpful in some cases.
就我个人而言,我认为并不总是有必要或可能让每节课都变得有趣。某些学科,比如高级数学或物理,本质上就很复杂,需要采用更严肃的教学方法。如果老师过于注重娱乐,学生可能会忽视主要内容,不能认真对待学习材料。此外,并不是每位老师都觉得使用有趣的教学方法感到舒适或自信,因此在某些情况下,这反而可能分散注意力,弊大于利。
