I think one reason is that the way teachers teach is a bit old-fashioned. Most of the time, it's just listening to the teacher talk or memorizing things from the book. There's not much chance to do activities or group work, so students get bored easily. If teachers made lessons more interesting or connected them to real life, maybe students would enjoy learning more.
我认为一个原因是教师的教学方式有点过时。大多数时候,就是听老师讲课或死记书本上的内容。几乎没有机会进行活动或小组合作,所以学生很容易感到无聊。如果老师能让课堂更有趣或者把内容和现实生活联系起来,也许学生会更喜欢学习。
