教烂班 英语怎么说

"教烂班" 英文翻译是 "teach a class to death."
来源：这个短语源自中文，表示一种过度教学的状态，即教师把知识和技能教给学生直到学生不能再接受。这样就会使学生对知识和技能变得厌烦和不想继续学习。
例句:
"He's been teaching that class for so long that he's teaching the class to death." (他教那个课已经很久了，以至于他教烂了这个班级)
"I can't stand this class anymore. The teacher always goes over the same material and it's like she's teaching us to death." (我再也受不了这个班了，老师总是重复同一个材料，就像她在教烂我们一样)
