ask high school teachers if rebellious students learn anything of value.ask teachers if these students do any homework.ask if the threat of low grades motivates them.quite teh contrary,these students know they will be passed from grade to grade until they are old enough to quit or until,as is more likely,they receive a high school diploma.at the point when students could legally quit,most choose to remain since they are likely to be allowed to graduate whether they do acceptable work or not.

问问高中老师反叛的学生是否学会什么,问问老师这些学生做功课吗.问问,威胁给他们低分能激励他们吗.相反,这些学生知道他们会一级一级的升上去,直到他们长大到可以退学,或着,更有可能的是,直到他们获得高中毕业证书.
当学生可以合法地退学时,多数人会选择留在学校,因为无论他们是否做功课,
他们都会被允许毕业.
