what is the use of advice only if it is not supported by a reasonable degree of control and punishment?这句话什么意思?还有only if的意思?
我觉得这个only if 就等于if。但如果后面不是否定,那么就很好解释了,因为only if 可以解释为“除非”,但若直接这么解释,那就不通了。
我认为应这样断句:what is the use of advice only / if it is not supported by a reasonable degree of control and punishment? 如果没有适当程度的监控和惩罚措施,光有建议有什么用?
