when a thing reaches its extreme, it reverses its course物极必反Extremes meet.物极必反。No extreme will hold long.物极必反。"A thing turns into its opposite if pushed too far";hence constitutional government is now on the order of the day.物极必反，宪政为先。That things turn for the worse when they reach the extreme seems not to be something which people take heed of. 物极必反的道理，似乎很难在人们心中起警惕的效应。Things will turn into their opposites if pushed too far, as the saying goes. Adolescents, who are apt to rebel against authority, hate being ordered about. Apparently, they may observe the bans imposed on them, but that is no victory for their superiors because resentment may be brewing deep in their hearts. The pent-up discontent may grow to form abnormal psychology in them, which will be even more harmful. 俗话说物极必反，处在叛逆阶段的中学生最讨厌别人的摆布，你抑制他们的行为，他们表面上或许服从你，但这种服从不是校方的胜利，因为说不定他们在心底正郁积着不满情绪，而这种情绪久而久之就会发展为更可怕的变相性格。
