break bounds meaning in English

超界

I did not fear her breaking bounds ; because the gates were generally locked , and i thought she would scarcely venture forth alone , if they had stood wide open
我并不怕她越出界外，因为大门总是锁住的，而且我以为就是门大开着的话，她也不敢一个人贸然而去。
In the course of the tale i had mentioned mr . lloyd as having come to see me after the fit : for i never forgot the , to me , frightful episode of the red - room : in detailing which , my excitement was sure , in some degree , to break bounds ; for nothing could soften in my recollection the spasm of agony which clutched my heart when mrs . reed spurned my wild supplication for pardon , and locked me a second time in the dark and haunted chamber
我在叙述自己的经历时，还提到了劳埃德先生，说他在我昏厥后来看过我。我永远忘不了可怕的红房子事件，有详细诉说时，我的情绪有点失态，因为当里德太太断然拒绝我发疯似的求饶，把我第二次关进黑洞洞闹鬼的房子时，那种阵阵揪心的痛苦，在记忆中是什么也抚慰不了的。
