[名词] 门槛
深入解读
对于港剧迷来说，看到 threshold 这个单词，很容易联想起经典 TVB 港剧《创世纪》（At the Threshold of an Era）来，其片头的英文译名中就出现了这个单词。
该词本义比较简单，就是日常生活中随处可见的“门槛”，也可以指“门口”，比如站在门口犹豫不决（stand hesitating on the threshold）、迈过门槛（step across the threshold）。
从越过门槛才能进门这个概念出发， threshold 很自然地就被用来引申指“阈、界、起始点”，主要指发生或表现出某种反应、现象、结果或状况而必须超过的程度或强度，比如：
- 我没办法凭空变出几百万美元。我的收入才刚刚超过征税起点。
I could not conjure up millions of dollars out of thin air. My earnings are just above the tax threshold. - 那个贪吃的人容易感到厌倦，需要时常进行体力活动来刺激一下。
That voracious eater has a low threshold of boredom and needs the constant stimulation of physical activity.
而习语 on the threshold of sth 则相应表示“在……的开始、在……的起点”，常意味着即将进入一个新且重要的时期或发展阶段，比如：
- 这个因监狱状况恶劣而臭名远扬的国家即将爆发内战。
The country notorious for its appalling prison conditions is on the threshold of civil war.
演讲用例

但是对于等候在正义之宫门口的心急如焚的人们，有些话我是必须说的。在争取合法地位的过程中，我们不要采取错误的做法。
