句式分析 ：
“the threat of cholera around the world saw a substantial decrease”是一个以无生命的名词词组作主语的句式。“无生命的名词＋see/find/witness…”意为“……经历、发生、见证、目睹某事”。有些动词，如see, find, witness等，可以用地点或时间名词作主语，表示某地或某时经历、发生、见证或目睹某事。
Beijing has witnessed great changes in recent years.
北京见证了最近几年的的巨大变化。

excitement兴奋；surprise 惊讶；shame 羞耻羞愧；anger 愤怒；despair 绝望；regret 遗憾后悔；sorrow 悲伤；horror 惊恐；anxiety 焦虑；disappointment 失望沮丧；satisfaction 满意满足等。
常见的谓语动词：seize 侵袭；flood over充满; wash over 洗涤侵袭； well up涌出;take hold of抓住
