中文： 1972-73 年的聖嬰現象在歷史上具有重要意義，因為這是科學家和經濟學家首次完全意識到氣候異常與人類糧食系統之間全球性關聯的事件之一。當時秘魯鯷魚漁場是全球最大的單一物種漁場，也是全球動物飼料的主要來源，其崩潰引發了全球大豆和穀物價格的暴漲，展示了局部生態破壞如何級聯演變成全球性的經濟危機。

It is set off by commas because it is non-restrictive (the subject is already a specific proper noun).

EN： The 'Ethiopian Public Health Institute' (EPHI) is a prominent government body in Ethiopia dedicated to improving the health of the general public through research and rapid response to health emergencies.

中文： 「衣索比亞公共衛生研究所」（EPHI）是衣索比亞著名的政府機構，致力於透過研究和對突發衛生事件的快速反應來改善公眾健康。在東非，像聖嬰現象這樣的氣候異常與公共衛生危機有著深深的聯繫，因為乾旱和洪水會直接引發營養不良以及瘧疾等媒介傳播疾病，這使得該地區的流行病學研究顯得至關重要。

EN： The sentence refers to the devastating 1972-1973 drought in Ethiopia, which was severely exacerbated by the El Niño phenomenon. This environmental disaster led to widespread famine, particularly in the Wollo province. The inability of Emperor Haile Selassie's government to effectively respond to the famine led to massive public outrage and protests, which ultimately contributed to the 1974 military coup that deposed the monarchy and established the Derg, a communist military junta. The transformation of a school classroom into a grain store ('grain store' in British English, equivalent to 'granary') vividly illustrates how local communities had to sacrifice education for basic survival.
中文： 此句子指的是 1972 至 1973 年間在衣索比亞發生的毀滅性乾旱，該乾旱因聖嬰現象而嚴重加劇。這場環境災難導致了廣泛的饑荒，特別是在沃洛省（Wollo）。皇帝海爾·塞拉西（Haile Selassie）政府因未能有效應對饑荒而引發了巨大的民憤和抗議，最終促成了 1974 年的軍事政變，推翻了君主制並建立了共產主義軍事執政團「德爾格」（Derg）。將學校教室改造成穀倉（英式英語中的 'grain store'，相當於 'granary'）生動地描繪了當時地方社區不得不犧牲教育以求基本生存的悲慘現實。

中文： 「A, rather than B,」（是A而非B）结构用于对比两个要素，强调A才是首选或正确的选项，而非B。当此结构置于主语与动词之间时，它起着插入语的作用，且不改变主语的单复数（动词须与主要主语「proactive intervention」一致，在此为单数）。
