EN： This sentence reflects a high-level academic and policy-making register. In Western public health discourse, the tension between 'complacency' (feeling too safe) and 'vigilance' (staying alert) is a recurring theme used to justify ongoing funding and strict regulations even when a crisis seems to have passed.
中文： 這句話反映了高階學術與政策制定的語域。在西方的公共衛生論述中，「自滿」（complacency，指過度安全感）與「警覺」（vigilance，指保持警惕）之間的拉鋸是一個經常出現的主題，用來證明即使在危機似乎已經過去時，持續的資金投入和嚴格監管仍具正當性。
EN： The Subjunctive Mood after adjectives of urgency or importance: When using adjectives like 'imperative', 'essential', or 'crucial' in the structure 'It is [adjective] that...', the following clause uses the base form of the verb (subjunctive), regardless of the subject. In this sentence, 'be strengthened' is used instead of 'is strengthened'.
中文： 在表示緊迫或重要性的形容詞（如 imperative, essential, crucial）之後的虛擬語氣：在 'It is [形容詞] that...' 的結構中，從句動詞必須使用原形（虛擬語氣），不論主詞為何。在本句中，使用的是 'be strengthened' 而非 'is strengthened'。
It is essential that every member be informed of the new policy immediately.
每位成員都必須立即獲知這項新政策，這是至關重要的。
EN： Parallel Structure in lists: When listing multiple items as objects of a preposition (in this case, 'in'), all items should maintain the same grammatical form. Here, 'surveillance', 'vaccine research', and 'resource allocation' are all noun phrases acting as objects.
中文： 列表中的平行結構：當多個項目作為介系詞（此處為 'in'）的受詞時，所有項目應保持相同的語法形式。這裡的 'surveillance'、'vaccine research' 和 'resource allocation' 均為名詞短語。
The project focuses on data collection, analysis, and reporting.
該項目專注於數據收集、分析和報告。
EN： The sentence reflects the formal register of international diplomacy and global health policy. Terms like 'surveillance' in a public health context refer to the systematic collection and analysis of health data to monitor disease outbreaks, rather than police-style monitoring.
中文： 這句話反映了國際外交和全球衛生政策的正式語體。在公共衛生語境下，「surveillance」（監測）是指系統性地收集和分析健康數據以監控疾病爆發，而非指警察式的監視。
EN： Negative/Restrictive Inversion: When a sentence begins with a restrictive phrase starting with 'Only' (e.g., 'Only through...', 'Only when...'), the subject and the auxiliary verb are inverted. This is used for formal emphasis.
中文： 否定/限制性倒裝句：當句子以帶有 'Only' 的限制性短語（如 'Only through...', 'Only when...'）開頭時，主詞與助動詞需進行倒裝。這常用於正式語氣以示強調。
Only by working together can we overcome this global challenge.
唯有透過通力合作，我們才能克服這項全球挑戰。
EN： The use of 'sustained' as an attributive adjective: Derived from the verb 'sustain', it describes something that is maintained for a long period without weakening, often used in professional or academic contexts regarding effort or growth.

The economy has seen sustained growth over the past decade.
過去十年來，經濟見證了持續性的增長。
EN： Infinitive as Object Complement: The verb 'hope' is followed by a 'to-infinitive' to express a desire for a future outcome that is possible but not certain.
中文： 不定詞作為受詞補語：動詞「hope」後接「to-不定詞」，用以表達對未來某種可能但非必然結果的期望。
Scientists hope to develop a universal vaccine within the next few years.
科學家希望在未來幾年內研發出全能疫苗。
EN： The sentence reflects a shift in global discourse post-COVID-19, emphasizing 'infrastructure' and 'preparedness' over reactive measures. The word 'inevitable' suggests a scientific consensus that future pandemics are a matter of 'when', not 'if'.
中文： 這句話反映了後疫情時代全球論述的轉變，強調「基礎設施」與「預備工作」重於事後反應。使用「inevitable」（不可避免的）一詞，暗示了科學界的共識：未來的流行病爆發只是「何時」發生，而非「是否」會發生的問題。
