EN： The correlative structure 'shift from [X] to [Y]' requires parallel forms. Here, both X and Y are gerund phrases ('debating the end of fossil fuels' and 'actually delivering it'). The preposition 'to' is followed by a gerund, not an infinitive verb.
中文： 关联短语「shift from [X] to [Y]」（从……转向……）要求前后结构对称。在此句中，X 与 Y 均为动名词短语（'debating...' 与 'actually delivering...'）。特别注意这里的 'to' 是介词，后面必须接动名词（V-ing），而非不定词原形动词。
The company needs to shift from making empty promises to actively reducing emissions.
该公司需要从空口承诺转向切实减少排放。
EN： Apposition: 'co-hosts of Cop31' functions as a non-restrictive appositive noun phrase set off by commas, providing supplementary descriptive information about the compound subject 'Turkey and Australia'.

科学家警告，全球碳排放必须在 2025 年前达到峰值。
EN： In UN climate diplomacy, 'Cop' refers to the Conference of the Parties under the UNFCCC. The phrase 'the end of fossil fuels' remains one of the most contentious geopolitical topics at these summits, as fossil fuel-exporting host countries often face intense international pressure to transition from rhetoric to concrete policy implementation.
中文： 在联合国气候外交中，「Cop」代表《联合国气候变化框架公约》缔约方会议。终结化石燃料（the end of fossil fuels）是此类峰会上最具地缘政治争议的议题之一，身为主办国的化石燃料出口国往往面临巨大的国际外交压力，被敦促将口头承诺落实为实质政策。
EN： Present participle clauses (participial phrases) can appear at the beginning or end of a sentence. At the start ('Speaking on Tuesday'), it sets the temporal and situational context. At the end ('urging delegates to...'), it expresses an accompanying action or result performed by the same subject ('António Guterres').
中文： 现在分词从句（分词短语）可用于句首或句尾。置于句首（如 'Speaking on Tuesday'）用以交代时间或情境背景；置于句尾（如 'urging delegates to...'）则表示主语（安东尼奥·古特雷斯）同时进行的伴随动作或延伸结果。
Addressing the assembly, the director unveiled the new policy, urging all departments to comply immediately.
在向大会发表讲话时，署长公布了新政策，并敦促所有部门立即遵守。
EN： The structure 'treat [something] as [noun/adjective]' expresses how an object is regarded or handled. Combined with modal passive ('should no longer be treated as...'), it formally asserts that a certain perspective or stance toward an issue must cease.
中文： 结构「treat [某物] as [名词/形容词]」表示「将某事物视为／当作……」。结合情态被动语态（'should no longer be treated as...'），可用于正式语境中强烈主张应停止对某议题抱持特定视角或态度。
Mental health concerns should no longer be treated as a sign of personal weakness.
心理健康问题不应再被视为个人软弱的表现。
EN： Parallel infinitive verbs governed by a single auxiliary or marker ('to organise, [to] finance and [to] deliver') are often coordinated in a tricolon (a set of three) for rhetorical impact, with subsequent 'to' markers omitted for brevity.
中文： 由单个不定式符号或助动词引导的平行不定式结构（'to organise, finance and deliver'），常采用「三连句式（tricolon）」以加强修辞节奏与说服力；第二与第三个动词前的 'to' 通常省略以保持简洁。

该委员会旨在两年内规划、资助并执行该项基础设施建设专案。
EN： At international climate negotiations (such as COP summits), discussing an outright 'phase-out' of fossil fuels has historically been politically sensitive—virtually a 'taboo'—due to intense opposition from major oil-producing nations. António Guterres's use of the word 'taboo' directly confronts this diplomatic sensitivity, urging delegates to move past evasive rhetoric into concrete financial and operational commitments.
中文： 在历届联合国气候大会（COP）等国际气候谈判中，由于产油国与能源大国的强烈反对，全面“淘汰化石燃料”的议题历来极为敏感，甚至一度被视作谈判桌上的政治“禁忌（taboo）”。安东尼奥·古特雷斯在此直接点破该词，旨在打破外交上的委婉回避，催促各国代表落实具体的资金投入与执行计划。
EN： When a negative or restrictive expression like 'Not only' begins a clause, negative inversion is triggered: the auxiliary verb ('are') precedes the subject ('both host nations'). The correlative conjunction 'but (also)' links the two clauses.
中文： 当否定或限制性副词短语“Not only”（不仅……）置于句首时，会触发否定倒装句型（Negative Inversion）：助动词或连系动词（are）必须倒装移至主语（both host nations）之前。后面则常搭配对等连接词“but (also)”引导第二个子句。
Not only did the company miss its quarterly target, but it also laid off hundreds of employees.
该公司不仅未达到季度目标，甚至还裁撤了数百名员工。
EN： The past continuous tense ('was extolling') is employed here to vividly depict an ongoing activity in progress around a specific point in past time ('a day before his scheduled summit appearance'), highlighting a sense of irony or contradiction with the climate summit's goals.
中文： 此处使用过去进行式（was extolling），生动描述在过去特定时间点（预定出席峰会的前一天）正在持续进行的动作，并强烈突显出与气候峰会减碳目标之间的讽刺与矛盾感。
The spokesperson was defending the policy just hours before the prime minister announced its complete repeal.
就在首相宣布彻底废除该政策的几小时前，发言人还在为其辩护。
EN： The sentence highlights the political friction inherent in UN climate summits (such as COP). Host nations are expected to lead global decarbonization efforts, yet both Turkey and Australia have substantial fossil fuel interests (Australia in coal/LNG, Turkey in oil and gas transit/extraction). Praise of oilfields right before a climate summit is widely viewed by environmental diplomats as a direct contradiction of climate commitments.
中文： 该句子点出了联合国气候峰会（COP）常见的政治矛盾。主办国通常被期待在引领全球脱碳转型上展现示范作用，然而土耳其与澳洲两国本身皆具庞大的化石燃料利益（如澳洲的煤炭与液化天然气、土耳其的油气开采与输送通道）。在气候峰会前夕公开赞扬油田，常被气候外交界视为对减碳承诺的尴尬矛盾与讽刺。
EN： The Mandative Subjunctive: When verbs expressing demand, recommendation, or insistence (e.g., 'demand', 'insist', 'recommend', 'propose') are followed by a 'that' clause, the verb in the subordinate clause remains in its base form (bare infinitive), regardless of the subject's person or number, and without tense shifting into the past (e.g., 'demanded that the talks conclude', not 'concluded').
中文： 命令/要求语气之虚拟语气（Mandative Subjunctive）：当主句使用表示要求、建议、坚持的动词（如 demand、insist、recommend 等）接 that 子句时，从属子句的动词必须使用原形动词（bare infinitive），不因主词人称、单复数或主句过去时态而变化（此处为 conclude 而非 concluded）。

委员会要求每位代表必须在中午前提交报告。

中文： 名词同位语片语：在「Brazil, last year's host, unveiled...」中，名词片语「last year's host」以逗号隔开作为补充说明的同位语，简洁地提供「巴西」的背景资讯，避免使用冗长的关系子句（如 who was last year's host）。
The proposal by Canada, the summit's co-chair, received broad support.
作为峰会共同主持国的加拿大所提出的提案获得了广泛支持。
EN： Nested Modifiers and Prepositional Phrasing: Advanced formal English often piles prepositional phrases and relative clauses to build precise meaning: [clear next steps] + [on the fossil fuel transition roadmap] + [that Brazil... unveiled to delegates]. Each layer narrows down the scope of the objective.
中文： 多层次修饰与介系词片语堆叠：高阶正式英语常借由介系词片语与关系子句层层修饰，界定精确概念：核心名词 [clear next steps] 接介系词片语 [on the fossil fuel transition roadmap]，再由关系代名词子句 [that Brazil... unveiled to delegates] 修饰路线图。
We need definitive action on the biodiversity preservation framework that member states approved last month.
我们需要针对成员国上个月批准的生物多样性保护框架采取明确行动。
EN： In UN climate diplomacy (such as COP summits), language choice carries immense political weight. The phrase 'roadmap' signifies an agreed timeline with binding commitments rather than vague intentions. Brazil, having hosted COP30 in Belém, positioned itself as a champion of actionable fossil fuel phase-out frameworks, putting moral and diplomatic pressure on subsequent hosts to continue momentum rather than backtrack.
中文： 在联合国气候外交（例如缔约方会议 COP）中，措辞具有高度政治敏感性。「路线图」（roadmap）意味着具约束力与明确时间表的行动方案，而非抽象口号。巴西（Brazil）身为主办国时提出了化石燃料逐步淘汰框架，古特雷斯此处发言意在施压后续主办国维持政策动能，不得开倒车。
EN： The sentence begins with a past-participial phrase ('Backed by...'), functioning as an adverbial modifier indicating background circumstances, cause, or support. In formal written English, fronting a participial phrase creates a cohesive transition and naturally connects secondary details to the main clause subject ('the outgoing secretary general').
中文： 句子以过去分词短语（'Backed by...'）开头，作为状语修饰语，表示主语所处的背景情况、原因或支持状态。在正式英文写作中，将过去分词短语前置能够营造流畅的衔接感，使次要信息自然地修饰主要从句的主语（'the outgoing secretary general'）。
Accompanied by senior diplomats, the foreign minister entered the summit hall to address the delegation.
在资深外交官的陪同下，外交部长走进峰会大厅向代表团发表演讲。
EN： The prepositional construction 'to + [noun phrase]' expresses accompanying circumstances or resulting reactions to an action, typically indicating how an audience reacted upon the subject's departure or arrival. Here, 'left the stage to rapturous applause' means departed while the audience responded with fervent applause.
中文： 介词结构「to + [名词短语]」用来表示伴随某个动作发生的反应或结果，常指出观众或听众在主语离开或到达时所展现的反应。在此处，「left the stage to rapturous applause」表示他在全场观众爆发热烈掌声的伴随下走下讲台。

指挥家在观众震耳欲聋的欢呼声中最后一次鞠躬致谢。
