EN： Headlinese and Passive Reduction: In journalistic headlines, auxiliary verbs like 'is/was/has been' are omitted to save space and create urgency. Here, '[is/was] Found' functions as the main passive verb predicate, while 'Preserved' acts as a secondary participial complement specifying the state in which it was found.
中文： 新闻标题体（Headlinese）与被动式省略：新闻标题为了精简篇幅并营造即时感，常省略助动词（如 is / was / has been）。本句中 'Found' 实质上代表被动语态主谓语 '[was/has been] found'，而后方的过去分词 'Preserved' 则作为补语，描述被发现时所处的保存状态。
Rare painting thought lost for centuries recovered in private collection.
被认为失传数世纪的罕见画作在私人收藏中被寻回。
EN： Compound Adjectives with Hyphens: 'Leaf-Like' (noun + suffix/adjective) and '98-Million-Year-Old' (number + noun + adjective) function as pre-nominal modifiers. When measurement units form compound adjectives before a noun, the noun ('year') remains singular.
中文： 连字号复合形容词：'Leaf-Like'（名词 + 形容词后缀）与 '98-Million-Year-Old'（数词 + 单位名词 + 形容词）皆作为名词前置修饰语。需注意当计量单位在连字号复合词中作前置修饰时，名词（如 year）必须使用单数形式，不可加 s。

一名十岁的小孩在后院发现了一具蜘蛛状的化石。
EN： In scientific reporting, amber from northern Myanmar (Kachin State) is famous for preserving mid-Cretaceous (approx. 99-98 million years old) biodiversity with astonishing morphological detail, allowing scientists to observe soft tissues, fine hairs, and mimicry structures rarely preserved in mineral fossils.
中文： 在古生物科学报道中，来自缅甸北部（克钦邦）的琥珀闻名于世。这些约在 9900 万至 9800 万年前（白垩纪中期）形成的琥珀，能以极高的立体精细度保存生物软组织、细毛及拟态特征，这是传统矿物石质化石极难办到的。
EN： Past participial phrase as an adverbial modifier: The sentence opens with the past participle phrase 'Entombed in sticky resin...', which functions as a participial clause of manner/circumstance modifying the subject 'a 98-million-year-old praying mantis'. In journalistic and formal writing, placing non-finite clauses at the beginning sets a vivid scene before introducing the grammatical subject.
中文： 过去分词短语作状语修饰语：本句以过去分词短语「Entombed in sticky resin...」开头，作为分词从句修饰主语「a 98-million-year-old praying mantis」。在新闻与正式写作中，将非谓语动词短语置于句首有助于在引出主要主语前先营造出生动的背景氛围。
Trapped beneath layers of volcanic ash, the ancient Roman artifacts were discovered in pristine condition.
被困在数层火山灰之下，这些古罗马文物以近乎完好的状态被发现。
EN： Noun clause complement of a preposition ('what is now...'): The preposition 'in' takes the free relative clause 'what is now Myanmar' as its object. This construct is standard in historical, paleontological, and geographical contexts to specify past events occurring in a region that corresponds to a modern political territory.
中文： 介词后的名词从句（「what is now...」结构）：介词「in」接名词从句「what is now Myanmar」作宾语。在历史、古生物学或地理学领域中，此句型常用于指出发生在过去某个区域的地点，而该区域对应现今的某个现代国家或行政区。
Fossils were uncovered in what is now modern-day Mongolia.
化石是在现今的蒙古境内被发掘出来的。
EN： Present perfect passive with manner adverbial phrase: 'has been preserved in remarkable detail' combines the present perfect passive (emphasizing the present result of an ancient event) with the prepositional phrase 'in remarkable detail', which functions adverbially to describe the degree and quality of preservation.
中文： 现在完成式的被动语态与方式介词短语：「has been preserved in remarkable detail」结合了现在完成式被动语态（强调古老事件对现今所产生的结果），搭配介词短语「in remarkable detail」作副词修饰语，用以描绘化石保存的精细程度与品质。
The delicate insect wing has been preserved in extraordinary clarity.
那片脆弱的昆虫翅膀以极为清晰的状态被保存了下来。
EN： Burmese amber (or burmite) from northern Myanmar's Kachin State is one of paleontology's most critical windows into the mid-Cretaceous period (approximately 98-100 million years ago). Because tree resin enveloped plants and insects instantaneously in 3D without flattening them, specimens preserve microscopic anatomical structures that are rarely seen in rock impressions.
中文： 来自缅甸北部克钦邦的缅甸琥珀，是古生物学界研究白垩纪中期（约 9,800 万至 1 亿年前）最重要的窗口之一。由于黏稠的树脂能在三维空间中瞬间将昆虫与植物包裹，避免其被压平受损，因此往往能将微观的解剖构造保留得极为细致，这是传统岩石印痕化石难以企及的。
EN： The participial phrase 'closely resembling...' functions as a reduced relative clause modifying 'leaf-like structures' (equivalent to 'which closely resemble...').
中文： 分词短语「closely resembling...」在此充当简化关系从句，后位修饰先行词「leaf-like structures」（相当于「which closely resemble...」）。

Heavy rainfall flooded the runway, causing several flights to be diverted.
暴雨淹没了跑道，导致多个航班改降其他机场。
EN： In the phrase 'mantises mimicking foliage', 'mantises' serves as the subject of the gerund/participle 'mimicking' (acting as a noun phrase governed by the preposition 'of'). In formal contexts, this can also appear as a possessive ('mantises' mimicking').
中文： 在「mantises mimicking foliage」结构中，「mantises」是受介词「of」支配之分词/动名词短语「mimicking foliage」的逻辑主语，表达「螳螂拟态叶片」这件事（正式语体中亦可作所有格「mantises' mimicking」）。
There is little recorded history of predators adopting such deceptive tactics.
鲜少有捕食者采取此类欺骗性策略的记载历史。
EN： In biological and paleontological naming conventions, binomial nomenclature consists of a capitalized genus name followed by a lowercase species epithet (e.g., 'Selaginella grimaldii'), typically italicized. Additionally, 'foliage' is a collective term favored in scientific reporting to denote plant leaves broadly, especially in the context of camouflage and mimicry.
中文： 在生物学与古生物学的双名法命名规则中，属名必须大写，种小名则小写（如「Selaginella grimaldii」），书面通常采用斜体。此外，「foliage」在科学报道中常作为集合名词使用，泛指「植物枝叶/树叶」，特别常用于描述昆虫拟态与保护色伪装的语境。
EN： The sentence begins with a present participle phrase ('Describing the insect as...'), acting as an adverbial modifier indicating background context, action, or reason. The implied subject of the participle clause must match the subject of the main clause ('paleoentomologist Hongru Yang and colleagues') to avoid a dangling modifier.
中文： 句子开头使用现在分词短语（'Describing the insect as...'）作为状语修饰语，用来交代背景、伴随动作或原因。分词从句的隐含逻辑主语必须与主要从句的主语（'paleoentomologist Hongru Yang and colleagues'）保持一致，以避免产生悬空修饰（dangling modifier）。

气候学家强调，全球立即减少排放量已是势在必行。
EN： In scientific reporting, binomial nomenclature (such as Folimantis hyalinala) italicizes genus and species names, where the genus is capitalized and species lowercase. Referring to academic discoveries typically involves naming the lead author and acknowledging co-researchers with 'and colleagues' (equivalent to 'et al.' in citations), followed by the prestigious journal name (e.g., New Phytologist, founded in 1902).
中文： 在科学学术报道中，生物二名法（如透明叶螳螂 Folimantis hyalinala）通常以斜体书写，属名大写而种小名小写。介绍研究成果时，惯例常提及第一作者并以「and colleagues」（相当于论文引用中的 et al.）概括研究团队，同时引出发表该重要论文的高影响力学术期刊（如创刊于1902年的《新植物学家》）。
EN： Negative inversion occurs when a negative adverb or adverbial phrase (such as 'Never before', 'Rarely', or 'Seldom') is placed at the beginning of a clause for rhetorical emphasis. The auxiliary verb precedes the subject, mimicking question word order: [Negative Adverbial] + [Auxiliary] + [Subject] + [Main Verb].
中文： 否定倒装句（Negative Inversion）：当否定或半否定副词/短语（如 Never before, Rarely, Seldom 等）置于句首以达修辞强调时，主句须倒装，将助动词移至主语前面，形成类似疑问句的语序：[否定副词] + [助动词] + [主语] + [主要动词]。
Never before had the scientist witnessed such an extraordinary chemical reaction.
这位科学家以前从未见过如此不寻常的化学反应。
EN： Parenthetical insertion ('they noted') is set off by commas to attribute the claim or observation to the researchers without interrupting the main syntactic flow of the inverted clause.
中文： 插入语结构（Parenthetical Insertion）：'they noted' 通过逗号隔开插入句子中，用来说明观察或论述的来源，并不破坏原本倒装句的骨干语法结构。
This specimen, experts believe, represents a completely new evolutionary branch.
专家认为，这个标本代表了一个全新的演化分支。
EN： Passive infinitive construction 'is known to imitate' expresses general scientific knowledge or belief about an entity. The pattern 'Subject + be known + to-infinitive' conveys that a trait or action is universally recognized or documented.
中文： 'be known to + 原形动词' 表达已知事实或普遍认可的特征。本句以否定主语 'no living mantis species' 开头，表示『已知没有任何现生物种会……』。

已知没有任何陆生哺乳动物能在如此极端的大气压力下生存。
EN： In scientific reporting and academic papers, starting with an inverted negative like 'Never before' is a deliberate rhetorical device to highlight the unprecedented nature and high significance of a discovery. It elevates the register from standard observation to a historic scientific breakthrough.
中文： 在科学报道与学术期刊中，使用如 'Never before' 的否定倒装句型是一种刻意的修辞手法，旨在凸显该项发现具有空前绝后的科学价值与里程碑意义，将文章语域从一般的观察记录提升至历史性重大突破的高度。
EN： The verb 'offer' can take a double-object construction (ditransitive): 'offer + indirect object (recipient/field) + direct object (entity provided)'. In formal or academic writing, abstract fields of study like 'paleontology' can personify the recipient to mean 'provide scholars in this field with'.
中文： 动词「offer」可采双宾语结构（双及物动词），即「offer + 间接宾语（接收者或领域）+ 直接宾语（提供之事物）」。在正式或学术写作中，抽象学科（如 paleontology，古生物学）可拟人化作为接受者，意指「为该领域的学者提供……」。
