EN： The modal auxiliary 'could' is used here to express tentative possibility or potential in academic/formal reporting, avoiding overly absolute claims. 'Serve as' is a phrasal verb meaning to function in a particular role or capacity.
中文： 情態助動詞「could」在此處用於表達推測性可能或潛在能力，為學術或新聞報導中常見的審慎表達（hedging），以避免斷言過於絕對。「serve as」則是常用片語動詞，意為「充當、擔任……的角色或功能」。

社區中心在嚴重的冬季風暴期間可以充當緊急避難所。
EN： The past participle phrase 'conducted in two London neighbourhoods' acts as a reduced relative clause (short for 'which was conducted in...') post-modifying the noun phrase 'a year-long field study'.
中文： 過去分詞片語「conducted in two London neighbourhoods」作為後位修飾語，修飾前面的名詞片語「a year-long field study」，相當於省略了「which was」的關係子句簡化結構。

EN： In the UK, residential architecture frequently features 'front gardens' separating houses from roads. In recent decades, many homeowners paved over these gardens to park cars ('paving over of front gardens'). This study touches on an ongoing British urban debate regarding how the loss of domestic greenery exacerbates pollution and urban heat island effects.
中文： 在英國住宅建築中，聯排房屋（terraced houses）或半獨立別墅前常設有小型的「前院花園」（front garden）。近幾十年來，許多居民為了停車便利將花園鋪上柏油或地磚（稱為「paving over」）。本研究回應了英國近年關於家庭花園綠化流失如何加劇城市空氣污染及熱島效應的公共政策爭議。
EN： The sentence begins with a perfect participial clause ('Having measured...'). The perfect participle ('having' + past participle) emphasizes that an action was completed prior to the action in the main clause ('found'). The logical subject of this participial phrase must match the subject of the main clause ('the research team').
中文： 句首使用了完成分詞子句（'Having measured...'）。完成分詞（having + 過去分詞）用於強調該動作在主要子句動作（found）發生之前便已完成。此分詞子句的邏輯主詞必須與主要子句的主詞（the research team）保持一致。
Having analyzed the data thoroughly, the committee published its final report.
在徹底分析數據之後，委員會發布了最終報告。
EN： The verb 'found' is followed by a nominal 'that'-clause serving as its direct object ('that plots with hedges and plentiful vegetation recorded the lowest levels'). Inside this noun clause, 'plots with hedges and plentiful vegetation' functions as the subject, modified by a prepositional phrase with compound noun objects.
中文： 動詞「found」後接由「that」引導的名詞子句作為受詞（'that plots with hedges...'）。在該子句內部，「plots with hedges and plentiful vegetation」擔任主詞，並由帶有複合受詞的介系詞片語「with...」修飾。
Recent studies suggest that individuals who maintain a balanced diet experience fewer health issues.
最近的研究表明，保持均衡飲食的人遇到的健康問題較少。
EN： In the UK, front gardens are an integral feature of residential streetscapes, traditionally separating houses from the pavement. However, in recent decades, many homeowners have paved over their front gardens to create off-street parking, a trend that environmentalists caution against because it accelerates surface runoff and eliminates natural vegetation that traps vehicle emissions.
中文： 在英國，前花園（front garden）是住宅街景的重要特色，傳統上作為房屋與人行道之間的緩衝帶。然而近年來，許多屋主為了私家車停車位而將前花園鋪上水泥或磚石（paved over）。環保人士對此提出警告，指出失去天然樹籬與植被會加速地表逕流，並剝奪吸收道路廢氣的天然屏障。
EN： Sentence adverbs (viewpoint adverbs) like 'Strikingly' modify the entire clause rather than a single verb or adjective. Placed at the beginning of the sentence followed by a comma, it expresses the speaker's stance or assessment of the information—specifically highlighting how surprising or dramatic the following fact is.
中文： 像「Strikingly」這類的句子副詞（觀點副詞）用於修飾整個子句，而非單一動詞或形容詞。放在句首並以逗號隔開時，能傳達說話者對該訊息的評價或態度，特別是用於強調後續事實的驚人或顯著程度。

令人稱奇的是，該名病患在兩週內就完全康復了。
EN： 'Up to' is used as an adverbial quantifier before numbers or percentages to indicate an upper limit or maximum ceiling ('as much/many as'). Note that 'particle pollution' is an uncountable noun here, which requires the comparative quantifier 'less' rather than 'fewer'.
中文： 「up to」作為副詞性修飾語置於數字或百分比前，表示上限或最高可達的程度（意為「高達……」）。此外，由於「particle pollution（懸浮微粒污染）」在此為不可數名詞，因此比較級使用「less」而非修飾可數名詞的「fewer」。
The new insulation can cut heating costs by up to 30% compared to traditional materials.
相較於傳統建材，新型隔熱材料最高可降低 30% 的暖氣支出。
EN： The subordinating conjunction 'while' introduces an adverbial clause of contrast (adversative while), functioning similarly to 'whereas'. It sets two concurrent facts or trends side by side without expressing a temporal relationship.
中文： 從屬連接詞「while」在此引導表對比的副詞子句（對比 while），功能相當於「whereas」，用於並列兩項同時存在的事實或趨勢進行對照，並非表示時間上的「當……之際」。
Sales of electric vehicles surged, while traditional petrol car purchases dropped sharply.
電動車的銷量大幅增長，而傳統燃油車的購買量則急劇下滑。
EN： In the UK, many homeowners historically paved over their front gardens to create off-street parking spaces (driveways). This trend has sparked major environmental debates concerning urban flood risks and localized air pollution, prompting environmental researchers to study the protective benefits of preserving natural lawns and hedges.
中文： 在英國，許多屋主過去傾向將前院鋪上石磚或水泥改造成私人停車位（driveway）。然而，這一趨勢近年來引發了關於都市內澇風險與微區域空氣污染的激烈環保辯論，促使科研團隊著手調查保留天然草坪與綠籬對阻擋污染的實質益處。
EN： Negative inversion: When a negative or restrictive expression like 'Not only' is placed at the beginning of a clause for emphasis, subject-auxiliary inversion occurs (auxiliary verb + subject + main verb). The correlative second clause ('but...') generally maintains normal subject-verb order.
中文： 否定倒裝句：當「Not only」等否定或限制性副詞片語置於句首以加強語氣時，該子句的主詞與助動詞必須倒裝（助動詞 + 主詞 + 原形動詞）。後方對應的「but...」子句則通常維持正常的主述語序。

該策略不僅降低了營運成本，還提升了顧客滿意度。
EN： Participle clause expressing result/consequence: The present participle phrase ', effectively filtering...' functions as a non-finite adverbial clause, modifying the entire preceding compound clause to show an immediate outcome or resulting state.
中文： 現在分詞片語作結果狀語：逗號後接的「, effectively filtering...」為現在分詞片語，修飾前面的整個複合句，用以表示主句動作所帶來的直接結果或後續伴隨狀態。
The factory installed advanced scrubbers, drastically cutting emissions into the atmosphere.
該工廠安裝了先進的洗滌器，大幅削減了排放至大氣中的污染物。
EN： In the UK, urban domestic gardens ('front gardens' and 'back gardens') form a major portion of urban green infrastructure. Due to high vehicle emissions in densely populated cities like London, environmental science frequently explores how roadside vegetation can serve as natural biofilters, contrasting with modern trends of paving over front gardens for car parking.
中文： 在英國，住宅自帶的前庭（front garden）與後院是都市綠色基盤的重要組成部分。倫敦等大城市面臨嚴重的車輛排氣污染，環境科學研究極為重視路旁植栽作為天然「生物過濾網」的價值，這也與近年民眾為了方便停車而將前庭鋪成水泥地的都市改建趨勢形成鮮明對比。
EN： "Given that..." functions as a complex subordinating conjunction meaning "taking into account that" or "because of the fact that". It introduces an established condition, fact, or premise from which a logical conclusion or evaluation is drawn in the main clause.
中文： 「Given that...」作為複合從屬連接詞使用，意為「考慮到……」或「鑑於……的事實」。常用於引出已知的事實、前提或客觀背景，並在此基礎上於主句導出邏輯推論或重要評估。

考慮到再生能源的成本大幅下降，投資太陽能現在在經濟上切實可行。
EN： "Compared with / to..." is a reduced participial phrase used parenthetically to contrast statistics or entities. In formal English, "compared with" is traditionally preferred when highlighting concrete differences between similar items.

EN： The pattern "the implications for [something] are considerable" uses the formal noun "implications" (far-reaching effects/consequences) followed by the preposition "for" and the predicate adjective "considerable" (notably large or significant), expressing substantial real-world impact.
中文： 句型「the implications for [某事物] are considerable」使用正式名詞「implications」（深遠影響、潛在後果），後接介系詞「for」指明受影響對象，並搭配表語形容詞「considerable」（相當大的、顯著的），用以表達其具有重大的現實意義。

人工智慧對勞動市場的潛在影響相當深遠。
EN： In the UK, "domestic gardens" (especially front and back gardens of terraced or semi-detached houses) make up a surprisingly large proportion of urban green space. "Greater London" refers to the administrative area encompassing the 32 London boroughs and the City of London, while "Cardiff" is the capital city of Wales. Urban planners in the UK increasingly view private gardens as vital infrastructure for biodiversity, climate resilience, and flood control.
中文： 在英國，「domestic gardens」（私人庭院，特別是連棟透天或雙拼住宅的前後庭院）佔了城市綠地的極大比例。「大倫敦」指的是包含 32 個倫敦自治市及倫敦市的行政區域，而「卡地夫」則是威爾斯的首府。當代英國都市規劃者日益將私人庭院視為維護生物多樣性、應對氣候變遷與防洪的重要基礎設施。
EN： The verb 'urge' expresses recommendation or demand and triggers the mandative subjunctive in the following 'that' clause. In formal British and American English, the subjunctive uses the base form of the verb regardless of the subject (e.g., 'that incentives be introduced', omitting 'should').
中文： 動詞「urge」表示強烈建議或敦促，其後接的「that」名詞子句須使用祈使/虛擬語氣（Mandative Subjunctive）。在正式書面語中，子句動詞須使用原型動詞（此處為被動式的「be introduced」，省略了情態助動詞 should）。
Health officials urged that strict hygiene protocols be maintained in all public spaces.
衛生官員強烈呼籲所有公共場所均應保持嚴格的衛生規範。
EN： The relative clause 'which could also ease...' is non-restrictive (preceded by a comma), providing supplementary information about the whole antecedent idea ('to preserve such vegetation' or 'such vegetation'). 'Which' refers back to preserving such vegetation, functioning as the subject of the clause.
中文： 非限定關係子句「, which could also ease...」由逗號隔開，提供補充說明。在此句中，關係代名詞「which」的先行詞為前述的整個概念（「保留這類植被」），並在關係子句中擔任主詞。

沿海城鎮面臨極端風暴所加劇的海平面上升帶來的日益增加的風險。
EN： In British urban ecology and policy discourse, the loss of 'front gardens' to paved driveways has become a significant environmental issue. Paving reduces drainage (increasing flood risks), elevates the urban heat island effect, and eliminates roadside air pollution barriers, leading researchers and local councils to advocate for policy incentives and green-retention mandates.
中文： 在英國城市生態與都市規劃討論中，居民為了停車將「前院花園」鋪平為水泥地或柏油路面的現象已引起重大環保爭議。鋪面化降低雨水滲透（加劇水患風險）、加劇城市熱島效應，並消除了阻擋道路空污的天然屏障；因此學界與地方議會極力提倡以政策激勵措施來維護民宅植被。
