Main clause: 'French President... have instructed... to continue work'. Then a present participial phrase 'countering speculation that...' acting as an adverbial modifier. Within that, 'that the program had collapsed' is a noun clause serving as the object of 'speculation'. The use of 'countering' is a participial phrase, and 'respective' is a determiner.主句為「法國總統...已指示...繼續工作」，後接現在分詞短語「countering speculation that...」作為狀語修飾。其中「that the program had collapsed」是名詞子句，作「speculation」的賓語。使用「countering」為分詞短語，以及「respective」限定詞。
Main clause: 'The FCAS program... is intended to develop...'. The subject is modified by a past participial phrase 'initiated in 2017' (reduced relative clause). The object 'a next-generation combat air system' is further modified by a present participial phrase 'comprising crewed fighter jets and armed drones', which itself contains another present participial phrase 'operating under a common digital network' modifying 'drones'. This creates a layered structure of reduced relative clauses.主句為「FCAS計劃...旨在開發...」。主語由過去分詞短語「initiated in 2017」修飾（縮減關係子句）。賓語「a next-generation combat air system」由現在分詞短語「comprising crewed fighter jets and armed drones」修飾，該短語內又包含另一現在分詞短語「operating under a common digital network」修飾「drones」，形成層疊的縮減關係子句結構。
Main clause: 'The project has been stalled'. Followed by a complex prepositional phrase 'due to a public dispute... over leadership...'. Within that, 'between France's Dassault Aviation and Airbus' is a prepositional phrase, and 'which represents Germany and Spain' is a non-restrictive relative clause modifying 'Airbus'. The phrase 'over leadership of the core fighter element' is another prepositional phrase indicating the subject of the dispute.主句為「該項目已停滯」。後接複雜介詞短語「due to a public dispute... over leadership...」。其中「between France's Dassault Aviation and Airbus」是介詞短語，「which represents Germany and Spain」是非限制性關係子句修飾「Airbus」。短語「over leadership of the core fighter element」是另一個介詞短語，指明爭議的主題。
Main clause: 'Macron stated that...'. The object is a noun clause 'that the project was not dead'. Then a present participial phrase 'adding that...' which contains another noun clause 'that he and Merz had a constructive discussion and tasked defence ministries with exploring multiple areas of cooperation'. Within that noun clause, there is a coordination of two verb phrases: 'had a constructive discussion' and 'tasked defence ministries with exploring...'. Finally, a reduced relative phrase 'not limited to FCAS' modifies 'areas of cooperation'.主句為「馬克龍表示...」。賓語是名詞子句「that the project was not dead」。後接現在分詞短語「adding that...」，其中包含另一名詞子句「that he and Merz had a constructive discussion and tasked defence ministries with exploring multiple areas of cooperation」。在該名詞子句內，有兩個動詞短語的並列：「had a constructive discussion」和「tasked defence ministries with exploring...」。最後，縮減關係短語「not limited to FCAS」修飾「areas of cooperation」。
Main clause: 'The failure of FCAS would represent a major setback...'. The verb 'would represent' is in the conditional mood, indicating a hypothetical outcome. Then a subordinate clause introduced by 'as' (causal conjunction): 'as the program is seen as a bellwether...'. Within that clause, 'amid shifting geopolitical circumstances' is a prepositional phrase. The noun 'bellwether' is a high-lexical-density term.主句為「FCAS的失敗將代表...重大挫折」。動詞「would represent」使用條件語氣，表示假設結果。後接由「as」（因果連詞）引導的從句：「as the program is seen as a bellwether...」。該從句內，「amid shifting geopolitical circumstances」是介詞短語。名詞「bellwether」為高詞彙密度詞彙。
