à la carte在法語裏是看菜單點菜的意思
法國外交部長Laurent Fabius說這句話的上下文如下:
“We want the British to be able to bring all their positive characteristics to Europe... but you can't do Europe a la carte," he told French radio.
"Imagine Europe is a football club and you join, but once you're in it you can't say, 'Let's play rugby'."
所以,分析過整體語境後,他的意思應該是:英國人不能把是否留在歐盟當作在飯店點菜那樣隨便。
另外,法國人的英語沒那麽標準,他們說的英語充滿法國式思維,因此,意會即可。
