In a euphoric way — doing something while feeling that overwhelming, floating happiness. It is a real word but a genuinely rare one, and it is worth knowing where it actually turns up. Mostly it modifies a verb of behaving or speaking: 'they cheered euphorically', 'she talked euphorically about the new job', 'the crowd danced euphorically in the street'. It can also sit in front of an adjective as an intensifier: 'euphorically happy', 'euphorically drunk'. What it does not do well is describe a state on its own; for that, English prefers the adjective — 'she was euphoric', not 'she felt euphorically'. Because it is long and low-frequency, native writers often step around it: 'they cheered wildly', 'she was euphoric as she described the job'. Recognise it when you read it; you rarely need it when you write.

欣喜若狂地、興奮到飄飄然地（副詞）。這個字很少用，多半修飾動作（歡呼、跳舞、談論）；描述狀態時英文人習慣改用形容詞 euphoric。
