“上上下下”常见的英文表达有 “up and down” 或 “upwards and downwards”,具体使用需结合语境:
1、 “up and down”
含义:表示动作或状态在垂直方向上的反复,或情绪、状态的不稳定波动。
例句:
The elevator moved up and down all day. (电梯一整天都在上下移动。)
His mood went up and down after the news. (听到消息后,他的情绪起伏不定。)
2、 “upwards and downwards”
含义:与“up and down”类似,但更强调方向性,常用于描述物理运动或抽象的波动。
例句:

选择建议:描述物理运动(如电梯、飞行)时,两者均可,但“up and down”更常用。
描述情绪、状态或抽象波动时,优先用“up and down”。
若需强调方向性,可选用“upwards and downwards”。
