“向下的”常见的英文表达有 downward、downwards(英式英语中较常用,美式英语里相对少见,但两种形式在很多语境下可互换) 以及 down(较为口语化、简洁的表达 )。具体使用示例如下:
downward:形容词,常用于描述物体、趋势、运动等方向朝下。例如:The plane began its downward descent.(飞机开始向下俯冲。)There has been a downward trend in sales this year.(今年销售额呈下降趋势。)
downwards:副词,与downward意思相近,但更强调动作或方向朝下。例如:The ball rolled downwards the hill.(球顺着山坡向下滚。)He gestured downwards with his hand.(他用手朝下示意。)
down:既可作形容词、副词,也可作介词等,在表示“向下的”这一含义时,用法较为灵活和口语化。例如:The cat jumped down from the tree.(猫从树上跳了下来。)Keep your head down.(把头低下来。)
