Swooping
“Swooping” 指沿弧线快速俯冲后掠起，如 an eagle swooping down on its prey（老鹰俯冲捕食）或 a plane swooping low over the field（飞机低空掠过田野）。也可比喻人突然介入，如 swooping in to help（猛冲过来帮忙）。
- “The hawk went swooping over the meadow at dusk.” (黄昏时老鹰掠过草场上空俯冲。)
- “She came swooping into the room with armfuls of groceries.” (她抱着一大堆杂货冲进房间。)
- “Prices came swooping down after the holiday sale ended.” (假日促销结束后价格骤然回落。)
“Swoop” 可能源自中古英语 swopen（扫过），与 sweep（扫、掠）同源；意象是大弧度的俯冲与掠取。
词干 swoop（动词/名词，俯冲、猛扑）+ “-ing” 表示正在进行的俯冲或骤然行动。
自然纪录片与空战描写中 swooping 是高频词；口语 at one fell swoop 表示“一下子、一举”，来自莎士比亚。
- 固定搭配: “swooping down” (俯冲而下), “swooping in” (突然介入)
- 原形: swoop
- 名词: swoop
- 习语: at one fell swoop (一举)
“swoop” 像 sweep（扫过）+ loop（弧线）——沿弧线猛扫下来就是 swooping。
“A drone went swooping over the vineyard while the manager came swooping in with a fix for the irrigation bug.” (无人机掠过葡萄园俯冲时，经理也带着灌溉故障的修复方案冲了进来。)
