腳踩下去，引擎活過來
這一家就是核心畫面本身，只是鏡頭一次對準動作、一次對準零件。
verb · B2
To start the engine of a motorcycle or scooter by pushing a small lever down hard with your foot.
腳踩發動（機車）
核心畫面
Picture an old standing silent by the road. The rider swings out a short metal lever near one foot, stands up a little, and stamps down hard. One sharp push, and an engine that was dead is running. Hold that picture and the whole word is in it: a single shove that turns something still into something moving. The push lasts a second; what it starts keeps going by itself. That is why the same word can name the lever, the stamp of the foot, and the small event that gets a stalled plan moving again.

可以想成一台熄火的舊機車停在路邊。騎士把腳邊那根小鐵桿撥出來，稍微站起身，用力往下一踩。就那一下，剛才還安靜的引擎轟一聲活了過來。這個畫面大概就裝得下這個字的全部：短短一下用力的推，讓靜止的東西開始動。推的時間很短，被推動的東西之後自己跑。所以同一個字可以指那根桿子、指腳踩的動作，也可以指讓一個卡住的計畫重新開始的那件小事。Two branches
給停住的事情一腳
把機車換成一件停著不動的事：經濟、計畫、事業、冷場的討論。踩下去的那一腳，換成一筆錢、一個決定或一場小活動。這是概念上的延伸，不是在說歷史上誰先誰後。
