有東西來了，所以做出動作
這一群是核心畫面的兩個大小：一個是「做點什麼」（不一定用嘴巴），一個是「說點什麼」。差別只在回出去的那一下是行動還是話語。
react · verb · B2
To do something because of something that has been said or done to you.
回應
核心畫面
Picture a ball coming at you: something reaches you first, and then something comes back out of you. Respond can be thought of as that second movement — the one that only exists because something arrived. It always points back at what caused it, which is why respond so often sits next to to: you respond to a question, to a fire alarm, to a kind of medicine. Nothing gets called responding unless something came in first.

可以想成一顆球朝你飛過來：先是有東西到了你這裡，然後有東西從你這裡回出去。respond 的畫面比較像後面那個動作——它之所以存在，完全是因為前面有東西先來了。它永遠指回那個「來的東西」，所以 respond 後面常常跟著 to：respond to a question（回應問題）、respond to a fire alarm（對火警警報做出反應）、respond to a medicine（對藥物有反應）。沒有先來的那一下，就沒有 respond。Two branches
身體對治療起了反應
同一個「有東西進來、有東西回出去」的畫面，只是這次回應的不是人，是身體。藥進去了，身體給出反應——所以英文照樣用 respond，不必換字。
