Picture a route drawn on a map, and one mark at the front of it. That mark is not the best part of the route and it is not where anyone wants to stay; it is simply where the line begins, so that everything else has somewhere to run from. English uses that mark for real ground, where a walk or a race begins, and for thinking, where a fact or a question is set down so a discussion can move off it.
可以想成地圖上畫好的一條路線，前端有一個記號。那個記號不是路上最精彩的地方，也沒有人打算停在那裡。它的功用只有一個：讓後面的線有地方可以往外走。英文把這個記號用在真的土地上，就是健行或路跑出發的那一點。用在想法上，就是先放下一個事實或一個問題，讓討論可以從那裡動起來。所以說某樣東西是 starting point，通常不是在說它對，而是在說「我們從這裡開始」。
