You can picture a small truck doing its round: the same road every day, one short stop after another, back at the same time each morning. Two things come out of that picture — it stops a lot, so it is slow; and it repeats, so whoever drives it stops having to think.

可以想成一台每天跑同一條路線的車:時間固定、路線固定,一家停一下、再一家停一下,早上出門,中午前回來。(這只是幫助記憶的畫面,不是在說這個詞的來歷。)從這個畫面會長出兩件事:一是它停很多站,所以慢;二是它天天重複,所以跑的人愈跑愈熟,最後不用動腦。英文的三個用法,各自抓住了其中一邊。
