Shipping
名词 shipping 涵盖船舶运输与更广义的物流配送：free shipping 指包邮，shipping delays 指延误；动词进行时表示正在发货的动作。
- “International shipping costs surged after the canal blockage.” (运河受阻后国际运费飙升。)
- “Orders placed before noon qualify for same-day shipping.” (中午前下单可享受当日发货。)
- “The port specializes in refrigerated shipping containers.” (该港口专精于冷藏集装箱货运。)
古英语 scip（船）演变成 ship；shipping 记录货物随船或车队移动的产业环节。
ship + -ing：既可名词化表示行业，也可作动名词。
跨境电商广告里的 free shipping 已成为全球消费者熟悉的短语；环保讨论亦涉及 shipping emissions。
- 固定搭配: “free shipping” (包邮), “shipping label” (快递面单), “shipping lane” (航运航线)
shop + ping？不对——记住 ship 装货鸣笛离岸，ing 表持续 industry。
