一位听众想知道 “trace”、“source” 和 “track” 这三个词该如何使用。这三个单词都可以用于描述产品来源、供应链及物流运输等场景，但含义和用法各有侧重。“Trace” 强调追溯来源或过程，“source” 表示 “获取” 或 “采购”，“track” 则表示 “追踪” 或 “跟踪”。本期节目将通过具体例子，带你辨析这三个容易混淆的单词。
So, Georgie, in this case, we are looking at these words as verbs.
Where and how can we use them?
Hmm, well let's think about my food delivery subscription.
I said, from my research, I managed to trace the ingredients back to a few small farms.
That means I identified the source of the ingredients.
I discovered where they came from.
trace的意思就是追溯、探寻某物的来源。 比如,刚刚Georgie就用trace这个词来描述他通过调研追溯了他订购的食品原料具体来自哪些农场的过程。 也就是说,他成功找到了the source of the ingredients,原料的来源。 在这里,单词source是一个名词,意思是来源、源头。 But Georgie, you said that the food delivery company sources their ingredients from these farms.
So source in this case means to get or to obtain.
The meaning is quite different.
So let's hear another example to hear the difference again.
Sure.
I love the coffee in my local café, so I wanted to find out where they get their coffee beans from.
I looked into it and I traced the beans back to a supplier in Brazil.
I found out where they came from.
So, now I know that the café sources their beans from Brazil.
They get their beans from Brazil.
And that's how we can use source as a verb.
我们也可以把source当作动词来使用, 意思是获取或采购某种原材料、物品或者信息。 就拿George刚才举的例子来说, 他喜欢的一家咖啡店会从巴西source采购他们使用的咖啡豆。 I think that all sounds pretty clear.
Now, what about track? You said the food delivery company has an app which allows you to track the delivery.
Yes, track means you follow something as it moves or changes.
Think about the app I was talking about.
It lets me see when my fruit and vegetable delivery has arrived at their warehouse.
Then I can watch as the delivery van drives to my city and then around my neighbourhood before it finally arrives at my house.
I track the delivery.
就是说track和trace的含义有所不同,表达的是追踪沿着某条信息或线索持续地观察一样东西的位置或状态。 比如在收发快递时,查看包裹所在的位置和状态的服务和功能,就叫做track或者tracking。 你正在收听的是BBC英语教学制作的你问我答节目。 在本期节目中,我和Georgie正在编辑三个和追溯追踪有关的单词trace, source和track。 从含义上来讲,如果我们想表达查明某样东西的来源, 特别是像这位听众在问题中提到的给农产品溯源这个说法, 那么最合适的词可能是trace, 比如tracing the source of agricultural products。 Trace指的是通过调查、弄清楚或发现某样东西的来源、事情发生的原因等等。 与之相比, source指的是从某个地方获得或采购某样东西,而 track的意思则是持续地观察和追踪某样东西的移动过程或变化。 那么Georgie,这三个词在实际使用中又有什么特点呢?
