1. 这是个什么词？

词：operation

英英释义：a business, company, or organization

例句：Y Combinator, a Silicon Valley-based start-up accelerator, set up its operation in China at the end of last year.

2. 为什么选这个词？

“operation”可以作可数名词也可以作不可数名词，最常见的意思是“运营、行动”。还有一个比较常见的意思是“公司、业务”，可以用来替换 company 和 business，增强用词的多样化。下面来看几个例子。

硅谷创投加速器巨头 Y Combinator 去年年底在中国开设了业务，就可以说：

Y Combinator, a Silicon Valley-based start-up accelerator, set up its operation in China at the end of last year.

《纽约客》一篇文章的开头句中出现了 operation:

It was a hot February morning at Wish Farms, a large strawberry-growing operation outside Plant City, Florida.

根据语境我们知道这里的 operation 是草莓种植园的意思，因为 Wish Farms 中已经出现了 farm，为了避免重复，因此用了 operation 进一步解释说 Wish Farms 是什么。

最后，来看看《经济学人》文章中用到的几处 operation：

a) As Sanjay Gupta, who runs Disney’s direct-to-consumer operations in India puts it, “there’s a second and third TV in every home.”

b) Under António Horta-Osório, its chief executive since 2011, Lloyds has ditched almost all its foreign operations, narrowed its product range and (like many other banks) poured money into digitisation. 自2011年以来，在首席执行官安东尼奥•奥尔塔-奥索里奥(Antonio Horta-Osorio)的领导下，劳埃德几乎放弃了所有的海外业务，缩小了产品范围，并(像许多其它银行一样)将大量资金投入数字化。

c) By the time Yahoo’s bosses sold its operations to Verizon in 2017, keeping mainly its Alibaba stake, investors treated the stock as a back door to the Chinese firm.
