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 intodigitisation.
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.
3. 怎样学会使用这个词？
1）翻译下面的句子：
很多中国互联网公司开始扩展海外业务，寻求新的增长点。
Many Chinese Internet companies start to expend overseas operations and find new growing point.
（参考翻译：Many Chinese Internet companies have begun new operations in foreign markets in pursuit of further growth.
或 In the hope of growing further, many Chinese Internet companies have set up new operations in foreign countries.）
2）结合自己的生活、学习、工作、兴趣等，想象在什么语境下会用到这个表达。先简要描述这个场景，再造句。
例子： 公司打算开展新业务来促进经济增长。
场景 ：The company plans to set up new operations in order to promote economic growth.
