1. 这是个什么词？
词：home-grown
英英释义：belonging to one's own particular locality or country
例句：In recent years, home-grown technologies such as missiles, spacecrafts, and trains have slowly caught up with the best in the world.
2. 为什么选这个词？
“home-grown”是形容词，也可以写作 homegrown。意思是“本土的、国产的、土生土长的”。如果用它的本意，后面一般接蔬菜、水果等，不过很多时候用的是它的引申义，后面往往接 talent, product, star, brand 等词。在有的语境中，也可以用 home-grown 来替换 local。下面通过几个例子来掌握这个词。
我们在新闻中经常听到“自主研发的导弹、航天器、列车”等，其实都可以用 home-grown 表示“自主研发的”。比如：
In recent years, home-grown technologies such as missiles, spacecrafts, and trains have slowly caught up with the best in the world.
Justin 老师几年前在一篇关于创新的文章中写道：
Innovation leaders also tend to be open to and tolerant of new and challenging ideas. They embrace the best brain, home-grown and airborne alike. Korea and Japan, for example, educate and keep their native-born talent. America and much of the rich world are remarkably resourceful: they produce their own as well as attract clever immigrants.
这里面 home-grown 修饰的就是 brain，即本地人才，和第三句中的 native-born 一个意思；第二句中的 airborne 对应第四句中的 immigrants。由此可见 home-grown 可以丰富我们表达的多样性。
Justin 老师在写瑞幸咖啡的文章中，介绍这个本土新品时也用到了 home-grown:
Unlike Starbucks, the Seattle-born global juggernaut, Luckin is a home-grown novice, despite its English name and sleek design.
这句中，home-grown 修饰的是 noivce（新手），说明瑞幸咖啡是国产新品牌，home-grown novice 对应前面的 global juggernaut（国际巨头）。
下面来看《经济学人》中的几个例子：
1）Texas has thrived by importing skilled Americans, but it needs to cultivate its home-grown workforce, too.（home-grown 对应 importing）
2）Instead, China unveiled another supercomputer, Sunway TaihuLight, that led that ranking in 2016 and 2017—this time powered entirely by home-grown microprocessors.
3）They will push home-grown operating systems and technical standards, and direct vast resources and the country’s sharpest minds to developing advanced technologies.（这里的主语 they 指的是 Chinese leaders）
3. 怎样学会使用这个词？
1）翻译下面的句子：
很多人以为名创优品（Miniso）是日本品牌，但其实是国产品牌。
（参考翻译：Many have mistakenly taken Miniso to be a Japanese brand, whereas it's home-grown.)
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。
The home-grown genetic technology amazed the world.
