Developed
“Developed”是一个形容词，主要有两个含义：
- 发达的：高度发展、先进的
- 成熟的：成熟、完善的
- The developed country had good infrastructure. (发达国家有良好的基础设施。)
- The developed skills were impressive. (发达的技能令人印象深刻。)
- The developed area was prosperous. (发达的地区很繁荣。)
“Developed”来自动词 “develop”（发展），加上后缀 “-ed”（过去分词形式，用作形容词）。
- 前缀：de-（离开）
- 词根：velop-（包裹）
- 后缀：-ed（过去分词形式）
“Developed”常用于描述高度发展、先进的国家或地区，在经济学、政治和日常对话中经常使用。
- 动词形式：develop（发展）
可以将 “developed” 与 “develop”（发展）联系起来，“-ed” 后缀表示”发达的”。
When I visited a developed country, I was amazed by the infrastructure - good roads, reliable public transportation, modern buildings everywhere. The developed economy meant people had better opportunities and higher standards of living. Being developed doesn’t just mean having money - it means having systems and services that work well for everyone.
当我访问一个发达国家时，我对基础设施感到惊叹——良好的道路、可靠的公共交通、到处都是现代建筑。发达的经济意味着人们有更好的机会和更高的生活水平。发达不仅仅意味着有钱——它意味着有系统和为每个人良好工作的服务。
