1. 认识这个词（基础篇）
词：edge
英英释义：something that gives you an advantage over others
例句：Being able to speak good English is widely considered an edge in China.
2. 体会这个词 （进阶篇）
“edge”作名词最基本的意思是“边缘”“刀刃”，不过它也常可以引申表示“优势”，我们可以用它来替换“advantage”。
找工作时，有一定的实习或工作经验绝对是一种优势，我们就可以说：
自己翻译：If you have internship or working experience it must be an absolute edge,
👉 As far as job hunting is concerned, experience is an absolute edge.
思考：写的很简洁，找工作—-job hunting,
As far as overseas study is concerned, volunteer experience is an absolute edge.
使用“edge”时，最常见的一个搭配是“A has an edge over B”，表示 A 比 B 更好。比如，许多人选择在一线二线城市生活，因为相比其它城市，大城市的文化更多元，工作机会更多。
自己的翻译 ：Big cities have an edge over small cities, this is because big cities are more modern and have more opportunities.
👉 First- and second-tier citiesalways have an edge over other citiesin terms ofcultural diversity and job opportunities.
思考：很好的用in terms of 来连接，一线和二线可以用的表达：first and second tier cities; 工作机会—job opportunities.
另外，常和“edge”搭配的动词有“maintain”（保持）和“lose”（失去），比如我们想说美国的军事优势还在，不过移民优势正在减弱。我们就可以说：
自己的翻译：America military remains edge, but its immigration is losing edge.
👉 It seems the US is losing its immigrant edge, but it has maintained its military edge.（建议把这个句子背下来）
想表达在某人或某物在某一方面有优势，我们可以在“edge”前添加相应的形容词。比如《经济学人》在一篇讨论美国创新的文章中，就有这样一句话：
Indeed, the assumption that America is losing its innovative edge is open to question.
这句话的意思是：“的确，美国正在失去它的创新优势这个假设是可以质疑的。” 这句话的主语是“the assumption that America is losing its innovative edge”，这里的“innovative edge”就表示在创新方面的优势。（open to question表示质疑的）
3. 从认识到会用（作业）
