laggard
基础篇：meaning: a person who makes slow progress and falls behind others
进阶篇：laggard: 可数名词，意思是“落后者”， 从动词lag (落后)衍生而来。这个词是《经济学人》的常客，可以指一个人、一个公司、一支球队、一个国家。

《经济学人》的用例：
a）Britain's economy has gone from a leader to a laggard internationally, as GDP growth has slowed sharply.
想表达从领头羊变成了落后者，就可以直接用： go from a leader to a laggard
b) Indeed, half a millennium ago Europe might justly have been considered a laggard.
c) On its current path, the country will remain a growth laggard.
这句中，注意growth 虽然是名词，但是也可以用来修饰laggard. 可以多积累这类名词作修饰语的用法。
