“green-eyed monster”出自莎士比亚的戏剧《奥赛罗》。中国人妒忌的时候会眼红，英语国家的人却会眼绿——所以英文green-eyed（绿眼）即“妒忌的”，green-eyed monster（绿眼怪物），即“妒忌；嫉妒”。

【例句】
The green-eyed monster made her suffer when she learnt that you had moved into a socially better neighborhood.
听说你搬进了社会地位较高的人居住的住宅区，她嫉妒得不得了。

But people would be deterred from acting on the green-eyed monster.
但人们将被制止因妒忌而行事。
