"抓住机会"的英文表达是"seize the opportunity"。这个表达的来源可能是源自于拿破仑·希尔的名言"凡是有机会者，唯有抓住机会才能成为英雄。"（"Opportunity is missed by most people because it is dressed in overalls and looks like work."）。一些例句如下：

You have to seize the opportunity when it presents itself.

John was able to seize the opportunity and start his own business.

The company is looking for employees who can seize opportunities and take initiative.
