The line you were given points at the phrase this word really lives in: to work like a Trojan means to work extremely hard, for a long time, without complaining. "She worked like a Trojan all weekend to finish the report." You can also say someone is a Trojan, meaning they are that kind of tireless worker — this use is warm and admiring, and sounds a little old-fashioned and British. Behind it is the ancient city of Troy: in the old stories the Trojans defended their city for ten years, so English took them as the picture of stubborn, unending effort.

The line you were given points at the phrase this word really lives in你拿到的這行字，指向的是這個字真正常用的片語：to work like a Trojan means to work extremely hardwork like a Trojan 意思是拚命工作，for a long time很長一段時間，without complaining而且毫無怨言。"She worked like a Trojan all weekend to finish the report."「She worked like a Trojan all weekend to finish the report.」（她整個週末拚命工作把報告做完）You can also say someone is a Trojan你也可以說某人 is a Trojan，meaning they are that kind of tireless worker意思是他們就是那種不知疲倦的工作者 — this use is warm and admiring這種用法是溫暖又帶著讚賞的，and sounds a little old-fashioned and British而且聽起來有點老派、有點英式。Behind it is the ancient city of Troy這個說法背後是古代的特洛伊城：in the old stories the Trojans defended their city for ten years在古老的故事裡，特洛伊人守城守了十年，so English took them as the picture of stubborn, unending effort所以英文就拿他們當作頑強、不停歇努力的象徵。

Two other uses are worth knowing because you will meet them more often. First, a Trojan horse is a trick — something that looks like a gift or looks harmless, and is let in, but has your enemy hidden inside it. People use it about ideas and policies: "the new rule is a Trojan horse for cutting wages." Second, in computers, a trojan (often written with a small t) is a program that pretends to be something useful so that you install it yourself, and then does harm.

Note the difference from the older phrase: work like a Trojan is praise, but Trojan horse and computer trojan are about deception.

Note the difference from the older phrase要注意跟這個較舊的片語有什麼不同：work like a Trojan is praisework like a Trojan 是稱讚，but Trojan horse and computer trojan are about deception但 Trojan horse 和電腦的 trojan 講的是欺騙。
