當你想對一箇外國人說“辛苦了”，你可以根據不同的情境選擇不同的表達方式：
當某人幫助了你，你可以表達感激之情：
"I appreciate it."
"I appreciate your efforts, thank you."
"I couldn't have done that without you/your help."
在團隊完成一項工作後，你可以對大家的努力表示感謝：
"I appreciate everyone's hard work/efforts into finishing this project on time."
在節日時，你可以對父母或師長表達感激：
"I'm so grateful for you, mom!"
"I'm so grateful that I can have you as a dad!"
"You're the best teacher ever!"
"Thanks for taking care of me all these years!"
對於工作中的合作，完成一項任務後，可以說：
"Good job, we did it."
"Great job, you did it."
"Fantastic job."
對於老師或長輩，你可以說：
"You are the best teacher anyone could ask for!"
"I'm so grateful for you!"
請注意，直接翻譯成"You're tired!"是不恰當的，因爲這種說法在英語中並不表達“辛苦了”的真正含義，而是可能被誤解爲對方累了。正確的表達應該側重於感謝和認可對方的付出，如上述的各種表達方式所示。
