你们没吃饭用英语怎么说

你们没吃饭用英语可以说 "You haven't eaten yet."
这个表达来源于英语中 "eat" 的意思是 "吃饭"，所以 "You haven't eaten yet" 就是在说 "你们还没吃饭"。
例句：
"You haven't eaten yet? Come on, let's go to the cafeteria and get some food." (你们还没吃饭吗？快点，让我们去食堂吃点东西吧。)
"I'm sorry, but I'm really not hungry. I already ate before the meeting." (对不起，我真的不饿。会议开始前我已经吃了。)
"Wow, you've eaten a lot! Are you sure you're not full yet?" (哇，你吃了好多啊！你确定你还没吃饱吗？)
