What would you likefor lun?与what do you have for lunch的区别

请说一下What would you likefor lun?与what do you have for lunch的区别

would you like是问你的倾向，问你的喜好。你喜欢lunch吃啥？你倾向于哪种食物？你会吃啥？

do you have 是问你lunch点了什么，吃了什么了。

举个例子：你问同学 what would you like for lunch，你同学说要吃鸡腿。然后你们两个在食堂打饭。打完之后你问他what do you have，同学说吃青菜呢，鸡腿都卖完了。或者你们吃着（吃完），路人甲过来问what do you have for lunch，你同学会回答，吃青菜呢。
