请客吃饭用英语

It is my treat .

请客 [词典] stand treat; entertain guests; invite sb. to dinner; give a dinner party; feast; [例句]这次由我请客。This is my treat.

treat you 我请你it's my treat 我请客treat somebody for dinner 请某人吃晚饭

正确的邀约表达Would you like to have lunch together?要不要一起吃个午餐?Do you want to have lunch together?你想要一起吃午餐么?Let’s have lunch together.我们一起吃午餐吧!英文中邀约一般就是这三种句式：Would you like to...Do you want to...Let’s...客气程度递减，但也不是说Let’s...就不客气，只是很随意啦~更随意的表达此外，lunch是可以做动词的，Let's lunch together也是一句很地道的表达

invite somebody to dinner
