it is been very nice talking to you请问为什么有个been

it is been very nice talking to you请问为什么有个been It's been nice talking to you.为什么用is不用has? It's been nice talking to you的意思 it is been nice to meet you?这是什么语态,为什么不是it was It is been nice meeting you.为什么meeting?而不用to meet? It was nice talking to you和It is nice talking to you用哪个? very nice talking to you 为什么要加ing very nice talking to you 这句话有语法错误吗 为什么是It's nice talking to you.而不是It's nice to talk to you. It's been good talking to are you sure you have to?it is been very late. You have been so nice to me为什么不能用you are so nice to me?
