quite a beautiful girl还是a quite beautiful girl我觉得都可以啊一定要quite a beautiful 能不能给出具体解释

quite a beautiful girl
'a' is specific. so you can have "a beautiful girl is required for the job". But "she is a beautiful girl"
She is a flirt. She is dirty. She is quiet. She is beautiful. She is angry. She is an angry girl.

用后面的是错的，如果一定要说为什么，那就是英语和汉语的语法差异吧

quite a beautiful girl 对
quite 与不定冠词连用时,quite在前,不定冠词在后.
