这是一段听力里的句子,上下文是：
(Mrs.Lee makes a telephone call to Andy's mother,Mrs.Cho.)
Mrs.Lee:Hello,may I please speak with Mrs.Cho?
Mrs.Cho:This is she.May I ask who is calling?
Mrs.Lee:Yes,it's Mrs.Lee,Michael's mother.
Mrs.Cho:Oh,Hello!How are you?
Mrs.Lee:I'm fine,thank you.How have you been?
Mrs.Cho:Fine,thank you.May I ask you a question?
Mrs.Lee:Of course.
这是不是一个病句 怎么不是THIS IS HER．用宾格?
再随便也不能这么随便吧!
