Is that you, John?

JOHN: Is that you, Jean?

JEAN: Yes, speaking.

JOHN: Tell Mary we'll be late for dinner this evening.

JEAN: I'm afraid I can't. I'm not Mary. I'm Jean.

JOHN: Oh, I'm sorry... Err... Is Mary there?

JEAN: No, she isn't here.

JOHN: Can you tell her to call me?

JEAN: I'm sorry. I don't know her.

约翰：是你吗，琼？

琼：是的，请讲。

约翰：你告诉玛丽，今晚吃饭将晚到一会儿。

琼：恐怕我办不到。我不是玛丽。我是琼。

约翰：噢，对不起……呃……请问玛丽在吗？

琼：不，她不在这儿。

约翰：你能告诉她给我打电话吗？

琼：对不起，我不认识她。
