听力原文：W: It is so nice here, so restful. I have never been here before.

M: No？

W: I think I shall come and sit here sometimes.

M: Yes？

W: Do you lock the hut when you're not here？

M: Yes, your Ladyship.

W: Do you think I could have a key too, so that I could sit here sometimes？ Are there two keys？

M: Not as far as I know, there's none.

W: Couldn't we get another key？

M: Another !

W: Yes, a duplicate.

M: It happens Sir Clifford would know.

W: Yes! He might have another. Otherwise we could have one made from the one you have. It would only take a day or so, I suppose. You could spare your key for so long.

M: I cannot tell you, your Ladyship! And I know nobody who makes keys round here.

W: Very well! I'll see to it.

M: All right, your Ladyship.

W: Good afternoon !

M: Afternoon, my Lady !
