I lost the photocopy

[Maggieda]

"Duì bu qǐ, shí´er yuè shí hào shì wǒ péngyou de shēngri". These sentences belong to the book The Great Wall Chinese, Essentials in Communication, Unit One, Lesso Two". As I lost the photocopy I would like to get the whole dialogue with pinyins and characters. Can anyone help me? Thanks and greetings. Maggie

How do you know the sentence if you lost the copy? Is it the copy of the book?
I think the book is also in the library of my university. Next weekend I can have a look. It seems your neither German native nor Chinese native, where are you from?
