can't insert or duplicate blank pages?!!

I"m using Pages 09 and I notice that you can't insert blank pages where you want. They appear at the bottom of the page. Not cool. In addition, to bypass this I thought I would duplicate a page and then just erase the content. Doesn't work! When you duplicate a page it duplicates all the pages in the document. This doesn't make sense. Can someone explain how to insert a blank page anywhere in my 44 page document without it appearing at the the end or duplicating a single page and not every page?
