I only want to download the pages related to a category,such as "culture" or "history" category.
Go to http://en.wikipedia.org/wiki/Special:Export In "Add pages from category" insert: History and press Add. A list of all articles in History category will fill the box.
You can add the contents of more categories and they will be added at the bottom. Finally, press Export to download a dump of those pages selected (you can also manually add/remove them in the textbox).
Caveat: Adding the contents of Category:History will add the articles directly at Category:History, but not those at Category:Historians, which is a subcategory of History.
