Add regular blog posts after single post?

Hey, i want to set my blog up, so if i send a link to someone of single post, they will click and see it, but they will also see the cycle of regular posts below. I need this so when people visit my sight, they will stay and look around instead of hitting the back button.

Im trying to copy the main segment out of index.php and insert it in single.php. Does anyone know which portions you copy and if i need to change any of the code manually?? thanks!
