Blog and News Page Template

How can I get the Blog and News Page Template to show the summary version of Blog's (like the Blog Archive Widget) so people can "click here to read more"............otherwise people have to scroll down a long ways to see all the Blog Post and Categories. Would be nice to have the html code to put all the Blog Categories into a regular page. There must be a way to accomplish this. Please advise. My website: http://www.gohealthynext.com Thanks
