Using loops you can show wordpress content.If you want to show the full content for the first two posts and then just the excerpt for the rest then this code is for you.
[php] <?php
$page = (get_query_var(‘paged’)) ? get_query_var(‘paged’) : 1;
query_posts("paged=$page&posts_per_page=5"); ?>

<?php $count = 1; // Sets count to 1 on first output post ?>

<?php while (have_posts()) : the_post(); ?>

<?php if ((!is_paged()) && ($count == 1 || $count == 2)){ // THIS STARTS FULL CONTENT IF IS FIRST POST AND NOT PAGED, THE OR OTHER COUNT ALLOWS FOR SHOWING MORE THAN ONE OF THE FULL CONTENT POSTS BEFORE GOING TO EXCERPTS ?>

<?php the_content(); ?>

<?php } else { // THIS ends FULL CONTENT and SHOWS FOLLOWING POSTS ELSE ?>

<?php the_excerpt(); ?>

<?php } $count++; // THIS IS the END of ELSE and sets count one up ?>

<?php endwhile; ?>
?>
[/php]
