Using query_posts
is asking for trouble, because its results may be unpredictable (read more about that in this post). In stead you should define a new query and loop through its results. Like this:
$args = array(
'category_name' => 'news',
'posts_per_page' => '3'
);
$the_query = new WP_Query( $args );
if ( $the_query->have_posts() ) {
while ( $the_query->have_posts() ) {
$the_query->the_post();
the_content();
}
}
wp_reset_postdata();
