<?php
$termid=taxonomy_get_children(arg(2));
           foreach($termid as $terid){
                $a=taxonomy_select_nodes($terid->tid,$pager = TRUE, $limit = 1, $order = array('t.created' => 'DESC'));
               foreach($a as $nid){
                $node_this = node_load($nid);
                echo '<h1 class="pdtitle"><a href="#">'.$node_this->title.'</a></h1>';
}
?>

how to add pager to it, when i add $pager = TRUE, $limit = 1, it doesn't work.
