您必须不断重置$post变量，以推进循环post计数器。

使用类似以下内容：

    global $post;
    get_header(); ?>

    <div id="container">
        <div id="content" role="main">

        <?php
        /* Run the loop to output the post.
         * If you want to overload this in a child theme then include a file
         * called loop-single.php and that will be used instead.
         */
        if(have_posts()) while(have_posts()): the_post();
            the_title();
            for($i = 0;$i < 4;$i++)
            {
                $post = get_next_post();
                setup_postdata($post);
                if(!empty($post))
                {
                    echo \'<br/>\';
                    the_title();
                    //or whatever code you need to output
                }
                else
                {
                    //no next post found
                }
            }
        endwhile;
        wp_reset_postdata();
        ?>

        </div><!-- #content -->
    </div><!-- #container -->
