代替slideshow_featured_posts 该教程的功能包括：

function slideshow_featured_posts() {

    $featured = 1; // Assuming that the name of the category ID number 1 is "Featured".
    $count = 3; // How many post to be shown as slides. Ideally, it should be more than 3 posts.
    add_filter(\'excerpt_length\', \'hook_excerpt_featured_length\');
    $Silder_query = new WP_Query(array(\'cat\' => $featured, \'posts_per_page\' => $count));
?>

<div class="list">
    <?php while ($Silder_query->have_posts()) : $Silder_query->the_post(); ?>
    <div class="item">
        <a class="image" href="<?php the_permalink(); ?>" title="Permanent Link to <?php the_title_attribute(); ?>">
        <?php the_post_thumbnail(\'slideshow\'); ?>
        </a>
        <div class="meta">
            <h3><a href="<?php the_permalink(); ?>" title="Permanent Link to <?php the_title_attribute(); ?>"><?php the_title(); ?></a></h3>
            <?php the_excerpt(); ?>
        </div>
        <div style="clear: both"></div>
    </div>
    <?php endwhile; ?>
