使用多个循环时防止POST复制的最佳方法

我在我的网站上的一个页面上有以下循环。

修改下面的代码以阻止第一个循环中的帖子在第二个循环中重复的最好方法是什么？

    <?php query_posts(\'showposts=1&post_type=post\'); ?>

<?php if ( have_posts() ) : while ( have_posts() ) : the_post(); ?>
<div id="latestpost" <?php

    if ( $thumbnail_id = get_post_thumbnail_id() ) {
        if ( $image_src = wp_get_attachment_image_src( $thumbnail_id, \'normal-bg\' ) )
            printf( \' style="background-image: url(%s);"\', $image_src[0] );     
    }

?>>

    <article id="post-<?php the_ID(); ?>" <?php post_class(); ?>>
                    <a href="<?php the_permalink(); ?>" title="<?php the_title(); ?>">



    <h2><?php the_title() ;?></h2>      
    <div class="summary" style="color:#fff;">
        <?php the_excerpt(); ?>
        </div>
    <!-- <?php the_post_thumbnail(); ?> -->
<?php endwhile; else: ?>

    <p>Sorry, there are no posts to display</p>
                    </a><!-- permalink -->
<?php endif; ?>
    </article>
</div><!-- latest post -->

<?php wp_reset_query(); ?>


<div id="postlist">

<h2>Personal finances</h2>

<?php query_posts(\'showposts=3&post_type=post&category_name=Personal\');
 ?>

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

    <!-- article -->
    <article id="post-<?php the_ID(); ?>" <?php post_class(); ?>>
        <!-- post title -->
        <div class="post-thumbnail">
        <!-- post thumbnail -->
        <?php if ( has_post_thumbnail()) : // Check if thumbnail exists ?>
            <a href="<?php the_permalink(); ?>" title="<?php the_title(); ?>">
                <?php the_post_thumbnail(array(120,120)); // Declare pixel size you need inside the array ?>
            </a>
        <?php endif; ?>
        <!-- /post thumbnail -->
        </div>

        <h3 class="postlist-article-header">
            <a href="<?php the_permalink(); ?>" title="<?php the_title(); ?>"><?php the_title(); ?></a>
        </h3>
        <!-- /post title -->


    </article>
    <!-- /article -->

<?php endwhile; ?>

<?php else: ?>

    <!-- article -->
    <article>
        <h2><?php _e( \'Sorry, nothing to display.\', \'html5blank\' ); ?></h2>
    </article>
    <!-- /article -->

<?php endif; ?>

<?php wp_reset_query(); ?>

$exclude = array(); if ( have_posts() ) : while ( have_posts() ) : the_post(); //first loop $exclude[] = get_the_ID(); ... //second loop $second_loop_args = array( \'showposts\' => 3, \'post_type\' => \'post\', \'category_name\' => \'Personal\', //should make sure you\'re using category slug here \'post__not_in\' => $exclude //this arg needs to be an array, hence moving from string to array format for query_post args ); query_posts($second_loop_args); ....
