您需要使用offset WP\\U查询中的参数，例如。

<?php
        $loop = new WP_Query( array( \'post_type\' => \'recentproject\', \'orderby\' => \'rand\', \'posts_per_page\' => \'1\') );
        $counter=0;
        ?>
        <?php while ( $loop->have_posts() ) : $loop->the_post(); $counter++; ?>
        <div class="col-8 columns">
            <?php edit_post_link(); // Always handy to have Edit Post Links available ?>
            <?php if ( has_post_thumbnail()) : // Check if thumbnail exists ?>
                <?php echo get_the_post_thumbnail(); ?>
            <?php endif; ?>
        </div>

        <div class="col-4 columns">
            <h4 class="project_title"><?php the_title(); ?></h2>
            <?php echo the_content(); ?>
        </div>
    <?php endwhile; ?>
    <div class="clear"></div>
    <div class="row">
        <?php
        $loop = new WP_Query( array( \'post_type\' => \'recentproject\', \'orderby\' => \'rand\', \'posts_per_page\' => \'3\', \'offset\' => \'1\' ) );
        ?>
        <?php while ( $loop->have_posts() ) : $loop->the_post(); ?>
            <div class="col-4 columns">
                <h4 class="project_title"><?php the_title(); ?></h4>
                <?php edit_post_link(); // Always handy to have Edit Post Links available ?>
                <?php if ( has_post_thumbnail()) : // Check if thumbnail exists ?>
                    <?php echo get_the_post_thumbnail(); ?>
                <?php endif; ?>
                <?php echo the_content(); ?>
            </div>
        <?php endwhile; ?>
    </div>

基本上，它会忽略查询中的前xx篇文章，因此如果要忽略查询中的第一篇文章，可以使用offset=>1

我不认为它会与“兰德”订单一起工作，但兰德是必要的吗？Edit: Using count & 1 query

<?php
$loop = new WP_Query( array( \'post_type\' => \'recentproject\', \'orderby\' => \'rand\', \'posts_per_page\' => \'4\') );
$count = 1;
while ( $loop->have_posts() ) : $loop->the_post();
 if($count == \'1\') { ?>
  <div class="col-8 columns">
   <?php edit_post_link(); // Always handy to have Edit Post Links available ?>
   <?php if ( has_post_thumbnail()) : // Check if thumbnail exists ?>
    <?php echo get_the_post_thumbnail(); ?>   
   <?php endif; ?>
  </div>

  <div class="col-4 columns">
   <h4 class="project_title"><?php the_title(); ?></h4>
    <?php echo the_content(); ?>
  </div>
 <?php } else { ?>

  <div class="col-4 columns">
   <h4 class="project_title"><?php the_title(); ?></h4>
   <?php edit_post_link(); // Always handy to have Edit Post Links available ?>
    <?php if ( has_post_thumbnail()) : // Check if thumbnail exists ?>
     <?php echo get_the_post_thumbnail(); ?>
    <?php endif; ?>
    <?php echo the_content(); ?>
   </div>

  <?php
  }
 $count++;
endwhile;
wp_reset_postdata();
?>

未测试，但应该可以工作，基本上它会统计帖子，并根据计数更改HTML代码
