<?php 

$news_cat_ID = get_cat_ID('News'); 
$news_cats = get_categories("parent=$news_cat_ID"); 
$news_query = new WP_Query; 

foreach ($news_cats as $news_cat) : 
    $news_query->query(array(
     'cat'     => $news_cat->term_id, 
     'posts_per_page'  => 1, 
     'no_found_rows'  => true, 
     'ignore_sticky_posts' => true, 
    )); 

    ?> 

    <h2><?php echo esc_html($news_cat->name) ?></h2> 

    <?php while ($news_query->have_posts()) : $news_query->the_post() ?> 

      <div class="post"> 
       <?php the_title() ?> 
       <!-- do whatever you else you want that you can do in a normal loop --> 
      </div> 

    <?php endwhile ?> 

<?php endforeach ?>

数小时后并感谢我们的同伴都在全球范围内，我已经能够修改主查询，所以我们甚至都不需要去模板，生成新的查询和循环..

// My function to modify the main query object 
function grouped_by_taxonomy_main_query($query) { 

    if ($query->is_home() && $query->is_main_query()) { // Run only on the homepage 

     $post_ids = array(); 

     $terms = get_terms('formato'); 

     foreach ($terms as $term) { 
      $post_ids = array_merge($post_ids, get_posts(array( 
       'posts_per_page' => 4, // as you wish... 
       'post_type' => 'video', // If needed... Default is posts 
       'fields' => 'ids', // we only want the ids to use later in 'post__in' 
       'tax_query' => array(array('taxonomy' => $term->taxonomy, 'field' => 'term_id', 'terms' => $term->term_id,)))) // getting posts in the current term 
      ); 
     } 

     $query->query_vars['post_type'] = 'video'; // Again, if needed... Default is posts 
     $query->query_vars['posts_per_page'] = 16; // If needed... 
     $query->query_vars['post__in'] = $post_ids; // Filtering with the post ids we've obtained above 
     $query->query_vars['orderby'] = 'post__in'; // Here we keep the order we generated in the terms loop 
     $query->query_vars['ignore_sticky_posts'] = 1; // If you dont want your sticky posts to change the order 

    } 
} 

// Hook my above function to the pre_get_posts action 
add_action('pre_get_posts', 'grouped_by_taxonomy_main_query');
