我认为非常有帮助的用户给了你一个错误的答案。下面是一个我认为更好的例子：

 //The ID of the parent page, for example 4. Change to the correct ID.
 //For example, if you are in the page loop, you can use get_the_ID() to get ID of current page
 $parent_id = 4;

 //The terms that the page belongs to.
 $terms = array( \'one_term\', \'another_term\' );

 $args = array(
      \'post_type\'   => \'page\',
      \'post_parent\' => $parent_id,
      \'tax_query\'   => array(
            array(
                \'taxonomy\' => \'top5\',
                \'field\'    => \'name\',
                \'terms\'    =>  $terms
           )
       )
 );

 $query = new WP_Query( $args );

 if ( $query->have_posts() ) {

     //Start the loop
     while ( $query->have_posts() ) {

         $query->the_post();

         //Do whatever you want with the found pages. For example:
         the_title();
         if( has_post_thumbnail() ) {
             the_post_thumbnail();
     }
         the_content();

     }
     //End the loop

     wp_reset_postdata();

  } else {

    //Do something if pages have not been found

  }

注意：默认情况下，“pages”没有分类法，因此我假设您已经为“pages”帖子类型注册了“top5”分类法。另外，您说您想要获取页面的摘录，默认情况下，页面不支持摘录，因此我假设您添加了对页面的摘录支持。
