我已经从Wordpress文档中复制了有关使用将分页添加到自定义查询的代码\'paged\' => $paged. 然而，在我的页面上，它不起作用。我做错了什么？？

  <?php 
      $paged = ( get_query_var( \'paged\' ) ) ? get_query_var( \'paged\' ) : 1;
      $args = array(\'post_type\' => \'post\', \'posts_per_page\' => 10, \'paged\' => $paged); 
      $the_query = new WP_query($args); 
      if ( $the_query->have_posts() ) : ?> 
        <ul class="pis-ul">
      <?php while ( $the_query->have_posts() ) : $the_query->the_post(); ?>
           <li class="pis-li">
                 <a class="pis-title-link" href="<?php echo the_permalink(); ?>">
                 <div class="news-thumbnail">

                 <?php

                    if(has_post_thumbnail()) {
                     echo the_post_thumbnail(\'news-thumbnail\');  
                    }

                    ?>
                    </div>
                    <p class="pis-title">
                        <?php the_title(); ?>       
                    </p>
                    <p class="pis-excerpt">
                        <?php the_excerpt(); ?>
                    </p>
                    <p class="pis-utlility">
                        <span class="pis-date">Published on <?php echo the_date(); ?></span>
                    </p>
                 </a>     
            </li>
      <?php endwhile; ?>
        <ul>
      <div class="nav-previous alignleft"><?php next_posts_link( \'Older posts\' ); ?></div>
      <div class="nav-next alignright"><?php previous_posts_link( \'Newer posts\' ); ?></div>

      <?php else:  ?>
        <p>
          <?php _e(\'Sorry, this page does not exist.\'); ?>
        </p>
        <?php endif; ?>
