01）找到includes/lib_article.php 文件的第21行，将下面方法覆盖原方法。

/**
* 获得文章分类下的文章列表
*
* @access public
* @param integer $cat_id
* @param integer $page
* @param integer $size
*
* @return array
*/
function get_cat_articles($cat_id, $page = 1, $size = 20 ,$requirement='')
{
//取出所有非0的文章
if ($cat_id == '-1')
{
$cat_str = 'cat_id > 0';
}
else
{
$cat_str = get_article_children($cat_id);
}
//增加搜索条件，如果有搜索内容就进行搜索
if ($requirement != '')
{
$sql = 'SELECT article_id, title,content , author, add_time, file_url, open_type' .
' FROM ' .$GLOBALS['ecs']->table('article') .
' WHERE is_open = 1 AND title like \'%' . $requirement . '%\' ' .
' ORDER BY article_type DESC, article_id DESC';
}
else
{

$sql = 'SELECT article_id, title,content , author, add_time, file_url, open_type' .
' FROM ' .$GLOBALS['ecs']->table('article') .
' WHERE is_open = 1 AND ' . $cat_str .
' ORDER BY article_type DESC, article_id DESC';
}

$res = $GLOBALS['db']->sel ectLimit($sql, $size, ($page-1) * $size);

$arr = array();
if ($res)
{
while ($row = $GLOBALS['db']->fetchRow($res))
{
$article_id = $row['article_id'];

$arr[$article_id]['id'] = $article_id;
$arr[$article_id]['title'] = $row['title'];
/*68ecshop.com  add*/
$arr[$article_id]['content'] = $row['content'];

$arr[$article_id]['short_title'] = $GLOBALS['_CFG']['article_title_length'] > 0 ? sub_str($row['title'], $GLOBALS['_CFG']['article_title_length']) : $row['title'];
$arr[$article_id]['author'] = empty($row['author']) || $row['author'] == '_SHOPHELP' ? $GLOBALS['_CFG']['shop_name'] : $row['author'];
$arr[$article_id]['url'] = $row['open_type'] != 1 ? build_uri('article', array('aid'=>$article_id), $row['title']) : trim($row['file_url']);
$arr[$article_id]['add_time'] = date($GLOBALS['_CFG']['date_format'], $row['add_time']);
}
}

02）article_cat.dwt文件循环文章的时候，添加红色代码，CSS样式自己调。
      <!-- {foreach from=$artciles_list item=article} -->
      <p><a href="{$article.url}" title="{$article.title|escape:html}">{$article.short_title}</a>
      </p>


<div style="border:1px solid #E8E8E8; padding:10px; margin:10px 0; color:#999">
      {$article.content|strip_tags|truncate:40}<a href="{$article.url}" title="{$article.title|escape:html}">[详情进入]</a>
      </div>



      <!-- {/foreach} -->
