特别注意：
1、如果用户需要检索学段，比如小学，初中，需要先到
select stage_id from t_crawler_stage where stage_name='小学'
用得到stage_id再与其它表进行关联查询，不要直接使用学段名称进行查询。
2、如果用户需要检索科目，比如语文，数学，需要先到
select subject_id from t_crawler_subject where subject_name='语文'

用得到subject_id再与其它表进行关联查询，不要直接使用科目名称进行查询。
3、凡是涉及到行政区划,也就是gather_regionc字段的，不能直接从t_crawler_lesson表中读取，它没有这个列，
需要通过lesson_id 关联到t_crawler_lesson_school表中，再从t_crawler_lesson_school表中读取。
