解析
【分析】
本题需用because（引导原因状语从句）或if（引导条件状语从句）改写画线句子，核心是先判断每组句子的逻辑关系：1. 句1是“原因（年轻人了解琼剧少）→结果（需要教他们）”的因果关系；2. 句2是“条件（不快速行动）→结果（传统艺术消失）”的条件关系；3. 句3是“结果（向老艺术家求助）→原因（他们熟悉歌曲和故事）”的因果关系；4. 句4是“条件（在学校演出）→结果（更多学生爱上琼剧）”的条件关系，再对应使用连词改写。
【解析】
1. 句1：因果关系，用because引导原因状语从句，将原因放从句前，结果放主句后，改写为：Because few young people know about Qiongju today, we need to teach them.
2. 句2：条件关系，用if引导否定的条件状语从句，即“如果不行动”，改写为：If we don't act fast, this traditional art will be lost.
3. 句3：因果关系，用because引导原因状语从句，将原因放主句后，结果放主句前，改写为：We can ask old Qiongju artists for help because they know the songs and stories well.
4. 句4：条件关系，用if引导条件状语从句，将条件放从句前，结果放主句后，改写为：If we put on shows at school, more students will fall in love with Qiongju.
【答案】
1. Because few young people know about Qiongju today, we need to teach them.
