问题补充：
The small children don know what is in their stockings为什么说后面的宾语从句为陈述语句?
答案：
宾语从句的语序是陈述句语序,即“连接词＋主语＋谓语＋其他”.这里特别强调的是,它的主语和谓语的语序是陈述句的语序,不是疑问句的倒装语序.
连接词＋谓语.连接词在从句中作主语.常见的连接词有：who,what,which等.如：
Could you tell me who knows the answer,please?你能告诉我谁知道答案吗?
The small children don know what is in their stockings．这些小孩子不知道袜子里有什么东西?
