what做主语,同时也是连接词.因为what做主语,本来特殊疑问句就是陈述语序,所以不用改变什么.
where做状语,同时也是连接词.因为where不做主语,所以原来疑问句用疑问语序,变成宾语从句时要变成陈述语序.
类似的句子有what is wrong with you?what made you sad?who loves you?what is the matter with you?what happened?what is up?who did it?what troubled you?这些句子都是what who做主语,虽然是特殊疑问句,确实陈述语序.变成宾语从句时,语序不发生变化.
