1)一般情况下,即使是有疑问词, 从句仍然是陈述句式,如;
This book will show you what the best CEOs know.
Can you figure out what the poet really means in this poem.
2)但个别宾语从句本应用陈述语序,可由于习惯而保持原疑问语序不变,如;
I don't know what is the matter with him.
I have no idea what was the matter with him.
关于matter的从句都是疑问语序就是说I don't know 后面都是保持原疑问语序不变？不是。只是个别的。个别的。。比如？呃。。。我现在只知道what is wrong with sb/what is the matter with sb。在这两个句型中，主语是what，谓语是is 。它们既是疑问语序，也是陈述语序。
