如果词序是倒装形式，就错了：
……who was that girl.
……if was she free.
……whether could I help her.
关于间接疑问句，还有一点必须注意的是，直接疑问句里的疑问词要照用， 如例⑧的“who”。如果没有疑问词，就要借重连接词“ if”或“ whether”之助，如例⑨和⑩便是。
在结束本文之前，顺便提一提怎样把表示惊叹或愿望的直接引语转成间接引语。
11. He said, "Alas! I am undone."
12. "Bravo! You have done a good job, Mary," said the teacher.
13. "Good Heaven!' Tom cried, "I'll never lie again."
把11-13，转变为14-16时， 可以用恰当的动词把深层的意思反映出来，甚至加些原文没有的字眼，也无所谓：
14. He exclaimed that he was undone.
15. The teacher praised Mary, saying that she had done a good job.
16. Tom called upon Heaven to witness his determination not to lie again.
