书本上的例句是：I just don't what to expect. It really scares me
改为What really scares me is I just dont't know what to expect，请问这个是什么语法问题，改为什么句子了
还有三个题目，请帮忙把下列三句子按上面格式改写，详细点解析下，谢谢
1：I don't know how to tell her the bad news,It troubles me most
2:What will I do after graduation? My father is always concerned about it.
3:He passed the exam,which really surprise each of us.

Answer 1

这个是名词性从句 的用法 问题
下面 是 用名词性从句 合并句子 

What troubles me most is that I don't know how to tell her the bad news。主从和表从

或that I don't know how to tell her the bad news troubles me most主从


What I will do after graduation always concerns my father.主从

或My father is always concerned about What I will do after graduation.宾从

What really surprises each of us is that he passed the exam主从和表从
