定语从句中,用that,what区别以及定语从句怎填写先行词,我老是搞混？
首先，定语从句的关系词分为关系代词和关系副词 关系代词有 that/who指代人，作主语 whom/that指代人，作宾语 whose表示所有格 which/that/as指代物，作主语或宾语 关系副词有when/where/why/介词 when/which的结构 所以在定语从句中，关系词中没有what的，what是用来引导名词性从句的 其次，先行词指的是被定语从句所修饰的名词，代词，可以根据从句来填写 有不会的可以再问我
What引导的主语从句如何改为that引导？
把What引导的主语从句改为that引导是：把what改为all that.
what引导的主语从句表示“所……的”。例句：
1.What you did is right.
改为that引导是：
All that you did is right.
2.What he told me is true.
改为that引导是:
All that he told me is true.
3.What she bought is very expensive.
改为引导that是：
All that she bought is very expensive.
What is it句型如何讲解？
怎么理解 what is it you want to do 分析下语法？
答：我的理解就是，它是What is it that you want to do 这个强调句型的特殊疑问句之漏打了一个词that.
请看句子的变化过程：
I want to join the army. 肯定句。我想参军。
就join the army 提问：
What do you want to do 你想干什么？《---You want to do what
就句中的what进行强调：
It is what that you want to do.
一般疑问：Is it what that you want to do
特殊疑问：What is it that you want to do
译：你想做的（究竟）是什么？
