现阶段，好多同学在根本上区分三大从句还是存在一定的问题，今天，海天考研在这里给大家提几点学习三大从句中的注意点，以便大家学习。

　　第一，明确三大从句到底是?

　　三大从句具体为名词性从句，定语从句和状语从句。其中名词性从句又包括主语从句，宾语从句，表语从句和同位语从句。

　　第二，同位语从句及定语从句，花开两家的依据是?

　　市面上语法辅导教材鱼龙混杂，各家之言遍地开花，那这个时候，同学们一定要淡定， 不要东求一下，西看一下，要端正自己的态度，保持自己的基调。其实，说到底，考研依然是应试型考试，所以只要找到他们二者做题时可以区别的标志就好了。

　　同位语从句中that有三不定律：

　　1.不做成分;

　　2.不可省略;

　　3.没有任何意义。

　　定语从句中that职责是指代先行词并在从句中做主语或是宾语的。

　　接下来，海天考研给大家准备了一些练习答疑过程中同学问题比较多的题目，供考生们学习分析。
