疑问词引导
表"是否":whether/if
I wonder whether/if you will pass the CET4
I wonder <font color="#f15a23">whether or not</font> you will pass the CET4(只有whether能和or not连用)
<font color="#f15a23">wether </font>you will pass the CET4 is important(从句在句首时只能用wether)
I wonder <font color="#f15a23">wether/if</font> you will pass the CET4 <font color="#f15a23">or not</font>
表"啥"：when/were/why/who<br>whom/which/how/what
when you will pass the CET4 is a mystery
I don't know __ i can take the CET4
that引导
that后面是件事
It's clear that zongzi should be sweet
what后面是个问题
It's clear what should be sweet
<font color="#0076b3">去掉连接词，从句完整，用that；不完整，用what</font>
同位语从句与定语从句区别
同位语从句是对名词的再次说明-Bring the book <font color="#f15a23">that he loves me next time</font>
定于从句修饰名词-Bring the book <font color="#f15a23">that he loves next time</font>
<font color="#0076b3">去掉that，从句完整，是同位语从句；不完整是定于从句</font>
