think that you know what in fact you do not know is为什么用that和what
问题描述:
think that you know what in fact you do not know is为什么用that和what
答
that 引导的是宾语从句,指代的是that后面的整个从句。而what引导的是know的内容,what you in fact you don't后实际上是承前省了一个know。
答
老兄 这个问题怎么看着那么费解啊 能不能给个完整的句子~~~
答
用that是因为在think后面引导宾语从句,用what是因为know是及物动词后面必须有宾语,这里疑问词what可以做know的宾语,而that不行.
