名词从句讲解that和what怎么区分,
谁能帮我懂得来讲讲名词从句的语法知识
或其它从句的知识
答
他们都可充当主语,宾语,表语.区别在于that在句中不充当成份,而what充当成份
答
what表示“所...”
eg:
That's what I wanted to say
that引导的从句说明的是具体的一件事.
eg:That he didn't go to school made his monther angry.
引导that 在引导主语从句,表语和同位语从句时不能省略,在引导宾语从句时可以省略.
eg:He said (that) he had been to shanghai twice.
