what后是主谓结构,这种说法很奇怪,what引导
名词性从句,在从句中可作主语,宾语,表语,一般并不会翻译成不论,如楼上所说,表达这个意思应该用whatever,这个词既可以引导名词性从句,也可以引导
让步状语从句。
我觉得你先要掌握what引导名词性从句的基本结构,和that的区别,多背几个例句,然后再写。
例如:
The important thing is what you do, but not what you say.(what引导
表语从句,在从句中做宾语)
What caused the accident is still a complete mystery.(what引导
主语从句,在从句中做主语)
it is not important that what is writen in the letter.
这个句子里it是
形式主语,真正的主语是that从句,也就是说that引导主语从句,既然是从句,那就是个句子,比如:It's not important that you don't like pop music.你不喜欢流行乐并不重要。that后边是个完整的句子,因为that在名词性从句中无意义无成分。你的句子在that从句里有且仅有一个what引导的从句,这在语法上是不成立的。想要表达你的意思可以说What is in the letter is not important.这是what引导的主语从句,what在从句中做主语。
