不明白what从句,在这个句子的成分?

A little bit of background is needed to understand what contrasting Italian brands set one another.
这里边what引导的是什么从句?这个句子的成分划分是什么?

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。

“what contrasting Italian brands set one another. “ 是 is needed to understand 的宾语从句
A little bit of background is needed to understand what contrasting Italian brands set each other. 在了解这些意大利品牌之间的差异之前,有必要先提一下法国高级定制。追问

那understand 在这里是什么成分呀?

追答

个人理解: 被动时态is needed 做谓语, 不定式 是目的状语 to understand what contrasting Italian brands set each other.

rectify改正后面的what引导的是宾语从句; what是described的宾语 what的意思是the +名词+ that(或者是all that)的意思 what it decribed as 本来结构: it(the foreign ministry) described what as America's mistake

what引导名词性从句。

1、Do you know what i did just now?(宾语从句)

2、What he said is very improtant(主语从句)

3、That is just what i want (表语从句)

4、What he said that we won the game makes me happy.(同位语从句,但在此,what引导的句子作主语,所以,在此,what引导的是主语从句)

你不觉得你采纳得有点可笑?
