as is vividly indicated in the above chart,这句话怎么理解其结构?总感觉as is 怪怪的~还原就对了么?我总感觉as it顺~可貌似语法不对~求教~
是对句子不是很明白~
答
这句话的意思是"在以上的图表中形象的显示了,一个男青年正坐在......"
答
AS引导了非限制定于从句（和WHICH一样,但WHICH只能用在句中）
也就是说,AS后面句子的主语其实就是逗号之后的句子
所以你看不到IT
还原的话就是
a young guy is sitting on the ……,as is vividly indicated in the above chart.
或者可以这样
that a young guy is sitting on the ……is vividly indicated in the above chart.
其中that可以是句子名词化,这样就可以做主语了,不然一个句子是无法做主语的,也就是为什么你那句话里用了AS的原因了～～
