She is very tall , as is her mother.

Question

非限制定从 as不是领导前面整个句子吗
那不就是她很高这件事 is her mother不是说不通吗
书上说是非限制定从作表语 不懂
为什么不是 as her mother is

Answer 1

一般我们as引导非限制性定语从句时，
它指代的是上文提及的整个句子。在定语从句中可作，主语、表语、宾语等。
She is very tall , as is her mother.
这个句子中as不是指代一个句子，指代的是very tall，
即：her mother is very tall。
那么，as就是作表语了，不是定语从句作表语，定语从句本身就是定语从句了。追问

为什么不是 as her mother is

追答

这个一个对等表语的问题，A=B，B=A，就像我们说的 i know who is he ，和 i know who he is 一样，两个都对。一般习惯用第一个。

Answer 2

她象她妈妈一样长得很高

后面是倒置，意思是她妈妈也很高， as 打头要倒装的

Answer 3

不是She is very tall , as is her mother. 因该是she is very tall as her mother 或者是she as tall as her mother
因为这个句子里面已经有as了 那就不用再加is进去了

Answer 4

She is very tall as her mother。
