She is very tall ,as is her mother.
问题描述：
She is very tall ,as is her mother.
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
答
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 v...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。
