第一句: The most controversies are those about matters as to which there's no good evidence either way.
第二句: He will admit that the question is one to which there is no demonstrably right answers.
这篇文章都有 to which他们指的是什么呢,这种抽象的连接副词不是很明确,希望老师指点迷津,谢谢老师!
第一句中的as to which 和第二句中的 to which 都是介词+关系代词which引导定语从句修饰前面的名词。
关系代词引导定语从句时,不但可以是动词的宾语, 也可以是介词的宾语。介词+which可以在从句中作状语,也可以在从句中作定语。用哪个介词可能由被修饰名词决定,也可能由从句的谓语动词或某个名词决定。介词的位置可以有二种,第一种为介词留在原处,定语从句由which引导。第二种是介词位于which之前。后者是正式语体形式。例如:
This is the book which he has talked about.
which引导定语从句,并在从句中作介词about的宾语,about which在从句作状语。介词about是动词talked要求的。这种介词留在原处的用法为非正式语体。
This is the book about which he has talked.
about which 引导定语从句,which在从句中作about的宾语,介词短语在从句中作状语。
