Question

of后面引导的是什么从句?引导词用什么?怎么区分?
The most important one of which is called carbon dioxide.
All of which will make life for human beings better.
They are accepted as the beginning of what we called modern art.
帮我分析一下这3个句子of 后的从句,以及为什么用which/what?而不用另一个.

Answer 1

The most important one of which is called carbon dioxide.
All of which will make life for human beings better.
这两个句子前面应该还有句子,which都是指代前面的内容
of 后面只是用用了关系词 which
They are accepted as the beginning of what we called modern art.
of 后面what we called modern art 是做介词 of 的宾语 ,介词宾语 ,what引导的宾语从句 ,
which 多用于定语从句 ,指代已知的内容
what多用于引导 主语,宾语从句 ,指代未知的内容
