英语形容词作名词
A liquid that might be a poor conductor when pure is often used to make solutions that readily transmit electricity.请问在本句话的从句中（即when后的句子里）为什么形容词pure可以作主语?为什么不写成purity?

英语形容词作名词A liquid that might be a poor conductor when pure is often used to make solutions that readily transmit electricity.请问在本句话的从句中（即when后的句子里）为什么形容词pure可以作主语?为什么不
是这样的.
先分析句子成分.
A liquid主语,后面that引导定语从句.that might be a poor conductor.when引导状语从句,省略it is.it 指代的是a liquid.
从句完了,is 就是动词,后面的often used to make solutions是宾语.之后的that引导的定语从句.

A liquid (that might be a poor conductor when pure) is often used to make solutions that readily transmit electricity

A liquid / that might be a poor conductor when (it is)pure / is often used to make solutions that readily transmit electricity
/ that might be a poor conductor when (it is)pure /是定语从句

可能这个单词少了一个引号，作者是引用这个单词。就像这样的：
"Beautiful" is often used to express a girl.
