英语长短句成分分析
•It therefore becomes more and more important that, if students are not to waste their opportunities, there will have to be much more detailed information about courses and more advice.
But now it is realized that supplies of some of them are limited, and it is even possible to give a reasonable estimate of their “expectation of life”, the time it will take to exhaust all known sources and reserves of these materials.
Prior to the twentieth century, women in novels were stereotypes of lacking any features that made them unique individuals and were also subject to numerous restrictions imposed by the male-dominated culture.
请大神帮帮分析句子成分（主句，状从，宾从等等）

Answer 1

It therefore becomes more and more important that, if students are not to waste their opportunities, there will have to be much more detailed information about courses and more advice.（that开始到句末都是主语从句，if到opportunities是主语从句中的条件状语从句）
But now it is realized that supplies of some of them are limited, and it is even possible to give a reasonable estimate of their “expectation of life”, the time it will take to exhaust all known sources and reserves of these materials. （that开始到limited是主语从句，the time后面是定语从句）
Prior to the twentieth century, women in novels were stereotypes of lacking any features that made them unique individuals and were also subject to numerous restrictions imposed by the male-dominated culture.（that开始到individuals是定语从句）
